Im a nonresident buying a car in Idaho. Do I need to pay sales tax on my car?
A nonresident who buys a vehicle from a dealer owes sales tax on the vehicle if it stays in Idaho more than 60 days in a 12-month period. This applies to nonresident members of the military as well. However, nonresidents who will take the vehicle to another state or country and immediately license and title it there can buy the vehicle without paying sales tax if they properly complete a Form ST-104MV.
