Allowable expenses, clinic room rent, mobile mileage, insurance and CPD, VAT and MTD for Income Tax explained for self-employed sports and remedial massage therapists.
A sports massage therapist runs a hands-on, low-margin trade where the costs are small but constant. You are not buying expensive machinery; you are getting through litres of oil, rolls of couch paper, boxes of kinesiology tape and washing machine loads of towels, while paying rent for a treatment room or fuel to drive between clients. Add professional indemnity insurance, governing-body membership and the CPD you need to keep your accreditation, and the deductions add up to a meaningful slice of income, as long as you record them as they happen.
This guide is built around how a self-employed therapist actually earns and spends: cash and card payments from a steady book of clients, often a mix of clinic-based and mobile work, sometimes alongside a part-time PAYE job at a gym or physio practice. Get the day-to-day bookkeeping right and the annual return becomes a formality.
As a sole trader you pay Income Tax on profit, which is your total treatment income minus allowable expenses. For 2025/26 the personal allowance covers the first GBP 12,570, then you pay 20% to GBP 50,270, 40% to GBP 125,140 and 45% above, with the personal allowance tapering away between GBP 100,000 and GBP 125,140 to create an effective 60% band. Class 4 National Insurance is 6% on profit between GBP 12,570 and GBP 50,270 and 2% above, with Class 2 NIC settled through Self Assessment.
Scottish therapists pay Scottish Income Tax on their profit through six bands (19%, 20%, 21%, 42%, 45% and a 48% top rate) and carry an S-prefixed tax code, while National Insurance stays UK-wide. Welsh therapists have a C-coded tax code at rates currently matching the rest of the UK. If you also have a PAYE job at a gym, leisure centre or clinic and your code looks wrong, run it through the tax code checker so the day job is not quietly distorting your allowance.
Many therapists begin part-time, taking a handful of clients in the evenings around a salaried job or while finishing qualifications. The GBP 1,000 trading allowance is built for exactly this. If your gross self-employed income from treatments is GBP 1,000 or less in a tax year, it is tax-free and you do not need to register for Self Assessment for it. Cross GBP 1,000 and you must register and report the full amount, even if it is a sideline.
Once over the threshold you choose each year. You can deduct the flat GBP 1,000 trading allowance instead of working out actual expenses, which suits a therapist whose only outlay is a little oil and tape. Or you can deduct your real allowable expenses if they come to more than GBP 1,000, which is usually the case once you are paying room rent, insurance and mileage. You cannot do both, so total your costs and pick whichever leaves the lower profit. If you are still treating treatments as a sideline, our guide to side hustle income covers when occasional earnings tip into a taxable trade.
An expense is allowable when incurred wholly and exclusively for the business. The therapist's list is dominated by consumables, room rent, insurance and travel rather than big equipment buys.
| Expense | What qualifies | Notes |
|---|---|---|
| Treatment couch and equipment | Portable or fixed couch, bolsters, head rest, stool, heat lamp | Larger items usually claimed in full via the Annual Investment Allowance |
| Hands-on tools | Foam rollers, trigger-point and massage tools, kinesiology and rigid tape, theragun-style devices | Fully deductible business kit |
| Consumables | Massage oil, balm, wax, couch roll, hand sanitiser | Recurring cost, keep the receipts |
| Towels and laundry | Towels, sheets, blankets and the cost of washing them | A real, regular cost that is easy to forget |
| PPE and hygiene | Gloves, sanitiser, cleaning products, disposable face covers | Allowable where used for the trade |
| Professional indemnity insurance | Cover required to treat clients legally and safely | Fully deductible and usually annual |
| Room or clinic rent | Chair or room rent at a gym, clinic or sports club | One of the largest deductions for clinic-based therapists |
| Mobile travel | Mileage between clients, or actual vehicle running costs | Commuting to a fixed base is not allowable |
| Professional membership | SMA, CThA, FHT, ISRM and similar bodies | Allowable where relevant to the trade |
| CPD and training | Accredited courses that update existing skills | Initial qualification before trading is not allowable |
| Software and admin | Online booking, card reader fees, website, a share of home admin costs | Deduct the business proportion |
| Accountancy and bank fees | Bookkeeping, Self Assessment, business banking | Fully deductible |
If you travel to clients, mileage is often a substantial deduction. Under HMRC simplified mileage you claim 45p per mile for the first 10,000 business miles in the tax year and 25p a mile thereafter, which covers fuel, insurance, servicing and wear. Alternatively you can claim the actual business proportion of running costs, but you must stick to one method for a given vehicle. Travel from client to client during the working day is allowable; ordinary commuting from home to a gym where you rent a fixed room is not. Keep a simple mileage log with dates, destinations and the business reason. If you also earn from rentals or other work, the multiple-income tax calculator helps you see how the streams stack up.
Clinic-based therapists usually pay to rent a room or a treatment slot at a gym, physio practice or sports club, and that rent is fully deductible. If you treat clients at home, you cannot claim rent against yourself, but you can claim a fair proportion of household running costs for the space and time used, or use HMRC's simplified flat rate based on hours worked at home. Either way, keep the basis of your apportionment reasonable and consistent.
The private share of dual-use costs, such as a phone or car also used personally, must be excluded. Your initial diploma or qualification taken before you started trading is not allowable, because it brings a new skill into being rather than updating an existing one; only CPD that maintains or extends your current practice qualifies. Everyday clothing is never allowable even if you wear a polo shirt with your business name on it, although genuinely protective items can be. Gym membership you use partly for your own fitness is not deductible.
Take a therapist who splits the week between a rented clinic room and mobile visits to a local rugby club, with total treatment income of GBP 34,000 for the year.
Income: GBP 34,000 (clinic clients GBP 22,000, mobile and club work GBP 12,000)
Allowable expenses:
Taxable profit: GBP 34,000 minus GBP 11,000 = GBP 23,000
Income Tax: GBP 23,000 minus GBP 12,570 = GBP 10,430 at 20% = GBP 2,086
Class 4 NIC: GBP 10,430 at 6% = GBP 626
Total tax and NIC: GBP 2,712 for the year. A new couch bought outright that year would normally be claimed in full under the Annual Investment Allowance, cutting profit further. Run your own figures through the sole trader tax calculator to see where you land.
For a hands-on therapist, tax is won on the small stuff: log every mile, keep every receipt for oil, tape and laundry, and bank the rent paid for your room. Those tiny costs add up to a real deduction.
The trap for a busy therapist is cash and contactless income that never gets written down. A client pays GBP 45 by card, the next pays GBP 40 cash, and by Friday three sessions have vanished from memory. Capture income the day it is earned, not at year end. A short daily routine, logging each treatment fee and snapping a photo of any receipt, beats a January scramble through bank statements and shoeboxes.
Use a dedicated business bank account or at least a separate card so personal and business money never mix, reconcile your card reader and cash takings weekly, and keep a running mileage log in your phone. Under the accruals basis a session given in March but paid in April still belongs to the year you did the work, so do not let late payers drift into the wrong tax year. Strong daily records are also exactly what Making Tax Digital will require.
You must register for VAT once taxable turnover exceeds GBP 90,000 in any rolling 12-month period, which most solo therapists never approach. An important point for this trade: sports and remedial massage is generally standard-rated, not VAT-exempt. The healthcare exemption applies only to services provided by professionals on a statutory register, and most sports massage therapists are not registered health professionals, so treatments count toward the VAT threshold. If your turnover climbs toward GBP 90,000, perhaps because you employ associates or run a busy multi-room clinic, plan ahead, because adding 20% to consumer prices usually eats into your margin rather than being passed on cleanly.
Making Tax Digital for Income Tax Self Assessment replaces the once-a-year return with quarterly digital submissions and a year-end finalisation. The thresholds are based on gross income, not profit:
For a therapist this rewards the good daily habits above. Instead of pulling a year of card takings and cash together each January, you record income and costs digitally as they happen and send HMRC a quarterly summary using compatible software. The steady, repetitive nature of treatment income actually makes the quarterly rhythm easy once a simple routine is in place. Our guide to MTD for sole traders walks through what the quarterly cycle looks like in practice.
Not registering once over GBP 1,000. The trading allowance is a threshold, not a free pass at any income level. Cross it and you must register for Self Assessment, even if treatments are a sideline.
Under-recording cash and card income. The money you forget to bank in your records is the costliest error of all. Log every session fee the day it is earned.
Forgetting consumables and laundry. Oil, tape, couch roll and towel washing are small individually but add up to hundreds of pounds a year of legitimate deductions.
Claiming the wrong mileage. Commuting to a fixed rented room is not deductible; only client-to-client travel and trips away from your base are. Keep a log to back it up.
Assuming massage is VAT-exempt. Sports massage is generally standard-rated, so all of it counts toward the GBP 90,000 VAT threshold if your clinic grows.
