According to The Times of Israel, American ex-pats in that country are now facing dual threats from the IRS:
The US is gearing up to reach out to American citizens abroad that it believes have not paid their fair share in taxes. Israel is set to begin enforcing new US rules on reporting the existence and activities of accounts in Israeli banks held by American citizens or dual-citizens. That is in addition to a marked increase in audits and investigations of American ex-pats in Israel by the US — to the extent that a rumor has surfaced that the Internal Revenue Service has opened a “branch office” in Israel to handle the volume of audits.
Judging by the comments so far, Brockers should find a receptive audience. A good outreach opportunity.
