Indiana State Income Tax Guide (2026)
Indiana charges a flat 3.05% state income tax on all taxable income, one of the lowest flat rates in the Midwest.
1. Indiana Flat Tax Rate
Indiana applies a single flat income tax rate of 3.05% to taxable income. Unlike progressive states, the same rate applies whether you are an entry-level worker or a high earner, which makes the calculation straightforward.
2. Deductions and Conformance
Indiana does not offer a standard deduction, so the rate applies from the first dollar of taxable income. Pre-tax 401(k) contributions, HSA contributions, and employer health premiums reduce your Indiana taxable income.
3. Local Taxes to Watch
Indiana counties levy an additional local income tax (typically 0.5% to 2.0%) on top of the state rate, not included here.
