In general, U.S. persons and permanent residents (a.k.a “green-card” holders), even those living outside the United States, must report their worldwide income, and therefore are required to file certain U.S. tax and other informational returns unless exempt under very limited circumstances. Non-U.S. persons (a.k.a “non-resident aliens” or “NRAs”) may also be subject to U.S. taxation based on certain U.S. source income, investments, or business activities.

The ATAS team will provide you with the highest quality of professional advice and U.S. tax preparation, in order to complete and timely file your individual income tax returns and other tax related documents.
