Fuel tax refunds

Starting January 1, 2023, vehicle registrations allow the removal of your address. New registrations have your address located on the bottom. There's a dotted line showing where to cut it. This is optional and intended to provide address privacy in case of theft.

Things to know

The Taxpayer Access Point (TAP) online system is now available. It's an easier and faster way to manage your fuel tax accounts. Register your account through TAP.

Who may request a refund?

You may be eligible for a refund of the Washington State fuel tax if:

  • You're an individual or company who bought at least 41 gallons of Washington tax–paid fuel in the past 13 months
  • and
  • You used it for off road activities like:
    • boating
    • construction
    • farming
    • logging
    • landscape/lawn maintenance
    • export
    • auxiliary equipment such as the dumping mechanism on a dump truck, or the boom on a boom truck

If no Washington State fuel tax was paid, no refund can be issued.

A fuel tax refund permit

  • Visit TAP-PRFT Taxpayer Access Point to complete the application online.
  • or
  • By mail:
    • Complete the Fuel Tax Refund Permit application and send to the address listed on the form.
    • Don't send fuel invoices with your refund application.
    • Once we process your application, we'll mail you a Fuel Tax Refund Claim form with instructions.

Filing refund claims online

Access your account through TAP and complete the claim form for the correct period. The average fuel tax rate is updated in January and July of each year. You must submit a separate claim for each period with a different rate.

To avoid entering each invoice separately in TAP, you may complete and import the appropriate template below. When claiming a refund for Power Take Off (PTO) use, complete the appropriate PTO tab on the template.

Filing a refund claim by mail

  • Complete the Refund claim form mailed to you within 13 months of purchase date. The average fuel tax rate is updated in January and July of each year. You must submit a separate claim for each period with a different rate.
  • Include supporting documents and copies of fuel invoices to verify purchases.

Once your refund is processed, we will mail you another refund claim form and the State Treasurer's office will mail your refund check.

How refund amounts are calculated

Unless exempted by law, we'll deduct use (sales) tax from your fuel tax refund amount and remit it to the Department of Revenue on your behalf. Refunds for marine use are also subject to Coastal Protection Fund fee.

You have 2 options to determine your refund:

  • Have us calculate the deduction for you. We'll use the average fuel cost per gallon and average sales tax rate.
  • Calculate the actual sales tax deduction. Submit a completed Actual Cost Computation Schedule with your claim. Contact us to receive this form.

Example of a refund claim amount calculated by the Department of Licensing:
Customer purchased 100 gallons of motor fuel at a total cost of $489.20 on January 1, 2023. They used this fuel off-road in their lawnmower and chainsaws.

  1. Calculate the state tax, 100 gallons x $ .494 (state tax rate) = $49.40
  2. Calculate the federal tax 100 gallons x. $ .184 = $18.40
  3. Deduct the federal and state tax from the cost of the fuel to avoid double taxation. $489.20 - $49.40 (state tax) and $18.40 (federal tax) = $421.40
  4. Apply the average sales tax, $421.40 x 8.7% = $36.66
  5. Deduct the average sales tax from the state fuel tax, $49.40 - $36.66 = $12.74. This is the total refund due to the customer.
