An excise tax is a federal, state, or local tax on a specific product, service, or activity, collected from the business that produces or sells it and folded into the price before you ever see a receipt. The federal excise tax on a gallon of gasoline, for example, is 18.3 cents, and most people never notice it because it is baked into the pump price rather than added at the register. Excise taxes touch everyday purchases like fuel, airline tickets, alcohol, and tobacco.
How an Excise Tax Differs From Sales Tax
The easiest way to understand an excise tax is to set it next to the sales tax you already know. A general sales tax applies to a broad range of goods and services at a percentage of the purchase price, and it shows up as a separate line on your receipt. An excise tax is narrower on every dimension. It applies to a short list of targeted products. It is usually charged per unit — per gallon, per pack, per ticket — rather than as a percentage of price. And it almost never appears as a separate line item on a consumer receipt.
Because excise taxes are invisible at checkout, most people underestimate how much they pay. A driver filling a 15-gallon tank pays about $2.76 in federal fuel excise taxes alone, before any state fuel tax is added. A smoker buying a pack of cigarettes pays $1.01 in federal excise tax before state and local taxes pile on. The tax is already inside the sticker price, so you pay it whether or not you realize it.
How the Amount Is Calculated
Federal excise taxes fall into two categories based on how the amount is determined.
A specific tax charges a flat dollar amount per physical unit, regardless of the product’s price. Most federal excise taxes work this way. Gasoline is taxed at 18.3 cents per gallon whether gas costs $2.50 or $4.50. Cigarettes are taxed at a flat rate per thousand sticks. The tax stays the same no matter what the item sells for, which means it hits cheaper brands proportionally harder than expensive ones.
An ad valorem tax charges a percentage of the sale price. The federal tax on heavy trucks and trailers, for instance, is 12 percent of the retail sale price. If a truck chassis sells for $80,000, the excise tax is $9,600. When prices rise, the tax rises automatically.
Common Federal Excise Taxes You Pay
Federal excise taxes reach a wider range of products and activities than most people realize.
Motor Fuel
The federal government taxes gasoline at 18.3 cents per gallon and diesel fuel at 24.3 cents per gallon, plus a 0.1-cent-per-gallon fee for the Leaking Underground Storage Tank trust fund. Aviation rates vary: commercial aviation kerosene is taxed at 4.3 cents per gallon, while fuel for private and general aviation runs 19.3 cents (aviation gasoline) or 21.8 cents (kerosene for noncommercial use) per gallon.1Office of the Law Revision Counsel. 26 USC 4081 Imposition of Tax These rates have not changed since 1993, so they do not adjust for inflation. Revenue flows primarily into the Highway Trust Fund.
Alcohol
Distilled spirits carry a general federal excise tax of $13.50 per proof gallon. Small distillers get a meaningful break: the first 100,000 proof gallons removed in a calendar year are taxed at $2.70 per proof gallon, and the next batch up to 22,230,000 proof gallons at $13.34.2TTB: Alcohol and Tobacco Tax and Trade Bureau. Tax Rates Wine and beer have their own rate schedules under the same subtitle of the tax code, with rates that vary by alcohol content and production volume.3Office of the Law Revision Counsel. 26 USC Ch. 51 Distilled Spirits, Wines, and Beer The tax is collected from the producer or importer before the bottle reaches a store shelf.
Tobacco
Federal excise tax on small cigarettes is $50.33 per thousand, which works out to about $1.01 per pack of 20.4Office of the Law Revision Counsel. 26 USC 5701 Rate of Tax Large cigarettes, cigars, pipe tobacco, chewing tobacco, and roll-your-own tobacco each have separate rate structures. These rates were last set in 2009, when Congress more than doubled them as part of the Children’s Health Insurance Program Reauthorization Act.
Air Travel
Every domestic airline ticket carries a 7.5 percent excise tax on the fare price.5Office of the Law Revision Counsel. 26 USC 4261 Imposition of Tax On top of that, each domestic flight segment adds a flat fee of $5.30 per passenger for 2026, indexed annually to the Consumer Price Index.6Federal Aviation Administration. Trust Fund Excise Taxes Structure – Rates Effective January 1, 2026 A round-trip flight with one connection in each direction has four segments, so those flat fees alone add $21.20 to the ticket. Revenue goes to the Airport and Airway Trust Fund.
Wagering
The federal government taxes wagers at 0.25 percent of the amount wagered for bets placed legally under state law, and 2 percent for unauthorized wagers.7Office of the Law Revision Counsel. 26 USC 4401 Imposition of Tax The tax is paid by the entity accepting the wager, not the bettor.
Indoor Tanning
A 10 percent excise tax applies to any indoor tanning service, added to the amount paid by the customer.8eCFR. 26 CFR Part 49 Subpart G – Indoor Tanning Services This one is unusual because it works as a percentage of price rather than the flat per-unit charge used for most excise taxes. The provider collects it and remits it to the IRS.
Heavy Vehicles
Highway vehicles with a taxable gross weight of 55,000 pounds or more owe an annual Heavy Highway Vehicle Use Tax, reported on IRS Form 2290. The tax period runs from July 1 through June 30 of the following year, and the return is due by the last day of the month after the vehicle is first used on public highways.9IRS.gov. Instructions for Form 2290 (Rev. July 2026) Separately, the first retail sale of a heavy truck chassis, trailer, or tractor-type vehicle triggers a 12 percent excise tax on the sale price.10Internal Revenue Service. Instructions for Form 720
Firearms and Ammunition
Under the Pittman-Robertson Federal Aid in Wildlife Restoration Act, manufacturers and importers pay an excise tax of 11 percent on long guns and ammunition and 10 percent on handguns. The revenue funds wildlife conservation and hunter education programs administered by state agencies.
State and Local Excise Taxes Come on Top
The federal figures are only part of the picture. Every state imposes its own excise taxes on fuel, tobacco, and alcohol, often at rates that dwarf the federal levy. State gasoline taxes range from roughly 9 cents per gallon to over 70 cents per gallon depending on the state, and state cigarette taxes run from under 20 cents per pack to more than $5.00 per pack. A single purchase can trigger both the federal excise tax and one or more state and local excise taxes at the same time.
Local governments add another layer. Many cities and counties impose excise taxes on hotel stays, rental cars, entertainment admissions, or cannabis sales. The result is a layered system where the total excise tax burden on a product depends heavily on where you buy it.
Who Legally Owes It and Who Actually Pays
Legally, the business producing, importing, or selling the product owes the excise tax. Practically, you pay it. The manufacturer or distributor writes the check to the IRS, but that cost gets built into the wholesale price, which gets built into the retail price, which comes out of your wallet. This is what economists mean when they call excise taxes indirect. The legal incidence (who files the return) and the economic incidence (who actually bears the cost) land on different parties.
The invisible nature of these taxes matters for how big they can get. Because you never see a separate line item, an excise tax generates less political friction than a visible sales tax of the same size. Consumers also tend to blame high prices on producers rather than on the tax component that may account for a significant share of the cost. Cigarettes are the starkest example: combined federal, state, and local excise taxes can easily exceed the manufacturer’s price for the actual product.
When Excise Tax Doesn’t Apply
Not every use of a taxed product triggers a tax obligation. Fuel used for certain purposes qualifies for a credit or refund through IRS Form 4136. Qualifying uses include farming, off-highway business use (like construction equipment that never touches a public road), commercial fishing vessels, school buses, and exclusive use by state or local governments and nonprofit educational organizations.11Internal Revenue Service. Instructions for Form 4136 and Schedule A (2025) Personal use, commuting, and recreational vehicles like snowmobiles and lawn mowers do not qualify.
Products manufactured for export can also be exempt from federal excise tax, provided the exporter maintains documentation proving the goods left the country. State and local governments can purchase certain fuels tax-free for their exclusive use, or claim refunds for fuel purchased with the tax already included.
If Your Business Collects Excise Tax
Businesses that owe federal excise taxes report and pay them quarterly using IRS Form 720:
- January through March: due April 30
- April through June: due July 31
- July through September: due October 31
- October through December: due January 31
If a deadline falls on a weekend or legal holiday, the due date shifts to the next business day.10Internal Revenue Service. Instructions for Form 720 Businesses with quarterly excise tax liability above $2,500 must also make semimonthly deposits during the quarter. A late-filed return carries a penalty of 5 percent of the unpaid tax per month, capped at 25 percent, and a late payment adds 0.5 percent per month, also capped at 25 percent.12Office of the Law Revision Counsel. 26 USC 6651 Failure to File Tax Return or to Pay Tax Those penalties run at the same time, so a business that files late and pays late faces both.
