F-1 OPT · California · Tax year 2026
F-1 OPT take-home pay in California, salary
That's $5,274/month or $2,434/biweekly, after federal income tax and state income tax (20.89% effective tax rate).
Why this number differs from a generic paycheck calculator
F-1 OPT holders are FICA-exempt — generic calculators add ~7.65% you don't owe.
As a nonresident-alien F-1 OPT holder, you don't owe Social Security (6.2%) or Medicare (1.45%) on wages earned for services your visa authorizes. Generic paycheck calculators assume W-2 employee status and quietly add this 7.65% on top — making their take-home roughly $6,120 lower than the correct number. IRC §3121(b)(19) / IRS Pub 519.
NRAs cannot claim the federal standard deduction.
Generic calculators silently apply the $16,100 single standard deduction. As a nonresident alien (no applicable treaty), you don't get it — that's roughly $3,542–$3,864 more federal tax at typical bracket rates. IRS Pub 519.
California SDI is 1.30% of all wages, with no wage-base cap (since 2024).
Many calculators still apply the pre-2024 $153,164 wage base. We apply 1.30% to the full $80,000 per the SB 951 reform — that's $1,040 on this scenario, vs. $1,040 under the old cap. CA EDD — SDI rate notice.

Show the math
- Gross salary: $80,000 .
- Federal taxable income: $80,000 (after standard deduction of $0).
- Federal income tax: $12,312 —
computed by stepping through the SINGLE progressive brackets:
- 10% on income up to $12,400
- 12% on income up to $50,400
- 22% on income up to $105,700
- 24% on income up to $201,775
- 32% on income up to $256,225
- 35% on income up to $640,600
- 37% on income above the previous cap
- FICA exemption: $0 — this visa is exempt from Social Security and Medicare as a nonresident alien (NRA) under IRC §3121(b)(19) / IRS Pub 519.
- State tax: $4,403 (income tax $3,363 + SDI/local $1,040).
- Total tax: $16,715 = 20.89% of gross.
- Take-home: $80,000 − $16,715 = $63,285.
Assumptions used in this calculation (2)
- NRAs cannot claim the standard deduction (exception: F-1/J-1 students from India under treaty Article 21).
- F-1 OPT holders are FICA-exempt for the first 5 calendar years (Social Security + Medicare = $0 while NRA).
Real purchasing power (cost-of-living adjusted)
CA price level: 113.2 (US average = 100). Your $63,285 nominal take-home buys roughly $55,905 worth of goods and services at US-average prices — about $7,379less, because CA is 13.2% more expensive than the national average.
