How to Choose an Accountant for Personal Trainers in the UK

A personal trainer's tax position turns on one question before any other: whether the gym is your employer or your landlord. Get that wrong and the expenses, the VAT and the filing dates all follow the wrong path. You deal with block-booked class fees, gym rental agreements, self-employed contractors covering your sessions, and VAT implications on monthly subscriptions that can catch you out. A generalist accountant who handles every trade under the sun will miss these details.

You need an accountant for personal trainers who understands the specific tax rules, expense categories, and business structures that apply to PTs. What follows is the status question first, because it decides everything else, then expenses, VAT and the filing dates.

Why Personal Trainers Need a Specialist Accountant

Personal training is a service business with unusual revenue patterns. You might take block payments for 12 sessions upfront, run monthly direct debits for class passes, and pay gyms a monthly rent or commission. Each of these has different tax treatments.

Block payments received in March for sessions delivered across April to June are not all taxable in March. They are deferred income. A general accountant might treat the full amount as turnover in the month received, overstating your profit and causing you to pay more tax than you owe.

Similarly, if you pay a gym a monthly licence fee of £800 to use their floor space, that is a straightforward business expense. But if you pay them a 40% commission on each session you deliver through their platform, the VAT treatment changes. A specialist accountant for personal trainers spots this immediately.

Sole Trader or Limited Company: Which Structure Fits a PT Business?

Most personal trainers start as sole traders. It is simple to set up, cheap to run, and you file one self assessment return each year. If you are earning under £50,000 profit per year and working solo, this is usually the right structure.

Once your profit passes £50,000, the tax maths changes. As a sole trader, you pay 40% income tax on earnings above £50,270 (2025/26 rates) plus 2% Class 4 National Insurance on profits above £50,270. As a limited company director, you can take a salary of £12,570 (no income tax, no NI) and draw the rest as dividends taxed at 10.75% up to the basic rate band and 35.75% above that (2026/27 rates).

Here is an illustrative example using 2025/26 tax rates. A personal trainer in Ipswich earning £70,000 profit as a sole trader would pay roughly:

• £12,570 personal allowance (tax-free)
• £37,700 at 20% basic rate = £7,540 income tax
• £19,730 at 40% higher rate = £7,892 income tax
• Class 4 NI: £2,262 (6% on £37,700 between thresholds, 2025/26 rate) + £395 (2% on £19,730 above £50,270)
• Total tax and NI: approximately £18,089

The same £70,000 profit through a limited company in 2025/26, taking £12,570 salary and £57,430 dividends:

• Corporation tax at 19% on £70,000 profit = £13,300
• No income tax or NI on the £12,570 salary
• Dividend tax: £500 allowance, then £57,430 at 8.75% = £5,025 (assuming basic rate band covers it)
• Total tax: approximately £18,325

On these 2025/26 figures, the sole trader pays approximately £236 less than the limited company director at this profit level. The position shifts in the company's favour as profit rises further, though by less than it used to. Those company figures use the 8.75% dividend rate that applied for 2025/26. For 2026/27 the dividend rates are 10.75% at the basic rate and 35.75% at the higher rate, which narrows the incorporation gap at every profit level, so the comparison has to be run on current-year figures rather than on a rule of thumb. Corporation tax on profits above £50,000 is also subject to marginal relief, raising the effective rate above 19%. An accountant for personal trainers can run the current-year calculation for your specific numbers and confirm the right time to incorporate.

If you are considering incorporation, our incorporation services page covers the process step by step.

VAT: The Trap Personal Trainers Fall Into Most Often

VAT registration is mandatory once your taxable turnover exceeds £90,000 in any rolling 12-month period. For personal trainers, that includes all your session fees, class fees, online coaching subscriptions, and nutrition plan sales. It does not include gym rental payments you make to a third party, because those are purchases, not sales.

The trap works like this. You run a bootcamp in a Chelmsford park. You take £95 per person per month. You have 85 clients. Your monthly turnover is £8,075. Over 12 months that is £96,900. You have crossed the VAT threshold without realising it.

Once you register, you must add 20% VAT to your prices unless your services are VAT exempt. Personal training services are standard-rated for VAT. That means your £95 bootcamp becomes £114 including VAT, or you absorb the VAT and keep £79.17 net. Either way, your pricing changes.

If you operate through a limited company and use the Flat Rate Scheme, you might pay a lower effective VAT rate. For personal trainers, check HMRC's published sector percentage at the point you apply, and note that a limited cost trader pays 16.5% regardless of sector, which makes the scheme pointless for most PTs. Check your eligibility before applying.

What Expenses Can a Personal Trainer Claim?

Personal trainers can claim a broad range of expenses, but HMRC looks closely at anything with personal use. Here is what typically qualifies:

• Gym floor rental or licence fees
• Equipment: kettlebells, resistance bands, mats, TRX, dumbbells, plyo boxes
• Insurance: public liability, professional indemnity, equipment cover
• First aid certification and CPD courses (fitness qualifications, nutrition diplomas)
• Travel between client sessions (not home to first client or last client to home)
• Phone and laptop (apportion for business use)
• Marketing: website hosting, social media ads, flyers, photography for your portfolio
• Clothing: only if it is branded with your business logo and not suitable for everyday wear. A plain black gym top is not a deductible expense. A top printed with "PT Business Name" is.
• Subscriptions: software like PT Distinction, My PT Hub, Trainerize, accounting software like Xero or FreeAgent

Equipment you will use for more than a year is a capital asset whatever it cost, and relief comes through capital allowances rather than as an ordinary expense. In practice the Annual Investment Allowance gives 100% relief in the year of purchase up to £1,000,000, so the cash effect is usually the same, but it has to be recorded in the right place on the return.

If you work from home, you can claim a proportion of your household bills. HMRC's simplified expenses give a flat £10 to £26 a month depending on the hours you work at home, or you can calculate the actual costs based on the number of rooms and hours used for business. The flat rate is simpler and usually sufficient for a PT who trains clients elsewhere.

Making Tax Digital for Personal Trainers

Making Tax Digital (MTD) for Income Tax Self Assessment becomes mandatory from April 2026 for self-employed individuals with qualifying income over £50,000. From April 2027, it drops to £30,000. From April 2028, it drops to £20,000.

If you are a sole trader personal trainer earning over £50,000, you must use MTD-compatible software from 6 April 2026. That means no more filling in the self assessment pages manually. You will need to submit quarterly updates to HMRC through software like Xero, QuickBooks, or FreeAgent, with a final declaration at year-end.

If you operate through a limited company, MTD for ITSA does not apply to you directly. Your company files corporation tax returns (CT600) through a different process. But if you also have self-employed income on the side, that income is caught by MTD.

Our bookkeeping and compliance blog has more detail on MTD deadlines and software choices.

IR35 and Personal Trainers Working Through a Limited Company

If you are a personal trainer who works exclusively through one gym or one platform, HMRC may argue you are a disguised employee for IR35 purposes. This matters if you operate through a limited company and take dividends instead of salary.

Most personal trainers are genuinely self-employed. You set your own hours, you decide which clients to take, you provide your own equipment, and you can send substitutes (another qualified PT) to cover your sessions. Those facts support a self-employed status.

But if your contract says you must attend every session personally, you cannot send a cover trainer, you wear the gym's branded kit, and you follow the gym's timetable, HMRC may argue you are inside IR35. In that case, the gym (if it is a medium or large business) must issue a Status Determination Statement and operate PAYE on your fees.

If you are unsure about your IR35 status, speak to an accountant who understands the off-payroll working rules. Our services page covers IR35 reviews as part of our limited company support.

Am I Employed or Self-Employed as a Personal Trainer?

It depends on whose clients you are training and who sets the terms. If the gym puts you on its payroll, schedules you into its classes, and hands you its members as your clients, you are an employee. Your pay arrives through PAYE (Pay As You Earn) with income tax and National Insurance already deducted, and you have no self-employed trade to report for that work.

If you pay the gym a licence fee or a floor rent so that you can train your own clients on its premises, you are self-employed. You set your prices, you keep the fees your clients pay you, you carry the risk of an empty diary, and the licence fee is a cost of your trade. That is the fork almost every dispute in this sector turns on, and job titles do not settle it. A gym can call you a freelance trainer on paper while treating you exactly like staff, and HMRC looks at what actually happens.

The signals that point to self-employment are the ones you would expect: your own clients, your own prices, your own kit, freedom to train elsewhere, and the ability to send another qualified trainer to cover a session. The signals that point to employment are the gym setting your rate, controlling your hours, supplying the clients, and requiring you personally to turn up.

Note that this is a different question from IR35, which only comes into play if you already run your training through your own limited company. Employed or self-employed is decided first, and for most personal trainers it is decided without a company being involved at all.

Is a Gym Licence Fee an Allowable Expense?

Yes. If you pay a gym for the right to train your own clients on its floor, that payment is a business cost and comes off your taxable profit. It does not matter whether the gym bills it as rent, a licence fee, a chair-equivalent bench fee, or a monthly platform charge. What matters is that you incur it in order to trade.

Percentage-of-takings arrangements work the same way. If the gym takes 30% of what each client pays you and passes on the remaining 70%, your turnover is the full amount the client pays and the 30% is a deductible expense. Recording only the net figure understates both sides and will make your VAT position look better than it is, which matters as you approach the £90,000 registration threshold.

Keep the agreement itself. A written licence or rental agreement is the cleanest evidence that you are paying for access rather than being paid by the gym, and it does double duty if your employment status is ever questioned.

Your own gym membership is a different matter, and the answer there is generally no: personal fitness spend serves you as a person as well as your trade, so it fails the wholly and exclusively test. Our guide to whether gym membership is tax deductible in the UK deals with that question, including the position where a company pays for a director's membership. For the wider list, see our allowable expenses checklist for sole traders.

Can You Be Employed at a Gym and Self-Employed at the Same Time?

Yes, and it is the most common shape in the industry. Working shifts on a gym's payroll during the day and training your own clients in the evenings gives you employment income and self-employment profit in the same tax year. Both go on one Self Assessment return, and each is taxed under its own rules.

Your employment is taxed through PAYE as you are paid. Your self-employed profit is taxed after the year ends, through Self Assessment, with Class 4 National Insurance on top. The two do not merge into one pot before tax is worked out, but they do stack for rate purposes, so the profit sits on top of the salary when the bands are applied. That is why trainers in this position are often surprised by the bill: the personal allowance is usually swallowed by the employment, so the first pound of PT profit is taxed at the basic rate rather than being free.

Here is how that works in practice, using the 2026/27 tax year. Lorraine works part-time on a gym's payroll in Exeter and trains her own clients in the evenings.

• Employment salary: £16,000, taxed through the gym's payroll
• Self-employed PT profit after the licence fee and her other costs: £14,000
• Personal allowance £12,570 set against the salary first, leaving £3,430 taxed at 20% = £686, already deducted by PAYE
• The full £14,000 of PT profit is therefore taxed at 20% = £2,800 income tax
• Class 4 National Insurance at 6% on the profit above £12,570: 6% of £1,430 = £85.80
• Self Assessment bill for the year: £2,800 plus £85.80 = £2,885.80

The personal allowance, the £12,570 and £50,270 bands and the Class 4 rates of 6% and 2% used here are the 2025/26 rates, still current when this page was checked in August 2026. Check the current-year figures before you rely on them.

There is a second bill hiding in that example. Because Lorraine's Self Assessment liability is over £1,000 and less than 80% of her total income tax was collected at source through PAYE, she also has to make payments on account towards the following year: two instalments of £1,442.90, one due with the balancing payment on 31 January and one on 31 July. Her first January as a self-employed trainer therefore costs £2,885.80 plus £1,442.90, not £2,885.80. Setting aside roughly a third of every PT fee as it comes in covers this comfortably.

One thing to watch on the employment side: your tax code. If the gym's payroll is operating an emergency or split code, or if a previous employer's figures are still attached to it, the PAYE deduction will not match the £686 in the example and your Self Assessment will square the difference up in whichever direction it falls.

If you are starting PT work alongside a job you are keeping, our guide on registering as self-employed while keeping a full-time job walks through the registration side.

When Does a Personal Trainer Have to Register with HMRC?

Once your gross trading income passes £1,000 in a tax year. Below that, the trading allowance covers you and there is nothing to report, which is why a trainer taking on two or three clients around a job often has no filing obligation in their first few months.

Gross means the total your clients pay you before you take off the gym's licence fee or anything else. A trainer billing £4,000 and paying £3,200 in floor fees has £4,000 of gross trading income, not £800, and is well past the trigger.

Once you are over £1,000, you choose between deducting the £1,000 allowance or deducting your actual expenses. It is one or the other, never both, and for most personal trainers actual expenses win easily because the gym fee alone usually exceeds £1,000. The allowance also cannot be used against money paid to you by your own employer, so a gym employee who picks up extra paid work from that same gym cannot shelter it this way.

The deadline is 5 October following the end of the tax year in which you crossed £1,000. Cross it in the year to 5 April 2027 and you register by 5 October 2027, with the return and payment due by 31 January 2028.

Making Tax Digital for Income Tax Self Assessment is measured on gross qualifying income rather than profit, so check your turnover against the April 2026, April 2027 and April 2028 thresholds of £50,000, £30,000 and £20,000 rather than the figure at the bottom of your accounts. Our Making Tax Digital deadline guide sets out what changes and when.

Can a Personal Trainer Claim Mileage Between Clients?

Yes, where you are travelling between clients or between training venues in the course of your work. From 6 April 2026 the approved mileage rates are 55p a mile for the first 10,000 business miles in the tax year and 25p a mile after that, up from the 45p that applied for 2025/26 and earlier years. Motorcycles are 24p throughout.

The journeys that do not count are the ones to and from a workplace you attend regularly enough for it to be your base. If you train at the same gym most days, the drive from home to that gym is ordinary commuting and is not claimable, whatever the mileage adds up to. For employed instructors, a venue counts as temporary only while attendance is expected to last 24 months or less and take up under 40% of working time. For a self-employed trainer the test is the ordinary wholly and exclusively one, but the same instinct applies: a gym you work from week in week out is your base, not a temporary site.

For a mobile trainer with no fixed base this usually leaves a healthy claim: the runs between clients across the day are business travel, and where your home is genuinely the base you work from, the first and last journeys can be too. A trip to a bootcamp site you visit occasionally counts as well. Where you train at the same gym most days, that gym is your base and the drive to it is commuting. Keep a log with the date, the journey and the mileage. A note in your phone updated the same week beats a reconstruction in January.

You can either use the approved rates or claim the actual running costs of the vehicle apportioned for business use, but you pick one method per vehicle and stick with it for as long as you have that vehicle. The approved rates are simpler and are usually the better answer for a car you also drive privately.

When to Hire an Accountant for Personal Trainers

You do not need an accountant when you are earning £15,000 from a few clients and filing a simple self assessment. You can use software like GoSimpleTax or do it manually through the HMRC portal. The cost of an accountant would outweigh the benefit.

You should hire an accountant when any of these apply:

• Your turnover approaches or exceeds the VAT threshold of £90,000
• You are considering moving from sole trader to limited company
• You have multiple income streams: PT sessions, online coaching, nutrition plans, merchandise
• You hire other trainers to work under your brand
• You rent commercial space to run your own studio
• You are unsure whether your expenses are correctly categorised
• HMRC opens a compliance check into your tax return

A good accountant saves you more than they cost. If they find one VAT error or one missed expense category, that can cover their annual fee.

What to Look for in an Accountant for Personal Trainers

Not all accountants are equal. Here is what to check before you hire one for your PT business:

• ACCA qualification or equivalent. Anyone can call themselves an accountant. Qualified accountants are regulated and carry professional indemnity insurance. Check that your accountant holds a recognised qualification before you commit.
• Experience with service businesses. Personal training is a service business with deferred income, block bookings, and variable VAT treatment. An accountant who only works with ecommerce or construction clients will not understand your revenue model.
• Software recommendations. A good accountant will recommend Xero, FreeAgent, or QuickBooks and help you set it up. They should not insist on paper records or spreadsheets.
• Fixed fee pricing. You should know what you are paying each month. Avoid accountants who charge by the hour for routine compliance work.
• Proactive advice. Your accountant should tell you about VAT thresholds before you hit them, not after. They should suggest incorporation when your profit justifies it. They should flag Making Tax Digital deadlines well in advance.
