The three thresholds
Making Tax Digital for Income Tax is being phased in by income:
- Over £50,000: from 6 April 2026, based on your 2024/25 return.
- Over £30,000: from 6 April 2027, based on your 2025/26 return.
- Over £20,000: from 6 April 2028, based on your 2026/27 return.
It's turnover, not profit. A plumber with £35,000 of sales and £15,000 of costs has £35,000 of qualifying income, so they're in from April 2027.
Worked example
Alex has £28,000 of freelance turnover and £9,000 of gross rent from a flat. Qualifying income is £37,000. That's under £50,000 but over £30,000, so if Alex's 2025/26 return shows the same figures, MTD applies from 6 April 2027.
What changes for you
You'll need software that connects to HMRC, quarterly updates (due by the 7th of the month after each quarter ends), and a final declaration by 31 January. Penalties for late submissions move to a points system. Read the full MTD guide.
