Federal (Form 1040)
Wages $100,000 − pre-tax payroll $0 = $100,000 (W-2 box 1)
= adjusted gross income $100,000 − deduction $16,100 = taxable $83,900
- 10% on $12,400 ($0–$12,400) = $1,240
- 12% on $38,000 ($12,400–$50,400) = $4,560
- 22% on $33,500 ($50,400–$105,700) = $7,370

FICA from day one
The student exemption ends with F-1 status: 7.65% Social Security and Medicare comes out of H-1B pay from the first day, even in a nonresident year.
Taxed like a resident
A full year on H-1B makes you a resident alien: the same brackets as a citizen, the $16,100 standard deduction, $32,200 filing jointly.
The F-1 to H-1B year
An October 1 start leaves 92 days in H-1B status, so within your five student years you stay a nonresident for that year. OPT months stay FICA-free.

South Carolina H-1B tax questions
How much is South Carolina income tax on an H-1B salary?
About $5,286 on $120,000 for a single filer in 2026. South Carolina taxes an H-1B worker like any resident of the state: H-1B is not a special category for state tax.
What else comes out of an H-1B paycheck in South Carolina?
Federal income tax and 7.65% Social Security and Medicare.
Do I file a South Carolina return as an H-1B worker?
Yes, if your income is over South Carolina's filing threshold, which most full-time salaries are: as a resident of South Carolina if you live there, or as a nonresident if you only work there. In the year you move to the state you usually file as a part-year resident.
Can I file jointly with my H-4 spouse?
Yes, and it usually lowers the tax: the joint standard deduction is $32,200 and every bracket is twice as wide. On $120,000 in Texas with a spouse who has no income, federal income tax falls from $17,570 to $10,040. A spouse who is not a resident by days can still be on the return if you both choose to treat them as one (IRC 6013(g)); they need an SSN or an ITIN.
With a spouse abroad: Filing jointly with a nonresident spouse
What is my tax in the year I switch from F-1 to H-1B?
If the year is within your five student years and your H-1B starts on October 1, you have 92 days in H-1B status and are a nonresident for the whole year: Form 1040-NR, no standard deduction, and Social Security and Medicare only on the H-1B pay. A start on or before July 2 usually makes it a dual-status year. In your sixth calendar year you are a resident all year. Pick your H-1B start date above to work it out.
