American Citizens Abroad

Welcome to the newly redesigned American Citizens Abroad (ACA) website!  If you are a current ACA member who has not reactivated your account on our new website then see Help page for information. 

ACA is a Washington, DC- based qualified 501(c)(4) non-profit, non-partisan, advocacy organization that represents the legislative and regulatory concerns of five million US citizens living and working overseas to the US Government. ACA does not provide or recommend tax, legal or investment advice. For resources, visit the ACA Expat Tax Services Directory.

ACA advocates on many issues but this year we are laser focused on tax reformCongress will pass tax legislation in 2025 and Residence based taxation (RBT) must be part of that package. There is a Presidential promise to end double taxation and RBT legislation has been introduced in Congress. See our fundraiser to learn why you need ACA in the fight for tax reform for U.S. citizens overseas.  Visit our Taxation page to learn more about our past and present efforts.
