The quarterly federal excise tax return is Form 720, the return a business uses to report its liability by IRS number and pay the federal excise taxes listed on the form (IRS, Instructions for Form 720, Rev. June 2026). It is not one tax with one rate. Each excise tax carries its own IRS number on the form, so a filer reports only the numbers that apply to it and leaves the rest alone.
Where a liability is reported in Part I or Part II, the filer may be eligible to use Schedule C to claim a credit (IRS, Instructions for Form 720), so the same return can carry both what is owed and what is being claimed back.
Who Has to File One
The test is liability or collection responsibility, and it looks backward as well as forward. Form 720 must be filed if you were liable for, or responsible for collecting, any of the federal excise taxes listed in Parts I and II for a prior quarter and you have not filed a final return, or if you are liable for, or responsible for collecting, any of them for the current quarter (IRS, Instructions for Form 720).
Read the first limb carefully, because it is the one that catches people. A business that filed once and then stopped having liability is still expected to keep filing until it files a final return. The obligation does not lapse on its own.
Responsible for collecting matters too. Several of these taxes are collected from a customer rather than borne by the filer, so a business can owe the return without the tax being its own economic cost. Where the burden actually falls, across excise and other indirect taxes, is set out in consumption tax.
The Four Deadlines
A return is due for each quarter of the calendar year, and the due dates are fixed rather than tied to the entity’s own year end (IRS, Instructions for Form 720).
| Quarter covered | Due by |
|---|---|
| January, February, March | April 30 |
| April, May, June | July 31 |
| July, August, September | October 31 |
| October, November, December | January 31 |

Where any due date falls on a Saturday, Sunday or legal holiday, the return may be filed on the next business day (IRS, Instructions for Form 720).
One tax runs on its own calendar inside that pattern. The floor stocks tax on ozone-depleting chemicals is reported on the return due by July 31 each year, but the tax payment itself is due by June 30 (IRS, Instructions for Form 720), so the payment date precedes the filing date rather than following it.
A Quarter With No Tax Still Needs Care
Two situations look like nothing to do and are not.
Where the filer is not reporting a tax it normally reports, it enters a zero on the appropriate line in Part I or Part II. Where it has no tax to report at all, it enters None on Part III, line 3, and signs the return (IRS, Instructions for Form 720). A blank line and a zero are not the same statement, and the instructions ask for the zero.
The Final Return Is How Filing Stops
A final return is filed where the business goes out of business, or will not owe excise taxes reportable on Form 720 in future quarters (IRS, Instructions for Form 720). A filer whose only remaining purpose is to report zero, and who will not owe excise tax in future quarters, checks the Final return box above Part I (IRS, Instructions for Form 720).
That single box is what closes the loop opened by the first filing test. Without it, the obligation to keep filing continues.
The Contents Change Every Year
This is the part that makes the return unlike an income tax return: the list of taxes and their rates is rewritten frequently, so last year’s understanding of the form is not a safe guide to this year’s.
The June 2026 instructions record several changes for 2026. A new section 4475 imposes a 1% excise tax on certain remittance transfers occurring after 2025, reported under its own IRS number (IRS, Instructions for Form 720, Rev. June 2026). The patient-centered outcomes research fee moved: for policy and plan years ending on or after October 1, 2025 and before October 1, 2026 the applicable rate is $3.84 multiplied by the average number of lives covered, while for policy and plan years ending on or after October 1, 2024 and before October 1, 2025 it remains $3.47 (IRS, Instructions for Form 720, Rev. June 2026).
Taxes also expire. The oil spill liability taxes on crude oil received and on petroleum products entered expired after 2025, and the instructions caution against entering the expired taxes on their lines unless Congress extends them (IRS, Instructions for Form 720, Rev. June 2026).
The practical consequence is that both the rate and the existence of a line have to be checked against the current instructions each quarter, not carried forward from the last one.
Where a Firm Meets It
Rarely, and usually late. Excise liability tends to sit outside the payroll and income tax calendar a firm runs on, so it surfaces when a client’s business model quietly puts it inside a taxable category: a plan sponsor picking up the research fee, a business arranging air transportation, a fuel user, or now a business handling remittance transfers.
Three habits keep it from becoming a penalty conversation. Establish whether any IRS number on the form applies before the first quarter closes rather than after it, because the deadlines do not move with the client’s year end. Keep filing until a final return is filed, since stopping quietly does not end the obligation. And check the current instructions for rate and expiry changes each quarter, because this form changes in ways an income tax return does not.
Recordkeeping is the underpinning: copies of the return, records and accounts of all transactions are kept to show that the correct tax has been paid (IRS, Instructions for Form 720).
Common Questions
Only if you are liable for, or responsible for collecting, one of the taxes listed in Parts I and II of the form, either for the current quarter or for a prior quarter where no final return has been filed (IRS, Instructions for Form 720). Most businesses never touch it. The ones that do usually fall into a category because of what they sell, transport, manufacture, import or sponsor rather than because of their size.
The person the statute makes liable, who is not always the person who bears the cost. Some of these taxes are collected from a customer by a business that then remits them, which is why the filing test is written as liable for, or responsible for collecting (IRS, Instructions for Form 720).
Accountably places trained offshore accountants and tax preparers inside US CPA and EA firms, and a firm can put a block of its own compliance and return preparation through a trial task so its reviewers stay on the judgment calls.
