As a self-employed fitness instructor, your tax bill is based on your net income — what's left after business expenses. That makes deductions one of the most powerful tools you have: every legitimate dollar you write off is a dollar you don't pay self-employment or income tax on. Yet most instructors track only a fraction of what they're entitled to.
Here are the deductions multi-studio instructors most often qualify for — and most often miss.
Certifications and continuing education
The cost of keeping your credentials current is deductible: initial certifications, renewals, specialty trainings, workshops, and CECs. If a course makes you better at the job you already do, it generally counts.
Mileage between studios
This is the big one for instructors who teach at more than one location. Driving between studios in a day is deductible business mileage, and at the IRS standard rate (70¢ per mile in 2025, 72.5¢ in 2026) it adds up fast. A 25-mile round trip between two studios, three times a week, is over 3,900 miles a year — roughly a $2,800 deduction.
Note: your commute from home to your first studio of the day usually isn't deductible, but the hops between studios are. Keep a simple log of the dates and miles.
Music and app subscriptions
The services you use to do your job are deductible: music streaming for classes, choreography or programming apps, scheduling tools, and yes — software you use to run the business side, like tracking pay and taxes.
Equipment and gear
Mats, weights, bands, a mic, a portable speaker, heart-rate gear — equipment you buy to teach is deductible. So is professional attire that's required and branded for your work (everyday athletic wear you'd wear anyway is murkier).
Liability insurance
If you carry your own professional liability or general liability insurance, the premiums are deductible business expenses.
Home office (if you qualify)
If you have a space used regularly and exclusively for the business side of teaching — programming classes, admin, virtual sessions — you may qualify for a home office deduction. The rules are strict, so confirm before claiming it.
The catch: you have to track them
Deductions only help if you can document them. Receipts, mileage logs, and a record of what each expense was for are what turn "I think I spent about…" into a deduction that survives scrutiny.
This is exactly the kind of thing that's miserable to reconstruct in April and easy to capture as you go. ClassTally logs expenses and mileage alongside your pay, so your deductible total is ready when taxes are.
