How Indiana Income Tax Works in 2026

Indiana runs a flat-rate income tax: every dollar of state taxable income is taxed at the same percentage (3.05% for 2026). Flat systems make withholding and estimated-tax planning predictable, but they offer less progressivity than the federal seven-bracket schedule.

Your starting point is usually federal AGI, adjusted for Indiana-specific additions (e.g., federal QBI add-back) and subtractions (retirement income exclusions, municipal-bond interest). Apply the 3.05% flat rate, then subtractIndiana-specific credits (EITC match, child/dependent care, residential energy) to arrive at state tax owed.

Retirement Income, Social Security & Pensions

Indiana: Retirement income fully taxable.

Whether you live in Indiana during retirement matters as much as where you saved. Pre-tax 401(k) and IRA contributions reduce both federal and (in most states) state taxable income today, while Roth contributions and conversions are taxed up front. If you plan to retire in a no-income-tax or retirement-friendly state, frontloading Roth conversions before you move can permanently lock in lower rates.
