Yes, Americans Pay Taxes No Matter Where They Live
The US citizenship-based taxation system and why it matters
The United States is one of only two countries in the world (alongside Eritrea) that taxes citizens on worldwide income, regardless of where they live or earn. If you're a U.S. citizen or Green Card holder, you have a filing obligation with the IRS every single year, even if you haven't set foot in America in a decade, owe zero tax, and are paying taxes to another country.
Here's the good news: the tax code provides powerful tools designed for Americans abroad. Used correctly, many expats and digital nomads can legally reduce their U.S. tax bill to zero, or close to it. The problem is these tools are complex, interact in non-obvious ways, and the penalties for errors are severe.
