Washington Supplemental Tax Regulations for Google (Alphabet) RSUs

Washington State levies 0% personal income tax on W-2 wages and ordinary income recognized at RSU vest. However, Washington enforces a 0.58% WA Cares Fund (Long-Term Services and Supports Trust Program) uncapped payroll premium on all W-2 wages and RSU vests unless you hold an approved exemption, plus a 7% Washington Capital Gains Excise Tax on post-vest capital gains exceeding the annual statutory standard deduction.

Washington Bracket Architecture: 0.00% personal wage income tax; 0.58% uncapped WA Cares payroll assessment (unless exempt); 7.0% excise tax on net long-term capital gains above the statutory threshold (~$270,000).

Washington Safe Harbor & Estimated Tax Vouchers (None for wage vests (Federal Form 1040-ES only; WA DOR My DOR portal for 7% Capital Gains Excise Tax))

No Washington state income tax quarterly estimated vouchers are required at vest; however, federal Form 1040-ES quarterly payments remain mandatory to cover the 13%–15% federal supplemental spread.

Multi-State Relocation & Nonresident Sourcing Rules in Washington

Relocating to Washington prior to an RSU vest eliminates state tax on post-relocation service periods, but former residents of California, New York, or Massachusetts remain liable to their departure state for the prorated workday fraction earned prior to establishing Washington domicile.

Employer Stock Plan Specifics: Google (Alphabet) (Charles Schwab / Morgan Stanley)

Google Stock Units (GSUs) follow a frontloaded 33% / 33% / 22% / 12% four-year schedule, vesting monthly on the 25th. While monthly vesting smooths out stock price volatility compared to quarterly cliffs, it creates a silent, compounding tax deficit: every single month, your GSU release is taxed at the 22% flat federal supplemental rate, plus your annual January performance bonus is also withheld at 22%. By December, L5+ Googlers routinely accumulate 12 consecutive months of 10%–15% federal underwithholding.

Withholding Election Guidance: Google allows U.S. employees to adjust their federal supplemental tax withholding rate directly inside Charles Schwab Equity Award Center (under Account Settings -> Tax Withholding Elections). Because GSUs vest monthly, updating your rate to 32%, 35%, or 37% early in Q1 applies to all remaining monthly vests for the calendar year—eliminating the need to mail manual quarterly Form 1040-ES checks.
