Expats may decide to leave the U.S. due to work, retirement, or other reasons. Tax reduction may also be a motivation for moving to a foreign country, but the United States uses citizenship-based taxation. Therefore, the taxpayer still has a continuing obligation to file and pay U.S. taxes (although they may be eligible for some exclusions, such as the Foreign Earned Income Exclusion).
Tax Mistakes Expats Should Avoid
First, expats need to continue to file and pay their taxes. Many other countries use territorial-based taxation, which only taxes income earned inside the country. The United States, on the other hand, taxes citizens on all worldwide income.
