What is the capital gains tax rate for stock options and RSUs?

Understand the capital gains tax rate applicable to stock options and RSUs as part of employee equity taxation.


The capital gains tax rate for stock options and restricted stock units (RSUs) depends on several factors, including the type of stock options, the duration of ownership, and the specific tax laws in your country. Here's an overview of how capital gains taxes may apply to stock options and RSUs in the United States, which is a common scenario:

1. Incentive Stock Options (ISOs):

  • In the United States, when you exercise ISOs and hold the acquired shares for at least two years from the grant date and one year from the exercise date, the gains from the sale of those shares are typically taxed at long-term capital gains rates.
  • Long-term capital gains rates for individuals can be lower than ordinary income tax rates, depending on your income level., long-term capital gains rates ranged from 0% to 20%, with an additional 3.8% Net Investment Income Tax (NIIT) for high-income earners.

2. Non-Qualified Stock Options (NSOs) and RSUs:

  • Gains from the exercise of NSOs or the vesting and sale of RSUs are generally taxed as ordinary income at your regular income tax rates in the year of exercise or vesting.
  • When you subsequently sell the shares acquired through NSOs or RSUs, any additional gain may be subject to capital gains tax, with the rate based on your holding period. If the shares are held for more than one year from the exercise or vesting date, the gain may qualify for long-term capital gains rates.

3. Short-Term vs. Long-Term Holding Period:

  • Short-term capital gains rates typically apply to assets held for one year or less, and they are taxed at your ordinary income tax rates.
  • Long-term capital gains rates apply to assets held for more than one year, and they are subject to lower tax rates.

4. Stock Option Timing:

  • Timing can significantly impact your tax liability. If you exercise stock options and immediately sell the shares, the resulting gain is generally considered short-term and taxed accordingly. Holding the shares for a longer period can potentially qualify you for lower long-term capital gains rates.

5. Alternative Minimum Tax (AMT):

  • Be aware of the Alternative Minimum Tax (AMT) if you have ISOs. Exercising ISOs can trigger AMT liability in the year of exercise, which can affect your overall tax calculations.

It's important to note that tax laws and rates can change over time, so it's essential to consult the latest tax regulations and work with a tax professional or advisor who can provide guidance based on your specific situation. Tax treatment of stock options and RSUs may vary by country, and the above information primarily applies to the United States. Other countries have their own rules and rates for taxing these types of equity-based compensation.

Employee stock options (ESOs)

When you exercise an ESO, you are taxed on the difference between the fair market value of the stock on the date of exercise and the amount you paid for the stock (usually the strike price). This difference is considered ordinary income, and you will be taxed on it at your ordinary income tax rate.

Restricted stock units (RSUs)

When you vest in an RSU, you are taxed on the fair market value of the stock on the date of vesting. This is considered ordinary income, and you will be taxed on it at your ordinary income tax rate.

Special rules for qualifying ESOs and RSUs

If you meet certain requirements, you may be eligible to defer paying taxes on your ESOs and RSUs until you sell the stock. These requirements are known as the qualified disposition requirements.

To qualify for the special tax treatment, you must:

  • Hold the stock for at least two years after the date of grant and
  • Hold the stock for at least one year after the date of exercise or vesting.

If you meet the qualified disposition requirements, you will pay capital gains tax on the difference between the sale price of the stock and the amount you paid for the stock (usually the strike price or zero) when you sell the stock.

If you do not meet the qualified disposition requirements, you will be taxed on the fair market value of the stock on the date of exercise or vesting as ordinary income.

Tax strategies for ESOs and RSUs

There are a number of tax strategies that you can use to minimize your tax liability on ESOs and RSUs. One strategy is to exercise your ESOs and vest your RSUs as soon as possible. This will allow you to start the holding period required to qualify for the special tax treatment.

Another strategy is to sell your ESO shares and RSU shares as soon as you qualify for the special tax treatment. This will allow you to lock in the capital gains tax rate and avoid paying any additional taxes if the stock price increases in the future.

It is important to consult with a tax advisor to develop a tax strategy that is right for you.
