We are landlords with a small buy-to-let portfolio and also rent out a room in our own house via Airbnb. If we include this income with our total property income on our tax returns, can we use our rent-a-room exemption to offset some rental income?

Arthur Weller replies:
There is a special place on the UK property pages to record rental income eligible for rent-a-room relief. So you should keep the two sets of rental income separate on the self-assessment return, and consequently claim the renta-room exemption.
