Hawaii Tax Calculator

Hawaii runs the most finely tiered income tax bracket system of any state, spreading rates across many narrow bands so the tax burden increases gradually as income rises. Hawaii also levies a general excise tax on businesses that functions much like a sales tax, even though it's structured differently. This calculator applies Hawaii's full bracket schedule to your entered income.
