Let Property Campaign London

What Is the HMRC Let Property Campaign?

The Let Property Campaign (LPC) is an HMRC disclosure facility that allows individual landlords (including those with property in the UK or abroad) to tell HMRC about undeclared rental income and settle any tax, interest, and penalties. The campaign is specifically designed for residential property landlords and individual landlords renting out residential property.

It does not cover non residential properties such as commercial spaces, shops, or garages. The purpose of the campaign is to encourage landlords to disclose income and report previously undisclosed taxes related to letting income. By using the LPC, landlords can disclose rental income and previously undisclosed taxes voluntarily, which offers the benefit of lower penalties compared to if HMRC discovers the unreported income themselves. It’s designed to encourage voluntary disclosure with more favourable penalty terms than if HMRC finds the issue first.

The campaign is aimed at, for example:

Landlords letting out a single property
Those with multiple residential properties
Accidental landlords (e.g. inherited or former home now rented)
Those renting out rooms in their own home (beyond the Rent a Room limit)
Non-resident landlords with UK rental income

If HMRC contacts you before you disclose, the penalties are usually higher and you lose some of the protection and flexibility that the Let Property Campaign can offer.

1. Specialist Let Property Campaign Knowledge

We focus specifically on rental disclosure cases and understand how HMRC approaches the Let Property Campaign, what they expect in a disclosure, and how to present your figures clearly and accurately. Our expertise covers every aspect of the disclosure process, ensuring clients comply with HMRC requirements and minimize penalties. We help you make the most of the disclosure opportunity provided by HMRC, which is a time-limited chance to voluntarily report undeclared rental income and resolve tax issues efficiently.

Whether you live in London, elsewhere in the UK, or overseas with a London property portfolio, our team can help. We regularly deal with:

London flat and house landlords
Landlords who have earned income from letting property in London or overseas
“Accidental” landlords who rented out a former home
Non-UK residents who own and let London property

3. Minimising Penalties & Stress

Handled correctly, the Let Property Campaign can:

Reduce penalties where disclosure is unprompted and complete
Help you avoid more serious HMRC investigations in the future
Give you peace of mind that your affairs are fully up to date

Failing to disclose voluntarily may result in HMRC applying the maximum penalty, as the penalty rate depends on the quality and timing of your disclosure.

Our job is to prepare a full, honest, and structured disclosure so HMRC has confidence in the figures presented.

Our Step-by-Step Let Property Campaign Process

We handle the entire process from start to finish. Here’s how it works:

Step 1: Free, Confidential Initial Discussion

We start with a no-obligation call to:

Understand your property situation and history
Identify the years where rental income was not fully disclosed
Identify any outstanding liabilities and undisclosed income that may need to be reported to HMRC
Discuss your concerns (e.g. letters already received from HMRC)

Everything you tell us at this stage is confidential and purely for advice.

Step 2: Registering for the Let Property Campaign

If you decide to go ahead, we:

Notify HMRC that you want to make a disclosure under the Let Property Campaign
Obtain your Disclosure Reference Number (DRN) and Payment Reference Number (PRN)
Receive a notification acknowledgement from HMRC, which marks the start of the 90-day period to submit your full disclosure and payment
Confirm HMRC’s deadlines for submitting your full disclosure and payment

Step 3: Collecting & Reconstructing Your Rental Figures

We help you gather and reconstruct the information needed to calculate the undeclared rental profit, including:

Rental income received (bank statements, letting agent statements, tenancy agreements)
Calculating total rental income and received rental income for each tax year, ensuring all income is accurately disclosed for the relevant period
Allowable expenses (repairs, insurance, service charges, mortgage interest where applicable, agent fees, etc.)
Empty periods, part-year lettings, and joint ownership details

Rental profits are determined for each tax year by deducting allowable expenses from the total rental income received.

Where records are missing, we work with you to reconstruct reasonable and defensible estimates in line with HMRC expectations.

Step 4: Calculating Tax, Interest & Penalties

Once we have full figures:

We calculate the additional income tax due for each affected year
We calculate statutory interest
We agree an appropriate penalty level, taking into account whether the disclosure is unprompted, your behaviour, and cooperation with HMRC
We determine your total tax liability, including any underpaid tax and the amount of paid tax to date

You may owe tax for previous years, and this will be reflected in your assessment tax return.

We’ll explain all calculations in plain English so you know exactly what you’re paying and why.

Step 5: Preparing & Submitting the Disclosure

We then:

Prepare your formal Let Property Campaign disclosure
Make sure the narrative explains clearly how the error arose and the steps you have taken to correct it
Advise if separate disclosures are required, for example, where there are multiple landlords or properties involved
Submit the disclosure and coordinate payment to HMRC using the correct reference

We aim to ensure your disclosure is complete, consistent, and professionally presented to reduce the risk of follow-up queries.

Step 6: HMRC Response & Finalising Your Position

If HMRC has questions after receiving your disclosure, we:

Deal directly with HMRC on your behalf
Provide any additional information requested
Work towards closing the disclosure with no further action once everything is agreed

The vast majority of disclosures are accepted by HMRC once all required information is provided.

Common Situations We Help With

Our Let Property Campaign team in London regularly assists landlords who:

Forgot to declare rental income when they first started letting
Thought rental income was covered by allowances but later realised it was not
Inherited a property and started renting it out without updating their tax returns
Rented out their home temporarily when working abroad or moving in with a partner
Have multiple properties with years of partially or completely undeclared income
Received a “nudge letter” from HMRC suggesting they may have undeclared rental income

HMRC may use land registry data to identify landlords with undeclared rental income.

Whatever your situation, it is almost always better to disclose voluntarily than to wait for HMRC to open an enquiry.

Why You Should Act Now

Delaying can:

Increase the amount of interest, penalties, and unpaid taxes
Risk HMRC opening an enquiry before you disclose
Prolong the uncertainty and stress of having undeclared income and outstanding liabilities

Acting now allows you to:

Approach HMRC through a formal, recognised campaign
Show that you are taking reasonable care to correct the position
Draw a line under past issues and move forward

If you have undeclared rental income, the Let Property Campaign is the route HMRC expects most individual landlords to use. There are other disclosure facilities for different types of income, but for residential landlords the LPC is usually the most appropriate.

The number of years depends on your specific circumstances, such as whether the omission was a genuine mistake or deliberate. HMRC can, in some cases, look back up to 20 years. We’ll advise you on a reasonable period and ensure your disclosure is complete and defensible.

The company itself can be incorporated quickly, but proper planning, documentation and funding typically take longer. The important part is getting the structure right, not just forming a company.
