Not a U.S. Citizen but Earning in the U.S.? Here’s Your Simple Guide to Form 1040-NR
Why This Form Matters
If you’re doing any kind of business, job, or earning income from the United States—but you’re not a U.S. citizen—then taxes can feel confusing. Many people don’t even realize they still have to report their U.S. income.
This is where Form 1040-NR comes in. The Internal Revenue Service (IRS) uses this form for people who are non-residents for tax purposes but still earn money from U.S. sources.
Simply put: if you’re not a U.S. resident but making U.S. income, this form is for you.
What is Form 1040-NR in Simple Words?
Form 1040-NR is a tax return meant for nonresident aliens. It is used to report:
• Income earned from sources within the U.S.
• Taxes you owe (if any)
• Deductions and exemptions you are eligible to receive
Although it is not a long document, it does contain several important sections and schedules that you should be familiar with.
Key Parts of the Form You Should Know
Although the actual form is not very long, it does come with several schedules depending on your situation.
Main schedules include:
• Schedule A
This is for deductions such as state taxes and donations to U.S. charities.
- Schedule NEC (Not Effectively Connected Income)
This is for income not related to any business in the U.S., including:
o Dividends
o Interest
o Royalties - Schedule OI (Other Information)
This is where you report:
o Your residence
o Your travel history to the U.S.
o Tax treaty benefits
Who is Considered a Nonresident for Tax?
Understanding your status is very important. The IRS considers you a nonresident alien if:
• You are not a U.S. citizen, AND
• You don’t qualify as a tax resident
You are usually treated as a non-resident if:
• You don’t have a Green Card
• You fail the Substantial Presence Test
What Is the Substantial Presence Test?
This test will determine if you are considered a tax resident based on the number of days you stayed in the US.
You may be considered a tax resident if:
• You stayed in the US for 31 days in the current year, AND
• You stayed in the US for 183 days during the past 3 years using the following formula:
- Number of days in current year
- 1/3 of days in last year
- 1/6 of days in year before last
Important Exceptions You Should Know
You do not automatically become a tax resident even if you stayed in the US.
Some days are not counted towards the 183 days:
• You were prevented from leaving the US because of a medical condition
• You were a crew member
• Transit days (less than 24 hours)
• Commuting daily to and from Canada or Mexico
• Student visa
• Teacher visa
• Other visa types
Special Rule: Closer Connection Exception
Even if you pass the above requirements, you still may not be considered a tax resident if you have a closer connection to another country.
You may be considered a non-resident tax payer if:
• You stayed in the US for less than 183 days this year
• You have a tax home in another country
• You have a closer connection to another country
• You are not applying for a Green Card
2026 Updates You Should Know
Some important updates and trends in 2026:
• The IRS is using more data tracking systems to identify non-filers
• Tax treaty claims are reviewed more strictly
• Filing accuracy is more important than ever
• Digital compliance checks are increasing
Bottom line: small mistakes can now be caught more easily.
Filing Deadlines (Updated for 2026)
For most nonresident taxpayers:
• Standard deadline: April 15, 2026
• With extension (Form 4868): October 15, 2026
Missing deadlines can lead to penalties, so it’s important to file on time.
What Happens If You Don’t File?
Not filing Form 1040-NR can create serious problems.
Possible consequences:
• Late filing penalty (starting from 5% per month)
• Interest on unpaid taxes
• Risk of future compliance issues
• Difficulty with visas or financial matters
Ignoring it only makes things worse.
How Much Time Does It Take?
Filing this form is not always quick. This will take an average of 10-15 hours, depending on your financial situation and documents.
