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 earning over £50,000 have had to file quarterly digital reports to HMRC. No more annual Self Assessment only. HMRC has waived late-filing penalties for 2026-27, but the updates are still mandatory 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.
LetSort handles the compliance bits that FreeAgent and Landlord Studio don't, and works alongside the tools you already use.

A single late MTD filing costs £200. A single RRA breach starts at £4,000. LetSort costs less per month than one mistake.
Sourced, dated guidance on both laws, from the team that files against the HMRC API.
For MTD software HMRC never says “approved”, only “recognised”, and it does not recommend any product. It scrapped its browsable list in July 2025 for a personalised finder that returned 100 recognised products for a landlord when we ran it, 28 of them free. Here is how to check any product yourself.

HMRC moved version 7.0 of its Individual Losses API to production on 16 June 2026, and version 6.0 has rejected any tax year after 2025-26 since January. Two separate resources became one, with three endpoints. A landlord never sees it; their software either kept up or it did not.

Every MTD filing sends HMRC a description of the machine that made it: your browser, screen size, time zone, IP and connection port. By law. Here are the fourteen headers we send, the two we do not, and the one that made us build a dedicated server to collect it.

Every guide stops at “click connect and your software does the rest”. Here is the rest: six API calls, eleven mandatory surveillance headers about your own machine, a four-hour token, and the moment HMRC decides whether to trust you.

One calendar for both regimes. Which duties are real today, which are not in force yet, and which quietly stopped existing on 1 May 2026. Most landlord calendars you will find online contain at least one duty that no longer exists.

Much of the internet says mortgage interest is not reported quarterly under Making Tax Digital. HMRC’s own Update Notice says it is. Put it in the wrong box and HMRC deducts it in full and gives you no relief, and the figures still look plausible.
