How sales tax works in Idaho

Sales tax is charged on most retail purchases. The rate you actually pay is the 6.00% state rate plus whatever your city and county add — the combined figure of 6.03% above is a state-wide average, so two addresses in Idaho can pay different amounts. Groceries, prescription drugs and some other categories are often taxed at a lower rate or exempt.

For online orders shipped to Idaho, the seller generally collects the buyer's local rate (destination sourcing) if they exceed the state's economic-nexus threshold. See how US sales tax works and sales tax vs use tax.
