F-1, OPT, and CPT Tax Basics: Wages, Scholarships, and When Exempt-Individual Status Ends

Author: Chenchen Liu, CPA ｜ YCL Tax, Accounting & Advisory

Bottom line

If you study in the United States on F-1 and work under CPT (Curricular Practical Training) or OPT (Optional Practical Training), tax compliance turns on two tracks: (1) whether you are still an “exempt individual” for the Substantial Presence Test—students are generally limited to no more than five calendar years; and (2) how wages and scholarships are sourced and reported. Exempt-individual status affects whether days count toward SPT—it does not mean your income is tax-free. OPT/CPT wages are generally U.S.-source compensation. Scholarship sourcing follows separate rules. Triangle internationals at NCSU, Duke, UNC, and RTP often confuse visa status with tax residency around OPT. This article is compliance education, not visa or immigration advice, and it does not promise any tax result.

Background

IRS Publication 519 and the IRS Foreign Students and Scholars pages split temporary-student tax issues into two lines. First, tax residency: F/J/M/Q students who qualify as exempt individuals may exclude U.S. days from the Substantial Presence Test, generally for no more than five calendar years. After that framework, days usually count again; meeting the weighted 183-day test can make you a U.S. tax resident who files Form 1040. Claiming excluded days usually still requires Form 8843—even with no U.S. income (see this series’ Form 8843 article).

Second, income type and source. Wages paid for CPT/OPT services for a U.S. employer are generally U.S.-source compensation for a nonresident alien, often reported on Form W-2 and evaluated on Form 1040-NR. Scholarships and fellowships differ: amounts for qualified tuition and related expenses are treated differently from amounts for room and board, travel, or pay for required services; sourcing often looks to whether the payer is a U.S. person. U.S.–China treaty student provisions, Forms 8233 / W-8BEN, and Form 8833 disclosure are covered in this series’ treaty article—this piece does not market “treaty shortcuts.”

For Cary / RTP and Shanghai-connected families, friction usually looks like: treating the first OPT year as “still a student, so not a resident”; misclassifying CPT wages as “school scholarship”; or excluding SPT days after exempt years have ended. Compliance planning starts by aligning visa timeline, calendar-year exempt status, and wage/scholarship documents.

What changed / options compared

Note: The comparison below is common misconceptions vs compliance framing, not a legislative old-vs-new chart. Verify against current Pub. 519, Form 8843 / 1040-NR instructions, and IRS student pages.

1. Exempt individual vs tax-free

- Common misconception: F-1 / OPT “still a student” ⇒ U.S. wages need not be reported or taxed.

- Compliance framing: Exempt individual affects SPT day counts only. U.S.-source wages and taxable scholarship amounts may still be reportable. OPT/CPT does not automatically rewrite the student exempt-year formula—apply Pub. 519 to your calendar years and status history.

2. Student exempt-year limit

- Common misconception: A valid I-20 and continuing F-1 status forever exclude SPT days.

- Compliance framing: Student exempt-individual treatment generally applies for no more than five calendar years (limited exceptions such as re-establishing a foreign residence are in the current instructions). After that, days usually count toward SPT; a weighted total of 183 can mean tax residency.

3. CPT / OPT wages

- Common misconception: Internship pay is always a “school scholarship,” or “no green card means not U.S. income.”

- Compliance framing: Pay for personal services performed in the United States is generally U.S.-source. Nonresident filing often uses Form 1040-NR with Form W-2. Federal income-tax withholding and FICA treatment vary by status stage and statutory exceptions—confirm with the employer and IRS rules; this article does not decide your case.

4. Scholarships / fellowships

- Common misconception: Any document labeled “scholarship” is tax-free.

- Compliance framing: Qualified tuition-related amounts differ from living-expense or service-required amounts; sourcing and 1040-NR reporting follow payer and grant terms.

5. Form 8843

- Common misconception: Filing 1040-NR for OPT wages replaces 8843; or no income means no IRS forms.

- Compliance framing: Claiming exempt-individual day exclusions usually still requires Form 8843 (attached to 1040-NR or mailed separately to Austin). See series #4.

6. Handoff after exempt years

- Common misconception: F-1 visa stamp ⇒ always Form 1040-NR.

- Compliance framing: After exempt years end, apply SPT (and the green-card test if applicable). Meeting resident rules generally means Form 1040 and worldwide-income reporting. Switching from nonresident alien to resident is a compliance milestone—not an optional “more favorable form.”

7. Visa-advice boundary

- Common misconception: A CPA can decide whether you may apply for OPT / STEM OPT.

- Compliance framing: CPT/OPT eligibility and I-20 endorsement are immigration / DSO matters. YCL helps with tax residency, forms, and income classification only.

Self-check: are you affected?

1. F-1 at NCSU / Duke / UNC or an RTP employer, on or planning CPT / OPT / STEM OPT, with or expecting Form W-2 wages.

2. You are in calendar year 4–5 (or later) as a student and unsure whether exempt-individual day exclusion still applies.

3. You receive both school scholarships/fellowships and internship wages and need clean classification for 1040-NR.

4. F-2 spouse or children in the United States—each often needs their own Form 8843; your OPT wages do not cover their filings.

5. You assume FICA is “always exempt” or “always due” during OPT without checking your current status stage and employer withholding.

6. Exempt years are ending; next year you may become a tax resident and should build awareness of information reporting (FBAR / Form 8938, etc.—see existing YCL articles; not rehashed here).

7. Your school gave a generic tax-season link; you need a CPA-ready packet: day ledger + W-2 + 1042-S/scholarship letters.

Simplified example (illustrative only)

Scenarios below illustrate exempt-year and income-type logic only. They are not filing conclusions and do not compute tax.

1. Scenario A — Short master’s + CPT: Student Wang first entered on F-1 in August 2024; summer 2025 CPT produces a W-2. If 2024–2025 remain within the student exempt framework, U.S. days may be excluded from SPT, but Form 8843 is still typically required, and CPT wages are evaluated on a nonresident path (1040-NR). A separate 1042-S scholarship must be classified apart from wages.

2. Scenario B — Long Ph.D. + OPT: Student Li has claimed student exempt status for multiple calendar years. In a year after the usual student framework, days may count toward SPT; a weighted total ≥ 183 can mean tax residency even if the I-20 still shows F-1/OPT. The main return may shift from 1040-NR to Form 1040—verify with travel records and Pub. 519, not “still on OPT” alone.

3. Scenario C — Fellowship vs wages: An RTP-linked “fellowship” requires research services. The label may not control; amounts may be closer to compensation than to a qualified tuition scholarship—read the award terms against Pub. 519.

4. Scenario D — Dependents: The F-1 files 1040-NR (if required) with 8843; F-2 family members in the U.S. usually each need their own 8843—do not assume one form covers the household.

Figures are illustrative. Real entries, exempt limits, treaty positions, and withholding change outcomes. No filing result is promised.

Action plan and timeline

1. Now: Build a visa/I-20 timeline plus U.S. day ledger; gather W-2s, 1042-S forms, scholarship letters, and CPT/OPT approval copies.

2. Each December–January: Decide whether this calendar year still qualifies as student exempt individual; trial-run SPT if days must count; lean toward 1040-NR vs 1040 accordingly.

3. With OPT/CPT wages: Confirm name, ITIN or SSN, address, and withholding with the employer; keep pay stubs.

4. Filing season: Claiming exempt days → prepare Form 8843; if a return is due → file 1040-NR or 1040 per status. Due dates follow current instructions (many wage-withholding calendar-year filers face mid-April; some 1040-NR cases use June 15).

5. Year before exempt limits end: Schedule a compliance review for worldwide-income and information-reporting readiness (pointer to existing FBAR/8938/3520 pieces).

6. Status change (F-1→H-1B, etc.): Day-count and FICA rules often change together—see this series’ H-1B/L-1/O-1 article; immigration steps stay with counsel/DSO.

7. When unsure: Bring I-20, I-94, three-year travel calendar, and income documents to a YCL Free Consultation.

FAQ

Q: I am still F-1 on OPT. Do I always file Form 1040-NR?

A: Not always. The main return follows exempt-individual status, the Substantial Presence Test (and green-card test if applicable)—not the F-1 notation alone. After exempt years end, you may be a tax resident filing Form 1040 even while on OPT.

Q: Are CPT/OPT wages taxable? Does “exempt individual” make wages tax-free?

A: Exempt individual mainly affects SPT day counts—it does not make wages tax-free. U.S.-source compensation is generally still reportable under nonresident or resident rules. Withholding and any FICA exception depend on status stage and employer facts.

Q: I have only a scholarship and no wages. Do I still need Form 8843?

A: If you claim student exempt-individual day exclusions, Form 8843 is usually still required even without wages. Whether the scholarship is taxable is a separate question under grant terms and sourcing rules.
