Employer Stock Plan Specifics: Morgan Stanley at Work (Shareworks) / Fidelity
Amazon equity packages are heavily backloaded into years 3 and 4 (40% each year). In year 3, your total W-2 income can leap into the 37% marginal bracket, while Morgan Stanley only withholds 22% federally. Without quarterly estimated payments or selling additional shares, Amazonians face a $15,000–$40,000 tax shock in April.
When vesting at Amazon, Morgan Stanley at Work (Shareworks) / Fidelity calculates automatic sell-to-cover withholding using Virginia's statutory supplemental rate of 5.75% combined with the federal supplemental rate (22% on up to $1M). Because top earners in Virginia reach marginal brackets exceeding these rates, you will face an incremental shortfall on April 15.
