MTD for Income Tax vs Self Assessment: The Key Differences

From 6 April 2026, Making Tax Digital for Income Tax replaced the annual Self Assessment return for sole traders and landlords earning above £50,000. Under MTD, you submit four quarterly digital updates plus a Final Declaration by 31 January each year using HMRC-approved software. Your tax rates, payment dates, and allowances stay exactly the same, only how and how often you report to HMRC has changed.
