Shopify vesting in New Jersey
Shopify runs a quarterly RSU vesting schedule. For New Jersey residents, each vest is a taxable event: federal supplemental withholding at 22% up to $1M YTD and 37% above, plus 10.75% state withholding at the top New Jersey bracket, plus Medicare, plus Social Security up to the annual wage base.
The withholding gap
A senior Shopify engineer earning $300k base plus $400k RSU in New Jersey sits at a combined marginal rate near 45.8%. 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.
New Jersey-specific planning moves
New Jersey 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 10.75% applies either way.
Moving in or out
If you plan to move during an active $Shopify vesting schedule, trailing-nexus rules apply. New Jersey 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.
