On 30 October 2026, HMRC released Edition 8 of the Making Tax Digital (MTD) for Income Tax software developer newsletter. This correspondence provides critical updates for software developers building solutions compatible with HMRC’s MTD APIs. The newsletter covers recent API changes, upcoming mandates, and technical guidance for the 2026-27 tax year. MTD for Income Tax requires self-employed individuals and landlords with annual income over £50,000 to keep digital records and submit quarterly updates from April 2026, with the threshold lowering to £30,000 from April 2027.
Key Takeaways
