Why a General Accountant May Not Be Enough for Your Dental Practice
Dentists in the UK face a set of tax and accounting rules that do not apply to most other small business owners. NHS pension scheme sections, UDA contract values that vary by region, goodwill amortisation rules that changed in 2019, and VAT exemptions that depend on the medical purpose of treatment all create complexity that a general accountant may not recognise. A specialist accountant for dentists works with these rules day in, day out. The difference is not just about knowing the right tax codes. It is about structuring your practice finances to keep more of what you earn, while staying compliant with HMRC and NHS contract requirements.
This article explains the specific areas where a dental-specialist accountant adds value that a general practitioner accountant cannot. We cover NHS pension planning, UDA contract accounting, goodwill tax relief on practice purchase, VAT on mixed NHS and private income, associate self-employment status, and the upcoming Making Tax Digital for Income Tax requirements. Each section includes worked examples with real figures from the 2025/26 tax year.
NHS Pension Scheme: Three Sections and the McCloud Remedy
The NHS Pension Scheme is not a single scheme. Three sections exist: the 1995 section (closed to new members), the 2008 section (also closed), and the 2015 CARE section (current). Many established dentists still hold benefits in the 1995 or 2008 sections. The McCloud remedy means that members who had benefits in legacy schemes between 1 April 2015 and 31 March 2022 can choose at retirement which scheme rules apply to that remedy period. A general accountant may not know these rules exist. A specialist accountant for dentists will factor the McCloud choice into your retirement planning and annual allowance calculations.
The annual allowance for pension contributions in 2025/26 is £60,000, but the tapered annual allowance can reduce this to as low as £10,000 for high earners (adjusted income over £260,000). For dentists with significant NHS pension growth plus private practice income, the taper often bites. A specialist accountant calculates the pension input amount correctly, which requires understanding how the 2015 CARE scheme revalues benefits each year. Getting this wrong can trigger an unexpected annual allowance tax charge of up to 45% on the excess.
UDA Contract Values: Not a Single National Figure
UDA rates vary by individual contract and region. The England average sits around £25 to £35 per UDA, but individual contracts range from £15 to £45 or more. Wales and Northern Ireland use different contract types with different unit values. Scotland uses the Statement of Dental Remuneration (SDR) item-of-service fees, not UDAs at all. A general accountant who assumes a single national UDA value will produce inaccurate profit forecasts and tax projections. A specialist accountant for dentists will ask for your specific contract schedule and calculate based on your actual UDA value.
Consider an associate earning £80,000 gross from NHS work at 2,000 UDAs at £40 per UDA. If the accountant assumes £28 per UDA, the projected income is £56,000, a difference of £24,000. That error affects tax planning, pension contributions, and even mortgage applications. For practice owners, the UDA value directly impacts practice valuation. The NHS UDA value calculator on this site lets you input your contract figures to get an accurate baseline.
Goodwill Amortisation: Tax Relief at 6.5% Per Year
When you buy a dental practice through a limited company, the goodwill you acquire can attract tax relief at 6.5% per year under the Finance Act 2019 rules. This applies to qualifying goodwill acquired after 1 April 2019. Goodwill purchased between 8 July 2015 and 31 March 2019 generally has no tax relief. A general accountant may not know this distinction and could miss the relief entirely, costing you thousands in corporation tax over the amortisation period.
Example: You buy a practice for £500,000, of which £350,000 is goodwill. At 6.5% per year, the annual tax deduction is £22,750. Over 15 years, that is £341,250 in total deductions against corporation tax. At the 19% small profits rate, that saves £64,837.50 in tax. If your accountant misses this, you lose that saving. A specialist accountant for dentists will ensure the purchase agreement allocates the price correctly between goodwill, fixtures, and property to maximise relief.
For sellers, the interaction with Business Asset Disposal Relief (BADR) is critical. BADR applies at 14% for 2025/26, rising to 18% from 6 April 2026. The lifetime limit is £1 million. A specialist accountant structures the sale to qualify for BADR, which requires the practice to be a trading business and the seller to hold at least 5% of shares and be an employee or officer for two years before disposal. General accountants often miss the trading status test for mixed NHS-private practices.
VAT on Dental Treatment: Exempt or Standard-Rated?
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. However, purely cosmetic services without a medical purpose can be standard-rated. Tooth whitening is a known borderline case that HMRC scrutinises. A general accountant may treat all dental income as VAT-exempt, which is wrong for cosmetic work and can lead to penalties for under-declared VAT.
If your practice earns more than £90,000 per year from standard-rated services (cosmetic treatments, report writing, lecturing, selling dental products), you must register for VAT and charge 20% on those supplies. The exempt treatment income does not count toward the threshold, but it does affect your partial exemption calculation if you are VAT-registered. A specialist accountant for dentists will review your income mix, identify which services are standard-rated, and advise on whether voluntary VAT registration makes sense for your practice.
For mixed practices, partial exemption can be complex. You need to apportion input VAT between exempt and taxable supplies. The standard method uses the ratio of taxable to total income. If your practice is predominantly NHS (exempt), you may recover little input VAT. A specialist accountant can apply for a special method if the standard method produces an unfair result. General accountants rarely handle partial exemption for dental practices.
Associate Self-Employment Status: Facts Over Paperwork
HMRC and tribunals determine self-employment status by looking at actual working practice, not the contract. The five key tests are control, substitution, mutuality of obligation, financial risk, and integration. The BDA's model associate agreement does not automatically guarantee self-employed status. Each case rests on the facts. A general accountant may accept the contract at face value. A specialist accountant for dentists will review your actual working arrangements and advise on whether HMRC could challenge your status.
If HMRC reclassifies you as an employee, you face backdated tax, employee NI, and employer NI plus interest and penalties. The employer (the practice) is liable for the employer NI. For a locum working through a limited company, the off-payroll IR35 rules apply from 6 April 2021. If the engaging practice is a medium or large client, the practice determines your IR35 status. Inside-IR35 means the practice must deduct PAYE and NI from your fees, despite your limited company structure. A specialist accountant will help you structure your engagement to stay outside IR35 where the facts support it.
Making Tax Digital for Income Tax: Mandatory from April 2026
From 6 April 2026, Making Tax Digital (MTD) for Income Tax becomes mandatory for sole traders and landlords with gross income over £50,000. This includes self-employed associates and locums. The threshold drops to £30,000 in 2027. MTD requires you to keep digital records and submit quarterly updates to HMRC using compatible software. A general accountant may not have dental-specific MTD software or understand how to handle the quarterly updates for variable UDA income. A specialist accountant for dentists will set up the right software, train you on record-keeping, and manage the quarterly submissions.
The penalty system for MTD is different from the annual Self Assessment late filing penalty. Late submission of a quarterly update attracts a points-based penalty. Each point costs £200 once you reach the penalty threshold (4 points for quarterly submissions). A specialist accountant ensures your quarterly updates are filed on time, avoiding these penalties.
Capital Allowances on Dental Equipment and Fixtures
Dental chairs, compressors, X-ray units (including OPG), autoclaves, suction units, and computers all qualify for capital allowances. The Annual Investment Allowance (AIA) gives 100% relief on qualifying expenditure up to £1 million per year. This covers most dental equipment but not cars or buildings. When you buy a practice with existing fixtures, you need an election under CAA 2001 section 198 to claim capital allowances on those fixtures. Without the election, the seller retains the right to claim, and you lose the relief. A general accountant may not know about the s.198 election. A specialist accountant for dentists will include it in the purchase agreement.
For practice premises built or acquired after 29 October 2018, the Structures and Buildings Allowance (SBA) gives 3% per year straight-line relief on qualifying construction or acquisition costs. This is separate from the AIA and applies to the building structure itself, not the fixtures inside. A specialist accountant will identify which costs qualify for SBA and which qualify for AIA, maximising your total relief.
Spouse Employment: Market Rate or HMRC Challenge
Employing a spouse in the practice is common, but HMRC challenges arrangements where the salary is not at a genuine market rate for the work done. If your spouse works as a receptionist for 10 hours per week, the salary must reflect what you would pay an unrelated receptionist. Paying £30,000 for 5 hours per week of administrative work will be disallowed. A specialist accountant will advise on the appropriate salary level, ensure a proper employment contract exists, and handle the payroll and RTI submissions correctly. General accountants often overlook the market rate requirement and leave you exposed to HMRC enquiries.
Practice Valuation: EBITDA Multiples and Regional Variation
Dental practice valuations use EBITDA multiples that vary by NHS/private mix and region. Private practices typically command higher multiples than NHS-heavy practices. The typical range is 0.6 to 1.4 times adjusted EBITDA. Rule-of-thumb methods use 25% to 60% of fee income depending on the practice type. A general accountant may apply a generic small business multiple, which undervalues or overvalues the practice. A specialist accountant for dentists will use dental-specific valuation methods and benchmark against recent sales in your region.
For sellers, the valuation directly affects the CGT calculation. With BADR at 14% for 2025/26 and rising to 18% in 2026/27, timing the sale matters. A specialist accountant will model the tax outcome under different sale dates and structures (share sale vs asset sale) to minimise the tax bill. General accountants may not consider the BADR rate change or the interaction with the annual exempt amount of £3,000.
Profit Extraction: Dividend Tax vs Salary
For practice owners operating through a limited company, the choice between salary and dividends affects both tax and NI. In 2025/26, the dividend allowance is £500. Dividend tax rates are 8.75% (basic rate), 33.75% (higher rate), and 39.35% (additional rate). Employer NI is 15% on earnings above £5,000 per year. The Employment Allowance of £10,500 can offset employer NI for the first employee, but not for directors of a single-director company. A specialist accountant for dentists will model the optimal salary-dividend mix for your specific circumstances, considering your NHS pension contributions and personal allowance position.
Example: A practice owner with £120,000 profit before tax. Taking a salary of £12,570 (personal allowance) avoids income tax but incurs employer NI of £1,135.50 (15% on £7,570). Taking the rest as dividends of £107,430 incurs dividend tax of £8,750 (basic rate band) plus £19,289 (higher rate band) = £28,039 total. Total tax and NI: £29,174.50. A different mix could reduce this, but the optimal depends on your pension position and other income. A specialist accountant runs these scenarios for you.
Indemnity and CPD: Allowable Expenses
Professional indemnity insurance (MDU, Dental Protection, MDDUS) is an allowable trade expense for self-employed dentists. For employees, it depends on the employment contract. CPD costs, including course fees, travel, and materials, are allowable if professionally relevant. The GDC requires 100 verifiable hours over 5 years. A specialist accountant will ensure you claim these costs correctly and keep the necessary records. General accountants may miss the distinction between employee and self-employed treatment of indemnity costs.
Why a Specialist Accountant Saves You Money
The examples above show that the difference between a general accountant and a specialist accountant for dentists is not marginal. It can amount to thousands of pounds per year in missed reliefs, incorrect VAT treatment, or pension tax charges. The ICAEW provides technical guidance for dentists on accounting and tax matters [1], but even a qualified general accountant may not apply it correctly without dental-specific experience. The BDA also offers tax guidance for dentists [2], but members need to know what to ask for.
As Nathan Poole, who has worked with dentists for more than 15 years, said: "The first year as an associate dentist in practice isn't easy. You must start paying back your student loan, submit your first tax return and decide what kind of business structure will suit you." [3] A specialist accountant guides you through these decisions from the start, building a relationship that lasts. Linda Giles, a specialist dental accountant with nearly 30 years of experience, noted that "all the clients who started out with me stayed with me. It's a relationship of great trust." [3]
If you are an associate, practice owner, or locum dentist, the choice of accountant affects your tax bill, your pension planning, and your practice sale proceeds. A specialist accountant for dentists understands the specific rules that apply to your situation. General accountants are good for general businesses. Dentistry is not a general business.
Speak to a dental-specialist accountant to review your current tax position and ensure you are not missing reliefs that a general accountant may have overlooked. The cost of the specialist advice is usually far less than the tax savings it generates.
