Consumers usually pay Idaho fuels tax when they buy fuel from a retail dealer in Idaho. The price paid usually includes the cost of the fuels tax.
Exceptions
- Dyed diesel
This diesel fuel is meant for off-road use only. It’s dyed red to distinguish it from diesel for road use. - Gaseous fuels
Tax is included only if it’s put directly into the supply tank of a licensed motor vehicle. - Racing fuels
High-octane, leaded gasoline used in motor vehicles designed for racing isn’t taxed as a motor fuel. - Buying from an Idaho Indian tribe or member
The fuel sold by these retailers won’t include Idaho fuels tax, but will include a tribal fuel tax.
