RSU Cost Basis Explained: How It Affects Your Tax Planning

By: AJ Ayers, CFP®

Summary:

RSUs are taxed as ordinary income at vesting and as capital gains when sold, with cost basis being the fair market value at vesting, and strategic planning with a financial advisor can optimize taxation and investment decisions.

Imagine you're a new grad software engineer, and you've just been offered a jaw-dropping median RSU value of $300,000 over 4 years at a top tech company.

Sounds like a dream, right? But do you know how to calculate the cost basis of these RSUs? Or that the median estimated tax withholding rate on RSU vesting events is around 40%?

If these numbers are making your head spin, don't worry. In this article, we'll break down these complex terms to help you make the most of your equity compensation.

RSUs, or Restricted Stock Units, are a form of equity compensation that companies grant to employees. They represent the promise of company stock at a future date based on meeting certain conditions, such as remaining employed for a set period or achieving specific performance goals.

Understanding the taxation of RSUs is essential for employees who receive this type of compensation. RSUs are subject to tax when they vest, meaning the employee has earned the right to receive the shares. At this time, the market value of the RSU shares is considered ordinary income and will be taxed at the employee's ordinary income tax rate.

It's important to note that the market value becomes the cost basis for the shares going forward.

For example, let's say you're granted 100 RSUs with a vesting schedule of 25% a year over four years. In year one, when 25 RSUs vest, the market value of those shares is $50 each. The taxable income on those shares is $1,250 (25 * $50), and you'll pay taxes based on your ordinary income tax rate.

Working with a financial advisor can help you make the most of your RSU compensation. They can help you determine when to sell the shares and manage any potential long-term capital gains.

If you hold the shares for more than a year after vesting, the gain from the sale will be taxed at long-term capital gains rates, which are typically lower than ordinary income tax rates.

Cost basis, in simple terms, is the original value of an asset for tax purposes. For RSUs, this would be the value of the stock on the date it vests. The cost basis is important because it's used to determine the capital gain or loss when you sell your shares, which impacts your tax obligations.

Several factors can affect the cost basis of your RSUs:

  • Stock price: The price of the stock on the vesting date directly impacts your cost basis.

  • Number of shares: The more shares you receive, the higher your cost basis will be.

  • Value of the stock: This is the total value of the stock based on the number of shares and stock price on the vesting date.

To calculate the cost basis for your RSUs, follow these steps:

  1. At the time your RSUs vest, note the stock price and number of shares. Keep in mind that your employer might withhold a portion of your shares for tax purposes, so the accurate number of shares might be adjusted after taxes.

  2. Multiply the number of shares by the stock price on the vesting date. This will give you the value of the stock.

  3. Because RSUs are considered income, the value of the stock on the vesting date is usually included in your taxable income. Your adjusted cost basis will be the value of the stock minus any tax withholding.

For example, let's say you receive 100 RSUs and the stock price on the vesting date is $50. You have a total stock value of $5,000. If your employer withholds 30% for taxes ($1,500), your adjusted cost basis would be $3,500.

Planning for RSU Taxation

RSUs are awarded by tech companies and other corporations as part of their compensation packages, and understanding how to handle the taxes associated with them can save you a significant amount of money come tax season.

First and foremost, it's essential to recognize that RSUs are generally taxed as ordinary income.

This means that as your RSUs vest, the value of the shares at the time of vesting will be considered part of your income and will be subject to the applicable income tax rates. To avoid any surprises when filing your tax return, you'll want to proactively estimate the potential tax liability on the vested shares and set aside funds to cover it.

One strategy to consider when managing RSUs taxation is to work with a trusted financial advisor who can help optimize your tax situation. Financial advisors can guide you through the complexities of incorporating RSUs into your overall tax planning and help you make informed decisions about when to sell the shares.

Long-term and short-term capital gains tax rates also come into play when discussing RSUs.

If you decide to hold onto your vested shares and sell them at a later date, any appreciation in the stock's value from the time of vesting to the sale will be subject to capital gains tax. If you hold the shares for more than a year, you will be subject to the more favorable long-term capital gains tax rates.

On the other hand, if you sell the shares within a year, the profit will be considered short-term capital gains and will be taxed at the higher ordinary income tax rates.

Remember that as RSUs vest, you may also have the option to make use of tax withholding to cover your income tax liability on the shares.

Handling RSU Vesting and Tax Reporting

When it comes to RSUs (Restricted Stock Units), understanding the vesting schedule and tax implications is crucial. We're here to help break it down for you and guide you through the process.

As RSUs vest, they are converted to actual shares of stock, which you own outright. The time of vesting varies depending on your company's policies and your employment agreement, but it's common to see vesting schedules that span over a few years, with a portion of RSUs vesting each year or quarter.

Once your RSUs vest, it's time to talk taxes. The value of your vested RSUs is considered taxable income and will be reported on your W-2 form.

The amount included in your income is based on the fair market value of the shares at the time of vesting. Keep in mind that your employer is required to withhold taxes upon vesting, typically at your federal tax bracket's rate.

But wait, there's more.

When you eventually sell your shares, you may need to report any capital gains or losses on your tax return. You can obtain this information from the Form 1099-B provided by your brokerage. The cost basis for these shares should be the fair market value at the time of vesting, as reported on your W-2.

It's important to stay on top of your RSU vesting schedule and be prepared for the tax implications that come with it.

Missing a vesting date or not handling the tax reporting correctly can lead to costly mistakes.

Maximizing RSU Benefits

Receiving RSUs can be an exciting and lucrative element of an employee's compensation package. To make the most of this opportunity, it's essential to understand how these stock grants work and employ an RSU strategy that maximizes their benefits. We'll discuss some essential considerations to help sophisticated professionals optimize their RSU investments. 

One essential aspect of RSUs is their vesting schedule. A typical vesting schedule might permit an employee to gain access to a portion of their granted stock each month or year. Employees should understand their vesting schedule to accurately time when they can sell the shares acquired. The market price of the stock at the grant date has a significant impact on the value of these shares to the employee.

By staying informed about the company's stock price and potential market movements, employees can make better decisions regarding when to sell their shares. In this situation, seeking the advice of a trusted financial advisor could be beneficial.

Employees receiving RSUs should recognize that the value of these shares is directly tied to the success of the company. This implies that a diversified investment portfolio is crucial. When RSUs vest, it's crucial to consider the overall composition of one's investment holdings and make decisions accordingly.

Finally, it's essential to know the tax implications of RSUs. When the stock vests, the employee may have to pay income taxes based on the stock price at the time.

Again, working with a knowledgeable financial advisor can go a long way in making the right decisions for each individual's unique financial situation.
