Meta Platforms Equity Plan & Tax Architecture

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.
