Indiana Paycheck Calculator
Indiana has a flat state income tax rate of 3.05% in 2026, slightly reduced from prior years as part of the state's gradual rate reduction plan. Indiana also has county income taxes that apply on top of the state rate — every Indiana county levies a county-adjusted gross income tax (CAGIT or COIT) ranging from 0.5% to 3.38%. Marion County (Indianapolis) charges 2.02%. The combined state-plus-county rate for Indianapolis residents is approximately 5.07%.
Indiana's county income taxes are based on county of residence on January 1 of the tax year, not where you work. However, if you work in a county with a higher rate than your home county, you may owe the difference. Indiana employers are required to withhold both state and county income taxes.
Indiana follows federal adjusted gross income as the starting point for its state calculation. Traditional 401(k) contributions reduce Indiana taxable income, making them valuable for Indiana workers in terms of both federal and state savings.
