Hawaii sales tax at a glance

What sales tax adds at the register
At the average combined rate of 4.5%:
| Price | Sales tax | Total |
|---|---|---|
| $25 | $1.13 | $26.13 |
| $100 | $4.50 | $104.50 |

Hawaii vs. the national average
The average combined state-and-local sales tax across the 50 states is about 6.66%. Hawaii's 4.5% is 2.16 points below that — on a $30,000 car, about $648 less than the national average buyer pays. Combined with a graduated income tax topping out at 11%, that shapes how Hawaii funds itself — see the Hawaii paycheck calculator for the payroll side.
Reading a Hawaii receipt
A Hawaii receipt typically shows tax as a single line at the combined rate, even though the money is split between the state and one or more local jurisdictions. To check a receipt: multiply the taxable subtotal by 0.0450 (the 4.5% average) — if the tax line is meaningfully higher, you're in a locality above the average, up to 4.5%; if lower, some items were exempt (groceries and prescriptions are exempt or reduced in most states). The reverse mode on the calculator above recovers the pre-tax price from any total.
