Thank you Martin, I didn't realize FATCA was bilateral, thought it was a one way street hence all the huffing and puffing by the EU towards the US not signing up to CRS. Yes, agreed it is no coincidence that the offshore banks have increased in PR due to not having to comply with the CRS for now. EPB moved there end of last year from St. Vincent. But what you are saying is home country tax offices can go on fishing expeditions. The bank currently has no obligation to comply, but you are saying the US IRS could request EPB to hand over my W8 and check my account? Then hand that over to home country tax office. So it sounds that home country tax office would have to approach the US IRS and make a request along the lines of we want you to give us all details of account holders from our country for every bank in Puerto Rico. That's a helluva big request. Has this ever happened?
