Form 720-X: Amended Quarterly Federal Excise Tax Return

Form 720-X, Amended Quarterly Federal Excise Tax Return, is used to make adjustments to liability reported on Forms 720 filed for previous quarters. The form itself says "Use to correct a previously filed Form 720."

It is not used to change claims made on Schedule C (Form 720), except for the section 4051(d) tire credit and section 6426 credits. The instructions also say a remittance transfer provider (RTP) may use it to correct transcription or calculation errors on a previously filed Form 720, but not to claim amounts for a cancelled or expired remittance transfer.

The result of the adjustments is either a balance due, paid with the return, or an overpayment that is refunded or applied to the next Form 720. This page covers the Rev. June 2026 form. You can fill out the PDF free in your browser on this page and download it without an account.

How to fill out Form 720-X

  1. 1

    Line 1, column (a)

    Report each adjustment separately. Enter the quarter ending date of the Form 720 being amended in MMDDYYYY format. The instructions give 03312026 for the first quarter of 2026.

  2. 2

    Line 1, columns (d) to (f)

    Enter the tax as originally reported or as later adjusted, then the adjusted tax. If (e) is greater, the change is an increase. If (d) is greater, it is a decrease, shown in parentheses.

  3. 3

    Line 2

    Use it for tire credit adjustments with CRN 366. The instructions say section 6426 credits for biodiesel, renewable diesel, alternative fuel and mixtures expired after 2024, and the SAF credit after September 30, 2025.

  4. 4

    Line 3

    For a tax decrease, check the statement that applies: 3a for regular method collectors of IRS Nos. 22, 26, 28 or 27, or 3b for other IRS Nos. not excluded on the form.

  5. 5

    Lines 4 and 5

    Combine column (f) amounts on line 4. For a balance due, enclose a check or money order payable to "United States Treasury" with "Form 720-X", name, address, EIN and date signed written on it. For an overpayment, check 5a to refund or 5b to apply it.

  6. 6

    Line 6 and sign

    Give a detailed description and computation of each adjustment, on line 6 or attached sheets with name and EIN. The instructions say Form 720-X is signed even when filed with Form 720 to apply an overpayment.

Where to send it, time limits and refunds

Where to send

Filed separately, the instructions list Department of the Treasury, Internal Revenue Service, Cincinnati, OH 45999-0009. Otherwise it is attached to the next Form 720.

Time limit for decreases

The instructions say adjustments that decrease tax liability for a prior quarter are generally made within 3 years from the time the return was filed or 2 years from the time the tax was paid, whichever is later.

Applying an overpayment

If box 5b is checked, the overpayment is also included on lines 6 and 7 of the next Form 720. The instructions say it is first applied to any other federal tax, interest or penalty owed.

Direct deposit

Lines 5c to 5e were added for direct deposit of overpayments, but the instructions say the functionality is not yet available. See IRS.gov/Form720X for updates.

Income tax effect

The instructions say an overpayment from line 4 is included in gross income if a deduction on the income tax return included those taxes and reduced the income tax liability.

Private delivery services

Designated private delivery services can be used for the timely mailing rule, but the instructions say they cannot deliver to P.O. boxes.
