I am an air bnb host in London and have been hosting my flat since September 2021. I was only informed recently by a friend about the 90 day rule, that apparently you cannot rent your property or room for more than 90 days! I had no idea about this as this useless website has no reference to this issue at all.
Furthermore, I would like to know about the tax situation as again no information about this exists on here. Am I correct in thinking that in the UK, the first £7500 earned through airbnb is tax free?
