Don't want to dripfeed but also don't want to give away too much! I have just had to fess up and pay tax on a property my ExH and I owned jointly and rented out some years ago. I owned up as I couldn't sleep knowing I owed the money and felt v guilty. Historically he always refused to fill in tax returns and wouldn't let me fill one in either - he was very controlling and abusive and I was genuinely frightened of him and so I did what he told me. I have just had to pay a huge tax bill and fine of over £3k - obviously what I owe HMRC and so I do not begrudge paying them. What irks me is that he has not owned up to his share of the rent - would IBU to dob him in?! Or is this just sour grapes that I am disguising to myself as being a good citizen?
