How the tax works.

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.

Trade-ins: Value of a vehicle taken in trade by the seller is excluded from the sales price (Idaho Code 63-3613).
