Indiana Income Tax Calculator (2026 Filing Season)
Indiana has a flat 3% state income tax for the 2025 tax year.
State rate is a low 3.0%, but every Indiana county adds its own income tax (roughly 0.5%–3%), not included here.
Enter taxable income — this state has no standard deduction.
The same $75,000 income in a no-income-tax state (Texas, Florida, Tennessee…) would owe $0 in state income tax — a difference of $2,250 per year.
We only store your state and filing status — never your income.
