1. Taxpayer Identification Numbers

If you are required to withhold any federal income, social security, or Medicare taxes, you will need an employer identification number (EIN) for yourself and you will need the social security number (SSN) of each employee and the name of each employee as shown on the employee's social security card.

Employer identification number (EIN).   An employer identification number (EIN) is a nine-digit number that the IRS issues. The digits are arranged as follows: 00-0000000. It is used to identify the tax accounts of employers and certain others who have no employees. Use your EIN on all of the items that you send to the IRS and SSA.

  If you do not have an EIN, you may apply for one online. Go to the IRS website at www.irs.gov and click on the Online EIN Application link. You may also apply for an EIN by calling 1-800-829-4933, or you can fax or mail Form SS-4 to the IRS. Do not use a social security number (SSN) in place of an EIN.

  If you do not have an EIN by the time a return is due, write “Applied For” and the date you applied for it in the space shown for the number. If you took over another employer's business, do not use that employer's EIN.

  See Depositing without an EIN in section 7 if you must make a tax deposit and you do not have an EIN.

  You should have only one EIN. If you have more than one, and are not sure which one to use, call the toll-free Business and Specialty Tax Line at 1-800-829-4933 (TTY/TDD users can call 1-800-829-4059). Provide the EINs that you have, the name and address to which each number was assigned, and the address of your principal place of business. The IRS will tell you which EIN to use.

  For more information, see Publication 1635, Understanding Your EIN, or Publication 583, Starting a Business and Keeping Records.

When you receive your EIN.   If you are a new employer that indicated a federal tax obligation when requesting an EIN, you will be pre-enrolled in the Electronic Federal Tax Payment System (EFTPS). You will receive information in your Employer Identification Number (EIN) Package about Express Enrollment and an additional mailing containing your EFTPS personal identification number (PIN) and instructions for activating your PIN. Call the toll-free number located in your “How to Activate Your Enrollment” brochure to activate your enrollment and begin making your payroll tax deposits. Be sure to tell your payroll provider about your EFTPS enrollment. Consider using EFTPS to make your other federal tax payments electronically as well. You should activate your EFTPS enrollment now even if you plan to deposit using FTD coupons (Form 8109) because it may take 5 to 6 weeks to receive the coupons and you may be required to make a deposit while waiting for them.

Social security number (SSN).   An employee's social security number (SSN) consists of nine digits arranged as follows: 000-00-0000. You must obtain each employee's name and SSN as shown on the employee's social security card because you must enter them on Form W-2. You may, but are not required to, photocopy the social security card if the employee provides it. If you do not show the employee's correct name and SSN on Form W-2, you may owe a penalty unless you have reasonable cause. See Publication 1586, Reasonable Cause Regulations and Requirements for Missing and Incorrect Name/TINs.

Applying for a social security card.   Any employee without a social security card can get one by completing Form SS-5, Application for a Social Security Card, and submitting the necessary documentation to SSA. You can get Form SS-5 at SSA offices, by calling 1-800-772-1213, or from the SSA website at
www.socialsecurity.gov/online/ss-5.html. The employee must complete and sign Form SS-5; it cannot be filed by the employer. You may be asked to supply a letter to accompany Form SS-5 if the employee has exceeded his or her yearly or lifetime limit for the number of replacement cards allowed.

Applying for a social security number.   If you file Form W-2 on paper and your employee has applied for an SSN but does not have one when you must file Form W-2, enter “Applied For” on the form. If you are filing electronically, enter all zeros (000-00-0000) in the social security number field. When the employee receives the SSN, file Copy A of Form W-2c, Corrected Wage and Tax Statement, with the SSA to show the employee's SSN. Furnish Copies B, C, and 2 of Form W-2c to the employee. Up to five forms W-2c per Form W-3c (up to 50 W-3c reports) may be created and submitted to the SSA over the Internet. For more information, visit Social Security's Employer Reporting Instructions and Information webpage at
www.socialsecurity.gov/employer. Advise your employee to correct the SSN on his or her original Form W-2.

Correctly record the employee's name.   Record the name and number of each employee as they are shown on the employee's social security card. If the employee's name is not correct as shown on the card (for example, because of marriage or divorce), the employee should request a corrected card from the SSA. Continue to report the employee's wages under the old name until he or she shows you an updated social security card with the new name.

  If SSA issues the employee a replacement card after a name change, or a new card with a different social security number after a change in alien work status, file a Form W-2c to correct the name/SSN reported on the most recently filed Form W-2. It is not necessary to correct other years if the previous name and SSN was used for years before the most recent Form W-2.

IRS individual taxpayer identification numbers (ITINs) for aliens.   Do not accept an individual taxpayer identification number (ITIN) in place of an SSN for either employee identification or for work. An ITIN is issued for use by resident and nonresident aliens who need identification for tax purposes, but who are not eligible for U.S. employment. The ITIN is a nine-digit number formatted like an SSN (for example, NNN-NN-NNNN). However, it begins with the number “9” and has either a “7” or “8” as the fourth digit (for example, 9NN-7N-NNNN or 9NN-8N-NNNN).

  
Caution
An individual with an ITIN who later becomes eligible to work in the United States must obtain an SSN. If the individual is currently eligible to work in the United States, instruct the individual to apply for an SSN and follow the instructions under Applying for a social security number on page 6. Do not use an ITIN in place of an SSN on Form W-2.

Verification of social security numbers.   The SSA offers employers and authorized reporting agents three methods for verifying employee SSNs.
  • Internet. Verify up to 10 names and numbers (per screen) online and receive immediate results, or upload batch files of up to 250,000 names and numbers and usually receive results the next government business day. Visit www.socialsecurity.gov/employer and click on the Verify Social Security Numbers Online link.

  • Telephone. Verify up to five names and numbers by calling 1-800-772-6270 or 1-800-772-1213.

  • Paper. Verify up to 300 names and numbers by submitting a paper request. For information, see Appendix A in the Social Security Number Verification System (SSNVS) Handbook at www.socialsecurity.gov/employer/ssnvs_handbk.htm#appendix.

  Some verification methods require registration. For more information, call 1-800-772-6270.

2. Who Are Employees?

Generally, employees are defined either under common law or under statutes for certain situations.

Employee status under common law.   Generally, a worker who performs services for you is your employee if you have the right to control what will be done and how it will be done. This is so even when you give the employee freedom of action. What matters is that you have the right to control the details of how the services are performed. Get Publication 15-A, Employer's Supplemental Tax Guide, for more information on how to determine whether an individual providing services is an independent contractor or an employee.

You are responsible for withholding and paying employment taxes for your employees. You are also required to file employment tax returns. These requirements do not apply to amounts that you pay to independent contractors. The rules discussed in this publication apply only to workers who are your employees.

In general, you are an employer of farmworkers if your employees:

  • Raise or harvest agricultural or horticultural products on your farm (including the raising and feeding of livestock);

  • Work in connection with the operation, management, conservation, improvement, or maintenance of your farm and its tools and equipment;

  • Provide services relating to salvaging timber, or clearing land of brush and other debris, left by a hurricane (also known as hurricane labor);

  • Handle, process, or package any agricultural or horticultural commodity if you produced over half of the commodity (for a group of up to 20 unincorporated operators, all of the commodity); or

  • Do work for you related to cotton ginning, turpentine, gum resin products, or the operation and maintenance of irrigation facilities.

For this purpose, the term “farm” includes stock, dairy, poultry, fruit, fur-bearing animal, and truck farms, as well as plantations, ranches, nurseries, ranges, greenhouses or other similar structures used primarily for the raising of agricultural or horticultural commodities, and orchards.

Farmwork does not include reselling activities that do not involve any substantial activity of raising agricultural or horticultural commodities, such as a retail store or a greenhouse used primarily for display or storage.

The table on page 24, How Do Employment Taxes Apply to Farmwork, distinguishes between farm and nonfarm activities, and also addresses rules that apply in special situations.

Crew Leaders

If you are a crew leader, you are an employer of farmworkers. A crew leader is a person who furnishes and pays (either on his or her own behalf or on behalf of the farm operator) workers to do farmwork for the farm operator. If there is no written agreement between you and the farm operator stating that you are his or her employee and if you pay the workers (either for yourself or for the farm operator), then you are a crew leader. For FUTA tax rules, see section 10.

Husband-Wife Business

If you and your spouse jointly own and operate a farm or nonfarm business and share in the profits and losses, you are partners in a partnership, whether or not you have a formal partnership agreement. See Publication 541, Partnerships, for more details. The partnership is considered the employer of any employees, and is liable for any employment taxes due on wages paid to its employees.

Exception—Qualified joint venture.   If you and your spouse materially participate (see Material participation on page F-2 of the Instructions for Schedule F) as the only members of a jointly owned and operated business, and you file a joint Form 1040, you can make a joint election to be taxed as a qualified joint venture instead of a partnership. Spouses electing qualified joint venture status are treated as sole proprietors for federal tax purposes. Either of the sole proprietor spouses may report and pay the employment taxes due on wages paid to the employees, using the EIN of that spouse's sole proprietorship.

Exception—Community income.   If you and your spouse wholly own an unincorporated business as community property under the community property laws of a state, foreign country, or U.S. possession, you can treat the business either as a sole proprietorship (of the spouse who carried on the business) or a partnership. You may still make an election to be taxed as a qualified joint venture instead of a partnership. See Exception—Qualified joint venture above.

3. Taxable Wages

Cash wages that you pay to employees for farmwork are subject to social security and Medicare taxes. If the wages are subject to social security and Medicare taxes, they are also subject to federal income tax withholding. You may also be liable for FUTA tax, which is not withheld by you or paid by the employee. FUTA tax is discussed in section 10. Cash wages include checks, money orders, etc. Do not count as cash wages the value of food, lodging, and other noncash items.

For more information on what payments are considered taxable wages, see Publication 15 (Circular E).

Commodity wages.   Commodity wages are not cash and are not subject to social security and Medicare taxes or federal income tax withholding. However, noncash payments, including commodity wages, are treated as cash wages (see above) if the substance of the transaction is a cash payment. These noncash payments are subject to social security and Medicare taxes and federal income tax withholding.

Family members.   Generally, the wages that you pay to family members who are your employees are subject to social security and Medicare taxes, federal income tax withholding, and FUTA tax. However, certain exemptions may apply for your child, spouse, or parent. See the table, How Do Employment Taxes Apply to Farmwork, on
page 24.

Household employees.   The wages of an employee who performs household services, such as a maid, babysitter, gardener, or cook, in your home are not subject to social security and Medicare taxes if you pay that employee cash wages of less than $1,600 in 2008.

  Social security and Medicare taxes do not apply to cash wages for housework in your private home if it was done by your spouse or your child under age 21. Nor do the taxes apply to housework done by your parent unless:
  • You have a child living in your home who is under age 18 or has a physical or mental condition that requires care by an adult for at least 4 continuous weeks in a calendar quarter, and

  • You are a widow or widower, or divorced and not remarried, or have a spouse in the home who, because of a physical or mental condition, cannot care for your child for at least 4 continuous weeks in the quarter.

  For more information, see Publication 926, Household Employer's Tax Guide.

  
Caution
Wages for household work may not be a deductible farm expense. See Publication 225, Farmer's Tax Guide.

Share farmers and alien workers.   You do not have to withhold or pay social security and Medicare taxes on amounts paid to share farmers under share-farming arrangements or on wages paid to alien workers admitted under section 101(a)(15)(H)(ii)(a) of the Immigration and Nationality Act on a temporary basis to perform agricultural labor (that is, “H-2(A)” visa workers).

4. Social Security and Medicare Taxes

Generally, you must withhold social security and Medicare taxes on all cash wage payments that you make to your employees.

The $150 Test or the $2,500 Test

All cash wages that you pay to an employee during the year for farmwork are subject to social security and Medicare taxes and federal income tax withholding if either of the two tests below is met.

  • You pay cash wages to an employee of $150 or more in a year for farmwork (count all cash wages paid on a time, piecework, or other basis). The $150 test applies separately to each farmworker that you employ. If you employ a family of workers, each member is treated separately. Do not count wages paid by other employers.

  • The total that you pay for farmwork (cash and noncash) to all your employees is $2,500 or more during the year.

Exceptions.   The $150 and $2,500 tests do not apply to wages that you pay to a farmworker who receives less than $150 in annual cash wages and the wages are not subject to social security and Medicare taxes, or federal income tax withholding, even if you pay $2,500 or more in that year to all of your farmworkers if the farmworker:
  • Is employed in agriculture as a hand-harvest laborer,

  • Is paid piece rates in an operation that is usually paid on a piece-rate basis in the region of employment,

  • Commutes daily from his or her permanent home to the farm, and

  • Had been employed in agriculture less than 13 weeks in the preceding calendar year.

  Amounts that you pay to these seasonal farmworkers, however, count toward the $2,500-or-more test to determine whether wages that you pay to other farmworkers are subject to social security and Medicare taxes.

Social Security and Medicare Tax Withholding

For wages paid in 2008 the social security tax rate is 6.2%, for both the employee and employer, on the first $102,000 paid to each employee. You must withhold at this rate from each employee and pay a matching amount.

The Medicare tax rate is 1.45% each for the employer and the employee on all wages. You must withhold at this rate from each employee and pay a matching amount.

Employee share paid by employer.   If you would rather pay a household or agricultural employee's share of the social security and Medicare taxes without withholding them from his or her wages, you may do so. If you do not withhold the taxes, however, you must still pay them. Any employee social security and Medicare taxes that you pay is additional income to the employee. Include it in the employee's Form W-2, box 1, but do not count it as social security and Medicare wages, boxes 3 and 5. Also, do not count the additional income as wages for FUTA tax purposes. Different rules apply to employer payments of social security and Medicare taxes for non-household and non-agricultural employees. See section 7 of
Publication 15-A.

  Social security and Medicare taxes apply to most payments of sick pay, including payments made by third parties such as insurance companies. For details, see
Publication 15-A.

Withholding social security and Medicare taxes on nonresident alien employees.   In general, if you pay wages to nonresident alien employees, you must withhold social security and Medicare taxes as you would for a U.S. citizen or resident alien. However, see Publication 515, Withholding of Tax on Nonresident Aliens and Foreign Entities, for exceptions to this general rule.

Religious exemption.    An exemption from social security and Medicare taxes is available to members of a recognized religious sect opposed to public insurance. This exemption is available only if both the employee and the employer are members of the sect.

  For more information, see Publication 517, Social Security and Other Information for Members of the Clergy and Religious Workers.

5. Federal Income Tax Withholding

Farmers and crew leaders must withhold federal income tax from the wages of farmworkers if the wages are subject to social security and Medicare taxes. The amount to withhold is figured on gross wages before taking out social security and Medicare taxes, union dues, insurance, etc. You may use one of several methods to determine the amount of federal income tax withholding. They are discussed in section 13.

Form W-4.   To know how much federal income tax to withhold from employees' wages, you should have a Form W-4, Employee's Withholding Allowance Certificate, on file for each employee. Encourage your employees to file an updated Form W-4 for 2008, especially if they owed taxes or received a large refund when filing their 2007 tax return. Advise your employees to visit the IRS website at
www.irs.gov/individuals and select the “IRS Withholding Calculator” link for help in determining how many withholding allowances to claim on their Form W-4. Ask each new employee to give you a signed Form W-4 when starting work. Make the form effective with the first wage payment. If a new employee does not give you a completed Form W-4, withhold tax as if he or she is single, with no withholding allowances.

Forms in Spanish.   You can provide Formulario W-4(SP), Certificado de Exención de la Retención del Empleado, in place of Form W-4, Employee's Withholding Allowance Certificate, to your Spanish-speaking employees. For more information, see Publication 579(SP), Cómo Preparar la Declaración de Impuesto Federal.

Effective date of Form W-4.   A Form W-4 remains in effect until the employee gives you a new one. When you receive a new Form W-4, do not adjust withholding for pay periods before the effective date of the new form. Do not adjust withholding retroactively. For exceptions, see Exemption from federal income tax withholding, IRS review of Forms W-4, and Invalid Forms W-4 later. If an employee gives you a replacement Form W-4, begin withholding no later than the start of the first payroll period ending on or after the 30th day from the date when you received the replacement Form W-4.

Caution
A Form W-4 that makes a change for the next calendar year will not take effect in the current calendar year.

Completing Form W-4.   The amount of federal income tax withholding is based on marital status and withholding allowances. Your employees may not base their withholding amounts on a fixed dollar amount or percentage. However, the employee may specify a dollar amount to be withheld in addition to the amount of withholding based on filing status and withholding allowances claimed on Form W-4.

  Employees may claim fewer withholding allowances than they are entitled to claim. They may do this to ensure that they have enough withholding or to offset other sources of taxable income that are not subject to withholding.

  Publication 505, Tax Withholding and Estimated Tax, contains detailed instructions for completing Form W-4. Along with Form W-4, you may wish to order
Publication 505 and Publication 919, How Do I Adjust My Tax Withholding, for your employees.

   Do not accept any withholding or estimated tax payments from your employees in addition to withholding based on their Form W-4. If an employee wants additional withholding, he or she should submit a new Form W-4 and, if necessary, pay estimated tax by filing Form 1040-ES, Estimated Tax for Individuals.

Exemption from federal income tax withholding.   Generally, an employee may claim exemption from federal income tax withholding because he or she had no federal income tax liability last year and expects none this year. See the Form W-4 instructions for more information. However, the wages are still subject to social security and Medicare taxes.

  A Form W-4 claiming exemption from withholding is valid for only one calendar year. To continue to be exempt from withholding in the next year, an employee must give you a new Form W-4 by February 15 of that year. If the employee does not give you a new Form W-4, withhold tax as if the employee is single with zero withholding allowances or withhold based on the last valid Form W-4 you have for the employee.

Procedure for withholding income taxes on the wages of nonresident alien employees.   In general, you must withhold federal income taxes on the wages of nonresident alien employees. However, see Publication 515 for exceptions to this general rule.

  Under this procedure, you add an amount, as set forth in the chart below, to the nonresident alien employee's wages solely for purposes of calculating the federal income tax withholding for each payroll period. You determine the amount to be withheld by applying the federal income tax withholding tables to the amount of wages paid plus the additional chart amount.

  
Tip
Nonresident alien students from India and business apprentices from India are not subject to this procedure.

  The amount to be added to the nonresident alien employee's wages to calculate federal income tax withholding is set forth in the following chart:

Amount to Add to Nonresident Alien Employee's Wages for Calculating Income Tax Withholding Only

Payroll Period Add Additional  
Weekly $51.00  
Biweekly 102.00  
Semimonthly 110.00  
Monthly 221.00  
Quarterly 663.00  
Semiannually 1,325.00  
Annually 2,650.00  
Daily or Miscellaneous
(each day of the payroll period)
10.20  

  The amounts added under this chart for purposes of this procedure are added to wages solely for the purpose of calculating the amount of federal income tax withholding on the wages of the nonresident alien employee. These chart amounts should not be included in any box on the employee's Form W-2 and do not increase the federal income tax liability of the employee. Also, these chart amounts do not increase the social security, Medicare, or FUTA tax liability of the employer or the employee.

  This procedure only applies to nonresident alien employees who have wages subject to federal income tax withholding.

Example.

An employer using the percentage method of withholding pays wages of $500 for a biweekly payroll period to a married nonresident alien employee. The nonresident alien has properly completed Form W-4, entering marital status as single with one withholding allowance and indicating status as a nonresident alien on line 6 of
Form W-4 (see below). The employer determines the wages to be used in the withholding tables by adding to the $500 amount of wages paid the amount of $102 from the chart above ($602 total). The employer then applies the applicable table (Table 2(a), the table for biweekly payroll period, single persons) by subtracting the applicable percentage method amount for one withholding allowance for a biweekly payroll period from $602 and making the calculations under the table.

The $102 added to wages for purposes of calculating income tax withholding is not reported on Form W-2, and does not affect the social security tax, Medicare tax, or FUTA tax liability of the employer or the employee.

Supplemental wage payment.   This procedure for determining the amount of federal income tax withholding does not apply to a supplemental wage payment (see Supplemental wages on page 12) if the 35% mandatory flat rate withholding applies or if the 25% flat rate withholding is being used to calculate income tax withholding on the supplemental wage payment.

Nonresident alien employee's Form W-4.   When completing Forms W-4, nonresident aliens are required to:
  • Not claim exemption from income tax withholding;

  • Request withholding as if they are single, regardless of their actual marital status;

  • Claim only one allowance (if the nonresident alien is a resident of Canada, Mexico, or Korea, he or she may claim more than one allowance); and

  • Write “Nonresident Alien” or “NRA” above the dotted line on line 6 of Form W-4.

  If you maintain an electronic Form W-4 system, you should provide a field for nonresident alien employees to enter nonresident alien status in lieu of writing “Nonresident Alien” or “NRA” above the dotted line on line 6.

  
Tip
Nonresident alien employees are no longer required to request additional withholding in the box for line 6 on Form W-4. However, a nonresident alien employee may request additional withholding at his or her option.

Form 8233.   If a nonresident alien employee claims a tax treaty exemption from withholding, the employee must submit Form 8233, Exemption from Withholding on Compensation for Independent (and Certain Dependent) Personal Services of a Nonresident Alien Individual, with respect to the income exempt under the treaty, instead of Form W-4. See Publication 515 for details.

IRS review of requested Forms W-4.   In the past, you had to routinely send the IRS any Form W-4 claiming complete exemption from withholding if $200 or more in weekly wages was expected or claiming more than 10 allowances. Employers no longer have to submit these Forms W-4 to the IRS. However, Forms W-4 are still subject to review. When we refer to Form W-4, the same rules apply to Formulario W-4(SP), its Spanish translation.

  You may receive a notice from the IRS requiring you to submit copies of Forms W-4. Send the requested copy or copies of Form W-4 to the IRS at the address provided and in the manner directed by the notice. You may also be directed to make available for inspection by an IRS employee certain Forms W-4. The notice you receive from the IRS may relate to one or more of your named employees. IRS may also require you to submit copies of Form W-4 to the IRS as directed by a revenue procedure or notice published in the Internal Revenue Bulletin.

  After submitting a copy of the requested Form W-4 to the IRS, continue to withhold federal income tax based on that Form W-4 if it is valid (see Invalid Forms W-4 later). However, the IRS may later notify you in writing that the employee is not entitled to claim a complete exemption from withholding or more than the maximum number of withholding allowances specified by the IRS in the written notice. The notice will also specify the applicable marital status for purposes of calculating the required amount of withholding. You are to withhold federal income tax based on the effective date shown on the notice using the maximum number of withholding allowances and marital status specified in the notice (commonly referred to as a “lock-in letter”).

Initial lock-in letter.   The IRS uses information reported on Form W-2, Wage and Tax Statement, to identify employees with withholding compliance problems. In some cases, where a serious under-withholding problem is found to exist for a particular employee, the IRS may issue a lock-in letter to the employer specifying the maximum number of withholding allowances and marital status permitted for a specific employee. If the employee is employed by you as of the date of the notice, you must furnish the notice to the employee within 10 business days of receipt. You may follow any reasonable business practice to furnish the copy of the notice to the employee.

Implementation of lock-in letter.   When you receive the notice specifying the maximum number of withholding allowances and marital status permitted, you may not withhold immediately on the basis of the notice. You must begin withholding tax on the basis of the notice for any wages paid after the date specified in the notice. The delay between your receipt of the notice and the date to begin the withholding on the basis of the notice permits the employee to contact the IRS.

Seasonal employees and employees not currently performing services.   If you receive a notice for an employee who is not currently performing services for you, you are still required to furnish the notice to the employee and withhold based on the notice if:
  • You are paying wages for the employee's prior services and the wages are subject to income tax withholding on or after the date specified in the notice.

  • You reasonably expect the employee to resume services within 12 months of the date of the notice.

  • The employee is on a bona fide leave of absence that does not exceed 12 months or the employee has a right to reemployment after the leave of absence.

Termination and re-hire of employees.   If you are required to furnish and withhold based on the notice and the employment relationship is terminated after the date of the notice, you must continue to withhold based on the notice if you continue to pay any wages subject to income tax withholding. You must also withhold based on the notice or modification notice (see Modification notice next) if the employee resumes the employment relationship with you within 12 months after the termination of the employment relationship.

Modification notice.   After issuing the notice specifying the maximum number of withholding allowances and marital status permitted, the IRS may issue a subsequent notice (modification notice) that modifies the original notice. The modification notice may change the marital status and/or the number of withholding allowances permitted. You must withhold federal income tax based on effective date specified in the modification notice.

Employee provides you a new Form W-4 after IRS notice.   After the IRS issues a notice or modification notice, if the employee provides you with a new Form W-4 claiming complete exemption from withholding or claims a marital status, a number of withholding allowances, and any additional withholding that results in less withholding than would result under the IRS notice or modification notice, you must disregard the new Form W-4. You are required to withhold on the basis of the notice or modification notice unless the IRS subsequently notifies you to withhold based on the new Form W-4. If the employee wants to put a new Form W-4 into effect that results in less withholding than required, the employee must contact the IRS.

  If, after you receive an IRS notice or modification notice, your employee provides you with a new Form W-4 that does not claim exemption from federal income tax withholding and claims a marital status, a number of withholding allowances, and any additional withholding that results in more withholding than would result under the notice or modification notice, you must withhold tax on the basis of that new Form W-4. Otherwise, disregard any subsequent Forms W-4 provided by the employee and withhold based on the IRS notice or modification notice.

Substitute Forms W-4.   You are encouraged to have your employees use the official version of Form W-4 to claim withholding allowances or exemption from withholding. Call the IRS at 1-800-829-3676 or visit the IRS website at www.irs.gov to obtain copies of Form W-4.

  You may use a substitute version of Form W-4 to meet your business needs. However, your substitute Form W-4 must contain language that is identical to the official Form W-4 and your form must meet all current IRS rules for substitute forms. At the time that you provide your substitute form to the employee, you must provide him or her with all tables, instructions, and worksheets from the current Form W-4.

  You are prohibited from accepting a substitute Form W-4 developed by an employee, and the employee submitting such form will be treated as failing to furnish a Form W-4. However, continue to use any valid Forms W-4 developed by your employees that you accepted before October 11, 2007.

Invalid Forms W-4.   Any unauthorized change or addition to Form W-4 makes it invalid. This includes taking out any language by which the employee certifies that the form is correct. A Form W-4 is also invalid if, by the date an employee gives it to you, he or she indicates in any way that it is false. An employee who submits a false Form W-4 may be subject to a $500 penalty. You may treat a Form W-4 as invalid if the employee wrote “exempt” on line 7 and also entered a number on line 5 or an amount on line 6.

  When you get an invalid Form W-4, do not use it to figure federal income tax withholding. Tell the employee that it is invalid and ask for another one. If the employee does not give you a valid one, withhold taxes as if the employee was single and claiming no withholding allowances. However, if you have an earlier Form W-4 for this worker that is valid, withhold as you did before.

  For additional information about these rules, see Treasury Decision 9337. You can find Treasury Decision 9337 on page 455 of Internal Revenue Bulletin 2007-35 at www.irs.gov/pub/irs-irbs/irb07-35.pdf.

Amounts exempt from levy on wages, salary, and other income.   If you receive a Notice of Levy on Wages, Salary, and Other Income (Forms 668-(W)(c), 668-W(c)(DO), or 668-W(ICS)), you must withhold amounts as described in the instructions for these forms. Publication 1494 (2008), Table for Figuring Amount Exempt From Levy on Wages, Salary, and Other Income—Forms 668-W(c), 668-W(c)(DO), and 668-W(ICS), shows the exempt amount. If a levy issued in a prior year is still in effect and the taxpayer submits a new Statement of Exemptions and Filing Status, use the current year Publication 1494 to compute the exempt amount.

How To Figure Federal Income Tax Withholding

There are several ways to figure federal income tax withholding.

  • Wage bracket tables. See page 21 for directions on how to use the tables.

  • Percentage method. See page 22 for directions on how to use the percentage method.

  • Alternative formula tables for percentage method withholding. See Publication 15-A.

  • Wage bracket percentage method withholding tables. See Publication 15-A.

  • Other alternative methods. See Publication 15-A.

Employers with automated payroll systems will find the two alternative formula tables and the two alternative wage bracket percentage method tables in Publication 15-A useful.

If an employee wants additional federal tax withheld, have the employee show the extra amount on Form W-4.

Supplemental wages.   Supplemental wages are compensation paid to an employee in addition to the employee's regular wages. They include, but are not limited to, bonuses, commissions, overtime pay, accumulated sick leave, severance pay, awards, prizes, back pay and retroactive pay increases for current employees, and payments for nondeductible moving expenses. Other payments subject to the supplemental wage rules include taxable fringe benefits and expense allowances paid under a nonaccountable plan.

  If you pay supplemental wages with regular wages but do not specify the amount of each, withhold federal income tax as if the total was a single payment for a regular payroll period.

  If you pay supplemental wages separately (or combine them in a single payment and specify the amount of each), the federal income tax withholding method depends partly on whether you withhold federal income tax from your employee's regular wages.
  1. If you withhold federal income tax from an employee's regular wages, you can use one of the following methods for the supplemental wages.

    1. Withhold a flat 25% from each payment.

    2. Add the supplemental and regular wages for the most recent payroll period this year. Then figure the federal income tax withholding as if the total was a single payment. Subtract the tax already withheld from the regular wages. Withhold the remaining tax from the supplemental wages. If there was one or more payments of supplemental wages (after the last payment of regular wages but before the current payment of supplemental wages), aggregate all the payments, calculate the tax on the total, subtract the tax already withheld from the regular wages and the previous supplemental wages, and withhold the remaining tax.

  2. If you did not withhold federal income tax from the employee's regular wages, use method 1b above. This would occur, for example, when the value of the employee's withholding allowances claimed on Form W-4 is more than the wages.

  
Caution
Separate rules apply to any supplemental wages exceeding $1,000,000 that you pay to an individual during the year. See section 7 in
Publication 15 (Circular E) for details.

  Regardless of the method that you use to withhold federal income tax on supplemental wages, they are generally subject to social security, Medicare, and FUTA taxes.

6. Advance Earned Income Credit (EIC) Payment

An employee who expects to be eligible for the earned income credit (EIC) and who expects to have a qualifying child is entitled to receive EIC payments with his or her pay during the year. To get these payments, the employee must give you a properly completed Form W-5 (or Formulario W-5(SP), its Spanish translation), Earned Income Credit Advance Payment Certificate, using either the paper form or the approved electronic format. You are required to make advance EIC payments to employees who give you a properly completed Form W-5; except that you are not required to make these payments to farmworkers paid on a daily basis.

Certain employees who do not have a qualifying child may be able to claim the EIC on their tax return. However, they cannot get advance EIC payments.

For 2008, the advance payment can be as much as $1,750. The tables that begin on page 47 reflect that limit.

Form W-5.   Form W-5 explains the eligibility requirements for receiving advance EIC payments. On Form W-5, an employee states that he or she expects to be eligible to claim the EIC and shows whether he or she has another Form W-5 in effect with any other current employer.

  You must include advance EIC payments with the wages that you pay to eligible employees who give you a signed and completed Form W-5. Form W-5 is effective for the first payroll period ending (or the first wage payment made without regard to a payroll period) on or after the date the employee gives you the form. It remains in effect until the end of the year or until the employee revokes it or gives you a new one. Employees must give you a new Form W-5 each year.

  An employee may have only one Form W-5 in effect with a current employer at one time. If an employee is married and his or her spouse also works, each spouse should file a separate Form W-5.

  For more information, see Form W-5 or Publication 15 (Circular E).

How to figure the advance EIC payment.   Figure the amount of advance EIC to include in the employee's pay by using either the wage bracket or percentage method tables that begin on page 47. There are separate tables for employees whose spouses have a Form W-5 in effect.

  
Caution
During 2008, if you pay an employee total wages of at least $33,995 ($36,995 if married filing jointly) you must stop making advance EIC payments to that employee for the rest of the year.

Paying the advance EIC to employees.   Advance EIC payments are not subject to withholding of income, social security, or Medicare taxes. An advance EIC payment does not change the amount of income, social security, or Medicare taxes that you withhold from the employee's wages. You add the advance EIC payment to the employee's net pay for the pay period. At the end of the year, you show the total advance EIC payments in box 9 on Form W-2. Do not include this amount as wages in box 1.

Employer's returns.   Show the total payments that you made to employees on the advance EIC line (line 10) of your Form 943. Subtract this amount from your total taxes on line 9. See the Instructions for Form 943. Reduce the amounts reported on line 15 of Form 943 or on
Form 943-A, Agricultural Employer's Record of Federal Tax Liability, by any advance EIC paid to your employees.

  Generally, you will make the advance EIC payment from withheld federal income tax and employee and employer social security and Medicare taxes. Advance EIC payments are treated as deposits of these taxes on the day that you pay wages (including the advance EIC payment) to your employees. The payments are treated as deposits of these taxes in the following order: first to the amount of federal income tax withholding, then to withheld employee social security and Medicare taxes, and last, to the employer's share of social security and Medicare taxes. For more information, see Publication 15 (Circular E).

Required Notice to Employees

You must notify employees who have no federal income tax withheld that they may be able to claim a tax refund because of the EIC. Although you do not have to notify employees who claim exemption from withholding on Form W-4, Employee's Withholding Allowance Certificate, about the EIC, you are encouraged to notify any employees whose wages for 2007 were less than $37,783 ($39,783 if married filing jointly) that they may be eligible to claim the credit for 2007. This is because eligible employees may get a refund of the amount of EIC that is more than the tax that they owe.

You will meet the notification requirement if you issue to the employee Form W-2 with the EIC notice on the back of Copy B, or a substitute Form W-2 with the same statement. You may also meet the requirement by providing Notice 797, Possible Federal Tax Refund Due to the Earned Income Credit (EIC), or your own statement that contains the same wording.

If a substitute Form W-2 is given to the employee on time but does not have the required statement, you must notify the employee within 1 week of the date that the substitute Form W-2 is given. If Form W-2 is required but is not given on time, you must give the employee Notice 797 or your written statement by the date that Form W-2 is required to be given. If Form W-2 is not required, you must notify the employee by February 7, 2008.

7. Depositing Taxes

Generally, you must deposit both the employer and employee shares of social security and Medicare taxes and federal income tax withheld (minus any advance earned income credit payments). You must deposit by using the Electronic Federal Tax Payment System (EFTPS) or by mailing or delivering a check, money order, or cash with Form 8109, Federal Tax Deposit Coupon, to an authorized financial institution that is an authorized depositary for federal taxes. However, some employers must only deposit using EFTPS. See How To Deposit on page 15.

Payment with return.   You may make payments with Forms 943 or 945 instead of depositing if one of the following applies.
  • You report less than a $2,500 tax liability for the year (line 11 of Form 943 or line 4 of Form 945) and you pay in full with a return that is filed on time. However, if you are unsure that you will report less than $2,500, deposit under the rules explained in this section so that you will not be subject to failure-to-deposit penalties.

  • You are a monthly schedule depositor and make a payment in accordance with the Accuracy of Deposits Rule discussed later. This payment may be $2,500 or more.

Caution
Only monthly schedule depositors, defined later, are allowed to make an Accuracy of Deposits Rule payment with the return. Semiweekly schedule depositors must timely deposit the amount. See Accuracy of Deposits Rule and How To Deposit later in this section.

When To Deposit

Caution
If you employ both farm and nonfarm workers, do not combine the taxes reportable on Forms 941 or 944 with Form 943 to decide whether to make a deposit. See Employers of Both Farm and Nonfarm Workers on page 18.

The rules for determining when to deposit Form 943 taxes are discussed below. (Separate rules apply to federal unemployment (FUTA) tax. See section 10.) Under these rules, you are classified as either a monthly schedule depositor or a semiweekly schedule depositor.

The terms “monthly schedule depositor” and “semiweekly schedule depositor” do not refer to how often your business pays its employees or how often you are required to make deposits. The terms identify which set of rules you must follow when you incur a tax liability.

The deposit schedule that you must use for a calendar year is determined from the total taxes (not reduced by any advance EIC payments) reported on your Form 943 (line 9) for the lookback period, discussed next.

  • If you reported $50,000 or less of Form 943 taxes for the lookback period, you are a monthly schedule depositor.

  • If you reported more than $50,000 of Form 943 taxes for the lookback period, you are a semiweekly schedule depositor.

Lookback period.   The lookback period is the second calendar year preceding the current calendar year. For example, the lookback period for 2008 is 2006.

Example of deposit schedule based on lookback period.

Rose Co. reported taxes on Form 943 as follows.

2006 — $48,000
2007 — $60,000

Rose Co. is a monthly schedule depositor for 2008 because its taxes for the lookback period ($48,000 for calendar year 2006) were not more than $50,000. However, for 2009, Rose Co. is a semiweekly schedule depositor because the total taxes for its lookback period ($60,000 for calendar year 2007) exceeded $50,000.

Adjustments to lookback period taxes.   To determine your taxes for the lookback period, use only the tax that you reported on the original return (Form 943, line 9). Do not include adjustments made on a supplemental return filed after the due date of the return. However, if you make adjustments on Form 943, the adjustments are included in the total tax for the period in which the adjustments are reported.

Example of adjustments.

An employer originally reported total tax of $45,000 for the lookback period in 2006. The employer discovered during March 2007 that the tax during the lookback period was understated by $10,000 and corrected this error with an adjustment on the 2007 Form 943. The total tax reported in the lookback period is still $45,000. The $10,000 adjustment is treated as part of the 2007 taxes.

Deposit period.   The term “deposit period” refers to the period during which tax liabilities are accumulated for each required deposit due date. For monthly schedule depositors, the deposit period is a calendar month. The deposit periods for semiweekly schedule depositors are Wednesday through Friday and Saturday through Tuesday.

Monthly Deposit Schedule

If the total tax reported on line 9 of Form 943 for the lookback period is $50,000 or less, you are a monthly schedule depositor for the current year. You must deposit Form 943 taxes on payments made during a calendar month by the 15th day of the following month.

Monthly schedule example.   Red Co. is a seasonal employer and a monthly schedule depositor. It pays wages each Friday. It paid wages during August 2008, but did not pay any wages during September. Red Co. must deposit the combined tax liabilities for the August paydays by September 15. Red Co. does not have a deposit requirement for September (that is, due by October 15) because no wages were paid in September; therefore, it did not have a tax liability for September.

New employers.   For agricultural employers, your tax liability for any year in the lookback period before the date you started or acquired your business is considered to be zero. Therefore, you are a monthly schedule depositor for the first and second calendar years of your agricultural business (but see the $100,000 Next-Day Deposit Rule on page 15).

Semiweekly Deposit Schedule

You are a semiweekly schedule depositor for a calendar year if the total taxes on line 9 of Form 943 during your lookback period were more than $50,000. Under the semiweekly deposit schedule, deposit Form 943 taxes for payments made on Wednesday, Thursday, and/or Friday by the following Wednesday. Deposit amounts accumulated for payments made on Saturday, Sunday, Monday, and/or Tuesday by the following Friday.

Semiweekly depositors are not required to deposit twice a week if their payments were in same semiweekly period unless the $100,000 Next Day Deposit Rule (discussed later) applies. For example, if you made a payment on both Wednesday and Friday and incurred taxes of $10,000 for each pay date, deposit the $20,000 by the following Wednesday. If you made no additional payments on Saturday through Tuesday, no deposit is due on Friday.

Caution
Semiweekly schedule depositors must complete Form 943-A and submit it with Form 943.

Semiweekly Deposit Schedule

IF the payday falls on a... THEN deposit taxes by
the following...
Wednesday, Thursday, and/or Friday Wednesday
Saturday, Sunday, Monday, and/or Tuesday Friday

Semiweekly schedule example.   Green, Inc., a semiweekly schedule depositor, pays wages on the last day of each month. Green, Inc., will deposit only once a month, but the deposit will be made under the semiweekly deposit schedule as follows. Green, Inc.'s tax liability for the
May 31, 2008 (Saturday), wage payment must be deposited by June 6, 2008 (Friday).

Semiweekly deposit period spanning two quarters.   If you have more than one pay date during a semiweekly period and the pay dates fall in different calendar quarters, you will need to make separate deposits for the separate liabilities. For example, if you have a pay date on Saturday, March 29, 2008 (first quarter), and another pay date on Tuesday, April 1, 2008 (second quarter), two separate deposits will be required even though the pay dates fall within the same semiweekly period. Both deposits will be due Friday, April 4, 2008 (three banking days from the end of the semiweekly deposit period).

Deposits on Banking Days Only

If a deposit is required to be made on a day that is not a banking day, the deposit is considered on time if it is made by the next banking day. In addition to federal and state bank holidays, Saturdays and Sundays are treated as nonbanking days. For example, if a deposit is required to be made on Friday, but Friday is not a banking day, the deposit is considered timely if it is made by the following Monday (if Monday is a banking day).

Semiweekly schedule depositors   will always have 3 banking days to make a deposit. That is, if any of the 3 weekdays after the end of a semiweekly period is a banking holiday, you will have 1 additional banking day to deposit. For example, if a semiweekly schedule depositor accumulated taxes on Friday and the following Monday is not a banking day, the deposit normally due on Wednesday may be made on Thursday (allowing 3 banking days to make the deposit).

$100,000 Next-Day Deposit Rule

If you accumulate $100,000 or more of Form 943 taxes (that is, taxes
