Has anyone had any experience with the above HMRC campaign? We've been renting our property while abroad out to a relative- we're not making a profit and they are only paying the equivalent of the mortgage each month. Stupidly we didn't think we needed to inform HMRC as we weren't making a profit, but after a chat what a friend last week we realise now that that's not the case. We've spoken to HMRC to declare this and have got an accountant to help us with the self assessment for this last tax year and then to declare the 2 years prior to this. Our accountant is really relaxed about it, says it's a common mistake and that HMRC are not interested in coming down hard on people who make mistakes like this if they come forward. And as we have approached HMRC rather than them finding out another way then the penalties will be less severe. We can afford to pay what we may owe, that's not a problem. But despite knowing al this I still feel really anxious about it all (suffer with anxiety so finding it hard to be rational right now!), so wanted to ask if anyone had any experience with this and what the outcome was?
