Being a self-employed personal trainer or fitness professional is an incredibly rewarding career. Often, no two weeks will look the same! Not only are you delivering high-quality training sessions and personalised coaching, but you also have to make time to manage client bookings, programme workouts, maintain your equipment, market your services, the list goes on. As for working early mornings, evenings, and weekends, it’s all part and parcel of the job.
Whether you’re training clients in a gym, offering mobile sessions, or running your own fitness studio, there’s always something demanding your attention. And in the middle of such a chaotic schedule, it’s easy for things like accounting and tax responsibilities to slip down the priority list.
If you work in the fitness industry, getting ahead with your annual Self-Assessment Tax Return now could save you a lot of future headaches as the deadline approaches. Want to find out how we can help? Just keep reading…
Benefits of an accountant
With everything you have on your plate, the last thing you need is the added pressure of figuring out your taxes. In fact, for a lot of self-employed people, taxes are one of the main downsides of the job! Look, we get it; crunching numbers can be tedious. This is where an accountant can be a game-changer.
A qualified accountant takes the stress off your shoulders by handling your finances professionally and efficiently. They make sense of all the numbers, ensure your tax return is accurate, and keep you compliant with HMRC. Instead of losing evenings to paperwork or worrying about making a mistake, you get peace of mind and a lot more time to focus on growing your business and serving your clients. With your energy redirected to other responsibilities, you can trust that you’ll get through your workload quicker. Plus, no need to keep on top of changing tax laws and legislation if somebody else is doing that for you.
Tax responsibilities for fitness & PT professionals
You probably already know by now that as a self-employed professional in the UK, you’re responsible for submitting a Self-Assessment Tax Return (more below) every year which includes a breakdown of your income and expenses for the previous tax year. HMRC won’t send you any reminders – it’s up to you to mark your calendar and keep track of approaching deadlines. Here’s a quick breakdown of key tasks:
- Gathering all income records (from clients, online payments, or product sales)
- Collecting receipts for allowable business expenses
- Calculating your total income, deducting expenses, and working out your profit
- Submitting your tax return via HMRC’s online portal
Keys dates:
5th October: deadline to register as self-employed and register for self-assessment. This is only for the self-employed newbies in their first year.
31st January: deadline to file your online tax return and pay any tax owed for the previous tax year.
31st July: second payment on account due. This is only for some self-employed individuals, so make sure to check whether or not it applies to you.
Missing these deadlines can result in late filing penalties and interest charges.
What is a Self-Assessment Tax Return?
A Self-Assessment Tax Return (SATR) is how you report your income to HMRC. If you’re self-employed (normally when you’re earning income outside PAYE employment) or have multiple income streams, this applies to you. It covers all taxable earnings within the financial year which runs from 6th April to 5th April. When you submit your return, you’re essentially informing HMRC of how much you earned, how much tax and National Insurance you owe, and what your business expenses were.
When it comes to expenses, there’s a lot you can claim…
Business expenses: claiming for supplies
What are allowable business expenses? We’ve used an example below to demonstrate how it works.
Let’s say you’re a self-employed personal trainer hiring space in a local gym or running sessions in parks and clients’ homes. You pay for your own equipment, branded kit, insurance, fitness apps, and social media ads. You might also be covering gym rent or fuel costs if you’re travelling between sessions. These are all genuine business expenses, which means they can reduce how much tax you owe.
But the reality is, lots of fitness professionals miss out on claiming what they’re entitled to. Either they’re unsure what counts as an allowable expense, or they’re nervous about getting it wrong and facing HMRC penalties. If you fail to claim allowable expenses, you could end up overpaying on your taxes. That’s why working with an accountant who understands the fitness industry and the complexities of tax can really pay off. They’ll make sure:
- Gym rental or space hire is properly logged as a regular business cost
- Kit and equipment are classed under tools and essentials
- Courses and workshops are claimed as professional development
- Travel and mileage for client sessions are recorded accurately
This attention to detail can make a huge difference when it comes to your final tax bill. Minimising your tax liability in legal ways is exactly what a professional accountant can do for you, so you can rest assured you’re claiming for everything you can and nothing you can’t.
