Idaho charges sales and use tax of 6% statewide on vehicles, with no local add-on. A trade-in does reduce the taxable price, which is real money on the deal.
Idaho has no local sales tax on vehicle purchases; a few resort cities levy local option taxes, but those do not reach vehicles registered outside the city.
Manufacturer rebates do not reduce the taxable sales price in Idaho; dealer discounts do.
Registration fees are from the ITD fact sheet (July 2017 schedule still in force per the 2025 repost); title fee $14 per ITD title fee notice.
| Fee | Amount |
|---|---|
| Title | $14.00 |
| Registration (age-based) | ~$85 |
| Plates | $7.50 |
| EMS and state police fees (annual) | $4.25 |
Lease tax applies to each monthly payment rather than to the full price of the car, so you pay it as you go.
Pick your city for the exact combined rate where you register, plus what title and registration run there.
6%. Idaho applies one rate statewide on vehicles, so it does not change from city to city.
Value of a vehicle taken in trade by the seller is excluded from the sales price (Idaho Code 63-3613).
Title is $14.00. Passenger vehicles 8,000 lbs or less: $69 (1-2 years old), $57 (3-6 years), $45 (7+ years); plus plates $3.75 each, EMS $1.25, ISP $3, county administrative fee (varies) and county highway district fees where they exist (e.g., Ada County $24-$40). EV add $140, PHEV $75 per year.
No. Idaho sets no statutory cap, and dealers typically charge around $399. No statutory cap. Typical from CarEdge 2026 (secondary).
Tax applies to each monthly payment rather than the whole price of the car, so the tax is spread across the lease.
Rates, fees, and rules change. These figures are estimates for planning, not tax advice; confirm the final numbers with the dealer and your state's motor vehicle agency before you buy.
