Doctor tax in one paragraph: NHS doctors pay PAYE on NHS salary plus often complex extras (Clinical Excellence Awards, Discretionary Points, on-call). Private practice is normally either self-employed (sole trader) or through a Ltd company. Locum sessions add a third self-employment stream. Three high-impact considerations: annual allowance breaches (Scheme Pays may be needed), McCloud remedy elections (deadline approaching for many), and full claim of deductible professional expenses (GMC, MDU/MPS, BMA, CPD, journals) which surprisingly few doctors do completely.
NHS income — what's actually taxable
For a typical NHS consultant, the income components are:
- Basic salary per pay scale (e.g., consultant £93k-£127k in 2026/27)
- Clinical Excellence Awards (CEA) / Local Awards — pensionable, taxable as employment income
- Discretionary Points (legacy 1995/2008 schemes) — pensionable
- Additional Programmed Activities (APAs) / Waiting List Initiative — taxable as employment income, may not be pensionable
- On-call and emergency cover — taxable
- Educational Supervision payments — taxable
All of these flow through PAYE under one tax code. The complication arises when you hit higher-rate band, additional-rate band, or breach the pension annual allowance.
The NHS Pension Scheme — three schemes in one career
Most consultants currently active hold deferred benefits in two or three NHS pension schemes:
- 1995 section (final salary) — joined before April 2008. Closed to new accrual from April 2022.
- 2008 section (final salary, slightly different formula) — April 2008 to March 2015. Closed to new accrual from April 2022.
- 2015 CARE scheme (career average, revalued by CPI+1.5%) — from April 2015. Currently the only active scheme.
McCloud judgment: the 2015 transfer to CARE was ruled discriminatory. The "remedy" period (April 2015 to March 2022) is being rolled back into the legacy scheme for affected members. From October 2023, members can choose between 1995/2008 and 2015 treatment for the remedy period. The choice matters for annual allowance calculations and for benefits at retirement.
Practical impact: many consultants have new pension tax statements for the remedy period that produce different annual allowance numbers from what they previously reported. Some discover historic AA breaches; others get refunds. Doctors should review their TRS (Total Reward Statement) for 2015-2022 in light of the remedy.
The annual allowance trap
The pension annual allowance limits the tax-relieved pension input each year. 2026/27 cap: £60,000 standard, with taper down to £10,000 for very high earners (threshold income £200,000 + adjusted income £260,000).
NHS doctors are uniquely exposed because:
- Final-salary schemes treat any pensionable promotion or merit-award uplift as a multiplier on past service — generating large "input amount" in a single year
- CARE scheme inputs are revalued by CPI+1.5% which can be sizeable in inflationary years
- Combined NHS + private pension contributions easily exceed £60k for consultants
The Scheme Pays mechanism lets the NHS pension scheme pay the AA charge directly out of your future pension benefits, in exchange for a reduction in those benefits. This avoids a large personal tax bill but reduces your retirement income.
Critical 2026/27 dates: AA charge for 2024/25 is reported on the 2024/25 Self Assessment (deadline 31 January 2026) — you may need to elect Scheme Pays by 31 July 2026 for that year.
Private practice income
Most consultants with private practice operate as either:
- Sole trader: simpler, all profit taxed at marginal rate, Class 4 NI 6% above £12,570 + 2% above £50,270
- Limited company: CT 19-25% depending on profit level, then dividend extraction. Often paired with employer pension contributions to manage personal income
For private earnings under £30,000/year, sole trader is usually simpler and just as efficient. For sustained earnings above £50,000, Ltd company can save 5-10% effective rate through pension contributions and retained reserves.
Critical: many private hospitals and clinics now require Ltd-company structure or IR35-compliant umbrella for engagement. Check before committing to sole trader.
Locum work — usually self-employed
Locum doctors are usually engaged as self-employed (1099-equivalent) rather than as employees. Practical tax impact:
- Register for Self Assessment within 3 months of starting
- Class 2 NI removed from April 2024 — only Class 4 NI applies now
- Claim mileage between assignments (not from home to permanent workplace) at 45p/mile up to 10,000 miles, 25p after
- Subsistence and overnight costs claimable for genuine business travel
- Professional indemnity insurance fully deductible (MDU, MPS, MDDUS premiums)
- VAT exemption: medical services to patients are VAT-exempt under the medical exemption, so locum doctors don't usually need to register
Locum agency engagement: if you work through an umbrella, you're typically PAYE'd by them — losing the self-employment expense flexibility. Direct engagement with clinics keeps you self-employed.
Deductible expenses most doctors under-claim
| Expense | Typical annual claim | Notes |
|---|---|---|
| GMC annual registration | £433 | Fully deductible if working as a doctor |
| Defence society (MDU/MPS/MDDUS) | £300-£8,000+ | Fully deductible. Higher for surgeons / obstetricians |
| BMA / Royal College subscription | £500-£700 | Deductible if HMRC List 3 approved (most are) |
| Professional journals | £100-£500 | Deductible if relevant to your role |
| CPD courses | £500-£5,000 | Deductible if to maintain (not extend) skills |
| Specialist equipment (e.g., stethoscope) | £100-£500 | Deductible if work-specific |
| Home office (private practice admin) | £312/year flat rate | £6/week simplified expenses |
| Indemnity (additional for private) | £500-£3,000 | Deductible |
Doctors with both employed (NHS) and self-employed (private) income can claim expenses against the relevant income stream. GMC subscription, for example, can be claimed via Self Assessment against employment income using box 19 of the SA102.
Worked example: senior NHS consultant with private practice
Mr K is a consultant cardiologist with £140,000 NHS salary, NHS pension input ~£42,000, private practice profits £80,000 (sole trader). No prior AA carry-forward.
- Total taxable income: NHS £140,000 + private £80,000 = £220,000
- Threshold income: £220,000 (no personal pension contributions to deduct)
- Adjusted income: £220,000 + £42,000 NHS pension input = £262,000
- Tapered annual allowance: £60,000 - (262,000 - 260,000) / 2 = £59,000
- Pension input vs AA: £42,000 vs £59,000 → no breach, but close
- Income tax + NI: roughly £88,000 combined
- Effective rate: ~40%
If Mr K earned another £20,000 of private profit, his adjusted income would push him to £282,000 — tapered AA would be £49,000. With NHS input £42,000, no breach. But if he received a CEA award uplifting pension input to £55,000, he'd breach by £6,000 and owe ~£2,400 in AA charge.
Common doctor tax mistakes
- Not claiming all professional subscriptions. GMC + Royal College + defence society + BMA can easily be £2,000-£10,000 of deductible expense missed.
- Missing Scheme Pays elections. AA charges paid personally cost twice as much as Scheme Pays-discounted pension benefits in present value terms.
- Treating private practice as a "hobby". Once private earnings exceed £1,000 trading allowance, you must declare via Self Assessment. Many consultants under-declare in the first year.
- Wrong wrapper for private practice. Sole trader for sustained >£50k income or Ltd for under £30k both leave money on the table.
- Ignoring McCloud remedy. The remedy choice (1995/2008 vs 2015 for the 2015-2022 period) can be worth £20k-£100k in retirement benefits. Many doctors are letting the default decision stand without consideration.
