On F-1/OPT — do I file 1040 or 1040NR? My school and my accountant disagree.
"Exempt individual" doesn't mean exempt from tax — it means your days are excluded from the substantial presence test (SPT). Per IRS Publication 519:
The 5-year exempt rule
"Exempt individual" doesn't mean exempt from tax — it means your days are excluded from the substantial presence test (SPT). Per IRS Publication 519:
- F, J, M, and Q visa students are exempt for the first 5 calendar years of presence. Any part of a calendar year counts as a full year.
- The 5 years are a lifetime allowance — they don't reset if you leave and come back on a new F-1.
During those 5 years, the SPT effectively can't apply to you, so you're a nonresident alien regardless of how many days you were actually here. Your OPT wages are U.S.-source income and go on Form 1040-NR.
Once you've used up the 5 years, your days count normally. The SPT is met if you're present at least 31 days in the current year and 183 days on a weighted 3-year basis (all of this year's days + ⅓ of last year's + ⅙ of the year before). A typical F-1 student in year 6 who stayed all year easily passes — and files Form 1040.
| Situation | Residency | Form |
|---|---|---|
| F-1/OPT, within first 5 calendar years | Nonresident alien | 1040-NR (+ 8843) |
| F-1/OPT, 6th calendar year, meets SPT | Resident alien | 1040 |
| F-1/OPT, 6th calendar year, fails SPT (e.g., arrived late) | Nonresident alien | 1040-NR (+ 8843) |
Why the forms are fundamentally different
| Form 1040-NR | Form 1040 | |
|---|---|---|
| Income taxed | U.S.-source only | Worldwide |
| Filing status | Generally single or married filing separately | All statuses incl. joint |
| Standard deduction | Not allowed (rare treaty exceptions) | Allowed |
| Home-country income | Not reported | Must be reported (with foreign tax credit possible) |
Filing the wrong one has real consequences: a nonresident filing 1040 drags foreign income (e.g., wages from a job back home, foreign bank interest) into the U.S. return; a resident filing 1040-NR underreports and risks penalties.
Two breaks F-1 nonresidents often miss
- FICA exemption. Nonresident F-1 students working on campus, CPT, or OPT are exempt from Social Security and Medicare tax under IRC §3121(b)(19). If an employer withheld FICA by mistake, ask the employer for a refund first; if that fails, claim it from the IRS on Form 843.
- Treaty exemption. Under Article 20 of the U.S.–China tax treaty, a Chinese full-time student can exclude up to $5,000 per year of employment income. Claim it on the 1040-NR; you still must file even if the exemption wipes out all tax.
Also note: every F/J nonresident must file Form 8843 each year — even with zero U.S. income — simply to document the exempt-individual status.
Frequently asked questions
My accountant filed 1040 for me on OPT. Is it too late to fix?
No, but fix it. Filing 1040 as a nonresident is a common error (TurboTax defaults to the resident flow). File a corrected return: Form 1040-X with the correct Form 1040-NR attached. The wrong filing can also cause trouble later — residency misstatements can surface in future visa or green-card applications.
I switched to H-1B in October of my 6th year. Which form?
That's typically a dual-status year: nonresident while on F-1/OPT (exempt days), resident once the H-1B started and the SPT was met. File Form 1040 marked "Dual-Status Return" with a 1040-NR "Dual-Status Statement" attached. See our guide on dual-status years for the full mechanics.
Does filing 1040-NR hurt my future immigration applications?
The opposite — a clean, correct filing history helps. What's risky is years of no filing when you owed one, or resident filings that don't match your visa status.
