How the estimate works
As a fitness instructor paid on a 1099, you're self-employed in the eyes of the IRS. That means your tax bill has parts a W-2 employee never sees. This calculator estimates the three that matter most:
- Self-employment tax (15.3%) — Social Security and Medicare on 92.35% of your net self-employment income, the part an employer would normally split with you. Social Security stops at the annual wage base; Medicare has no cap.
- Federal income tax — applied to your taxable income (net income minus half your self-employment tax and the standard deduction) using the IRS brackets for your filing status.
- State income tax — estimated at a flat rate for common instructor states. States with no income tax (like Texas and Florida) show $0.
The quarterly figure divides your estimated annual tax into the four payments the IRS expects from self-employed people (Form 1040-ES). It uses the same math as ClassTally's in-app quarterly estimator.
What counts as a deductible expense?
Lowering your net income lowers all three taxes, so tracking deductions matters. Common write-offs for instructors include certifications and continuing education, liability insurance, music subscriptions, equipment, professional attire, and mileage between studios at the IRS standard rate.
Stop estimating, start tracking
This calculator works off one number you type in. ClassTally builds that number for you — logging pay across every studio, reconciling the deposits you actually received, and recording deductible expenses and mileage as you go — then estimates your quarterly taxes automatically.
