Understanding the HMRC Let Property Campaign
The HMRC let property campaign is a voluntary disclosure option for landlords who haven’t reported all of their rental income. It applies to residential property income across the UK, including single lets, HMOs, shared housing, and short-term rentals like Airbnb. Non-resident landlords earning rental income from UK properties can also use the scheme.
Making a let property campaign disclosure means telling HMRC about undeclared income, calculating what’s owed, and paying it, often with lower penalties compared to a full investigation. Unlike an HMRC inquiry, this process gives you control and clarity from the start.
You begin by notifying HMRC of your intent to disclose. After that, you have 90 days to gather records, calculate any liabilities, and submit your full disclosure. The campaign generally covers up to six years of unreported income, though in more serious cases, HMRC can look back as far as twenty.
Lanop handles every part of this for you, with strict confidentiality and expert attention to detail. We make sure your figures are accurate, expenses are fully claimed, and your disclosure under the let property campaign is structured to reduce penalties. The result is peace of mind, legal compliance, and often major savings.
Challenges Landlords Face
- Not knowing how far back HMRC can investigate.
- Missing records for older tax years.
- Confusion over allowable expenses.
- Fear of HMRC contact and penalties.
- Time pressure during the 90-day disclosure period.


Why Acting Now Saves You Money
Waiting to deal with undeclared rental income almost always leads to higher costs. The HMRC let property campaign is designed to encourage landlords to come forward voluntarily, offering reduced penalties in return. Those who disclose before being contacted by HMRC usually face penalties between 10 and 20 percent of the unpaid tax. In contrast, if HMRC discovers the issue first, penalties can rise to 100 percent or more.
The let property campaign HMRC process also puts you in control. Once registered, you get 90 days to gather your documents, calculate your liabilities, and submit your let property campaign disclosure. Ignoring it risks a formal investigation, greater penalties, and the loss of control over the timeline.
Disclosing early allows us to maximise your expense claims and lower the tax owed. Many landlords are genuinely surprised at how much they save once valid deductions are included.
At Lanop, we’ve helped clients significantly reduce penalties through well-prepared, fully compliant disclosure under the let property campaign. We understand what HMRC expects, and we present your case clearly to avoid unnecessary scrutiny. Acting now gives you leverage, certainty, and a better financial outcome.
Challenges Landlords Face:
- Misunderstanding the disclosure process.
- Fear of disclosing errors from multiple years.
- Difficulty in calculating the correct tax owed.
- Underestimating the penalties HMRC may apply.
- Waiting too long and missing the chance for reduced penalties.


The Disclosure Process in Practice for Let Property Campaign
The HMRC let property campaign process is simple when handled by experts, but costly mistakes can happen if you go it alone. At Lanop, we manage every step with precision, ensuring your disclosure is accurate, compliant, and positioned to secure the lowest penalty possible.
It starts with notifying HMRC of your intention to disclose. Once registered, you’ll receive a 90-day window to prepare and submit your full let property campaign disclosure. During this time, we help you collect all necessary records, including rental income, supporting documents, and every allowable expense you’re entitled to claim.
Next, we calculate the tax owed, along with interest and reduced let property campaign penalties, ensuring the figures are fair and defensible. Once the disclosure is ready, we submit it on your behalf and assist in arranging payment, whether as a lump sum or through a Time to Pay agreement.
By managing the entire process, we reduce your stress, protect you from costly errors, and help you achieve a compliant outcome that satisfies let property campaign HMRC requirements, with the lowest legal liability.

FAQ
Accountants for lET pROPERTY cAMPAIGN
What is the HMRC Let Property Campaign?
It’s a scheme HMRC launched to let landlords come forward and declare rental income they’ve missed in previous years. The idea is simple: tell them before they find out, and you’re usually met with lower penalties. The HMRC let property campaign is much less stressful than going through a full investigation later on.
How far back can HMRC go?
Normally, they’ll look at the last six years. But if they suspect deliberate evasion, they can extend that period up to 20 years. With the let property campaign HMRC, acting early helps keep things within that six-year range and stops things from escalating into something more serious.
What happens if HMRC contacts me first?
You’ll lose the option to make a voluntary disclosure. That means higher penalties and less flexibility in how things play out. The government let property campaign only works if you approach HMRC before they contact you. Once they’ve opened a case, you’re looking at formal procedures and more scrutiny.
Can I do the disclosure myself?
Technically, yes. But it’s a risky move unless you’re confident in your numbers. Hiring a let property campaign accountant means you’re far less likely to make costly errors. You also have someone who knows how to structure the disclosure in a way HMRC accepts without unnecessary questions or pushback.
What if I rent through Airbnb?
Even if you’re just letting out a room a few weekends a year, that income still counts. Under the UK let property campaign, Airbnb income must be disclosed like any other rental. HMRC has access to third-party data, so chances are, they already know it’s happening, better to declare it first.
