Hello everybody. I hope you will excuse any mistakes in English. I am a Greek American living in Greece for ... ever (almost). We moved back to Greece when I was only six. Now I just recieved a letter from my bank that I ought to fill in a w-9 form, because the bank needs to comply with FATCA. I looked the whole thing up in the internet, americans are affected in many countries by FATCA, but the greek banks are just starting to search for american persons among their clients. They don't look only for accounts for which an american passport was used. They are looking for "us persons" and this would include all those who were born in the States, even though they don't earn money in the States, or have actually lived in the States. These people are being asked either to fill in an IRS form (w-9) or to prove that they are not american citizens. By signing an w-9 form they actually confirm that they are "us residents for tax purposes. It's soooo complicated. But FATCA affects all Americans living permanently abroad, only, it is very schocking for dual citizens who didn't have a clue about FATCA and everything else. Although I think that the actual agreement between USA and Greece has not been signed yet, the banks have started searching and collecting information about US persons and asking them to sign the irs forms (I don't really know if this is actuallly legal). There is much on the net about FATCA and all kind of problems that it's been causing to americans abroad. Has anybody else been contacted by their bank? Do you know what we ought to do? A bank has told me to sign a W-9 form, another to sign the w-8 form.
