General Instructions
Purpose of Form

Use Form 4136 to claim the following.
• The biodiesel or renewable diesel mixture credit.
• The alternative fuel credit.
• A credit for certain nontaxable uses (or sales) of fuel
during your income tax year.
• A credit for blending a diesel-water fuel emulsion.
• A credit for exporting dyed fuels or gasoline
blendstocks.
Attach Form 4136 to your tax return.
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

any credits you claim before claiming a credit on Form
4136 or a refund on Form 8849.

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
