Hawaii income tax cut calculator

Enter your tax information below to see how Hawaii’s historic income tax cut will affect you.

This calculator works for only taxpayers claiming the standard deduction. Taxpayers who itemize their deductions might see smaller savings. 

Originally created by the Hawaii Department of Taxation, the calculator estimates how much taxpayers will save as a result of HB2404, which was approved unanimously by the Legislature, signed into law by Gov. Josh Green. It applies to income earned starting Jan. 1, 2024. 

The new law increased the standard deduction for people filing jointly, single or as a head of household, and will gradually expand the sizes of each of the tax brackets, meaning that all taxpayers will see more of their income taxed at lower rates. 

To read more about how the bill works, read the Department of Taxation’s blog here.
