FACT Sheet: Foreign Account Tax Compliance Act (FATCA)
Every year, your employer, bank, the Social Security Administration, and anyone holding or investing your savings, sends you and the Internal Revenue Service (IRS) information about your accounts. This is a long-standing U.S. practice that combines patriotism and accountability and has created a culture of tax compliance.
However, for U.S. citizens living abroad and wealthy individuals with accounts in foreign banks, there was little accountability. While most Americans with foreign bank accounts paid the taxes they owed, some did not. For those, FATCA was passed.
