California vs. Washington: which has lower taxes for a F-1 OPT earning $350,000?
For a single-filer F-1 OPT grossing $350,000, Washington nets approximately $33,023 more per year (9.44% of gross) than California. Washington take-home: $258,731. California take-home: $225,707.
What's driving the difference between California and Washington?
California uses progressive state brackets. Washington has no state income tax. Federal income tax and FICA are identical in both states (they're federal). The state delta is the difference.
Does cost of living change the answer?
Yes — significantly. This page only computes after-tax income. Housing, transit, taxes on goods (sales tax), and state-specific costs (e.g. auto registration) often dwarf the income-tax difference. As a rough rule: high-tax states tend to have higher cost of living too, so the take-home advantage of a no-tax state often understates the real-purchasing-power advantage.
What about the first year on a F-1 OPT?
F-1 OPT holders are FICA-exempt as nonresident aliens (typically the first 5 calendar years for F-1, 2 for J-1). FICA is $0 in both states. Standard deduction is generally unavailable to NRAs except F-1/J-1 students from India.
