Indiana Income Tax: 2.95% Flat Rate

Indiana uses a flat state income tax rate of 2.95% for 2026, down from 3.00% in 2025 (IC 6-3-2-1). Indiana has no standard deduction; each taxpayer and dependent gets a $1,000 personal exemption, and every dollar above it is taxed at the same 2.95% rate. All 92 counties also levy a local income tax (0.50%–3.38%) on the same base. This page shows state income tax only — use the Indiana paycheck calculator to add your county rate.

On top of the 2.95% state tax, Indiana residents also pay federal income tax ranging from 10% to 37%. This calculator combines both federal and Indiana state tax to show your total liability, effective rate, and take-home pay.

How Indiana's Flat Tax Compares

A flat tax simplifies filing — you pay 2.95% on all taxable income without navigating multiple brackets. For a single filer earning $60,000, Indiana state tax is about $1,741 (2.95% of $59,000 after the $1,000 exemption); at $100,000 it is about $2,921. County local income tax comes on top of both figures.

States with flat taxes tend to have simpler returns and more predictable tax bills. The trade-off is that lower-income residents pay the same percentage as higher earners, unlike graduated systems where rates increase with income.

Reducing Your Indiana Tax Bill

While you cannot change the flat rate, you can reduce your taxable income. Contributions to traditional 401(k) and IRA accounts reduce both your federal and Indiana state taxable income. The 2026 401(k) limit is $24,500 ($32,500 with catch-up for age 50+). HSA contributions are also pre-tax for both federal and state purposes in most states.

Tips for Getting Accurate Results

For the most accurate results, use up-to-date numbers from official sources. Double-check your inputs before calculating — small errors in the starting values can lead to significantly different outputs. If you are comparing scenarios, keep all variables the same except the one you are testing. Save or screenshot your results for future reference. This calculator uses standard formulas and is designed to give you a reliable quick estimate, though professional advice may be needed for complex situations.
