Self Assessment Tax Returns for Associate Dentists

Who needs to file a Self Assessment tax return?

Many associate dentists must file a Self Assessment return: you need one if you have untaxed income such as private, locum or self-employed work. A high PAYE salary alone does not require Self Assessment for 2026/27; check HMRC's current criteria and any notice to file. The online filing and payment deadline is 31 January after the tax year ends. Under the non-MTD rules, late filing normally triggers an initial £100 penalty, with further penalties for longer delays. A different regime applies from the tax year you join MTD for Income Tax.

What documents do I need for my return?

You typically require P60s, P11D forms, interest certificates, and records of all business income and expenses. Medical.Accountants provides a tailored checklist based on your specific healthcare role. We will request these details during our onboarding process. Providing comprehensive documentation ensures your tax position is accurately calculated.

What are payments on account?

Payments on account are advance payments towards your next Self Assessment bill, normally due on 31 January and 31 July. Each is usually half the previous year’s relevant Income Tax and Class 4 National Insurance bill, excluding Capital Gains Tax and student loans. Exceptions apply where the bill is below £1,000 or over 80% was collected at source.

Can my accountant file for me?

Yes, a chartered accountant can act as your authorised agent to file returns with HMRC. Medical.Accountants manages the entire submission process once you have reviewed and approved the figures. We use secure software to ensure your data is handled safely. This service is included within our agreed fixed fees.

How are NHS pension charges reported on my return?

Most NHS doctors and many healthcare staff are members of the NHS Pension Scheme. Contributions are deducted through payroll, and locum or private work can count only through the correct forms. High earners should check the annual allowance each year, as pension growth can trigger a tax charge.

Can I amend a return after filing?

You can generally amend a Self Assessment return within 12 months of the 31 January filing deadline. This allows you to correct errors or include forgotten information. Medical.Accountants can assist in reviewing previous submissions to ensure accuracy. Tax refunds can be claimed for up to four previous tax years.

How much does an accountant charge for a tax return?

Our packages for associate dentists start at £45.83 + VAT a month, with Core at £62.50 and Growth at £75 + VAT. The right package depends on your income sources, whether you trade through a company and any payroll, VAT or pension work. We confirm the exact fee in writing before any work begins, so there are no surprise invoices.

Are associate dentists self-employed for tax?

Employment status depends on the real working relationship: who controls the work, whether you can send a substitute, whether you carry financial risk and how integrated you are. A contract label alone does not decide it. HMRC's Check Employment Status for Tax tool and case law set the tests, and getting it wrong can leave the engager owing PAYE.

How much tax does an associate dentist pay?

Associate dentists pay income tax on taxable profit at 20%, 40% and 45%, plus Class 4 National Insurance on self-employed profit. Payments on account mean your first bill can include half of next year's tax too. Where income also comes from overseas, residence status and split year treatment decide what the UK taxes.

Can associate dentists set up a limited company?

A limited company can suit associate dentists with substantial private or outside-IR35 income that is not all needed to live on, because profit is taxed at corporation tax rates and can be paid out over time. It brings extra accounts, payroll and filing costs, and NHS employment income cannot move into it. We model sole trader against limited company on your real figures first.

What records must I keep?

You must keep records of all sales, business expenses, bank statements, and relevant tax documents. Digital record-keeping is increasingly necessary to satisfy MTD requirements. Records should generally be retained for at least six years. Medical.Accountants advises you on the best methods to capture and store these documents efficiently.

How quickly can you catch up late returns?

Timing depends on the scope of the work, completeness of your records and any information needed from HMRC, NHS Pensions or your previous accountant. We confirm the documents required and agree a realistic timetable before starting. Onboarding is separate from completing the review or filing outstanding returns; neither has a guaranteed turnaround.

Am I owed a tax refund?

You may be owed a tax refund if you have overpaid tax through PAYE or Self Assessment. Common reasons include unclaimed professional expenses or changes in clinical income levels. Tax refunds can generally be claimed for the four previous tax years. We review your historical filings to identify any potential overpayments.
