Non Resident Tax Returns

Navigating the maze of U.S. tax laws can be a daunting experience, especially for non-U.S. citizens unfamiliar with the nuances and intricacies of the American tax system. The status of an individual, whether a resident alien or a non-resident alien, dramatically impacts how they're taxed. It's essential to have a clear understanding of this to ensure compliance and avoid potential pitfalls.


Defining Non-Resident Alien A non-resident alien, for the uninitiated, refers to someone who isn't a U.S. citizen or a Green Card holder. Such individuals must file a non-resident tax return and are typically only required to report U.S. source income. However, passing either the green card test or the substantial presence test can change this, making them liable to file taxes as a U.S. resident, thereby reporting their worldwide income.


Breaking Down the Tests


  • Green Card Test: If the U.S. Citizenship and Immigrant Service (USCIS) grants you an alien registration card (commonly known as the green card), you're considered a lawful permanent resident. With the green card, you've secured the privilege to reside permanently in the U.S. based on immigration laws. This status remains intact unless you voluntarily renounce or abandon your Green Card in writing to the USCIS.
  • Substantial Presence Test: This test revolves around your physical presence in the U.S. To pass:

You should be present for at least 183 days in the current year.

You should have a combined presence of at least 183 days over a 3-year period, which includes the current year and the two years immediately preceding it. Here, every day of the current year is counted, one-third of the days from the prior year, and one-sixth of the days from the year before that.


Passing the Substantial Presence Test classifies you as a resident alien for tax purposes, making your global income taxable in the U.S., akin to U.S. citizens.


Tax Filing Necessities Non-resident aliens should be vigilant about filing their non-resident tax return if they have any U.S. source income.


U.S. Tax Treaties and Their Role The U.S. has inked tax treaties with numerous foreign nations. These treaties play a crucial role for non-resident aliens as they might reduce or entirely waive U.S. tax on certain income types, like capital gains, dividends, interests, and pensions. To leverage these benefits, one needs to review each treaty carefully.
