Washington Fuel Permit is a temporary authorization required for commercial carriers that do not have a valid IFTA (International Fuel Tax Agreement) license to operate in the state of Washington.
Historically, the need for such permits arose with the introduction of fuel taxes and interstate agreements in the United States during the second half of the 20th century. Before IFTA, each jurisdiction required separate reporting and payments, which created complicated administrative processes for long-haul truckers. Temporary Fuel Permits allowed companies to legally purchase fuel and pay the necessary taxes while traveling through Washington without long-term obligations.
Today, a Washington Fuel Permit is typically used:
-
when entering the state with vehicles not covered by an IFTA license,
-
for one-time trips where obtaining a permanent license is unnecessary,
-
for temporary operations or rented vehicles.
The permit is valid for 72 hours and covers the fuel tax required to legally conduct transportation activities within Washington State.
