Indiana Tax Calculator
Indiana has a flat 3.15% income tax — down from 3.4% — with scheduled reductions to 2.9% by 2027.
Indiana's flat 3.15% income tax rate is among the lowest in the country, with further statutory reductions planned to bring the rate down to 2.9% by 2027. The state levies a 7% sales tax on most goods — among the highest state-level sales taxes in the Midwest — but unlike most states, it allows no local sales tax additions, so the rate is uniform statewide. Indiana does not allow a standard deduction — taxpayers must itemize at the federal level. Property taxes are below the national mean at ~0.84%. The state's tax structure has been used aggressively to attract business, and Indiana offers one of the most favorable business climates in the country. Indiana also exempts Social Security income, military retirement pay, and civil service pensions from state tax. With Indianapolis serving as a logistics hub and population growth along the suburban counties, Indiana's revenue base has expanded despite the lowering rate.
