MTD vs Self Assessment 2026-27: Who Is Affected?

Not tax advice. Information only. Check GOV.UK or a qualified adviser for your own situation. Dates and rules were last checked against GOV.UK on 17 October 2026 and can change.

Short answer: Making Tax Digital (MTD) for Income Tax doesn't remove your 2025 to 2026 Self Assessment return. GOV.UK says you still need to submit a Self Assessment return for the tax year before you start using MTD for Income Tax.

Who has to use MTD, and when (GOV.UK)

Qualifying income in the year Threshold MTD from
2024 to 2025 more than £50,000 6 April 2026
2025 to 2026 more than £30,000 6 April 2027
2026 to 2027 more than £20,000 6 April 2028

Qualifying income is gross self-employment and property income before expenses. Employment income, dividends and pensions don't count. See our MTD guide (separate section).

What changes in 2026-27 if you're already in MTD

What to do now

  1. Work out whether MTD applies to you (GOV.UK's tool).
  2. File your 2025-26 return by 31 January 2027.
  3. If MTD applies, choose compatible software.

FAQ

I earn £35,000 from self-employment: do I need MTD in April 2027? On the figures above, qualifying income over £30,000 for 2025 to 2026 means MTD from 6 April 2027; HMRC assesses it from your return.

Is MTD software the same as filing software? Not necessarily; see GOV.UK's software page.
