HMRC has significantly ramped up its focus on landlords, with tax investigations generating a record £107 million in 2024/25 alone. Over the last decade, the Let Property Campaign (LPC) and related compliance activities have secured between £373m and £570m in total, depending on how the figures are defined. While landlords represent just one part of HMRC’s compliance efforts, the yield has steadily grown — and the last year marks the sharpest increase yet.
The Headline: £107 Million Recovered in 2024/25
According to a Freedom of Information (FOI) response published in September 2025, HMRC collected £107 million from landlord tax compliance activity in 2024/25 — the highest annual figure on record. The same FOI revealed that the average tax recovered per disclosure hit £13,713, another record for the Let Property Campaign.
This signals that HMRC is not only recovering more overall but is also targeting higher-value cases, possibly using advanced data analytics and tighter third-party reporting (e.g., Land Registry, letting platforms).
Five Years in Review: The Numbers So Far
Unlike other areas of compliance, HMRC doesn’t publish a neat, year-by-year public table of “landlord-only” yields. Most of what we know comes from FOI requests, which differ in scope and definition. That’s why total figures vary across reports. Here’s a snapshot:
- 2019–2023: An FOI reported in 2023 showed the Let Property Campaign had generated ~£236.3m in its first 10 years (2013–2023).
- By May 2025: An independent tracker reported the campaign had secured ~£373.6m to date.
- 2024/25 alone: A separate FOI revealed a record £107m raised, bringing the campaign’s lifetime total to £570m if follow-on compliance is included.
Why the differences?
- Definitions matter: Some reports count only voluntary LPC disclosures, while others include additional penalties, interest, and follow-on investigations.
- Cut-off dates: FOIs are answered at different points in the year, so totals can shift.
- Revisions: HMRC may update or restate figures after compliance cases are finalised.
Context: Landlord Yields vs. HMRC’s Wider Compliance
While £107m in a year is significant, it is a fraction of HMRC’s wider compliance activity, which brings in tens of billions annually across all taxes. Still, landlords are firmly on HMRC’s radar because:
- Data matching is easier: Rental income is increasingly visible thanks to digital records, Land Registry data, and letting platform reports.
- More landlords are taxable: Recent changes, such as the withdrawal of full mortgage interest relief, mean more landlords owe tax even if their cash profits are low.
- Political focus: Rental housing is a hot topic, making compliance in this sector more visible.
Practical Takeaways for Landlords
- If you’ve received an HMRC “nudge letter” or have undeclared rental income, don’t ignore it. The Let Property Campaign is still the most favourable route for voluntary disclosures.
- Expect increased scrutiny. HMRC has invested heavily in compliance teams and data analytics, and landlords are one of its key targets.
- Voluntary disclosure is cheaper. Waiting for HMRC to catch you often leads to higher penalties and interest.
Conclusion
The past five years have seen HMRC steadily increase its landlord-focused tax recovery, culminating in a record £107m raised in 2024/25. With lifetime totals now quoted anywhere between £373m and £570m, the direction of travel is clear: landlords are a growing source of compliance revenue, and HMRC has no plans to ease off.
For landlords, this means one thing: get your tax affairs in order before HMRC does it for you.
