From 6 April 2026, the way many UK landlords report their rental income to HMRC changes fundamentally. Making Tax Digital for Income Tax turns the once-a-year Self Assessment into a cycle of digital record keeping, four quarterly updates and a final declaration at year end, all filed through recognised software. That shift explains why growing numbers of landlords are switching to dedicated tools: software built for the new rules captures income and expenses as they happen, keeps figures digital throughout and submits each update directly to HMRC, which a spreadsheet alone cannot do.

The new reality of quarterly tax reporting in 2026
Making Tax Digital for Income Tax becomes mandatory on 6 April 2026 for sole traders and landlords whose qualifying income exceeds £50,000 a year. Qualifying income is the gross figure from self-employment and property before any expenses are deducted, added across both sources. That distinction matters: a landlord with several well-let properties can cross the threshold on turnover even when net profit is modest. Anyone unsure where they stand can check their position against HMRC’s published eligibility guidance.
The threshold then falls in steps. From 6 April 2027 the rules apply to qualifying income over £30,000, and from 6 April 2028 to income over £20,000, under the government’s published timetable. HMRC expects around 780,000 sole traders and landlords to fall within scope from April 2026, with roughly 970,000 more joining a year later.
Those within scope must keep digital records of income and expenses, send HMRC a summary update for each quarter and complete a final declaration after the tax year ends, all through software that connects to HMRC’s systems. For those on the standard quarters, the first period runs from 6 April to 5 July 2026, with the first update due by 7 August 2026. HMRC has confirmed it will not charge penalty points for late quarterly updates in the first year, although the obligation to keep digital records applies in full from day one.
For landlords used to a single January deadline, the practical shift is less about volume than rhythm. Figures need to be captured as they arise rather than reconstructed from bank statements and paper receipts at year end.
Why spreadsheets and manual records fall short under the new rules
Spreadsheets are not banned under MTD, and many landlords will continue to use them in some form. The problem is the workflow built around them. A spreadsheet maintained once a year depends on memory, a shoebox of receipts and a disciplined owner. Maintained quarterly, under deadline, its weaknesses become more visible.
Manual record keeping tends to fail in predictable ways. Entries are made late or not at all. Receipts go missing between the letting agent’s statement and the next catch-up session. Costs are categorised inconsistently, or allocated to the wrong property when several are managed side by side. Rows get duplicated, deleted or overwritten, and files with names like “final_v3” multiply. Each quarterly update then requires someone to rekey totals from one place into another, which is exactly where transposition errors creep in. HMRC’s digital links rule sharpens the point: once figures exist in a digital system, they must reach the submission without being manually rekeyed, so typing totals from a spreadsheet into filing software breaks the rules unless bridging software preserves the link.
None of this means a spreadsheet automatically leads to trouble with HMRC. But errors that go unnoticed can flow into submissions, and correcting figures after filing is slower and more stressful than getting them right the first time. A clear, timestamped record of what was entered, changed and submitted also makes any later query far easier to answer. Under a regime built on digital records and regular updates, a dependable audit trail stops being a nice extra and becomes part of basic compliance hygiene.
Streamlining rental income and expense tracking for small portfolios
For landlords with one to five properties, the new requirements translate into a fairly short list of practical needs. Rent and costs should be recorded as they occur and kept apart property by property. Existing spreadsheets should be importable rather than retyped, ideally via CSV. Receipts need a digital home attached to the right expense. At the end of each quarter, the software should total everything into the summary HMRC asks for, let the owner review and approve it, and submit it through a secure connection to HMRC.
Recognition matters here. Only HMRC-recognised software can file through the official Making Tax Digital APIs, and recognised providers are listed publicly on GOV.UK, so marketing claims can be checked before anyone signs up.
One example of this newer breed of landlord-specific tool is Quarterwise landlord software, built around exactly this workflow. Its free tier covers one property with manual entry and CSV import, quarterly updates and the annual return, with no card required. A Pro tier at £99 a year, equivalent to £8.25 a month, adds unlimited properties, receipt capture and storage, AI-assisted categorisation with a review queue, per-property profit and loss and a live tax estimate. According to the provider, the software is HMRC-recognised under reference C2V6MT, submits through HMRC’s official APIs and hosts data on UK servers with encryption, logging every figure and submission with a timestamp.
The appeal for small portfolios is less about feature lists than about fit. Tools in this category strip out the general accounting machinery a landlord never uses and concentrate on the handful of tasks MTD actually demands, presented in plain language rather than accountancy jargon.
Short-term let hosts face an additional change alongside MTD. The furnished holiday lettings regime, which gave qualifying holiday lets a distinct tax treatment, was abolished from April 2025, bringing this income under the same property rules as other lettings, with the details depending on individual circumstances. For hosts using platforms such as Airbnb, Vrbo or Booking.com, the administrative bar rises: records need to show gross income with platform fees and other costs recorded separately, rather than a single net payout figure, and per-property records become essential where several lets are involved. Landlord-focused tools can support this discipline — Quarterwise, for instance, accepts earnings reports exported from the major platforms — but whatever the tool, the principle is the same: little and often beats a year-end reconstruction.
Choosing dedicated software without high accountancy costs
The market now ranges from full-service accountancy packages to lightweight landlord tools, and price alone is a poor guide. A sensible shortlist starts with compliance basics: recognised status on HMRC’s software list, digital record keeping, quarterly updates and the final declaration, plus a secure connection to HMRC. Beyond that, landlords should look for per-property separation, CSV import, receipt capture, export options for sharing records with an accountant, deadline reminders and transparent pricing.
It is worth being realistic about what software does not replace. For a straightforward portfolio of one to five properties, a recognised self-service tool can cover routine MTD compliance at a fraction of full-service accountancy fees, and most tools in this category are designed to work alongside an accountant where one is retained. Where affairs are more complex, for example with employment income, pensions, foreign income or partnership arrangements, professional advice remains the safer route, and the final declaration itself may need software that covers those additional income types.
The calmest response to the 2026 changes is early preparation rather than last-minute adjustment. Landlords should first check their qualifying income to see when the rules will apply to them, then establish a digital record-keeping habit well before their first quarter begins. Choosing recognised software that matches the size of the portfolio, and involving an accountant where affairs are complex, turns a regulatory shift into a routine. For most small landlords, the quarterly update then becomes what HMRC intends it to be: a short, regular task rather than a January ordeal.
