An excise tax is a federal tax on a specific good or activity, collected from the manufacturer, importer, or seller rather than charged to the buyer at checkout. The cost gets built into the sticker price and passed through to consumers, which is why most people never see it broken out on a receipt. The United States has used excise taxes since 1791, and today they apply to products and services ranging from gasoline and cigarettes to airline tickets and indoor tanning.
How an Excise Tax Differs From a Sales Tax or Income Tax
Three features set excise taxes apart. First, they target specific items rather than consumption in general. A state sales tax applies to almost everything you buy at a retail counter; an excise tax applies only to the products Congress has singled out.
Second, they are usually charged as a flat dollar amount per unit rather than a percentage of price. The federal government taxes gasoline at 18.4 cents per gallon whether the pump reads $2.50 or $4.00.1Office of the Law Revision Counsel. 26 USC 4081 – Imposition of Tax A sales tax, being percentage-based, moves with the price.
Third, excise taxes are indirect. The IRS collects them from a business, and the business decides how much of the cost to pass along. Income taxes work the opposite way: the government collects directly from the person who earned the money.
What Federal Excise Taxes Apply To
Modern federal excise taxes cover a wider slice of the economy than most people realize. The main categories are fuel, tobacco, alcohol, heavy vehicles, certain chemicals, firearms and ammunition, aviation, and a handful of specific services.
Fuel
Gasoline is taxed at 18.3 cents per gallon and diesel at 24.3 cents per gallon, plus a 0.1-cent surcharge on each for the Leaking Underground Storage Tank Trust Fund. The effective totals are 18.4 cents for gasoline and 24.4 cents for diesel.1Office of the Law Revision Counsel. 26 USC 4081 – Imposition of Tax These rates were last set in 1993 and have not been adjusted for inflation since.
Tobacco and Alcohol
Small cigarettes are taxed at $50.33 per thousand, roughly $1.01 per pack of twenty.2Office of the Law Revision Counsel. 26 USC 5701 – Rate of Tax Distilled spirits carry a general rate of $13.50 per proof gallon, with reduced rates for smaller producers: $2.70 per proof gallon on the first 100,000 proof gallons and $13.34 on the next 22.13 million.3Office of the Law Revision Counsel. 26 USC 5001 – Imposition, Rate, and Attachment of Tax
Heavy Trucks and Vehicles
New heavy trucks, tractors, and trailers face a 12 percent retail excise tax at sale. Separately, heavy vehicles with a registered gross weight of 55,000 pounds or more owe an annual use tax. The rate starts at $100 for the 55,000-to-75,000-pound range (plus $22 per additional 1,000 pounds over 55,000) and caps at $550 for vehicles above 75,000 pounds.4Federal Highway Administration.

Environmental Chemicals
The Superfund excise tax was enacted in 1980, lapsed in 1995, and was reinstated in 2022. It applies to 42 listed chemicals at varying per-ton rates to fund hazardous waste cleanup, along with a related tax on crude oil received at refineries and imported petroleum products.5Internal Revenue Service.

Aviation and Other Services
Aviation excise taxes apply to domestic passenger tickets, flight segments, international departures and arrivals, cargo waybills, and aviation fuel.7Federal Aviation Administration. Airport and Airway Trust Fund The Affordable Care Act added a 10 percent tax on indoor tanning services, collected by the provider and remitted to the IRS.8Internal Revenue Service.

Where Excise Tax Revenue Goes
Unlike income taxes, which flow into the general treasury, most excise tax revenue is earmarked for specific trust funds. This user-pays structure ties the tax to the people who benefit from the spending.
The Highway Trust Fund is the largest example. Fuel taxes, the heavy vehicle use tax, the retail tax on heavy trucks, and the tax on tires all flow into it under 26 USC 9503 to pay for road construction, bridge repair, and mass transit.9Office of the Law Revision Counsel. 26 USC 9503 – Highway Trust Fund The Airport and Airway Trust Fund collects aviation-related excise taxes to finance the national air traffic system and airport improvements, with the Treasury Department projecting $21.3 billion in trust fund excise tax revenue for fiscal year 2026.7Federal Aviation Administration. Airport and Airway Trust Fund The Sport Fish Restoration and Boating Trust Fund follows the same logic, drawing from excise taxes on recreational fishing equipment and boat fuel to support fishery conservation and boating access.
Excise taxes now account for roughly 2 percent of total federal revenue. During the Depression, they generated nearly half.10Joint Committee on Taxation. Background Material on Excise Taxes Income and payroll taxes now do the heavy lifting, and excise taxes have settled into a more targeted role: funding specific programs and discouraging specific behaviors.
The Constitutional and Statutory Basis
Article I, Section 8 of the Constitution gives Congress the power to “lay and collect Taxes, Duties, Imposts and Excises” to pay debts and provide for the common defense and general welfare.11Congress.gov. ArtI.S8.C1.1.1 Overview of Taxing Clause One constitutional requirement matters for excise taxes specifically: they must be uniform throughout the United States. The rate on a gallon of gasoline or a pack of cigarettes is the same in Maine as it is in Montana.
The specific statutory authority for modern federal excise taxes lives in Title 26 of the Internal Revenue Code, primarily in Subtitle D (miscellaneous excise taxes) and Subtitle E (alcohol, tobacco, and related excise taxes).12Office of the Law Revision Counsel. 26 USC Subtitle E – Alcohol, Tobacco, and Certain Other Excise Taxes
A Brief History of Federal Excise Taxes
The first federal excise tax arrived in 1791, when Congress passed a tax on domestically produced distilled spirits at rates ranging from six to eighteen cents per gallon depending on proof. Alexander Hamilton had argued in his 1790 Report on Public Credit that a central government strong enough to manage its debts needed the power to tax domestic production.13Federal Reserve Bank of St. Louis. Annual Report of the Secretary of the Treasury, 1790 The tax fell hardest on small-scale frontier farmers who used whiskey as both a drink and a medium of exchange, and resistance in western Pennsylvania became the Whiskey Rebellion. Washington called out the militia; the rebellion collapsed without a pitched battle.14TTB: Alcohol and Tobacco Tax and Trade Bureau. The Whiskey Rebellion
The Civil War transformed federal taxation. The Internal Revenue Act of 1862 expanded excise taxes to cover a wide range of consumer goods, including telegrams, jewelry, liquor, and tobacco, and created the Bureau of Internal Revenue to collect them.15National Archives. Internal Revenue Service That bureau eventually became the modern IRS. The Spanish-American War brought a federal tax on telephone service in 1898 that was billed as temporary but persisted for over a century in some form. World Wars I and II added “emergency” taxes on luxury goods, many of which quietly became permanent.
The 16th Amendment, ratified in 1913, gave Congress the power to tax incomes directly, and income taxes gradually became the dominant revenue source.16National Archives. 16th Amendment to the U.S. Constitution – Federal Income Tax Excise taxes surged back during the Great Depression, when the Revenue Act of 1932 imposed new levies on gasoline (one cent per gallon), tires, and electricity to generate immediate cash for federal relief.17Internal Revenue Service. The Federal Excise Tax on Gasoline By fiscal year 1933, excise taxes made up 45 percent of all federal tax revenue.10Joint Committee on Taxation. Background Material on Excise Taxes
How Businesses Report and Pay
Businesses that manufacture, import, or sell taxable products report and pay federal excise taxes on IRS Form 720, filed quarterly with deadlines of April 30, July 31, October 31, and January 31.18Internal Revenue Service. Instructions for Form 720 (Rev. March 2026) Certain activities also require advance registration on Form 637, which covers businesses involved in fuel production, chemical manufacturing, and other regulated operations.19Internal Revenue Service. About Form 637, Application for Registration (For Certain Excise Tax Activities) The IRS requires records to be kept for at least four years from the date the tax was due, paid, or claimed.
Why the Gas Tax Keeps Coming Up
The federal gasoline tax illustrates the structural pressure on excise revenue. Set at 18.4 cents per gallon in 1993, it has not been adjusted in over three decades. Inflation has eaten away more than half its real value, and improving vehicle fuel efficiency means fewer gallons sold per mile driven. The Highway Trust Fund has repeatedly needed general-fund transfers to stay solvent.
Policy proposals to close the gap include indexing the gas tax to inflation, converting it to a percentage of retail price, or replacing it with a per-mile fee charged on distance rather than fuel consumed. None has passed. The math gets harder as electric vehicles grow their market share and pay no fuel taxes at all.
