How to read this page

Arkansas vs Mississippi RSU tax in 2026

This page compares state supplemental withholding for Arkansas (AR) and Mississippi (MS) 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).

Mississippi is higher by about $150 in state tax alone; net take-home favors Arkansas by about $150.

Published state supplemental withholding at 3.7% on RSUs and other supplemental wages.

No published flat supplemental rate (aggregate / table method). Educational estimate ≈4% — confirm with payroll tables.

How each state’s rate works

Arkansas (Published flat supplemental): about 3.7% → $1,850 on the vignette.

Mississippi (Aggregate / table (estimate)): about 4% → $2,000 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.

What the state gap means

Flat supplemental rates differ by state; federal 22% and FICA rules are the same. Withholding is not your final tax bill when you file.

Limits of this comparison

NYC/local taxes, aggregate-method withholding, and equity vest timing are not modeled. Use the RSU calculator for custom vest amounts and other income.
