What is MTD for ITSA?
MTD for ITSA is part of HMRC’s broader initiative to modernise the UK tax system by requiring digital record-keeping and online submissions.

Under MTD for ITSA, affected taxpayers must:
Maintain digital records of income and expenses using compatible accounting software.
Submit quarterly updates to HMRC, providing real-time tax information instead of the traditional annual tax return.
Adhere to revised reporting requirements, with penalties for non-compliance.
Implementation timeline
The rollout of MTD for ITSA will be phased to allow businesses to adjust:
April 2026: Mandatory for those earning over £50,000 annually.
April 2027: Mandatory for those earning over £30,000 annually.
