Best Expat Tax Services for Americans Abroad: 2025 Comparison

Choosing an expat tax service is a big decision, especially when U.S. tax rules for Americans abroad are anything but simple. Between FBAR, FATCA, and the Foreign Earned Income Exclusion, it’s easy to make costly mistakes without expert help.
This guide compares what to look for in quality expat tax services, explains key differences between providers, and shows why thousands of expats trust Greenback with their U.S. taxes year after year.
Not every tax service can effectively handle expat situations due to complex requirements like international tax treaties and specialized forms. Here’s how to identify and compare your options.
