If you go out of business or end operations and you will not have to file Form 945 in the future, file a final return. Be sure to check the box on line A and enter the date that final nonpayroll payments were made.

Enter the federal income tax that you withheld (or were required to withhold) from pensions (including distributions from tax-favored retirement plans, for example, section 401(k), section 403(b), and governmental section 457(b) plans), annuities, IRA distributions, military retirement, Indian gaming profits, and gambling winnings (regular gambling withholding only). Also enter any voluntary amount that you withheld on certain government payments. If you are required to report federal income tax withholding on Forms 1099 (for example, Form 1099-R or 1099-MISC) or Form W-2G, you must report the federal income tax withheld on 
Form 945.

  

Federal income tax withholding reported on Form W-2 must be reported on Form 941, Form 943, Form 944, or Schedule H (Form 1040), as appropriate.

Enter any backup withholding, including backup withholding on gambling winnings.

Regulated investment companies (RICs) and real estate investment trusts (REITs) must report any backup withholding on Form 945 in the year that the dividends are actually paid. This includes January payments of dividends declared during October, November, and December of the prior year. See the Instructions for Form 1099-DIV for special reporting requirements.

Add lines 1 and 2. If total taxes are $2,500 or more, the amount reported on line 3 must equal the total liability for the year reported on line 7M of the Monthly Summary of Federal Tax Liability, or line M of Form 945-A, Annual Return of Federal Tax Liability.

Enter your total Form 945 deposits for the year, including any overpayment that you applied from filing Form 945-X and any overpayment that you applied from your 2011 return.

If line 3 is more than line 4, enter the difference on line 5. Otherwise, see Overpayment below. You do not have to pay if line 5 is under $1. Generally, you should have a balance due only if your total taxes for the year (line 3) are less than $2,500. If you made payments under the accuracy of deposits rule, see section 11 of Pub. 15 (Circular E).

You may pay the amount shown on line 5 using EFTPS, a credit or debit card, or a check or money order. Do not use a credit or debit card to pay taxes that were required to be deposited. For more information on electronic payment options, visit the IRS website at www.irs.gov/e-pay.

If you pay by EFTPS or credit or debit card, file your return using the Without a payment address under Where To File, earlier. Do not file Form 945-V, Payment Voucher. If you pay by check or money order, make it payable to the “United States Treasury.” Enter your EIN, Form 945, and the tax period on your check or money order. Complete Form 945-V and enclose with Form 945.

If line 3 is $2,500 or more and you deposited all taxes when due, the amount on line 5 should be zero.

If line 4 is more than line 3, enter the difference on line 6. Never make an entry on both lines 5 and 6.

If you deposited more than the correct amount for the year, you can have the overpayment refunded or applied to your next return by checking the appropriate box. Check only one box below line 6. If you do not check either box or if you check both boxes, generally we will apply the overpayment to your account. We may apply your overpayment to any past due tax account that is shown in our records under your EIN. If line 6 is under $1, we will send a refund or apply it to your next return only on written request.

This is a summary of your monthly tax liability, not a summary of deposits made. If line 3 is less than $2,500, do not complete line 7 or Form 945-A.

Complete line 7 only if you were a monthly schedule depositor for the entire year and line 3 is $2,500 or more. See Determining Your Deposit Schedule, earlier.

The amount entered on line 7M must equal the amount reported on line 3.

Report your liabilities on Form 945-A instead of on 
line 7 if either of the following apply.

If you want to allow any individual, corporation, firm, organization, or partnership to discuss your 2012 Form 945 with the IRS, check the “Yes” box in the “Third-Party Designee” section of Form 945. Also, enter the name, phone number, and any five-digit personal identification number (PIN) for the specific person to speak with — not the name of the firm who prepared your return.

By checking the “Yes” box, you are authorizing the IRS to speak with the designee to answer any questions relating to the information reported on your tax return. You are also authorizing the designee to:

You are not authorizing the designee to receive any refund check, bind you to anything (including additional tax liability), or otherwise represent you before the IRS. If you want to expand the designee's authorization, see Pub. 947, Practice Before the IRS and Power of Attorney.

The authorization will automatically expire 1 year from the due date (without regard to extensions) for filing your 2012 Form 945. If you or your designee wants to terminate the authorization, write to the IRS office for your locality using Without a payment address under Where To File, earlier.

Form 945 must be signed as follows:

Form 945 may also be signed by a duly authorized agent of the taxpayer if a valid power of attorney has been filed.

Alternative signature method.   Corporate officers or duly authorized agents may sign Form 945 by rubber stamp, mechanical device, or computer software program. For details and required documentation, see Rev. Proc. 2005-39, 2005-28 I.R.B. 82, available at 
www.irs.gov/irb/2005-28_IRB/ar16.html.

A paid preparer must sign Form 945 and provide the information in the Paid Preparer Use Only section if the preparer was paid to prepare Form 945 and is not 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 are 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, IRS Paid Preparer Tax Identification Number (PTIN) Application and Renewal. For more information about applying for a PTIN online, visit the IRS website at www.irs.gov/ptin. You cannot use your PTIN in place of the EIN of the tax preparation firm.

Generally, do not complete this section if you are filing the return as a reporting agent and have a valid Form 8655, Reporting Agent Authorization, 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 federal income tax withholding is required on certain payments.
