The Federal Register has just published the names of 360 former Americans who renounced citizenship in the fourth quarter of 2011. This brings the total number of published renunciants for last year to 1,781, compared to 1,485 for 2010. This includes 499 from January to March, 519 from April to June, 403 from July to September, and 360 from October to December. Internal Revenue Code Section 6039G requires that “[n]otwithstanding any other provision of law, not later than 30 days after the close of each calendar quarter, the Secretary shall publish in the Federal Register the name of each individual losing United States citizenship (within the meaning of section 877 (a) or 877A) with respect to whom the Secretary receives information under the preceding sentence during such quarter.” It’s an open question whether this list is actually complete. The RenunciationGuide.com website has expressed concerns about the completeness and quality of the data. International tax lawyer Andrew Mitchel at one point concluded that this list should only contain “covered expatriates”, but later re-examined the issue and concluded that it contains the names of all former Americans who lost citizenship in the period in question.
Update: Andrew Mitchel also just put up some nice charts on his blog with the number of published renunciants by year and by quarter, going back to 2004.
