Refund of $1 Million or More, that will be electronically transmitted with the corporation’s 2021 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 2021 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

Note: Instead of filing Form 8453-I, 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-I, IRS e-file Signature 

Authorization for Form 1120-F.

Future Developments

For the latest information about developments related to Form 

8453-I and its instructions, such as legislation enacted after they 

were published, go to www.irs.gov/Form8453I.

Purpose of Form

Use Form 8453-I to:

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

Return of a Foreign 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 2021 Form 1120-F through an ISP and/or 

transmitter and you are not using an ERO, you must file Form 

8453-I with your electronically filed return. An ERO can use 

either Form 8453-I or Form 8879-I to obtain authorization to file 

a corporation’s Form 1120-F.

When and Where To File

File Form 8453-I with the corporation’s electronically filed 

income tax return. Use a scanner to create a Portable 

Document Format (PDF) of the completed form. Your tax 

preparation software will allow you to transmit this PDF 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 rules for payment of the tax due depend on 

whether the corporation maintains an office or place of business 

in the United States. See Payment of Tax Due in the Instructions 

for Form 1120-F for these rules.

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-I 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-I 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 acknowledgment 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-I 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-I if either:

• The total income on Form 1120-F, Section II, line 11, differs 

from the amount on the electronic return by more than 

$150; or

• The taxable income on Form 1120-F, Section II, line 31, 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-I 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. 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. 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.
