If you are a GP in the UK, one of the first questions you will ask yourself is simple but important: what expenses can a GP claim against tax? The short answer is that if you’re a locum, you can claim almost anything, as long as it is “wholly and exclusively” for your medical work.
That includes things like medical equipment, professional fees, and indemnity insurance. But you have to be careful if you are a salaried GP. Because the rules for you are now much more restrictive.
This guide breaks down exactly what expenses can a GP claim so you can maximise your net income.
Let’s start with the basics!
Locum vs Salaried GPs: Why It Matters
Your working structure has a big impact on what expenses can a GP claim. Because of this, your contract type is the first thing you need to check.
If you are a locum GP, you are generally treated as self-employed. This gives you more flexibility. And you can claim a wider range of GP allowable expenses, as you are effectively running your own business.
If you are a salaried GP, the situation is different. You can still claim some costs, but it is often through medical professional tax relief rather than full business deductions. The scope is narrower, and the process feels less direct.
Therefore, understanding your status is key to making the most of GP tax deductible expenses in the UK.
What Does “Wholly and Exclusively” Actually Mean?
This principle sits at the heart of all GP allowable expenses. For a GP, it means an expense must be incurred only for the purpose of your work in order to be deductible.
However, if an expense has a dual purpose (partly personal, partly professional), you can still claim the professional portion.
For example, if you’re a locum:
- A laptop used 70% for work → you can claim 70% of the cost
Specialist medical accountants can help you calculate these splits correctly. They make sure you are not overclaiming or underclaiming.
What Expenses Can a GP Claim Against Tax?
Let’s look at what expenses can a GP claim:
1. Professional Subscriptions and Memberships
One of the easiest wins for medical professional tax relief is your professional memberships. If you pay for these yourself and they are a requirement of your role, HMRC almost always allows them.
You can claim:
- GMC registration fees
- Medical defence organisation subscriptions
- Royal College memberships
- Approved professional union fees (such as the BMA).
2. Medical Equipment and Clothing
Whether you are a locum or a partner, the tools you use to treat patients are essential doctor business expenses. If you buy a new stethoscope, a diagnostic set, or even a specialised medical bag, you can claim the cost.
For larger items like laptops used for remote consultations or expensive medical machinery, you’ll probably need to use Capital Allowances. The Annual Investment Allowance (AIA) is still there for you. You can deduct 100% of the professional side of the cost in the year you buy it.
And when it comes to clothes, you cannot claim for “everyday” clothes like a suit or a dress. However, if you have a branded uniform or specialist protective gear (PPE), the cost and the laundering of these items are eligible for medical professional tax relief.
3. Medical Indemnity Insurance
Medical indemnity is one of the largest expenses GPs face. It is also fully deductible against tax. Whether you are with the MDU, MPS, or MDDUS, the full annual premium counts as a doctor business expense for HMRC purposes. Locum GPs often pay particularly high premiums. So ensuring this is included in what expenses can a GP claim is important for your finances.
4. Travel, Mileage, and Motoring Costs
Travel is a major part of many GPs’ lives. But it is also where many mistakes happen. When looking at GP tax deductible expenses in the UK, let’s be precise.
What you can claim:
- Travel between your surgery and patient home visits, nursing homes, and hospitals (if relevant to your practice)
- Travel to CPD events, practice meetings away from your usual workplace
- If you are a locum GP, you can claim travel to locum assignments if the surgery is a temporary workplace (typically where you work for less than 24 months).
What you cannot claim:
- Ordinary commuting from your home to your main place of work (your surgery). This is a personal expense in HMRC’s view.
5. Training and Continuing Professional Development (CPD)
When looking at what expenses can a GP claim, this is an important category for staying compliant with GMC requirements. For locums, GP allowable expenses include the cost of maintaining and updating your clinical skills. However, salaried GPs generally cannot claim these personally unless the training is a mandatory contractual requirement.
This covers:
- CPD courses and conference registration fees or course materials
- Clinical training relevant to your current role
- E-learning platforms used for professional development
- Journals and medical textbooks
Remember that you cannot claim for any training that prepares you for a new career. The same applies to qualifications that move you into a totally different field of work
The course must relate to your existing practice.
6. Home Office Expenses
If you are a salaried GP, you can no longer claim tax relief for working from home. HMRC has abolished this for the 2026/27 tax year. But things are different for GP partners and locums. Because you are self-employed, you can still claim for the use of your home.
If you work at least 25 hours a month from home, you can claim a monthly flat rate as part of your GP tax deductible expenses in the UK:
- 25–50 hours: £10 per month
- 51–100 hours: £18 per month
- 101+ hours: £26 per month
Alternatively, you can work out the exact proportion of your heating, electricity, and insurance. This is calculated based on the specific area of your home you use for work and how much time you actually spend there. Often, the “actual cost” method saves you more money if you have a dedicated study or surgery.
Note: If you claim a room exclusively for business use, it can have capital gains tax implications when you sell your home. This is worth discussing with an accountant before you go down that route.
7. Locum Costs
If you are a GP partner and you need to bring in a locum to cover for you, the cost of that cover is a deductible business expense for the practice. This applies whether you are away for annual leave, off sick, or attending CPD days.
Because it is one of the most significant GP allowable expenses for partnerships, it is usually straightforward to claim. You just need to make sure you keep all your invoices and records in order.

8. Accountancy and Professional Fees
Yes, if you are a locum or partner, you can definitely deduct the cost of hiring an accountant. This is a very common win when looking at GP allowable expenses. The same goes for any legal advice you need, specifically for your medical practice.
This includes:
- Accountancy fees for Self Assessment and practice accounts
- Legal fees for partnership agreements or employment disputes
- Payroll services (if you employ staff)
9. Bank Charges and Finance Costs
If you have a dedicated business bank account (which all GP partners and locums should have), any charges on that account are deductible. You can also claim for interest on a practice loan as long as it is for business purposes. These are basic GP allowable expenses that help reduce your taxable income.
What About the NHS Pension?
For salaried GPs, NHS Pension contributions are usually handled via a ‘Net Pay’ arrangement. It means tax relief is applied automatically at your highest rate before you are paid.
Because of this, you don’t typically need to claim it back on your tax return like you do with other expenses.
But things change if you have a private pension or a freestanding AVC outside of the NHS payroll. You have to record these on your Self Assessment to get any higher-rate tax relief you are owed. It is a great detail that is easy to miss. Therefore, it is worth double-checking that this has been handled correctly each year.
Common Mistakes GPs Make with Tax Expenses
Even when doctors understand what expenses can a GP claim, errors happen. Common mistakes include:
- Forgetting the GMC fee: It is fully deductible, but often missed
- Not tracking mileage: Home visits and CPD travel add up fast over a year
- Mixing personal and practice finances: It makes it much harder to separate legitimate claims
- Missing the locum cost deduction: GP partners sometimes absorb locum costs without claiming them
- Overclaiming home office: Without good evidence, this can trigger an HMRC enquiry
- Not claiming accountancy fees: If you’re a locum or partner, they are deductible. Therefore, do not miss out on claiming them.
Why Accurate Claims Matter

Many GPs find the balance between NHS and private income confusing. That is why working with specialist healthcare accountants is often the simplest way forward.

The Bottom Line
So, what expenses can a GP claim? In most cases, if you’re a locum, you can claim costs that are “wholly and exclusively” for your work. If you’re salaried, the rule is even harder. It has to be “necessary” for the job.
When your GP allowable expenses are properly understood and recorded, your tax position becomes clearer and fairer. In case you ever feel unsure, getting a second opinion can quietly save both time and money.
