Frequently asked questions
Specific to this visa, state, and salary. Sourced to IRS, SSA, and state DOR.
How much does a F-1 OPT (after nra period (resident)) earn after tax on $350,000 in Connecticut?
A F-1 OPT holder (after nra period (resident)) grossing $350,000 in Connecticut takes home approximately $227,252 per year, or about $18,938/month. Total federal + state + payroll tax burden: $122,748 (35.07% effective rate).
Are F-1 OPT holders subject to FICA in this scenario?
Yes. Social Security 6.2% up to $184,500 (2026 wage base), Medicare 1.45% on all wages, plus 0.9% additional Medicare above the filing-status threshold.
Can the standard deduction be claimed in this scenario?
Yes — $16,100 federal standard deduction is applied (resident alien for tax purposes).
What state taxes apply in Connecticut?
Connecticut levies a flat 5.50% state income tax. On $350,000 that comes to $19,250.
How much would I save by moving to a no-state-tax state at this salary?
On $350,000, the same scenario in Texas (no state income tax) would net approximately $258,731 — about $31,479/year more than Connecticut. Florida, Washington, Nevada, South Dakota, Wyoming, Alaska, Tennessee, and New Hampshire give the same result. Cost-of-living adjustments not included.
How much would maxing out a 401(k) save me at this income?
Contributing the 2026 IRS limit of $23,500 pre-tax to a 401(k) would reduce federal income tax by roughly $8,225 at your 35.00% marginal federal bracket, plus $1,293 in state tax. (Note: 401(k) contributions still count as FICA wages, so Social Security and Medicare are unchanged.)
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. Connecticut 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.
What changes when an F-1 OPT student passes 5 calendar years in the US?
Three things flip simultaneously: (1) the FICA exemption ends — Social Security (6.2%) and Medicare (1.45%) now apply; (2) the standard deduction becomes available (~$16,100 single 2026); (3) you can elect MFJ if married. The net effect is usually a higher tax bill — FICA is ~7.65% of gross, while the standard-deduction savings is only ~22.00% × $16,100 ≈ $3,542.
