Non-Qualified Stock Options (NSOs)

Non-Qualified Stock Options (NSOs)


Non-Qualified Stock Options (NSOs), often referred to as non-statutory stock options, are a type of employee stock option that does not meet specific criteria to qualify for special tax treatment like their counterpart, Incentive Stock Options (ISOs). They are a popular form of compensation provided by employers, allowing employees to benefit from the growth of the company.


How Do NSOs Work?

  1. Grant Date: The date on which the NSOs are offered to an employee.
  2. Exercise Price: The price at which the employee can buy the company's stock, usually set to the stock's fair market value on the grant date.
  3. Vesting Schedule: Outlines when the employee is eligible to exercise their options. Typically, NSOs vest over time to encourage employees to stay with the company.
  4. Expiration Date: The last date on which the options can be exercised.

Tax Implications of NSOs:

Unlike ISOs, the exercise of NSOs leads to immediate tax implications:

  1. At Exercise: The difference between the fair market value of the stock on the exercise date and the exercise price (referred to as the "bargain element" or "compensation element") is treated as ordinary income. This amount is subject to federal, state, and local income taxes, as well as FICA and Medicare taxes.
  2. At Sale: When the stock acquired through the exercise of NSOs is sold, the difference between the sale price and the fair market value on the exercise date is treated as a capital gain or loss. Depending on how long the stock is held, it may be classified as a short-term or long-term capital gain/loss.

Advantages of NSOs:

  1. Flexibility: NSOs can be granted to anyone, not just employees. This makes them versatile for contractors, board members, and other non-employee workers.
  2. No AMT Concerns: Unlike ISOs, there is no risk of triggering the Alternative Minimum Tax (AMT) with NSOs.

Disadvantages of NSOs:

  1. Immediate Tax Implication: Upon exercise, the bargain element is treated as ordinary income, potentially leading to a significant tax bill if the stock has appreciated greatly since the grant date.
  2. No Special Tax Rates: NSOs do not qualify for the long-term capital gains rate upon exercise, as ISOs might.

Considerations for Employees:

  1. Tax Planning: Employees should be aware of the tax implications before exercising NSOs, especially if the stock has significantly appreciated.
  2. Exercise Strategy: Employees might consider exercising options in years where their income is lower, potentially reducing the tax impact.
  3. Holding Period: To qualify for long-term capital gains rates upon selling the stock, employees should hold the stock for more than a year after exercise.


Non-Qualified Stock Options offer a way for companies to compensate and motivate their workforce and other affiliates. While they don't provide the same favorable tax treatment as ISOs, their flexibility and straightforwardness make them a popular choice among many employers. As with any form of compensation, understanding the associated tax implications and planning appropriately is crucial.
