Hey, firstly I would stop being paranoid, there's no need for that whatsoever.
Now, the easiest way to live peacefully is to move out to a country that's not part of the EU, there are many, literally many countries you can go to, I love Mexico and Thailand is not bad either, both super cheap to live there, but there are many others, your decision (don't tell anyone where you are going)
No one is going to come looking for you, I guarantee you that 100% and as far as your money goes, keep it in different EMIs, if you want to continue being super︀ paranoid, then just open a company account where the beneficiary is not publicly disclosed.
Honestly you have nothing to worry, I could get into a more detailed explanation, I know︁ quite a bit about the subject, just leave and relax.
Just for the record I︂ do agree that women are the worst when it comes to "nailing a guy", the︃ fact is that many tax agents accuse at least 50% of the time people that︄ have not committed any tax crime, look at the stats and see for yourself. They︅ will threatened you first hoping that you get scared and pay them, the fact is︆ that if you go to court and fight, you have a great chance of winning.︇
If they haven't frozen your account just move the money and leave the country, no︈ need to stay there getting scammed (use a bridge EMI between your current account and︉ the final EMIs)
By the way, the CRS reports on a yearly basis, they're not︊ going to report the last 3, or the last 8 or 20 years, no way,︋ it's different if the tax authorities investigate you, then they'll go back as far as︌ they legally can, remember there is a statue of limitations in almost every country in︍ the world
Honestly, relax and just move to a none European country, you don't want︎ to live in Europe anyway, worse place to live at the moment, not to mention️ the crazy brutal taxes.
And no, they can not send letters to every bank in the world, they can only contact an specific bank in an specific jurisdiction if they know you are living and banking there, so stop being paranoid about all those ideas that come to your mind, wish we could have a beer so you start relaxing and enjoying life.
Hope that helps...
