Orthodontic Practice Tax and Accounts: What Every Principal Needs to Know

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.

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.

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.

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.
