How Amazon’s 5/15/40/40 Vesting & Cash Bridge Actually Work
Most Silicon Valley companies grant RSU Company shares promised to you that vest over a set schedule. The moment they vest, their full market value counts as taxable paycheck income. on an even 25% / 25% / 25% / 25% annual schedule. Amazon intentionally back-loads its equity grants into a 5% / 15% / 40% / 40% cadence to incentivize retention past the 24-month mark. Because 5% of your stock grant in Year 1 and 15% in Year 2 would leave your pay uncompetitive, Amazon bridges the gap with a two-part Cash Sign-On Bonus paid out across your first 24 paychecks.
Why Employees Hit the Year 3 Compensation Cliff
- Built-In Stock Growth Assumptions: Historically, recruiters size your initial 4-year RSU grant assuming the stock price will appreciate each year. If the stock trades sideways or drops during your first 24 months, your 40% RSU vest in Year 3 may fall short of the Year 2 cash bonus + 15% RSU combination it was meant to replace.
- Fixed Share Count Conversion: Your dollar grant is converted into a fixed number of shares near your start date. If you join near a market peak, you lock in a high conversion price and fewer shares, amplifying any Year 3 shortfall if the stock pulls back.
- Statutory 22% Supplemental Withholding Trap: Unless you elect a higher withholding rate, brokerage custodians typically withhold only 22% federal tax on RSU vests under $1 million. If your total comp places you in the 32%, 35%, or 37% federal bracket, you can face a surprise April tax bill unless you set aside the marginal difference.
Frequently Asked Questions
How does Amazon’s 5/15/40/40 RSU vesting schedule work? ▼
Unlike standard tech companies that vest 25% of your Restricted Stock Units (RSUs) each year, Amazon uses a back-loaded schedule: 5% vests at the end of Year 1, 15% vests at the end of Year 2, 40% vests in Year 3 (typically 20% every 6 months), and the final 40% vests in Year 4 (20% every 6 months).
What is the Amazon Year 3 bonus cliff? ▼
To make up for the 5% and 15% RSU vests in Years 1 and 2, Amazon pays large Year 1 and Year 2 cash sign-on bonuses. In Year 3, those cash sign-on bonuses drop to $0 and your compensation relies entirely on your 40% RSU tranche. If Amazon’s stock price is flat or down since your hire date, your total compensation can drop noticeably in Year 3.
How is my initial Amazon RSU grant share count calculated? ▼
Your offer letter specifies a target dollar grant value, which is converted into a fixed number of RSU shares near your start date using the 30-day average stock price. Once converted into shares, your Year 3 and Year 4 payouts float 100% with the market price of Amazon stock.
How are Amazon RSUs and sign-on bonuses taxed in Washington vs. California? ▼
Both cash sign-on bonuses and vesting RSUs are taxed as W-2 ordinary income on the day they vest or pay out. In Washington state, there is 0% state income tax on salary, bonuses, and RSU vests (Washington’s 7% excise tax only applies to long-term capital gains above $270,000 when selling held shares). In California, vesting RSUs and bonuses face up to 13.3% state ordinary income tax on top of federal brackets.
