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 $11,475 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.

Show the math

  1. Gross salary: $150,000 .
  2. Federal taxable income: $150,000 (after standard deduction of $0).
  3. Federal income tax: $28,598 — 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
  4. 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.
  5. State tax: $9,000 (income tax $9,000 + SDI/local $0).
  6. Total tax: $37,598 = 25.07% of gross.
  7. Take-home: $150,000 − $37,598 = $112,402.
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)

SC price level: 94.5 (US average = 100). Your $112,402 nominal take-home buys roughly $118,944 worth of goods and services at US-average prices — about $6,542more, because SC is 5.5% cheaper than the national average.

Frequently asked questions

Specific to this visa, state, and salary. Sourced to IRS, SSA, and state DOR.

How much does a F-1 OPT earn after tax on $150,000 in South Carolina?
A F-1 OPT holder grossing $150,000 in South Carolina takes home approximately $112,402 per year, or about $9,367/month. Total federal + state + payroll tax burden: $37,598 (25.07% effective rate).
Are F-1 OPT holders subject to FICA in this scenario?
No. F-1 OPT holders in NRA status are exempt from Social Security and Medicare for the first 5 calendar years (IRC §3121(b)(19), IRS Pub 519).
Can the standard deduction be claimed in this scenario?
No — as an NRA without an applicable tax treaty, the federal standard deduction is not available. NRAs may itemize state and local taxes paid only.
What state taxes apply in South Carolina?
South Carolina levies a flat 6.00% state income tax. On $150,000 that comes to $9,000.
How much would I save by moving to a no-state-tax state at this salary?
On $150,000, the same scenario in Texas (no state income tax) would net approximately $121,402 — about $9,000/year more than South Carolina. Florida, Washington, Nevada, South Dakota, Wyoming, Alaska, Tennessee, and New Hampshire give the same result. Cost-of-living adjustments not included.
How are bonuses and RSU vesting taxed for F-1 OPT holders?
Bonuses and RSUs are supplemental wages. Federal supplemental withholding is a flat 22% on amounts up to $1M, then 37% above. South Carolina applies its standard income-tax rules. FICA still applies if the visa is not FICA-exempt. This is withholding, not the final tax — high earners often underwithhold and owe at filing time.
