What Is and Is Not Taxed in Idaho
Groceries are not exempt in Idaho: unprepared food is taxed at the full 6% state rate — groceries are taxed at the full state rate, offset by a per-person grocery tax credit.
Prescription medicines are exempt in Idaho, as they are in every state that levies a sales tax; over-the-counter drugs and most medical supplies are treated separately and are frequently taxable.
Out-of-state sellers must register and collect Idaho tax once they cross the state's economic nexus threshold, a rule that follows from the 2018 Supreme Court decision in South Dakota v. Wayfair. Below that threshold, the buyer technically owes use tax instead.
