Indiana Tax Calculator

The Indiana (IN) Tax Calculator is updated for the 2026/27 tax year and estimates Indiana state income tax, federal income tax, and FICA/Medicare contributions. Indiana applies a flat state income tax rate plus county income taxes that vary by location. This calculator helps Hoosiers estimate total taxes and take-home pay for both state and federal levels.

Indiana offers various credits, including the Earned Income Credit, College Credit, and Unified Tax Credit for the Elderly. Use this calculator to explore how these affect your annual return.
