A growing number of people claim that they will move outside the U.S. if Donald Trump becomes president. Others want out if Kamala Harris is elected. If you move but keep your citizenship, the U.S. will continue to tax you. The U.S. taxes its citizens on their worldwide income, no matter where they reside. Expatriates can alleviate some of the sting of double taxation through foreign tax credits and other breaks, such as the foreign earned income and housing exclusions. Trump says he supports ending the double taxation of Americans living overseas. We don’t know exactly what this means. A lobbying group representing U.S. expats has been pushing for years for a regime that taxes expatriates on U.S. income but not foreign income. They also want the U.S. to stop taxing U.S. income of expats who live in countries that tax their U.S. income. This group supports Trump’s pledge. U.S. expats won’t be able to escape the rules on reporting foreign accounts. Also, people who decide to give up their U.S. citizenship could owe an exit tax if their average annual tax for the five years before losing citizenship exceeds $201,000 or they have at least $2 million of net worth. They’ll be treated as selling all their assets for fair market value on the day before their loss of citizenship and will be taxed on the profit from the deemed sale that exceeds an exemption of $866,000.
