What is Making Tax Digital (MTD) for Income Tax?
MTD for Income Tax Self Assessment (ITSA) is a UK government initiative requiring those in scope to use compatible software to keep digital records, submit quarterly updates of income and expenses, and make a final declaration at year-end. (gov.uk)
Who is affected?
- Sole traders and landlords with combined income from self-employment and property exceeding £50,000 per year. (gov.uk)
- If your self-employed and/or property income is below that but expected to increase, planning ahead is still wise. Software acquisition and familiarity take time.
Key timelines & deadlines
| Requirement | Deadline | First Reporting Period | First Final Declaration Due |
|---|---|---|---|
| Quarterly updates | From 6 April 2026 | Quadrant 1: 6 April–5 July 2026 | Final declaration due 31 January 2028 |
What you need to do now
- Choose HMRC-recognised software that supports sending quarterly returns. Check the gov.uk software finder list. (gov.uk)
- Set up digital bookkeeping to capture incomes, expenses with proper categorisation.
- Plan cash flow so you can manage quarterly liabilities (Income Tax, NICs, etc.) rather than one large sum at year-end.
- Train accounting staff or yourself––this is a structural change in reporting rhythm.
Practical example
Sarah runs holiday lets and freelance writing, with combined revenue of £60,000/year. Under old rules, she could file once after year-end and pay tax then. From April 2026:
- She must submit quarterly updates (e.g. by 7 August 2026 covering income/expenses to 5 July 2026)
- Use digital software to send updates. Light-touch: only revenue, expenses, net profit.
- Her final declaration (covering the full 2026-27 tax year) is due 31 January 2028.
What are benefits & challenges?
Benefits
- Smoother cashflow and better tax forecasting
- Less risk of big surprises at year-end
- Digital record-keeping often saves time and avoids errors
Challenges
- Initial setup costs and learning curve
- Need for reliable digital tools and possibly accounting support
- Risk of missing deadlines, triggering penalties (first late actions expected from April 2027)

Takeaway: If you're a sole trader or landlord near or above the threshold, begin transitioning now. The quarterly rhythm may feel odd at first, but digital readiness will be essential in the long term.
