Choosing the right business structure for your dental practice

Introduction

When it comes to owning and running a dental practice, choosing the right business structure is about more than administration. It shapes how your income is taxed, how risk is managed, and ultimately how financially secure your career can become over the long term.

In 2026, the decision between operating as a sole trader, a limited company or a partnership is increasingly complex. Changes to tax reporting and regulatory requirements mean that what worked a decade ago may not necessarily be the most suitable option today.

Here we explore how each structure compares, focusing on financial security, tax efficiency and long-term planning for dentists.

Why is business structure important?

Your business structure is important because it determines:

• How your profits are taxed
• Your exposure to legal and financial risk
• How easily you can grow or restructure your practice
• Your ability to retain profits or extract income tax-efficiently

In dentistry (where income can vary significantly between NHS, private and mixed practice work), these factors can have a real impact on wealth building and retirement planning.

Sole trader

For many dental professionals, the sole trader model is often the default starting point. Operating as a sole trader means you and the business are legally the same entity. Income is reported through Self Assessment and taxed as personal income.

Some advantages include:

• Administrative simplicity

In comparison to incorporated businesses, sole traders typically face fewer reporting requirements and lower accounting costs.

• Straightforward tax

All profits are taxed as personal income through the UK income tax system, making the structure easy to understand and manage.

• Ideal for early-career dentists

For those earning moderate incomes or starting out as associates, the simplicity can outweigh tax disadvantages.

Some disadvantages include:

• Unlimited liability

The key risk is that there is no separation between personal and business finances. If the business incurs debt or legal claims, your personal assets could be exposed.

• Tax inefficiency at higher earnings

As income rises, profits are taxed through personal income tax bands, potentially reaching higher-rate or additional-rate tax levels.

• Less flexible tax planning

All profits are taxed in the year they are earned, even if the money remains within the business.

Limited company

For dentists with higher earnings or long-term growth ambitions, the limited company structure often becomes increasingly attractive. A limited company is a separate legal entity from its owner, which fundamentally changes how tax works and how liability is handled.

Some advantages include:

• Limited liability protection

Shareholders are generally only liable up to the value of their shares, helping protect personal assets.

• Potentially greater tax efficiency

Companies pay corporation tax on profits (currently between 19% and 25% depending on profit level) before funds are distributed to owners.

• More strategic tax planning

Directors can take income through a combination of salary and dividends, while pension contributions made through the limited company can help reduce taxable income. This provides more tax planning opportunities than a sole trader structure allows.

• Ability to retain profits

A company can keep profits within the business for reinvestment, helping create financial resilience and support practice growth.

• Improved credibility and scalability

Operating as a limited company may make it easier to secure funding, attract partners or eventually sell a practice.

Some disadvantages include:

• Administrative burden

Limited companies must file annual accounts, maintain statutory records and comply with Companies House reporting requirements.

• Additional accounting costs

Professional support is usually required to ensure tax efficiency and regulatory compliance.

• Two stages of tax

Profits are taxed at the corporate level and again when extracted personally (through dividends, for example).

It’s also worth noting that for dentists working within NHS structures, incorporation may affect eligibility for the NHS Pension Scheme, potentially impacting retirement planning and other important benefits or pension contributions.

With this in mind, professional advice should be sought before making any structural changes.

Partnership

Partnerships are common in dental practices where multiple clinicians are operating jointly. In a standard partnership, partners share both profits and liability, and each pay tax on their share through personal income tax.

Some advantages include:

• Shared financial responsibility

Costs, risks and investments are spread between partners.

• Combined expertise and resources

  Partnerships can support practice growth through shared skills, experience and resources.

• Straightforward tax treatment

Each partner simply declares their share of profits via Self Assessment.

Some disadvantages include:

• Shared liability

Partners can be personally responsible for debts or obligations created by another partner.

• Potential for disputes

Profit distribution, workload expectations and strategic decisions can become sources of conflict without a strong partnership agreement.

• Less tax flexibility than incorporation

Like sole traders, profits are taxed as personal income.

Which structure is best?

As with most financial decisions, there’s no single “best” option for every dentist. However, there are some general trends that may help guide your decision.

For example, sole trader arrangements often suit early-career associates or those who prioritise simplicity, while partnerships remain common for dentists sharing the responsibilities and rewards of running a practice.

Limited companies are increasingly attractive for higher-earning dentists and practice owners seeking greater tax planning flexibility and the ability to retain profits within the business.

Importantly, the right structure will often change throughout your career. You might start as a sole trader, move into ownership or a partnership, and later consider incorporation as your income grows and financial planning becomes more complex.

Remember, financial security isn’t just shaped by how much you earn, but by whether your business structure supports your long-term goals.
