Idaho RV Registration Fee Calculator

RV registration in Idaho splits by type. Self-propelled motorhomes register like other motor vehicles — motorhomes pay the age-based passenger fee ($45–$69) PLUS the RV value fee on the living-quarters portion (25–60% of value depending on chassis type). Towed travel trailers and campers run on a separate schedule: roughly $130 per year. Formula: $4 base + an RV value fee of $8.50 for the first $1,000 of depreciated market value plus $5 per additional $1,000 — a $25,000 fifth-wheel runs about $130/yr, declining as the state depreciation table kicks in. Because motorhome MSRPs are large, value-based charges hit RVs harder than any other vehicle class.

Frequently asked questions

How much does it cost to register a motorhome in Idaho?

Motorhomes follow Idaho's regular vehicle fee system (motorhomes pay the age-based passenger fee ($45–$69) PLUS the RV value fee on the living-quarters portion (25–60% of value depending on chassis type)) — use the calculator above with your RV's MSRP and weight. In value-based states a $150,000 Class A can cost several thousand dollars a year at first.

Yes — travel trailers are towed, unpowered vehicles and run on their own schedule (about $130 per year), separate from both motorhomes and small utility trailers.
