HMRC is tightening its grip on landlords, and the clock is already ticking. Making Tax Digital for Income Tax (MTD for IT) represents the biggest shake-up to self-assessment in decades — and most landlords still don't fully understand what's coming.
What Is Making Tax Digital and Why Does It Matter?
Until recently, landlords and sole traders could keep paper receipts, use spreadsheets, and submit a single annual self-assessment return. That era is ending. From April 2026 onwards, HMRC is requiring a fundamentally different approach to record-keeping and reporting.
Under the new rules, paper receipts are no longer acceptable. Spreadsheets are out. Instead, landlords must use HMRC-recognised accounting software to maintain fully digital records. More significantly, rather than filing one annual return, you will now need to submit four quarterly updates plus a final end-of-year declaration — five submissions in total, compared to the previous single filing.
Why is HMRC doing this? The answer is straightforward: the taxman believes there is a £5 billion tax gap — the difference between what is collected and what should be collected. HMRC estimates that small businesses, including landlords and sole traders, account for 60% of that gap, largely due to lost receipts, estimated income figures, and disorganised record-keeping. Making Tax Digital is their mechanism for closing it.
The Thresholds, Timelines and Penalties You Need to Know
MTD for IT applies to landlords who own property in their personal name (not through a limited company), combining their rental income with any sole trader income. The rollout follows a phased threshold approach:
- April 2026 — If your combined income exceeds £50,000, you must comply immediately.
- April 2027 — The threshold drops to £30,000.
- April 2028 — It drops again to £20,000, at which point virtually every landlord with even a couple of properties will be captured.
HMRC has already begun sending letters to those it believes should be complying from April 2026, so do check your post carefully.
For jointly owned properties, each owner counts their share towards their own threshold — so a £40,000 rental income split equally means £20,000 each, which counts towards your individual total.
The penalty system works similarly to driving licence points. Each missed quarterly submission earns one penalty point. At four points, you receive a £200 fine, with an additional £200 for every missed submission thereafter. Points only reset after 12 consecutive months of clean submissions. Late payments attract interest from day one, plus a 2% penalty at 15 days late and another 2% at 30 days. The one piece of good news: HMRC has confirmed there will be no penalties in the first year as landlords adjust to the new system.
It is worth noting that the quarterly updates are not quarterly tax returns — they simply report your income and expenses for that period. Your actual tax payment date remains the same as under self-assessment. The updates are also cumulative, so anything missed in quarter one can be included in quarter two.
Five Practical Steps to Get Yourself Ready
Rather than waiting until the deadline forces your hand, we'd strongly recommend taking action now. Here are five things every landlord should be doing:
-
Open a dedicated bank account for your rental business. Mixing personal and property finances is the single biggest source of confusion when it comes to digital record-keeping. A separate account integrates cleanly with MTD software and will save you hours of administrative headache.
-
Choose and start using HMRC-recognised accounting software today. The learning curve is the hardest part — the sooner you begin, the easier the quarterly submissions will feel.
-
Talk to your accountant about fees and process. Four additional quarterly submissions per year represents real extra work, and you want to agree on costs upfront rather than face a surprise bill.
-
Start preparing even if you're below the threshold. If you expect to cross the £30,000 or £20,000 threshold next year, you'll need a full year of digital records already in place when compliance kicks in. This takes time to set up properly.
-
Align your accounting year with the tax year (6th April to 5th April). If your year-end doesn't currently match, speak to your accountant about transitioning — overlap relief is available to soften any short-term tax impact.
Is This an Opportunity in Disguise?
Property Mark, the letting agency regulatory body, has warned that MTD will push some landlords out of the market entirely. That is genuinely likely — but for those who stay, it creates a real opportunity. Fewer landlords means reduced supply of rental properties, which historically drives rents upward.
There is also a structural advantage for landlords who embrace the change. Treating your portfolio as a proper business — with monthly visibility over income and expenditure — puts you in a far stronger position than the traditional shoebox-of-receipts approach.
For landlords considering whether to hold property in a limited company rather than personally, MTD is one more factor worth weighing up. Properties held in a limited company fall outside the MTD for IT rules entirely. If you haven't yet purchased and are weighing up your ownership structure, 1st Formations offer a dedicated Property SPV service that makes setting up a limited company for property investment straightforward and cost-effective.

Act Now, Not Later
Making Tax Digital is not a distant concern — for landlords earning above £50,000 combined income, it is already here. For everyone else, the deadlines of April 2027 and April 2028 will arrive faster than expected. The landlords who prepare now will find the transition far less painful than those who leave it to the last minute.
