Show the math
Federal (Form 1040-NR)
Wages $40,000 − pre-tax payroll $0 = $40,000 (W-2 box 1)
= adjusted gross income $40,000 − deduction $1,255 = taxable $38,745
- 10% on $12,400 ($0–$12,400) = $1,240
- 12% on $26,345 ($12,400–$50,400) = $3,161
FICA
Exempt (IRC 3121(b)(19)). On FICA wages of $40,000 it would be $3,060.
Oklahoma
Starting income $40,000 − standard deduction $6,350 − exemption $1,000 = taxable $32,650 → tax $1,255

Estimate for 2026 wages, single filer, a full year in one state. It is not tax advice and not your withholding: employers often withhold more from F-1 students, which you get back when you file. Scholarships, other income, catch-up contributions and most credits are not included.
No FICA for five years
F-1 and J-1 students skip the 7.65% Social Security and Medicare tax for their first five calendar years, including on CPT and OPT.
No standard deduction
Nonresident aliens are taxed on nearly every dollar federally. Indian students are the exception, and everyone can deduct the state tax they pay.
Treaties can cut your bill
33 countries' treaties exempt part of a student's wages, from $2,000 to $10,000 a year, and India's gives you the standard deduction. Pick your country above to apply yours.

Oklahoma questions students ask
Do F-1 students pay Oklahoma state income tax?
Yes, on wages earned in Oklahoma, at rates from 2.5% to 4.5%. The FICA exemption F-1 and J-1 students get covers only Social Security and Medicare, not state income tax. You can deduct the state tax you pay on your federal 1040-NR.
Can F-1 students take the Oklahoma standard deduction?
Yes. Oklahoma gives you its standard deduction ($6,350) even as a nonresident alien.
Does Oklahoma tax wages that a tax treaty exempts?
Generally no. Oklahoma starts from your federal income, which already leaves treaty-exempt wages out.
