Discussions are ongoing regarding the elimination of “double-taxation” on Americans living abroad, a move that has gained notable support, particularly from Republicans Overseas. The group emphasizes former President Donald Trump’s endorsement of ending this practice, which burdens expatriates. Current tax provisions, like the Foreign Tax Credit and Foreign Earned Income Exclusion, already aim to reduce the impact of double taxation, allowing U.S. citizens abroad to offset their U.S. tax obligations with taxes paid to foreign governments, but advocates argue that more reform is necessary to fully resolve the issue.
