Idaho Reverse Sales Tax Calculator.

Idaho has a straightforward 6% state sales tax rate, and unlike many states, Idaho does not allow counties or cities to levy additional sales taxes. The only local add-on is a 3% travel and convention tax that applies specifically in resort cities like Sun Valley, Ketchum, and Stanley — not a general sales tax but a targeted tourism levy.

This simplicity makes Idaho one of the easier US states for sales tax compliance. There is essentially one sales tax rate for most retail sales anywhere in Idaho: 6%. Businesses operating in Idaho don't need to worry about different city rates, county add-ons, or special district taxes affecting their calculation (except in the specific resort communities).

Idaho exempts several important categories from sales tax: prescription drugs, most groceries (food for human consumption, excluding prepared food and restaurant meals), agricultural products used in production, manufacturing equipment and materials used in production, and most sales to government entities. The grocery exemption is broad — most items you'd find at a grocery store for home cooking are exempt.

Idaho's Department of Revenue administers the state sales tax. Returns are due monthly for larger sellers, quarterly for medium sellers, and annually for those with very small tax liabilities. Idaho offers a 2.5% prompt payment discount (up to $50/month) for timely filers.

Sales tax in Idaho is destination-based — meaning you apply the rate at the buyer's location. For most in-state sales, this is simply 6%. For Idaho's economic nexus, remote sellers with $100,000 or more in Idaho sales annually are required to collect and remit the state sales tax regardless of physical presence.
