Unity Software vesting in Washington
Unity Software runs a quarterly RSU vesting schedule. For Washington residents, each vest is a taxable event: federal supplemental withholding at 22% up to $1M YTD and 37% above, with no state withholding (Washington does not tax wage income), plus Medicare, plus Social Security up to the annual wage base.
The withholding gap
A senior Unity Software engineer earning $300k base plus $400k RSU in Washington sits at a combined marginal rate near 35-37%. 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.
Washington-specific planning moves
Washington has no state income tax, so the tax question on Unity Software RSU sales is purely federal. Compare federal LTCG (15-20%) vs ordinary (up to 37%).
Moving in or out
If you plan to move during an active $Unity Software vesting schedule, trailing-nexus rules apply. Washington has no state income tax to source, so a move in is straightforward; a move out depends on your destination state's rules. Document your move date, work location per pay period, and any remote-work arrangements.
