Are you actually self-employed?

Before claiming anything, you need to be clear about your employment status. Many NHS doctors and dentists are employed by a trust or practice, but also take on additional self-employed work such as locum shifts, private clinics or associate positions. Your tax deductions only apply to the self-employed income, not your employed earnings.

Dental associates are a common example. Most associate dentists are self-employed under a contract with the principal dentist, which means they are responsible for their own tax and National Insurance through self assessment. Locum GPs and private doctors typically fall into the same category.

HMRC looks at the actual working arrangement, not just what your contract says. If you set your own hours, bear financial risk and work for more than one client, you are likely to be genuinely self-employed. If you are uncertain, seek advice before you file.

Professional fees and subscriptions

Any fees you pay to professional bodies that are required for your work are fully deductible. For doctors and dentists, this typically includes:

• General Medical Council (GMC) registration fees
• General Dental Council (GDC) registration fees
• British Medical Association (BMA) membership
• British Dental Association (BDA) membership
• Royal College membership fees where required for your role
• Specialist society subscriptions that are relevant to your practice

HMRC allows deductions for subscriptions on approved lists, and most major medical and dental professional bodies qualify. Check the HMRC list of approved professional organisations if you are unsure about a specific body.

Medical indemnity insurance

Indemnity insurance is not optional in healthcare. Premiums paid to organisations such as the Medical Defence Union (MDU), the Medical Protection Society (MPS) or Dental Protection are fully deductible against your self-employed income. This is often one of the largest single deductions for self-employed clinicians, so make sure you are capturing the full annual premium, including any specialist or out-of-hours extensions you pay for separately.

Equipment and instruments

The cost of clinical equipment used in your self-employed work is deductible, either in full through the Annual Investment Allowance (AIA) or through capital allowances over time. For most self-employed doctors and dentists, the AIA limit is more than sufficient to cover the full cost in the year of purchase.

Common examples include:

• Dental drills, handpieces and ultrasonic scalers
• Diagnostic equipment such as ophthalmoscopes and otoscopes
• Portable monitoring equipment for locum or domiciliary work
• Sterilisation equipment
• Computer hardware and tablets used for clinical records or billing
• Stethoscopes and other personal clinical tools

Equipment that is used partly for personal purposes must be apportioned. Only the business-use proportion is deductible.

Premises and room rental

If you rent a room or clinic space to see patients, the rental cost is fully deductible. This applies whether you pay a daily chair rental to a principal dentist, rent a consulting room at a private hospital or lease your own clinical premises. The cost must relate directly to your self-employed income.

Other premises-related costs that qualify include:

• Business rates on your own premises
• Utilities (electricity, water, heating) for clinical premises
• Cleaning and waste disposal, including clinical waste contracts
• Repairs and maintenance to your premises
• Contents insurance for your practice

Staff costs

If you employ a receptionist, dental nurse, practice manager or any other member of staff to support your self-employed work, their wages, employer National Insurance contributions and any pension contributions you make on their behalf are all deductible. In 2026/27, employer National Insurance is charged at 15% on earnings above £5,000 per employee, so good planning around staffing costs matters.

If you use an agency to supply temporary nursing or administrative staff, those agency fees are deductible too. NDCA’s payroll service can handle payroll obligations for any staff you employ, including real-time information (RTI) submissions to HMRC.

Travel and motor expenses

Travel between different work locations is deductible, but travel between your home and a single regular place of work is not. For locum doctors and dentists who work across multiple sites, most of their travel will qualify.

Using your own vehicle

If you use your own car, van or motorcycle for work journeys, you can either claim the HMRC approved mileage rates or claim the actual costs of running the vehicle (fuel, insurance, servicing, road tax) apportioned to business use. Most self-employed clinicians find the mileage rate simpler. Check the latest HMRC guidance for current approved mileage rates, as these are not listed in the 2026/27 rates confirmed above.

Other travel costs

Train tickets, bus fares, taxis and parking costs incurred on business journeys are all deductible. If you travel overnight for work, reasonable accommodation and subsistence costs also qualify, subject to HMRC’s benchmark rates.

Continuing professional development and training

Costs that maintain or update your existing professional skills are deductible. For doctors and dentists, this is a broad category that includes:

• CPD courses required to maintain GMC or GDC registration
• Medical or dental conferences and seminars
• Specialist training days relevant to your current practice area
• Clinical textbooks and journals
• Online learning platforms used for clinical development

Training that leads to a new qualification or allows you to move into a completely different area of practice is generally not deductible, as HMRC treats it as capital expenditure on a new skill rather than maintenance of an existing one. The line can be blurry, so keep the course details and check with your accountant.

Pension contributions

Many NHS doctors and dentists are members of the NHS Pension Scheme. If you are self-employed and contributing to the NHS scheme as a practitioner, those contributions reduce your taxable profits. If you also contribute to a private pension such as a SIPP, you receive tax relief on those contributions too.

In 2026/27, the pension annual allowance is £60,000. This covers both employer and personal contributions across all pension schemes. NHS clinicians need to take care here because the NHS Pension Scheme is a defined benefit scheme and HMRC calculates its value using a specific formula. Annual allowance charges can catch NHS doctors by surprise when their pensionable pay rises significantly, so review your position each year.

Use of home as office

If you do administrative work at home, such as writing referral letters, completing clinical notes, billing patients or doing your accounts, you can claim a proportion of your home running costs. HMRC allows a flat rate of £6 per week without the need for evidence, or you can calculate the actual proportion of your home costs that relate to business use based on time and floor area.

For most self-employed doctors and dentists, the actual cost method usually produces a larger deduction, but it requires more detailed records. Your accountant can help you decide which approach is more beneficial.

VAT and healthcare exemptions

Most medical and dental services provided to patients are exempt from VAT under the UK’s welfare exemption for healthcare. This means you do not charge VAT on patient fees, but it also means you cannot reclaim VAT on your costs in the same way a fully VAT-registered business can.

The VAT registration threshold in 2026/27 is £90,000. If your taxable (non-exempt) income exceeds this, you must register. For most clinicians whose income is purely from clinical services, this threshold will not be reached for VAT purposes because exempt income does not count towards it. However, if you have other income streams such as training, speaking fees or medico-legal report writing, those may be taxable for VAT purposes and could push you over the threshold.

VAT in healthcare is genuinely complex. If you have mixed income streams, speak to NDCA about whether you need to register and what partial exemption means for your business. Our team handles VAT returns for healthcare professionals regularly.

Record keeping and self assessment

All of these deductions are only useful if you have the records to support them. HMRC can ask for evidence of any claim going back several years, so keeping invoices, receipts and bank statements is not optional.

From April 2026, Making Tax Digital for Income Tax applies to self-employed individuals and landlords with income over £50,000. Many self-employed doctors and dentists will be caught by this from the start. It requires digital record keeping and quarterly updates to HMRC through compatible software.

NDCA’s bookkeeping service keeps your records accurate, up to date and MTD-compliant throughout the year. If your records are behind, our bookkeeping catch-up service can bring everything up to date quickly before your tax return is due.

Your annual self assessment tax return must include all self-employed income and expenses, your NHS income if applicable, dividend income, savings interest and any rental income. Missing any of these can result in penalties and interest.

Should you trade through a limited company?

Some self-employed doctors and dentists choose to operate through a limited company, particularly where income is high or where they want to retain profits for future investment. Through a limited company, profits are subject to corporation tax at 19% (on profits under £50,000) or 25% (on profits over £250,000) in 2026/27, rather than income tax at up to 45%. Directors can then extract income as a combination of salary and dividends, which can be more tax-efficient.

However, operating through a limited company brings additional obligations including filing annual accounts at Companies House, corporation tax returns, payroll obligations and more complex bookkeeping. It is not the right structure for every clinician, and the NHS Pension Scheme access question adds another layer of complexity for doctors and dentists who want to maintain their NHS pension contributions.

If you are considering company formation, take advice before you act. The tax savings need to outweigh the additional costs and complexity.

NDCA works with a wide range of healthcare professionals and can model both structures for your specific income level and circumstances.

Frequently asked questions

Can a self-employed dentist claim their GDC registration fee?

Yes. GDC registration is a legal requirement to practise as a dentist in the UK, so the annual fee is fully deductible as a professional subscription against self-employed income.

Can I claim my medical indemnity insurance as a tax deduction?

Yes. Premiums paid to organisations such as MDU, MPS or Dental Protection are fully deductible. This is one of the largest allowable expenses for most self-employed doctors and dentists.

Are NHS pension contributions tax deductible for self-employed GPs?

Yes. GP practitioner contributions to the NHS Pension Scheme reduce your taxable profits from self-employment. The pension annual allowance in 2026/27 is £60,000 across all schemes, so keep track of your total contributions to avoid an annual allowance charge.

Do self-employed doctors need to register for VAT?

Most clinical services are VAT-exempt, so exempt income does not count towards the £90,000 VAT registration threshold in 2026/27. However, if you have taxable income streams such as training fees, medico-legal reports or speaking engagements, those do count. If your taxable income from these activities exceeds the threshold, you must register for VAT.

Can a locum doctor claim travel expenses between different hospitals?

Yes. Travel between different work locations is deductible for locums. If you have no single fixed place of work, travel from home to each site may also qualify. Keep records of each journey, the purpose and the distance or cost.

Should I use a limited company as a self-employed dentist?

It depends on your income level, your NHS pension position and your longer-term plans. A limited company can reduce your overall tax bill if profits are high, but it brings additional costs and compliance obligations. NDCA can model both options for your specific situation before you make a decision.
