What Is Making Tax Digital (MTD) for Income Tax?
Making Tax Digital for Income Tax is the UK government’s once-in-a-generation reform of Self-Assessment. From 6 April 2026, sole traders and landlords with qualifying income over £50,000 must keep digital records, use MTD-compatible software, and submit quarterly updates to HMRC.(gov.uk) Thresholds will fall: March 2027 for those with income over £30,000, then £20,000 in April 2028.(gov.uk)
Key Compliance Steps & Deadlines
- 6 April 2026: Qualifying income £50,000+ → mandatory MTD for Income Tax begins.(finistry.co.uk)
- April 2027: Income £30,000+ join. April 2028 → £20,000+ join.(gov.uk)
- No penalty points for late quarterly updates during first 12 months for new entrants.(finistry.co.uk)
What Counts as “Qualifying Income”?
Qualifying income includes gross income from self-employment and UK property before expenses. Shares of profit from partnerships are not included in that qualifying income threshold.(gov.uk)
Software & Record-keeping Requirements
- Keep digital records using MTD-compatible or bridging software. Even spreadsheets may work if using bridging tools.(moneyweek.com)
- If using an agent, ensure it is authorised and the software integration with HMRC is properly aligned.(gov.uk)
Penalties & Transitional Relief
- For first year in new penalty regime, you get leniency: occasional late quarterly submissions won’t bring immediate fines.(moneyweek.com)
- But after first year, penalties apply via a points system, triggering a fixed penalty once a set number is reached.(moneyweek.com)
Practical Example
Alice is a landlord with gross rental income £60,000/year and also works freelance earning £10,000. Combined qualifying income: £70,000. From April 2026 she must report quarterly updates under MTD; if she misses one, first year she won’t immediately be fined, but repeated failures will incur penalty points.
Bob in 2027, with £35,000 qualifying income, also falls in scope; he can use the extra time to pick software, streamline accounts, and practice before enforcement ramps up.
Tips to Stay Ahead
- Register now in voluntary testing programs to get familiar.(gov.uk)
- Separate personal and business banking accounts for clearer tracking.
- Use accounting software that supports bridging to HMRC open data formats.
- Engage a tax adviser early to avoid errors in first quarterly submissions.
Conclusion
MTD for Income Tax marks a major shift in UK compliance. For those in scope from April 2026, preparation now—software, records, and workflows—is essential to avoid penalties and gain efficiency.
