Who Must File?

All U.S. citizens and resident aliens must file a U.S. individual income tax return, even if they permanently live outside the United States and may not owe any tax because of income exclusion or tax credit.

What is the Foreign Account Tax Compliance Act (FATCA)

According to “Foreign Account Tax Compliance Act” (FATCA) all foreign financial institutions are required to identify their clients with U.S. tax liability, report to the competent U.S. authorities information about such clients and assets they hold.

Therefore, U.S. citizens who maintain a bank account in Greece may be asked to fill out form W-9 by their bank. Your social security number will be required.

If you do not have a Social Security Number please contact our Federal Benefits Unit for information on how to obtain one.
