What’s Changing & Who's Affected
From 6 April 2026, sole traders and landlords whose qualifying income (self-employment plus rental, excluding certain allowances) exceeds £50,000 in the previous tax year (2024-25) will be required to use Making Tax Digital for Income Tax (MTD for ITSA). That means maintaining digital records, using compatible software and submitting quarterly updates of income and expenses. (gov.uk)
There are phased reductions too:
- Income over £30,000: join from April 2027. (gov.uk)
- Income over £20,000: onward from April 2028. (gov.uk)
Key Requirements & Important Dates
| What | When it starts | Deadline or impact |
|---|---|---|
| Digital record keeping & quarterly updates | From 6 April 2026 | First quarterly report due 7 August 2026. (gov.uk) |
| File annual Self Assessment return | After end of tax year (5 April 2027 for year starting Apr-2026) | 31 January 2028 for tax year 2026-27. (gov.uk) |
| Penalty relief for early slip-ups | First 12 months of MTD for ITSA | No penalty points for late updates during the 12-month grace period. (gov.uk) |
What Counts as “Qualifying Income”?
Qualifying income includes:
- Self-employment income (after expenses)
- Property income (both UK and foreign properties combined separately) (gov.uk)
And excludes if:
- Income was below personal allowances and property or trading income allowances in prior returns, under certain thresholds. (gov.uk)
Benefits & Challenges
Pros:
- Fewer surprises at tax return time — each quarter update gives clearer cash flow forecasts.
- Reduced errors and missing receipts — digital systems force better record keeping.
- Ease of planning — you can adjust deductions or revenue recognition during the year rather than at year-end.
Cons:
- Need to invest in software or accounting tools if you haven’t already.
- A learning curve for switching from annual to quarterly recordkeeping.
- Potential need to engage an accountant or agent experienced with digital filing if queries or mishaps occur.
Practical Actions You Should Take Now
- Choose software early: Select MTD-compatible software now so you have time to test it ahead of first quarterly deadline. Many free or lower-cost versions are available. (gov.uk)
- Gather historic records: Ensure your books, rent receipts, expenses and self-employment income history for 2024-25 are in order — many of those figures determine if you’re brought into scope.
- Check if you’re exempt: Digital barriers, physical disability, or low income may make you eligible for exemptions. Apply to HMRC in time. (gov.uk)
- Agent/Advisor: If you use an accounting agent, make sure they know about these changes and are ready to handle quarterly updates.
- Cash Flow Forecasting: Since your tax liability may be spread or better predicted, plan your cash flow quarterly so payments don’t pile up unexpectedly.
Example Scenario
Bob is a landlord with gross rental income of £60,000 per annum. After deductions, his qualifying income is £55,000 for tax year 2024-25. Therefore, from 6 April 2026, Bob must:
- Keep digital records of all rental income and allowable expenses.
- Submit four quarterly updates (due 7 August 2026, 7 November, 7 February 2027, and 7 May 2027) of summary income & expenses.
- File Self-Assessment tax return by 31 January 2027, for the 2025-26 year as usual. But from tax year 2026-27, the return will be partially pre-filled by quarterly updates.
- Not get penalty points for occasional quarter-late updates during the first 12-months grace period.
Long-Term Considerations
- When thresholds reduce in April 2027 and 2028, more sole traders and landlords will be brought in — plan ahead for lower-income years.
- Expand digital skills or train staff; early familiarity pays off.
- Monitor HMRC guidance updates — design and software approvals may shift.
Final Word
MTD for Income Tax isn’t just another HMRC program – it represents a structural shift in how tax is reported and paid. If you’re already over £50,000 qualifying income, this is urgent. If not yet reached, these changes are coming and earlier preparation will reduce pain points later.
