Accountant for Personal Trainers UK — Simplr Accounting

Accountant for
Personal Trainers.

Specialist UK accountants for personal trainers — gym floor sessions, online coaching, group classes and digital programmes.

Whether you earn from one-to-one sessions, an online coaching platform, group classes or selling digital plans, we keep your accounts HMRC-compliant, your tax and expenses handled correctly and your Self Assessment filed on time. We understand how PT income is taxed — gym rent, coaching apps, DAC7 platform reporting and everything in between.

01 / Why Simplr

We get how personal trainers actually earn.

Most accountants see fitness income and file it as simple self-employment. We know the reality — gym licence fees, online coaching platforms, group class income, digital product sales, brand sponsorships and DAC7 reporting all need handling correctly.

01

Fitness business specialists

Gym floor sessions, online coaching, group classes, digital plans, affiliates and sponsorships — we understand every income stream and exactly which PT expenses you can claim.

02

Gym rent and licence fees

Gym floor rent, PT licence fees and studio hire are all fully deductible business expenses. We make sure every facility cost is captured correctly alongside your session income.

03

Online coaching platforms

Coaching apps now share income data with HMRC under DAC7 reporting rules — just like eBay and Airbnb. We make sure your declared income matches what HMRC already sees, so there are no discrepancies.

04

Quick support

Got a question between clients about whether new kit, a CPD course or a coaching app subscription is claimable? Message us on WhatsApp and get a reply within 24 hours — no extra charges, ever.

05

Making Tax Digital

Earning over £50,000 from your PT business? MTD for Income Tax applies from April 2026. We set up digital records and handle all quarterly submissions for you.

06

Fixed monthly fees

No hourly rates, no surprise invoices. A clear monthly fee that covers everything — you know the cost from day one regardless of how your income is structured.

02 / How we help

Everything a personal trainer needs.

From your first Self Assessment to ongoing bookkeeping, VAT, limited company accounts and tax planning — we handle the financial side so you can focus on growing your client list and scaling your coaching.

03 / Expenses

Every cost you can claim.

PT businesses have a wide range of genuine claimable costs — and some specific rules that catch people out. Read our full guide to how personal trainers should handle tax and expenses for the complete breakdown.

Gym rent or PT licence fees
Equipment — weights, mats, cables, resistance bands, TRX, foam rollers
Branded uniform (not generic gym wear)
PT qualifications and CPD courses
Professional and public liability insurance
Coaching app subscriptions
Music licensing fees
Mileage between clients and locations
Phone and internet (business proportion)
Website and marketing costs
Video and content creation equipment
Accountancy fees and bookkeeping software
Gym clothing and HMRC

The branded kit rule

HMRC does not allow claims for everyday gym clothing, even if you only wear it at work — because it could in theory be worn elsewhere. The exception is clothing that is branded with your business name or logo, or genuine protective equipment. Branded kit and shoes clearly for business use are claimable. Generic activewear is not, even if you bought it specifically for work.

Online coaching platforms and DAC7

HMRC can already see your platform income

Many coaching apps and platforms now share seller income data with HMRC under DAC7 reporting rules — the same rules that apply to eBay, Airbnb and Etsy. This means HMRC may already have a record of your online coaching income before you file. Read our guide to personal trainer income streams and how they are taxed for more on what to declare and when.

Going limited

When does a limited company make sense?

Many PTs start as sole traders and it is often the right structure early on. A limited company can become significantly more tax-efficient as profit grows — particularly once you are earning a consistent six-figure income from a mix of coaching and online products. Read our guide to how personal trainers can save tax through a limited company, or book a call and we will run the numbers for your specific situation.

04 / Key thresholds

Know where
you stand.

Whether you are just starting out with your first clients or running a six-figure online coaching business, these thresholds shape how you report and pay tax in the UK.

HMRC also has official guidance on how to register for Self Assessment if you have not yet done so.

£1k
Trading allowance
Once your gross PT income exceeds £1,000 in a tax year, you need to register as self-employed with HMRC and file a Self Assessment return — even if you also have a PAYE gym job.
£12.5k
Personal allowance
You only pay Income Tax on profit above your Personal Allowance. Every allowable expense claimed reduces your taxable profit — and your tax bill.
£50k
MTD Income Tax threshold
If your qualifying self-employed income exceeds £50,000, Making Tax Digital applies from April 2026 — digital records and quarterly updates required.
£90k
VAT registration
Once taxable turnover from PT sessions, online coaching and product sales exceeds £90,000 in a rolling 12-month period, VAT registration is mandatory.

06 / FAQs

PT tax questions, straight answers.

Everything you need to know before booking a call.

Do personal trainers pay tax in the UK?
Yes. If you are working as a self-employed PT in the UK, your earnings are taxable income. Once you earn over £1,000 in a tax year, you need to register as self-employed with HMRC and file a Self Assessment tax return. This applies whether you coach full-time, alongside a PAYE gym job, or as a side hustle. Read our guide to personal trainer income streams and how they are taxed.
What income do I need to declare as a personal trainer?
All of it. One-to-one session fees, online coaching subscriptions, group class income, digital plan sales, sponsorships, affiliate commissions and any branded merchandise sales. You report gross income then deduct allowable expenses to calculate your taxable profit.
What expenses can personal trainers claim?
Gym rent or licence fees, equipment (weights, mats, cables, resistance bands, TRX, foam rollers), branded uniform (not generic gym wear), PT qualifications and CPD courses, professional insurance, coaching app subscriptions, music licensing, mileage between clients, phone and internet, website and marketing costs, and accountancy fees. Read our full personal trainer tax and expenses guide.
Can I claim my gym clothing?
Only if it is branded with your business name or logo, or is genuine protective equipment. HMRC does not allow claims for everyday clothing, even if you only wear it for work, because it could in theory be worn elsewhere. Branded kit and shoes clearly for business use are claimable. Generic activewear is not.
Do personal trainers need to register for VAT?
If your taxable turnover exceeds £90,000 in any rolling 12-month period, yes. PT services, online coaching and physical product sales all count towards that threshold. We handle registration and quarterly submissions so you stay compliant. See HMRC's guidance on VAT registration for the rules.
Should I set up a limited company for my PT business?
Many PTs start as sole traders and it is often the right structure early on. As income grows — particularly from online coaching and digital products alongside in-person sessions — a limited company can become significantly more tax-efficient. Read our guide to how personal trainers can save tax through a limited company, or book a call and we will run the numbers for you.
What is Making Tax Digital and does it affect me?
Making Tax Digital for Income Tax requires self-employed people with qualifying income over £50,000 to keep digital records and submit quarterly updates to HMRC from April 2026. If your PT income exceeds that threshold, it will apply. Visit our Making Tax Digital page for more detail, or book a call and we will confirm your position.
Is my information kept private?
Absolutely. We are bound by strict professional confidentiality rules and GDPR. Your financial information is stored securely in encrypted, cloud-based software. We will never share your data with anyone without your explicit permission.
