MTD ITSA for UK Landlords: The 2026 Compliance Guide
Making Tax Digital for Income Tax Self Assessment (MTD ITSA) applies from 6 April 2026 to landlords and sole traders with qualifying income over £50,000, from April 2027 over £30,000 and from April 2028 over £20,000. This guide explains the quarterly digital submissions and the software requirements. Rentalize is not HMRC-recognised MTD software; it keeps rent and categorised expense records that export to CSV for filing in HMRC-recognised software.

This is operational guidance, not legal advice. For specific cases, take advice from a qualified property lawyer. Rentalize keeps the records these rules turn on; the legal interpretation is your responsibility.
Why it matters
Making Tax Digital for Income Tax is an HMRC requirement, separate from the Renters Rights Act, and it applies across the UK. It started on 6 April 2026 for qualifying income over £50,000, with lower thresholds from April 2027 and April 2028, as set out above.
How Rentalize handles MTD ITSA for Landlords
Rentalize is not HMRC-recognised MTD software and does not submit anything to HMRC. It keeps rent and categorised expense records that export to CSV for filing in HMRC-recognised software.
