Hawaii Sales Tax Calculator

Hawaii applies a 4.00% state sales tax to most retail purchases. Counties, cities, and special districts can add up to 0.50% on top, so the actual rate you pay varies by jurisdiction. The statewide average combined rate is 4.50%.

Hawaii is one of the dwindling number of states that taxes groceries at the full sales tax rate. There's no reduced food rate — a gallon of milk and a flat-screen TV carry the same combined sales tax. Some states have phased out grocery taxes in recent years; track legislative changes if this affects your budget.

Hawaii pairs its sales tax with a top marginal state income tax of 11.00%, one of the higher rates in the country. The combined tax burden is a factor many remote workers and retirees weigh when comparing relocations.

For exact rates by ZIP code or address, use the Hawaii Department of Revenue's online lookup. The combined rate at the register is whatever the state rate plus the local jurisdiction add to — and local rates can shift each year as cities pass new measures. Run any purchase amount through the calculator above to see the breakdown.
