Indiana taxes self-employment income through its state income tax. This calculator adds the Indiana brackets on top of federal self-employment and income tax so you see one number to hold back from every payment.

For a single filer in Indiana with $72,000 of 1099 income and $9,000 of expenses and no other income, the calculator estimates a set-aside rate of 19.4%: $8,902 of self-employment tax, $3,827 of federal income tax, and $1,252 of Indiana income tax.
Federal estimated payments are due April 15, June 15 and September 15, 2026, and January 15, 2027, if you expect to owe $1,000 or more after withholding. Indiana has its own estimated tax schedule and safe-harbor rules; the state share in the tracker is a quarter of the projected annual state tax.
Track it all year with the 2026 Set-Aside Tracker, which includes every state.
