Making Tax Digital for Income Tax is rolling out in three confirmed phases, each with a lower income threshold than the last. By April 2028, more than two million UK sole traders and landlords will be required to comply. This guide breaks down exactly what each threshold means, who it applies to, and when.
Phase 1 began on 6 April 2026. If your combined self-employment and UK property rental income exceeded £50,000 in the 2024–25 tax year, you are mandatory now. Your first quarterly submission deadline is 7 August 2026 (Q1, covering 6 April – 5 July 2026).
This is the largest single group affected — roughly 700,000 sole traders and landlords, including most full-time self-employed people and landlords with substantial portfolios.
Phase 2 begins on 6 April 2027. If your combined self-employment and UK property rental income is between £30,000 and £50,000 in the 2025–26 tax year, you will become mandatory at this point — roughly 500,000 additional taxpayers.
If you are in this band now, you have time to prepare but should not be complacent — 2025–26 (the tax year running 6 April 2025 to 5 April 2026) is the year that determines your Phase 2 status, and that year has already begun.
Phase 3 begins on 6 April 2028 and was confirmed in the Spring Statement of 26 March 2025. If your combined self-employment and UK property rental income is between £20,000 and £30,000 in the 2026–27 tax year, you will become mandatory — bringing in the largest group yet, around 900,000 additional taxpayers.
This is the lowest threshold confirmed to date. There is currently no announced threshold or date for taxpayers below £20,000.
| Phase | Start Date | Threshold | Assessed Tax Year | First Q1 Deadline | Est. Taxpayers |
|---|---|---|---|---|---|
| Phase 1 | 6 April 2026 | Over £50,000 | 2024–25 | 7 August 2026 | ~700,000 |
| Phase 2 | 6 April 2027 | Over £30,000 | 2025–26 | 7 August 2027 | ~500,000 |
| Phase 3 | 6 April 2028 | Over £20,000 | 2026–27 | 7 August 2028 | ~900,000 |
Your MTD phase is based on your qualifying income in a specific prior tax year — not your current income, and not a future projection. This is important: you cannot simply look at this year's income to know your phase.
| If your income in... | Was... | You join MTD on... |
|---|---|---|
| 2024–25 | Over £50,000 | 6 April 2026 (now) |
| 2025–26 | £30,000 – £50,000 | 6 April 2027 |
| 2026–27 | £20,000 – £30,000 | 6 April 2028 |
Income naturally fluctuates year to year. Here is how the thresholds interact with changing income:
As of June 2026, there is no confirmed Phase 4 and no announced threshold below £20,000. The Spring Statement of 26 March 2025 confirmed Phase 3 (£20,000, April 2028) as the lowest threshold to date. Whether MTD will eventually extend to all sole traders and landlords regardless of income — similar to how MTD for VAT eventually became universal for VAT-registered businesses — remains unconfirmed. Monitor GOV.UK for future announcements, particularly around Budget and Spring Statement dates.
