The Let Property Campaign is HMRC’s disclosure facility for individual landlords who have not declared all of their rental income. It allows you to bring your tax affairs up to date voluntarily, usually with lower penalties than if HMRC opens an enquiry first.
Who it is for
The campaign is aimed at individuals who let residential property in the UK or abroad and have undeclared income or gains. It can apply whether you let a single flat, several properties, a room in your own home above the Rent a Room limit, or holiday accommodation. Companies and trusts cannot use the campaign but may be able to disclose through other HMRC routes.
Why act now
HMRC receives information from letting agents, deposit protection schemes, online platforms, mortgage lenders and the Land Registry, and regularly writes to landlords it believes have not declared their income. If HMRC contacts you first, penalties are higher. A voluntary disclosure shows good faith, keeps penalties to a minimum and gives you certainty.
How the process works
- We notify HMRC on your behalf that you intend to make a disclosure.
- HMRC issues a disclosure reference. You then have 90 days to submit the disclosure and pay what is due.
- We calculate the income, allowable expenses, tax, interest and penalties for each year.
- We submit the disclosure and agree a payment arrangement with HMRC if needed.
How far back you need to go
The number of years depends on the reason the income was not declared. Where reasonable care was taken, HMRC can generally go back four years. This extends to six years for carelessness and up to twenty years where the failure was deliberate. Establishing the correct behaviour is one of the most important parts of the disclosure, as it affects both the years covered and the penalty rate.
