HM Revenue and Customs (HMRC) has issued a critical alert to more than 864,000 sole traders and landlords reminding them that the first mandatory Making Tax Digital (MTD) for income tax quarterly update deadline is 7 August 2026.

 The Core Requirements

This landmark change signals a shift away from traditional, once-a-year tax reporting toward an interconnected digital tracking system:

• The Threshold: The rules apply to individuals with a combined qualifying gross income from self-employment and property exceeding £50,000.
• The Task: Affected taxpayers must submit a short digital summary of their business income and expenses for the first three months of the tax year.
• The Mechanism: Submissions cannot be done manually; they must be completed using HMRC-compatible software.
• The Tax Return: These quarterly updates do not replace the annual Self Assessment Tax Return.  Taxpayers must still submit their standard annual returns and pay any outstanding taxes by 31 January 2027.

Penalty Relief and Future Rollout

• First-Year Grace: Bo late-submission penalty points will be issued for missed quarterly updates during the first year of the scheme.
• Standard Penalties Apply: Traditional penalties for filing your Self Assessment return late or missing a payment remain fully active.
• Points-Based Fines: Starting in the second year (2027/28), missed quarterly deadlines will accumulate penalty points, eventually triggering a £200 fixed fine.
• Upcoming Lower Thresholds: The digital reporting net will expand to those earning over £30,000 in April 2027, and over £20,000 in April 2028.
