Hawaii sales tax rate
Hawaii charges a statewide sales tax of 4%. Cities, counties and special districts can add their own local sales taxes on top, which brings the population-weighted average combined rate to about 4.5% in 2026. Because local rates differ from place to place, the exact rate at a given address may be higher or lower than the average.
How to calculate Hawaii sales tax
Multiply the price by the rate: sales tax = price × rate ÷ 100, then add it to the price for the total. For a $100 purchase at the combined 4.5% rate, the tax is $4.50 and the total is $104.50. Use the calculator above for any amount, and swap in your local rate if you know it.

What's taxed in Hawaii
Groceries are taxed at the full 4% state rate — Hawaii is one of the few states that gives food no break at the register. Clothing is taxed like any other goods. Whether services are taxable depends on the state and the type of service. If you invoice for services, confirm the rule with the Hawaii Department of Taxation before adding sales tax.
Selling into Hawaii and which rate to charge
Since the 2018 Supreme Court decision in South Dakota v. Wayfair, a business with no physical presence in Hawaii must register and collect its sales tax once sales into the state exceed $100,000 or 200 separate transactions. The measurement period (current or previous year, or a rolling 12 months) is set by the state, so check it before you cross the line. Hawaii is not a Streamlined Sales Tax member, so out-of-state sellers register directly with the Hawaii Department of Taxation.
Hawaii uses destination-based sourcing: charge the rate at the buyer's delivery address. That's why the same order can carry different rates in different parts of the state — and why the average above is only a reference.
Good to know about Hawaii
Hawaii doesn't have a classic sales tax. Its General Excise Tax (GET) is imposed on the business and covers almost every activity, services included, so freelancers and consultants usually add it to their invoices as a visible pass-on.
