Employee Stock Options and Taxation Lecture Notes

This set of vocabulary flashcards covers the fundamentals of employee stock options, including the differences between NSOs and ISOs, vesting structures, and the associated tax implications and calculations.

Employee stock options

Essentially long calls that give the employee the right to buy company stock at a fixed price.

Vesting period

The required time period an employee must remain with the company before they are granted the right to exercise their stock options.

Vesting cliffs

A mechanism in stock option plans that releases options in specific chunks after defined time periods, such as $250$ options vesting each year.

Non-qualified stock options (NSOs)

A type of stock option that can be granted to employees, contractors, and consultants, which is generally less tax-advantaged than Incentive Stock Options.

Incentive stock options (ISOs)

Stock options that may only be granted to company employees and offer potential tax advantages where gains are delayed and potentially taxed at lower rates.

Bargain element

Also known as the compensation element or intrinsic value, it is the difference between the market price at exercise and the exercise price, taxed as ordinary income for NSOs.

Intrinsic value

The amount by which the current market price of a stock exceeds the fixed exercise price of an option; calculated as $\text{Market Price} - \text{Exercise Price}$.

Marginal tax bracket

The specific tax bracket applied to the last dollar earned by a taxpayer.

Cost basis (NSOs)

The value used to calculate capital gains/losses upon liquidation, calculated for NSOs as $\text{Exercise price per share} + \text{Intrinsic value per share at exercise}$.

Short-term capital gains

Gains realized from selling a security held for one year or less, which are taxed at the same rates as ordinary income, up to $37\%$.

Long-term capital gains

Gains realized from selling a security held for more than one year, typically taxed at preferential rates of $15\%$ or $20\%\,.$.

ISO Holding Period Requirements

To qualify for long-term capital gains treatment, ISO shares must be sold at least $2\,years$ from the date of the grant and over $1\,year$ from the date of exercise.

Tax event (NSO Exercise)

The moment NSOs are exercised, where the total intrinsic value is added to the employee's taxable income and subject to ordinary income tax rates.

Tax event (ISO Liquidation)

The sole tax event for Incentive Stock Options, assuming holding periods are met, where the gain (Liquidation Price - Exercise Price) is taxed at long-term capital gains rates.
