Gym rent, online coaching, equipment and kit: everything a self-employed PT needs to know about tax, including the Scottish bands and MTD for Income Tax.
Personal training has quietly become one of the most varied self-employed trades for tax, because a modern PT rarely has just one income stream. There is the in-person session income, the gym you pay to train clients in, the online coaching programme, the app subscriptions, the affiliate links and the occasional sponsored post. HMRC treats every one of those as part of the same trade, and the area where PTs most often slip up is the line between a genuine business cost and a personal one, especially around gym membership and clothing.
This guide is for self-employed personal trainers working in a gym, outdoors, in clients' homes or fully online, and it covers the expenses that actually apply to the job, the Scottish and Welsh tax differences (because PTs work everywhere), VAT and the move to Making Tax Digital.
You are a sole trader paying Income Tax and Class 4 National Insurance on your profit, total income minus allowable expenses, on a Self Assessment return filed by 31 January each year. Whether a client pays you cash after a session, a gym passes on your share, or an online platform deposits monthly subscriptions, no tax is deducted at source; the liability is entirely yours.
For 2025/26, if you are taxed in England, Wales or Northern Ireland:
If you also coach part-time as an employee at a gym, your PAYE tax code may already use part of your personal allowance, so check it with HMRC's tax code checker to avoid an unexpected balancing payment. Estimate your overall bill with the sole trader tax calculator.
Income Tax on earned income is devolved to Scotland, and a Scottish taxpayer pays Income Tax on self-employment profit at the Scottish bands, which for 2025/26 run across six rates: a 19% starter rate, a 20% basic rate, a 21% intermediate rate, a 42% higher rate, a 45% advanced rate and a 48% top rate, applied to progressively higher slices of income above the GBP 12,570 personal allowance. The thresholds differ from the rest of the UK, so a higher-earning Scottish PT can pay more on the same profit than a counterpart in England. Your tax code will carry an S prefix. Welsh taxpayers carry a C prefix; Wales has the power to set its own rates but currently mirrors England. National Insurance and the personal allowance remain UK-wide.
| Expense | Notes |
|---|---|
| Gym rent / licence to train | Rent or a "licence to train" fee paid to a gym so you can deliver paid sessions there. Fully allowable. |
| REPs / CIMSPA registration and insurance | Professional register membership and public liability / professional indemnity insurance. Allowable. |
| Equipment | Kettlebells, mats, resistance bands, suspension trainers, spin bikes, heart-rate monitors used with clients. Larger items may go through the Annual Investment Allowance. |
| First aid and CPD | First-aid certification, nutrition courses, new training qualifications that update existing skills. |
| Online platform and app fees | Coaching app subscriptions, video hosting, scheduling and payment-processing fees. |
| Mileage (mobile / outdoor PTs) | 45p/mile for the first 10,000 business miles travelling to clients or outdoor session locations; home-to-fixed-gym commuting is not allowable. |
| Branded clothing | Kit carrying your business logo, and genuine protective equipment. Ordinary sportswear and trainers are not allowable. |
| Marketing | Website, social media ads, photography for promotion, branded materials. |
| Use of home as office | A reasonable proportion of household costs for admin, programme writing and online coaching delivered from home. |
This is the mistake PTs make most. A personal gym membership you use for your own workouts is not deductible, because it is not incurred wholly and exclusively for the business; you would arguably train anyway. What is deductible is a fee that lets you earn, a licence-to-train arrangement, a rented studio space, or a day-rate to use a facility for client sessions. If a single payment covers both your own use and your right to train clients, only the genuine business element is allowable, and you should be ready to justify the split.
PTs routinely try to claim their training wardrobe and are routinely wrong. HMRC's long-standing position is that ordinary clothing, including everyday sportswear and trainers, is not allowable even if you only wear it for work, because it also provides warmth and decency. The exceptions are clothing that carries your business logo as a uniform, and genuine protective equipment. Your general leggings and running shoes do not qualify, however much they are "only for sessions".
Take a trainer who delivers gym sessions and runs a small online coaching programme, turning over GBP 36,000 in 2025/26 (GBP 26,000 in-person, GBP 10,000 online), driving 6,000 business miles to outdoor and home sessions.
Income: GBP 36,000
Allowable expenses:
Total expenses: GBP 13,632
Taxable profit: GBP 36,000 minus GBP 13,632 = GBP 22,368
For a trainer taxed in England:
Income Tax: GBP 22,368 minus GBP 12,570 = GBP 9,798 at 20% = GBP 1,960
Class 4 NIC: GBP 9,798 at 6% = GBP 588
Approximate tax and NIC: GBP 2,548 for the year. A Scottish PT on the same profit would pay slightly more once the 21% intermediate rate bites on part of the income. Run your own numbers in the sole trader tax calculator, and use the mileage calculator to value your travel to clients.
The modern PT's accounts can look like several small businesses stitched together: cash and card from in-person sessions, recurring online subscriptions, one-off plan sales, affiliate payouts and occasional sponsorship. HMRC treats the whole lot as one trade, but you should still track each stream separately so you can see what is actually profitable. Online subscriptions and card payments leave a clean digital trail; the weak points are usually cash sessions and equipment bought with a personal card. Note every cash payment as it happens and photograph equipment receipts, because reconstructing a year of small purchases in January is where deductions get lost.
If a slice of your income is sponsorship or affiliate revenue rather than coaching fees, remember it is still taxable trade income, and the costs of producing that content (a portion of your phone, camera or editing software) are allowable in the same proportion as their business use. Keep the sponsorship contracts and affiliate statements with your session records so the full turnover picture is defensible if HMRC asks.
Personal training services are standard-rated, so the only reason most PTs do not charge VAT is that they sit below the GBP 90,000 registration threshold. The trainers who creep towards it are usually the ones who have scaled an online programme, large group classes, or product and supplement sales. Because those streams add to your taxable turnover, a successful PT can reach GBP 90,000 faster than expected. Once you cross it you must register within 30 days and charge 20% VAT on sessions and programmes, while gaining the ability to reclaim VAT on equipment, platform fees and other costs. Monitor your rolling 12-month total if your online side is growing quickly.
Making Tax Digital for Income Tax replaces the annual return with quarterly digital updates plus a final declaration. The dates are April 2026 for self-employment income over GBP 50,000 and April 2027 over GBP 30,000, with a planned extension to GBP 20,000 from April 2028. With both in-person and online income now common, a busy PT can sit above GBP 30,000 and fall into the second wave. Because your online subscriptions and card payments are already digital, the main task is recording cash sessions and equipment purchases promptly rather than reconstructing the year in January. Our MTD for sole traders guide explains what quarterly filing involves.
1. Claiming personal gym membership. Your own workouts are not a business cost. Only a fee that lets you deliver paid sessions, a licence to train or rented space, is allowable.
2. Claiming the training wardrobe. Ordinary sportswear and trainers fail the wholly-and-exclusively test. Only logo-branded kit and genuine PPE qualify.
3. Forgetting online and affiliate income. App subscriptions, downloadable plans, affiliate commissions and sponsorship are all taxable. Platforms increasingly report to HMRC, so omissions show up.
4. Getting the Scottish bands wrong. Scottish taxpayers have six rates with different thresholds; using the English bands can leave a higher-earning Scottish PT under-providing for their bill.
5. Mixing commuting with business travel. Driving to a fixed gym where you mostly work is commuting and not allowable. Travel to clients' homes and outdoor session locations is.
The cleanest way to think about a personal trainer's expenses: does this payment help me earn, or does it just help me train myself? The first is usually allowable; the second almost never is.
