Fuel tax facts

On June 30, 2016, all current fuel tax licenses will expire. You must reapply for a new fuel tax license to continue operations in Washington. We encourage you to register your account early through the Taxpayer Access Point (TAP). TAP also provides you an easier and faster way to manage your fuel tax accounts.

TAP is now available for Fuel Tax and Unlicensed Refund customers. Please be patient with staff, as we might experience some delays with the implementation of a new system.
