Indiana self-employment tax, explained

Indiana's 2.95% state rate is only part of the picture — every Indiana resident also owes a county income tax on top of it (commonly around 1-2%, depending on county), so budgeting for just the state rate will understate the total.

Self-employment (SE) tax is the same everywhere — 15.3% of 92.35% of your net profit, split between Social Security (12.4%, up to the annual wage base) and Medicare (2.9%, uncapped). What changes by state is the income tax layer on top: Indiana has a flat 2.95% income tax rate, applied to your taxable income after federal deductions. For filing status, Indiana's tax applies at the same flat rate to every filing status, since it's a single rate rather than brackets.

Frequently asked questions

What is the Indiana state income tax rate for 1099 income?

Indiana has a flat 2.95% income tax rate. Its tax applies at the same flat rate to every filing status, since it's a single rate rather than brackets. See the "Indiana self-employment tax, explained" section above for how it applies to your specific numbers.

How is self-employment tax calculated?

Self-employment tax is 15.3% of your net self-employment earnings (92.35% of net profit): 12.4% Social Security up to the annual wage base, plus 2.9% Medicare on all net earnings. If your combined income exceeds the Additional Medicare Tax threshold for your filing status, an extra 0.9% applies above that threshold.

What's the difference between self-employment tax and income tax?

Self-employment tax funds Social Security and Medicare — it's the self-employed equivalent of the payroll taxes an employer would otherwise split with you. Federal (and state) income tax is separate, calculated on your taxable income after deductions like the standard deduction and the QBI deduction.
