MTD ITSA: the quarterly tax burden 864,000 UK landlords can't dodge.
From 6 April 2026 every UK sole trader or landlord whose combined self-employment + property income for 2024-25 was over £50,000 must keep digital records and file four quarterly updates a year to HMRC through commercial Making Tax Digital software, plus a final end-of-year declaration. The threshold drops to £30,000 in April 2027 and £20,000 in April 2028. HMRC's own briefing puts the first wave at ~864,000 operators. Sign-up is not automatic — operators must actively enrol. Spreadsheets alone are not accepted; HMRC-recognised software is mandatory. On landlord forums, portfolio operators report quotes of "around £1k per year" for compliant tools, on a population already, in their own words, "hammered left, right and centre." ICAEW has formally listed the design of obligations for jointly-owned property as a key concern; landlord communities openly discuss selling stock to drop below the threshold rather than absorb the quarterly admin.
01The pain
The structural change took effect on 6 April 2026 and is documented in HMRC's own communications and accountancy-body briefings. HMRC's February 2026 press release records the count and the start date verbatim — "Around 864,000 sole traders and landlords" face "new digital tax requirements", with "Making Tax Digital for Income Tax (MTD)" coming into effect on "6 April 2026".1 The same release records the threshold tier: the requirement applies to operators with "qualifying income above £50,000", dropping to "those with qualifying income above £30,000 from 6 April 2027" and "£20,000 from 6 April 2028".1 HMRC's enrolment guidance is explicit that the obligation is active rather than passive: operators "need to sign up for Making Tax Digital for Income Tax" — the system does not enrol them automatically, even where HMRC has written to identify them as in-scope.2 Bytestart's industry write-up captures the same scope in operator-facing language: "Making Tax Digital, the new digital tax system, comes into effect for taxpayers with self-employment and property income from April 2026"; the obligation is "keep digital records and submit quarterly updates", with the headcount confirmed at "around 864,000 sole traders and landlords".4
What makes the change land disproportionately on UK landlords is the structural surface of property income: jointly-held properties, dual-track portfolios run alongside a separate trade, and a population of retiree and accidental landlords who have never used cloud accounting software. The Independent Landlord's MTD write-up records the cost-and-software reality landlords are confronting in the operators' own words — "HMRC has stated that the use of free software won't be possible", "Once you sign up to MTD, you will need to use a commercial software package that is recognised by HMRC", and on forum threads, portfolio landlords report quotes "around £1k per year" for compliant property-aware tools (e.g. Hammock).3 The same write-up captures the operator-side framing — landlords describing themselves as "hammered left, right and centre" by the cumulative compliance, software and tax-stack cost — and lists the unresolved design questions stacking up against the start date: jointly-owned property where two co-owners must somehow split a single rental ledger across two MTD feeds; HMRC's "only one agent can access a customer's MTD account" limit, which breaks the common pattern of one accountant for the trade and another for the property portfolio; and year-end declaration uncertainty for non-property income (foreign dividends, charitable giving, capital gains) where landlords say there is "very little to give me confidence" the available platforms can carry the full return.3
The wider operating context is documented across the same regulator-and-accountancy-body surface. HMRC's release frames MTD as a structural shift in how Income Tax is administered, with the Director General for Customer Services, Craig Ottley-Thistlethwaite, quoted as saying "MTD for Income Tax is the most significant change to the Self Assessment regime since its introduction in 1997" and urging operators to "prepare now".1 The penalty regime is points-based: under the new rules, late quarterly submissions accumulate points, with a "£200 penalty" triggered after four points are reached; a 12-month grace on penalties applies through the first year of the regime, with full sanctions live from April 2027.3,4 ICAEW has formally listed the design of obligations for jointly-owned property as a key concern in its public engagement with HMRC, and landlord communities are openly discussing selling property stock to drop combined income below the £50,000 threshold rather than absorb the quarterly admin and the recurring software cost.3 UK landlords and sole-trader portfolio operators report standing up new digital bookkeeping habits, choosing between bridging-software-plus-spreadsheet and full property-aware accounting tools, splitting jointly-owned ledgers, redesigning the agent relationship around the one-agent limit, and — for those just over the £50,000 line — running the arithmetic on whether selling a property is cheaper than the cumulative compliance cost.1,2,3,4

02Who solves this today
UK-market vendors that publicly self-market on their own homepage to landlords or sole traders on the Making Tax Digital for Income Tax niche — software whose front-page copy explicitly names MTD / Making Tax Digital AND landlord, property-income, sole-trader or quarterly-update workflows. Each entry verified live and self-marketed in the niche on the date of writing. Inclusion is not endorsement. The list is intentionally narrow.
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 accountancy-body / trade-press write-ups cited above in section 01 are the source of the operator-side narrative, not solution providers.
