Marvell Technology vesting in Utah
Marvell Technology runs a quarterly RSU vesting schedule. For Utah residents, each vest is a taxable event: federal supplemental withholding at 22% up to $1M YTD and 37% above, plus 4.65% state withholding at the top Utah bracket, plus Medicare, plus Social Security up to the annual wage base.
The withholding gap
A senior Marvell Technology engineer earning $300k base plus $400k RSU in Utah sits at a combined marginal rate near 39.6%. Federal supplemental withholds only 22% on the RSU portion. The gap shows up at April filing unless you cover it with quarterly estimates or W-4 additional withholding.
Utah-specific planning moves
Utah taxes long-term capital gains as ordinary income, so holding past one year gives only federal savings (LTCG 15-20% versus ordinary 32-37%). State 4.65% applies either way.
Moving in or out
If you plan to move during an active $Marvell Technology vesting schedule, trailing-nexus rules apply. Utah will generally source the portion of each tranche earned while you were a resident, via workday allocation between grant and vest. Document your move date, work location per pay period, and any remote-work arrangements.
