If you’re a doctor in the UK doing private work, locum shifts, or running your own practice, one question eventually comes up. Many people want to understand which one is better, a sole trader vs limited company for doctor UK. Honestly, there’s no single answer that works for everyone. But there are definitely some clear patterns! Most doctors earning under £50,000 from private work are fine as a sole trader. And once your income grows, a limited company can often be more tax-efficient. In this sole trader vs limited company doctor UK guide, we will help you make the decision between sole trader vs limited company for doctor UK. What Does It Actually Mean to Trade as a Sole Trader? Being a sole trader is the simplest way to start working for yourself. You and the business are legally the same thing. If you earn £1,000 from a private clinic, that money belongs to you immediately. You must report this income to HMRC through Self Assessment. In the sole trader vs limited company for doctor UK comparision, operating as a sole trader is generally simpler. But you are also personally liable for everything. Your profits are taxed as personal income. So if your private work earns you £60,000 profit, you pay income tax and National Insurance on that £60,000, at whatever rate applies to you. For 2026/27, the income tax bands in England are: Income Tax Rate Up to £12,570 0% (Personal Allowance) £12,571 – £50,270 20% (Basic Rate) £50,271 – £125,140 40% (Higher Rate) Over £125,140 45% (Additional Rate) On top of income tax, you also pay Class 4 National Insurance. It is 6% on profits between £12,570 and £50,270, then 2% above that. Class 2 is generally no longer required. However, voluntary payments can be made to fill gaps in state pension records. Important: if your income goes above £100,000, your personal allowance starts being withdrawn. £1 for every £2 you earn above that threshold. And by £125,140, it’s gone entirely. This creates what’s effectively a 60% marginal tax rate in that band. Pension contributions are one of the most reliable ways to bring income back below that £100,000 line. Is a Sole Trader Structure Simple to Run? Yes. It is much simpler than a limited company. There’s no Companies House filing requirement, no corporation tax return, no director’s duties. You just track your income and deductible expenses. Then you have to tell HMRC about your earnings. If your qualifying income is over £50,000, you are now required to use Making Tax Digital (MTD) compatible software to send quarterly updates to HMRC. Many medical professionals find that the choice of sole trader vs limited company for doctors in the UK comes down to this desire for reduced administration. What About a Limited Company for Doctors? A limited company is a separate legal entity. It pays corporation tax on its profits, not income tax like sole traders. You, as a director, then pay yourself through a mix of salary and dividends. When analysing sole trader vs limited company for doctor UK, you’ll see that this combination is usually more tax-efficient than taking everything as personal income. For 2026/27, corporation tax rates are: Company Profit Corporation Tax Rate Up to £50,000 19% (Small Profits Rate) £50,001 – £250,000 Marginal Relief applies Over £250,000 25% (Main Rate) Most private practice doctors fall in that first band. So they’re paying 19% corporation tax on profits inside the company. Then, when you extract money, you’d typically pay yourself a salary up to around £12,570 (no income tax, minimal National Insurance) and top up with dividends. Dividends are taxed at lower rates than salaries. And importantly, they don’t attract National Insurance. Dividend Tax Rates for 2026/27 This is where it’s changed. From April 2026, dividend tax rates increased. This is a crucial update for anyone comparing a sole trader vs limited company for doctor UK: Dividend Received Tax Rate Up to £500 (allowance) 0% Basic rate taxpayer 10.75% Higher-rate taxpayer 35.75% Additional rate taxpayer 39.35% The dividend allowance is £500 for the 2026/27 tax year. It has significantly dropped from the £2,000 allowance seen just a few years ago. Consequently, the tax-saving gap in the sole trader vs limited company for doctors UK has narrowed compared to a few years ago. However, for higher earners, there can still be a meaningful tax advantage.

As a sole trader doing NHS locum work through PAYE, you can continue contributing to the NHS Pension Scheme. When evaluating the choice of a sole trader vs limited company for doctors in the UK, many consultants and GPs find that this defined benefit pension is worth far more than almost any private alternative. If you route your NHS locum or private income through a limited company, that income is not pensionable under the NHS Pension Scheme. You’d need to set up a private pension instead. When reviewing the benefits of a sole trader vs limited company for doctors in the UK, this loss of pensionable pay is often the biggest deterrent for the corporate route. You can still make pension contributions through a limited company. That’s up to the annual allowance of £60,000 for 2026/27. These contributions are corporation tax-deductible and can be highly tax-efficient. But it’s not the same as the NHS Pension, and for many doctors it’s not a fair swap. If your NHS Pension is already healthy and you’re building up significant private practice income separately, a limited company for that private work can work well. But if you’d be sacrificing …
