What is Let Property Campaign?

The Let Property Campaign is an HMRC voluntary disclosure scheme for residential landlords who have undeclared rental income or have not fully reported their UK property income. It gives eligible landlords an opportunity to voluntarily disclose previously undeclared income and bring their tax affairs up to date.

Making a voluntary disclosure to HMRC can help you address unreported rental income, correct past tax returns and understand any tax, interest and penalties that may be due. Acting voluntarily may also result in more favourable penalty treatment than waiting for HMRC to identify the issue through an enquiry or investigation.

At Legend Fusions, we provide professional Let Property Campaign support, from reviewing your rental income and expenses to preparing your disclosure and communicating with HMRC. Our structured approach helps landlords resolve their tax compliance issues accurately and efficiently.

Risks of Not Disclosing Rental Income

Failing to declare rental income to HMRC can result in serious financial and compliance consequences. HMRC has advanced data-matching systems, meaning undeclared income can be identified even years later, often leading to higher liabilities and enforcement action.

This may
result in:

  • HMRC may open a formal enquiry into your tax affairs and review multiple years of rental income and records.
  • Penalties can be charged based on the level of error, behaviour, and how late the disclosure is made.
  • Interest is applied on unpaid tax from the original due date until the liability is fully settled.
  • HMRC may extend investigations into earlier tax years where inconsistencies are found.

What the Let Property Campaign Covers?

Most disclosures require several years to be rebuilt from records never prepared for later challenge. We take the position from assessment to submission.

  • Disclosure of undeclared or incorrectly reported rental income
  • Preparation of backdated returns for affected tax years
  • Review of allowable property expenses and deductions
  • Correction of previously unreported or underreported income

I can't recommend Legend Financial and Tax Advisers enough. I worked with Ghazaleh, who was extremely helpful and made the whole experience stress-free. What really stood out was how quickly she handled everything — my tax returns were submitted within a week, which I understand is far quicker than the month or more it takes at many other places. She also did a fantastic job of walking me through the MTD requirements in a way that was easy to understand. Brilliant service all round.

A let property campaign disclosure is the formal process of reporting previously undeclared or incorrect rental income to HMRC, including calculation of tax, interest, and penalties.

You must review your rental income history, calculate tax owed, and submit a voluntary disclosure through HMRC’s Let Property Campaign or with help from a tax adviser.

It is for UK and overseas landlords, including accidental landlords, property investors, and individuals with undeclared rental income disclosure requirements.

HMRC may open an investigation, charge penalties and interest, and extend the review period for up to 20 years in serious cases of non-disclosure.

Let Property Campaign penalties depend on behaviour, timing of disclosure, and whether the error was careless or deliberate.
