How the Hawaii sales tax calculation works

Hawaii's sales tax rate is 4%: $4 on a $100 sale and $40 on $1,000. This is the state rate only. If a city, county or district in Hawaii charges its own tax, it is added on top of this rate. Enter your price and any local rate to see the Hawaii sales tax and the total.

  1. Start with the 4% state rate

    Hawaii charges 4% on taxable sales.

  2. Add your local rate if there is one

    If a city, county or district in Hawaii charges its own tax, it is added on top of this rate. Enter that rate as the local tax; Hawaii's revenue department lists the rate for each address.

  3. Multiply the price by the rate

    Divide 4% by 100 and multiply: $100 × 0.04 = $4.00, and $250 × 0.04 = $10.00.

  4. Add the tax to the price

    A $250 item in Hawaii costs the buyer $260.00 at the state rate, before any local tax.

Worked example. A $250.00 sale in Hawaii at the 4% state rate carries $10.00 in sales tax, for a $260.00 total. If a 1% local tax applied on top, the combined rate would be 5% and the Hawaii buyer would pay $262.50.
