Self-Employment Taxes in Ohio
Self-employed individuals in Ohio 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).
Ohio taxes self-employment income as ordinary income through its progressive bracket system. Higher earnings push you into higher state tax brackets, just like the federal system. Your effective state rate depends on your total taxable income after deductions.
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.
