What is Making Tax Digital for Income Tax?
Making Tax Digital (MTD) for Income Tax is a major shift requiring sole traders and landlords with income from self-employment or property above certain thresholds to keep digital records and submit quarterly updates to HMRC using compatible software. The schedule is phased by income:
| Qualifying Income (from self-employment + property) | Start Date | Obligation |
|---|---|---|
| Over £50,000 (2024–25 tax year) | 6 April 2026 | Mandatory from this date (gov.uk) |
| Over £30,000 | 6 April 2027 | Next band with same obligations (gov.uk) |
| Over £20,000 | 6 April 2028 | Final band for phased rollout (gov.uk) |
Key Requirements
- Keep digital records of all income & expenses using compatible software.
- Use quarterly updates to report self-employment & property income (on a fixed schedule, e.g. 7th August, November, February & May) (gov.uk).
- At year‐end, submit your full Self Assessment return through the same system by 31 January.
Penalties & Exceptions
- A new points-based penalty regime applies for late submissions: initial slip-ups are less likely to incur penalties, but repeated misses accumulate penalty points. (gov.uk)
- Payment delays now incur penalties more proportionate to the amount and duration of late payment. (gov.uk)
- Exemptions exist for those who are digitally excluded, ministers of religion, certain under-parlour individuals etc. (legislation.gov.uk)
Actionable Advice Before April 2026
- Check your qualifying income: use your 2024-25 tax return (turns out by 31 Jan 2026) to see if your combined income from self-employment and property exceeds £50,000.
- Upgrade your software: Ensure your bookkeeping or accounting tools are HMRC-compatible. Perform some trial quarterly updates so you're ready.
- Organize your records: Digital versions of invoices, receipts, expenses — sorted by category — make both quarterly updates and full annual returns smoother.
- Engage a tax agent early (if applicable): If someone else prepares your tax returns, ensure they understand the MTD obligations and can access your digital records.
Real-world Example
Scenario: Clara is a landlord who earns £45,000 in rent plus runs a small side business making jewellery, earning £10,000 turnover (before expenses). Her qualifying income is £55,000.
- From 6 April 2026, Clara must keep digital records, use compatible software, send quarterly summaries of both income sources, and file her Self Assessment via the digital system by the deadline.
- If Clara misses one quarterly update deadline, she gets a penalty point — no direct fine yet. But further late or missed deadlines add points; crossing a threshold might lead to a financial penalty.
Why It Matters & Benefits
- Helps avoid “January surprises” by seeing estimated liabilities all year.
- Encourages better financial organization — separating expenses early, classifying properly, reduces risk of lost claims.
- Long-term benefit for advisers and agents: more streamlined workflows, fewer manual corrections.
This is a big change, but with preparation and systems in place, it’s manageable — and ultimately rewarding if you avoid mistakes and manage cash flow intelligently.
