What's New

Qualified small business payroll tax credit for increasing research activities.

For tax years beginning before January 1, 2023, a qualified small business may elect to claim up to $250,000 of its credit for increasing research activities as a payroll tax credit. The Inflation Reduction Act of 2022 (the IRA) increases the election amount to $500,000 for tax years beginning after December 31, 2022. The payroll tax credit election must be made on or before the due date of the originally filed income tax return (including extensions). The portion of the credit used against payroll taxes is allowed in the first calendar quarter beginning after the date that the qualified small business filed its income tax return. The election and determination of the credit amount that will be used against the employer's payroll taxes are made on Form 6765, Credit for Increasing Research Activities. The amount from Form 6765, line 44, must then be reported on Form 8974, Qualified Small Business Payroll Tax Credit for Increasing Research Activities.

For quarters beginning before January 1, 2023, the payroll tax credit can be used only against the employer share of social security tax for the quarter and any remaining credit is carried forward to the next quarter. Starting in the first quarter of 2023, the payroll tax credit is first used to reduce the employer share of social security tax up to $250,000 per quarter and any remaining credit reduces the employer share of Medicare tax for the quarter. Any remaining credit, after reducing the employer share of social security tax and the employer share of Medicare tax, is then carried forward to the next quarter. Form 8974 is used to determine the amount of the credit that can be used in the current quarter. Corrections to this credit are made on Form 943-X, line 13. If you make a correction to Form 943-X, line 13, you must attach a corrected Form 8974. For more information, see the Instructions for Form 8974 and go to IRS.gov/ResearchPayrollTC.

This is an Image: caution.gifIf you claimed the credit for qualified sick and family leave wages for leave taken after March 31, 2020, and before April 1, 2021, and you make any corrections on Form 943-X to amounts used to figure this credit, you'll need to refigure the amount of this credit using Worksheet 1. You'll also use this worksheet to figure this credit if you’re claiming it for the first time on Form 943-X. If you claimed the credit for qualified sick and family leave wages for leave taken after March 31, 2021, and before October 1, 2021, and you make any corrections on Form 943-X to amounts used to figure this credit, you'll need to refigure the amount of this credit using Worksheet 3. You'll also use this worksheet to figure this credit if you’re claiming it for the first time on Form 943-X. If you claimed the employee retention credit for wages paid after March 12, 2020, and before July 1, 2021, and you make any corrections on Form 943-X to amounts used to figure this credit, you'll need to refigure the amount of this credit using Worksheet 2. You'll also use this worksheet to figure this credit if you’re claiming it for the first time on Form 943-X. If you claimed the employee retention credit for wages paid after June 30, 2021, and before January 1, 2022, and you make any corrections on Form 943-X to amounts used to figure this credit, you'll need to refigure the amount of this credit using Worksheet 4. You'll also use this worksheet to figure this credit if you’re claiming it for the first time on Form 943-X. If you claimed the COBRA premium assistance credit and you make any corrections on Form 943-X to amounts used to figure this credit, you'll need to refigure the amount of this credit using Worksheet 5. You'll also use this worksheet to figure this credit if you’re claiming it for the first time on Form 943-X.

Reminders

This is an Image: taxtip.gifIf a line on Form 943-X doesn't apply to you, leave it blank. If you're correcting a year before 2020, you must leave blank lines 7, 8, 14, 15a, 21, 22, 23, 24a, 26, 27, 28, 29, and 30. If you're correcting a year before 2021, you must leave blank lines 15b, 15c, 15d, 24b, 24c, 31, 32, 33, 34, 35, 36, 37, and 38. If you're correcting a year after 2021, you must leave blank lines 15a, 24a, 28, 29, 37, and 38.

The COVID-19 related credit for qualified sick and family leave wages is limited to leave taken after March 31, 2020, and before October 1, 2021.

The credit for qualified sick and family leave wages, as enacted under the Families First Coronavirus Response Act (FFCRA) and amended and extended by the COVID-related Tax Relief Act of 2020, is for leave taken after March 31, 2020, and before April 1, 2021, and the credit for qualified sick and family leave wages under sections 3131, 3132, and 3133 of the Internal Revenue Code, as enacted under the American Rescue Plan Act of 2021 (the ARP), is for leave taken after March 31, 2021, and before October 1, 2021. For more information about the credit for qualified sick and family leave wages, go to IRS.gov/PLC.

Corrections to amounts reported on Form 943, lines 2a, 2b, 12b, 14d, 18, and 19, for the credit for qualified sick and family leave wages for leave taken after March 31, 2020, and before April 1, 2021, are reported on Form 943-X, lines 7, 8, 14, 23, 26, and 27, respectively.

Corrections to amounts reported on Form 943, lines 12d, 14f, 22, 23, 24, 25, 26, and 27, for the credit for qualified sick and family leave wages for leave taken after March 31, 2021, and before October 1, 2021, are reported on Form 943-X, lines 15b, 24b, 31, 32, 33, 34, 35, and 36, respectively.

The COVID-19 related employee retention credit has expired.

The employee retention credit enacted under the Coronavirus Aid, Relief, and Economic Security (CARES) Act and amended and extended by the Taxpayer Certainty and Disaster Tax Relief Act of 2020 was limited to qualified wages paid after March 12, 2020, and before July 1, 2021. The employee retention credit under section 3134 of the Internal Revenue Code, as enacted by the ARP and amended by the Infrastructure Investment and Jobs Act, was limited to qualified wages paid after June 30, 2021, and before October 1, 2021, unless the employer was a recovery startup business. An employer that was a recovery startup business could also claim the employee retention credit for qualified wages paid after September 30, 2021, and before January 1, 2022. For more information about the employee retention credit, including an eligibility checklist, frequently asked questions, information on identifying employee retention credit scam promotions, and directions on how to withdraw a previously filed claim for the employee retention credit, go to IRS.gov/ERC.

Corrections to amounts reported on Form 943, lines 12c, 14e, 20, and 21, for the employee retention credit are reported on Form 943-X, lines 15a, 24a, 28, and 29, respectively. However, how you figure the employee retention credit for qualified wages paid after March 12, 2020, and before July 1, 2021, is different from how you figure the credit for qualified wages paid after June 30, 2021, and before January 1, 2022. For corrections to qualified wages paid after June 30, 2021, you may need to complete line 37 to tell us if you're eligible for the employee retention credit solely because your business is a recovery startup business. For corrections to qualified wages paid after September 30, 2021, you may need to complete line 38 to tell us if you’re eligible for the employee retention credit solely because your business is a recovery startup business.

Credit for COBRA premium assistance payments is limited to periods of coverage beginning on or after April 1, 2021, through periods of coverage beginning on or before September 30, 2021.

Section 9501 of the ARP provides for COBRA premium assistance in the form of a full reduction in the premium otherwise payable by certain individuals and their families who elect COBRA continuation coverage due to a loss of coverage as the result of a reduction in hours or an involuntary termination of employment (assistance eligible individuals). This COBRA premium assistance was available for periods of coverage beginning on or after April 1, 2021, through periods of coverage beginning on or before September 30, 2021. A premium payee was entitled to the COBRA premium assistance credit at the time an eligible individual elects coverage. Therefore, other than in rare circumstances, due to the COBRA notice and election period requirements (generally, employers have 60 days to provide notice and assistance eligible individuals have 60 days to elect coverage), January 2022 was generally the end of the period in which an assistance eligible individual would have elected coverage. Under some rare circumstances, it may be possible for a premium payee to become entitled to the COBRA premium assistance credit after January 2022. In these rare instances, the credit is still claimed on Form 943 filed for 2022 and an adjustment, if needed, can be made on Form 943-X for 2022. Employers eligible to claim the COBRA premium assistance credit after 2022 must file Form 943-X to claim the credit.

For more information on COBRA premium assistance payments and the credit, see Notice 2021‐31, 2021‐23 I.R.B. 1173, available at IRS.gov/irb/2021-23_IRB#NOT-2021-31; and Notice 2021-46, 2021-33 I.R.B. 303, available at IRS.gov/irb/2021-33_IRB#NOT-2021-46.

Corrections to amounts reported on Form 943, lines 12e, 12f, and 14g, for the COBRA premium assistance credit are reported on Form 943-X, lines 15c, 15d, and 24c, respectively.

Payroll tax credit for certain tax-exempt organizations affected by qualified disasters.

Section 303(d) of the Taxpayer Certainty and Disaster Tax Relief Act of 2020 allows for a payroll tax credit for certain tax-exempt organizations affected by certain qualified disasters not related to COVID-19. This credit is claimed on Form 5884-D. If applicable to the year that you're correcting, you'll enter the credit claimed on Form 5884-D on Worksheet 1 to figure your credit for qualified sick and family leave wages for leave taken before April 1, 2021, or Worksheet 2 to figure the employee retention credit for wages paid after March 12, 2020, and before July 1, 2021. For more information about this credit, go to IRS.gov/Form5884D.

Employee consents to support a claim for refund.

Rev. Proc. 2017-28, 2017-14 I.R.B. 1061, available at IRS.gov/irb/2017-14_IRB#RP-2017-28, provides guidance to employers on the requirements for employee consents used by an employer to support a claim for refund of overcollected social security tax and Medicare tax. The revenue procedure clarifies the basic requirements for both a request for employee consent and for the employee consent, and permits a consent to be requested, furnished, and retained in an electronic format as an alternative to a paper format. The revenue procedure also contains guidance concerning when an employer may claim a refund of only the employer share of overcollected social security tax and Medicare tax. The revenue procedure requires that any request for consent include an Additional Medicare Tax notice indicating that any claim on the employees’ behalf won’t include a claim for overpaid Additional Medicare Tax.

Correcting federal income tax withheld.

Generally, you may only correct administrative errors to federal income tax withholding (that is, errors in which the amount reported on Form 943, line 8, isn't the amount you actually withheld from an employee’s wages) and errors for which section 3509 rates apply. See section 13 of Pub. 15, Employer's Tax Guide, for more information about corrections during the calendar year and about administrative errors. See section 2 of Pub. 15 for more information about section 3509. If section 3509 rates apply, see the instructions for lines 16–19, later.

This is an Image: caution.gifOnly transposition or math errors involving the inaccurate reporting of the amount actually withheld are administrative errors.

You can’t file a Form 943-X to correct federal income tax withholding for prior years for nonadministrative errors. In other words, you can’t correct federal income tax actually withheld from an employee in a prior year if you discover that you didn’t withhold the right amount. For example, you can’t correct federal income tax withheld in a prior year because you used the wrong income tax withholding table or you didn’t treat a payment correctly as taxable or nontaxable. Similarly, if you paid federal income tax in a prior year on behalf of your employee rather than deducting it from the employee’s pay (which resulted in additional wages subject to tax), and in a subsequent year you determine that you incorrectly calculated the amount of tax, you can’t correct the federal income tax withholding. However, you must still make any necessary corrections to the amount of wages you reported on Form 943 and Form W-2, Wage and Tax Statement, for a prior year by filing Form 943-X and Form W-2c, Corrected Wage and Tax Statement, respectively.

This is an Image: taxtip.gifThe amount actually withheld is reflected on payroll information or on Form W-2, which can be used by the employee to claim a credit for withholding for individual income tax return purposes.

Correcting Additional Medicare Tax withholding and wages subject to Additional Medicare Tax withholding.

Wages subject to Additional Medicare Tax withholding are reported on Form 943, line 6. Certain errors discovered on a previously filed Form 943 are corrected on Form 943-X, line 10. However, you can't file a Form 943-X to correct the wrong amount of Additional Medicare Tax actually withheld from an employee in a prior year, including any amount you paid on behalf of your employee rather than deducting it from the employee's pay (which resulted in additional wages subject to tax). See the instructions for line 10, later, for more information on the types of errors that can be corrected and how the correction is reported on Form 943-X. For more information about Additional Medicare Tax withholding, see the Instructions for Form 943 or go to IRS.gov/ADMTfaqs.

You may need to attach Schedule R (Form 943) to your Form 943-X.

If you were required to file Schedule R (Form 943), Allocation Schedule for Aggregate Form 943 Filers, when you filed Form 943, you must complete Schedule R (Form 943) when correcting an aggregate Form 943. Schedule R (Form 943) is completed only for those clients and customers who have corrections reported on Form 943-X. Schedule R (Form 943) is filed as an attachment to Form 943-X.

Approved section 3504 agents and certified professional employer organizations (CPEOs) must complete and file Schedule R (Form 943) when filing an aggregate Form 943. Aggregate Forms 943 are filed by agents approved by the IRS under section 3504. To request approval to act as an agent for an employer, the agent files Form 2678 with the IRS. Aggregate Forms 943 are also filed by CPEOs approved by the IRS under section 7705. To become a CPEO, the organization must apply through the IRS Online Registration System at IRS.gov/CPEO. CPEOs file Form 8973, Certified Professional Employer Organization/Customer Reporting Agreement, to notify the IRS that they started or ended a service contract with a customer.

Other third-party payers that file aggregate Forms 943, such as non-certified PEOs, must complete and file Schedule R (Form 943) if they have clients that are claiming the qualified small business payroll tax credit for increasing research activities, the credit for qualified sick and family leave wages, the employee retention credit, and/or the COBRA premium assistance credit, or clients deferring the employer or the employee share of social security tax. If you're an other third-party payer that didn't file Schedule R (Form 943) with Form 943 because you didn't meet these requirements, but are now filing Form 943-X to report these credits or the deferral of the employer or the employee share of social security tax for your clients, then you must now file Schedule R (Form 943) and attach it to Form 943-X.

Use Form 843, Claim for Refund and Request for Abatement, to request a refund or abatement of assessed interest or penalties. Don’t request a refund or abatement of assessed interest or penalties on Form 943 or Form 943-X.

This is an Image: taxtip.gifWe use the terms “correct” and “corrections” on Form 943-X and in these instructions to include interest-free adjustments under sections 6205 and 6413 and claims for refund and abatement under sections 6402, 6414, and 6404. See Rev. Rul. 2009-39 for examples of how the interest-free adjustment and claim for refund rules apply in 10 different situations. You can find Rev. Rul. 2009-39, 2009-52 I.R.B. 951, at IRS.gov/irb/2009-52_IRB#RR-2009-39.

When you discover an error on a previously filed Form 943, you must:

  • Correct that error using Form 943-X;

  • File a separate Form 943-X for each Form 943 that you’re correcting; and

  • Generally, file Form 943-X separately. Don’t file Form 943-X with Form 943. However, if you didn't previously file Form 943 because you mistakenly treated your employees as nonemployees, you may have to file Form 943-X with Form 943. See the instructions for line 40, later.

If you didn’t file a Form 943 for 1 or more years for which you should have filed Form 943, don’t use Form 943-X. Instead, file Form 943 for each of those years. Also, see When Should You File Form 943-X , later. However, if you didn’t file Form(s) 943 because you improperly treated workers as independent contractors or nonemployees and are now reclassifying them as employees, see the instructions for line 40, later.

This is an Image: taxtip.gifUnless otherwise specified in these instructions, an underreported employment tax credit or social security tax deferral should be treated like an overreported tax amount. An overreported employment tax credit or social security tax deferral should be treated like an underreported tax amount. For more information, including which process to select on lines 1 and 2, see Correcting an employment tax credit or social security tax deferral, later.

Report the correction of underreported and overreported tax amounts for the same year on a single Form 943-X, unless you’re requesting a refund or abatement. If you’re requesting a refund or abatement and you’re correcting both underreported and overreported tax amounts, file one Form 943-X correcting the underreported tax amounts only and a second Form 943-X correcting the overreported tax amounts.

You’ll use the adjustment process if you underreported employment taxes and are making a payment, or if you overreported employment taxes and will be applying the credit to Form 943 for the period during which you file Form 943-X. However, see the Caution under Is There a Deadline for Filing Form 943-X, later, if you’re correcting overreported tax amounts during the last 90 days of a period of limitations. You’ll use the claim process if you overreported employment taxes and are requesting a refund or abatement of the overreported tax amount. Follow the chart on page 6 of Form 943-X for help in choosing whether to use the adjustment process or the claim process. Be sure to give us a detailed explanation on line 41 for each correction that you show on Form 943-X.

Continue to report current year adjustments for fractions of cents, third-party sick pay, and group-term life insurance on Form 943, line 10.

You have additional requirements to complete when filing Form 943-X, such as certifying that you filed (or will file) all applicable Forms W-2 and Forms W-2c. For corrections of overreported federal income tax, social security tax, Medicare tax, or Additional Medicare Tax, you must make any certifications that apply to your situation.

This is an Image: caution.gifDon’t use Form 943-X to correct Form CT-1, 941, 941-SS, 944, or 945. Instead, use the “X” form that corresponds to those forms (Form CT-1 X, 941-X, 944-X, or 945-X).

Where Can You Get Help?

For help filing Form 943-X or for questions about federal employment taxes and tax corrections, you can:

  • Go to IRS.gov/EmploymentTaxes and IRS.gov/CorrectingEmploymentTaxes;

  • See Pub. 15 or Pub. 51, Agricultural Employer's Tax Guide; or

See also How Can You Get Forms, Instructions, and Publications From the IRS , later.

This is an Image: taxtip.gifFor tax years beginning after December 31, 2023, Pub. 15 will be used by all employers, including agricultural employers. Pub. 51 will be discontinued, but you may still need to reference the Pub. 51 that was applicable for the tax year that you're correcting

When Should You File Form 943-X?

File Form 943-X when you discover an error on a previously filed Form 943.

However, if your only errors on Form 943 relate to the number of employees (Form 943, line 1) or to federal tax liabilities reported on your Monthly Summary of Federal Tax Liability on Form 943, line 17, or on Form 943-A, Agricultural Employer's Record of Federal Tax Liability, don’t file Form 943-X. For more information about correcting federal tax liabilities reported on your Monthly Summary of Federal Tax Liability on Form 943, line 17, or on Form 943-A, see the Form 943-A instructions.

Due dates.

The due date for filing Form 943-X depends on when you discover an error and if you underreported or overreported tax. If you underreported tax, see Underreported tax , later. For overreported tax amounts, you may choose to either make an interest-free adjustment or file a claim for refund or abatement. If you’re correcting overreported tax amounts, see Overreported tax—Adjustment process and Overreported tax—Claim process , later.

If any due date falls on a Saturday, Sunday, or legal holiday, you may file Form 943-X on the next business day. If we receive Form 943-X after the due date, we will treat Form 943-X as filed on time if the envelope containing Form 943-X is properly addressed, contains sufficient postage, and is postmarked by the U.S. Postal Service on or before the due date, or sent by an IRS-designated private delivery service (PDS) on or before the due date. If you don’t follow these guidelines, we will consider Form 943-X filed when it is actually received. See Pub. 15 for more information on legal holidays. For more information about PDSs, see Where Should You File Form 943-X , later.

Underreported tax.

If you’re correcting underreported tax, you must file Form 943-X by the due date of the return for the return period in which you discovered the error (January 31 of the following year) and pay the amount you owe by the time you file. Doing so will generally ensure that your correction is interest free and not subject to failure-to-pay (FTP) or failure-to-deposit (FTD) penalties. See What About Penalties and Interest , later. For details on how to make a payment, see the instructions for line 25, later.

If Form 943-X is filed late (after the due date of the return for the return period in which you discovered the error), you must attach an amended Form 943-A to Form 943-X. Otherwise, the IRS may assess an “averaged” FTD penalty. See “Averaged” FTD penalty in section 11 of Pub. 15 for more information about “averaged” FTD penalties. The total tax reported on Form 943-A, line M, must match the corrected tax (Form 943, line 13, combined with any correction reported on Form 943-X, line 20) for the year, less any previous abatements and interest-free tax assessments.

Example—You owe tax.

On February 16, 2024, you discovered that you underreported $1,000 of social security and Medicare wages on your 2023 Form 943. File Form 943-X and pay the amount you owe by January 31, 2025, because you discovered the error in 2024 and January 31, 2025, is the due date for that year. If you file Form 943-X before January 31, 2025, pay the amount you owe by the time you file.

This is an Image: caution.gifForm 943-X can’t be used to correct underreported amounts of Additional Medicare Tax unless the amounts were withheld from employee wages.

Overreported tax—Adjustment process.

If you overreported tax and choose to apply the credit to Form 943, file an adjusted return on Form 943-X soon after you discover the error but more than 90 days before the period of limitations on the credit or refund for Form 943 expires. See Is There a Deadline for Filing Form 943-X , later.

This is an Image: caution.gifForm 943-X can’t be used to correct overreported amounts of Additional Medicare Tax unless the amounts weren’t withheld from employee wages.

Example—You want your credit applied to Form 943.

You filed your 2023 Form 943 on January 31, 2024, and payments were timely made. On May 6, 2024, you discover that you overreported tax on your 2023 Form 943. You file Form 943-X on June 7, 2024, and check the box on line 1 to indicate you want to use the adjustment process. The IRS treats your credit as a tax deposit made on January 1, 2024. When you file your 2024 Form 943, include the amount from Form 943-X, line 25, on the “Total deposits” line of your 2024 Form 943.

Overreported tax—Claim process.

If you overreported tax on Form 943, you may choose to file a claim for refund or abatement on Form 943-X any time before the period of limitations on the credit or refund expires. If you also need to correct any underreported tax amounts, you must file another Form 943-X reporting only corrections to the underreported tax amounts. See Is There a Deadline for Filing Form 943-X , later.

This is an Image: caution.gif You may not file a refund claim to correct federal income tax or Additional Medicare Tax actually withheld from employees.

Is There a Deadline for Filing Form 943-X?

Generally, you may correct overreported taxes on a previously filed Form 943 if you file Form 943-X within 3 years of the date Form 943 was filed or 2 years from the date you paid the tax reported on Form 943, whichever is later. You may correct underreported taxes on a previously filed Form 943 if you file Form 943-X within 3 years of the date the Form 943 was filed. We call each of these time frames a period of limitations. For purposes of the period of limitations, Form 943 is considered filed on April 15 of the succeeding calendar year if filed before that date.

Example.

You filed your 2020 Form 943 on January 28, 2021, and payments were timely made. The IRS treats the return as if it were filed on April 15, 2021. On January 24, 2024, you discovered that you overreported social security and Medicare wages on that form by $350. To correct the error, you must file Form 943-X by April 15, 2024, and use the claim process.

This is an Image: caution.gifIf you file Form 943-X to correct overreported tax amounts in the last 90 days of a period of limitations, you must use the claim process. You can’t use the adjustment process. If you’re also correcting underreported tax amounts, you must file another Form 943-X to correct the underreported tax amounts using the adjustment process and pay any tax due.

How Should You Complete Form 943-X?

Use a Separate Form 943-X for Each Year You’re Correcting

Use a separate Form 943-X for each Form 943 that you’re correcting. For example, if you found errors on your Forms 943 for 2022 and 2023, file one Form 943-X to correct the 2022 Form 943, and file a second Form 943-X to correct the 2023 Form 943.

Employer Identification Number (EIN), Name, and Address

Enter your EIN, name, and address in the spaces provided. Also enter your name and EIN on the top of pages 2, 3, 4, and 5, and on any attachments. If your address has changed since you filed your Form 943, enter the corrected information and the IRS will update your address of record. Be sure to write your name, EIN, “Form 943-X,” and the calendar year you’re correcting on the top of any attachments.

Return You’re Correcting

Enter the calendar year of the Form 943 you’re correcting in the box at the top of page 1. Enter the same calendar year on pages 2, 3, 4, and 5, and on any attachments.

Enter the Date You Discovered Errors

You must enter the date you discovered errors. You discover an error when you have enough information to be able to correct the error. If you’re reporting several errors you discovered at different times, enter the earliest date you discovered an error here. Report any subsequent dates and related errors on line 41.

Must You Make an Entry on Each Line?

You must provide all of the information requested at the top of Form 943-X, page 1. You must check one box (but not both) in Part 1. In Part 2, you must check the box on line 3 and any applicable boxes on lines 4 and 5. In Part 3, if any line doesn't apply, leave it blank. Complete Parts 4 and 5 as instructed.

How Should You Report Negative Amounts?

Form 943-X uses negative numbers to show reductions in tax (credits) and positive numbers to show additional tax (amounts you owe).

When reporting a negative amount in columns 3 and 4, use a minus sign instead of parentheses. For example, enter “-10.59” instead of “(10.59).” However, if you’re completing the return on your computer and your software only allows you to use parentheses to report negative amounts, you may use them.

How Should You Make Entries on Form 943-X?

You can help the IRS process Form 943-X timely and accurately if you follow these guidelines.

  • Type or print your entries.

  • Use Courier font (if possible) for all typed or computer-generated entries.

  • Omit dollar signs. You may use commas and decimal points, if desired. Enter dollar amounts to the left of any preprinted decimal point and cents to the right of it.

  • Always show an amount for cents, even if it is zero. Don't round entries to whole dollars.

  • Complete all five pages and sign Form 943-X on page 5.

  • Staple multiple sheets in the upper-left corner.

What About Penalties and Interest?

Generally, your correction of an underreported tax amount won’t be subject to an FTP penalty, an FTD penalty, or interest if you:

  • File on time (by the due date of Form 943 for the year in which you discover the error),

  • Pay the amount shown on line 25 by the time you file Form 943-X,

  • Enter the date you discovered the error, and

  • Explain in detail the grounds and facts relied upon to support the correction.

No correction will be eligible for interest-free treatment if any of the following apply.

  • The amounts underreported relate to an issue that was raised in an examination of a prior period.

  • You knowingly underreported your employment tax liability.

  • You received a notice and demand for payment.

  • You received a notice of determination under section 7436.

If you receive a notice about a penalty after you file this return, reply to the notice with an explanation and we will determine if you meet reasonable-cause criteria. Don’t attach an explanation when you file your return.

Overview of the Process

To correct a previously filed Form 943, use Form 943-X to file either an adjusted employment tax return or a claim for refund or abatement. The adjustment process and the claim process are outlined below.

If you underreported the tax.

If you underreported the tax on a previously filed Form 943, check the box on line 1 and pay any additional amount you owe by the time you file Form 943-X. For details on how to make a payment, see the instructions for line 25, later.

Example—You underreported employment taxes.

On June 18, 2024, you discovered an error that results in additional tax on your 2023 Form 943. File Form 943-X by January 31, 2025, and pay the amount you owe by the time you file. See When Should You File Form 943-X , earlier. Don’t attach Form 943-X to your 2024 Form 943.

If you overreported the tax.

If you overreported the tax on a previously filed Form 943, choose one of the following options.

  • Use the adjustment process. Check the box on line 1 to apply any credit (negative amount) from line 25 to Form 943 for the year during which you file Form 943-X.

  • Use the claim process. Check the box on line 2 to file a claim on Form 943-X requesting a refund or abatement of the amount shown on line 25.

This is an Image: taxtip.gifTo ensure that the IRS has enough time to process a credit for an overreporting tax adjustment in the year during which you file Form 943-X, you’re encouraged to file Form 943-X correcting the overreported tax amount in the first 11 months of a year. For example, if you discover an overreported tax amount in December, you may want to file Form 943-X during the first 11 months of the next year. However, there must be 90 days remaining on the period of limitations when you file Form 943-X. See the Caution under Is There a Deadline for Filing Form 943-X, earlier. This should ensure that the IRS will have enough time to process Form 943-X so the credit will be posted before you file Form 943, thus avoiding an erroneous balance due notice from the IRS. See the example below.

Example—You want your overreported tax applied as a credit on Form 943.

On December 20, 2024, you discover you overreported your tax on your 2023 Form 943 and want to choose the adjustment process. To allow the IRS enough time to process the credit, you file Form 943-X on January 3, 2025, and take the credit on your 2025 Form 943.

Specific Instructions:

Part 1: Select ONLY One Process

Because Form 943-X may be used to file either an adjusted employment tax return or a claim for refund or abatement, you must check one box on either line 1 or line 2. Don’t check both boxes.

Correcting an employment tax credit or social security tax deferral.

For lines 1 and 2, if you underreported an employment tax credit or the amount of social security tax deferred, treat it like you overreported a tax amount. If you overreported an employment tax credit or the amount of social security tax deferred, treat it like you underreported a tax amount. If you're filing Form 943-X to adjust only an employment tax credit and/or the amount of social security tax deferred and you're not correcting any overreported taxes on Form 943-X, lines 6–11, skip lines 4 and 5.

1. Adjusted Employment Tax Return

Check the box on line 1 if you’re correcting underreported tax amounts or overreported tax amounts and you would like to use the adjustment process to correct the errors.

If you’re correcting both underreported tax amounts and overreported tax amounts on this form, you must check this box. If you check this box, any negative amount shown on line 25 will be applied as a credit (tax deposit) to your Form 943 for the year in which you’re filing this form. See Example—You want your overreported tax applied as a credit to Form 943 , earlier.

This is an Image: caution.gifForm 943-X can't be used to correct overreported amounts of Additional Medicare Tax unless the amounts weren’t withheld from employee wages.

If you owe tax.

Pay the amount shown on line 25 by the time you file Form 943-X. Generally, you won’t be charged interest if you file on time, pay on time, enter the date you discovered the error, and explain the correction on line 41.

If you have a credit.

You overreported employment taxes (you have a negative amount on line 25) and want the IRS to apply the credit on Form 943 for the period during which you filed Form 943-X. The IRS will apply your credit on the first day of the Form 943 year during which you filed Form 943-X. However, the credit you show on Form 943-X, line 25, may not be fully available on your Form 943 if the IRS corrects it during processing or you owe other taxes, penalties, or interest. The IRS will notify you if your claimed credit changes or if the amount available as a credit on Form 943 was reduced because of unpaid taxes, penalties, or interest.

This is an Image: caution.gifDon’t check the box on line 1 if you’re correcting overreported tax amounts and the period of limitations on credit or refund for Form 943 will expire within 90 days of the date you file Form 943-X. See Is There a Deadline for Filing Form 943-X, earlier.

2. Claim

Check the box on line 2 to use the claim process if you’re correcting overreported tax amounts only and you’re claiming a refund or abatement for the negative amount (credit) shown on line 25. Don’t check this box if you’re correcting any underreported tax amounts on this form.

You must check the box on line 2 if you have a credit (a negative amount on line 25) and the period of limitations on credit or refund for Form 943 will expire within 90 days of the date you file Form 943-X. See Is There a Deadline for Filing Form 943-X , earlier.

The IRS usually processes claims shortly after they are filed. The IRS will notify you if your claim is denied, accepted as filed, or selected to be examined. See Pub. 556, Examination of Returns, Appeal Rights, and Claims for Refund, for more information.

Unless the IRS corrects Form 943-X during processing or you owe other taxes, penalties, or interest, the IRS will refund the amount shown on line 25, plus any interest that applies.

This is an Image: caution.gifYou may not file a refund claim to correct federal income tax or Additional Medicare Tax actually withheld from employees.

Part 2: Complete the Certifications

You must complete all certifications that apply by checking the appropriate boxes. If all of your corrections relate to underreported tax amounts, complete line 3 only; skip lines 4 and 5 and go to Part 3. If your corrections relate to overreported tax amounts, other than corrections related to underreported employment tax credits and social security tax deferrals, you have a duty to ensure that your employees' rights to recover overpaid employee social security and Medicare taxes that you withheld are protected. The certifications on lines 4 and 5 address the requirement to:

  • Repay or reimburse your employees for the overcollection of employee social security and Medicare taxes, or

  • Obtain consents from your employees to file a claim on their behalf. See Rev. Proc. 2017-28 for guidance on the requirements for both a request for employee consent and for the employee consent.

3. Filing Forms W-2 or Forms W-2c

Check the box on line 3 to certify that you filed or will file Forms W-2 or Forms W-2c with the Social Security Administration (SSA), as required, showing your employees' correct wage and tax amounts. See the General Instructions for Forms W-2 and W-3 for detailed information about filing requirements. Unless otherwise noted, references on Form 943-X and throughout these instructions to Form W-2 include Forms W-2AS, W-2CM, W-2GU, W-2VI, and 499R-2/W-2PR; references to Form W-2c include Form 499R-2c/W-2cPR; references to Form W-3 include Form W-3SS and Form W-3PR; and references to Form W-3c include Form W-3C (PR).

You must check the box on line 3 to certify that you filed Forms W-2 or Forms W-2c even if your corrections on Form 943-X don’t change amounts shown on those forms. For example, if your only correction to Form 943 involves misstated tax adjustments, which don't impact the amounts reported on your employee's Form W-2 (see the instructions for line 12, later), check the box on line 3 to certify that you already filed all required Forms W-2 and W-2c with the SSA. In this situation, you're certifying that you don't need to file Form W-2c because you already filed a correct Form W-2.

4. Certifying Overreporting Adjustments

If you overreported federal income tax, social security tax, Medicare tax, or Additional Medicare Tax and checked the box on line 1, check the appropriate box on line 4. You may need to check more than one box. If you obtained written statements from some employees but you couldn’t locate employees or secure the statements of the remaining employees, check all applicable boxes. Provide a summary on line 41 of the amount of the corrections for the employees who provided written statements and for those who didn’t.

This is an Image: caution.gifYou may not use Form 943-X to correct overreported amounts of Additional Medicare Tax unless the amounts weren’t withheld from employee wages.

4a.

Check the box on line 4a if your overreported amount includes each affected employee share of overcollected taxes. You’re certifying that you repaid or reimbursed the employee share of prior year taxes and you received written statements from the employees stating that they didn’t and won’t receive a refund or credit for the prior year taxes. Don’t send these statements to the IRS. Keep them for your records. Generally, all employment tax records must be kept for at least 4 years. Records related to qualified sick leave wages and qualified family leave wages for leave taken after March 31, 2021, and before October 1, 2021, and records related to qualified wages for the employee retention credit paid after June 30, 2021, should be kept for at least 6 years. Copies must be submitted to the IRS if requested.

4b.

Check the box on line 4b to certify that your overreported amount is only for the employer share of taxes on those employees who you were unable to find or who didn’t give you a statement described on line 4a.

4c.

Check the box on line 4c to certify that your overreported amount is only for federal income tax, social security tax, Medicare tax, or Additional Medicare Tax that you didn’t withhold from your employees.

5. Certifying Claims

If you’re filing a claim for refund or abatement of overreported federal income tax, social security tax, Medicare tax, or Additional Medicare Tax and checked the box on line 2, check the appropriate box on line 5. You may need to check more than one box. If you obtained written statements or consents from some employees but you couldn’t locate employees or secure the statements of the remaining employees, check all applicable boxes. Provide a summary on line 41 of the amount of the corrections for the employees who provided statements or consents and for those who didn’t.

This is an Image: caution.gifYou may not file a refund claim to correct the incorrect amount of federal income tax or Additional Medicare Tax actually withheld from employees. If you request their consent to file a claim for social security tax or Medicare tax, you must tell your employees that you can't claim a refund of any Additional Medicare Tax on their behalf. See Rev. Proc. 2017-28 for sample language to use in your request.

5a.

Check the box on line 5a if your overreported tax includes each affected employee share of prior year social security and Medicare taxes. You’re certifying that you repaid or reimbursed to the employees their share of prior year social security and Medicare taxes and you received written statements from those employees stating that they didn’t and won’t receive a refund or credit for the prior year taxes. Don't send these statements to the IRS. Keep them for your records. Generally, all employment tax records must be kept for at least 4 years. Records related to qualified sick leave wages and qualified family leave wages for leave taken after March 31, 2021, and before October 1, 2021, and records related to qualified wages for the employee retention credit paid after June 30, 2021, should be kept for at least 6 years. Copies must be submitted to the IRS if requested.

5b.

Check the box on line 5b if your overreported tax includes each affected employee share of prior year social security and Medicare taxes and you haven’t yet repaid or reimbursed the employee share of taxes. You’re certifying that you received consent from each affected employee to file a claim on the employee share of those taxes and you received written statements from those employees stating that they didn’t and won’t receive a refund or credit for the prior year taxes.

An employee consent must:

  • Contain the name, address, and social security number (or truncated taxpayer identification number, when appropriate) of the employee;

  • Contain the name, address, and EIN of the employer;

  • Contain the tax period(s), the type of tax, and the amount of tax for which the consent is provided;

  • Affirmatively state that the employee authorizes the employer to claim a refund for the overpayment of the employee share of tax;

  • Include the employee's written statement certifying that the employee hasn't made any previous claims (or the claims were rejected) and won't make any future claims for refund or credit of the amount of the overcollection;

  • Identify the basis of the claim; and

  • Be dated and contain the employee's signature under penalties of perjury. The penalties of perjury statement should be located immediately above the required signature.

Don’t send these statements and consents to the IRS. Keep them for your records. Generally, all employment tax records must be kept for at least 4 years. Records related to qualified sick leave wages and qualified family leave wages for leave taken after March 31, 2021, and before October 1, 2021, and records related to qualified wages for the employee retention credit paid after June 30, 2021, should be kept for at least 6 years. Copies must be submitted to the IRS if requested.

In certain situations, you may not have repaid or reimbursed your employees or obtained their consents before filing a claim, such as in cases where the period of limitations on credit or refund is about to expire. In those situations, file Form 943-X but don’t check a box on line 5. Tell us on line 41 that you haven’t repaid or reimbursed employees or obtained consents at the time you file the claim. However, you must repay or reimburse your employees and certify that you have done so before the IRS can allow the claim.

5c.

Check the box on line 5c to certify that your overreported tax is only for the employer share of social security and Medicare taxes. This applies when affected employees didn’t give you consent to file a claim for refund for the employee share of social security and Medicare taxes, they couldn’t be found, or they didn’t give you a statement described on line 5b.

5d.

Check the box on line 5d to certify that your overreported amount is only for federal income tax, social security tax, Medicare tax, or Additional Medicare Tax that you didn’t withhold from your employees.

Part 3: Enter the Corrections for the Calendar Year You’re Correcting

What Amounts Should You Report in Part 3?

On lines 6–11, columns 1 and 2, for each line you’re correcting, show amounts for all of your employees, not just for those employees whose amounts you’re correcting.

If a correction that you report in column 4 includes both underreported and overreported amounts (see the instructions for line 39, later), give us details for each error on line 41.

Because special circumstances apply for lines 12–19, 21–24c, and 26–38, read the instructions for each line carefully before entering amounts in the columns.

If any line doesn't apply to you, leave it blank.

This is an Image: caution.gifIf you previously adjusted or amended Form 943 using Form 943-X or because of an IRS examination change, show amounts in column 2 that include those previously reported corrections.

6. Wages Subject to Social Security Tax

This is an Image: taxtip.gifQualified sick leave wages and qualified family leave wages for leave taken after March 31, 2021, and before October 1, 2021, were included on Form 943, line 2, and can be adjusted only on Form 943-X, line 6.

If you’re correcting the taxable social security wages you reported on Form 943, line 2, enter the total corrected amount for all employees in column 1. In column 2, enter the amount you originally reported or as previously corrected. In column 3, enter the difference between columns 1 and 2.

If you or the IRS previously corrected the amount reported on Form 943, line 2, enter in column 2 the amount after any previous corrections.

line 6 (column 1)    
- line 6 (column 2)    
line 6 (column 3)   If the amount in column 2 is larger than the amount in column 1, use a minus sign in column 3.

Multiply the amount in column 3 by 0.124 (12.4% tax rate) and enter that result in column 4.

line 6 (column 3)    
x 0.124    
line 6 (column 4)   If the amount in column 3 used a minus sign, also use a minus sign in column 4.

Note.

If you checked the box on Form 943-X, line 4b or line 5c, because you’re correcting only the employer share of tax on a decrease to social security wages, use 0.062 (6.2%) when multiplying the amount shown in column 3. If you’re correcting both shares of tax for some employees and only the employer share for other employees, enter the properly calculated amount in column 4. Be sure to show your calculations on line 41.

Example—Social security wages decreased.

You reported $9,000 as social security wages on your 2023 Form 943, line 2. In December of 2024, you discover that you included $2,000 in social security wages for one of your employees twice. To correct the error, figure the difference on Form 943-X as shown below.

Column 1 (corrected amount) 7,000.00  
Column 2 (Form 943, line 2) - 9,000.00  
Column 3 (difference) -2,000.00  

Use the difference in column 3 to determine your tax correction.

Column 3 (difference) -2,000.00  
Tax rate (12.4%) x 0.124  
Column 4 (tax correction) -248.00  

Be sure to explain the reasons for this correction on line 41.

7. Qualified Sick Leave Wages (For Leave Taken After March 31, 2020, and Before April 1, 2021)

This is an Image: taxtip.gifAdjustments to the social security tax on qualified sick leave wages and qualified family leave wages for leave taken after March 31, 2020, and before April 1, 2021, are reported on Form 943‐X, lines 7 and 8, respectively. Adjustments to the nonrefundable portion of the credit for qualified sick and family leave wages for leave taken after March 31, 2020, and before April 1, 2021, are reported on Form 943‐X, line 14, and adjustments to the refundable portion of the credit are reported on Form 943‐X, line 23. Adjustments to qualified health plan expenses allocable to qualified sick leave wages and to qualified family leave wages for leave taken after March 31, 2020, and before April 1, 2021, are reported on Form 943‐X, lines 26 and 27, respectively. For corrections to a 2020 Form 943, the credit for qualified sick and family leave wages is only available for wages paid with respect to leave taken after March 31, 2020, and before January 1, 2021. If you claimed the credit for qualified sick and family leave wages for leave taken after March 31, 2020, and before April 1, 2021, on your original Form 943, and you make any corrections on Form 943‐X to amounts used to figure this credit, you’ll need to refigure the amount of this credit using Worksheet 1. You’ll also use this worksheet to figure this credit if you're claiming the credit for the first time on Form 943-X. For more information about the credit for qualified sick and family leave wages, go to IRS.gov/PLC.

Qualified sick leave wages paid with respect to leave taken after March 31, 2020, and before April 1, 2021, aren't subject to the employer share of social security tax; therefore, the tax rate on these wages is 6.2% (0.062). For more information about qualified sick leave wages, see Definition of qualified sick and family leave wages for leave taken after March 31, 2020, and before April 1, 2021 , later, and go to IRS.gov/PLC. If you're correcting the qualified sick leave wages you reported on Form 943, line 2a, enter the total corrected amount in column 1. In column 2, enter the amount you originally reported or as previously corrected. In column 3, enter the difference between columns 1 and 2.

line 7 (column 1)    
- line 7 (column 2)    
line 7 (column 3)   If the amount in column 2 is larger than the amount in column 1, use a minus sign in column 3.

Multiply the amount in column 3 by 0.062 and enter that result in column 4.

line 7 (column 3)    
x 0.062    
line 7 (column 4)   If the amount in column 3 used a minus sign, also use a minus sign in column 4.

Note.

If you erroneously reported qualified sick leave wages for leave taken after March 31, 2020, and before April 1, 2021, on Form 943, line 2, instead of on line 2a, you’ll need to make a correction on Form 943-X, lines 6 and 7, and enter the properly calculated amount in column 4 for each line.

Example—Qualified sick leave wages increased.

You paid $2,000 of qualified sick leave wages to only one of your employees on March 26, 2021. In March 2024, you discover that you only reported $1,000 of qualified sick leave wages on your 2021 Form 943. To correct the error, figure the difference on Form 943‐X as shown below.

Column 1 (corrected amount) 2,000.00  
Column 2 (Form 943, line 2a) - 1,000.00  
Column 3 (difference) 1,000.00  

Use the difference in column 3 to determine your tax correction.

Column 3 (difference) 1,000.00  
Tax rate (6.2%) x 0.062  
Column 4 (tax correction) 62.00  

Be sure to explain the reasons for this correction on line 41.

8. Qualified Family Leave Wages (For Leave Taken After March 31, 2020, and Before April 1, 2021)

Qualified family leave wages paid with respect to leave taken after March 31, 2020, and before April 1, 2021, aren't subject to the employer share of social security tax; therefore, the tax rate on these wages is 6.2% (0.062). For more information about qualified family leave wages, see Definition of qualified sick and family leave wages for leave taken after March 31, 2020, and before April 1, 2021 , later, and go to IRS.gov/PLC. If you're correcting the qualified family leave wages you reported on Form 943, line 2b, enter the total corrected amount in column 1. In column 2, enter the amount you originally reported or as previously corrected. In column 3, enter the difference between columns 1 and 2.

line 8 (column 1)    
- line 8 (column 2)    
line 8 (column 3)   If the amount in column 2 is larger than the amount in column 1, use a minus sign in column 3.

Multiply the amount in column 3 by 0.062 and enter that result in column 4.

line 8 (column 3)    
x 0.062    
line 8 (column 4)   If the amount in column 3 used a minus sign, also use a minus sign in column 4.

Note.

If you erroneously reported qualified family leave wages for leave taken after March 31, 2020, and before April 1, 2021, on Form 943, line 2, instead of on line 2b, you’ll need to make a correction on Form 943-X, lines 6 and 8, and enter the properly calculated amount in column 4 for each line.

Example—Qualified family leave wages decreased.

You paid $1,000 of qualified family leave wages to only one of your employees on March 26, 2021. In March 2024, you discover that you erroneously reported $3,000 of qualified family leave wages on your 2021 Form 943. To correct the error, figure the difference on Form 943‐X as shown below.

Column 1 (corrected amount) 1,000.00  
Column 2 (Form 943, line 2b) - 3,000.00  
Column 3 (difference) -2,000.00  

Use the difference in column 3 to determine your tax correction.

Column 3 (difference) -2,000.00  
Tax rate (6.2%) x 0.062  
Column 4 (tax correction) -124.00  

Be sure to explain the reasons for this correction on line 41.

9. Wages Subject to Medicare Tax

If you’re correcting the taxable Medicare wages you reported on Form 943, line 4, enter the total corrected amount in column 1. In column 2, enter the amount you originally reported or as previously corrected. In column 3, enter the difference between columns 1 and 2.

line 9 (column 1)      
- line 9 (column 2)      
line 9 (column 3)   If the amount in column 2 is larger than the amount in column 1, use a minus sign in column 3.

Multiply the amount in column 3 by 0.029 (2.9% tax rate) and enter that result in column 4.

line 9 (column 3)      
x 0.029      
line 9 (column 4)   If the amount in column 3 used a minus sign, also use a minus sign in column 4.

Note.

If you checked the box on Form 943-X, line 4b or line 5c, because you’re correcting only the employer share of tax on a decrease to Medicare wages, use 0.0145 (1.45%) when multiplying the amount in column 3. If you’re correcting both shares of tax for some employees and only the employer share for other employees, enter the properly calculated amount in column 4. Be sure to explain your calculations on line 41.

Example—Medicare wages decreased.

Following Example—Social security wages decreased in the instructions for line 6, the wages that you counted twice were also taxable Medicare wages. To correct the error, figure the difference on Form 943-X as shown next.

Column 1 (corrected amount) 7,000.00  
Column 2 (Form 943, line 4) - 9,000.00  
Column 3 (difference) -2,000.00  

Use the difference in column 3 to determine your tax correction.

Column 3 (difference) -2,000.00  
Tax rate (2.9%) x 0.029  
Column 4 (tax correction) -58.00  

Be sure to explain the reasons for this correction on line 41.

10. Wages Subject to Additional Medicare Tax Withholding

You may use Form 943-X to correct errors to Additional Medicare Tax withholding for prior years if the amount reported on Form 943, line 7, isn’t the amount you actually withheld. This type of error is an administrative error. The administrative error adjustment corrects the amount reported on Form 943 to agree with the amount actually withheld from employees.

You may also correct errors to Additional Medicare Tax withholding for prior years if section 3509 rates apply. If section 3509 rates apply, see the instructions for lines 16–19, later.

If a prior year error was a nonadministrative error, you may correct only the wages subject to Additional Medicare Tax withholding that were originally reported on Form 943, line 6, or previously corrected on Form 943-X. You can’t correct the tax reported on Form 943, line 7.

Prior year administrative errors.

If you’re correcting the wages subject to Additional Medicare Tax withholding that you reported on Form 943, line 6, enter the total corrected amount in column 1. In column 2, enter the amount you originally reported or as previously corrected. In column 3, enter the difference between columns 1 and 2.

line 10 (column 1)      
- line 10 (column 2)      
line 10 (column 3)   If the amount in column 2 is larger than the amount in column 1, use a minus sign in column 3.

Multiply the amount in column 3 by 0.009 (0.9% tax rate) and enter that result in column 4.

line 10 (column 3)      
x 0.009      
line 10 (column 4)   If the amount in column 3 used a minus sign, also use a minus sign in column 4.

Example—Prior year administrative error (incorrectly reported amount of Additional Medicare Tax actually withheld).

Nathan Black's wages exceeded the $200,000 withholding threshold for Additional Medicare Tax in November 2023. The total wages paid to Nathan for 2023 were $230,000. You withheld $270 ($30,000 x 0.009) from Nathan's wages. However, on your 2023 Form 943, you mistakenly reported $3,000 on line 6, and Additional Medicare Tax withheld of $27 on line 7. You discover the error on March 13, 2024. This is an example of an administrative error that may be corrected in a later calendar year because the amount actually withheld isn’t the amount reported on your 2023 Form 943. Use Form 943-X, line 10, to correct the error as shown below.

Column 1 (corrected amount) 30,000.00  
Column 2 (Form 943, line 6) - 3,000.00  
Column 3 (difference) 27,000.00  

Use the difference in column 3 to determine your tax correction.

Column 3 (difference) 27,000.00  
Tax rate (0.9%) x 0.009  
Column 4 (tax correction) 243.00  

Be sure to explain the reasons for this correction on line 41.

Prior year nonadministrative errors.

You may correct only the taxable wages subject to Additional Medicare Tax withholding that you reported on Form 943, line 6. Enter the total corrected amount in column 1. In column 2, enter the amount you originally reported or as previously corrected. In column 3, enter the difference between columns 1 and 2.

line 10 (column 1)      
- line 10 (column 2)      
line 10 (column 3)   If the amount in column 2 is larger than the amount in column 1, use a minus sign in column 3.

Don’t multiply the amount in column 3 by 0.009 (0.9% tax rate). Leave column 4 blank and explain the reasons for this correction on line 41.

Example—Prior year nonadministrative error (failure to withhold Additional Medicare Tax when required).

Leah Green's wages exceeded the $200,000 withholding threshold for Additional Medicare Tax in December 2023. The total wages paid to Leah for 2023 were $220,000. You were required to withhold $180 ($20,000 x 0.009) but you withheld nothing and didn’t report an amount on line 6 or line 7 of your 2023 Form 943. You discover the error on March 13, 2024. File Form 943-X to correct the wages subject to Additional Medicare Tax withholding for your 2023 Form 943, but you may not correct the Additional Medicare Tax withheld (column 4) because the error involves a previous year and the amount previously reported for the employee represents the actual amount withheld from the employee during 2023.

Combination of prior year administrative and nonadministrative errors.

If you’re reporting both administrative errors and nonadministrative errors for the same prior year, enter the total corrected amount in column 1. In column 2, enter the amount you originally reported or as previously corrected. In column 3, enter the difference between columns 1 and 2. However, multiply only the amount of wages reported in column 3 that are related to administrative errors by 0.009 (0.9% tax rate). Don’t multiply any wages reported in column 3 that are related to nonadministrative errors by 0.009 (0.9% tax rate). Use line 41 to explain in detail your corrections. The explanation must include the reasons for the corrections and a breakdown of the amount reported in column 3 into the amounts related to administrative errors and nonadministrative errors.

Example—Combination of prior year administrative and nonadministrative errors.

Nathan Black's wages exceeded the $200,000 withholding threshold for Additional Medicare Tax in November 2023. The total wages paid to Nathan for 2023 were $230,000. You withheld $270 ($30,000 x 0.009) from Nathan's wages. However, on your 2023 Form 943, you mistakenly reported $3,000 on line 6, and Additional Medicare Tax withheld of $27 on line 7. The difference in wages subject to Additional Medicare Tax related to this administrative error is $27,000 ($30,000 − $3,000).

Leah Green's wages exceeded the $200,000 withholding threshold for Additional Medicare Tax in December 2023. The total wages paid to Leah for 2023 were $220,000. You were required to withhold $180 ($20,000 x 0.009) but you withheld nothing and didn’t report Leah’s $20,000 in wages subject to Additional Medicare Tax withholding on line 6 of your 2023 Form 943.

You discover both errors on March 13, 2024. Use Form 943-X, line 10, to correct the errors as shown below.

Column 1 (corrected amount) 50,000.00  
Column 2 (Form 943, line 6) - 3,000.00  
Column 3 (difference) 47,000.00  

Determine the portion of wages reported in column 3 that is related to the administrative error ($47,000 − $20,000 (nonadministrative error) = $27,000 (administrative error)). Multiply this portion of column 3 by 0.009 (0.9% tax rate) to determine your tax correction.

Difference related to administrative error 27,000.00  
Tax rate (0.9%) x 0.009  
Column 4 (tax correction) 243.00  

Be sure to explain the reasons for these corrections on line 41. You must also report that $20,000 of the amount shown in column 3 was related to the correction of a prior year nonadministrative error and $27,000 of the amount shown in column 3 was related to the correction of an administrative error.

11. Federal Income Tax Withheld

If you’re correcting the federal income tax withheld from wages you reported on Form 943, line 8, enter the total corrected amount in column 1. In column 2, enter the amount you originally reported or as previously corrected. In column 3, enter the difference between columns 1 and 2.

line 11 (column 1)    
- line 11 (column 2)    
line 11 (column 3)   If the amount in column 2 is larger than the amount in column 1, use a minus sign in column 3.

Copy the amount in column 3 to column 4. Include any minus sign shown in column 3.

This is an Image: caution.gifGenerally, you may only correct administrative errors to federal income tax withholding (that is, errors in which the amount reported on Form 943, line 8, isn't the amount you actually withheld from an employee's wages) and errors for which section 3509 rates apply. Only transposition or math errors involving the inaccurate reporting of the amount withheld are “administrative errors.” The administrative error adjustment corrects the amount reported on Form 943 to agree with the amount actually withheld from employees. See section 2 of Pub. 15 for more information about corrections during the calendar year and about administrative errors. If section 3509 rates apply, see the instructions for lines 16–19, later.

This is an Image: caution.gifYou can't file a Form 943-X to correct federal income tax withholding for prior years for nonadministrative errors. In other words, you can't correct federal income tax actually withheld from an employee in a prior year if you discover that you didn't withhold the right amount. For example, you can't correct federal income tax withheld in a prior year because you used the wrong income tax withholding table or you didn't treat a payment correctly as taxable or nontaxable. Similarly, if you paid federal income tax in a prior year on behalf of your employee rather than deducting it from the employee's pay (which resulted in additional wages subject to tax), and in a subsequent year you determine that you incorrectly calculated the amount of tax, you can't correct the federal income tax withholding.

Example—Prior year nonadministrative error (failure to withhold federal income tax when required).

You were required to withhold $400 of federal income tax from an employee bonus that was paid in December of 2023 but you withheld nothing. You discovered the error on March 15, 2024. You can’t file Form 943-X to correct federal income tax withheld reported on your 2023 Form 943 because the error involves a previous year and the amount previously reported for the employee represents the actual amount withheld from the employee during 2023.

Example—Prior year administrative error (incorrectly reported amount of federal income tax actually withheld).

You had three employees. In 2023, you withheld $1,000 of federal income tax from Nathan Black, $2,000 from Leah Green, and $6,000 from Becky Lee. The total amount of federal income tax you withheld was $9,000. You mistakenly reported $6,000 on line 8 of your 2023 Form 943. You discovered the error on March 15, 2024. This is an example of an administrative error that may be corrected in a later calendar year because the amount actually withheld from employees' wages isn’t the amount reported on Form 943. Use Form 943-X to correct the error. Enter $9,000 in column 1 and $6,000 in column 2. Subtract the amount in column 2 from the amount in column 1.

Column 1 (corrected amount) 9,000.00  
Column 2 (Form 943, line 8) - 6,000.00  
Column 3 (difference) 3,000.00  

Report the $3,000.00 as a tax correction in column 4.

Be sure to explain the reasons for this correction on line 41.

Example—Nonadministrative error reporting income tax because of repayment of wages paid in prior year.

You prepaid Jack Brown $4,000 of wages for 2 months of work in September 2023. You withheld $400 of federal income tax at the time you paid Jack. These amounts were reported on your 2023 Form 943. Jack left employment in October 2023 (after only 1 month of service). In February 2024, Jack repaid $2,000 to you for the 1 month he didn't work. You can't file Form 943-X to reduce the federal income tax withheld because you actually withheld the federal income tax from wages. You also can't file Form 943-X to reduce wages because the wages were income to Jack for the prior year. These amounts were correctly reported on Form 943.

12. Tax Adjustments

This is an Image: taxtip.gifFor purposes of these instructions, all references to “sick pay” mean ordinary sick pay, not “qualified sick leave wages.”

Don’t enter an amount on line 12 unless you need to correct any adjustments reported on Form 943, line 10. Amounts reported on line 12 reflect corrections of amounts misstated on Form 943, line 10. See Example—Third-party sick pay underreported , later.

Enter in column 1 the total corrected amount for Form 943, line 10. Enter in column 2 the total originally reported or previously corrected amount from Form 943, line 10. In column 3, enter the difference between columns 1 and 2.

line 12 (column 1)    
- line 12 (column 2)    
line 12 (column 3)    

This is an Image: taxtip.gifYou may need to report negative numbers in any column. Make sure that the difference you enter in column 3 accurately represents the change to adjustments originally reported or previously corrected on Form 943, line 10.

Copy the amount in column 3 to column 4. Include any minus sign shown in column 3.

On line 41, describe what you misreported on Form 943. Tell us if your adjustment is for fractions of cents, third-party sick pay, or group-term life insurance.

Example—Third-party sick pay underreported.

You reported $6,900 (shown as “-6,900.00”) as a third-party sick pay adjustment (reduction to tax) on your 2023 Form 943, line 10. Your third-party sick pay adjustment should have been $9,600 (shown as “-9,600.00”) because your third-party sick pay payer withheld that amount of social security and Medicare taxes from your employees. You discover the error in April of 2024. To correct the error, figure the difference on Form 943-X as shown below.

Column 1 (corrected amount) -9,600.00  
Column 2 (Form 943, line 10) - (6,900.00)  
Column 3 (difference) -2,700.00  

Here is how you would enter the numbers on Form 943-X.

Column 1 Column 2 Column 3
(corrected amount) (Form 943, line 10) (difference)
-9,600.00 -6,900.00 -2,700.00

Report “-2,700.00” as your correction in column 4.

In this example, you’re claiming a credit for $2,700 in overreported tax for your 2023 Form 943. Always enter the same amount in column 4 (including any minus sign) that you enter in column 3.

Be sure to explain the reasons for this correction on line 41.

This is an Image: caution.gifOnly use line 12 to correct adjustments for fractions of cents, third-party sick pay, or group-term life insurance previously reported. File a separate Form 943-X for each year being corrected.

13. Qualified Small Business Payroll Tax Credit for Increasing Research Activities

This is an Image: caution.gifThe payroll tax credit election must be made on or before the due date of the originally filed income tax return (including extensions). Any election to take the payroll tax credit may be revoked only with the consent of the IRS.

If you're correcting the qualified small business payroll tax credit for increasing research activities that you reported on Form 943, line 12a (line 12 for years prior to 2020), enter the total corrected amount in column 1. In column 2, enter the amount you originally reported or as previously corrected. In column 3, enter the difference between columns 1 and 2.

Copy the amount in column 3 to column 4. However, to properly show the amount as a credit or balance due item, enter a positive number in column 3 as a negative number in column 4 or a negative number in column 3 as a positive number in column 4.

You must attach a corrected Form 8974 and explain the reasons for this correction on line 41.

14. Nonrefundable Portion of Credit for Qualified Sick and Family Leave Wages for Leave Taken After March 31, 2020, and Before April 1, 2021

This is an Image: taxtip.gifForm 943-X and these instructions use the terms “nonrefundable” and “refundable” when discussing credits. The term “nonrefundable” means the portion of the credit which is limited by law to certain taxes. The term “refundable” means the portion of the credit which is in excess of those taxes.

If you’re correcting the nonrefundable portion of the credit for qualified sick and family leave wages for leave taken after March 31, 2020, and before April 1, 2021, that you reported on Form 943, line 12b, enter the total corrected amount from Worksheet 1, Step 2, line 2j, in column 1. In column 2, enter the amount you originally reported or as previously corrected. In column 3, enter the difference between columns 1 and 2. For more information about the credit for qualified sick and family leave wages, go to IRS.gov/PLC.

Copy the amount in column 3 to column 4. However, to properly show the amount as a credit or balance due item, enter a positive number in column 3 as a negative number in column 4 or a negative number in column 3 as a positive number in column 4.

For corrections to 2020 Form 943, line 12b, the credit for qualified sick and family leave wages is only available for wages paid with respect to leave taken after March 31, 2020, and before January 1, 2021. For corrections to 2021, 2022, or 2023 Form 943, line 12b, the credit for qualified sick and family leave wages is only available for wages paid in 2021, 2022, or 2023 with respect to any leave taken after March 31, 2020, and before April 1, 2021. If you're correcting a year before 2020, don't enter any amount on line 14.

Definition of qualified sick and family leave wages for leave taken after March 31, 2020, and before April 1, 2021.

For purposes of the credit for qualified sick and family leave wages, qualified sick and family leave wages are wages for social security and Medicare tax purposes, determined without regard to the exclusions from the definition of employment under sections 3121(b)(1)–(22), that an employer pays that otherwise meet the requirements of the Emergency Paid Sick Leave Act (EPSLA) or the Emergency Family and Medical Leave Expansion Act (Expanded FMLA), as enacted under the FFCRA and amended by the COVID-related Tax Relief Act of 2020. However, don't include any wages otherwise excluded under sections 3121(b)(1)–(22) when reporting qualified sick and family leave wages on your employment tax return and when figuring the credit on Worksheet 1, Step 2, lines 2a and 2a(i), and on Step 2, lines 2e and 2e(i). Instead, include qualified sick leave wages and qualified family leave wages excluded from the definition of employment under sections 3121(b)(1)–(22) separately in Step 2, line 2a(iii) and/or line 2e(iii), respectively, before you figure your total credit in Step 2, line 2d (credit for qualified sick leave wages), or Step 2, line 2h (credit for qualified family leave wages).

The 2020 Instructions for Form 943 were released before the COVID-related Tax Relief Act of 2020 was enacted on December 27, 2020; therefore, Worksheet 1 in the 2020 Instructions for Form 943 didn't include lines to add the wages that meet an exclusion under sections 3121(b)(1)–(22) when figuring the credit for qualified sick and family leave wages. If your Form 943 for 2020 didn't claim the correct amount of the credit for qualified sick and family leave wages because you paid qualified sick leave wages and/or qualified family leave wages that meet an exclusion under sections 3121(b)(1)–(22), you may file Form 943-X and complete Worksheet 1 to claim the correct amount of the credit. You’ll also include on Form 943-X, lines 26 and 27, and on Worksheet 1 any qualified health plan expenses allocable to those wages. The appropriate lines related to the exclusions under sections 3121(b)(1)–(22) were added to Worksheet 1 in the 2021 Instructions for Form 943.

Example—Nonrefundable portion of credit for qualified sick and family leave wages increased.

You originally reported a $1,000 nonrefundable portion of the credit for qualified sick and family leave wages on Form 943, line 12b, for 2021. In March 2024, you discover that you made an error when figuring the credit. You use Worksheet 1 to refigure the nonrefundable portion of the credit for qualified sick and family leave wages and you determine that the credit is $2,000. To correct the error, figure the difference on Form 943‐X as shown next.

Column 1 (corrected amount) 2,000.00  
Column 2 (Form 943, line 12b) - 1,000.00  
Column 3 (difference) 1,000.00  

To properly show the credit increase as a reduction to your tax balance, enter the positive number in column 3 as a negative number in column 4. Here is how you would enter the numbers on Form 943‐X, line 14.

Column 1 Column 2 Column 3 Column 4
(corrected amount) (Form 943, line 12b) (difference) (tax correction)
2,000.00 1,000.00 1,000.00 -1,000.00

Be sure to explain the reasons for this correction on line 41.

15a. Nonrefundable Portion of Employee Retention Credit

Use line 15a only for corrections to a 2020 or 2021 Form 943.

This is an Image: taxtip.gifSection 206(c) of the Taxpayer Certainty and Disaster Tax Relief Act of 2020 removed the restriction on an employer who has received a Small Business Interruption Loan under the Paycheck Protection Program (PPP) from claiming the employee retention credit. The eligible employer can claim the employee retention credit on any qualified wages that aren't counted as payroll costs in obtaining PPP loan forgiveness. Any wages that could count toward eligibility for the employee retention credit or PPP loan forgiveness can be applied to either of these two programs but not both. If your Form 943 for 2020 didn't claim the correct amount for the employee retention credit because you received a Small Business Interruption Loan under the PPP, you may file Form 943-X and complete Worksheet 2 to claim the correct amount of the credit. For more information, see Notice 2021-20, 2021-11 I.R.B. 922, available at IRS.gov/irb/2021-11_IRB#NOT-2021-20; and Rev.

This is an Image: taxtip.gifFor corrections to a 2020 Form 943, the employee retention credit is only available for qualified wages paid after March 12, 2020, and before January 1, 2021. For corrections to a 2021 Form 943, the employee retention credit is only available for qualified wages paid after December 31, 2020, and before October 1, 2021, unless the employer was a recovery startup business. An employer that was a recovery startup business could also claim the employee retention credit for wages paid after September 30, 2021, and before January 1, 2022. Adjustments to the nonrefundable portion of the employee retention credit for qualified wages paid after March 12, 2020, and before July 1, 2021, are reported on Form 943-X, line 15a, and adjustments to the refundable portion of the credit are reported on Form 943-X, line 24a. Adjustments to qualified wages for the employee retention credit are reported on Form 943-X, line 28. Adjustments to qualified health plan expenses allocable to the employee retention credit are reported on Form 943-X, line 29. If you claimed the employee retention credit on your original 2020 Form 943 or your original 2021 Form 943 for qualified wages paid before July 1, 2021, and you make any corrections on Form 943-X for the year to amounts used to figure this credit, you’ll need to refigure the amount of the credit using Worksheet 2. You’ll also use this worksheet to figure the credit for qualified wages paid after March 12, 2020, and before July 1, 2021, if you're claiming the credit for the first time on Form 943-X.

Instructions for Qualified Wages Paid After June 30, 2021, and Before January 1, 2022

This is an Image: caution.gifThe Infrastructure Investment and Jobs Act amends section 3134 of the Internal Revenue Code, as enacted under the ARP, to limit the availability of the employee retention credit in the fourth quarter of 2021 to employers that are recovery startup businesses, as defined in section 3134(c)(5). Thus, for wages paid after September 30, 2021, and before January 1, 2022, only the wages paid by recovery startup businesses can be qualified wages. See the 2021 revision of the Instructions for Form 943 for more information about a recovery startup business.

If you're correcting the nonrefundable portion of the employee retention credit for qualified wages paid after June 30, 2021, and before January 1, 2022, that you reported on Form 943, line 12c, enter the total corrected amount from Worksheet 4, Step 2, line 2h, in column 1. In column 2, enter the amount you originally reported or as previously corrected. In column 3, enter the difference between columns 1 and 2.

Copy the amount in column 3 to column 4. However, to properly show the amount as a credit or balance due item, enter a positive number in column 3 as a negative number in column 4 or a negative number in column 3 as a positive number in column 4. For an example of how to report amounts in columns 1–4 for an employment tax credit, see the instructions for line 14, earlier.

For more information about the employee retention credit for qualified wages paid after June 30, 2021, and before January 1, 2022, see Notice 2021-49 and Rev. Proc. 2021-33. See Notice 2021-65, 2021-51 I.R.B. 880, available at IRS.gov/irb/2021-51_IRB#NOT-2021-65, for modifications to Notice 2021-49.

Be sure to explain the reasons for this correction on line 41.

This is an Image: taxtip.gifFor corrections to a 2021 Form 943, the employee retention credit is only available for qualified wages paid after December 31, 2020, and before October 1, 2021, unless the employer was a recovery startup business. An employer that was a recovery startup business could also claim the employee retention credit for wages paid after September 30, 2021, and before January 1, 2022. Adjustments to the nonrefundable portion of the employee retention credit for qualified wages paid after June 30, 2021, and before January 1, 2022, are reported on Form 943-X, line 15a, and adjustments to the refundable portion of the credit are reported on Form 943-X, line 24a. Adjustments to qualified wages for the employee retention credit are reported on Form 943-X, line 28. Adjustments to qualified health plan expenses allocable to the employee retention credit are reported on Form 943-X, line 29. If you claimed the employee retention credit on your original 2021 Form 943 and you make any corrections on Form 943-X to amounts used to figure the credit for qualified wages paid after June 30, 2021, and before January 1, 2022, you'll need to refigure the amount of the credit using Worksheet 4. You'll also use this worksheet to figure this credit if you’re claiming the credit for the first time on Form 943-X.

For corrections to 2021, 2022, or 2023 Form 943, line 12d, the credit for qualified sick and family leave wages is only available for wages paid in 2021, 2022, or 2023 with respect to any leave taken after March 31, 2021, and before October 1, 2021. If you're correcting a year before 2021, don't enter any amount on line 15b.

Definition of qualified sick and family leave wages for leave taken after March 31, 2021, and before October 1, 2021.

For purposes of this credit, qualified sick leave wages and qualified family leave wages are wages for social security and Medicare tax purposes, determined without regard to the exclusions from the definition of employment under sections 3121(b)(1)–(22), that an employer pays that otherwise meet the requirements of the EPSLA or Expanded FMLA, as enacted under the FFCRA and amended for purposes of the ARP. Taxable qualified sick leave wages and qualified family leave wages for leave taken after March 31, 2021, and before October 1, 2021, were included on Form 943, line 2, and can be adjusted only on Form 943-X, line 6. Total qualified sick and family leave wages for leave taken after March 31, 2021, and before October 1, 2021, including any qualified leave wages that were above the social security wage base and any qualified leave wages excluded from the definition of employment under sections 3121(b)(1)–(22), were included on Form 943, lines 22 and 25, respectively, and can be adjusted only on Form 943-X, lines 31 and 34, respectively. Use Worksheet 3 to figure your credit.

Be sure to explain the reasons for this correction on line 41.

16–19. Special Additions to Wages for Federal Income Tax, Social Security Taxes, Medicare Taxes, and Additional Medicare Tax

Section 3509 provides special rates for the employee share of social security tax, Medicare tax, Additional Medicare Tax, and federal income tax withholding when workers are reclassified as employees in certain circumstances. The applicable rate depends on whether you filed required information returns. An employer can’t recover any tax paid under this provision from the employees. The full employer share of social security and Medicare taxes is due for all reclassifications.

Note.

Section 3509 rates aren’t available if you intentionally disregarded the requirements to withhold taxes from the employee, or if you withheld federal income tax but didn’t withhold social security and Medicare taxes. Section 3509 rates are also not available for certain statutory employees.

On lines 16–19, enter only corrections to wages resulting from reclassifying certain workers as employees when section 3509 rates are used to calculate the taxes.

If the employer issued the required information returns, use the section 3509 rates as follows.

  • For social security tax, use the employer rate of 6.2% plus 20% of the employee rate of 6.2%, for a total rate of 7.44% of wages.

  • For Medicare tax, use the employer rate of 1.45% plus 20% of the employee rate of 1.45%, for a total rate of 1.74% of wages.

  • For Additional Medicare Tax, 0.18% (20% of the employee rate of 0.9%) of wages subject to Additional Medicare Tax.

  • For federal income tax withholding, the rate is 1.5% of wages.

If the employer didn’t issue the required information returns, use the section 3509 rates as follows.

  • For social security tax, use the employer rate of 6.2% plus 40% of the employee rate of 6.2%, for a total rate of 8.68% of wages.

  • For Medicare tax, use the employer rate of 1.45% plus 40% of the employee rate of 1.45%, for a total rate of 2.03% of wages.

  • For Additional Medicare Tax, 0.36% (40% of the employee rate of 0.9%) of wages subject to Additional Medicare Tax.

  • For federal income tax withholding, the rate is 3.0% of wages.

Unlike some other lines on Form 943-X, enter in column 1 only the corrected wages for workers being reclassified, not the amount paid to all employees. Enter in column 2 previously reported wages (if any) to reclassified employees. To get the amount for column 4, use the applicable section 3509 rates. If you filed the required information returns for some employees but didn’t file them for other employees, be sure to use the applicable rates for each employee when calculating the amounts in column 4 and show your calculations on line 41. The tax correction in column 4 will be a positive number if you increased the amount of wages you previously reported. See the instructions for line 40, later, for more information.

20. Subtotal

Combine the amounts on lines 6–19 of column 4 and enter the total on line 20.

Example.

You entered “-500.00” in column 4 of line 6, “-100.00” in column 4 of line 9, and “1,400.00” in column 4 of line 11. Combine these amounts and enter “800.00” in column 4 of line 20.

Line 6 (column 4) -500.00  
Line 9 (column 4) -100.00  
Line 11 (column 4) + 1,400.00  
Line 20 (column 4) 800.00  

21. Deferred Amount of the Employer Share of Social Security Tax

Use Form 943-X, line 21, if you need to correct the deferred amount of the employer share of social security tax that you reported on your 2020 Form 943, line 14b. Enter the total corrected amount in column 1. In column 2, enter the amount you originally reported or as previously corrected by you or the IRS. In column 3, enter the difference between columns 1 and 2.

Copy the amount in column 3 to column 4. However, because an increase to the deferred amount of the employer share of social security tax defers the payment due, to properly show the amount as a deferral of payment, enter a positive number in column 3 as a negative number in column 4. A decrease to the deferred amount of the employer share of social security tax decreases the payment you can defer and must be shown as a balance due item; therefore, to properly show the amount as a balance due item, enter a negative number in column 3 as a positive number in column 4.

If you're filing Form 943-X to increase the amount of social security wages paid on or after March 27, 2020, and before January 1, 2021, so that there is an additional amount of social security tax that hasn't yet been paid, and hasn't yet been deferred, then you may use Form 943-X to increase the amount of the deferred employer share of social security tax originally reported on Form 943, line 14b. If you're filing Form 943-X to decrease the amount of social security wages paid on or after March 27, 2020, and before January 1, 2021, so that there is a decrease in the amount of social security tax that is eligible for deferral, then you must use Form 943-X to decrease the amount of the deferred employer share of social security tax originally reported on Form 943, line 14b, if the decrease in wages causes the amount you originally deferred to exceed the amount that is now eligible for deferral. Otherwise, you may only correct the amount of the deferred employer share of social security tax if the amount originally reported on Form 943, line 14b, isn't the amount you actually deferred (for example, you incorrectly reported the amount that you actually deferred). If you already paid the correct amount of the employer share of social security tax during the payroll tax deferral period, you may not subsequently defer the payment by filing Form 943-X. See IRS.gov/ETD for more information about the interaction of credits and the deferral of employment tax deposits and payments.

The deferred amount of the employer share of social security tax was only available for deposits and payments due on or after March 27, 2020, and before January 1, 2021, as well as deposits and payments due after January 1, 2021, that were required for wages paid during the applicable period. One-half of the deferred amount of the employer share of social security tax was due by December 31, 2021, and the remainder was due by December 31, 2022. Because both December 31, 2021, and December 31, 2022, were nonbusiness days, payments made on the next business day were considered timely. Any payments or deposits you made before December 31, 2021, were first applied against your payment due on December 31, 2021, and then applied against your payment due on December 31, 2022. For more information about the deferral of employment tax deposits, go to IRS.gov/ETD and see the Instructions for Form 943, available at IRS.gov/Form943.

Be sure to explain the reasons for any correction on line 41.

22. Deferred Amount of the Employee Share of Social Security Tax

Use Form 943-X, line 22, if you need to correct the deferred amount of the employee share of social security tax that you reported on your 2020 Form 943, line 14c. Enter the total corrected amount in column 1. In column 2, enter the amount you originally reported or as previously corrected by you or the IRS. In column 3, enter the difference between columns 1 and 2.

Copy the amount in column 3 to column 4. However, because an increase to the deferred amount of the employee share of social security tax defers the payment due, to properly show the amount as a deferral of payment, enter a positive number in column 3 as a negative number in column 4. A decrease to the deferred amount of the employee share of social security tax decreases the payment you can defer and must be shown as a balance due item; therefore, to properly show the amount as a balance due item, enter a negative number in column 3 as a positive number in column 4.

You may only correct the amount of the deferred employee share of social security tax if the amount originally reported on Form 943, line 14c, isn't the amount you actually deferred (for example, you incorrectly reported the amount that you actually deferred). If you already paid the correct amount of the employee's share of social security tax, you may not subsequently defer the payment by filing Form 943-X.

The deferred amount of the employee share of social security tax was only available for social security wages of less than $4,000 paid to an employee in any biweekly pay period (or the equivalent threshold amount for other pay periods) paid on a pay date during the period beginning on September 1, 2020, and ending on December 31, 2020. The due date for withholding and payment of the deferred employee share of social security tax was postponed until the period beginning on January 1, 2021, and ending on December 31, 2021. The employer was liable to pay the deferred employee share of social security tax to the IRS and was required to do so before January 1, 2022, to avoid interest, penalties, and additions to tax on those amounts. Because January 1, 2022, was a nonbusiness day, payments made on January 3, 2022, were considered timely. For more information about the deferral of the employee share of social security tax, see Notice 2020‐65, 2020‐38 I.R.B. 567, available at IRS.gov/irb/2020-38_IRB#NOT-2020-65; and Notice 2021-11, 2021-06 I.R.B. 827, available at IRS.gov/irb/2021-06_IRB#NOT-2021-11.

Be sure to explain the reasons for any correction on line 41.

Corrections to Form 943, Line 14g (For 2020) or Line 14i (For 2021)

Form 943-X doesn't include a line to correct amounts reported on Form 943, line 14g (14i), for the total advances received from filing Form(s) 7200 for the year. If a discrepancy exists between the amount reported on Form 943 and the amount of advance payments issued, the IRS will generally correct the amount reported on Form 943, line 14g (14i), to match the amount of advance payments issued. However, aggregate filers may need to correct the amount reported on Form 943, line 14g (14i), to reflect the correct advance payments received by their clients or customers. If you're an aggregate filer that needs to correct the amount reported on Form 943, line 14g (14i), include any increase or decrease to the amount in the "Total" reported on Form 943-X, line 25; write "Correction to line 14g (14i)" on the dotted line to the left of the entry box on line 25; explain your correction on line 41; and attach Schedule R (Form 943) to Form 943-X to show corrections for your clients or customers.

25. Total

Combine the amounts from column 4 on lines 20–24c and enter the result on line 25.

Your credit.

If the amount entered on line 25 is less than zero, for example, “-115.00,” you have a credit because you overreported your federal employment taxes.

  • If you checked the box on line 1, include this amount on the "Total deposits" line of Form 943 for the year during which you filed Form 943-X. Don’t make any changes to your record of federal tax liability reported on Form 943, line 17, or Form 943-A, unless you were assessed an FTD penalty. For more information, see the Form 943-A instructions.

  • If you checked the box on line 2, you’re filing a claim for refund or abatement of the amount shown.

If your credit is less than $1, we will send a refund or apply it to your next return only if you ask us in writing to do so.

Amount you owe.

If the amount on line 25 is a positive number, you must pay the amount you owe by the time you file Form 943-X. You may not use any credit that you show on another Form 943-X to pay the amount you owe, even if you filed for the amount you owe and the credit at the same time.

If you owe tax and are filing a timely Form 943-X, don’t file an amended Form 943-A unless you were assessed an FTD penalty caused by an incorrect, incomplete, or missing Form 943-A. Don’t include the tax increase reported on Form 943-X on any amended Form 943-A you file.

If you owe tax and are filing a late Form 943-X, that is, after the due date of Form 943 for the year in which you discovered the error, you must file an amended Form 943-A with the Form 943-X. Otherwise, the IRS may assess an “averaged” FTD penalty. The total tax reported on Form 943-A, line M, must match the corrected tax (Form 943, line 13, combined with any correction reported on Form 943-X, line 20) for the year, less any previous abatements and interest-free tax assessments.

Payment methods.

You may pay the amount you owe on line 25 electronically using the Electronic Federal Tax Payment System (EFTPS), by credit card or debit card, or by a check or money order.

  • The preferred method of payment is EFTPS. For more information, go to EFTPS.gov, or call 800-555-4477 (800-244-4829 (Spanish) or 303-967-5916 if you're outside the United States (toll call)). To contact EFTPS using Telecommunications Relay Services (TRS) for people who are deaf, hard of hearing, or have a speech disability, dial 711 and then provide the TRS assistant the 800-555-4477 number above or 800-733-4829. Additional information about EFTPS is also available in Pub. 966.

  • To pay by credit or debit card, go to IRS.gov/PayByCard. Your payment will be processed by a payment processor who will charge a processing fee.

  • If you pay by check or money order, make it payable to “United States Treasury.” On your check or money order, be sure to write your EIN, “Form 943-X,” and the year corrected. You don’t have to pay if the amount you owe is less than $1.

For lines 26–38, you’ll only enter amounts in columns 1, 2, and 3. These lines don't have an entry space for column 4 because these adjustments don't directly result in an increase or decrease to your tax. The amounts entered on lines 26–36 are amounts that you use on Worksheets 1–5, as applicable, to figure your credits. If you reported an incorrect amount on lines 18–29 on your original Form 943, then you’ll use lines 26–38 of Form 943‐X to report the correction. Use Worksheets 1–5, as applicable, to refigure your credits based on the corrected amounts reported in column 1. Be sure to explain the reasons for your corrections to lines 26–38 on line 41.

37. If You’re Eligible for the Employee Retention Credit in the Third Quarter of 2021 Solely Because Your Business Is a Recovery Startup Business . . .

Whether you complete line 37 to tell us if you're eligible for the employee retention credit in the third quarter of 2021 solely because your business is a recovery startup business depends on its applicability and whether you originally reported an amount on your 2021 Form 943, line 28.

  • If you reported the total of any amounts included on lines 12c and 14e on line 28 for the third quarter on your originally filed 2021 Form 943 but that is no longer accurate, explain in detail on line 41 why you no longer think that you’re a recovery startup business and the reasons that you still qualify for the employee retention credit.

  • If you didn’t report the total of any amounts included on lines 12c and 14e on line 28 for the third quarter on your originally filed 2021 Form 943 and this still doesn’t apply, don’t complete line 37.

  • If you didn’t report the total of any amounts included on lines 12c and 14e for the third quarter on your originally filed 2021 Form 943 but you’re now claiming the employee retention credit as a recovery startup business, complete line 37 with the total of the corrected amounts included on Form 943-X, lines 15a and 24a.

Recovery startup business.

For the third quarter of 2021, a recovery startup business is an employer that:

  • Began carrying on a trade or business after February 15, 2020;

  • Had average annual gross receipts of $1 million or less for the 3 tax years ending with the tax year before the calendar quarter in which the employee retention credit is claimed; and

  • Isn't otherwise eligible for the employee retention credit because business operations aren't fully or partially suspended due to a governmental order or because gross receipts (within the meaning of section 448(c) or, if you're a tax-exempt organization, section 6033) aren't less than 80% of the gross receipts for the same calendar quarter in calendar year 2019.

38. If You’re Eligible for the Employee Retention Credit in the Fourth Quarter of 2021 Solely Because Your Business Is a Recovery Startup Business . . .

For the fourth quarter of 2021, only a recovery startup business may claim the employee retention credit. Whether you complete line 38 to tell us if you're eligible for the employee retention credit in the fourth quarter of 2021 solely because your business is a recovery startup business depends on its applicability and whether you originally reported an amount on your 2021 Form 943, line 29.

  • If you reported the total of any amounts included on lines 12c and 14e on line 29 for the fourth quarter on your originally filed 2021 Form 943 but that is no longer accurate, explain in detail on line 41 why you no longer think that you're a recovery startup business and the reasons that you still qualify for the employee retention credit.

  • If you didn’t report the total of any amounts included on lines 12c and 14e on line 29 for the fourth quarter on your originally filed 2021 Form 943 and this still doesn’t apply, don’t complete line 38.

  • If you didn’t report the total of any amounts included on lines 12c and 14e for the fourth quarter on your originally filed 2021 Form 943 but you’re now claiming the employee retention credit as a recovery startup business, complete line 38 with the total of the corrected amounts included on Form 943-X, lines 15a and 24a.

For the fourth quarter of 2021, a recovery startup business is an employer that began carrying on a trade or business after February 15, 2020, and had average annual gross receipts of $1 million or less for the 3 tax years ending with the tax year before the calendar quarter in which the employee retention credit is claimed.

Part 4: Explain Your Corrections for the Calendar Year You’re Correcting

39. Corrections of Both Underreported and Overreported Amounts

Check the box on line 39 if any corrections you entered on lines 6–19, lines 21–24c, or lines 26–38, column 3, reflect both underreported and overreported amounts.

Example.

If you had an increase to social security wages of $15,000 for Nathan Black and a decrease to social security wages of $5,000 for Leah Green, you would enter $10,000 on line 6, column 3. That $10,000 represents the net change from offsetting corrections.

On line 41, you must explain the reasons for both the $15,000 increase and the $5,000 decrease.

40. Did You Reclassify Any Workers?

Check the box on line 40 if you reclassified any workers to be independent contractors or nonemployees. Also check this box if the IRS or you determined that workers you treated as independent contractors or nonemployees should be classified as employees. On line 41, give us a detailed reason why any worker was reclassified and, if you used section 3509 rates on lines 16–19 for any worker reclassified as an employee, explain why section 3509 rates apply and what rates you used.

Return not filed because you didn’t treat any workers as employees.

If you didn’t previously file Form 943 because you mistakenly treated workers as independent contractors or as nonemployees, file a Form 943 for each delinquent year.

On each Form 943 for which you’re entitled to use section 3509 rates, complete the following steps.

  • Write “Misclassified Employees” in bold letters across the top margin of page 1.

  • Enter a zero on line 13.

  • Complete the signature area.

  • Attach a completed Form 943-X (see instructions next).

On each attached Form 943-X, complete the following steps.

  • Complete the top of Form 943-X, including the date you discovered the error.

  • Enter the wage amounts on lines 16–19, column 1.

  • Enter zeros on lines 16–19, column 2.

  • Complete columns 3 and 4 as instructed in Part 3.

  • Provide a detailed statement on line 41.

  • Complete the signature area.

This is an Image: caution.gifIf you can’t use section 3509 rates (for example, because the workers you treated as nonemployees were certain statutory employees), file a Form 943 for each delinquent year. Write “Misclassified Employees” in bold letters across the top margin of page 1 of each Form 943. Complete Form 943 using the Instructions for Form 943. Attach a Form 943-X to each Form 943. Complete the top of Form 943-X, including the date you discovered the error, and provide a detailed explanation on line 41.

41. Explain Your Corrections

Treasury regulations require you to explain in detail the grounds and facts relied upon to support each correction. On line 41, describe in detail each correction you entered in column 4 on lines 6–19 and lines 21–24c. Also use line 41 to describe in detail corrections made on lines 26–38. If you need more space, attach additional sheets, but be sure to write your name, EIN, “Form 943-X,” and the calendar year you’re correcting on the top of each sheet.

You must describe the events that caused the underreported or overreported amounts. Explanations such as “social security and Medicare wages were overstated,” “administrative/payroll errors were discovered,” or “taxes were not withheld” are insufficient and may delay processing your Form 943-X because the IRS may need to ask for a more complete explanation.

Provide the following information in your explanation for each correction.

  • Form 943-X line number(s) affected.

  • Date you discovered the error.

  • Amount of the error.

  • Cause of the error.

You may report the information in paragraph form. The following paragraph is an example.

“The $1,000 difference shown in column 3 of lines 6 and 9 was discovered on May 15, 2024, during an internal payroll audit. We discovered that we included $1,000 of wages for one of the employees twice. This correction removes the reported wages that were never paid.”

For corrections shown on lines 16–19, explain why the correction was necessary and attach any notice you received from the IRS.

Part 5: Sign Here

You must complete all five pages of Form 943-X and sign it on page 5. If you don’t sign, processing of Form 943-X will be delayed.

  • Single-member LLC treated as a disregarded entity for federal income tax purposes—The owner of the LLC or a principal officer duly authorized to sign.

Paid Preparer Use Only

A paid preparer must sign Form 943-X and provide the information in the Paid Preparer Use Only section of Part 5 if the preparer was paid to prepare Form 943-X and isn’t an employee of the filing entity. Paid preparers must sign paper returns with a manual signature. The preparer must give you a copy of the return in addition to the copy to be filed with the IRS.

If you’re a paid preparer, enter your Preparer Tax Identification Number (PTIN) in the space provided. Include your complete address. If you work for a firm, enter the firm's name and the EIN of the firm. You can apply for a PTIN online or by filing Form W-12. For more information about applying for a PTIN online, go to IRS.gov/PTIN. You can’t use your PTIN in place of the EIN of the tax preparation firm.

Generally, you’re not required to complete this section if you’re filing the return as a reporting agent and have a valid Form 8655 on file with the IRS. However, a reporting agent must complete this section if the reporting agent offered legal advice, for example, advising the client on determining whether its workers are employees or independent contractors for federal tax purposes.
