The Medical Professional's Tax Situation Is Not Standard

If you are a GP, hospital consultant, dentist, or other medical professional working in the UK, your tax affairs are more complex than the average business owner. You might hold multiple contracts simultaneously: an NHS salaried role, a locum position through a limited company, and private practice income. Each income stream is taxed differently.

A standard high street accountant can file your self assessment return. But can they optimise your NHS pension annual allowance position? Can they structure your locum work to avoid an IR35 hit while staying compliant? Can they advise on the VAT implications of private practice when your turnover crosses the threshold? In most cases, the answer is no.

That is why an accountant for medical professionals is not a luxury. It is a financial necessity for anyone earning above the basic rate threshold or holding multiple income sources.

Why Medical Professionals Need Specialist Accountancy Support

The tax rules that apply to doctors, dentists, and other healthcare professionals are not the same rules that apply to a plumber or a freelance graphic designer. Three specific areas make the difference significant.

NHS Pension Annual Allowance

The NHS Pension Scheme is one of the most generous defined benefit schemes in the UK. But it also creates one of the most complex tax problems for senior clinicians. The annual allowance for pension contributions is £60,000 for 2025/26. However, because the NHS Pension is a defined benefit scheme, the "value" of your pension growth is calculated using a 16-times multiplier on your increased annual pension. If you get a pay rise or work extra sessions, your pension growth can far exceed £60,000 without you seeing a penny of actual cash.

This triggers an annual allowance tax charge. You pay income tax on the notional growth at your marginal rate. Many consultants and GPs receive tax bills of £10,000, £20,000, or more purely from pension growth. A standard accountant who does not understand NHS pensions will miss this entirely. They will file your return without the scheme pays election, leaving you to pay a cash tax bill on growth you cannot access.

A specialist accountant for medical professionals will calculate your pension input amounts, advise on scheme pays elections, and help you plan your sessions to stay within allowances where practical.

IR35 and Locum Work

If you work as a locum GP or hospital doctor through your own limited company, IR35 is the single biggest threat to your take-home pay. Since April 2017, the public sector IR35 rules have applied to most NHS engagements. NHS trusts and health boards are responsible for determining your status. In practice, many default to "inside IR35" for standard locum shifts, meaning you pay tax and NI as if you were an employee.

But the position is not uniform. Some locum roles, particularly out-of-hours work or independent contractor arrangements with private hospitals, fall outside IR35. The difference is substantial. Inside IR35, you might take home 55-60% of your gross income after tax, employer NI, and umbrella fees. Outside IR35, with proper planning, you can retain 70-75% or more through dividend-based remuneration.

Your accountant needs to know the specific HMRC tests for medical professionals. They need to understand the role of substitution clauses, control, and mutuality of obligation in a clinical setting. A generic accountant may not know the difference between a standard GP locum and a freelance consultant surgeon operating under a service agreement.

Private Practice Structure

If you see private patients alongside NHS work, you have choices about how you structure that income. You can operate as a sole trader, through a partnership, or through a limited company. Each option has different tax implications, pension implications, and liability considerations.

Many private consultants use a limited company for their private practice income. This allows them to retain profits within the company at 19% or 25% corporation tax, rather than paying 40% or 45% income tax immediately. But the structure must be commercially real. If HMRC challenges it under the IR35 rules or the settlements legislation, you could face significant back taxes and penalties.

A specialist accountant for medical professionals will help you choose the right structure for your specific mix of NHS and private work, your pension position, and your long-term plans.

What to Look for in an Accountant for Medical Professionals

Not every accountant who says they work with doctors actually understands the detail. Here are the specific capabilities you should expect.

  • NHS pension knowledge. They should be able to calculate your annual allowance position, advise on scheme pays, and help with the pension savings statements issued by NHS England or NHS Scotland.
  • IR35 expertise. They should know the difference between inside and outside IR35 determinations for locum roles and be able to advise on contract reviews and status determinations.
  • Private practice structuring. They should be able to model the tax outcome of sole trader, partnership, and limited company structures for your specific income levels.
  • VAT awareness. If your private practice turnover exceeds £90,000 in any rolling 12-month period, you must register for VAT. A specialist will help you decide whether to use the Flat Rate Scheme and how to handle the interaction with NHS income.
  • Child benefit and high income child benefit charge. Many medical professionals earn above £60,000, triggering the High Income Child Benefit Charge (HICBC). Your accountant should factor this into your overall tax planning.
  • Student loan repayments. Plan 2 and Plan 5 student loan repayments at 9% above £27,295 (Plan 2) or £25,000 (Plan 5) can be a significant cost for younger clinicians. Good planning minimises the impact.

Common Tax Mistakes Medical Professionals Make

We see the same errors repeatedly when new clients come to us after outgrowing their previous accountant.

Not claiming allowable expenses. Medical professionals can claim a wide range of expenses that many miss. GMC registration fees, indemnity insurance, medical defence union subscriptions, professional memberships (BMA, BDA, RCGP, RCS), specialist clothing (scrubs, white coats), and travel between workplaces (not home to work) are all allowable. A specialist will know the full list and ensure nothing is missed.

Mixing NHS and private income in one company. Some consultants try to put all their income through a single limited company. This creates IR35 problems for the NHS element and can trigger HMRC enquiries. The better approach is usually to keep NHS salary separate and use a company only for private practice income.

Ignoring the pension annual allowance. As discussed above, this is the single biggest tax trap for senior clinicians. We regularly see consultants who have accrued six-figure annual allowance tax charges without realising it. By the time they find out, the interest and penalties are substantial.

Choosing the wrong partnership structure. If you are in a GP partnership or a dental partnership, the partnership agreement and profit-sharing arrangements have direct tax consequences. A specialist accountant will review your partnership deed and advise on the most tax-efficient profit allocation.

Real Example: A Consultant in Manchester

Take a consultant anaesthetist working in Manchester. She holds an NHS salaried role paying £95,000. She does private anaesthetic work through her limited company, turning over £65,000. She also does occasional locum shifts at a private hospital, paid gross via an umbrella company.

A standard accountant would file her self assessment, claim her GMC and indemnity fees, and leave it at that. But her NHS pension growth, combined with her private company profits, pushes her annual allowance well over £60,000. She faces an annual allowance tax charge of roughly £14,000. Her accountant never mentioned scheme pays. She paid the tax out of her post-tax income.

With a specialist accountant for medical professionals, the approach changes. We calculate her pension input amounts using her NHS pension savings statements. We elect for scheme pays, meaning the NHS Pension Scheme pays the tax charge in exchange for a reduction in her future pension. We restructure her private company to pay her a salary at the personal allowance threshold and dividends up to the basic rate band. We review her locum contracts to confirm they are outside IR35 and advise on the appropriate contract terms to maintain that position.

The result: she saves approximately £8,500 in the first year and avoids a recurring annual allowance cash flow problem.

When Should You Switch to a Specialist Accountant?

If any of the following apply to you, it is time to consider a change.

  • Your total income (NHS salary plus private/locum) exceeds £80,000.
  • You hold a GP partnership or dental partnership interest.
  • You operate a limited company for locum or private practice income.
  • You have received an annual allowance tax charge or a pension savings statement showing growth above £60,000.
  • HMRC has opened an enquiry into your tax return.
  • You are considering incorporating your private practice for the first time.

Final Thoughts

The difference between a standard accountant and a specialist accountant for medical professionals is not small. It is the difference between paying more tax than you need to and keeping more of what you earn. It is the difference between a surprise tax bill for pension growth and a planned, manageable position. It is the difference between a generic self assessment and a comprehensive financial strategy.

If your income is above the basic rate threshold, if you hold multiple contracts, or if you have any private practice income, do not leave your tax planning to a generalist. Invest in a specialist. The return on that investment will far exceed the fee.
