Hawaii Tax Calculator

The Hawaii (HI) Tax Calculator is updated for the 2026/27 tax year. It estimates your Hawaii state income tax, federal tax, and FICA/Medicare withholdings to show accurate net take-home pay. Hawaii uses a progressive income tax system with twelve brackets ranging from 1.4% to 11%, one of the most detailed in the U.S.

Residents, nonresidents, and part-year residents can use this calculator to compare taxable income, assess credits like the Food/Excise Credit and Renewable Energy Technologies Credit, and plan for estimated payments or refunds.
