How to Use a Credit and Amend a Mileage Tax Report

Temporary pass and trip permit fees are generally non-refundable, but carriers can request a tax credit by completing the following form.
More information about Amending Tax Reports is in our Motor Carrier Registration and Tax Manual.

Fuels Tax Credits

More information about Fuel Tax Credits is in our Motor Carrier Registration and Tax Manual.

Motor carriers can buy fuel in Oregon at commercial fueling stations without paying a fuel tax if they enroll in the Oregon Weight-Mile Tax Program. Without proper enrollment, the fuel provider must charge fuel taxes.

When a carrier who is paying weight-mile taxes also pays a fuel tax, they can request a refund of the fuel tax on their next weight-mile tax report with the Commerce and Compliance Division. A claim for credit can be processed when it is supported by proper documentation from the actual seller of the fuel. See OAR 740-055-0110 for information required on fuel purchase records and refunds.
