UK forces 864,000 landlords into quarterly Making Tax Digital filings from April 2026.
Two flats and a small consultancy. On 6 April 2026 that landlord stops filing one Self Assessment return a year and starts filing five: four quarterly Making Tax Digital (MTD) updates plus a final declaration, in commercial software HM Revenue & Customs (HMRC) has approved. The trigger is one combined number, £50,000 of self-employment plus property income for 2024-25. It drops to £30,000 in April 2027 and £20,000 in April 2028. HMRC counts ~864,000 in the first wave. Landlord forums quote "around £1k per year" for compliant tools, on a population that already calls itself "hammered left, right and centre."
01The pain
"Around £1,000 a year." That's what UK landlord forums quote each other for the bookkeeping software HM Revenue & Customs (HMRC) will recognise from 6 April 2026. The Independent Landlord logs the figure verbatim, alongside HMRC's flat line that "the use of free software won't be possible" and the rule that anyone signed up "will need to use a commercial software package that is recognised by HMRC."3 Spreadsheets alone are out.
From that date, around "864,000 sole traders and landlords" whose combined self-employment plus property income for 2024-25 cleared £50,000 stop filing one Self Assessment a year and start filing five: four quarterly Making Tax Digital updates plus a final declaration.1 The threshold drops to £30,000 in April 2027 and £20,000 in April 2028. HMRC's Director General for Customer Services Craig Ottley-Thistlethwaite calls it "the most significant change to the Self Assessment regime since its introduction in 1997."1 Bytestart's industry write-up confirms scope and headcount.4 Sign-up is active, not automatic. Even after HMRC writes to identify a landlord, that landlord "need[s] to sign up for Making Tax Digital for Income Tax" themselves.2
What lands hardest is the messy shape of UK property income. Co-owned flats, typically held jointly by spouses, must somehow split a single rental ledger across two MTD feeds. The Institute of Chartered Accountants in England and Wales (ICAEW) has formally raised the problem with HMRC; neither the legislation nor the recognised software has answered it.3 A landlord with a consultancy on one accountant and a buy-to-let portfolio on another hits HMRC's "only one agent" ceiling: one professional takes both books, or one of them goes.3 On foreign dividends, charitable giving and capital gains, landlords say there is "very little to give me confidence" the platforms can carry the year-end declaration.3
Four points, then a £200 penalty, live from April 2027 once the 12-month grace ends.3,4 The cheapest exit is already trending on the forums: sell a flat, drop combined income under £50,000, file once a year for one more year. Then 2027 catches the £30,000 cohort, and 2028 the £20,000 one.3 The arithmetic is no longer political. It's a spreadsheet. The last one HMRC will accept.

02Who solves this today
UK vendors whose own homepage names landlords or sole traders on the Making Tax Digital for Income Tax niche. Front-page copy must pair MTD with property income, quarterly updates or Self Assessment. Each entry verified live on the date of writing. Inclusion is not endorsement.
Listed providers publicly market to UK landlords or sole traders on the Making Tax Digital for Income Tax niche from their own homepages. Inclusion is not endorsement. Several adjacent vendors were considered and excluded. Coconut's homepage was unreachable on the date of writing (DNS / connection refused) and was therefore dropped under the verify-before-list rule. QuickBooks UK Self-Employed and Xero are HMRC-recognised but their UK front-page copy frames MTD for Income Tax as one of many compliance surfaces rather than the named landlord / sole-trader niche. Sage Accounting names MTD on the homepage but the landlord-specific framing was thinner than Hammock's and FreeAgent's on the date of writing. All were dropped under the precedent that two-to-three verified entries beat four with a weak link. HMRC's own communications, the GOV.UK guidance pages and the trade-press write-ups cited in section 01 are the source of the operator-side narrative, not solution providers.
