How to read this page
Idaho vs New York RSU tax in 2026
This page compares state supplemental withholding for Idaho (ID) and New York (NY) on $50,000 RSU vest (100 shares × $500 FMV) with $150,000 other annual income (flat supplemental method), calculated from our engine (same engine as the RSU vest calculator).
New York is higher by about $3,200 in state tax alone; net take-home favors Idaho by about $3,200.
Published state supplemental withholding at 5.3% on RSUs and other supplemental wages.
New York State published supplemental rate 11.7% (NYS-50-T-NYS, Jan 2026). NYC resident local tax is separate and not included.

Idaho (Published flat supplemental): about 5.3% → $2,650 on the vignette.
New York (Published flat supplemental): about 11.7% → $5,850 on the vignette.
Official state agencies for this pair only are linked in the sources section — not every state in the hub.
Federal and FICA are the same on this vignette
Both states withhold $11,000 federal income tax under the Pub. 15 flat method (22% on $50,000).
FICA is $2,864 in each (Social Security + Medicare on this YTD/RSU pair). The take-home gap is almost entirely state supplemental withholding.
Above $1M supplemental wages with one employer, federal withholding uses 37% on the excess — still the same rule in both states.
Same RSU vests, different state tax
The ladder recomputes engine results at $15k–$250k RSU vests with $150,000 other annual income.
When both sides use flat (or flat-PIT proxy) rates, the dollar gap scales roughly with RSU size.
Signing-RSU negotiations should still include regular wage tax and cost of living — not supplemental withholding alone.
What this comparison excludes
Local city taxes (NYC, Philly wage tax, Ohio municipalities) are not included.
Aggregate-method stubs can differ from the flat-percentage estimates shown here.
Final Form 1040 liability depends on annual brackets, deductions, and credits — withholding is a prepayment.
