How self-employment tax works
As a self-employed tutor, you pay a 15.3% self-employment tax (12.4% Social Security + 2.9% Medicare) on 92.35% of your net profit, plus federal and state income tax. A common rule of thumb is to set aside 25–30% of your net income for taxes.
Quarterly estimated tax deadlines (2025)
If you expect to owe $1,000 or more, the IRS requires quarterly estimated payments. For 2025 income the deadlines are: April 15, 2025; June 16, 2025; September 15, 2025; and January 15, 2026. Missing them can trigger underpayment penalties. The calculator above estimates your quarterly amount.
