I recently found out that DP has approximately £2k per month in rental income, both in the UK and overseas, none of which he has ever declared for tax purposes. This has been going on for several years. I consider this tax evasion and I would be struck off the professional body to which I belong if this were uncovered and I were living with him/married to him.
This isn't a "relationship" question (there are other issues) but a genuine AIBU or naive, unrealistic and judgmental as he thinks I am. He says "everybody does it if they can". I disagree. I cannot easily ask anyone in RL so thought I'd ask MNetters.
