What is MTD for ITSA?
MTD for ITSA is HMRC’s initiative to require digital record-keeping and quarterly reporting of income and expenses for certain self-employed individuals and landlords. It’s part of a broader effort to modernise the tax system and reduce tax errors. (gov.uk)
Who is in scope and when it begins
- From 6 April 2026, individuals with qualifying trading or property income over £50,000 will be required to comply. (gov.uk)
- From 6 April 2027, the income threshold reduces to £30,000. (gov.uk)
- A further expansion is planned: from 6 April 2028, those with income over £20,000 will also be brought in. (gov.uk)
Key requirements under MTD for ITSA
- Keep digital records of all relevant income and expenses using HMRC-approved software. (gov.uk)
- Submit quarterly updates that report cumulative income, expenses, and reliefs. These are not full tax returns but interim information. (gov.uk)
- Then continue submitting the end-of-year Self Assessment return through compatible software. (gov.uk)
What this means for you (if applicable)
- Compliance burden: You’ll need software that supports quarterly submissions; manual or paper-based systems will no longer suffice. Small businesses might face transitional costs. (gov.uk)
- Penalties: During the testing phase, late quarterly updates won’t trigger penalty points—but end-of-year late returns will. Once mandated, penalties for late submissions and updates will apply. (gov.uk)
- Budgeting and cash flow: With more frequent reporting, you’ll be more aware of tax liability throughout the year; better planning becomes essential.
What you should do now (actionable steps)
- Assess your income streams for the last 12 months to see if your qualifying income exceeds £50,000.
- Plan for software: research and choose HMRC-approved software that supports MTD ITSA (digital records, quarterly updates, returns).
- Start keeping digital records even before mandated, so your systems are ready by April 2026.
- Talk to your accountant or tax adviser about how MTD ITSA affects your reliefs, allowable expenses, and tax planning.
- Budget for costs, both financial (software, bookkeeping) and time (record-keeping, backlog if digitizing old records).
Example scenario
Sarah is a self-employed graphic designer with property rental income. Combined gross income (before expenses) from business and property over the last year is £55,000. From 6 April 2026, she’ll need to:
- Keep digital records of her design business and rental properties.
- Submit quarterly updates (not full Self Assessment until year-end) via compatible software.
- Prepare her tax planning with more frequent insights into liabilities.
If instead her self-employment + rental income were £45,000, she’d have until April 2027 to become obliged under MTD ITSA. But voluntarily joining early may bring benefits.
Benefits & challenges
| Benefit | Challenge |
|---|---|
| More accurate tax forecasting and less surprise liabilities | Upfront cost of software and adapting to new processes |
| Reduced error and simpler digital record-keeping | Learning curve and potential administrative burden for smaller operators |
| Better integration with accounting tools and advisers | Need for consistent record-keeping across all streams |
Bottom line: If you're a sole trader or landlord with income over £50,000 from business and/or property, April 2026 is when MTD for ITSA becomes mandatory. If you're near that threshold, prepare early—digital tools, reliable record-keeping, and advice will become indispensable.
