Pilates, Back Pain and the HMRC Rule That Ruins Everything

Every January, Amy does what most accountants do. She reviews the year. Expenses in, expenses out. Everything in its rightful column.

And every January, she arrives at the same question: can she claim Pilates?

The answer is no. It has always been no. It will continue to be no.

But the reasoning is worth understanding, because it applies to a lot of things people assume they can claim.

The rule: wholly and exclusively

HMRC's test for a business expense is whether it was incurred wholly and exclusively for the purposes of the trade.

Pilates keeps Amy healthy. A healthy Amy can work. Therefore, Pilates supports the business.

It's a logical chain. HMRC doesn't follow it.

The problem is that Pilates also benefits Amy as a person — not just as a business owner. The moment an expense has a personal benefit, the "wholly and exclusively" test fails.

It doesn't matter how much the activity helps you work. If it also benefits you as a human being, it's personal.

"But what about the back pain?"

Here's where it gets interesting — and where Amy spent approximately three minutes genuinely believing she'd found a loophole.

The logic goes: accountants sit at desks. Desks cause back pain. Pilates treats back pain. Therefore, Pilates is a work-related medical expense.

It's a good argument. It just isn't a winning argument.

HMRC's position on physiotherapy and medical treatment follows the same "wholly and exclusively" logic. Even when back pain is clearly caused or worsened by the nature of your work, the treatment benefits you as a person — not exclusively as a business owner.

There is one famous exception: a stuntman successfully claimed private physiotherapy after an injury because waiting for NHS treatment would have directly cost him work. The physical recovery was inseparable from his ability to do the job at all. It's a compelling case, and it set a precedent — but a narrow one. An accountant with a bad back doesn't clear the same bar.

Who actually can claim fitness costs?

The list is shorter than most people hope, but it's worth knowing.

Professional athletes and performers can make a reasonable case — their body is the product, and fitness is a professional requirement, not a lifestyle choice.

Fitness instructors are interesting. If you're a self-employed Pilates teacher and you attend Pilates classes to maintain your technique and demonstrate movements to clients, there's a legitimate argument for professional development. Your body demonstrating the practice is the service. That's a different situation to Amy's.

For everyone else — business owners, directors, consultants, freelancers whose product is their time and expertise rather than their physical capability — the answer is almost always no.

What a limited company can do

If you run a limited company, there are a couple of things worth knowing.

Directors can receive one annual medical check-up per year, paid for by the company, as a tax-free benefit. Not ongoing treatment, not classes — but if you haven't had yours, it's worth arranging.

And if you employ a team: recent HMRC guidance has broadened the rules around workplace counselling and mental health support. If a wellbeing benefit is available to all employees — not just the directors — it may be deductible.

The verdict

Amy pays for Pilates herself. She has always paid for Pilates herself. She will continue to pay for Pilates herself. She's made her peace with it.

What she does make sure of is that everything she legitimately can claim, she claims. Home office costs, equipment, professional subscriptions, professional development, travel, her annual health check. The savings are real — they just don't show up on a Pilates invoice.

If you're not sure you're claiming everything you're entitled to, that's what we're here for. No judgment. No spreadsheet anxiety. Just a straight answer.
