What makes up a sales tax rate in Idaho
- The state's share: 6%. Levied on every taxable sale in Idaho, wherever it happens.
- Local shares: nothing to ~3% on top. Counties, cities and special districts each add their own, and a seller collects them together. 22 cities in Idaho have their own pages with a figure below.
- Your exact address decides. A ZIP code is a postal route and was never drawn to follow tax boundaries, so two addresses sharing one can owe different totals. The calculator narrows it down from your ZIP code.

Why most Idaho figures are estimates
Of 325 ZIP codes in Idaho, 1 resolves to a single verified rate for every address inside it. The rest carry an estimate with its range, and the calculator will ask for more than a ZIP code where it needs to.
- 295 A local district in this state is not yet mapped, so this may not be the whole rate.
- 21 This ZIP code crosses a tax boundary, so the rate depends on the street address.
- 8 No tax data is loaded for this area yet.
A ZIP code is a mail route, not a tax boundary. Where one crosses a city or district line, the rate depends on the street address, and no lookup by ZIP code alone can settle it. Enter your ZIP code in the calculator for the closest figure we hold.
