About Indiana's rates
Indiana imposes a flat state income tax rate on all taxable income: 3.00% for 2025, falling to 2.95% for 2026 as the multi-year phase-down continues. Counties add local income tax rates ranging from 0.50% to 3.15%, collected on the same return — so your county of residence determines a significant portion of your actual tax bill.
State tax sits on top of federal — see the current federal tax brackets and standard deductions to estimate your full 2025 liability.

Planning note
Indiana's county income tax can nearly double your state-level tax rate depending on where you live. When evaluating an Indiana relocation, check the county rate — it's as important as the state rate.
