Fuel Tax Credit: What Is It?

Regular gasoline and diesel fuel both reached above $5 per gallon in 2022—a record high that has put a strain on business and consumer budgets alike. This year’s fuel prices have impacted operations for business owners that operate vehicles or gas-fueled equipment.

That said, some business-related use of motor fuel is categorized as non-taxable. However, the only way to recoup that money is to claim a fuel tax credit when filing taxes for your enterprise. 

Below we’ll look at who qualifies for the credit and how to apply for it.

What Is the Fuel Tax Credit?

What is a fuel tax credit and why does it exist? The primary reason for the federal fuel tax credit is to give a break to non-highway-use fuel purchases.

The federal government imposes two types of tax on gasoline and diesel fuel:

  1. Excise tax Primarily used to maintain and repair highways and support mass transit
    (18.3 cents per gallon for gasoline; 24.3 cents for diesel)
  2. Cleanup tax To address leaking underground storage tanks.
    (0.1 cents per gallon on both types of fuel)

The federal tax on fuel is essentially a you-play-you-pay setup. The theory is that, regardless of income or assets, the more fuel you buy, the more strain you put on the public highway system—and thus the greater your responsibility for contributing to it.

Mostly this is true—we buy gas for cars, and we drive cars on roads. But what if you’re purchasing fuel for machines that never set foot (or tire) on public highways? 

Making gas stations responsible for sorting out who should or shouldn’t pay the federal tax isn’t practical. Instead, the excise tax is built into gas and diesel prices, and the government pays it back to qualifying businesses as a credit on their taxes. 

Who Can Qualify for a Fuel Tax Credit?

Whether you run delivery management operations or are in charge of fleet management costs, it’s best to know whether or not you qualify for a fuel tax credit. The federal fuel tax credit is a business credit—an individual or a partnership cannot claim it. Businesses can qualify for certain uses of: 

  • Regular gasoline
  • Diesel fuel (undyed)
  • Kerosene (undyed)
  • Aviation gasoline or kerosene
  • Specified alternative fuels

The most common example of nontaxable fuel use that qualifies for credit is for construction or farming equipment. However, per the IRS, the list also includes:

  1. Off-highway business use (for business use other than in a highway vehicle registered or required to be registered for highway use)
  2. Export
  3. In a boat engaged in commercial fishing
  4. In certain intercity and local buses
  5. In a qualified local bus
  6. In a bus transporting students and employees of schools (school buses)
  7. For diesel fuel and kerosene (other than kerosene used in aviation) used other than as a fuel in the propulsion engine of a train or diesel-powered highway vehicle (but not off-highway business use)
  8. In foreign trade
  9. Certain helicopter and fixed-wing aircraft uses
  10. Exclusive use by a qualified blood collector organization
  11. In a highway vehicle owned by the United States that isn’t used on a highway
  12. Exclusive use by a nonprofit educational organization
  13. Exclusive use by a state, political subdivision of a state, or the District of Columbia
  14. In an aircraft or vehicle owned by an aircraft museum
  15. In military aircraft

Note that the off-highway business use category can be applicable for many small businesses that use machinery such as:

  • Lawnmowers, snowblowers, and leaf blowers
  • Steam cleaners and vacuums 
  • Generators
  • Compressors and pumps
  • Power saws
  • Forklifts
  • Bulldozers and earthmovers

How to File for a Fuel Tax Credit

Before tax season, you’ll need to incorporate some recordkeeping. The first step in filing for a fuel tax credit is to keep track of fuel use throughout the year. 

A simple way to approach this is to assign fuel or fleet cards by purpose as well as use. If a specified card is used solely to purchase off-highway-use fuels, you’ll have a simple and clean tracking mechanism and legal record of your purchases. 

When tax time hits, you’ll file Form 4136, Credit for Federal Tax Paid on Fuels with the IRS. The four-page form is broken down by type of fuel. Under each, you’ll identify:

  • Usage category (farming, buses, trains, export, or nontaxable use)
  • Specific type of nontaxable use (per the 16-item list above)
  • How many gallons used

The form contains a per-gallon rate based on usage category—you’ll multiply the number of gallons by that rate for each type of use. Many businesses may just fill out the gasoline and/or diesel sections on page one and then skip to the end to enter a total amount.

Is There a Fuel Tax Credit in Your State?

When you hear a generic mention of tax credits or deductions, it’s usually about federal taxes. But you may be able to double down on getting your money back if your state also offers a fuel tax credit program. 

The majority of states impose a tax on fuel similar to the federal government approach—a “pay as you go” excise tax intended to be used for road construction and maintenance, as opposed to a sales tax intended to collect general use tax revenue concerning individual or business spending. 

Some states, such as California and New York, also follow the IRS’s lead in refunding taxes spent on fuel used in a nontaxable category (largely—if it’s not used on the highway, it shouldn’t be charged an excise tax to keep the highways in good repair). 

Is it worth checking if your state has a fuel tax credit? Most definitely—especially if you’re fueling up in the Golden State, Illinois, or Pennsylvania:

  • California – Tops the nation with 70.95¢ per gallon of gasoline and 102.01¢ diesel
  • Illinois –  59.6¢ per gallon of gasoline and 67.02¢ diesel
  • Pennsylvania – 58.7¢ per gallon of gasoline and 75.2¢ diesel

To compare, the average state gasoline tax is 29.15¢ per gallon, and the average state diesel tax is 31.19¢ per gallon.

Benefits of Fuel Tax Credits

Ideally, you’d never pay the excise taxes on fuel if you’re using it for a nontaxable purpose, but credit is the next best option. 

A tax credit provides you with a dollar-for-dollar fuel tax refund of your spending, as compared to a deduction, which only reduces your taxable income. For instance, if you paid $400 for fuel used in farming equipment, you’ll get $400 back with a tax credit versus $100 back in a deduction (based on a 25% tax rate). 

There is no cap (maximum) on the amount of fuel tax credit you can claim—it’s entirely dependent on how much qualifying fuel you’ve purchased. 

While it’s not unanimous, most analysts in a CNBC poll predict that oil prices will see a slight decline in the future. That said, fuel prices still aren’t cheap—and if you’re paying taxes you don’t need to, pursuing a fuel tax credit can provide your company with financial benefits.

Tax Credit for Alternative Fuels

Fuel tax credits have also been employed to incentivize businesses to experiment with alternative fuel mixture alternatives. These purchases may qualify for a tax credit regardless of use (including typical highway use by a standard consumer or commercial vehicle), plus additional credit if used in a nontaxable usage category. 

Currently, alternative fuels that qualify for a federal tax credit include:

  • Biodiesel and agri-biodiesel mixture types 
  • Compressed gas derived from biomass 
  • Compressed natural gas (CNG) 
  • Fischer-Tropsch process liquid fuel from coal (including peat)
  • Liquefied gas derived from biomass
  • Liquefied hydrogen 
  • Liquefied natural gas (LNG)
  • Liquefied petroleum gas (LPG) 
  • Liquid fuel derived from biomass 
  • Renewable diesel mixtures
  • “P Series” fuels

However, note that as technologies change, the types of alternative fuel and their tax credit rates also continue to change. Consult your tax and financial professionals about fuel credits as part of new equipment and motor vehicle investment planning.

This is another area to investigate at the state level—many states offer tax alternative fuel incentives to influence behavior related to alternative fuel and alternative-fuel machinery and vehicles.
