What is the HMRC Let Property Campaign and how do I use it?
The HMRC Let Property Campaign (LPC) allows residential landlords with undisclosed rental income to voluntarily regularise their tax position at lower penalties (typically 0-30%) than if HMRC discovers the income first (30-100%). You notify HMRC of your intention to disclose, then have 90 days to submit full disclosure and payment.
Full answer
The Let Property Campaign (LPC) was launched by HMRC in 2013 and has remained open as an ongoing voluntary disclosure facility. It is aimed specifically at individual residential landlords who have rental income from UK or overseas property let to private tenants that has not been properly declared on their Self Assessment tax returns. Using the LPC is a two-stage process. Stage 1 -- Notification: you notify HMRC online at GOV.UK that you intend to make a disclosure. HMRC acknowledges and gives you a unique reference number. Stage 2 -- Disclosure: within 90 days of notifying, you must submit a full disclosure of all undisclosed rental income, the resulting tax owed (Income Tax plus any unpaid Class 2/Class 4 NI if self-employed), interest on the unpaid tax, and a penalty. Why use LPC rather than waiting: penalties under voluntary disclosure via LPC are typically in the range of 0-30% of the additional tax due (depending on the period of underpayment and whether the failure was careless or deliberate). If HMRC opens an enquiry or investigation first -- using data from the Valuation Office Agency, Land Registry, letting agents required to report under the OECD DAC7 rules, or credit reference agencies -- penalties rise to 30-100% of the tax owed, and HMRC may pursue criminal prosecution in serious cases. The LPC does not cover: business or commercial premises (use another HMRC disclosure facility); furnished holiday lettings that are taxed differently; deceased estates with rental income (use the Estate Accounts disclosure service). The LPC can cover multiple previous tax years -- there is no formal statutory time limit on how far back you need to disclose, but in practice HMRC typically focuses on the last 4-6 years for careless errors (20 years for deliberate non-disclosure). Any disclosure should be accurate and complete -- submitting an incomplete LPC disclosure that HMRC later identifies as underreported may lead to a harsher penalty than if you had simply waited for an enquiry.
