Accounting for Dental Practices

Running a dental practice in the UK involves a unique set of accounting challenges. Whether you are an NHS contractor, a purely private practice or a mix of both, the way income flows, how associates are paid and the VAT treatment of dental services all require careful handling.

Business structures for dentists

The structure you choose affects how you are taxed, your personal liability and your administrative burden.

Most high-street dental practices operate as sole trader or partnership structures. Corporate dental groups typically use limited companies. The critical distinction between a principal (who holds the NHS contract or owns the practice) and an associate (who is self-employed and works under a contract for services) has significant accounting implications.

NHS income and UDA payments

If you hold an NHS contract, your income is based on Units of Dental Activity (UDAs). The value of each UDA varies by contract and region, but the mechanism is the same everywhere.

How NHS payments work

• Your Local Area Team (part of NHS England) pays you monthly based on your contracted UDA target
• Payments are made in twelfths of the annual contract value
• At year end, an end-of-year reconciliation compares delivered UDAs against the target
• If you under-deliver, NHSE claws back a proportion of the payments
• If you over-deliver, you do not automatically receive more (the contract is capped)

Recording NHS income

Record each monthly payment from the NHS as income when received. At year end, account for any clawback as a reduction in income. If a clawback straddles your accounting year end, you need to make a provision in your accounts for the expected repayment.

Private income

Private income comes from treatments not covered by the NHS, including cosmetic dentistry, implants, orthodontics and whitening. Private income is typically higher-margin but less predictable than NHS income.

If you operate a capitation plan (where patients pay a monthly fee for ongoing care), recognise the income over the period it covers rather than when the cash arrives.

Associate dentist pay

Associate dentists are almost always self-employed. They work under a contract that specifies the percentage split of NHS UDA income and/or private fees.

Typical arrangements

• NHS work – the associate receives a percentage (commonly 45-50%) of the UDA value for treatments they deliver
• Private work – the associate receives a percentage (commonly 50%) of private fees they generate
• The practice retains the remainder to cover overheads (premises, staff, materials, equipment)

Tax treatment

Because associates are self-employed, the practice does not deduct PAYE or National Insurance from their payments. Associates file their own Self Assessment returns and are responsible for their own tax, NIC and pension contributions.

The practice should issue a monthly or quarterly statement showing gross fees generated, the percentage retained and the amount paid to the associate. Keep these records carefully – HMRC occasionally challenges the self-employed status of dental associates, though the 2018 case of Ralc Consulting Ltd v HMRC largely confirmed the traditional self-employed model.

VAT for dental practices

Most dental treatment is exempt from VAT under Group 7, Schedule 9 of the VAT Act 1994. This means you do not charge VAT on:

• All clinical dental treatment (NHS and private)
• Dental prosthetics (crowns, bridges, dentures) supplied as part of treatment

However, some supplies are subject to VAT at 20%:

The input VAT problem

Because most dental income is VAT-exempt (not zero-rated), you cannot recover input VAT on your purchases. This means the VAT you pay on equipment, materials, repairs and professional fees is a genuine cost to the business.

If you have a mix of exempt and taxable supplies, you may need to do a partial exemption calculation to work out how much input VAT you can reclaim. For most practices where taxable supplies are minimal, this recovery will be small.

Allowable expenses

Dental practices have sector-specific expenses beyond the usual business costs.

Clinical expenses

• Dental materials and consumables (composite, amalgam, impression materials, anaesthetics)
• Laboratory fees for crowns, bridges and dentures
• Disposable items (gloves, masks, suction tips, bibs)
• Decontamination and sterilisation supplies

Premises and equipment

• Rent or mortgage interest on the surgery premises
• Business rates (check eligibility for small business rates relief)
• Dental equipment (chairs, handpieces, X-ray units, compressors) – claim capital allowances
• Equipment maintenance and repairs
• Utilities (electricity, gas, water)

Professional costs

• GDC registration (currently £680 per year for dentists)
• Indemnity cover (dental defence organisations or commercial insurance)
• CQC registration fees
• CPD courses and conferences
• Professional subscriptions (BDA, specialist societies)

Staff costs

• Dental nurses, hygienists, therapists – salaries, employer NIC, pension contributions
• Receptionists and practice managers
• Locum costs when covering for holidays or sickness

Pension planning for dentists

NHS Pension Scheme

If you do NHS work, you (and your associates doing NHS work) are eligible for the NHS Pension Scheme. This is a defined benefit scheme and is generally considered one of the best pensions available. Contributions are tiered based on earnings.

The employer (practice) contribution is 23.7%. For associates, their contribution is based on the NHS income they generate.

Be aware of the annual allowance (£60,000) and lifetime allowance (abolished from April 2024 but transitional protections still apply). High-earning dentists with significant NHS pension accrual should review their position annually to avoid unexpected tax charges.

Private pension for non-NHS income

For income from private work, you need to make your own pension arrangements . A SIPP (Self-Invested Personal Pension) gives flexibility and control. Contributions reduce your taxable income, making this one of the most effective tax-planning tools available.

Superannuation and year-end returns

NHS dental practices must submit annual returns for superannuation purposes. These returns detail:

• Total NHS income generated by each performer (principal and associate)
• Pension contributions deducted
• Reconciliation with the contract value

Deadlines are strict and penalties apply for late submissions. Your accountant or practice manager needs to coordinate closely with the NHS BSA (Business Services Authority) to ensure figures match.

Record-keeping essentials

Beyond the standard HMRC requirements, dental practices should maintain:

• Day sheets or clinical software records showing treatments delivered, fees charged and payment method
• Associate statements with gross fees, percentage split and net payment
• Lab work log matching lab invoices to specific patients and treatments
• Stock records for high-value materials
• Equipment asset register for capital allowances claims
• CQC compliance records (not strictly accounting, but linked to operational costs)

Common accounting mistakes in dental practices

• Mixing NHS and private income without clear separation – makes profitability analysis and benchmarking impossible
• Not provisioning for UDA clawback – a surprise clawback distorts your accounts and cash flow
• Failing to track associate percentages accurately – errors compound monthly and create disputes
• Overlooking capital allowances on expensive equipment like digital X-ray units, CBCT scanners and CAD/CAM systems
• Not claiming all professional fees – GDC registration, indemnity cover and CPD are all deductible but frequently forgotten by associates on Self Assessment returns
• Ignoring pension annual allowance – high earners with both NHS pension and private pension contributions can breach the £60,000 limit and face a tax charge
