Tax savings aside, keep in mind that citizenship renunciants are not only prohibited from possessing firearms, but also are prohibited from hiring armed bodyguards.
Why? It all goes back to the Civil War, and to a tax meant to deter potential draft dodgers from leaving the U.S. Today, the goal is to make sure that all of the income of U.S. citizens, whether they live and work in the U.S. or not, is reported to the Internal Revenue Service.The rules got trickier in 2010, when, in an effort to cut down on tax evasion, the Foreign Account Tax Compliance Act (fabulously, Fatca, for short) was passed into law. It basically said foreign institutions holding assets for U.S. citizens had to report the accounts or withhold a 30 percent tax on them if the information wasn’t provided. That led some foreign banks to shy away from opening accounts for expats.
