Schedule 15-Min Safe Harbor Review

Washington Supplemental Tax Regulations for Meta Platforms RSUs

Washington imposes 0% personal state income tax on W-2 wage income and RSU vests. However, when you subsequently sell shares that have appreciated post-vest, long-term capital gains exceeding $262,000 are subject to the 7% WA Capital Gains Excise Tax.

Washington Safe Harbor & Underpayment Penalties

No state wage safe-harbor required. Only federal 1040-ES applies.

Employer Stock Plan Specifics: Charles Schwab Stock Plan Services

Meta vests quarterly on the 15th of February, May, August, and November. With META trading at elevated fair market values, single quarterly vests can easily exceed $50,000–$100,000. If you do not proactively adjust your supplemental withholding rate in Schwab to 37%, you will owe thousands in underpayment penalties.

When vesting at Meta Platforms, Charles Schwab Stock Plan Services calculates automatic sell-to-cover withholding using Washington's statutory supplemental rate of 0.00% combined with the federal supplemental rate (22% on up to $1M). Because top earners in Washington reach marginal brackets exceeding these rates, you will face an incremental shortfall on April 15.
