How are RSUs taxed?

As you probably know, Restricted Stock Units (RSUs) are a form of equity compensation granted by an employer to an employee in the form of company stock. RSUs are often used as a tool to attract and retain top talent, especially in the tech industry and with startups.

Unlike stock options, RSUs have no exercise price and always have some value to the recipient when they vest. However, they are considered "restricted" because they are subject to a vesting schedule, which means the employee does not receive the shares until certain conditions are met, such as continued employment for a period of time or achievement of specific performance goals.

When RSUs vest, they are considered income and are subject to federal and state income taxes, as well as Social Security and Medicare taxes. The amount of income reported is equal to the fair market value of the shares on the vesting date, multiplied by the number of shares vested.

For example, if an employee is granted 1,000 RSUs that vest over four years and the stock price is $50 on the vesting date, the employee would owe taxes on $12,500 of income (250 shares x $50) for that year.

It's important to note that the taxes owed on RSUs can be significant, especially if the stock price has increased substantially since the grant date. Employees should plan ahead and consider strategies to manage their tax liability, such as selling shares to cover taxes or using a 83(b) election.

Understanding RSU Tax Withholding

When your RSUs vest, your company will typically withhold a portion of the shares to cover the required tax withholding. The two most common methods are:

  1. Net Shares: The company withholds a number of shares equal in value to the tax liability. You receive the remaining shares.
  2. Sell to Cover: The company sells enough shares to cover the tax withholding obligation. You receive the remaining shares and cash from the sale.

Some companies may also offer a cash settlement option, where they pay the taxes in cash and you receive the full number of vested shares.

Supplemental Wage Withholding Rate

RSUs are typically treated as supplemental wages for tax purposes. The IRS flat rate for supplemental wage withholding is 22%. However, if your supplemental wages exceed $1 million in a calendar year, the excess is subject to a 37% withholding rate.

Keep in mind, your actual tax liability may be higher or lower than the amount withheld, depending on your individual tax situation. You may need to make estimated tax payments or adjust your W-4 withholding to avoid underpayment penalties.

"RSUs aren't just a one-time bonus or an annual windfall; they can be a critical part of your long-term financial strategy. The key lies in treating them not as an isolated asset but as an integral part of your broader investment portfolio and financial goals." - UpStock
