Allowable expenses, mileage and mobile-business costs, equipment and CPD, insurance, VAT and MTD explained for UK self-employed equine and animal therapists.
The tax picture for a self-employed equine therapist is shaped by the road, not the desk. Whether you practise physiotherapy, sports massage, McTimoney-style manipulation, photizo or laser therapy, your working day is spent driving between livery yards, competition venues and private stables, carrying a boot full of equipment to treat horses where they live. That mobile, hands-on pattern decides what you can claim: vehicle and mileage costs dominate, your kit and insurance come next, and there is very little of the rent-and-utilities overhead that office-based trades carry.
This guide is built around how equine and animal therapists actually earn and spend: lots of small client invoices, heavy business travel across rural routes, specialist equipment that wears out, and the insurance and registration that let you work on someone else's horse at all. Get the mileage log and expense records right as you go, and Self Assessment becomes a quick year-end tidy-up rather than a scramble.
As a sole trader you pay Income Tax on your profit, which is total therapy income minus allowable expenses, not on everything you invoice. 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, while Class 2 NIC is settled through Self Assessment and protects your State Pension record.
Therapists in Scotland 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 hold a part-time PAYE job at a yard or veterinary practice, that employment can distort your code, so run it through the tax code checker if the figures look off.
Many therapists build a round slowly, treating a handful of horses around a part-time yard role or another job before going full-time. The GBP 1,000 trading allowance suits this start-up phase. If your gross self-employed income from all sources is GBP 1,000 or less in a tax year, it is tax-free and you do not need to register for Self Assessment. Cross GBP 1,000 and you must register and report the full amount.
Once over the threshold you have a choice each year. You can deduct the flat GBP 1,000 trading allowance instead of working out actual expenses, or deduct your real allowable costs if they come to more than GBP 1,000. You cannot do both. For an equine therapist the actual-cost route almost always wins, because a single competition weekend of travel plus your insurance and equipment usually blows past GBP 1,000 on its own. Total your costs and pick whichever leaves the lower profit.
An expense is allowable when incurred wholly and exclusively for the business. The therapist's list is dominated by travel, equipment, insurance and CPD rather than premises.
| Expense | What qualifies | Notes |
|---|---|---|
| Business mileage | Driving to yards, stables, competitions and client visits | Simplified 45p/25p per mile, or actual costs plus capital allowances |
| Therapy equipment | Massage units, laser and photizo machines, PEMF rugs, tens, supports, treatment tables | Larger items via Annual Investment Allowance |
| Consumables | Gels, tapes, liniments, cleaning and disinfectant supplies, gloves | Fully deductible when used on clients |
| Professional insurance | Public liability, professional indemnity and treatment-risk cover | Essential and fully allowable |
| Memberships and registration | NAVP, IAAT, ACPAT, McTimoney, RAMP register and similar bodies | Allowable where relevant to your trade |
| CPD and training | Courses that update or extend your existing therapy skills | New, unrelated qualifications are not allowable |
| Work clothing and PPE | Steel-toe boots, yard-branded workwear, gloves, hi-vis | Protective and branded kit only, not everyday clothes |
| Phone and software | Business phone, booking and diary apps, mileage tracker | Claim the business proportion |
| Home-office costs | Flat-rate working-from-home allowance or a fair proportion of bills for admin and storage | Choose the larger fair deduction |
| Accountancy and bank fees | Bookkeeping, Self Assessment, business banking | Fully deductible |
For a mobile equine therapist the vehicle is the single biggest cost driver, and you must choose one of two methods per vehicle. Most therapists use HMRC simplified mileage: 45p per mile for the first 10,000 business miles in the tax year, then 25p per mile beyond that. This single rate covers fuel, insurance, servicing, repairs and depreciation, so you do not claim those separately. It needs only a tidy log of dates, destinations and miles, which a phone app captures automatically.
Alternatively you can claim the business proportion of actual running costs (fuel, insurance, road tax, MOT, repairs) plus capital allowances on the vehicle itself. This can beat simplified mileage if you run a thirsty van or 4x4 to reach remote yards in winter, but it demands full records and a defensible business-use percentage. Use HMRC simplified expenses only once you have compared both. Travel between your home base and clients counts as business travel for a genuinely mobile trade; pure private journeys never do.
The private share of dual-use phone, broadband and vehicle costs must be excluded. Everyday clothing is not allowable even if you wear it for yard work; only protective boots and genuinely branded workwear qualify. Your own horse's keep, feed or vet bills are private unless the animal is demonstrably a business asset such as a demonstration horse. And the cost of your original therapy qualification, gained before the business started, is treated as personal training rather than a deductible expense, though CPD that updates those skills once you are trading is allowable.
Equine therapists often blend several income types, and they are not all taxed the same way. Use the multiple-income tax calculator to see how the streams stack on top of one another.
| Income type | How it is usually taxed | Watch out for |
|---|---|---|
| Therapy and treatment fees | Self-employment trading income | Record the gross fee even when paid by bank transfer or cash |
| Block-booking packages | Trading income, often paid upfront | Tax the income when earned, not all at the date received if it spans the year-end |
| Competition and event cover | Trading income | Travel and overnight costs to the venue are deductible |
| Selling rugs, supports or supplements | Trading income | Track stock and the cost of goods sold separately |
| Yard or veterinary PAYE work | Employment income, taxed at source | Your tax code may already use your personal allowance |
| Teaching, clinics and workshops | Trading income | Travel to deliver the session is deductible; commuting is not |
The recurring mistake is assuming a PAYE day job leaves your therapy income tax-free up to the allowance. If a yard or clinic salary already uses your GBP 12,570 personal allowance, every pound of therapy profit is taxed from the basic rate up, so set money aside accordingly.
For a mobile equine therapist, the mileage log is the most valuable document you keep. Record every yard visit as you make it, and the biggest deduction of the year looks after itself.
Take a full-time mobile equine sports therapist covering a rural patch, invoicing GBP 32,000 of fees across private clients, yards and a few competition weekends.
Income: GBP 32,000 (treatments GBP 26,000, event cover GBP 4,000, support and rug sales GBP 2,000)
Allowable expenses:
Taxable profit: GBP 32,000 minus GBP 8,850 = GBP 23,150
Income Tax: GBP 23,150 minus GBP 12,570 = GBP 10,580 at 20% = GBP 2,116
Class 4 NIC: GBP 10,580 at 6% = GBP 635
Total tax and NIC: GBP 2,751 for the year, plus Class 2 NIC settled through Self Assessment. Note how mileage alone is the largest single deduction, which is typical for this trade. Run your own figures through the sole trader tax calculator to sanity-check what to set aside.
The therapist's records live and die on two things: a clean mileage log and prompt capture of every fee. Because much of the income can be cash or bank transfer from individual horse owners, it is easy to under-record turnover, which is a far bigger risk than missing an expense. Note each treatment as you invoice it, snap a photo of equipment and fuel receipts at the point of purchase, and keep your mileage app running so the year-end total is already there. Keep records for at least five years after the 31 January filing deadline, and separate any retail stock so your cost of goods sold is clear.
You must register for VAT once taxable turnover exceeds GBP 90,000 in any rolling 12-month period, which most solo therapists never approach. Equine therapy services do not enjoy the medical exemption that applies to some human healthcare, so once you cross the threshold your fees become standard-rated. Because many clients are private horse owners who cannot reclaim VAT, registration effectively raises your prices or eats your margin. Weigh that against the VAT you could reclaim on equipment and your vehicle before registering voluntarily, and keep an eye on the rolling 12-month total if you take on yards, sell more retail stock or add associates.
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 busy mobile therapist this is largely a habit change. Instead of pulling a year of treatment invoices and mileage together each January, you record income and costs digitally as you go and send HMRC a quarterly summary using compatible software. The upside is that the steady drip of small treatment fees, which is exactly what makes a therapist's return fiddly, becomes far easier when captured continuously rather than reconstructed from a shoebox. Our guide to MTD for sole traders walks through what the quarterly rhythm looks like in practice.
Not keeping a mileage log. Without dates, destinations and miles you cannot evidence your single largest deduction, and HMRC can disallow an estimated figure.
Under-recording cash and transfer fees. Income from individual horse owners is easy to miss; record the gross fee for every treatment as it is earned.
Switching mileage methods mid-vehicle. Once you claim simplified mileage on a vehicle you must keep that method until you change the vehicle. Decide up front.
Claiming everyday clothing. Only protective boots, gloves and genuinely branded workwear are allowable; ordinary yard clothes are not.
Assuming a PAYE job shields therapy income. If a yard or clinic salary already uses your personal allowance, your therapy profit is taxed from the basic rate up, so set aside more than you expect.
