taxes owed on this return, and the financial institution to debit the entry to this account. To revoke a payment, I must 

contact the U.S. Treasury Financial Agent at 1-888-353-4537 no later than 2 business days prior to the payment

the corporation will remain liable for the tax liability and all applicable interest and penalties.

Under penalties of perjury, I declare that I am an officer of the above corporation and that the information I have given my electronic return originator (ERO), 

transmitter, and/or intermediate service provider (ISP) and the amounts in Part I above agree with the amounts on the corresponding lines of the corporation’s 

2011 federal income tax return. To the best of my knowledge and belief, the corporation’s return is true, correct, and complete. I consent to my ERO, transmitter, 

and/or ISP sending the corporation’s return, this declaration, and accompanying schedules and statements to the IRS. I also consent to the IRS sending my 

ERO, transmitter, and/or ISP an acknowledgement of receipt of transmission and an indication of whether or not the corporation’s return is accepted and, if 

rejected, the reason(s) for the rejection. If the processing of the corporation’s return or refund is delayed, I authorize the IRS to disclose to my ERO, transmitter, 

and/or ISP the reason(s) for the delay, or when the refund was sent.

General Instructions

TIP

Instead of filing Form 8453-S, a 

corporate officer filing a 

corporation’s return through an 

electronic return originator 

(ERO) can sign the return using a personal 

identification number (PIN). For details, see 

Form 8879-S, IRS e-file Signature 

Authorization for Form 1120S.

Purpose of Form

Use Form 8453-S to:

• Authenticate an electronic Form 1120S, 

U.S. Income Tax Return for an S Corporation,

• Authorize the ERO, if any, to transmit via 

a third-party transmitter,

• Authorize the intermediate service 

provider (ISP) to transmit via a third-party 

transmitter if you are filing online (not using 

an ERO), and

• Provide the corporation’s consent to 

directly deposit any refund and/or 

authorize an electronic funds withdrawal 

for payment of federal taxes owed.

Who Must File

If you are filing a 2011 Form 1120S through 

an ISP and/or transmitter and you are not 

using an ERO, you must file Form 8453-S 

with your electronically filed return. An ERO 

can use either Form 8453-S or Form 

8879-S to obtain authorization to file the 

corporation’s Form 1120S.

When and Where To File

File Form 8453-S with the corporation’s 

electronically filed income tax return. Use a 

scanner to create a Portable Document File 

(PDF) file of the completed form. Your tax 

preparation software will allow you to 

transmit this PDF file with the return.

Specific Instructions

Name. Print or type the corporation’s

name in the space provided.

Employer identification number (EIN). 

Enter the corporation’s EIN in the space

provided.

Part II—Declaration of 

Officer

Note. The corporate officer must check all 

applicable boxes on line 6.

If the corporation has tax due and the 

officer did not check box 6c, the 

corporation must deposit the payment no 

later than the 15th day of the 3rd month 

after the end of its tax year. For more 

information, see the Instructions for Form 

1120S.

If the officer checks box 6c, the officer 

must ensure that the following information 

relating to the financial institution account 

is provided in the tax preparation software.

• Routing number.

• Account number.

• Type of account (checking or savings).

• Debit amount.

• Debit date (date the corporation wants 

the debit to occur).

An electronically transmitted return will 

not be considered complete, and therefore 

filed, unless either:

• Form 8453-S is signed by a corporate 

officer, scanned into a PDF file, and 

transmitted with the return, or

• The return is filed through an ERO and 

Form 8879-S is used to select a PIN that is 

used to electronically sign the return.

The officer’s signature allows the IRS to 

disclose to the ERO, transmitter, and/or 

ISP:

• An acknowledgement that the IRS has 

accepted the corporation’s electronically 

filed return, and

• The reason(s) for any delay in processing 

the return or refund.

The declaration of officer must be signed 

and dated by:

• The president, vice president, treasurer, 

assistant treasurer, chief accounting 

officer, or

• Any other corporate officer (such as tax 

officer) authorized to sign the corporation’s 

income tax return.

If the ERO makes changes to the 

electronic return after Form 8453-S has 

been signed by the officer, whether it was 

before it was transmitted or if the return 

was rejected after transmission, the ERO 

must have the officer complete and sign a 

corrected Form 8453-S if either:

• The total income (loss) on Form 1120S, 

line 6, differs from the amount on the 

electronic return by more than $150, or

• The ordinary business income (loss) on 

Form 1120S, line 21, differs from the 

amount on the electronic return by more 

than $100.

Part III—Declaration of 

Electronic Return Originator 

(ERO) and Paid Preparer

Note. If the return is filed online through an 

ISP and/or transmitter (not using an ERO), 

do not complete Part III.

If the corporation’s return is filed through 

an ERO, the IRS requires the ERO’s 

signature. A paid preparer, if any, must 

sign Form 8453-S in the space for Paid 

Preparer Use Only. But if the paid preparer 

is also the ERO, do not complete the paid 

preparer section. Instead, check the box 

labeled “Check if also paid preparer.” 

Refunds. After the IRS has accepted the

return, the refund should be issued within 3 

weeks. However, some refunds may be 

delayed because of compliance reviews to 

ensure that returns are accurate.

Use of PTIN

Paid preparers. Anyone who is paid to 

prepare the corporation's return must enter 

their PTIN in Part III. The PTIN entered 

must have been issued after September 

27, 2010. For information on applying for 

and receiving a PTIN, see Form W-12, IRS 

Paid Preparer Tax Identification Number 

(PTIN) Application and Renewal, or visit 

www.irs.gov/ptin.

EROs who are not paid preparers. Only 

EROs who are not also the paid preparer of 

the return have the option to enter their 

PTIN or their social security number in the 

"ERO's Use Only" section of Part III. If the 

PTIN is entered, it must have been issued 

after September 27, 2010. For information 

on applying for and receiving a PTIN, see 

Form W-12, IRS Paid Preparer Tax 

Identification Number (PTIN) Application 

and Renewal, or visit www.irs.gov/ptin.
