Frequently Asked Questions


What is the tax rate on motor fuel?

There are different levels of taxes that are charged on motor fuel. These include Federal, State, and Local taxes along with some other fees. At the Federal level, there are different rates depending on type of fuel in question. The current rates for the most commonly used motor fuels are as follows:

Fuel Type Rate (¢ per gallon)  
Gasoline 18.4  
Diesel and Kerosene 24.4  
Liquefied Petroleum Gas 18.3 These tax rates are based
on energy content relative
to gasoline
Liquefied Natural Gas 24.3
Compressed Natural Gas 18.4

Included in the Gasoline, Diesel/Kerosene, and Compressed Natural Gas rates is a 0.1 ¢ per gallon charge for the Leaking Underground Storage Tank Trust Fund.

Most states have similar types of taxing scales although some do have additional charges such as sales taxes, petroleum business taxes, environmental fees, and clean-up fees.

How is the fuel tax collected?

At the Federal level, the majority of the taxes are collected when product is removed from the bulk storage terminals. The companies pay the tax to the Internal Revenue Service (IRS). The states have different rules for the point of taxation as some tax the product “at the rack”, which is upon removal from the bulk terminal, while other states impose the tax at the distributor level, having a series of approved bulk distributors, who hold licenses and file regular (usually monthly) returns where the state and local taxes are paid.

Where does the revenue from the fuel tax go?

The revenue from the collected Federal fuel taxes are deposited into the Highway Trust Fund, which has several accounts. Though the percentages vary depending on the fuel type, the majority (approximately 83 to 87%) is deposited into the Highway Account, to be used on road construction and maintenance. An additional amount (approximately 11 to 15%) goes to the Mass Transit Account, and for many fuels, 0.1 cents per gallon goes to the Leaking Underground Storage Tank Trust Fund. Some States have similar trust funds, but there are a number of ways the revenue is handled.

Is anyone exempt from the fuel tax?

The IRS defines taxable events for motor fuel, which are specific to the types of fuel. For the majority of motor fuel used in the United States (gasoline and diesel) the only exemptions would be for licensed exporters who are delivering product out of the US, and for dyed diesel and dyed kerosene out of terminals approved by the IRS for such activity.

What is a LUST fee?

The LUST fee is the Leaking Underground Storage Tank (LUST) Trust Fund. Congress created the Leaking Underground Storage Tank Trust Fund in 1986 by amending Subtitle I of the Resource Conservation and Recovery Act. The LUST Trust Fund has two purposes. First, it provides money for overseeing and enforcing corrective action taken by a responsible party, who is the owner or operator of the leaking UST. Second, the Trust Fund provides money for cleanups at UST sites where the owner or operator is unknown, unwilling, or unable to respond, or which require emergency action.

What is the difference between dyed diesel and clear diesel fuel?

Fuels that are designed for non-highway use (such as farm or construction equipment) have generally been allowed to contain a higher level of sulfur than fuel for on-highway vehicles.  The Environmental Protection Agency (EPA) in conjunction with the Internal Revenue Service (IRS) created rules in which the higher sulfur fuels, designed for off road use, would be dyed so that it could be identified for the high sulfur content, and also could be sold without fuel tax, since it was not to be used on highway.  The IRS and many state revenue and law enforcement agencies have comprehensive testing programs to check for the illegal use of the dyed fuel in highway vehicles.
