Knowing exactly what medical professionals can claim against tax is one of the simplest ways UK doctors reduce a tax bill legally. Whether you are a GP partner, a salaried GP, a hospital consultant or a locum, the principle is the same: an expense is allowable only where it is incurred wholly and exclusively for your profession (ITTOIA 2005 s.34 for the self-employed, or the stricter employment test for the employed). It must be necessary for your work and not something you would have paid for personally.

This is the broad overview of claimable expenses for all UK doctors. If you want a role-specific deep dive, we link out below to our GP tax deductions list and our locum doctor expenses guide rather than repeating them here.

Professional Registration, Indemnity and Membership Fees

These are usually the most straightforward deductions, and most of them sit on HMRC's approved List 3 (the published list of professional bodies whose fees are tax-deductible):

  • GMC retention fee - the annual fee you pay to keep your licence to practise. The GMC is on List 3, so the retention fee is deductible. Restoration fees and any penalty fees are not.
  • Royal College membership - annual subscriptions to the RCGP, RCP, RCS or other specialist colleges on List 3.
  • BMA membership - the BMA subscription is allowable where it appears on List 3.
  • Faculty memberships - such as the Faculty of Occupational Medicine or the Faculty of Public Health.

For GP partners these go into the practice accounts. Salaried GPs, consultants and locums claim them individually through self-assessment.

Medical Indemnity (and the CNSGP Point Every NHS GP Should Know)

Subscriptions to a medical defence organisation are deductible:

  • MDU, MPS or MDDUS subscriptions - core membership and discretionary indemnity.
  • Additional indemnity cover - top-up cover for private practice, aesthetics or higher-risk work.

The medical-specific nuance that catches many doctors out: since 1 April 2019, NHS general-practice clinical negligence in England has been covered by the state-backed Clinical Negligence Scheme for General Practice (CNSGP) at no subscription. So an NHS GP's own paid indemnity is now mainly for private or non-NHS clinical work and for non-clinical or regulatory matters (for example a GMC fitness-to-practise investigation, complaints handling or coroner's inquests). You do not need to personally insure NHS clinical negligence, but the cover CNSGP does not reach is still worth holding, and the premium for it remains deductible. Hospital doctors are similarly covered for NHS clinical work under NHS indemnity, with their own MDO subscription covering private work and regulatory matters.

Continuing Professional Development (CPD)

CPD is claimable when it maintains or updates the skills required for your current role:

  • Course and conference fees - appraisal-relevant update courses and specialist training.
  • Travel to training - mileage (see the 55p rate below), rail fares and accommodation for genuine educational events.
  • Medical journals - subscriptions to the BMJ, the Lancet and specialty publications.
  • Online learning - e-learning subscriptions and medical education platforms.
  • Examination fees - examinations needed to maintain or progress within your current specialty.

Training that qualifies you for an entirely new specialty or a different profession is generally treated as capital in nature rather than a revenue expense, so it is usually not deductible.

Professional Equipment and Instruments

Equipment bought for professional use is allowable, but how you claim it depends on what it is:

  • Stethoscopes and clinical instruments - diagnostic equipment for practice.
  • Uniforms and protective clothing - scrubs, white coats and specialist footwear (ordinary clothing is not allowable).
  • Computer equipment - laptops, tablets and professional software.
  • Reference books - medical textbooks and clinical guidelines.
  • Medical bags - cases and home-visit kit.

Capital items (equipment with a lasting benefit, such as a laptop or a clinical machine) are usually claimed through capital allowances rather than as a day-to-day expense, but the Annual Investment Allowance gives 100% relief on up to £1,000,000 of qualifying plant and machinery a year, so in practice most doctors get full relief in the year of purchase anyway. Items used partly for private purposes must be apportioned to the business-use percentage. There is no fixed pounds-and-pence cut-off that turns a small purchase into a capital item, so consumables and low-value kit are normally just claimed as expenses.

Travel, Mileage and Subsistence

Business travel is allowable when the journey is for genuine professional purposes:

  • Between work sites - travel between different NHS sites, surgeries or clinics in a single working pattern.
  • Home visits - patient visits during the working day.
  • Locum assignments - travel to a temporary workplace.
  • Conference and CPD attendance - travel, accommodation and subsistence for genuine professional events.

If you use your own car, you can claim HMRC's approved mileage allowance: 55p per business mile for the first 10,000 miles in 2026/27, then 25p per mile (the 55p rate rose from 45p on 6 April 2026). Ordinary commuting between home and a permanent workplace is not claimable. Travel to a temporary workplace (broadly one expected to last under 24 months) does qualify, which is why a peripatetic locum can often claim a large share of their motoring. Keep a contemporaneous mileage log with the date, destination and purpose of each journey.

Home Office and Private-Rooms Costs

For doctors who work from home or run private consulting rooms:

  • Home office costs - a proportion of household running costs where you genuinely work from home.
  • Telephone and internet - the business proportion of your line and broadband.
  • Stationery and printing - professional correspondence and documentation.
  • Private-rooms rent and utilities - for private consulting space.
  • Cleaning and maintenance - upkeep of professional premises.

There are two ways to claim use of home: HMRC's simplified flat rate (a fixed monthly amount based on hours worked) or the actual-cost method apportioned by business use. Our guide to home office expenses for doctors walks through the current flat-rate bands and how to apportion actual costs, so we will not duplicate the detail here.

What Is Not Claimable

Understanding excluded expenses helps avoid compliance issues:

  • Personal medical expenses - Your own healthcare costs
  • Regular commuting - Home to permanent workplace travel
  • Personal clothing - Ordinary clothes worn at work
  • Entertaining costs - Social activities and client entertainment
  • Fines and penalties - Parking fines or regulatory penalties
  • Personal insurance - Life insurance or personal health cover

Capital expenditure that creates a lasting benefit (for example buying practice premises) is dealt with through capital allowances or the CGT rules rather than an immediate expense deduction.

How Different Medical Roles Claim

The expenses themselves are broadly the same across roles; the route to claiming them is what changes:

GP Partners

Professional costs go into the partnership accounts and reduce the practice profit before it is shared out. The partnership files an SA800, and each partner's profit share flows to the partnership pages (SA104) of their personal return. Remember a partner is taxed on their profit share, not their drawings, so relief comes through at your marginal rate via that profit figure.

Salaried GPs and Consultants

You are an employee taxed under PAYE, so you claim allowable employment expenses (List 3 subscriptions are the main one) through the employment pages of self-assessment. The employment test is stricter than the self-employed one, so genuinely necessary professional costs are the safe claims.

Locum Doctors

A sole-trader locum claims everything on the self-employment pages (SA103); see our detailed locum doctor expenses guide for the full list. If you work through a limited company, the company claims them against corporation tax. Note that a company is a private-work-only structure for doctors: it cannot hold an NHS GMS or PMS contract, and any income or dividends taken through it are not NHS-pensionable, so weigh any tax saving against the pension accrual you give up (our GP limited company guide models both sides).

Record Keeping and Making Tax Digital

Good records turn an allowable expense into a claim that survives an enquiry:

  • Keep receipts - retain the underlying evidence for each cost.
  • Document the business purpose - a short note on why each expense was necessary for your work.
  • Maintain a mileage log - date, destination and purpose of every professional journey.
  • Separate personal and professional - especially for phones, cars and home costs that are apportioned.
  • Summarise by category - organise costs ready for the return.

From 6 April 2026, Making Tax Digital for Income Tax applies to sole traders and landlords with qualifying income over £50,000 (falling to £30,000 from April 2027 and £20,000 from April 2028), bringing in quarterly digital updates and digital record-keeping. Most full-time locums and unincorporated private GPs are caught from April 2026, so the days of a shoebox of receipts are over. Limited companies are outside MTD for Income Tax, and general partnerships are deferred with no confirmed start date. HMRC normally has four years from the end of the tax year to open an enquiry (longer where there is carelessness or deliberate error), so keep records for at least that long.

Self-Assessment and National Insurance for Self-Employed Doctors

If you are self-employed (a GP partner or a sole-trader locum), your allowable expenses reduce the profit on which you pay both income tax and Class 4 National Insurance. For 2025/26 Class 4 is 6% on profits between £12,570 and £50,270, then 2% above that. Class 2 National Insurance is no longer a required weekly payment from 6 April 2024: if your profits are at or above the small-profits threshold you are treated as having paid it and keep your state-pension entitlement, so do not let anyone tell you to keep paying a weekly Class 2 charge. Employed doctors (salaried GPs and consultants) pay Class 1 through PAYE on their employment income instead.

Getting Specialist Advice

Doctors often have mixed NHS and private income, an NHS pension annual-allowance position to watch, and a choice between trading personally or through a company. A specialist medical accountant can identify every legitimate claim, keep you compliant and model the bigger decisions (incorporation, pension, premises) properly rather than in isolation.

Consider advice in particular if you have mixed NHS and private income, work through a limited company, or have significant equipment or premises costs. Our specialist medical accounting services help doctors across the UK claim correctly and stay compliant. This article is general information, not personal tax advice.
