In the latest development in what is becoming a fast-moving international story concerning the bank accounts of tens of thousands of "accidental Americans" living outside of the U.S., it has emerged that the Dutch Banking Association has posted an animated video on the home page of its website in which it warns such clients of the need to get their U.S. Social Security numbers – if they don’t wish to lose their Dutch bank accounts.

The head of the French Banking Federation has formally warned France's finance minister that the country's banks may be forced to close as many as 40,000 bank accounts by the end of the year, owing to problems these banks have in complying with the U.S. tax information reporting law known as FATCA.

 The U.S. Internal Revenue Service said on Wednesday that it "will not challenge" the claiming of foreign tax credits against certain controversial payments that potentially thousands of American expatriates resident in France have been paying for years, and noted that taxpayers who wish to file a claim for refund of U.S. tax with respect to a foreign tax credit have 10 years after the "due date for filing the return" in question in which to do so.

In a development that is being seen by American expat groups in France as a major win, the U.S. Internal Revenue Service has admitted in a U.S. Tax Court that it had wrongly collected millions of dollars of tax from France-resident American citizens, ending a years-long legal saga that could see millions of dollars paid to U.S. expats who have lived in and been filing tax returns from France, in the form of refunds.

 American expats who have been calling on governments across Europe – and on the EU itself – to rally on their behalf against what they say is the unfair burden of being expected to comply with the U.S.’s Foreign Account Tax Compliance Act have been reacting with disappointment today to a letter from a key EU politician that they say shows their struggles still aren’t being acknowledged.

Tax industry professionals readily admit that they can’t recall when the U.S. tax obligations of an unborn baby American ever received anything like the coverage that has been devoted in recent weeks to the as-yet-un-named baby boy who was born a few hours ago to Britain’s Prince Harry and his American wife, Meghan.

The Accidental Americans Association, a Paris-based group that campaigns for fairer treatment for those who left the U.S. as babies or never lived there but who say they are nevertheless burdened by unfair U.S. tax obligations, has launched what it calls a "major lobbying campaign" to educate American lawmakers of these "accidentals'" plight.
