Fuel Excise Taxes on Form 720 for Transportation Businesses

Transportation companies involved in the manufacturing, sale, importation, distribution, or utilization of fuel subject to federal excise taxes should be able to file their fuel tax liability using Form 720, Quarterly Federal Excise Tax Return. Knowing which fuel taxes are subject to federal taxes will help transportation companies fill out Form 720 properly.

Form 720 will be the key form to use when filing taxes related to any fuels transaction, and this includes taxes required by Internal Revenue Code Sections 4041, 4042, 4081.

What Is Fuel Excise Tax?

The fuel excise tax is a federal tax imposed on certain fuels and the consumption of such fuels. Unlike the income tax, the excise tax is always applied to a particular item, transaction, or consumption of a certain commodity. Examples of commodities that are subjected to excise tax are kerosene, gas, and aviation fuel etc.

For transportation businesses, fuel excise taxes generally apply when taxable fuel is:
1)Removed from a refinery or terminal rack
2)Entered into the United States
3)Sold or used for taxable purposes
4)Used for specific transportation purposes

5)Subject to special regulations related to fuel under the Internal Revenue Code

Taxes collected through Form 720 contribute to government trust funds such as the Highway Trust Fund and other transportation programs.


Who Should Pay Fuel Excise Tax?

The party that must pay the fuel excise tax will depend on the nature of the transaction and the action done. The IRS usually holds manufacturers, producers, importers, sellers, position holders, or the users liable for paying the tax according to their categories.

Common scenarios where fuel excise tax may apply:

Business Activity 

Possible Fuel Tax Responsibility 

Refinery removes taxable fuel 

Tax may apply when fuel is removed from the refinery or terminal 

Fuel distributor holds inventory position at terminal 

Position holder may be liable for tax 

Importers bring taxable fuel into the U.S. 

Importer or enterer may be responsible 

Transportation business uses taxable fuel for taxable purposes 

Certain fuel use taxes may apply 

Business claims fuel credits but later fails qualification requirements 

Recapture taxes may apply 


Transportation Businesses That May Need to Consider Fuel Taxes

Examples include:
->Trucking companies using taxable fuel
->Fuel distributors and suppliers
->Marine transportation operators
->Aviation-related businesses
->Alternative fuel producers or users
->Businesses involved in fuel blending activities

The actual liability depends on the specific fuel activity and applicable IRS fuel tax category.

How Much Is the Fuel Excise Tax?

The fuel tax amount depends on the IRS tax category reported on Form 720. The IRS assigns each fuel tax a specific IRS No. and corresponding rate.

Below are some common fuel-related tax categories: 

IRS No. 

Fuel Tax Category 

Tax Rate 

62

Gasoline 

18.3 cents per gallon 

60

Diesel Fuel 

24.4 cents per gallon 

35

Kerosene 

24.3 cents per gallon 

120

Compressed Natural Gas (CNG) 

18.3 cents per gasoline gallon equivalent 

69

Aviation gasoline 

19.3 cents per gallon 

Note: Fuel tax rates may change based on legislative updates and IRS revisions. Always refer to the latest Form 720 instructions before filing.


Why Are IRS Nos. 64, 125, 51, and 117 Separate From the Main Fuel Tax Section?

Transportation businesses may notice that some fuel-related categories, such as IRS No. 64, IRS No. 125, IRS No. 51, and IRS No. 117, appear separately from the primary fuel tax categories on Form 720.

The IRS does not provide a specific explanation stating why these categories are separated. However, based on IRS instructions, these taxes are different from normal fuel taxes because they generally relate to special fuel uses, environmental taxes, or credit recapture situations rather than regular taxable fuel removal or sale transactions.

IRS No. 

Tax Category 

Reason It Is Different 

64

Inland Waterways Fuel Use Tax 

Applies based on the use of fuel in commercial inland waterways transportation under special fuel use rules. 

125

LUST Tax on Inland Waterways Fuel Use 

Related to the Leaking Underground Storage Tank Trust Fund and applies separately from normal fuel taxes. 

51

Section 40 Fuels

Applies when previously claimed fuel credits must be recaptured. 

117

Biodiesel Sold as But Not Used as Fuel 

Applies when biodiesel-related credit requirements are not satisfied. 

Therefore, these categories are separated because they do not follow the standard fuel tax calculation method of taxable gallons multiplied by a fuel tax rate.
Although these categories are listed separately from the main Fuel Taxes section, taxpayers who are liable for IRS Nos. 64, 125, 51, or 117 must report and pay the applicable tax using the correct IRS Number on Form 720.


Fuel Excise Tax Exemptions

The IRS provides exemptions and special rules for certain fuel uses. Businesses must meet specific requirements to qualify.
Common fuel tax exemptions include:
1)Fuel Dyed and Kerosene: The fuel being used for specific purposes that are exempt from tax may also be tax-exempt under IRC Section 4082, as long as the fuel meets all the required requirements of dyeing and marking.

2)Other nontaxable fuel uses: Certain special uses such as agricultural purposes, exportation, and certain government uses can also qualify for exemption from tax payments.

3)Alternative fuel and biodiesel: Eligibility requirements are separate for alternative fuel, biodiesel mixture, and renewable fuel credits.

The most recent information regarding the requirements should be reviewed by businesses to see if they meet the conditions of exemption or refund of tax.


Current IRS Updates Pertaining to Fuel Excise Tax

The corporations have to use the latest version of IRS forms and instructions before filing.

Changes Pertaining to SAF Credit

There has been an IRS update with regard to how sustainable aviation fuel credits will be treated, including their limitations and expiration period.

Updated Refund and Credit Procedures
Certain fuel-related refunds may require filing Form 8849 schedules instead of adjusting Form 720 liabilities. Businesses should review IRS guidance before submitting refund claims.
