Frequently Asked Questions

How do Hawaii's tax brackets work?

Hawaii uses 12 progressive brackets similar to the federal system. Each rate applies only to income within that bracket range, so your effective rate is always lower than your top marginal rate of 11.00%.

Is Hawaii's income tax in addition to federal tax?

Yes. You pay both federal income tax and Hawaii state income tax. This calculator shows your combined total tax burden from both.

What is Hawaii's top income tax rate?

Hawaii's top marginal income tax rate is 11.00%, which applies only to income in the highest bracket. Most earners pay a lower effective rate because earlier income is taxed at lower rates.
