Idaho Sales Tax Calculator
Figure the tax, the total, or the pre-tax price for any U.S. state or city rate
Idaho charges a 6% state sales tax on most retail purchases — one of the more straightforward rates in the Mountain West. Unlike many states, Idaho's local sales tax additions are minimal: a handful of designated resort cities (such as Sun Valley and Ketchum) are authorized to add up to 3% in local resort taxes, but these only apply in those specific jurisdictions. Statewide, the average combined rate sits at just 6.03%, according to the Tax Foundation, meaning that for the vast majority of Idaho shoppers the rate they see is essentially the state rate.
One notable Idaho quirk: groceries are fully taxable at the standard 6% rate. Idaho is one of only about six states that taxes most food items at the full rate (hot prepared foods and restaurant meals are also taxed). To offset the burden on lower-income households, Idaho offers an income-tax-based grocery credit — $155 per person starting in fiscal year 2026 — but that does not reduce the tax at the register.
How to use this calculator: Enter the purchase price in the Amount field and the applicable sales tax rate in the Rate field. For most Idaho locations, leave the rate at 6.03% (average combined). If you are shopping in a resort city like Sun Valley, you may need to check the local rate, which can reach up to 9%. The calculator instantly shows both the tax amount and the total price. Use it for budgeting before a big purchase, reconciling a receipt, or estimating costs when shopping online from an Idaho address.
Practical example — Idaho
On a $500 appliance purchase at a Boise retailer, you would pay $30.00 in state sales tax (6%), for a total of $530. In a resort city like Sun Valley with a local resort tax, the same appliance could cost up to $545.

Yes. Idaho exempts prescription drugs, certain medical devices, farm equipment used in agriculture, and some manufacturing equipment from sales tax. Sales to qualified non-profit organizations and government entities may also be exempt. Online sales to Idaho customers are taxable if the seller has nexus in the state.
How does Idaho's sales tax compare to neighboring states?
Idaho's 6% rate is moderate compared to neighbors. Utah also has a 6.1% combined rate; Montana has no sales tax at all; Nevada's combined rate averages around 8.23%; and Wyoming's averages about 5.44%. Oregon has no sales tax. This makes Idaho a middle-of-the-pack state for sales tax in the region.
