Incorporation & Company Structures for Medical Practices

More GP practices and medical professionals are exploring incorporation as a way to reduce their tax burden and create a more flexible business structure. However, incorporating a medical practice involves far more than forming a company — from NHS contract considerations and CQC registration to pension implications and partnership buy-outs, the decision requires careful analysis. This hub covers everything you need to evaluate before making the move.

When to Consider Incorporating a Medical Practice

Incorporation tends to become attractive when practice profits significantly exceed the partners' personal income needs. If a GP practice generates substantial surplus that is reinvested or retained, the corporation tax rate of 25% (for profits above £250,000) or the small-profits rate of 19% can be materially lower than the 45% additional rate of income tax plus Class 4 National Insurance that partners would otherwise pay. The gap widens further where profits can be extracted as dividends rather than salary, taking advantage of lower dividend tax rates.

That said, incorporation is not a universal solution. Practices with profits that are fully drawn by partners each year see less benefit, because the tax saving on corporation tax is offset by the tax on extracting those profits. Practices planning to wind down, or where partners are close to retirement, may also find the costs and disruption outweigh the gains. A detailed projection comparing the after-tax position as a partnership versus a limited company or LLP over at least a five-year horizon is essential before committing.

Limited Company vs LLP Structures

The two main vehicles for incorporation are a private limited company and a limited liability partnership (LLP). A limited company is a separate legal entity that pays corporation tax on its profits; directors and shareholders then pay income tax on salaries and dividends drawn from the company. This creates the classic “two-tier” tax structure that can reduce the overall rate when profits are retained.

An LLP, by contrast, is tax-transparent — profits are allocated to members and taxed as self-employment income, much like a traditional partnership. The primary advantage of an LLP is limited liability protection without the corporation-tax layer, making it suitable for practices where all profits are distributed. LLPs also avoid the benefit- in-kind complications that arise when a company provides assets to directors. The right choice depends on the practice's profit level, distribution policy and long-term growth plans.

Tax Implications of Incorporation

Beyond headline tax rates, incorporation triggers several one-off and ongoing tax events. Transferring the practice's assets to a company may be treated as a disposal for capital gains tax purposes, though Section 162 incorporation relief can defer the gain where the entire business (including goodwill) is transferred in exchange for shares. HMRC scrutinises medical-practice goodwill valuations closely, so a robust, defensible valuation is essential.

Ongoing, the company must operate PAYE for director salaries, file annual accounts and a corporation tax return, and manage dividend paperwork. National Insurance treatment also changes: directors pay Class 1 NICs on salary rather than Classes 2 and 4, and the company pays employer NICs on top. Careful salary-and-dividend planning each year can optimise the overall position, but it requires ongoing professional advice as thresholds and rates change with each Budget.

Regulatory Considerations: CQC and NHS Contracts

Medical practices operating under an NHS GMS or PMS contract must obtain consent from NHS England (or the relevant ICB) before changing their legal structure. The contract itself cannot simply be assigned to a new entity — a fresh contract or novation agreement is required. CQC registration must also transfer to the new legal entity, which involves a fresh application, an assessment of the new registered manager and potentially an inspection.

These regulatory steps add both cost and timeline to the incorporation process. Practices should allow at least six to twelve months from the initial decision to the completion of the transfer. Engaging early with the ICB and CQC, and ensuring that the new entity's governance structure meets their requirements, reduces the risk of delays. Specialist medical accountants coordinate with solicitors and regulatory bodies to manage the process end to end.

The Transition Process and Costs

A typical incorporation involves several workstreams running in parallel: company formation and shareholder agreement drafting, goodwill and asset valuations, NHS contract novation, CQC re-registration, TUPE consultation for employed staff, bank account setup and finance restructuring, and pension scheme adjustments. Legal, accounting and valuation fees for a mid-sized GP practice commonly range from £15,000 to £30,000, depending on complexity.

Partners should also plan for the cash-flow impact. The company will need working capital from day one, and there may be a period where partners' drawings reduce while the company builds reserves. Stamp duty land tax may apply if property is transferred to the company, though holdover relief or SDLT group relief may be available in certain structures. A phased approach — incorporating the trading activity first and dealing with property separately — can sometimes smooth the transition.
