Why a General Accountant May Not Be Enough for Your Dental Practice

Every UK dentist needs an accountant. But not every accountant understands dentistry. The difference between a general practice accountant and a dental accountant is not just a marketing label. It is the difference between someone who files your tax return and someone who can tell you whether your UDA contract is profitable, whether your associate is genuinely self-employed, and how to structure a practice purchase to minimise capital gains tax.

Dentistry has its own tax rules, its own pension scheme, its own contract types, and its own valuation methods. A general accountant who works with plumbers, retailers, and consultants will not know these. They will apply standard SME rules, which can cost you thousands in missed reliefs or, worse, trigger an HMRC enquiry.

This article explains the specific areas where a dental accountant adds value that a generalist cannot replicate. If you are an associate, a principal, a locum, or a practice buyer, the differences matter.

UDA Contracts and NHS Contract Mechanics

NHS dental contracts are not standard commercial contracts. They are governed by the NHS (General Dental Services Contracts) Regulations 2005 in England, with equivalent frameworks in Wales, Scotland, and Northern Ireland. The core unit is the UDA (Unit of Dental Activity), but UDA values vary by individual contract. The England average is roughly £25 to £35 per UDA, but individual contracts range from £15 to £45 depending on region, historical negotiation, and contract type [1].

A general accountant will see "UDA income" on your profit and loss account and treat it as ordinary turnover. A dental accountant will ask: What is your UDA value? How many UDAs are you contracted to deliver? What is your breach threshold? Are you carrying forward underperformance? These questions affect cash flow forecasting, tax planning, and practice valuation.

For practice owners, the interaction between UDA delivery and NHS pensionable earnings is another specialist area. The NHS Pension Scheme uses pensionable earnings, which include NHS contract income but not private fee income. A dental accountant can model the impact of taking on additional UDAs versus private work on your pension benefits. A generalist will not know to ask.

NHS Pension Scheme: Three Sections and the McCloud Remedy

The NHS Pension Scheme has three sections: the 1995 section (closed to new members), the 2008 section (closed to new members), and the 2015 CARE section (current). Many dentists who joined before 2015 still hold benefits in the legacy sections. The McCloud remedy means that members who had benefits in the 1995 or 2008 sections between 1 April 2015 and 31 March 2022 can choose at retirement which scheme rules apply to that remedy period.

This is not a simple election. The choice depends on projected final salary, career average revaluation, and the member's age and retirement plans. A dental accountant who understands the NHS Pension Scheme can help you model the options. A general accountant will not know the difference between a 1995 section member and a 2015 section member, let alone the McCloud remedy.

Employer pension contributions are not P11D-reportable benefits in kind. They are an allowable trade expense for the practice and tax-free for the recipient up to the annual allowance. A generalist might incorrectly report them, or fail to advise on annual allowance tax charges when NHS pension growth exceeds the standard annual allowance of £60,000 (tapered for high earners).

Associate Self-Employment Status: Facts Over Paperwork

Many associates work under a BDA model associate agreement and believe that guarantees self-employed status. It does not. HMRC and tribunals determine status by looking at actual working practice: control, substitution, mutuality of obligation, financial risk, and integration. The paperwork is secondary.

A dental accountant will review your working arrangements: Do you choose your own hours? Can you send a substitute? Do you bear financial risk if a patient does not pay? Do you provide your own materials? These factors determine whether you are self-employed or an employee for tax purposes. A general accountant who does not know the dental case law (such as the recent HMRC wins against associate dentists) may assume the BDA agreement is sufficient. That assumption can lead to a retrospective tax bill for unpaid PAYE and NIC.

For practice owners, the risk is employer NIC and penalties if HMRC reclassifies an associate as an employee. A dental accountant can advise on contract terms and working practices that support self-employment status, and can help you defend a status review if HMRC challenges it.

Goodwill Valuation and Tax Relief on Acquisition

Dental practice goodwill is typically valued at 60-80% of the total purchase price. Valuation methods include earnings-based multiples (commonly 0.6 to 1.4 times adjusted EBITDA, depending on NHS/private mix and region) and rule-of-thumb percentages of fee income (roughly 25-60% depending on practice type).

When you buy a practice through a company, goodwill acquired post-1 April 2019 qualifies for tax relief at 6.5% per year under the Finance Act 2019. Goodwill purchased between 8 July 2015 and 31 March 2019 generally has no tax relief. A dental accountant will structure the purchase to maximise relief. A generalist may not know the relief exists, or may incorrectly assume all goodwill amortisation is tax-deductible.

Section 162 incorporation relief (TCGA 1992 s.162) allows you to defer capital gains tax when you transfer an unincorporated dental practice to a company in exchange for shares. The relief requires the whole business to be transferred. A dental accountant can advise on whether incorporation is right for you and how to structure the share consideration. A generalist may not know the relief exists at all.

VAT on Dental Treatment: Exempt but Not Always

Treatment by a registered dental professional carried out in the course of their profession is exempt from VAT under VATA 1994 Schedule 9 Group 7. This includes both NHS-funded and privately paid treatment. But purely cosmetic services without a medical purpose can be standard-rated. Tooth whitening is a known borderline case that HMRC scrutinises.

A dental accountant will know the exemption rules and can advise on whether your cosmetic services are exempt or standard-rated. They will also know that the VAT registration threshold is £90,000 (raised from £85,000 on 1 April 2024). If your private income exceeds this threshold, you must register for VAT even if most of your income is exempt. Partial exemption calculations for mixed practices are complex. A general accountant may not know the dental-specific VAT rules and could file incorrectly.

Capital Allowances on Dental Equipment and Fixtures

Dental chairs, lights, compressors, suction units, autoclaves, and X-ray machines (including OPGs) typically qualify for the Annual Investment Allowance (AIA) of £1,000,000, giving 100% tax relief in the year of purchase. Cars and buildings do not qualify for AIA.

When you buy a practice with existing fixtures, you need an election under CAA 2001 s.198 to agree the value of qualifying fixtures with the seller. Without this election, you may lose capital allowances on those assets. A dental accountant will ensure the election is made and the values are agreed. A generalist may not know the election exists.

Structures and Buildings Allowance (SBA) gives 3% per year straight-line relief on qualifying construction or acquisition costs of practice premises built or acquired after 29 October 2018. This is separate from plant and machinery allowances. A dental accountant will identify SBA-eligible costs in a practice purchase. A generalist may overlook them.

Locum Dentists and IR35

Locum dentists working through a personal service company (PSC) are subject to off-payroll IR35 rules if the engaging practice is a medium or large client. Since 6 April 2021, the practice (not the locum's PSC) determines IR35 status for medium and large clients. If the status is inside IR35, the practice must deduct PAYE and NIC from the locum's fees, even though the locum invoices through their company.

A dental accountant will advise locums on whether their engagements are likely inside or outside IR35, and on the tax implications of each. They will also advise practices on their obligations as the fee-payer. A general accountant may not know that the off-payroll rules apply to dental locums, or may assume that a PSC structure automatically avoids IR35.

Spouse Employment and Market Rate Wages

Many dental practices employ a spouse for administrative or nursing work. HMRC frequently challenges these arrangements. To be deductible, the spouse must be paid a genuine market rate for genuine work. A dental accountant will advise on what constitutes a market rate for the role, how to document the employment, and how to avoid HMRC challenge. A generalist may accept whatever figure the practice owner suggests, which can lead to a disallowance and penalties.

Practice Profit Extraction: Partnership vs Limited Company

Dental practices can operate as sole traders, partnerships, or limited companies. The optimal structure depends on profit level, NHS/private mix, pension contributions, and exit plans. Corporation tax rates are 19% for profits up to £50,000 and 25% for profits above £250,000, with marginal relief between. Dividend tax rates are 8.75% (basic rate), 33.75% (higher rate), and 39.35% (additional rate), with a £500 dividend allowance.

A dental accountant will model the tax position under each structure, including employer NIC, dividend tax, and pension contributions. They will also consider the impact of the NHS Pension Scheme annual allowance and the tapered personal allowance for high earners. A generalist may default to a limited company structure without considering the dental-specific factors.

Practice Sale and Business Asset Disposal Relief

Selling a dental practice is a capital disposal, not trading income. Gains are subject to capital gains tax, with Business Asset Disposal Relief (BADR) available if conditions are met. BADR gives a 14% rate for 2025/26, rising to 18% from 6 April 2026. The lifetime limit is £1 million.

A dental accountant will structure the sale to maximise BADR eligibility, including ensuring the practice is a trading business and that the seller meets the ownership and officer/employee conditions. They will also advise on the interaction between goodwill value, property value, and the BADR limit. A generalist may not know the BADR rules or may incorrectly assume all practice sales qualify.

Professional Subscriptions and Tax Relief

Dentists can claim tax relief on annual subscriptions to approved professional bodies, including the General Dental Council, the British Dental Association, and dental defence organisations (MDU, Dental Protection, MDDUS). HMRC maintains a list of approved professional organisations and learned societies (List 3), last updated on 29 April 2026 [2]. You cannot claim relief on life membership subscriptions or on fees paid by your employer [2].

A dental accountant will ensure you claim the correct relief and that subscriptions are not duplicated in your accounts. A generalist may not know which organisations are on the approved list.

CPD Costs and Other Allowable Expenses

Continuing professional development (CPD) costs are allowable if professionally relevant. The GDC requires 100 verifiable hours over 5 years [3]. Costs include course fees, travel, accommodation, and materials. A dental accountant will advise on what qualifies and how to document it. A generalist may disallow costs that are perfectly allowable, or allow costs that are not.

Why Specialist Knowledge Matters

The dental sector has its own accounting and tax rules. A general accountant who works across multiple industries cannot be expected to know the nuances of UDA contracts, NHS pension sections, goodwill amortisation relief, associate IR35 status, and dental VAT exemptions. The risk of error is high, and the cost of error can be significant: a missed relief, an incorrect filing, or an HMRC enquiry.

A dental accountant brings sector-specific knowledge that reduces risk and optimises your tax position. Whether you are an associate, a principal, a locum, or a practice buyer, the difference matters.

If you are unsure whether your current accountant understands dentistry, ask them: What is the current UDA value range in your region? What is the McCloud remedy? What is the tax relief rate on goodwill acquired post-1 April 2019? If they cannot answer, it may be time to switch.
