How sales tax works in Idaho

Idaho (ID) applies a statewide base sales-tax rate of 6%. Most cities and counties add a local sales tax on top, so the combined rate you actually pay is usually higher than the state base — enter your local rate in the calculator above for an exact figure. Categories such as groceries, prescription drugs, and clothing are treated differently from state to state; this estimate assumes a fully taxable purchase.

What to know about Idaho sales tax

  • Idaho replaced its graduated income tax with a single flat rate applied above a low income floor.
  • Groceries are taxed, but Idaho provides a per-person grocery tax credit to offset it.
  • Most local jurisdictions cannot levy a general sales tax, so the combined rate is close to the state base in most areas.
