RSUs and Stock Options for Executives

For executives at public and pre-IPO companies, equity compensation often represents a significant portion of total wealth. Restricted stock units (RSUs), incentive stock options (ISOs), and non-qualified stock options (NSOs) are all common forms of equity pay, and each comes with its own set of rules around vesting, taxation, and risk management. Understanding these instruments is critical to making informed decisions about your financial future.

RSUs: Taxation at Vesting

RSUs are a promise from your employer to deliver shares of company stock once certain conditions are met, typically a time-based vesting schedule. When RSUs vest, the fair market value of the shares on the vesting date is treated as ordinary income and subject to federal and state income tax, as well as FICA taxes. Many employers withhold shares at vesting to cover the tax, but the default withholding rate may not be sufficient for high earners, potentially leading to an unexpected tax bill at filing time.

Stock Options: ISOs vs. NSOs

Non-qualified stock options (NSOs) are taxed as ordinary income on the spread between the exercise price and the fair market value at the time of exercise. Incentive stock options (ISOs) receive more favorable tax treatment: there is no regular income tax at exercise, but the spread is a preference item for the alternative minimum tax (AMT). If you hold the shares for at least one year after exercise and two years after the grant date, any gain at sale is taxed at long-term capital gains rates.

Managing Concentration Risk

One of the biggest risks executives face is holding too much wealth in a single stock. A common rule of thumb is that no single position should represent more than 10% to 15% of your investable assets. Developing a systematic plan to diversify, whether through scheduled sales, 10b5-1 plans, or hedging strategies, is essential. The decision to hold or sell should be based on your overall financial plan, not on sentiment about your company.
