What Is MTD for Income Tax?
Making Tax Digital (MTD) for Income Tax is a major administrative reform requiring eligible sole traders and landlords to keep digital records and submit tax updates quarterly, rather than once a year.(gov.uk) It’s intended to increase accuracy, make tax easier, and improve cash flow visibility.
Who Must Comply and When
| Threshold | Compliance Start Date |
|---|---|
| Qualifying income from self-employment/property over £50,000/year | 6 April 2026 (gov.uk) |
| Over £30,000/year | From April 2027 (gov.uk) |
| Over £20,000/year | From April 2028 (gov.uk) |
Qualifying income includes gross receipts from self-employment and property before deducting expenses.(gov.uk)
What You’ll Need to Do — Step by Step
- Update your software: Use MTD-compatible tools for accounting, records, and submission.
- Create digital records: From 6 April 2026 (or earlier if your accounting period ends on 31 March) — record income, expenses, dates, categories.(gov.uk)
- Send quarterly updates: By set deadlines (e.g. first update by 7 August 2026 for standard periods).(gov.uk)
- Submit final declaration: End-of-year tax return via compatible software by 31 January following the tax year.
- Check for exemptions or deferrals: Certain groups (e.g. non-UK resident entertainers, ministers of religion etc.) may be exempt or deferred.(gov.uk)
Penalties and Compliance Risks
A points-based penalty system will be introduced. If you miss a quarterly or annual obligation, you'll get a point. Accumulate too many points, and financial penalties follow.(assets.publishing.service.gov.uk)
Risk areas include:
- Poor record-keeping or using non-approved software.
- Missing deadlines for quarterly updates.
- Failing to understand qualifying income, especially where multiple income sources exist.
Example
Bob is a landlord who earns £60,000 gross property income per year. From April 2026, Bob must use digital records, submit quarterly summaries, and file his tax return via compatible software. If he misses a quarterly update by the deadline, he gets a penalty point; miss another, he may receive a financial penalty. To avoid this, Bob ensures he uses reliable software, sets reminders, and keeps accurate records as his business earns above the threshold.
Key Takeaways for Businesses & Landlords
- Check whether you exceed the threshold now or expect to next year.
- Invest now in compatible record-keeping software, training, or advisory support.
- Plan cash flow around quarterly updates rather than relying entirely on the annual return.
- Keep all of your existing invoices, receipts and expense details digitised from the start of the new period.
Impact of Frozen Thresholds
Because thresholds are being held steady until April 2031, what counts as being “in a certain band” won’t change even as inflation pushes incomes higher. That tends to pull more income into higher taxed categories over time — justifying greater care in planning.(gov.uk)
