The Paris-based Association of Accidental Americans (Association des Américains Accidentels) is calling on its members and other accidental Americans – as well as other U.S. expats frustrated by the United States' citizenship-based tax regime – to join its campaign in support of efforts (by others) who are understood to be planning to launch a legal challenge against CBT, within the next few months.

A little over one month into the new year, a global challenge to the United States' citizenship-based tax regime is emerging on several fronts, as awareness continues to grow of the tax regime's major role in the many problems U.S. expats and so-called accidental Americans continue to struggle with.

If you were thinking of planning a protest by expatriate Americans against the U.S. system of citizenship-based taxation, it's difficult to think of a better day to do it than the date when expatriate American expats are obliged to file their U.S. tax returns by – which is to say, June 15 (two months after U.S. taxpayers' taxes are due). 

A group of American expats located in at least four different countries is laying the groundwork for a major legal challenge against "the application of U.S. citizenship-based taxation" to Americans who are living outside of the U.S.

As growing numbers of expatriate Americans are calling on U.S. lawmakers to replace America's problematic citizenship-based tax regime with a system that's based on a taxpayer's current country of residence, the Washington, DC-based American Citizens Abroad is urging expats, members of Congress and others to revisit its most-recent research report – which ACA officials say has some of the best data anywhere on the subject. 

Don Beyer, a U.S. Democratic congressman who represents a Virginia constituency, has introduced legislation he says is aimed at making life significantly easier for American expatriates, by making it easier for them to comply with their U.S. tax obligations. 

Convincing Congress and the Biden Administration of the need for the U.S. to move to a "residence-based" system of taxation is the No. 1 focus of American expatriate advocacy groups around the world right now.

It's only when Americans move overseas that they tend to discover something that few Homeland Americans are aware of: that the U.S. is the only country in the world that taxes on the basis of citizenship rather than residency – apart from Eritrea.

The American Citizens Abroad Global Foundation – the sister educational and research organization to the Washington, D.C.-based American Citizens Abroad advocacy group – today is unveiling a campaign to raise US$75,000 to fund a research project that it plans to help provide the ACA and others with fresh data that the ACAGF says will help to support arguments in favor of moving the U.S. to a Residence-Based Taxation system.

The U.S. Senate's Finance Committee today will hear from a number of experts on how the country's "international tax policy" is impacting U.S. workers, jobs and investment, during a "virtual hearing" scheduled to begin today at 9:30am Washington time (1:30pm GMT).
