The first phase of Making Tax Digital (MTD) for Income Tax Self Assessment went live on 6 April 2026, bringing landlords with qualifying income over £50,000 into scope – an estimated 118,000 landlords in the 2026/27 tax year alone. Thresholds reduce to £30,000 from April 2027 and £20,000 from April 2028, eventually pulling the majority of the UK’s private landlord base into the regime.

This shift is more significant than it sounds. A large proportion of landlords still do not operate like businesses.

Many are accidental or part-time investors, relying on spreadsheets, inboxes, or even boxes of receipts, which are handed over in a rush at the end of the tax year. MTD removes all of that flexibility. Records now need to be complete, accurate and maintained continuously.

For accountants, this is less a compliance change and more a behavioural one.

Where the compliance gaps will appear first

The earliest challenges are already emerging in data organisation. Landlord finances are rarely held in one place – income may sit with letting agents, expenses across bank feeds and invoices, with adjustments handled manually. Pulling that together once a year was manageable, but doing it quarterly exposes every single gap.

In practice, this means accountants are seeing recurring issues: missing transactions, duplicated costs, and inconsistent categorisation. These are not new problems, but MTD brings them to the surface earlier and more often.

There is also a clear awareness gap. While HMRC reports near-universal awareness of MTD among agents, landlord understanding is far less developed. Recent survey data suggests nearly half of landlords lack confidence in their understanding of MTD, with a significant proportion not confident at all.

Adoption is also uneven. Landlords with larger or more complex portfolios tend to engage quickly, often recognising the operational benefits of better systems. Smaller landlords are more likely to delay, either underestimating the change or assuming timelines may shift again. This creates a risk later in the year, when less-prepared clients enter the system at once and require significant clean-up.

Building a workable quarterly rhythm

The move to quarterly reporting introduces a new cadence for both accountants and clients. Instead of a single year-end deadline, there are now regular cycles of data collection, review and submission.

Handled well, this reduces pressure. Regular check-ins replace the last-minute scramble that defines many landlord engagements today. Handled poorly, it simply spreads the same inefficiency across four deadlines.

The essential difference is structure. Clear expectations around what clients provide, when they provide it, and how it is reviewed will be essential. Informal processes that worked under annual reporting quickly break down under a quarterly model.

Working with agents, not around them

One of the more overlooked dynamics in MTD is the role of letting agents. A significant proportion of landlords rely on agents to manage rent collection and expenses. In effect, agents already hold much of the financial data required for compliance. The challenge is that they are not tax specialists, yet are increasingly fielding questions about MTD.

This creates both friction and opportunity. Where data remains siloed, accountants face additional reconciliation work. Where systems integrate effectively, much of the manual effort disappears.

Around half of landlords use a letting agent for their most recent letting, meaning a significant proportion of the underlying financial data already sits outside the accountant–client relationship.

Recent moves in the software market reflect this shift – direct integrations between landlord accounting platforms and major letting agent client accounting systems are beginning to eliminate the manual reconciliation layer entirely.

Practices that align more closely with agents – understanding how data is captured and ensuring it flows directly into accounting systems – will reduce duplication and improve accuracy. Increasingly, MTD is not just a relationship between accountant and client, but part of a wider ecosystem.

MTD in a broader regulatory shift

MTD does not sit in isolation. It arrives alongside the Renters’ Rights Act, which will introduce phased changes to tenancy management and compliance requirements from May 2026.

Taken together, these changes are raising the bar for landlords. For some, particularly those operating at smaller scale, this is prompting a rethink – whether that means restructuring portfolios or exiting the market altogether.

At the same time, a new generation of investors is entering with a more commercial mindset, treating property as a business from the outset.

For accountants, this shift is important. The client base is changing, and expectations around structure, reporting, and advice are increasing.

Practical steps for accountancy

The starting point is a clear view of current client processes. How is income recorded? Where are expenses tracked? What role do agents play? Identifying these flows early makes it easier to design a workable quarterly approach.

From there, practices should establish defined protocols: what data is required, when it is submitted, and how it is checked. Consistency here is critical to avoiding repeated corrections.

Software choice also matters. The number of MTD-compatible products has grown rapidly, but not all offer the same level of reliability or integration. Prioritising established platforms that align with both client and agent workflows will reduce risk over time.

Finally, combining MTD onboarding with broader regulatory guidance, including Renters’ Rights, allows accountants to position themselves as a central point of support, rather than just a compliance function.

Turning compliance into opportunity

MTD is often framed as an administrative burden. In practice, it creates the conditions for a more structured and valuable client relationship.

With better data, maintained throughout the year, accountants gain more visibility. Quarterly reporting becomes a natural point for discussion, not just on compliance, but on performance, costs, and planning.

That shift has clear commercial implications. More frequent touchpoints support a move towards fixed-fee or retainer-based models, reduce the cost of year-end clean-up, and create opportunities for higher-value advisory work.

For landlord clients, the transition may feel disruptive. For accountants, however, it is an opportunity to standardise processes, strengthen relationships, and move closer to the centre of their clients’ financial decision-making.
