How to read this page
North Dakota vs Arizona RSU tax in 2026
This page compares state supplemental withholding for North Dakota (ND) and Arizona (AZ) 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).
Arizona is higher by about $500 in state tax alone; net take-home favors North Dakota by about $500.
Published state supplemental withholding at 1.5% on RSUs and other supplemental wages.
No separate supplemental table; educational estimate uses the state’s flat PIT ≈2.5%.
How each state’s rate works
North Dakota (Published flat supplemental): about 1.5% → $750 on the vignette.
Arizona (Flat PIT proxy (no separate table)): about 2.5% → $1,250 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.
