F-1 OPT · North Dakota · Tax year 2026
F-1 OPT take-home pay in North Dakota, salary
That's $7,967/month or $3,677/biweekly, after federal income tax and state income tax (20.33% 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 $9,180 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.
