For the first time, UK landlords face mandatory digital tax reporting and sweeping tenancy regulation changes in the same month. Miss either one, and the fines stack up fast.
Since April 2026, landlords with qualifying income over £50,000 in 2024-25, unless exempt, have had to file quarterly digital reports to HMRC. No more annual Self Assessment only. HMRC will not apply penalty points for late quarterly updates in 2026-27, but the updates are still mandatory. A late 2025-26 tax return, due 31 January 2027, still costs £100 under the current rules, and late payment still carries interest and penalties.
Section 21 is abolished. All tenancies are now periodic. New rules govern rent increases, pet requests, eviction grounds, rent in advance, and rental bidding. Every obligation carries fines, up to £40,000 for serious breaches.

Sourced, dated guidance on both laws, from the team building against the HMRC API.
Much of the internet says mortgage interest is not reported quarterly under Making Tax Digital. HMRC’s own quarterly update direction says it is. Put it in the wrong box and HMRC deducts it in full instead of restricting it, which understates a higher-rate landlord’s tax, and the figures still look plausible.

MTD quarterly updates run on standard or calendar periods. The choice moves the period end, not the deadline: both file on 7 August, 7 November, 7 February and 7 May. It locks once you file for the year, so most landlords next choose for 2027-28. Here is how to decide.

HMRC’s guidance mostly says “compatible” MTD software, elsewhere it says “recognised”, and it tells software makers not to claim “approved”. It does not recommend any product. It replaced its software table with a finder tool in July 2025. On 6 November 2026 the finder showed 165 results for sole traders and landlords combined, and an update note on HMRC’s guidance page says products in development are listed too. Here is how to check any product yourself.

HMRC moved version 7.0 of its Individual Losses API to production on 16 June 2026. Version 6.0 is capped at 2025-26 and HMRC plans to retire it on 1 August 2028. Software that has not moved will be rejected when landlords send losses for 2026-27, from 6 April 2027.

By law, MTD software providers must send HMRC details of the device and connection you file from: your browser, screen size, time zone, IP, connection port and the identifier you sign in with. HMRC lists sixteen headers for web software. Here are the fourteen we normally send, the two we do not, and the one that made us build a small service to collect it.

Many guides stop at “connect and your software does the rest”. Here is the rest: one PUT per income source and the supporting API calls around it, sixteen fraud prevention headers, several of them about your own device, a four-hour token and an 18-month authorisation.
