How to Fill Out IRS Form 7204: Contested Tax and Consent to Extend

IRS Form 7204 is a short consent form you attach to your return to claim a provisional foreign tax credit for a contested foreign income tax you have already paid. To fill out IRS Form 7204, enter your identifying information and basis of accounting at the top, fill in the applicable tax year in item 1, complete the five sub-parts of item 6 describing the contested tax, sign under the rules for your taxpayer type, and file it with Form 1116 or Form 1118 for the correct year. Items 2 through 5 are pre-printed legal provisions you agree to by signing; you do not write in them.¹

Before You Start: Confirm Basis and Year

Two threshold questions decide what you write on the form and where it goes.

First, confirm the underlying foreign tax is creditable. Form 7204 changes only the timing of when you can claim a credit while a dispute is pending; it does not rescue a tax that fails the ordinary creditability rules under Treasury Regulation section 1.901-2.²³

Second, identify whether you claim the foreign tax credit on an accrual basis or a cash basis. The choice controls the tax year you enter on the form and the return it rides with:

Accrual basis: use the U.S. tax year to which the contested foreign income tax relates (the relation-back year). File Form 7204 with an original or amended Form 1116 or Form 1118 for that year.
Cash basis: use the U.S. tax year in which you actually remitted the contested tax. File Form 7204 with the Form 1116 or Form 1118 for the remittance year.

Accrual-basis filers often end up amending a prior-year return to add the election. Cash-basis filers usually attach the form to the original return for the year of payment.⁴

Top of the Form: Name, Number, and Basis

Enter your name and address as they appear on the return you are attaching the form to. For the identifying number, individuals use a Social Security number; corporations, estates, and trusts use an employer identification number. Check the box that shows whether you claim the credit on the accrual basis or the cash basis.⁴

Item 1: Tax Year

Item 1 contains pre-printed consent language that references “the tax year ended.” Fill in the applicable tax year end date. Accrual-basis filers write the end of the relation-back year. Cash-basis filers write the end of the year in which the contested tax was remitted.⁴

Item 6: Describing the Contested Tax

Item 6 is the substantive part of the form and has five sub-parts.

Line 6a — Nature of the Contest

Describe the dispute. The instructions call for three pieces: the nature of the contest (for example, a foreign-initiated transfer pricing audit), the type of foreign tax at issue (for example, a nonresident corporate income tax), and the venue where the contest is being pursued (appeals, court, or competent authority).⁴

Line 6b — Payor

Enter the name and EIN or reference ID number of the entity that actually remitted the contested tax to the foreign country. The payor can be you, a qualified business unit, a controlled foreign corporation, or a QBU of such a CFC.⁴

Line 6c — Reference ID Number

Create a 12-character alphanumeric reference ID for the contested tax. No spaces or special characters. Build it in this order:

Characters 1–4: the year from your line 1 tax year end.
Characters 5–6: the month from your line 1 tax year end.
Characters 7–8: the two-letter country code (available at IRS.gov/CountryCodes).
Characters 9–12: your own identifier for the specific contested tax.

Line 6d — Country Code

Enter the two-letter code for the country or U.S. territory to which you remitted the contested tax.⁴

Line 6e — Amount and Dates

List the amount of contested tax remitted in the local currency of the foreign country, along with the date or dates of each remittance.⁴

What You Agree to by Signing (Items 2 Through 5)

You do not write anything in items 2 through 5. They are pre-printed provisions that become binding when you sign. In plain terms:

Item 1’s consent language extends the IRS’s assessment period for any federal income tax related to the contested credit. The window stays open until three years after the later of the filing date or due date, with extensions, of the return for the tax year in which you notify the IRS that the contest has been resolved.⁵
Item 2 commits you to the annual notice requirement, meaning a Schedule C (Form 1116) or Schedule L (Form 1118) every year until the contest resolves.
Item 3 says the consent can be suspended or extended by operation of law like the regular assessment period, and cannot shorten the time the IRS already has.
Item 4 preserves your right to file a refund claim within six months after the extended assessment period ends or within the period prescribed by Section 6511(d)(3)(A), whichever is later.
Item 5 limits any deficiency assessment to federal income tax arising from a determination that the contested tax was not a compulsory payment under Regulations section 1.901-2(e)(5), plus related penalties, interest, and consequential adjustments.⁵

Signing the Form

Because Form 7204 is a binding consent, the signature rules are specific to taxpayer type:

Joint returns: both spouses sign unless one holds a power of attorney and signs as agent for the other.
Corporations: a responsible officer signs and shows the title. For consolidated return filers, the common parent generally signs as agent for subsidiaries under Regulations section 1.1502-77.
Attorney or agent: an attorney or agent may sign only if specifically authorized on Form 2848. Attach a copy of the Form 2848 to the Form 7204.
Fiduciaries: a trustee attaches a copy of Form 56 and the trust instrument. An executor or administrator attaches Form 56 plus a certified copy of letters testamentary or a court certificate showing the current status of the estate.
Bankruptcy: the bankruptcy trustee signs if the trustee has possession of, or title to, substantially all of the corporation’s property or business.

An unsigned or improperly signed form can invalidate the election. If the IRS treats the consent as invalid, it can disallow the provisional credit, which may leave you owing additional tax, interest, and a 20-percent accuracy-related penalty under Section 6662.⁴⁶

Filing the Completed Form

Attach the signed Form 7204 to your income tax return for the applicable year. Individuals include it with Form 1040 and Form 1116. Corporations attach it to Form 1120 and Form 1118. The form and the foreign tax credit schedule travel together; sending one without the other creates an incomplete election.⁴

Accrual-basis filers claiming the provisional credit for a prior year will usually attach Form 7204 to an amended return, such as Form 1040-X for individuals. Amended returns for the current or two prior tax periods can be e-filed; older years require paper filing.⁷ Cash-basis filers usually attach the form to the original return for the year of remittance.

Keep a copy of the filed return and proof of acceptance. The consent takes effect when the IRS processes the return, and you may need the filing date later if the assessment period is questioned.

What You Owe After Filing

The election is not a one-time filing. From the year after you make it through the year the contest is resolved, you must file Schedule C (Form 1116) or Schedule L (Form 1118) with each year’s return to satisfy the annual notice requirement under Regulations section 1.905-1(d)(4)(iv).⁴ Missing a year can jeopardize the election.

Once the foreign tax dispute is settled, notify the IRS on the return for the tax year in which the resolution occurs. If the foreign country refunds part or all of the contested tax, you have a foreign tax redetermination and must adjust the previously claimed credit; Publication 514 covers that process for individuals.⁸⁵
