How Hawaii Sales Tax Works

Sales tax in Hawaii is collected at the point of sale on most tangible goods and some services. The state portion of 4% is uniform statewide, while local jurisdictions may add their own rates, averaging 0.5% across the state. Certain items like groceries and prescription medications may be exempt or taxed at reduced rates.

When budgeting in Hawaii, remember that sales tax affects your purchasing power. With a median home value of $722,500 and a property tax rate of 0.27%, understanding all taxes helps you make informed financial decisions.

What Is and Is Not Taxed in Hawaii

Groceries are not exempt in Hawaii: unprepared food is taxed at the full 4% state rate — the general excise tax applies to food, though federal food-assistance purchases are exempt.

Prescription medicines are exempt in Hawaii, as they are in every state that levies a sales tax; over-the-counter drugs and most medical supplies are treated separately and are frequently taxable.

Out-of-state sellers must register and collect Hawaii tax once they cross the state's economic nexus threshold, a rule that follows from the 2018 Supreme Court decision in South Dakota v. Wayfair. Below that threshold, the buyer technically owes use tax instead.
