10 Surprising Facts About Fuel Excise Tax You Didn’t Know
- Fuel excise tax is a fixed levy, not a percentage of price, meaning the government collects a fixed amount per gallon regardless of fuel price movements.
- Fuel excise taxes fund more than highways; in many countries, they also support public transit and environmental programs.
- Business users may receive credits that reduce the effective excise cost, while households pay the full fuel excise tax included in pump prices.
- Fuel excise tax can significantly influence behaviour, including fuel conservation and even vehicle purchasing choices.
- Fuel excise duty varies internationally, with some countries indexing it for inflation and others not.
Understanding the Facts About Fuel Excise Tax
A fuel excise tax is usually a specific rate (¢/gal) on a fuel sold (as opposed to a percentage (%) of the sale price), unlike sales tax.
A fuel excise tax has many functions. First, it is a major source of tax revenue; Second, it helps to pay for infrastructure such as roads; Third, it can influence how much fuel people buy; and Fourth, in some jurisdictions, it may also be used to achieve environmental policy objectives.

Surprising Facts About Fuel Excise Tax
1. The Fuel Excise Tax Is Usually Based on Quantity and Not Price
- A fuel excise tax is usually a fixed cents per gallon of gasoline (e.g., 18.4¢/gal federal). When the price of fuel goes up significantly, the amount of the excise tax does not necessarily increase proportionately.
2. Consumers Pay Full Excise, But Some Businesses Don’t
- Consumers who purchase gasoline (including businesses) will pay the full amount of the fuel excise included in the price at the pump. However, some business fuel users will receive an excise rebate or credit for part or all of their fuel excise costs.
3. Fuel Excise Revenue Is Sometimes Used to Fund Transportation Projects
- In the US, the Federal Government uses most of the revenue generated by the federal fuel excise tax to fund the Highway Trust Fund, which is used to pay for the construction, repair, and maintenance of roads, bridges, and public transit systems. For more details on meeting these requirements, see our Form 720 Preparation Guide.
4. Fuel Excise Tax May Be Hypothecated
- Some government agencies will define or designate (hypothecate) how fuel excise tax revenue will be spent, such as for road repairs or for funding public transit; otherwise, it would simply go into general revenue.
5. Tax Structures Differ Between Countries
- Different countries adjust or index their fuel excise tax differently. For example, some index it to inflation (14 US states do) and others apply static nominal rates. Stay on top of deadlines with our guide to the Form 720 Due Date.
6. It Can Be Used to Influence Consumption and Environment
- Higher fuel prices from excise tax discourage overuse, promote conservation, and reduce pollution. Specific environmental levies like the LUST tax also play a role here.
7. Fuel Prices Often Include Multiple Layers of Tax
- Fuel prices include stacked taxes (federal excise + state excise + sales tax), which amplify the total tax burden on consumers.
8. Excise Duty Fluctuates with Policy
- Taxation is a very flexible tool for government revenue, and as needed, governments can adjust or cut rates during crises, though full elimination requires legislation.
9. The Burden on Consumers Is Influenced by Downstream Taxes
- When sales tax is applied after excise tax is already added, consumers end up paying tax on that tax, a scenario common in some jurisdictions.
10. Fuel Excise Makes Up a Large Share of Tax in Some Markets
- In the US, federal and state excise taxes often make up 20-40% of pump prices and a major revenue source for transport.
