Idaho Sales Tax Calculator
Idaho sales tax applies to most retail sales of tangible goods and some services. This calculator shows the combined state and local sales tax rate for any location in Idaho and lets you work out the tax on a given purchase price or reverse-calculate the pre-tax amount from a total. Select your county or city to load the exact local rate on top of the Idaho statewide base rate, then enter any purchase amount to see the tax and total immediately. Rates and jurisdictions are sourced from Idaho State Tax Commission and reflect current Idaho law. Sales tax in Idaho applies at the point of sale for most tangible personal property; groceries, prescription drugs, and other categories may be exempt or taxed at a reduced rate depending on state law. Use the calculator to compare totals across different jurisdictions, or to verify a receipt. The combined rate shown is the rate applicable at a specific location and accounts for any special district taxes layered on top of the county or municipal rate.

sales tax = pre-tax price x (state rate + local rate) / 100
total = pre-tax price + sales tax
Worked example
A $250.00 purchase in Sun Valley, at the 8% combined rate (6% state + 2% local):
- Combined rate = 6% + 2% = 8%.
- Sales tax = 250 x 0.0800 = $20.00.
- Total = 250 + 20.00 = $270.00.

Does Idaho have local sales taxes?

The only local sales taxes are the voter-approved resort city taxes in about 23 designated cities (such as Sun Valley, Ketchum, McCall and Stanley) and the lodging taxes charged by a few auditorium districts. These local taxes are set by local ordinance, vary by what they apply to, and are added on top of the 6% state rate.

Yes. Idaho taxes groceries at the regular 6% state sales tax rate. To offset that, Idaho residents can claim the grocery (food) credit on their state income tax return, generally $155 per person (or up to $250 if you keep receipts for the sales tax you paid on food).
What is the sales tax rate in Sun Valley or Ketchum?
Sun Valley and Ketchum are resort cities, so they add a local resort sales tax on top of Idaho's 6% state rate. Because each resort city sets its own rate and taxable goods by ordinance, the Idaho State Tax Commission does not publish a single combined figure and directs shoppers to the city or its official resort-city list for the current rate.
