@luisHK Yes you can do contrary to what @dw31583 is saying that but the key is to stay under the radar. You also need to avoid arousing suspicion. Living the high life while not declaring is a great way to get audited.
Note that while although tax info sharing is widespread these days, not every jurisdiction has signed on and those that have, a good number of them are taking really long to roll out the changes.
Also, enforcement is not that strong in certain jurisdictions. Know your country(counterparty risk). My 2 cents.
I was talking about the italian scheme where one pay 100k euro a year flat fee and than don't need to pay taxes on their overseas income, nor even to declare their overseas assets and income.
One doesn't enrol in such a scheme to live miserably, nor is supposed to.
Otherwise I agree with you and share your impressions about the AEOI, while it makes confidentiality more complicated, it doesn't seem to be as bad as DW implies every other post, and it is not clear some of the signatory countries will ever play ball.
