Why Making Tax Digital (MTD) for Income Tax Matters
Beginning 6 April 2026, certain UK taxpayers with self-employment or property income over £50,000 gross must comply with MTD for Income Tax. Under these rules you must:
- keep digital records of income and expenses using compatible software;
- send quarterly summary updates to HMRC;
- file an annual Self Assessment tax return. (gov.uk)
Failure to comply can lead to penalties including penalty points, particularly from the 2027-28 tax year where late quarterly updates or tax returns will carry penalty points. (gov.uk)
Practical Steps to Stay Compliant
| Task | Deadline or When Needed | What to Do |
|---|---|---|
| Determine if you qualify | Check gross turnover from self-employment + property income | If over £50,000, you must use MTD for IT from 6 April 2026. (gov.uk) |
| Choose software | Before your first update (next deadline after April 2026) | Use HMRC-approved software; ensure it can handle expenses, income coding, and bulk uploads if many income sources. |
| Register for MTD | Before first required quarterly update | Sign up via HMRC online services or agent; include all relevant self-employed or property income sources. (gov.uk) |
| Submit quarterly updates | 7 August 2026; 7 Nov 2026; 7 Feb 2027; 7 May 2027 | Use software to summarise records; even if income stopped, include the ceased portion in first update and last if ceasing. (gov.uk) |
| Watch for HMRC communication | From Sept 2026 onwards | HMRC will send letters to those who qualify but haven't signed up, possibly signing you up on your behalf if we find your 2024-25 turnover qualifies. (gov.uk) |
Example: Jill the Landlord
Jill rents out two properties and also does freelance graphic design. Her combined turnover from rent + self-employment in 2024-25 was £55,000. She must use digital software, send joint quarterly updates from both income sources, report expenses properly, and file her Self Assessment return as usual. If she misses a quarterly update deadline in the 2026-27 year, she will get a penalty point. She should have chosen software before her first update due 7 August 2026. |
Actionable Advice to Make It Easier
- Start early: even if turnover is just under threshold—understanding the process is useful as thresholds are reviewed.
- Organise records by income source and expense category; use tools that integrate bank feeds to reduce manual entry.
- Engage a tax agent if you’re unsure status of income sources or how to claim expenses properly.
- Don’t ignore communications from HMRC—they’ll warn you, but assuming they won’t enforce penalties is risky.
How This Impacts Your Tax Planning
- Digital record-keeping allows more accurate forecasting and cashflow planning.
- Splitting income and expenses cleanly can prevent disputes or misunderstandings with HMRC.
- If expenses from property income or self-employment are high, a proactive review could identify additional reliefs (e.g. capital allowances, mortgage-related reliefs) that reduce taxable profit.
Bottom line: for anyone with self-employment or property income over £50,000, MTD for Income Tax is now the norm. Get organised, choose good software, and mark those quarterly dates—it’s not just compliance, it’s modernising how we do tax in the UK.
