How to read this page
New Mexico vs South Carolina bonus tax in 2026

New Mexico (Published flat supplemental): about 5.9% → $590 on the vignette.
South Carolina (Aggregate / table (estimate)): about 6% → $600 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 $2,200 federal income tax under the Pub. 15 flat method (22% on $10,000).
FICA is $765 in each (Social Security + Medicare on this YTD/bonus 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 bonuses, different state tax
The ladder recomputes engine results at $5k–$50k bonuses with $80,000 YTD wages.
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-bonus 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.
