# About the Iowa Fuel Tax Credit

Ethanol Blended Gasoline is separated into two different categories: E-10 to E-14 and E-15 or higher (including E-85).
Taxpayers may claim a tax credit on their income tax returns for fuel that was purchased during the tax period to be used in unlicensed vehicles for nonhighway purposes.
If you filed a fuel tax refund claim during the tax year, you cannot also claim a Fuel Tax Credit; your refund permit will become invalid if you claim a Fuel Tax Credit. However, the Fuel Tax Credit is not available for casualty losses, transport diversions, idle time, pumping credits, off-loading procedures, reefer units, blending errors, power take-offs, ready mix, solid waste, export by distributors, or tax overpaid on blended fuel. A refund can be claimed for those reasons alongside the Fuel Tax Credit.
Dyed diesel fuel is always sold free of Iowa fuel tax.
No Fuel Tax Credit may be claimed for dyed diesel fuel.
All undyed special fuel used in watercrafts is eligible for the Fuel Tax Credit; however, gasoline used in a watercraft does not qualify for the tax credit unless the watercraft was used by a commercial fisher licensed and operating under an owner's certificate for commercial fishing gear issued pursuant to Iowa Code section 482.7.

# Pass-Through Entities - Allocation of Tax

Credit
The tax credit calculated on lines 1 through 7 by a pass-through entity (partnership, LLC, S corporation, estate, or trust) is allocated to the members. The tax credit allocation must be in the ratio of each member's share of the earnings of the entity to the entity's total earnings. Special allocations are not permitted. The pass-through entity must file the IA 4136 and the federal 4136 with its return.
Report the tax credit to the Department and to members as instructed (see Where to Report This Tax Credit).
2025 IA 4136 Instructions, page 1
If the taxpayer earns a tax credit and is a member of a pass-through entity that has passed through a tax credit to the taxpayer, calculate the tax credit on IA 4136, lines 1 through 7 and enter the passthrough tax credit on line 8. Report each tax credit separately.

Claiming This Tax Credit

Federal Employer ID Number or Social Security

# Number: Enter your Federal Employer ID Number

(FEIN) or Social Security Number (SSN). Do not enter your canceled fuel tax refund permit number.
Fuel Used For: Mark the proper box(es) to indicate how the fuel was used. Review your invoices to verify that Iowa fuel tax was paid before claiming a tax credit. This area must be completed.
Lines 1-6: Invoice Gallons - Based on the invoice date, enter the total number of whole gallons of fuel purchased on which Iowa fuel tax was paid during your tax year. Invoices must be issued in the name of the taxpayer or entity claiming the tax credit.
Retain invoices for three years after your return is filed.
Highway Gallons - Enter the number of whole gallons included in invoice gallons that were used on the highway.
Claimed Gallons - Subtract highway gallons from invoice gallons to calculate claimed gallons.
Fuel Tax Paid - Multiply the claimed gallons by the appropriate tax rate per gallon in each row.
Sales Tax - Iowa sales tax is owed on all fuel claimed for the tax credit except that used in exempt activities such as farming and processing. To compute sales tax, within each row, calculate the average cost per gallon of fuel purchased minus the relevant per gallon Iowa fuel tax. Multiply the result by the claimed gallons. Multiply this amount by the Iowa sales tax rate of 6% to calculate the sales tax owed.
Fuel Tax Credit - Subtract sales tax from the fuel tax paid. Any Fuel Tax Credit claimed must be net of sales tax owed.
