What Is MTD for Income Tax (ITSA)?
MTD for ITSA is HMRC’s program mandating quarterly digital reporting of income and expenses for individuals with self-employment or property income (“sole traders and landlords”), using MTD-compatible software. This replaces paper records and annual-only filings for those with higher incomes. (gov.uk)
Who’s In Scope from 6 April 2026
- Sole traders and landlords with qualifying income over £50,000 in trade or property income (gross, before expenses) based on the 2024-25 tax year. (gov.uk)
- From 6 April 2027, the threshold drops to £30,000.
- From 6 April 2028, threshold will further drop to £20,000.
- Non-UK residents with self-employment or property income in the UK are also included; residence/domicile do not exempt scope. (gov.uk)
What You Must Do in Practice
- Use compatible software: you must keep digital records using software approved by HMRC and send four quarterly summary reports plus the final Self-Assessment declaration. (gov.uk)
- Understanding deadlines: quarterly updates due roughly in August, November, February and May; final declaration and full tax filing remain due by 31 January following end of tax year.
- Handling changes in circumstances: if your sources of income change (e.g. you stop being a landlord but remain self-employed or vice versa), obligations may still persist. (gov.uk)
Examples
- Example A: Jane is a landlord in 2024-25 with property income of £60,000 (gross), no trade income. She must enrol in MTD ITSA from 6 April 2026 and begin quarterly reporting.
- Example B: Mike is self-employed with trade income of £45,000 and also has £10,000 of property income. His qualifying income is £55,000 → falls in scope 2026.
- Example C: Paula’s trade income in 2024-25 is £52,000, but in 2025-26 it drops to £25,000. She must begin MTD ITSA in April 2026 anyway because eligibility is assessed on 2024-25. Exiting the regime has its own rules.
Consequences of Non-Compliance
- Missing registration or failing to use compatible software could lead to errors in your tax estimates and possibly penalties (though initially HMRC has indicated penalties for late quarterly updates won’t apply during the testing/familiarisation phase in early periods). (gov.uk)
- Incorrect software or late submission of final declaration retains the standard risks associated with Self-Assessment.
Actionable Advice for Getting Ready
- Audit your income streams: calculate qualifying income for 2024-25 now.
- Choose MTD-compatible software: explore options, test functionality before deadlines.
- Setup digital record-keeping: methodically track income and expenditures—hybrid or manual records won’t suffice.
- Register early once you know you're in scope; agents can register on behalf of clients.
- Stay updated via HMRC guidance & review agent updates such as Issue 142 in April 2026 for important reminders. (gov.uk)
Broader Considerations
- Compliance costs may rise initially (software, training) but long-term benefits: fewer end-year surprises, errors reduced, better visibility of tax position.
- If you fall close to thresholds, watch projections. Growth or drop-offs may alter your status.
- Seek professional advice if overseas income, partnerships, or other complex structures are involved.
