What is Form 1040-NR?
Form 1040-NR (U.S. Nonresident Alien Income Tax Return) Form 1040-NR is used by nonresident aliens to report US-source income and calculate their US tax liability. It's the nonresident equivalent of Form 1040. Nonresidents are taxed only on US-source income, not worldwide income.

Who Needs to File Form 1040-NR?
Nonresident aliens with US-source income including wages, business income, investment income, or other fixed/determinable income connected with a US trade or business.
Non-Resident Relevance
If you are a non-resident entrepreneur with a US LLC or US-source income, Form 1040-NR may be a critical part of your US tax compliance. Consult with a qualified tax professional to determine if this form applies to your situation.
Filing Deadline
April 15 if you had wages subject to withholding; June 15 if you had no wages subject to withholding. 6-month extension available.
Filing on time is critical. If you need more time, file Form 7004 for an automatic 6-month extension before the original due date. Note that an extension of time to file is not an extension of time to pay.
Penalties for Non-Compliance
Penalty Warning
5% of unpaid tax per month (up to 25%) for late filing. 0.5% per month (up to 25%) for late payment. Interest accrues from the due date.
The IRS enforces these penalties strictly, especially for information returns related to foreign-owned entities. In many cases, there is no reasonable cause exception, making timely filing essential.
How to Complete Form 1040-NR
Here is a section-by-section breakdown of Form 1040-NR:
Filing Status and Exemptions
Nonresidents have limited filing status options — typically "Single nonresident alien" or "Married nonresident alien."
Effectively Connected Income (ECI)
Income effectively connected with a US trade or business, taxed at graduated rates (10%–37%).
FDAP Income (Schedule NEC)
Fixed, Determinable, Annual, Periodical income not connected with US business — taxed at a flat 30% (or reduced treaty rate).

Only deductions connected with ECI are allowed. Standard deduction is generally not available to nonresidents (exceptions for Indian and South Korean students).
Tax Credits
Limited credits available including foreign tax credit and certain education credits.
Payments and Refunds
Withholding from Forms W-2, 1042-S, and estimated tax payments.
Filing Tip
Given the complexity and steep penalties associated with Form 1040-NR, we strongly recommend working with a qualified tax professional who has experience with non-resident tax filings. Errors or omissions can trigger significant penalties.
Common Mistakes to Avoid
These are the most frequent errors we see when clients attempt to file Form 1040-NR on their own:
- Filing Form 1040 instead of 1040-NR as a nonresident alien
- Claiming the standard deduction (not available to most nonresidents)
- Not attaching Schedule NEC for FDAP income
- Not reporting income that had withholding (1042-S income)
- Failing to claim treaty benefits that could reduce tax
- Not filing because all income was withheld upon — you may be due a refund
