Overview of MTD for Income Tax (ITSA)
From 6 April 2026, sole traders and landlords with qualifying income greater than £50,000 from self-employment or property will be required to use Making Tax Digital for Income Tax (MTD ITSA). (gov.uk)
The requirements include:
- Keeping digital records using software that is compatible with HMRC's rules. (gov.uk)
- Submitting quarterly updates of income and expenses, not just an end-of-year return. (gov.uk)
- Filing the full Self Assessment tax return by 31 January following the tax year. (gov.uk)
Who is in Scope & Phasing
| Phase | Qualifying Income Period | Threshold | Mandatory From |
|---|---|---|---|
| Phase 1 | Self-employment & property income over £50,000 (tax year 2024-25) | £50,000 | 6 April 2026 (gov.uk) |
| Phase 2 | If qualifying income over £30,000 (tax year 2025-26) | £30,000 | 6 April 2027 (gov.uk) |
| Phase 3 | Over £20,000 (tax year 2026-27) | £20,000 | 6 April 2028 (gov.uk) |
Compliance Requirements
Key requirements for those impacted:
- Use software that can create, store, correct digital records of income and expenses. Not all software qualifies—check approved listings. (gov.uk)
- Submit regular quarterly updates, even if no profit or income. Deadlines set over the tax year. (gov.uk)
- For 2026-27 tax year: HMRC will not penalise for late quarterly updates during the first year. Penalty points will be introduced only after consistent late reporting. (gov.uk)
Practical Tips for Compliance
- Choose software early: test-drive tools that confirm with HMRC requirements. Allocate budget. (gov.uk)
- Record keeping habits: keep receipts, invoices, categorize expenses properly—remember property income requires greater categorisation. (gov.uk)
- Plan quarterly workflow: allocate time regularly (e.g. monthly) to update income/expenses so quarterly submissions aren’t rushed.
- Agent involvement: If using an accountant, ensure they have an Agent Services Account (ASA) and can sign you up. (gov.uk)
Common Pitfalls & How to Avoid Them
- Missing registration window: not registering by the relevant date can lead to oversight; HMRC often sends letters ahead. If you don’t receive one but meet criteria, it’s still your responsibility. (gov.uk)
- Using non-compatible software or mixing tools without integration or “bridging” software—can lead to submission failures. (gov.uk)
- No income in a period: still must submit quarterly updates, even zero income—non-submission counts.
- Late tax returns: Self Assessment deadlines remain unchanged—full returns due 31 January. Quarterly updates are in addition. (gov.uk)
Example Scenario
Tom is a landlord whose property income plus side self-employment totals £60,000 in the tax year 2024-25. He hasn’t been keeping digital records and uses spreadsheets. For the 2026-27 tax year, Tom must:
- Choose HMRC-approved compatible software, possibly migrate data.
- Ensure records clearly separate property income, expenses, restricted finance costs.
- Submit quarterly updates: Q1 by 7 Aug 2026, Q2 by 7 Nov, Q3 by 7 Feb, Q4 by 7 May 2027.
- File full Self Assessment by 31 Jan 2028.
- Take advantage: no penalty if a quarterly update is late in the first year.
Long-Term Benefits
- More stable cash flow management through regular reporting.
- Early identification of tax liabilities rather than surprises at year-end.
- Potential for reduced professional fees if your processes are automated.
