Fuel tax refunds

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.

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 $321 on July 1, 2019. 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. $321 - $49.40 (state tax) and $18.40 (federal tax) = $253.20
4. Apply the average sales tax, $253.20 x 8.5% = $21.52
5. Deduct the average sales tax from the state fuel tax, $49.40 - $21.52 = $27.88. This is the total refund due to the customer.
