Key takeaways
- VAT registration bites at £90,000 of taxable turnover on a rolling twelve-month test; about eleven £180 appointments a week gets you there.
- Cosmetic treatments are standard-rated; the medical exemption applies only where the principal purpose is protecting or restoring health, judged treatment by treatment.
- HMRC actively challenges blanket 'it's all medical' claims, and aesthetics VAT disputes have already reached tribunal (cases reported up to around 2022).
- Crossing the threshold and holding prices hands HMRC roughly a sixth of takings, so plan with an accountant before £70,000, not after £90,000.
- Clinic income alongside NHS PAYE needs self-assessment registration by 5 October following your first trading tax year.
Eleven appointments a week at an average of £180 is £95,040 a year (worked arithmetic: 11 x £180 x 48 working weeks). The VAT registration threshold is £90,000 of taxable turnover (HMRC, checked 11 July 2026). Most aesthetic practitioners meet those two numbers in the wrong order, discovering the second only after the first has been true for months.
This guide covers the threshold, the medical exemption as it actually operates, the records that survive scrutiny, and the tax basics of running a clinic alongside NHS employment. It is written for practitioners rather than accountants, and it ends by telling you to hire one.
What counts towards £90,000
Taxable turnover means your takings from VAT-taxable supplies, not your profit. Product costs, room rent and your own drawings are irrelevant to the test; a clinic taking £95,000 and keeping £30,000 is over the threshold. The test is rolling: your last twelve months of taxable turnover, checked at the end of every month, not aligned to the tax year, and once you cross it you must register within the statutory window. Genuinely VAT-exempt supplies do not count towards the threshold, which is exactly why the medical exemption argument below gets so heated.
Worked example, assumptions stated: eight appointments a week at £180 across 48 weeks is £69,120, comfortably under. Add two lip filler appointments a week at £250 and you reach £93,120, and you are legally required to register. Growth you barely noticed can carry you across.
The medical exemption, honestly
Medical services are exempt from VAT only where their principal purpose is the protection, maintenance or restoration of health. That is the test, and it is applied treatment by treatment, not practitioner by practitioner. Being a nurse, doctor or pharmacist does not make your lip filler medical care; cosmetic treatments are standard-rated. HMRC actively challenges clinics claiming blanket exemption, and aesthetics VAT disputes have already reached tribunal (cases reported up to around 2022). The pattern across them is consistent: “everything we do is medical because we are medics” fails, while specific, documented, health-purpose treatments can succeed.
| Treatment | Likely VAT position | What the file needs |
|---|---|---|
| Three-area cosmetic toxin | Standard-rated | Nothing special; count it towards the threshold |
| Toxin for axillary hyperhidrosis | Potentially exempt | Diagnosis or clinical history, purpose recorded at consultation, outcome notes |
| Toxin for bruxism or migraine | Potentially exempt | The same discipline, per patient, per visit |
| Lip or cheek filler | Standard-rated | No paperwork makes this medical |

Records that survive inspection
If you do genuine medical-purpose work, the exemption is won or lost in the notes. What holds up is a contemporaneous consultation record stating the health purpose, the assessment behind it and the outcome, made at the time of treatment. What collapses is a percentage split invented at year-end, or notes rewritten once a VAT enquiry letter arrives.
Consistency matters as much as documentation. You cannot tell HMRC a treatment is medicine while treating it as cosmetic everywhere else, because toxin for hyperhidrosis, bruxism or migraine is a CQC-regulated activity in England (treatment of disease). The CQC guide covers what that means in practice; the short version is that the medical purpose helping your VAT position also changes your registration position, and inspectors of both kinds can read.
The cliff edge
Cross the threshold by a pound and VAT applies to your standard-rated sales from registration onwards. You then have two options: raise prices by 20% overnight, or hold them and hand HMRC roughly a sixth of your takings. Worked example, assumptions stated: hold prices at £100,000 of standard-rated turnover and about £16,667 of it becomes output VAT, before whatever input VAT you can recover on costs. Neither option is pleasant, which produces the tempting third one: splitting.
Legitimate separation exists. Genuinely distinct businesses, with their own premises, records, bank accounts, branding and economic reality, are treated separately. Artificial separation does not survive contact with HMRC, which has powers to direct that split businesses be treated as one; a spouse’s company running the same clinic on Tuesdays is the textbook failure. Deliberately capping growth below £90,000 is legal, and it is also a permanent ceiling on the business. The braver plan is usually to register, reprice with the cost-stack method, and grow through it. Whichever way you lean, decide with an accountant before £70,000 on the rolling test, not after a brown envelope.
Side hustles and self assessment
Most readers start in practice while employed by the NHS, and PAYE does nothing about self-employed clinic income. The basics: register for self assessment by 5 October following the end of your first trading tax year; the £1,000 trading allowance covers genuinely tiny experiments but nothing resembling a practice (HMRC, checked July 2026); and year two brings payments on account, which surprise nearly everyone by front-loading part of the next year’s bill. Product, room hire, insurance and consumables are normal business expenses. Your original foundation training is usually not deductible, while training that updates existing skills usually is, and the line between the two is exactly the sort of thing to put to an accountant rather than a forum.
Doctors in training ask us a related question: “do I have to declare it on my Form R?” That is a scope-of-practice declaration to your deanery, entirely separate from anything HMRC wants, and the safe answer is yes, declare all paid work. Tax honesty and professional honesty run on different forms, and you need both.
When to hire an accountant
Earlier than feels proportionate. Certainly when rolling turnover approaches £70,000, when you do or plan any medical-purpose work, when you are choosing between sole trader and limited company, or when HMRC writes to you, at which point the right time was last year. Choose one who already acts for clinics or medical practices; a generalist learning aesthetics VAT on your file is expensive education. Their fee belongs in the fixed costs of your start-up ledger, and it is small against a five-figure retrospective VAT assessment.
Records to keep from day one
- Monthly takings on a rolling twelve-month view that you actually look at
- A per-treatment record of purpose, cosmetic or documented medical, made at the time
- Invoices for product, room hire, insurance and training
- A separate business bank account, however small the business
- Mileage and home-clinic use notes, if either applies
- A dated threshold check every quarter, filed where you will find it

Frequently asked questions
When your taxable turnover passes £90,000 over any rolling twelve months (HMRC, checked July 2026). Turnover means takings, not profit, and the test runs at the end of every month rather than by tax year. In a worked example, around eleven appointments a week at a £180 average crosses it. Registration then becomes a legal obligation with a statutory deadline, so track the rolling figure monthly.
No. The medical exemption applies only where a treatment’s principal purpose is the protection, maintenance or restoration of health, and it is judged per treatment, not per practitioner. Cosmetic toxin and filler work is standard-rated whatever your registration. HMRC actively challenges blanket claims and aesthetics disputes have reached tribunal. Documented health-purpose work, such as hyperhidrosis or bruxism treatment, can qualify, but only with the records to prove it.
Contemporaneous consultation notes recording the health purpose, the clinical assessment behind it and the outcome, made at the time of each treatment. Percentage splits invented at year-end, or notes rewritten after an enquiry letter, collapse under scrutiny. Consistency also matters: toxin for hyperhidrosis, bruxism or migraine is a CQC-regulated activity in England, so your VAT story and your regulatory story need to match.
Only if the businesses are genuinely separate, with their own premises, records, bank accounts and economic reality. HMRC has powers to direct that artificially split businesses be treated as one, and a spouse’s company running the same clinic on different days is the textbook failure. Deliberately capping growth below £90,000 is legal but permanent; registering and repricing is often the better plan. Take advice first.
Yes. PAYE on your NHS salary does nothing about self-employed clinic income. Register for self assessment by 5 October following the end of your first trading tax year, keep records of income and expenses, and expect payments on account from year two. The £1,000 trading allowance covers only tiny experiments. Doctors in training should also declare the work to their deanery, which is a separate obligation.
