MTD for Income Tax: from onboarding to filing with Xero
Britain's self-employed and landlords face their biggest tax compliance shift in decades as Making Tax Digital for Income Tax becomes mandatory in weeks.
Key takeaways
- •From 6 April 2026, sole traders and landlords with combined self-employment and property income over £50,000 must switch from annual Self Assessment returns to digital record-keeping and quarterly updates via compatible software.
- •The first quarterly filing deadline hits on 7 August 2026, with a new penalty points system for late submissions that can lead to £200 fines after two infractions, though initial leniency applies to the first four updates for 2026 joiners.
- •The reform aims to reduce errors and close the tax gap but imposes higher administrative burdens and software costs on affected individuals, many of whom have resisted the change.
The Digital Tax Overhaul
Making Tax Digital (MTD) for Income Tax Self Assessment (ITSA) marks the next major phase in HMRC's long-running effort to modernise the UK's tax system. After years of delays and pilot schemes, the mandatory rollout begins on 6 April 2026 for those whose qualifying gross income from self-employment and/or property exceeded £50,000 in the 2024-25 tax year. This threshold drops to £30,000 from April 2027 and £20,000 from April 2028, eventually capturing far more people.
The change replaces the traditional once-a-year Self Assessment return with ongoing digital obligations. Affected taxpayers must maintain records in HMRC-recognised software and submit quarterly updates summarising income and expenses. These updates feed into an eventual annual 'Final Declaration' that determines the final tax liability. The first such update, covering April to July 2026, falls due by 7 August 2026.
Stakes are high for the roughly 780,000 to 900,000 individuals entering the regime in the initial wave, including freelancers, consultants, tradespeople, and landlords. Non-compliance triggers a points-based penalty regime, where late filings accrue points leading to fixed fines—£200 after two points—and additional penalties for late payment. While HMRC has softened the landing by waiving points for the first four quarterly updates in 2026, the system still demands timely action.
Costs extend beyond fines. Many must purchase or subscribe to compatible software, potentially hundreds of pounds annually, and invest time in setup, digital record-keeping, and learning new processes. Smaller operators, accustomed to spreadsheets or paper, face the steepest adjustment.
Tensions persist around the policy's value. HMRC argues digitisation will curb errors, improve compliance, and narrow the tax gap. Critics, including some professional bodies and affected groups, highlight disproportionate burdens on lower-margin businesses, privacy concerns over constant data flows, and limited evidence that quarterly reporting materially improves accuracy for simple affairs. Exemptions remain narrow, with only 661 approvals from over 1,200 applications by early 2026.
Recent updates, including Budget 2025 easements and clarified guidance, reflect ongoing refinements, but the core shift is irreversible and imminent.
