# Orthodontic Practice Tax and Accounts: What Every Principal Needs to Know Publisher: Virtual Consultant Online Author: Virtual Consultant Online Published: 2026-08-15 Updated: 0001-01-01 Canonical URL: https://virtualconsultant.online/blog/orthodontic-practice-tax-accounts Citation metadata: https://virtualconsultant.online/citation.json?url=https%3A%2F%2Fvirtualconsultant.online%2Fblog%2Forthodontic-practice-tax-accounts Running an orthodontic practice as a business principal involves tax and accounting decisions that most clinical training does not prepare you for. The structure of your practice — sole trader, partnership, limited company, or a combination — has significant implications for how much tax you pay, how you extract income, how you plan for retirement, and how attractive your practice is to a buyer when you eventually sell. Getting these decisions right — or at least getting specialist advice early enough — can make a material difference to your net income and long-term financial position. This guide provides an overview of the key tax and accounting considerations for UK orthodontic practice principals — not as a substitute for specialist advice, but as a foundation for understanding what questions to ask your accountant and why the answers matter. Key takeaway The single most impactful financial decision most UK orthodontic principals can make is to engage a NASDAL-registered dental specialist accountant rather than a general practice accountant. The tax planning opportunities available to dental and orthodontic principals — practice structure, income extraction mix, capital allowances, pension contributions, and practice sale treatment — are numerous and often mishandled by accountants without sector-specific experience. The cost of specialist accountancy is typically recovered many times over in tax efficiencies and avoided mistakes. If you are currently with a general accountant and have not reviewed your structure in the past three years, a specialist review is strongly recommended. ## Practice Structure: Sole Trader vs Limited Company The structure through which you operate your orthodontic practice has significant tax implications. The two most common structures for UK orthodontic principals are: Sole trader / partnership Profits taxed as personal income via Self Assessment Simpler accounting and administration Class 4 National Insurance applies to profits Losses can be offset against other income Generally less tax-efficient at higher profit levels Limited company (incorporated) Corporation tax on company profits (25% from April 2023 for profits above £250k) Director/shareholder extracts income via salary + dividends Potentially tax-efficient for higher-earning practices More complex accounting, compliance costs May enable Business Asset Disposal Relief on sale The “right” structure depends on your profit level, your income extraction preferences, your retirement planning, and whether you intend to sell the practice — and should be reviewed with a dental specialist accountant who understands all of these factors in combination. The tax efficiency of incorporation has reduced significantly since the corporation tax increase to 25% in April 2023, making the structure decision less clear-cut than it was for many years. ## Income Extraction: Salary, Dividends, and Pension For principals operating through a limited company, the mix of income taken as salary, dividends, and employer pension contributions is a key annual tax planning exercise. Optimal salary: most dental company directors pay themselves a salary at the National Insurance secondary threshold (approximately £9,100 for 2026/27), which avoids both employee and employer NI while preserving entitlement to the state pension. Income above this is more efficiently taken as dividends. Dividends: taxed at 8.75% (basic rate) and 33.75% (higher rate) for 2026/27, after the £500 dividend allowance. Dividends do not attract National Insurance contributions, making them more tax-efficient than additional salary at the same income level for most principals. Employer pension contributions: company pension contributions are a corporation tax deduction and do not attract NI. For principals who need to build retirement savings, employer pension contributions are typically the most tax-efficient use of company profits after income requirements are met — they reduce the corporation tax bill while building the pension pot.

See how it works → ## VAT: The Dental Practice Exemption Most orthodontic treatment provided by a GDC-registered specialist qualifies as a VAT-exempt healthcare service under the UK VAT Act 1994. This means orthodontic treatment fees are not subject to VAT — but it also means the practice cannot reclaim VAT on its purchases and overheads (as a business making exempt supplies). The key exception is any non-clinical activity the practice undertakes that does not qualify as healthcare — for example, sale of ancillary products, cosmetic procedures where the primary purpose is aesthetic rather than healthcare, or income from lectures and teaching. These activities may be taxable and require careful VAT treatment to avoid unexpected liabilities. If your practice has mixed VAT status (exempt and taxable supplies), the VAT treatment can become complex and specialist advice is essential. ## Capital Allowances and Equipment Orthodontic equipment purchases — treatment chairs, CBCT scanners, intraoral scanners, digital imaging systems — qualify for capital allowances, which reduce the practice’s taxable profits. For most small and medium practices, the Annual Investment Allowance (AIA) allows 100% of qualifying equipment expenditure to be deducted in the year of purchase, up to the AIA limit (currently £1 million per year). This makes the timing of major equipment purchases a tax planning consideration — purchasing equipment before the year end rather than after can accelerate the tax relief significantly. Important This guide provides a general overview of the tax and accounting landscape for UK orthodontic principals — it is not tax advice, and it cannot account for your individual circumstances, practice structure, income level, or retirement position. Tax rules change regularly; what was optimal three years ago may not be optimal today. Engage a NASDAL-registered dental specialist accountant for advice specific to your practice — they will be familiar with the dental sector-specific tax issues (goodwill treatment, NHS pension interaction, associate status, practice sale tax planning) that a general accountant is unlikely to handle with the same depth of knowledge. HMRC provides guidance on self-assessment, capital allowances, and VAT exemptions on its website, but sector-specific planning requires sector-specific expertise.

The optimal structure for a UK orthodontic practice depends on profit level, income requirements, retirement planning, and sale intentions — and should be reviewed with a NASDAL-registered dental specialist accountant. As a general guide: at profit levels below approximately £50,000 to £70,000, the simplicity of sole trader status often outweighs the tax efficiency of incorporation; at higher profit levels, the ability to retain profits in the company at the 25% corporation tax rate and extract them as dividends can be more efficient. The increase in corporation tax to 25% in April 2023 reduced the benefit of incorporation for many principals, and some have since disincorporated. Review your structure at least every three years. ### Is orthodontic treatment VAT-exempt in the UK? Yes — orthodontic treatment provided by a GDC-registered practitioner qualifies as an exempt healthcare service under the UK VAT Act 1994, meaning treatment fees are not subject to VAT. The downside of VAT exemption is that the practice cannot reclaim input VAT on its purchases and overheads (since it is not making taxable supplies). Any non-clinical income the practice generates — ancillary product sales, purely cosmetic procedures where healthcare is not the primary purpose — may be subject to VAT and require careful treatment to avoid unexpected liabilities. ### Can an orthodontic practice claim capital allowances on equipment? Yes — orthodontic equipment purchases qualify for capital allowances under the Annual Investment Allowance, which allows 100% of qualifying capital expenditure to be deducted against taxable profits in the year of purchase, up to the current AIA limit of £1 million per year. This makes the timing of major equipment purchases a tax planning consideration — purchasing a CBCT scanner or intraoral scanner before the practice’s tax year end rather than after can accelerate the tax relief by up to 12 months. Leased equipment is treated differently from purchased equipment for capital allowances purposes — take specific advice on the tax treatment before making major equipment acquisition decisions. ### What tax is payable when selling an orthodontic practice? The tax payable on an orthodontic practice sale depends on the sale structure (share sale versus asset sale), the seller’s individual tax position, and whether Business Asset Disposal Relief (BADR) — formerly Entrepreneurs’ Relief — applies. BADR reduces Capital Gains Tax to 10% on the first £1 million of qualifying gains from the sale of a business asset, subject to conditions. For a share sale of a qualifying trading company, BADR is typically available and can represent a very significant tax saving. Asset sales are taxed differently and the BADR position is more complex. The tax treatment of goodwill on an asset sale has changed significantly in recent years. Take specialist legal and tax advice from a NASDAL-registered adviser before entering any sale process — the structure chosen at the start of the transaction significantly affects the final net-of-tax proceeds. ### Should an orthodontic practice operate as a sole trader or limited company?
