What Is Quarterly Federal Excise Tax?

Quarterly federal excise tax is not one tax. It is a collection of federal taxes on particular things: a gallon of diesel, a domestic flight segment, a heavy truck sale, a tanning session, a covered life on a self-insured health plan. The IRS gathers them on one quarterly federal excise tax return, Form 720, sorted by an identifying code called an IRS No.

Most businesses never touch this return. The ones that do usually make, import, or sell a taxed item, or take payment for a taxed service. If that might describe you, the Form 720 eligibility checker is a quick first test. The rest of this page explains how the tax works.

What is federal excise tax?

A federal excise tax is a tax the federal government places on a particular good, service, or activity, rather than on income or on sales in general. It applies only to what the law lists, and each tax has its own rate, its own tax base, and its own taxable event, such as fuel being removed at a terminal rack or a heavy truck’s first retail sale. For how this differs from a state sales tax, see sales tax vs excise tax.

Form 720 carries most of them, but not all. IRS Publication 510 points to other returns for the rest:

• Heavy highway vehicle use tax on trucks, truck tractors, and buses with a taxable gross weight of 55,000 pounds or more is reported on Form 2290.
• Wagering taxes are covered by Form 730 and Form 11-C.
• Alcohol, tobacco, and firearms tax forms come from the Alcohol and Tobacco Tax and Trade Bureau (TTB.gov), not the IRS.

How is excise tax calculated?

Each line on Form 720 works the same way: the tax base times the rate for that IRS No. What changes from tax to tax is the base. It might be gallons, the price of a sale, the amount paid for a service, or the number of people covered by a health plan. The examples below use rates printed on the June 2026 Form 720 and its instructions.

The tax base has its own rules for each tax, which is where most of the work is. The truck tax, for example, has rules on what is included in the price and what is left out. See truck excise tax for those, and the PCORI fee guide for the ways to count covered lives.

Who does quarterly federal excise tax touch?

The instructions set one test. You must file if you are liable for, or responsible for collecting, any federal excise tax listed in Form 720, Parts I and II. That wording creates two different kinds of filer.

• The business that owes the tax itself. A tire manufacturer owes the tax on taxable tires it sells. A seller owes 12% on the first retail sale of a taxable truck or tractor. An employer that sponsors a self-insured health plan owes the annual patient-centered outcomes research fee, usually called the PCORI fee.
• The business that collects it from someone else. An airline collects air transportation tax from passengers. A tanning salon collects 10% from customers. A phone service provider collects 3% on local telephone service. The customer pays, but the collector sends in the money and files.

The IRS gives a clear collector example. A passenger pays $268.60 for a two-segment flight in January 2026. That is a $240 fare plus $28.60 of tax: 7.5% of the fare ($18.00) plus two domestic segments at $5.30 ($10.60). The passenger is liable, and the airline collects the tax and submits it. For a list organized by type of business, see who must file Form 720.

Once you are in the system, you stay in it. The test also covers anyone who was liable in a prior quarter and hasn’t filed a final return. Publication 510 puts it directly: file Form 720 for each calendar quarter until you file a final Form 720.

The four due dates, with the next ones on the calendar

Each return covers a calendar quarter. When a date lands on a Saturday, Sunday, or legal holiday, you may file on the next business day, and that happens often in this stretch of the calendar.

Not every filer uses all four. If the PCORI fee is your only excise tax, you file only the second-quarter return, once a year. The stock repurchase tax (IRS No. 150) is also reported once a year.

How do Part I and Part II differ?

The split is about how the money reaches the IRS. Publication 510 describes Part I as taxes generally required to be deposited during the quarter, and Part II as taxes that aren’t.

Part III then pulls the two totals together. It subtracts Schedule C claims, deposits, and overpayments carried from earlier quarters, and shows either a balance due or an overpayment.

Why “quarterly” can be misleading

The word describes the return, not always the payment. Two details catch new filers.

Money can be due long before the return. Generally, a business with Part I liability above $2,500 for the quarter must deposit twice a month. Paying everything with the return instead may bring a penalty. Fuel excise taxes are a common example of Part I taxes. Publication 510 also warns that a business that doesn’t make deposits as required may have to file monthly or semimonthly rather than quarterly.

A quiet quarter still needs a return. If you aren’t reporting a tax you normally report, enter a zero on that line. If you have nothing at all to report, enter “None” on Part III, line 3, then sign and date. If you are finished with excise taxes, check the Final return box so the return is treated as your last.

How to file a quarterly federal excise tax return

There are two routes. You can mail the paper form to the IRS in Ogden, Utah. Or you can file electronically through a provider in the IRS e-file program for excise taxes. The IRS describes electronic filing of Form 720 as optional, with immediate acknowledgment of receipt among its benefits.

Whichever you choose, you need the same things: your EIN, the quarter ending date, your figures for each IRS No., any semimonthly liabilities and deposits, and any claims.

To file Form 720 online with EasyFile720, an IRS-authorized e-file provider, you create a free account with no credit card and enter your business details. The guided steps then take you through your Part I and Part II categories, plus Schedules A, C, and T. Rates for the return are built in, and the math is calculated after you enter your figures. Validations catch common mistakes before you submit, you sign electronically, and you get an electronic acknowledgment from the IRS once the return is accepted. You pay when you file: $39.95 per filing. The July to September 2026 return is due November 2, so that is the next date to work toward if you had a Part I or Part II liability in that quarter.
