6 a I consent that the corporation’s refund be directly deposited as designated on the Form 8050, Direct Deposit of 

Corporate Tax Refund, that will be electronically transmitted with the corporation’s 2012 federal income tax return. 

b I do not want direct deposit of the corporation’s refund or the corporation is not receiving a refund. 

c I authorize the U.S. Treasury and its designated Financial Agent to initiate an electronic funds withdrawal (direct debit) 

entry to the financial institution account indicated in the tax preparation software for payment of the corporation’s federal 

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 

(settlement) date. I also authorize the financial institutions involved in the processing of the electronic payment of taxes 

to receive confidential information necessary to answer inquiries and resolve issues related to the payment. 

If the corporation is filing a balance due return, I understand that if the IRS does not receive full and timely payment of its tax 

liability, 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 2012 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 

acknowledgment 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-C, 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-C, IRS e-file 

Signature Authorization for Form 1120. 

Purpose of Form 

Use Form 8453-C to: 

• Authenticate an electronic Form 1120, U.S. Corporation Income Tax 

Return, 

• 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 2012 Form 1120 through an ISP and/or transmitter and 

you are not using an ERO, you must file Form 8453-C with your 

electronically filed return. An ERO can use either Form 8453-C or Form 

8879-C to obtain authorization to file a corporation’s Form 1120. 

When and Where To File 

File Form 8453-C with the corporation’s electronically filed income tax 

return. Use a scanner to create a Portable Document Format (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 (line 4) 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 on 

depositing taxes, see the Instructions for Form 1120. 

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-C 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-C 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-C 

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-C if either: 

• The total income on Form 1120, line 11, differs from the amount on 

the electronic return by more than $150, or 

• The taxable income on Form 1120, line 30, 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-C 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.” 

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.

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.
