Bonuses and Equity Compensation: RSUs, Options, Vesting, and Real Value

Beyond Base: How Variable Pay Fits Total Compensation

Base salary is only one component of total compensation. Increasingly, bonuses and equity make up a large — sometimes dominant — share of a package, especially at senior levels and in technology, finance, and startups. Evaluating an offer on base alone can be badly misleading in both directions: understating a strong equity grant or overstating a headline number that's mostly at-risk pay.

The professional habit is to translate every offer into expected total compensation, then discount the uncertain parts by how likely they are to actually pay out. A guaranteed base is worth its face value; a target bonus is worth its expected value; illiquid startup equity is worth a probability-weighted fraction of its paper value.

The Main Types of Bonus

• Performance/annual bonus: a target percentage of base (say 15%) paid on individual and company performance; the 'target' is not a guarantee.
• Signing bonus: a one-time payment to join, often with a clawback if you leave within a year.
• Retention bonus: paid to keep you through a critical period, such as an acquisition.
• Spot bonus: a discretionary reward for a specific achievement.
• Commission: variable pay tied directly to sales, governed by a commission plan you should read closely.

The word to scrutinize is 'target.' A 20% target bonus means 20% if targets are fully met — historical payout rates and the clarity of the metrics matter enormously. Ask what the bonus has actually paid over the last few years, not just the headline target.

RSUs: The Most Common Equity Today

Restricted Stock Units are the dominant form of equity at established public companies. An RSU is a promise to give you shares once they vest — typically over four years, often with a one-year cliff (nothing vests until your first anniversary, then it vests monthly or quarterly). Once vested, the shares are yours and are taxed as ordinary income at their value on the vesting date.

Two practical points. First, vested RSUs are effectively cash you chose to hold in one stock — many advisors suggest selling on vest and diversifying, since concentration in your employer's stock compounds career and portfolio risk. Second, RSU value on an offer is a projection based on today's share price; the actual value swings with the market between grant and vest.

Stock Options: Upside With Strings

Stock options give you the right to buy shares at a fixed strike price. They only have value if the share price rises above that strike — if it doesn't, they're 'underwater' and worthless. Options are common at startups, where they represent a bet on growth, and they come in two tax flavors: ISOs (incentive stock options, potential favorable tax treatment but AMT complications) and NSOs (non-qualified, taxed as ordinary income at exercise).

Vesting Is Everything

Equity you haven't vested is a promise, not an asset. The standard four-year vest with a one-year cliff means leaving at month eleven forfeits everything; leaving at month thirteen keeps the first year's worth. This structure exists to retain you, and it should shape the timing of any job change — walking away from a large unvested tranche is leaving money on the table.

When negotiating a new role that requires forfeiting unvested equity at your current job, that forfeiture is a legitimate bargaining chip: ask the new employer to 'make you whole' with a signing bonus or additional grant covering what you're giving up. Employers do this routinely for candidates they want.

How Bonuses and Equity Are Taxed

Bonuses are supplemental wages, commonly withheld at a flat 22% federally (37% above $1 million) plus FICA and state tax. That withholding often exceeds your true marginal rate, so a bonus can look overtaxed at payout even though it's reconciled at filing. RSUs are taxed as ordinary income on the value at vesting; many companies 'sell to cover' by withholding shares, but the default 22% supplemental withholding can under-withhold for high earners, creating an April surprise.

The recurring lesson: don't confuse withholding with your final tax, and don't let tax mechanics drive bad decisions. Turning down a bonus or refusing equity over a withholding misconception is a genuine, avoidable loss.
