What is MTD for Income Tax Self Assessment?
Making Tax Digital for ITSA is a new requirement designed to move individuals and small businesses into a digital filing system where income, expenses and tax liabilities are documented and submitted digitally. According to recent government sources, the regime will apply to sole traders and landlords with income over £20,000 from April 2028. Late payment penalties for those joining MTD begin from April 2025, while VAT taxpayers and SA taxpayers will face harsher penalties for late or overdue amounts. (gov.uk)
These changes are part of the UK government’s push toward modern tax administration—reducing manual work, increasing accuracy, and improving compliance. HMRC’s “Transformation Roadmap” also promises more digital self-service options and more use of data analytics to support compliance. (gov.uk)
Who is Affected and When
| Role | Current Situation | From April 2025 | From April 2028 |
|---|---|---|---|
| Sole Traders & Landlords with income > £20,000 | Standard Self Assessment | Must join MTD for ITSA | All with income over threshold required |
| VAT Taxpayers | Already under some existing MTD rules | New late penalty regimes apply if late or overdue | Continued compliance under digital rules |
| All taxpayers using SA | Filing using paper/digital tax return | Risk more severe penalties if late | Fully integrated digital regime |
How to Prepare
- Choose digital accounting tools — Ensure your software can record and export your accounts digitally in MTD compatible format.
- Update systems — If using spreadsheets or manual entries, plan migration to approved software.
- Train or hire — Understand the terminology, deadlines, and digital filing procedures. You or your accountant needs to handle them.
- Check your income — If you expect trading, property or other income over £20,000, plan now. If not, monitor trends.
- Understand penalty risks — Late payments will attract stiff penalties that escalate once the regime begins. Paying on time and filing accurately matters more than ever.
Practical Example
Oliver is a landlord receiving rental income of £22,000 per year and incidental income from occasional consultancy of £1,500. He currently uses Self Assessment. Under MTD for ITSA rules from April 2028:
- His rental income being over £20,000 means he’ll be required to join MTD for ITSA.
- He’ll need digital accounts showing income and expenses for both sources.
- Any late payments after threshold or missing digital submission could trigger new penalties.
Actionable Compliance Tips
- Start digitising your records now—don’t wait until the deadline hits.
- Retain all invoices, receipts, and bank statements in digital or scanned format.
- Use HMRC-approved accounting or bookkeeping software.
- Stay alert to HMRC guidance on transitions, including test schemes or pilots.
- Budget for costs of software, training or professional services necessary.
Benefits of Early Adoption
- Lower risk of missing deadlines and incurring penalties.
- Smoother transition for year-end and tax filings.
- Better financial visibility: accurate records help forecasting and tax planning.
- Potential time and cost savings in future once processes are established.
Conclusion
Making Tax Digital for ITSA represents a major compliance shift, especially for sole traders and landlords with income over £20,000. By understanding timelines, adopting digital tools, and planning ahead, taxpayers can meet new requirements confidently. Start early to avoid stress and penalties later.
