An accountant for athletes does a different job from a high-street accountant. An athlete’s income arrives in a shape the tax system was not built for. A boxer might earn more in one fight than in the previous three years combined, then earn nothing for eight months. The tax rules do not care. This guide explains how UK athletes are taxed, where the money goes wrong, and what an accountant for athletes should be doing about it.
What does an accountant for athletes actually do?
An accountant for athletes manages the tax, cash flow and structure around a career that is short, lumpy and often international. The core work is Self Assessment and payments on account. It includes deciding whether a limited company or image rights company makes sense, claiming the right expenses, and dealing with income earned abroad. Above all it means keeping enough cash aside so a January tax bill never arrives as a surprise. For clubs, gyms and promoters the work shifts to payroll, VAT and management accounts. The principle is the same: the numbers have to be right before the season, not after it.
What an accountant does not do is pick investments or tell you what to do with your money. That is regulated financial planning, and it needs an FCA-authorised adviser. We are both. That is why the tax position and the plan get built together, rather than by two firms arguing afterwards.
How are professional athletes taxed in the UK?
Most professional athletes outside a club payroll count as self-employed sole traders under Self Assessment. That covers boxers, fighters, golfers and tennis players. It covers anyone whose income comes from purses, prize money, sponsorship and endorsements rather than a salary. They pay 20% income tax on taxable income between £12,571 and £50,270, then 40% between £50,271 and £125,140, and 45% above that. Income over £125,140 loses the £12,570 personal allowance entirely. Class 4 National Insurance applies on top.
A footballer or rugby player on a club payroll pays tax through PAYE like any employee. But almost all of them also have self-employed income from image rights, boot deals and appearances. That brings them into Self Assessment as well. Very few professional athletes have a simple tax position, which is why a general accountant for athletes is rarely enough.
Why does the first big year cause a tax bill of 150%?
The first big year causes a bill of roughly 150% of a year’s tax because Self Assessment demands the tax owed plus half of next year’s estimated tax on the same day. Once your bill exceeds £1,000, HMRC requires payments on account. These are two instalments, each half of last year’s tax, due by 31 January and 31 July. In the first year you make them, 31 January brings the full bill for the year just ended plus the first instalment for the year you are in.
Take a fighter whose income jumps and whose tax bill comes to £40,000. On 31 January they owe that £40,000 plus a £20,000 payment on account. That is £60,000 in one day, with another £20,000 due on 31 July. If the purse has already gone on a car and a deposit, the career starts getting taxed twice: once by HMRC, and once by the interest and penalties for paying late.
If you know the following year will be quieter, you can apply to reduce the payments on account. Reduce them too far and HMRC charges interest on the shortfall. This is the single most common problem an accountant for athletes sees in new clients. It is entirely avoidable if someone is setting money aside from every purse.
Why are short careers a tax problem?
Short careers are a tax problem because the UK taxes income year by year and gives sportspeople no way to spread it. A career that earns £1.5 million over eight years pays far more tax than one earning the same £1.5 million over thirty. More of it lands in the 40% and 45% bands, and the personal allowance disappears in the peak years. Farmers and authors have an averaging relief to smooth good years against bad ones. Athletes do not, which is why an accountant for athletes has to plan around the peaks rather than tidy up after them.
That leaves timing and structure as the only levers. When is income invoiced? When are expenses incurred? Should a company hold part of the income? What happens to peak-year profits before the year ends? Pension contributions are one of the few ways to move income out of a peak year. Whether and how much is regulated financial advice and depends on your circumstances. It is a conversation to have with an FCA-authorised adviser before the tax year ends, not after.
What is an image rights company and does it work?
An image rights company is a limited company that owns the commercial rights to an athlete’s name, likeness and reputation, and licenses them to sponsors, clubs and brands. The company pays corporation tax on that licence income at 19% on profits up to £50,000 and 25% above £250,000, with marginal relief between, against a personal rate of up to 45%. Money is then drawn out as salary or dividends, or left in the company.
It works when the image has real, provable commercial value that a third party would pay for. HMRC has spent years challenging arrangements that fail that test. A club paying a player’s company for “image rights” that are really disguised wages is one example. A young athlete with no sponsorship history routing personal income through a company is another. For a fighter with genuine endorsement and media income, it can be the right structure. For most athletes early in their careers, it is a cost and a compliance burden that does not yet pay for itself. The question is not “should I have one”. It is “what would a brand actually pay to use my name today”.
What expenses can a professional athlete claim?
A professional athlete can claim any expense incurred wholly and exclusively for the purpose of earning their sporting income. In practice that means:
- Trainer, coach, manager and agent fees, including percentage cuts taken from a purse before you see it. If your promoter pays your trainer directly out of your purse, that cut is still your expense. You only get the deduction if you record it.
- Gym membership, training camp costs, sparring partners, cornermen and cutmen.
- Physiotherapy, sports massage, medical checks and licence fees required to compete.
- Kit, equipment and supplements used in training and competition.
- Travel and accommodation to camps, fights and events, including the cost of taking your team with you.
- Accountancy, legal and professional fees.
You cannot claim anything with a dual purpose: ordinary food, everyday clothing, or a car used personally as well as for training. The biggest failing we see is not over-claiming but under-claiming. Nobody documented the purse deductions, and camp costs went out in cash. A record of every payment out, kept at the time, is worth thousands a year. Setting that system up is the first job any accountant for athletes should do.
What happens when an athlete earns money abroad?
A UK-resident athlete who earns abroad pays UK tax on that income, and usually loses a slice to tax at source in the country where they competed. Most countries take a slice of prize money, appearance fees and purses paid to visiting sportspeople before the money leaves. The UK then taxes the same income again, but allows credit for the foreign tax paid. You only get that credit if you can document the foreign tax. So the withholding certificate from a fight in Las Vegas or Riyadh matters as much as the purse.
It works in reverse too. HMRC taxes non-resident sportspeople on income connected with UK performances, with tax deducted at source by the payer. That includes a share of worldwide endorsement income apportioned to the days spent competing here. Overseas fighters coming to the UK, and UK fighters relocating abroad, both need to plan this before signing the contract. An accountant for athletes should be in the room at that point, not after the money has moved.
Should an athlete trade through a limited company?
An athlete should trade through a limited company only when the tax saving outweighs the extra cost and complexity. That usually means sustained profits well above the higher-rate threshold and a genuine reason to leave money in the company. A sole trader pays income tax on everything they earn in the year, whether they spend it or not. A company pays corporation tax at 19% to 25%, and the owner pays personal tax only on what they draw out. Profits that stay in the company to fund the quiet years, or the years after retirement, carry a lighter charge at first.
Against that, a company means statutory accounts, a corporation tax return, payroll for any salary, dividend paperwork and Companies House filings. For an athlete earning £40,000 a year, the company rarely pays for itself. For one earning £400,000 with several years left, it usually does. It is a calculation, not a rule of thumb. Run it on your actual numbers.
What do gyms, clubs and promoters need from an accountant?
Gyms, clubs and promoters need an accountant who handles payroll, VAT and cash flow around a season rather than a steady twelve months. Three points catch sports businesses out more than any others. First, VAT registration is compulsory once taxable turnover in the last twelve months passes £90,000, and sponsorship income counts. A sponsor who receives advertising or hospitality in return is buying a service, not making a donation. Second, coaches and staff paid as self-employed are often employees in HMRC’s eyes. The employer carries the liability when that is reassessed. Third, gate and event income lands in a few weeks of the year while wages and rent run across all fifty-two. A cash flow forecast is not a luxury.
Does Making Tax Digital apply to athletes?
Making Tax Digital for Income Tax applies to self-employed athletes once their qualifying income passes the threshold, and the first group are already in it. Sole traders with self-employment and property income over £50,000 in 2024/25 had to start from 6 April 2026. Those over £30,000 in 2025/26 join from 6 April 2027. Those over £20,000 in 2026/27 join from 6 April 2028. It means keeping digital records and sending HMRC quarterly updates through compatible software, on top of the annual return. For an athlete whose income arrives in two or three large payments a year, the quarterly rhythm is a change of habit. The penalties for missing it are automatic.
What should you look for in an accountant for athletes?
An accountant for athletes should have dealt with purse income, image rights and overseas withholding before, and should be a chartered firm regulated by a professional body. They should tell you what to set aside from each payment, rather than what the bill was afterwards. Ask how many sportspeople they act for. Find out whether they can give regulated financial planning advice or will need to refer you elsewhere. Then ask what happens in the years when injury stops you earning. The answers tell you whether they understand the shape of your career, or are treating you like a plumber with a good year.
Frequently asked questions
Are professional boxers self-employed?
Yes. Professional boxers in the UK are almost always self-employed. They pay tax through Self Assessment on purses, sponsorship and appearance income, and make payments on account each 31 January and 31 July once their bill exceeds £1,000.
Is prize money taxable in the UK?
Prize money earned by a professional athlete is taxable as trading income in the UK. Prizes won by a genuine amateur with no trade are generally not taxable. The line between amateur and professional is about the pattern of activity, not the label.
How much should an athlete put aside for tax?
An athlete should put aside a proportion of every payment based on their expected marginal rate. For anyone earning into the higher-rate band, that usually means setting aside 40% or more of each purse after deductible costs, before spending anything. The exact figure depends on total income and expenses, so calculate it rather than guess.
Can an athlete’s agent fees be claimed against tax?
Yes. Agent and manager fees incurred to earn sporting income are deductible expenses for a self-employed athlete. That includes percentages a promoter takes out of a purse before payment, provided you document them.
