Indiana Tax Calculator
Indiana applies a flat state rate to adjusted gross income, but that's only part of the picture: every Indiana county also levies its own local income tax on top of the state rate, so your total bill depends on where you live. Indiana's flat state rate is among the lowest of any state that taxes income at all. This calculator applies the state-level flat rate to your entered income.

How Indiana income tax works
- Indiana multiplies your adjusted gross income by a flat state rate — there are no state brackets.
- Every Indiana county layers its own additional local income tax on top of the state rate.
- Your total Indiana tax bill therefore depends on both the state rate and your county of residence.

No. Indiana excludes Social Security benefits from state taxable income.
Does Indiana have local income taxes?
