How to Know If You Are a Non-U.S. Resident for Tax Purposes and Why It Matters
Many people earning U.S. income are unsure whether they are considered U.S. residents or non-U.S. residents for tax purposes. This distinction is important because it affects which forms you file and whether you need an ITIN.
At Nolly.com, we help clients worldwide understand their tax status and file correctly.
Residency for Tax Is Not About Citizenship
Tax residency is different from citizenship.
You can be a citizen of another country and still be considered a U.S. resident for tax purposes, or a non-U.S. resident.
The IRS uses specific tests to determine this.
The Green Card Test
If you hold a valid U.S. green card at any time during the year, you are considered a U.S. resident for tax purposes.
If you do not have a green card, this test does not apply.
The Substantial Presence Test
The substantial presence test looks at how many days you were physically present in the United States over a three-year period.
If you meet the required number of days, you may be considered a U.S. resident for tax purposes, even without a green card.
Many short-term visitors do not meet this test.
When You Are a Non-U.S. Resident
You are usually considered a non-U.S. resident if:
You do not have a green card
You do not meet the substantial presence test
Most international investors, property owners, and casino visitors fall into this category.
Why Residency Status Matters
Your residency status determines:
Which tax return you file
Whether you file a 1040 or a 1040NR
Whether you need an ITIN
How your income is taxed
Filing the wrong return can cause IRS delays or penalties.
Non-U.S. Residents and ITINs
If you are a non-U.S. resident and must file a U.S. tax return, you usually need an ITIN.
This applies to rental income, investment income, FIRPTA property sales, and casino winnings.
Common Mistakes People Make
Assuming residency based on visa type

Ignoring U.S. income reporting
These mistakes often lead to missed refunds.
