Restricted Stock Units (RSUs) are a form of equity compensation where an employer promises to give you shares of company stock according to a vesting schedule. Unlike stock options, RSUs always have value as long as the company's stock has value, since you don't need to purchase them at a strike price.
How RSUs Work: The Basics
Vesting Mechanics: Most RSU grants follow a vesting schedule that typically includes:
- A cliff period (usually 1 year) before any shares vest
- Periodic vesting (often quarterly) after the cliff
- A total vesting period (commonly 4 years)
For example, if you receive 4,000 RSUs with a 4-year vesting schedule and 1-year cliff:
- After year 1: 1,000 shares vest (25%)
- Years 2-4: 250 shares vest each quarter (6.25%)
Tax Treatment: RSUs incur tax obligations at two key points:
At Vesting:
- RSUs are treated as ordinary income when they vest
- The fair market value of shares on the vesting date is taxable
- Your employer typically withholds some shares for taxes
At Sale:
- If you sell vested shares, you may owe capital gains tax
- Short-term capital gains apply if held < 1 year after vesting
- Long-term capital gains apply if held > 1 year after vesting
Real-World Examples
Example 1: Public Company RSU Grant: Sarah receives 1,000 RSUs at TechCorp when the stock price is $100.
Initial grant value: $100,000
- Vesting schedule: 4 years with 1-year cliff
- After 1 year: 250 RSUs vest when stock is at $120
- Taxable income at vesting: 250 × $120 = $30,000
- Shares withheld for taxes (assuming 30% rate): 75 shares
- Net shares received: 175 shares
Example 2: Pre-IPO Company RSUs: Mike joins StartupX and receives 10,000 RSUs.
- Initial 409A valuation: $5 per share
- Grant paper value: $50,000
- Double-trigger vesting:
- Time-based vesting (4 years)
- Liquidity event (IPO/acquisition)
- If StartupX goes public at $20/share, Mike's vested shares become significantly more valuable
RSU Strategies and Best Practices
