Why Act Now?

It is important to understand your US tax obligations. The Internal Revenue Service now has a number of ways to find Americans living outside the US who are not reporting income or foreign bank accounts as well as Americans living in the US who invest internationally.

Did you receive a bank letter? Your banks and other financial institutions are now required, through FATCA legislation, to report the personal details of American clients to the IRS tax or local authority.


The IRS developed a system to actively locate non-compliant Americans wherever they are in the world.


If you are not compliant, your US passport can be revoked or you can be denied renewal.


Rewards are still being offered to anyone who turns in a non-compliant US person to the authorities.
