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.

Equity (Job Offer)
Offers & NegotiationOwnership stake in the company provided as part of compensation — typically as stock options or RSUs. Equity can be worth far more than base salary at successful companies, but it carries risk and illiquidity, particularly at private companies.
Vesting Schedule
Offers & NegotiationThe timeline over which an employee earns their equity grant. The most common structure is 4 years with a 1-year cliff — meaning no equity is earned in year 1, then 25% vests at 12 months, with monthly or quarterly vesting for years 2-4.
Stock Options
Offers & NegotiationThe right to purchase company stock at a predetermined price (the strike price) at some future time. Common at startups. Options have value when the stock price rises above the strike price — but are worth nothing if the company doesn't grow or exit.
Total Compensation
Offers & NegotiationThe full value of everything an employer provides — base salary, bonus, equity, benefits, retirement contributions, and perks. Comparing total compensation across offers is more accurate than comparing base salaries alone.
Signing Bonus
Offers & NegotiationA one-time cash payment made at the start of employment, used to attract candidates or compensate for benefits being left behind. Often comes with a clawback clause requiring repayment if you leave within 12-24 months.
