Differences in Tax Filing between F-1 OPT and H-1B
There are key differences in tax filing between F-1 OPT (a nonresident alien status) and H-1B (typically a resident alien status after meeting the Substantial Presence Test). Here’s a breakdown:
1. Tax Residency Status
- F-1 OPT (Nonresident Alien - NRA)
- Generally treated as a nonresident for tax purposes for the first 5 calendar years (exempt from the Substantial Presence Test under the “exempt individual” rule).
- After 5 years, may become a resident alien for tax purposes if meeting the Substantial Presence Test.
- H-1B (Resident Alien - RA)
- Usually becomes a resident alien for tax purposes once they meet the Substantial Presence Test (physically present in the U.S. for at least 183 days over 3 years, with a weighted calculation).
- Resident aliens are taxed on worldwide income (like U.S. citizens).
2. Tax Forms Used
- F-1 OPT (Nonresident Alien)
- Files Form 1040-NR (or 1040-NR-EZ if eligible) for federal taxes.
- May need to file Form 8843 (even if no income) to claim exempt status under the Substantial Presence Test.
- Wages reported on Form W-2 (Box 1 and Box 16 for state wages).
- H-1B (Resident Alien)
- Files Form 1040 (same as U.S. citizens).
- No need for Form 8843.
- Wages reported on Form W-2 (Box 1, 2, and state wages in Box 16).
3. Tax Treaties & Deductions
- F-1 OPT (NRA)
- May benefit from tax treaties (e.g., India-U.S. treaty allows exemption for scholarship income).
- No standard deduction (but may itemize deductions).
- Social Security & Medicare (FICA) Taxes:
- Exempt for the first 5 years on F-1 status (but some employers mistakenly withhold—must request refund via Form 843).
- H-1B (RA)
- Can claim the standard deduction ($13,850 for 2023, $14,600 for 2024).
- No FICA tax exemption (must pay Social Security & Medicare taxes).
- Tax treaties may still apply but are less common for H-1B workers.
4. State Taxes
- Both F-1 OPT and H-1B filers must pay state income tax if their state has one (e.g., California, New York).
- Some states (like Texas, Florida) have no income tax.
5. Dual-Status Tax Year (Transition Year)
- If an F-1 student transitions to H-1B mid-year and meets the Substantial Presence Test, they may be a dual-status alien (part-year resident).
- File both 1040-NR (for NRA period) and 1040 (for RA period).
- Must prorate income and deductions.
Key Takeaways
| Factor | F-1 OPT (Nonresident) | H-1B (Resident) |
|---|---|---|
| Tax Form | 1040-NR | 1040 |
| FICA Taxes | Exempt (first 5 yrs) | Not exempt |
| Standard Deduction | No (may itemize) | Yes ($14,600 in 2024) |

| Worldwide Income | Only U.S. income | Worldwide income |
What Should You Do?
- F-1 OPT: Ensure your employer does not withhold FICA taxes (if within 5 years).
- H-1B: File as a resident, claim deductions, and report all global income.
- Dual-Status Year: Seek a tax professional to avoid errors.
