You may have seen in the newspapers that Airbnb will share data with HMRC about the earnings of hosts (those who let out property) on its UK platform in the years 2017/18 and 2018/19.

It is anticipated that HMRC will use this data to open enquiries into the tax affairs of individuals who have not declared letting income for 2017/18 and 2018/19. The deadline for opening an enquiry into a self-assessment return for 2018/19 is 31 January 2021, if the return was issued and submitted on time. The discovery rules allow HMRC to go back much further, potentially up to 20 years in some cases if the property income has not previously been reported.
