Personal Trainer Tax UK 2026/27: Self-Employed, Gym Rent and Expenses

Employment Status: Gym-Based vs Employed Instructors

Personal training sits across two very different tax categories. A gym-employed fitness instructor on a payroll, paid a wage or salary with tax deducted under PAYE, is simply an employee. A freelance PT who pays the gym a weekly floor-rent fee or a per-session access charge, sets their own client rates, and builds their own client book is normally self-employed. The distinction matters because it changes who deducts tax, what expenses can be claimed, and how National Insurance is calculated.

Some gyms operate a hybrid model — a lower base retainer plus commission — which can blur the line. As with other chair-rent style trades, HMRC looks at control (who sets prices and hours), financial risk (who bears the loss if a client cancels) and substitution (can you send another trainer in your place) to determine genuine status, not just the label on the contract.

Allowable Expenses for Self-Employed Trainers

• Gym floor rent or studio hire — fully deductible.
• Professional insurance — public liability and professional indemnity cover, often mandatory for working in a gym.
• CPD courses that maintain or extend existing qualifications (nutrition add-ons, specialist strength & conditioning modules).
• REPs/CIMSPA annual registration and first aid recertification.
• Small equipment — resistance bands, kettlebells, a portable speaker for outdoor sessions.
• Booking and payment software subscriptions (client management apps, calendar tools).
• Marketing — website, social media content, business cards.
• Workwear branded with a business logo (plain gym clothing without branding generally doesn't qualify, as it's treated as ordinary clothing you could wear anywhere).

Mileage for Outdoor and Mobile PTs

Trainers who run bootcamps in parks, visit clients at home, or split time between two or three gym sites can claim HMRC's approved mileage rate — 45p per mile for the first 10,000 business miles each tax year, then 25p per mile after that — for travel between these temporary workplaces. A single fixed gym you attend every day for every session is treated more like ordinary commuting and isn't normally claimable, so the pattern of your working week matters.

VAT and Growing PT Businesses

A one-to-one PT charging, say, £40-£70 a session rarely approaches the £90,000 VAT registration threshold on their own. But personal trainers who scale into online coaching — selling programmes, subscriptions, or group coaching at volume — can cross that threshold faster than session-based work alone would suggest, because digital products often carry lower delivery costs and higher margins per client. It's worth tracking rolling 12-month turnover monthly once a coaching business starts to grow, since registration is compulsory once you cross the threshold, not optional.

National Insurance and Structuring the Business

Self-employed personal trainers pay Class 4 NI at 6% on profits between £12,570 and £50,270, and 2% above that, alongside income tax at standard rates. Class 2 has effectively been abolished for those with profits above £7,105, with voluntary Class 2 payments at £3.65 a week remaining the cheapest way to protect State Pension entitlement for those below it.

A limited company is rarely worthwhile for a solo PT with modest profits, given the extra accountancy and filing burden, but can become attractive once a trainer builds a coaching brand with multiple income streams — online programmes, affiliate income, in-person sessions — pushing profits well past £40,000-£50,000 a year.
