As the UK's tax collection agency, HM Revenue & Customs, is reported to be preparing to reach out to "hundreds" of customers of a bank located in Puerto Rico over possible tax irregularities, financial services industry observers have been pointing out that the bank in question is located in one of five U.S. territories that, like the United States itself, have not signed up to the OECD's Common Reporting Standard (CRS).

Lawyers acting on behalf of the U.S.-born FATCA complainant known as "Jenny", who had been considering whether to go ahead with a challenge to the UK’s Information Commissioner’s Office's May 29 decision not to uphold her crowd-funded complaint over the way her personal data has been sent to the U.S. by British entities in recent years, have formally requested that HM Revenue & Customs agree to waive any so-called "adverse party costs", in the event that Jenny were to go ahead with her challenge – and lose.

The historical origins of privacy law, in the context of EU human rights principles, and the disproportionate elements of America's FATCA legislation are among the topics discussed in the first-ever podcast interview of the U.S.-born FATCA challenger known only as "Jenny", along with her lawyer, Mishcon de Reya partner Filippo Noseda.

The U.S. born, UK-resident woman whose crowd-funded complaint over data protection violations she alleged had resulted from the way HMRC had forwarded her personal information to the U.S. was recently not upheld by the UK's Information Commissioner's Office (ICO), is actively considering lodging a judicial review – but says that her legal advisers have told her she'll need to secure "£75,000 within the next 10 days" if she is to do so.

Americans who are tax-resident in the UK, and who have recently received Economic Impact Payments from the U.S. government (or who receive them in the weeks and months ahead), will not have to pay tax to HMRC, London-based U.S. tax expert David Treitel says.

The UK's Information Commissioner's Office has given HM Revenue & Customs 20 days to respond to queries having to do with a crowd-funded legal case against FATCA being brought by an American expat known publicly as “Jenny”.
