Applying Tax to Runways Instead of Roads
The Division of Aeronautics uses the aircraft engine fuel tax to support Idaho airports and aviation programs. This tax is included in the price of aviation gasoline and jet fuel.
Some airplane owners have their planes certified to use motor vehicle gasoline ("mo-gas"). This tax goes to support Idaho roads. These airplane owners can choose to support Idaho runways instead.
Different tax rates could mean a refund
Motor vehicle gasoline and undyed diesel are taxed at higher rates than aviation fuel. If you used taxed gasoline or undyed diesel in an aircraft you can file to claim a refund for the amount you overpaid.
Claim a refund and pay the aircraft fuels tax
You must meet both these requirements:
- You bought at least 50 gallons of motor vehicle gasoline.
