I am renting out my house as we can't sell, we are not making nay money in fact we are loosing as it is to my sister and she can't afford to cover the mortage , so there is a shortfall of about fifty quid a month. We are happy to subsidise by that amount as we know the house will be looked after and there is flexibility over putting the house back on the market.
How do I declare her rent for tax purposes, am I right in thinking that as we are not making any money we will not have to pay tax?
