Indiana self-employment tax, in plain terms
Self-employment tax, 15.3% of your net earnings for Social Security and Medicare, is federal and the same in every state. What differs in Indiana is the income-tax layer. Indiana taxes your self-employment profit at its own rates on top of federal income tax, so your all-in effective rate runs a few points higher than in a no-income-tax state. The calculator above already applies Indiana's brackets, so the number you see is the real one.

Do I pay quarterly estimated taxes in Indiana?
