General Instructions

Purpose of Form

Use Form 4136 to claim a credit for certain nontaxable uses (or sales) of fuel during your income tax year. Also use Form 4136 if you are claiming the alternative fuel credit, a blender claiming a credit for a diesel-water fuel emulsion, or a producer claiming a credit for an alcohol fuel mixture, a biodiesel or renewable diesel mixture, or an alternative fuel mixture.

Instead of waiting to claim an annual credit on Form 4136, you may be able to file:

  • Form 8849, Claim for Refund of Excise Taxes, to claim a periodic refund; or

  • Form 720, Quarterly Federal Excise Tax Return, to claim a credit against your taxable fuel liability.

You cannot claim any amounts on Form 4136 that you claimed on Form 8849 or Schedule C (Form 720).

Partnerships.    Partnerships (other than electing large partnerships) cannot file this form. Instead, they must include a statement on Schedule K-1 (Form 1065), Partner's Share of Income, Deductions, Credits, etc., showing the allocation to each partner specifying the number of gallons of each fuel used during the tax year, the applicable credit per gallon, the nontaxable use or sale, and any additional information required to be submitted.

Additional Information

Recordkeeping

You must keep records to support any credits claimed on this return for at least 3 years from the date the return is due or filed, whichever is later.

Including the Fuel Tax Credit in Income

You must include in your gross income the amount of the credit from line 17 if you took a deduction on your tax return that included the amount of the taxes and that deduction reduced your income tax liability. See Pub. 510 for more information.
