Dentistry Is Not a Standard Business

Running a dental practice in the UK means dealing with a mix of NHS contract income, private patient fees, associate agreements, and partnership structures. A general accountant who handles a local shop or a building contractor will not know the specific rules that apply to dentists.

Specialist dental accountants understand how HMRC treats NHS contract income differently from private fees. They know the VAT partial exemption calculations that apply when you provide both exempt and taxable supplies. And they can structure your practice so you pay the right amount of tax, not more than you need to.

If you are a dentist operating through a limited company, a partnership, or as a sole trader, the wrong advice can cost you thousands. Let us look at the specific areas where specialist knowledge matters most.

NHS Contract Income and Corporation Tax

Most dental practices in the UK hold an NHS contract. The income from that contract is taxable, but how you account for it depends on your business structure.

If you trade as a limited company, your NHS contract income is part of your company's turnover. You pay corporation tax on the profit after deducting allowable expenses. The current corporation tax rates for 2025/26 are 19% on profits up to £50,000, 25% on profits above £250,000, and marginal relief in between.

A specialist dental accountant will help you time your equipment purchases, pension contributions, and staff costs to keep your profits in the lower tax band where possible. They will also know that NHS contract income is not subject to VAT, which affects how you handle your VAT returns if you also do private work.

Private Practice Income and VAT

Private dental work is generally exempt from VAT. But if you also sell goods like whitening kits, mouthguards, or electric toothbrushes, those sales are standard-rated for VAT.

Once your total taxable turnover (including standard-rated sales of goods) exceeds £90,000 in a rolling 12-month period, you must register for VAT. At that point, you need to apportion your input VAT between exempt and taxable supplies. This is called partial exemption.

Specialist dental accountants handle partial exemption calculations regularly. A general accountant might miss the nuance and either overclaim VAT (risking a penalty) or underclaim it (losing money).

If your practice is VAT-registered, you also need to consider the Flat Rate Scheme. Most dental practices fall under the 14.5% flat rate for "publishing" or the 11% rate for "management consultancy", depending on your exact activities. But if you are a limited cost trader (spending less than 2% of turnover on relevant goods), you must use 16.5%. A specialist will know which rate applies to your specific practice.

Associate Dentists vs. Partners vs. Practice Owners

The way you work determines your tax position. There are three common structures for UK dentists.

Associate Dentists

Most associates are treated as self-employed for tax purposes. They work under a contract for services, not a contract of employment. This means they pay their own tax through self assessment, claim their own expenses, and do not receive employee benefits like holiday pay or sick pay.

HMRC has challenged associate status in recent years. If your working arrangements look more like employment (fixed hours, set rotas, no risk of loss), HMRC may argue you are actually an employee. A specialist dental accountant will help you structure your associate agreement to reduce that risk.

Partners

If you are a partner in a dental practice, you file a partnership tax return (SA800) each year. Your share of the profit is taxed as your personal income. You pay Class 2 and Class 4 National Insurance on your profits, and you can claim certain expenses that employees cannot.

Partnerships also need to register with HMRC and file annual accounts. A specialist accountant will ensure the partnership agreement reflects the profit-sharing arrangement and that each partner's capital account is correctly maintained.

Practice Owners (Limited Company Directors)

If you own your practice through a limited company, you are both a director and a shareholder. You pay yourself a combination of salary and dividends. The most tax-efficient approach for 2025/26 is typically a salary of £12,570 (matching the personal allowance and primary NI threshold) and dividends up to the basic rate band.

Your company pays corporation tax on its profits. You can claim capital allowances on equipment, the Annual Investment Allowance (AIA) of up to £1,000,000 per year, and full expensing on most main-rate plant and machinery.

Pension Contributions for Dentists

Dentists in the NHS Pension Scheme face specific challenges. The annual allowance is £60,000 for 2025/26, but if your total income (including pension growth) exceeds £260,000, your annual allowance tapers down to a minimum of £10,000.

NHS pension growth is calculated using a complex formula based on your pensionable earnings and the scheme's accrual rate. Many dentists trigger the annual allowance charge without realising it. A specialist dental accountant will calculate your pension input amount and advise whether you need to use scheme pays or pay the charge from your own funds.

If you have a private pension alongside your NHS pension, the combined growth across both schemes counts towards your annual allowance. Getting this wrong means an unexpected tax bill.

Expenses You Can Claim as a Dentist

Dentists can claim a wide range of allowable expenses, but the rules differ depending on your structure. Common deductible expenses include:

  • Professional indemnity insurance
  • GDC registration fees
  • CPD courses and conference attendance
  • Practice consumables (gloves, masks, materials)
  • Equipment lease payments
  • Staff salaries and employer NI
  • Rent and business rates for the practice premises
  • Utilities and cleaning
  • Marketing and website costs
  • Accountancy fees

If you work from home for administrative tasks, you can claim a proportion of your household bills using HMRC's simplified expenses or actual costs. A specialist accountant will help you calculate the correct amount without triggering a benefit in kind.

Why General Accountants Often Get It Wrong

General accountants see a wide range of clients across different sectors. They know the basics of corporation tax, VAT, and self assessment. But they do not know the specific rules that apply to dental practices.

Common mistakes we see include:

  • Treating all associate income as employment income and deducting PAYE incorrectly
  • Failing to register for VAT when private goods sales cross the threshold
  • Missing the partial exemption calculation on mixed NHS/private practices
  • Not claiming capital allowances on dental equipment correctly
  • Ignoring the NHS pension annual allowance taper
  • Using the wrong Flat Rate VAT percentage

Each of these mistakes can cost you thousands in overpaid tax or HMRC penalties. A specialist dental accountant will catch them before they become a problem.

What to Look for in a Specialist Dental Accountant

Not every accountant who says they work with dentists is truly a specialist. Here is what to check:

  • Do they hold ICAEW or ACCA qualification? This is a baseline for competence.
  • Do they have current clients who are dentists? Ask for examples of practices they work with.
  • Do they understand NHS contract income and the pension scheme? If they cannot explain the annual allowance taper, they are not a specialist.
  • Do they handle VAT partial exemption for dental practices? This is a niche area that most general accountants avoid.
  • Do they offer year-round advice, not just year-end compliance? Dentistry involves ongoing decisions about equipment purchases, staff hiring, and practice expansion.

At Holloway Davies, our ICAEW qualified team works with dental practices across the UK. We understand the specific tax and compliance challenges you face. Our services cover everything from corporation tax and VAT to pension planning and practice incorporation.

Should You Incorporate Your Dental Practice?

Many dentists ask whether they should operate through a limited company rather than as a sole trader or partnership. The answer depends on your profit level, your NHS contract, and your long-term plans.

Incorporation can save tax if your profits are consistently above £50,000. The company pays 19% to 25% corporation tax on retained profits, rather than you paying 40% or 45% income tax on the same amount. But you also need to consider the cost of running a limited company: annual accounts, confirmation statements, payroll, and potentially higher accountancy fees.

If you are an associate dentist, incorporation is usually not worthwhile unless you have significant private income. Associates are already taxed as self-employed, and the additional compliance costs of a limited company often outweigh the tax savings.

For practice owners, incorporation can be a good move, but you need to plan the transfer carefully. Transferring an NHS contract to a limited company requires NHS England approval. You also need to consider the capital gains tax implications of transferring goodwill and equipment into the company.

Making Tax Digital for Income Tax Self Assessment (MTD for ITSA)

From April 2026, self-employed dentists and landlords with qualifying income over £50,000 must follow Making Tax Digital rules. This means keeping digital records and submitting quarterly updates to HMRC using compatible software.

From April 2027, the threshold drops to £30,000. From April 2028, it drops to £20,000. Most dentists will be affected within the next few years.

If you are not already using accounting software like Xero, FreeAgent, or QuickBooks, now is the time to start. A specialist dental accountant will help you set up your software correctly and ensure your quarterly submissions are accurate.

We cover MTD requirements in more detail on our VAT and Making Tax Digital blog.

Final Thoughts

Dentistry is a rewarding profession, but the tax and compliance side is complex. NHS contracts, private income, associate structures, pension rules, and VAT partial exemption all require specialist knowledge.

A general accountant may save you a few hundred pounds in fees each year. But the wrong advice can cost you thousands in overpaid tax, missed reliefs, or HMRC penalties. Specialist dental accountants pay for themselves many times over.

If your practice turnover crossed the VAT threshold in the last 30 days, register inside the 30-day window. If you are considering incorporation, speak to a specialist before you transfer any assets. And if you are unsure whether your current accountant is giving you the right advice, ask them the questions in this article.
