As of 2026

Idaho charges a 6% state sales tax. Only a small number of resort cities add a local option tax, so the statewide average local add-on is near zero (about 0.03%).

This is the state base plus the average local rate, not an address-exact rate. Your actual rate depends on your city, county, and special district, and can be higher or lower than the state average.
Groceries and prescription drugs are exempt or taxed at a lower rate in most states. A blended rate over-taxes those categories. Use it for general merchandise.
Clothing rules vary sharply. Pennsylvania and New Jersey exempt most clothing; Massachusetts exempts clothing up to $175 per item; New York exempts items under $110. Check your state before assuming apparel is taxed.
