It depends. If you have US income, other than your international organization salary, you may need to file a US tax return. G-4s often must file to report rental property holdings in the United States (even if the properties have losses), US dividends, and worldwide capital gains, among other items.

We assist G-4s in all aspects of tax return filings. We advise you on what you must do by law, while helping you avoid mistakes. We also help you take advantage of little-known benefits and reduce your risk of an IRS audit.
