Dentists in the UK face complex tax rules. Your structure, income mix, and expenses all affect how much tax you pay. Without proper planning, you risk overpaying tax or facing HMRC issues.
This guide explains how tax works for dentists and how you can manage it effectively.
Your tax depends on how you operate.
If you work as an associate:
• You pay Income Tax on profits
• You pay Class 2 and Class 4 National Insurance
• You submit a Self Assessment tax return
Typical issue:
Many dentists do not track expenses properly and overpay tax.
If you run a dental practice through a company:
• The company pays Corporation Tax
• You take salary and dividends
• You pay personal tax on dividends
Key benefit:
You can plan tax efficiently using salary and dividend mix.
Most dentists have mixed income.
NHS income:
• Paid under contract
• More structured
Private income:
• Higher margin
• More planning opportunities
You must separate both clearly in your accounts.
Avoid these errors:
• Mixing personal and business expenses
• Missing allowable expenses
• Incorrect VAT treatment
• Poor record keeping
• Late tax returns
These mistakes lead to higher tax and penalties.
You can reduce your tax bill by claiming valid expenses.
Common allowable expenses:
• Dental materials and lab fees
• Equipment and instruments
• Professional indemnity insurance
• GDC registration fees
• CPD and training costs
• Accountancy fees
• Uniform and protective clothing
• Use of home or clinic costs
Proper tracking of these can significantly reduce your tax.
VAT rules are important.
• Most dental treatments are VAT exempt
• Cosmetic treatments may be VAT standard rated
• Mixed services require correct VAT treatment
Mistakes in VAT can trigger HMRC investigations.
Dentists benefit from pension planning.
• Contributions reduce taxable income
• Helps long-term financial planning
• Important for high earners
Proper planning avoids unexpected tax charges.
To reduce your tax legally:
• Choose the right business structure
• Plan salary and dividends
• Claim all allowable expenses
• Use pension contributions
• Keep accurate records
• Plan ahead for tax payments
Early planning gives better results.
Consider a limited company if:
• Your profits are increasing
• You want better tax efficiency
• You plan to grow your practice
• You want liability protection
This decision must be based on your income level and future plans.
From April 2026:
• Self-employed dentists earning over £50,000 must follow MTD rules

You must prepare now to avoid penalties.
