Quick answer: If you’re a nonresident alien with any U.S. income (wages, scholarship, dividends, rental, etc.), you almost certainly need to file Form 1040-NR — and most people leave $4,000–$18,000 on the table by not doing it correctly.
Real Story #1: How Priya From Mumbai Got Back $18,400
She thought: “Tax is already paid. Nothing I can do.”
Wrong.
Under Article 21 of the U.S.–India tax treaty, Indian students can claim the full U.S. standard deduction and exclude up to $5,000–$10,000 of scholarship income.
Result? We filed her 1040-NR → $18,400 refund in 19 days.
What Is Form 1040-NR and Who Must File It?
Form 1040-NR is the tax return for nonresident aliens who have U.S.-source income or want to claim a refund.
You must file if you:
- Had any U.S. wages (even if taxed)
- Received a scholarship or fellowship grant
- Earned rental income from U.S. property
- Had dividends, interest, or royalties subject to withholding
- Want to claim tax treaty benefits or a refund
ECI vs FDAP: The One Distinction That Saves Thousands
| Income Type | Tax Rate | Deductions Allowed? | Real-World Impact |
|---|---|---|---|
| ECI (Effectively Connected Income) Wages, self-employment, U.S. business | 10%–37% graduated | YES – full deductions | Can reduce tax to $0 |
| FDAP (Fixed, Determinable, Annual, Periodical) Dividends, most scholarships, royalties | 30% flat (or 0%–15% with treaty) | Generally NO | Treaty is your only hope |
