Idaho

The IFTA diesel fuel tax rate in Idaho is 32.0¢ per gallon, which is 8.0¢ lower than your home state (New York: 40.0¢/gal). Includes excise tax. This rate is reported on your quarterly IFTA return and net taxes owed or credited are calculated based on miles driven vs. fuel purchased in each jurisdiction.

Idaho participates in IRP; registration through Idaho Transportation Department. No separate state operating permit; UCR registration required. Your IRP registration covers operating in Idaho as long as it is listed on your cab card. If Idaho is not on your cab card, you will need a temporary trip permit: $41.50 for 72-hour temporary trip permit; available at ports of entry.

Single-trip permit: $32; annual permit: $100; pilot car requirements for wide loads. Permits required for loads over 8.5 ft wide, 14 ft high, 75 ft long, 105,500 lbs; seasonal weight restrictions on some routes. Always obtain permits before entering the state with oversize or overweight loads, as fines for operating without proper permits can be substantial.

Federal hazmat requirements apply; Idaho follows FHWA routing guidelines. All drivers transporting hazardous materials must have a valid CDL with hazmat endorsement (HME), which requires a TSA background check. Check Idaho's specific routing requirements before hauling hazmat loads through the state.

Ports of entry on I-84, I-90, I-15, US-95; mandatory entry for all CMVs. Bypass programs available: PrePass, Drivewyze; Idaho port of entry bypass for qualified carriers. Carriers with good safety records and proper credentials may qualify for bypass at equipped stations, saving time and fuel.
