What this rate applies to
Idaho publishes the taxable base separately from the rate. Groceries, prescription drugs, clothing and services are treated differently state to state, and several categories in Idaho are taxed at reduced rates or exempt entirely. Idaho permits local option sales taxes only in designated resort cities; Boise is not one, so the state rate stands alone. Check the Idaho State Tax Commission guidance for the category you are pricing before assuming 6% applies.
