How to read this page
South Carolina vs Rhode Island RSU tax in 2026
This page compares state supplemental withholding for South Carolina (SC) and Rhode Island (RI) 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).
South Carolina is higher by about $5 in state tax alone; net take-home favors Rhode Island by about $5.
No published flat supplemental rate (aggregate / table method). Educational estimate ≈6% — confirm with payroll tables.
Published state supplemental withholding at 5.99% on RSUs and other supplemental wages.
How each state’s rate works
South Carolina (Aggregate / table (estimate)): about 6% → $3,000 on the vignette.
Rhode Island (Published flat supplemental): about 5.99% → $2,995 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.
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.
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.
