MTD for Income Tax: What Dental Associates Need to Know About the New Deadlines

If you’re a dental associate working on a self-employed basis, Making Tax Digital for Income Tax (MTD for IT) has changed how — and how often — you report to HMRC. Since April 2026, self-employed individuals and landlords with qualifying income above £50,000 must keep digital records and submit quarterly updates through HMRC-approved software, rather than filing a single annual return. The threshold drops to £30,000 from April 2027 and £20,000 from April 2028, bringing many more dental associates into scope.

Key Deadlines to Remember

Quarterly updates are due one month after each quarter ends: 7 August, 7 November, 7 February and 7 May. At the end of the tax year, you’ll still need to submit a final declaration confirming your total income and any adjustments, due by 31 January. Miss these dates and HMRC’s new points-based penalty system kicks in — repeated late submissions or payments can quickly add up to fines.

Why Timely Filing Matters

For dental associates, income can involve NHS and private earnings, expenses, pension contributions and superannuation — all of which need accurate, up-to-date digital records. Falling behind on quarterly submissions doesn’t just risk penalties; it also means losing sight of your real-time tax position, making it harder to plan for tax bills or investment decisions throughout the year.
