Restricted stock units, commonly called RSUs, are one of the most widely used forms of equity compensation. They are especially common at public companies and later-stage private companies because they are relatively simple to administer and easy for employees to understand compared with stock options.

Restricted stock units (RSUs) are one of the most common forms of equity compensation offered by employers. For a broader explanation of how RSUs compare to stock options, see our stock options and restricted stock guide.

What an RSU Represents

An RSU is a promise from your employer to deliver shares of company stock after certain conditions are met. Most often, that condition is continued employment over a vesting period. Unlike stock options, RSUs do not require you to pay an exercise price to receive the shares.

• The company grants a set number of RSUs.
• The award vests over time or upon performance milestones.
• When vesting occurs, shares are delivered to you.

Because there is no exercise price, RSUs generally retain value as long as the company’s shares have value.

How Vesting Usually Works

Vesting schedules vary, but several patterns are common. You might see annual vesting over four years, quarterly vesting after a one-year cliff, or performance-based vesting tied to specific company goals.

Until the award vests, the shares are not yet yours. If you leave the company early, unvested RSUs are often forfeited unless your plan provides otherwise.

How Taxes Apply to RSUs

In most cases, RSUs are taxed as ordinary income when they vest. The fair market value of the shares delivered at vesting is generally included in your W-2 income for the year.

That means taxes can apply even if you do not sell the stock. Many employers automatically sell some shares to cover withholding, but the default withholding may still fall short for high-income employees.

What Happens After Shares Vest

After vesting, the question shifts from compensation to investment strategy. Once you own the shares, you need to decide whether holding more employer stock makes sense within your overall portfolio.

• Keep the shares if they still fit your risk tolerance and diversification plan.
• Sell some or all of the shares to reduce concentration risk.
• Use proceeds to build a more diversified investment strategy.

Why RSUs Matter in a Financial Plan

RSUs can significantly affect income, taxes, and portfolio concentration. Large vesting events may increase annual income, change cash flow needs, and raise questions about whether too much wealth is tied to one employer.

That is why RSU planning is often connected to broader tax strategy and diversification planning rather than treated as an isolated compensation issue.

Why Employers Like RSUs

Employers often use RSUs because they are easier to communicate than stock options and usually feel more tangible to employees. Since RSUs can still retain value even if the stock price does not soar, they are often viewed as a more stable form of equity compensation.

Why Employees Still Need a Plan

Simplicity should not be mistaken for lack of consequence. Large vesting events can change annual income, tax withholding, and portfolio concentration. If shares continue to accumulate over time, the position can quietly become too large without an intentional strategy.

• Track upcoming vesting dates in advance.
• Estimate how each vesting event affects annual income.
• Decide ahead of time whether shares will be sold, partially sold, or held.

How RSUs Compare With Cash Compensation

Once shares vest, employees sometimes forget that keeping them is a fresh investment decision. Comparing the value to a cash bonus can help clarify the choice. If the company paid the same amount in cash, would you buy more employer stock with it? That question often helps bring investment discipline into the decision.

Common Mistakes Employees Make With RSUs

• Ignoring vesting dates until the tax impact has already occurred.
• Assuming employer withholding will fully cover the tax bill.
• Holding shares automatically without reviewing concentration risk.
• Treating vested shares differently than any other investment decision.

A simple review process before and after each vesting event can help employees avoid these mistakes and make more intentional choices.

Questions to Ask About Your RSU Plan

• How often do shares vest?
• Will taxes be withheld through a sell-to-cover process?
• What is your plan for the shares after vesting?
• How much employer stock do you already own across all accounts?

RSUs and Career Decisions

Because unvested RSUs are often forfeited if employment ends, they can also influence career timing. Understanding future vesting dates can help employees weigh compensation decisions more realistically when considering a role change, promotion, or long-term commitment to the company.

The Bottom Line for Employees Receiving RSUs

The better you understand your vesting schedule, tax treatment, and post-vesting decision process, the more likely RSUs will serve your goals rather than create confusion. A simple plan often goes a long way.
