How to Collect Idaho Sales Tax

Idaho is a destination-based sales tax state. This means sellers are required to collect the state + local combined sales tax rate at the buyer’s ship to address. Say you are based in Caldwell, Idaho but make a sale to a buyer in Boise, Idaho. You’d charge sales tax at the buyer’s combined state + local sales tax rate.
