Stock Options Explained
Demystifying employee stock options to help you make informed decisions.
ISOs vs NSOs
Understanding the difference between Incentive Stock Options (ISOs) and Non-Qualified Stock Options (NSOs) is crucial for tax planning. ISOs often provide tax advantages but have strict qualification rules, whereas NSOs are more flexible but are taxed upon exercise.
Vesting Schedules
A standard vesting schedule is four years with a one-year cliff. You receive nothing if you leave before one year, but at the one-year mark, 25% of your options vest immediately.
Strike Price & 409A Valuation
The strike price is determined by the company's 409A valuation, which sets the fair market value of common stock. A lower strike price compared to future value means greater potential upside.
Exercise Windows
When you leave a company, you typically have an exercise window (often 90 days) to buy your vested shares. Some companies now offer extended exercise windows.
AMT Implications
Exercising ISOs can trigger the Alternative Minimum Tax (AMT). It's essential to consult a tax professional before making large exercise decisions to understand your potential liability.
Early Exercise and 83(b) Election
If your company allows early exercise, you can buy unvested shares and file an 83(b) election. This can be highly tax-efficient but carries the risk of losing your investment if the company fails.
RSUs vs Options
RSUs are actual shares granted to you that vest over time, while options give you the right to purchase shares at a set price. RSUs are less risky since they have value as long as the stock price is above zero.
Evaluating Equity Offers
Consider the total number of outstanding shares, the company's valuation, and what percentage your offer represents to accurately evaluate equity.
Dilution
As the company raises more funding, new shares are issued, which can dilute your ownership percentage. Focus on the value of your shares rather than just the percentage.
Preferred vs Common Stock
Investors usually receive preferred stock, which has liquidation preferences, while employees get common stock. Understanding the difference helps gauge the true value of your options in an exit scenario.

Use equity calculators to model different exit scenarios and understand potential payouts, keeping in mind strike prices and estimated taxes.
When to Exercise and Tax Strategies
Deciding when to exercise depends on your financial situation, belief in the company, and tax implications. Strategies include exercising early, exercising post-exit, or exercising gradually to manage AMT.
Frequently Asked Questions
What is the difference between ISOs and NSOs?
Incentive Stock Options (ISOs) are generally granted to employees and can offer favorable tax treatment, potentially deferring taxes until the shares are sold. Non-Qualified Stock Options (NSOs) can be granted to employees, contractors, and advisors, and are taxed at both exercise and sale.
What is a typical vesting schedule?
A common vesting schedule is over four years with a one-year cliff. This means you earn 25% of your options after one year of employment, and the rest vest monthly or quarterly over the remaining three years.
What does strike price mean?
The strike price (or exercise price) is the fixed price at which you can buy a share of stock when you exercise your options. It is typically set at the fair market value of the stock when the options are granted.
What is an 83(b) election?
An 83(b) election allows you to be taxed on the value of your shares when they are granted rather than when they vest. This is usually beneficial if you expect the company's valuation to increase significantly, but it requires paying taxes upfront.
How do RSUs differ from stock options?
Restricted Stock Units (RSUs) are a promise to deliver shares at a future date, usually when they vest. Unlike options, you don't have to buy RSUs; they are granted as part of your compensation, and you are taxed when they vest.
