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.

The ladder recomputes engine results at $15k–$250k RSU vests with $150,000 other annual income.
If either state uses Vermont’s 30%-of-federal rule, Wisconsin bands, or an aggregate proxy, the gap may not scale as a simple constant percentage — check each ladder row.
Signing-RSU negotiations should still include regular wage tax and cost of living — not supplemental withholding alone.
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.

Vignette net: $33,136 (SC) vs $33,261 (VA).
Flat supplemental rates differ by state; federal 22% and FICA rules are the same. Withholding is not your final tax bill when you file.
NYC/local taxes, aggregate-method withholding, and equity vest timing are not modeled. Use the RSU calculator for custom vest amounts and other income.
