If you have rental income that hasn’t been declared to HMRC whether from UK or overseas property you’re not alone.
It’s a situation many landlords find themselves in, often due to changes over time or misunderstandings with managing agents rather than deliberate action.
HMRC’s Let Property Campaign (LPC) provides an opportunity to bring your tax affairs up to date, often with reduced penalties compared to being contacted first.
However, the process can be complex, particularly where records are incomplete or the position spans multiple years.
We take a look at how the campaign works, why timing matters, and how the right support can make a significant difference to the outcome.
What Is the Let Property Campaign?
The Let Property Campaign is an HMRC initiative that allows landlords to voluntarily disclose previously undeclared rental income.
It applies to:
- Individuals renting out residential property in the UK or overseas
It does not apply to:
- Commercial property
- Trusts
- Company-owned properties
Once you notify HMRC of your intention to disclose, you typically have 90 days to calculate and report:
- The unpaid tax
- Interest
- Any applicable penalties
Penalties are generally lower for voluntary disclosures than for cases where HMRC opens an enquiry first.
Why Acting Early Matters
HMRC continues to increase its focus on property income, using data from a range of sources including:
- Tenancy deposit schemes
- Letting agents
- Online platforms such as Airbnb
Where HMRC identifies undeclared income before you come forward, penalties can be significantly higher.
In some cases ranging from 10% to 200% of the tax due, depending on the circumstances.
By contrast, voluntary disclosure through the Let Property Campaign can reduce penalties substantially, and in some cases to very low levels.
Delaying action can also increase the likelihood of a formal enquiry, which can be more time-consuming and stressful to resolve.
How We Support Landlords
For many landlords, the challenge is not just the disclosure itself, but understanding what needs to be included and how to present it correctly.
We support clients across Kent and the wider South East with:
HMRC Liaison

Tax Review and Calculations
