Incorporating a Dental Practice: Limited Company vs Partnership
Incorporating a dental practice changes the tax position, the personal liability exposure, and crucially the NHS pension access. The decision is consequential and the right structure depends on the long-term plan.
For UK dental practices, the structural choice between unincorporated (sole trader, partnership) and incorporated (limited company) is a substantial financial decision. Incorporation produces tax efficiency at scale, asset protection, and continuity through ownership transfer. It also has consequences for NHS pension access, NHS contract transfer mechanics, and the relationship with associates. The right decision depends on the long-term plan: continuing principal, succession planning, eventual sale, or specialty consulting through a PSC.
This guide covers the incorporation decision and the structural alternatives for UK dental practice. Each section links to a detailed companion piece.
NHS pension access ends with full incorporation
If a principal incorporates the practice and ceases to be NHS-superannuable in their personal capacity, NHS pension contributions stop. The pension benefits already accrued are preserved but no further accrual occurs. For principals close to retirement, this is a substantial cost that often outweighs the tax advantages of incorporation. For younger principals with decades to retirement, the cost matters less.
Tax comparison: partnership vs limited company
For a practice generating £200,000 of profit shared between two partners:
| Structure | Annual tax (per partner) | Effective rate |
|---|---|---|
| Partnership (each partner self-employed) | £35,000-£40,000 | ~35-40% |
| Limited company (each director-shareholder) | £25,000-£30,000 | ~25-30% |
The difference compounds across decades. A £10,000-£15,000 annual saving × 20 years of practice = £200,000-£300,000 of cumulative tax saving (in nominal terms). Plus the eventual sale through BADR at 14% CGT versus the partnership disposal at standard rates.
Transferring the NHS contract on incorporation
Transferring an NHS dental contract from an unincorporated practice to a newly-incorporated company requires NHS commissioning approval and is not automatic:
- Apply to NHS England (or the relevant ICB now) for variation of the contract to transfer to the new entity.
- New limited company must satisfy the contract criteria (sufficient dentists, premises, CQC registration).
- CQC registration must transfer in parallel (separate process).
- Complete the practice incorporation before the contract transfer is approved (timing matters).
- Maintain unbroken delivery of UDAs across the transition (any gap creates clawback exposure).
The transfer typically takes 3-9 months depending on commissioning workload and complexity. Specialist legal and accounting support is essential.
Personal Service Companies for specialists
Specialist dental consultants (orthodontists, oral surgeons, periodontists, prosthodontists) often operate through Personal Service Companies (PSCs) for hospital or referral work. The position:
- Hospital-based consulting work: typically inside IR35 if engaged through agency or NHS trust framework.
- Private referral work: usually outside IR35 if the consultant has multiple referring sources, controls treatment plans, and bears the financial risk.
- Private practice ownership combined with consulting: the consulting income flows through the practice company along with the practice trading.
- IR35 determination quality matters substantially given the income concentration typical of specialist consultancy.
Dividend vs salary strategies
For incorporated dental directors, the standard 2026 extraction pattern:
- Salary at £12,570 (personal allowance): uses allowance, generates qualifying NI year, minimal income tax.
- Pension contributions (employer): up to £60,000/year annual allowance, corporation tax deductible.
- Dividends: extract balance from post-tax profit at dividend rates (8.75% basic, 33.75% higher, 39.35% additional).
For high-earning principals (£200k+ extraction), substantial pension contributions early in the career compound advantageously over decades. Specialist modelling matters because the optimal split shifts with each year's tax thresholds.
Shareholder agreements for dental partners
Incorporated practices with two or more shareholders need a shareholder agreement covering: vesting of shares, departure scenarios (good leaver / bad leaver), dispute resolution, drag and tag rights on eventual sale, and specific NHS-contract continuity provisions. Standard partnership agreements need adaptation when moving to limited company; off-the-shelf templates rarely cover the dental specifics correctly.
