Utah: flat PIT used as supplemental estimate
Utah has a flat personal income tax and no separate supplemental percentage in our source set.
When an RSU vest is paid separately, many payroll systems withhold near the flat PIT of 4.45%. That is the educational estimate shown here.
County or local add-ons (where any) are not included.
How Utah payroll usually handles RSU vests
When the RSU vest is paid separately, many employers apply ~4.45% PIT state rules plus federal 22% and FICA.
If the RSU vest is combined with regular wages, withholding may follow the aggregate method instead of these flat percentages (IRS Pub. 15 §7).
Employees should reconcile annual liability on Form 1040 — paycheck withholding is only an estimate.
How withholding scales with RSU size
At a constant rate, state tax scales roughly linearly: double the RSU vest and state withholding roughly doubles (before exemptions or method changes).
Above $1M supplemental wages in a year with one employer, federal withholding jumps to 37% on the excess (Pub. 15).
What this profile does not include
Local city or municipal wage taxes (for example NYC resident tax, Philadelphia wage tax, Ohio city income tax) are not in these figures.
California SDI, state disability, paid family leave premiums, and local school taxes are outside the supplemental income-tax line.
Confirm current employer guides linked in the sources section before relying on a stub estimate.

Utah RSU tax FAQs
Utah uses about 4.45% for flat supplemental withholding in our model (~$2,225 on $50,000 RSU vest (100 shares × $500 FMV) with $150,000 other annual income (flat supplemental method)).
On the vignette ($50,000 vest, $150,000 other income): about $16,089 total withheld ($11,000 federal + $2,864 FICA + $2,225 state), leaving ~$33,911 after-tax share value (~67.82 net shares after sell-to-cover).
Supplemental flat rates are a payroll shortcut when RSU income is withheld separately. Employers may instead use the aggregate method (combine with regular wages). Confirm with payroll and your state withholding tables.
Usually no under the flat supplemental method — both are supplemental wages. Timing and whether pay is combined with regular wages can change the stub via the aggregate method.
State income tax withheld may be itemized on Schedule A subject to the federal SALT cap. Whether you benefit depends on your full return.
About $11,000 (22% flat), the same as in every other state on this vignette — plus about $2,864 FICA.
