What's the complexity when switching F1 to H1B?
F1 students (and J1 teachers) are "exempt individuals" — first 5 calendar years on F1 don't count toward SPT. The day you transition to H1B, exempt status ends and SPT counting begins. This creates a dual-status year.
When does my US tax residency start?
Scenario A: Exhausted 5 F1 calendar years before transition year. Day-counting under SPT begins from day 1. Likely meet SPT, US resident for entire year.
Scenario B: Still in 5-year F1 exempt period and switch to H1B mid-year. F1 days don't count; H1B days do. SPT computed only on H1B days.
Scenario C: Converted F1 to H1B in October but on F1 5+ prior years. May meet SPT from H1B days plus weighted prior years.
Am I dual-status or full-year resident?
If you meet SPT counting H1B days:
- Non-resident Jan 1 to day before H1B start
- Resident H1B start to Dec 31
= Dual-status return.
If you don't meet SPT, full-year non-resident on Form 1040-NR.
Can I elect full-year resident?
Yes — via First-Year Choice OR if married to US resident, §6013(g). Avoids dual-status complexity.
For most F1-to-H1B transitions, dual-status doesn't save much (no standard deduction in dual-status). Electing full-year resident usually better.
FICA / Social Security implications
F1 students EXEMPT from FICA and Medicare. On H1B, FICA / Medicare apply.
Ensure employer correctly stopped FICA exemption when you switched. Often missed — either over-withhold FICA during OPT (refund via Form 843) or fail to start on H1B (you may owe employee portion).
What about Indian salary before US arrival?
If arrived from India for F1 and never had US presence before, pre-arrival Indian salary not US-taxable in F1 years. The first year you trigger US residency, pre-residency Indian income untaxed if dual-status. If full-year resident election, it enters US tax base — but FTC usually zeroes out US tax.
Spouse and family planning
If spouse is in India on H4 or hasn't entered US:
- Spouse needs ITIN to be claimed as dependent or file MFJ
- H4 spouse can sometimes work (H4 EAD) and get SSN
- Indian children on H4 need ITINs if claimed
We process ITIN W-7 applications — $200 per ITIN.
FBAR if I had Indian accounts before moving?
Yes. Year you become US resident, FBAR applies if foreign accounts exceeded $10,000 at any time — including months still on F1.
Common F1-to-H1B mistakes
- Filing full-year non-resident when SPT was met
- Missing FBAR for Indian accounts
- Filing MFJ in dual-status year without election
- Not stopping FICA exemption on H1B conversion
