Beginning January 1, 2011, the IRS will use business days to determine the timeliness of deposits. Business days are any day that is not a Saturday, Sunday, or legal holiday in the District of Columbia. Legal holidays in the District of Columbia for 2011 are listed below.

To provide transitional relief for 2011, the IRS will not assert penalties for federal tax deposits due during calendar year 2011 that are untimely solely because the depositor treated a statewide legal holiday as if it were a legal holiday in the District of Columbia. See Notice 2010-87, 2010-52 I.R.B. 908, available at www.irs.gov/irb/2010-52_IRB/ar12.html.

If you made your deposits by electronic funds transfers in a state other than that shown in your address on Form 945, enter the state code for the state where you initiated the electronic funds transfers in the box provided in the upper-left corner of Form 945. Use the two-letter U.S. Postal Service state abbreviation as the state code. Enter the code “MU” in the state code box if you deposit in more than one state. If you deposit in the same state as shown in your address, do not make an entry in this box. If you receive a notice because you treated a statewide legal holiday as if it were a legal holiday in the District of Columbia, respond to the notice citing the statewide legal holiday and applicable deposit amount.

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.

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.

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 2010 return.

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). Enter your EIN, “Form 945,” and “2011” on your check or money order and make it payable to the “United States Treasury.” Complete Form 945-V, Payment Voucher, if you are making a payment 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 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. The IRS may apply your overpayment to any past due tax account 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.

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.

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 2011 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 2011 Form 945. If you or your designee wants to terminate the authorization, write to the IRS office for your locality using the address for Where to File (Without a payment), in the chart 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.

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.
