For gym & fitness instructors

MTD for Income Tax for gym & fitness instructors.

Classes at several gyms paying per session, a mix of employed and self-employed work, and mileage between venues. Here's how Making Tax Digital for Income Tax applies to fitness instructors, and when it starts.

When does it start for me?

April 2027 for most, later if you're smaller.

MTD for Income Tax phases in by gross income before expenses. Instructors span a wide range, so it's worth pinning down which wave your self-employed income falls into.

Many venues, one record

Every gym is a separate income source.

Teaching per-class at several gyms means income from a few places, but it's all your self-employed income. Clear Books pulls it into one running record and one quarterly update, so multiple venues never means multiple headaches.

Multiple gyms

Every venue is one income source. Recorded together, they total into a single quarterly update.

Equipment, music licences, insurance and CPD are all deductible. Keep them recorded so your expenses stay complete.

Common questions

Fitness instructor MTD FAQ.

When does MTD for Income Tax start for fitness instructors?
The key date for many is April 2027, at £30,000 of gross income. Over £50,000 it applies now. Under £30,000, you may not be in scope until April 2028 at £20,000, which is still under government review.
I teach classes at several gyms, how do I keep records?
Each gym is a separate income source, but they all sit in one set of self-employed records. Clear Books totals them into a single quarterly update.
What if I'm both employed and self-employed?
Common for instructors. MTD covers your self-employed class income; PAYE employment is handled by your employer but still forms part of your final declaration.
Can I claim mileage between venues?
Yes. Travel between the gyms you teach at is generally deductible, whether you use the mileage flat rate or actual vehicle costs.
What else can I claim?
Typical costs include kit and equipment, music licences, insurance, qualifications and CPD, and mileage between venues.
