Self-Employment Taxes in Indiana
Self-employed individuals in Indiana pay the same federal self-employment tax as workers in every other state: 12.4% for Social Security (on the first $176,100 of net earnings in 2025) and 2.9% for Medicare, totaling 15.3%. This is calculated on 92.35% of your net self-employment income. An additional 0.9% Medicare tax applies to earnings above $200,000 ($250,000 married filing jointly).
In addition to federal taxes, Indiana applies a flat 3.0% state income tax on your self-employment earnings after deductions. Self-employment income is treated as ordinary income for state tax purposes.
Remember to make quarterly estimated tax payments (due January 15, April 15, June 15, and September 15) to avoid underpayment penalties. The calculator above breaks down your quarterly payment amounts.
