What is MTD for Income Tax and Key Dates
Making Tax Digital for Income Tax is a major compliance reform. From 6 April 2026, sole traders and landlords with qualifying income over £50,000 must:
- Keep digital records;
- Use MTD-compatible software;
- Submit quarterly summaries of income & expenses to HMRC. (gov.uk) For those whose qualifying income is over £30,000, MTD becomes compulsory from April 2027, and for over £20,000 from April 2028. (gov.uk)
What Counts as Qualifying Income
Qualifying income includes gross income (before any deductions or allowances) from self-employment and property rental business. If you fall above the thresholds, even if much of your income is via property, you’ll be caught. (gov.uk)
Actionable Compliance Steps
1. Select software early: Choose digital accounting software approved by HMRC, capable of quarterly submissions. Give yourself time to test it. Many existing MTD for VAT users have suitable tools.
2. Digital record-keeping: Maintain receipts, bank statements, invoices & expense logs digitally. Keep up-to-date throughout tax year.
3. Join the testing programme: HMRC encourages eligible users to sign up early to become familiar without penalties. (gov.uk)
4. Prepare for changeover: Align your financial systems now to produce quarterly summaries; avoid leaving all income and expenses until year end.
5. Understand grace periods & support: Initially, HMRC won’t impose late penalties during the testing phase. Also, there are customer support teams. (gov.uk)
Common Mistakes to Avoid
- Underestimating record-keeping: mixing personal and business expenses without clear separation.
- Missing threshold changes: move above qualifying income and don’t realise you’re in scope.
- Late software adoption: using inadequate or incompatible software at the last minute.
- Ignoring property income: many landlords may not think MTD applies due to rental income, but it does count if gross income threshold exceeded.
Example Scenarios
- Self-employed Sara has £60,000 in gross income split between consultancy and two small rental properties. From April 2026, she must keep digital records, use software, and send quarterly updates.
- Landlord Tim whose rental income is £40,000 but no self-employment: he only comes under MTD in April 2027 when threshold drops to £30,000. Meanwhile, he should still prepare systems now.
Why This Matters
- Enhanced transparency helps avoid under-reporting and penalties.
- Quarterly reporting offers better cash flow management—less shock at year-end liability.
- Early compliance avoids last-minute scramble and risk of non-compliance.
Beyond compliance, MTD aligns with broader HMRC goals: reducing the tax gap, simplifying taxpayer experience, modernising services. Be ready. Be organised. This transition is inevitable—and early action pays dividends.
