Idaho Weight-Distance Tax
No weight-distance or highway-use tax in Idaho. The state repealed its old weight-distance tax back in 2000, so there's no per-mile state tax to file today. You still owe IFTA fuel tax, IRP apportioned registration, and the federal 2290 HVUT at 55,000 lb and up — the same as every state. Don't read that as tax-free.

IFTA and registration still apply
Every state, including Idaho, still reaches you through the IFTA fuel tax (reconciled by the fuel you burn) and IRP apportioned registration (your plate). The only states that add a per-mile weight-distance or highway-use tax on top are Kentucky, New Mexico, New York, Oregon, and Connecticut.
