Should UK dentists go self-employed or form a limited company? Compare tax, pension & liability pros and cons with Leader Accountancy’s dental experts.
As a UK dentist, choosing between self-employment and operating through a limited company is one of the most significant financial decisions you’ll make. With recent changes to dividend tax rates, corporation tax, and NHS pension considerations, the landscape has become increasingly complex. This comprehensive guide will help you understand which structure offers the most advantages for your specific circumstances, whether you’re an NHS associate, private practitioner, or running your own practice.
How UK Dentists Are Paid: NHS vs Private Work
Before diving into business structures, it’s important to understand how dental professionals typically receive income in the UK.
NHS Dental Contracts
NHS dentists typically work as associates under a contract with a practice owner who holds an NHS contract. As an associate, you’re paid a percentage of the Units of Dental Activity (UDAs) you complete. This income is paid without tax deductions, as associates are considered self-employed contractors rather than employees.
A key consideration for NHS dentists is access to the NHS Pension Scheme, which is only available to self-employed practitioners performing NHS work, not to those operating through limited companies.
Private Dental Work
Private dental work operates differently, with dentists either charging fees directly to patients or working with private insurance schemes. Private dentists have more flexibility in their fee structures and can often command higher rates for specialized treatments.
For private work, dentists have greater freedom to choose their business structure without impacting pension benefits, making a limited company potentially more attractive for those focused primarily on private dentistry.
Self-Employed vs Limited Company: Key Differences for Dentists
The decision between self-employment and incorporation involves weighing several factors including tax rates, profit extraction methods, and personal liability.
| Factor | Self-Employed | Limited Company |
| Tax Rates | Income Tax (20-45%) + National Insurance contributions | Corporation Tax (25%) on profits + Personal Income Tax on salary/dividends |
| NHS Pension | Eligible to contribute | Not eligible |
| Profit Extraction | All profits taxed annually regardless of whether withdrawn | Flexible – can take salary, dividends, or retain profits in company |
| Personal Liability | Unlimited personal liability | Limited liability (personal assets protected) |
| Administrative Burden | Simpler accounts, annual Self Assessment | More complex – annual accounts, Corporation Tax Return, Confirmation Statement |
| Income Sharing | Cannot share income with spouse (unless partnership) | Can make spouse a shareholder to utilize their tax allowances |
Tax Implications for UK Dentists
The tax landscape for dental professionals has changed significantly in recent years, with increases in dividend tax rates and corporation tax making the decision more nuanced.
Self-Employed Tax Advantages
- Simpler accounting and lower accountancy costs
- Eligible for NHS pension scheme contributions
- Can use the cash accounting scheme
- Business details remain private (not published on Companies House)
- No separate company tax return required
Self-Employed Tax Disadvantages
- Higher tax rates on profits above £50,270 (40% income tax + NI)
- Must make payments on account (paying tax earlier)
- First tax payment includes 18 months of tax liability
- 62% effective tax rate on income between £100,000-£125,000
- Cannot share income with spouse to utilize their allowances
Limited Company Tax Advantages
- Lower initial tax rate on profits (25% corporation tax)
- Flexibility in profit extraction (salary, dividends, or retention)
- Can share income with spouse through dividends
- Tax-efficient equipment purchases with capital allowances
- Can keep personal income below £100,000 to retain personal allowance
Limited Company Tax Disadvantages
- Not eligible for NHS pension scheme

Special Considerations for NHS Dentists
NHS dentists face unique considerations when choosing their business structure, particularly regarding pension benefits and parental leave pay.
NHS Pension Scheme Impact
If you incorporate your dental business, you will become ineligible to contribute to the NHS Pension Scheme from the point you start trading through the company. This can represent a significant loss of benefits, especially for dentists with substantial NHS work.
Independent financial advice should be sought before making this decision, as the value of NHS pension benefits can be substantial over a career.
NHS Parental Leave Benefits
Many dentists are unaware that trading through a limited company also means losing NHS parental leave benefits. Self-employed NHS dentists are entitled to:
- 26 weeks of paid maternity leave for women (based on estimated net pensionable earnings)
- 2 weeks of paid paternity leave for men
For a female dentist with annual net pensionable earnings of £50,000, this could mean receiving £25,000 in maternity pay – a significant benefit that would be lost through incorporation.
Hybrid Approach for NHS Dentists
Some dentists with both NHS and private income opt for a hybrid approach:
- Remain self-employed for NHS work to maintain pension and parental leave benefits
- Establish a limited company for private work to benefit from tax efficiencies
While this creates some additional administrative complexity, it can provide the best of both worlds for dentists with mixed income sources.
Profit Thresholds: When Does a Limited Company Make Sense?
The decision to incorporate is heavily influenced by your profit level and how much income you need to extract from the business.
Minimum Profit Threshold
For most dental associates, a limited company typically becomes tax-advantageous when profits exceed approximately £50,270 (the higher rate tax threshold). Below this level, the tax savings may not justify the increased administrative costs.
The £100,000 Threshold Consideration
A particularly important threshold occurs at £100,000 of personal income. Above this level, self-employed dentists begin to lose their personal allowance at a rate of £1 for every £2 earned, creating an effective tax rate of up to 62% on income between £100,000 and £125,140.
A limited company can help manage this issue by allowing you to control your personal income level through strategic salary and dividend planning.
Income Extraction Requirements
The amount of profit you need to extract from your business is crucial in determining the optimal structure:
- High extraction needs: If you need to withdraw most or all profits for living expenses, the tax advantage of a company may be reduced
- Lower extraction needs: If you can leave profits in the company, the tax benefits increase substantially
- Spouse involvement: Having a spouse as a shareholder can significantly increase tax efficiency through income splitting
Case Example: Dentist with £120,000 Profit
A dentist earning £120,000 with personal expenses of £60,000 could save approximately £10,000-£15,000 in tax annually through a limited company structure by:
- Taking a small salary up to the National Insurance threshold
- Extracting dividends to meet living expenses
- Retaining remaining profits in the company
- Potentially involving a spouse as a shareholder to utilize their tax allowances
Transitioning from Self-Employed to Limited Company: Step-by-Step
If you’ve determined that a limited company structure would benefit your dental practice, here’s how to make the transition smoothly.
- Seek Professional Advice
Consult with an accountant specializing in dental practices to confirm that incorporation is right for your specific circumstances. - Check Practice Agreement
Review your associate agreement to ensure it allows you to provide services through a limited company. Some practices may require contract amendments. - Incorporate Your Company
Register your company with Companies House, choosing an appropriate name and appointing directors (typically yourself and potentially your spouse). - Set Up a Business Bank Account
Open a dedicated business account for your company to maintain clear separation between personal and business finances. - Register for Taxes
Register for Corporation Tax with HMRC and, if applicable, for VAT if your turnover exceeds the threshold. - Create New Contracts
Establish a contract between your company and the dental practice(s) where you work as an associate. - Implement Accounting Systems
Set up proper accounting systems to track income, expenses, and tax obligations. - Plan Salary and Dividend Strategy
Work with your accountant to determine the most tax-efficient combination of salary and dividends.
Important Timing Considerations
The timing of your transition can significantly impact your tax position. Many dentists find it beneficial to align the change with the start of a new tax year (April 6th) to simplify accounting and tax calculations.
If you have NHS work, carefully consider the pension implications before proceeding with incorporation.
Equipment Purchases and Practice Ownership Considerations
Your business structure affects how you purchase equipment and plan for practice ownership.
Equipment Purchases
Limited companies offer certain advantages for equipment purchases:
- Access to Annual Investment Allowance for immediate tax relief on equipment
- Option to lease equipment through the company with tax-deductible payments
- Potential for more favorable financing terms as a limited company
- Tax-efficient vehicle ownership, particularly for electric cars with significant BIK advantages
Practice Ownership Planning
If you’re considering purchasing a dental practice in the future, your business structure can impact your ability to save for a deposit and secure financing:
- Limited companies can retain profits taxed at 25% rather than higher personal tax rates
- Accumulated company funds can be used for practice deposits (typically 10-20% of purchase price)
- Company structure may offer more flexibility when structuring practice acquisition
- Some lenders view limited companies with strong balance sheets more favorably

FAQs for Dentists: Self-Employed vs Limited Company
Can a dentist operate both as self-employed and through a limited company?
Yes, dentists with both NHS and private income can operate under a hybrid model. You can remain self-employed for NHS work (maintaining NHS pension eligibility) while channeling private income through a limited company for tax efficiency. This approach requires careful accounting separation but can provide the benefits of both structures.
What are the tax advantages for dentists with limited companies?
The main tax advantages include:
- Lower initial tax rate on profits (25% corporation tax vs up to 45% income tax)
- Ability to control when and how much income you extract
- Option to involve spouse as a shareholder to utilize their tax allowances
- Avoiding the 62% effective tax rate on income between £100,000-£125,140
- Retaining profits in the company for future investment at lower tax rates
- More tax-efficient equipment purchases through capital allowances
Is it worth setting up a limited company for NHS dentists?
For dentists who primarily perform NHS work, the decision is more complex due to NHS pension considerations. A limited company structure means losing eligibility for the NHS Pension Scheme and NHS parental leave benefits. For many NHS dentists, these benefits outweigh potential tax savings from incorporation.
However, if you have significant private income alongside NHS work, a hybrid approach may be beneficial. Each situation requires individual assessment based on income levels, pension valuation, and personal circumstances.
Can a limited company own dental equipment and lease it back?
Yes, a limited company can purchase dental equipment and claim capital allowances against its profits. If you’re working as an associate in multiple practices, having your company own portable equipment can be tax-efficient.
Some dentists also explore arrangements where their company owns equipment used in a practice where they work, but this requires careful contractual arrangements and consideration of VAT implications. Professional advice should be sought before implementing such structures.

Making the Right Choice for Your Dental Career
The decision between self-employment and a limited company structure is highly individual and depends on your specific circumstances, income level, and future plans. While limited companies can offer significant tax advantages for many dentists, those with substantial NHS commitments need to carefully weigh the loss of pension benefits.
As tax rules continue to evolve, regular review of your business structure with a specialist dental accountant is essential to ensure you’re operating in the most tax-efficient manner possible.
