Deciding to work for yourself in the UK healthcare sector is a huge step. And the most common way to start is to register as a sole trader. It is simple, cost-effective, and gives you full control. However, the rules around tax and digital reporting are changing, especially with the 2026 updates from HMRC. In this guide, we will walk you through exactly how to register as a sole trader.

Instead of being paid only through PAYE, you manage your income, expenses, and annual Self Assessment tax return yourself. Many healthcare professionals prefer this structure because: It is quick to start You keep full control of your income Costs are usually lower in the early stages There is less admin compared to a limited company You and your business are legally the same entity, which means profits belong to you personally. You pay Income Tax on these profits if they exceed your Personal Allowance (which is £12,570 for most people but reduces if you earn over £100,000). You also pay Class 4 National Insurance at a rate of 6% on profits between £12,570 and £50,270 (and 2% on anything above that). Compulsory Class 2 National Insurance has been abolished for most; if your profits are above £6,845, you are ‘deemed’ to have paid it. However, you may still choose to pay it voluntarily if your profits are below that level to protect your State Pension. Who Needs To Register as a Sole Trader? You normally need to register as a sole trader if you earn more than £1,000 in a tax year from self-employed work. This applies to many healthcare roles, including: Locum doctors or nurses working independently Private physiotherapists or therapists Healthcare consultants Freelance medical writers Dental professionals working privately Allied health professionals offering services outside employment Even if you still work for the NHS or a clinic, you must register as a sole trader if you start earning extra income on the side. When Should You Register as a Sole Trader? You do not need to register immediately after your first payment, but HMRC has a deadline. You must register by 5 October following the end of the tax year in which you started trading. Example: If you start earning in June 2025, the tax year ends on 5 April 2026. Your registration deadline would be 5 October 2026. Registering early avoids last-minute pressure and gives you more time to plan your taxes properly. How To Register as a Sole Trader With HMRC The actual process of telling HMRC you are starting out is done through a system called Self Assessment. Most people do this online because it is the quickest way to get your Unique Taxpayer Reference (UTR). Set up your Government Gateway user ID If you have ever checked your personal tax account or renewed a driving licence online, you might already have one. If not, you’ll need to create one using your email address and some ID like your passport or P60. Register for Self Assessment Once you are logged in, you tell HMRC that you are starting as a sole trader. They will ask for: Your full name and address. Your National Insurance number. The date you started your healthcare business. The type of work you do (e.g., “Private Nursing Services”). Wait for your UTR number After you register, HMRC will send you a Unique Taxpayer Reference (UTR) in the post. This is a 10-digit number that stays with you for life. Keep it safe because you cannot file a tax return without it. What Information Do You Need To Register? Before you register as a sole trader, gather these details: National Insurance (NI) number Personal contact details Business start date Description of your healthcare work Business address Expected income details Important Deadlines You Cannot Miss HMRC is strict about dates. If you started working for yourself between 6 April 2025 and 5 April 2026, you must register as a sole trader by 5 October 2026. Action Deadline Registering for Self Assessment 5 October 2026 Filing a paper tax return 31 October 2026 Filing an online tax return 31 January 2027 Paying your final tax bill 31 January 2027 Note: From 6 April 2026, you must use MTD if your qualifying income was over £50,000 in the 2024/25 tax year. For those starting in 2025/26, you will likely be mandated from April 2027 if your income exceeds £30,000. Do Healthcare Workers Need Extra Registration? Unlike a plumber or a graphic designer, a healthcare professional often needs to register with a regulator beyond just HMRC. Before you register as a sole trader, you must check if your work involves “regulated activities” (like medical treatments or personal care). In England, you may need to register with the Care Quality Commission (CQC). However, specific rules apply: Doctors: Individual GMC-registered doctors working as sole practitioners are often exempt if they see patients only in a physical surgery. However, you must register if you provide remote care (video/phone), surgical procedures, or diagnostic tests. Dentists: This exemption does not apply to dentists. You must always register with the CQC to provide private dental care. Nurses: For nurses, the rules are even stricter. There is no “sole practitioner” exemption for nursing, so if you provide clinical treatment independently, you must register with the CQC. If you are based in Wales, you may need to register with Healthcare Inspectorate Wales (HIW). In Wales, almost all private dental practices and independent clinics must register. If a doctor or dentist works from a fixed location that isn’t an NHS hospital, it is usually classed as an …
