Overview of MTD for Income Tax (ITSA)
- Who is affected first: From 6 April 2026, self-employed individuals and landlords with qualifying income over £50,000 will be required to use Making Tax Digital for Income Tax (MTD-ITSA). (gov.uk)
- Phase 2: From 6 April 2027, the requirement lowers to those with qualifying income over £30,000. Later, for tax year 2028-29, the threshold will drop to £20,000. (gov.uk)
- Qualifying income means gross self-employment and property income before deductions. Only unincorporated businesses and landlords (sole traders etc.). Partnerships are not yet mandated. (gov.uk)
Key Compliance Steps
- Select compatible software early – you’ll need digital record-keeping and ability to submit quarterly updates.
- Maintain accurate digital records of all income & expenses (including property income), beginning now in preparation. Late adoption leads to risk of error.
- Understand Quarterly Updates – instead of one annual Self Assessment, you’ll send four updates per year as well as annual final declaration. Deadlines align with VAT schedule (7th of the month following quarter end for many). (developer.service.hmrc.gov.uk)
- Review exemptions or digital exclusion status if relevant – guidance updated to clarify who qualifies for digital exclusion. (gov.uk)
- Budget for administrative burden – some cost and time investment up front; but benefits include fewer errors, more predictive tax payments. Costs vs savings estimated in published analysis. (gov.uk)
Practical Scenario
Ben, a landlord in Manchester with £55,000 gross rental income and £10,000 from a small online business (self-employed), reaches qualifying income threshold in 2026. He must:
- Register or ensure his software is MTD-compliant by April 2026.
- Keep digital records of income & expenses for both property and trade.
- Submit quarterly income and expense updates (likely four times a year) plus a final annual declaration via software.
Failing to do so risks penalties, errors in calculation, loss of time.
Actionable Advice
- Trial software now ahead of legislated mandation—take early advantage of optional use to avoid scramble.
- Train staff or yourself to understand software entries, depreciation, expenses, shared costs (often tricky with property).
- Retain all receipts digitally and ensure reliable backup.
- Review your tax planning under the non-dom changes alongside MTD; foreign income may need disclosures via MTD. “Qualifying income” currently excludes foreign income, but rules may evolve. (gov.uk)
MTD-ITSA will become a cornerstone of compliance in the UK tax landscape. Being proactive will reduce risk and make the transition significantly smoother.
