RSU (Restricted Stock Unit)

A type of equity compensation that grants you a set number of company shares that vest over time. At vesting, the shares become yours to hold or sell. Common at public tech companies. Taxed as ordinary income at vest.

Restricted Stock Units (RSUs) are a form of equity compensation where the employer promises to grant you a number of company shares that become yours over a vesting schedule. **How RSUs work:** 1. At grant: You're told you'll receive X shares over 4 years 2. At vest: On each vest date (usually quarterly or annually), a portion of shares become yours 3. Taxation: The shares are taxed as ordinary income at the fair market value on the vest date 4. Flexibility: Once vested, you can hold, sell, or gift the shares **The tax consideration:** RSU income is taxable ordinary income — not capital gains. Your brokerage will withhold shares or sell a portion to cover the tax liability. This is automatic at most companies. Make sure you understand what your after-tax RSU income will actually be. **Double-trigger RSUs (private companies):** At private companies, RSUs often have two vesting triggers: (1) time vest and (2) a liquidity event (IPO or acquisition). You don't receive the shares until both conditions are met. If the company never exits, the RSUs never deliver value regardless of how long you've been vesting. **RSU value fluctuation:** Unlike stock options, RSUs have value even if the stock price drops (they can't go 'underwater'). But they're also worth less if the stock price falls from when you joined. Early large grants can become worth much more or much less than expected over a 4-year vest. **Annual refresher grants:** Most large tech companies give annual RSU refresh grants to retain employees whose original grant is mostly vested. These are negotiable and worth asking about.

Why it matters

At many tech companies, RSU income can exceed base salary over the vesting period. Understanding the tax mechanics and vesting schedule is essential for financial planning and for accurately evaluating offers.

Candidate tip

When evaluating an RSU grant, calculate its after-tax value using your expected federal + state marginal tax rate (often 30-40%+) — the number on the offer letter is the gross value, not what you'll actually receive.
