Restricted stock units, or RSUs, are a form of equity compensation that many companies use to reward and retain employees. When an employer grants RSUs, it promises to give you company shares in the future, provided you meet certain conditions. Those conditions often involve remaining with the company for a specified period, although some awards may also depend on performance goals.
Unlike stock options, RSUs do not require you to purchase the shares or decide whether to exercise an option. Once the units vest and settle, you generally receive the shares automatically, less any amount withheld for taxes.
RSUs can become one of the most valuable parts of an executive compensation package. They can also create a tax bill before you have decided whether to keep or sell the stock.
Understanding RSU taxes starts with a simple distinction. The value of your shares is generally taxed as compensation when the units vest and settle. Any later change in value is treated as a capital gain or loss when you sell. The mechanics sound straightforward, but a large vesting event can affect withholding, cash flow, investment concentration, retirement timing, and your broader tax picture.
How Are RSUs Taxed? The Quick Answer
RSUs usually create no federal income tax when your employer grants them. A grant represents a promise to deliver shares or cash in the future, provided you meet the plan’s vesting requirements.
When the RSUs vest and your employer delivers the shares, their fair market value generally becomes ordinary wage income. Your employer reports that income on Form W-2 and withholds federal income tax, Social Security tax, Medicare tax, and any applicable state or local taxes.
When you later sell the shares, the difference between the sale price and your tax basis becomes a capital gain or loss. Your tax basis generally begins with the value already included in your wages when the shares settled.
The Three Stages of RSU Tax Treatment
1. Grant: Usually No Immediate Tax
A grant tells you how many units you may receive and the conditions you must satisfy. Because you do not yet own the shares and can still forfeit the award, the grant itself usually does not create taxable income.
2. Vesting and Settlement: Ordinary Income
The largest tax event usually occurs when the RSUs vest and settle. Suppose 1,000 RSUs settle when the stock trades at $50 per share. Your employer would generally report $50,000 of wage income, even if you keep every net share after withholding.
Your company may withhold shares, sell shares, or collect cash for taxes. The method affects the shares you receive, but not the compensation income.
Some plans separate the vesting date from the settlement or delivery date. Review the award documents rather than assuming that the vesting date always determines the taxable value.
3. Sale: Capital Gain or Loss
After settlement, you own the shares. Any change in value from your tax basis creates a capital gain or loss when you sell.
Assume your basis is $50 per share. If you later sell 1,000 shares for $58 each, you generally recognize an $8,000 capital gain. If you sell them for $47 each, you generally recognize a $3,000 capital loss.
The holding period generally begins when the shares are delivered. A sale after more than one year may qualify for long-term capital gain treatment. A sale within one year generally produces a short-term gain or loss. Higher-income taxpayers should also consider whether the 3.8% Net Investment Income Tax may apply to post-settlement gains.
Why RSU Withholding May Be Lower Than Your Actual Tax
One of the most common surprises with RSU stock tax is the gap between withholding and the final tax liability.
Employers often treat RSU income as supplemental wages. For 2026, the optional flat federal withholding rate on supplemental wages remains 22% until an employee’s supplemental wages from that employer exceed $1 million for the year. The mandatory rate on the excess is 37%. Many executives face a marginal federal rate above 22%, so the amount withheld at vesting may not cover the actual tax.
Payroll taxes also reduce the net shares you receive. Social Security tax applies until annual wages reach the taxable maximum, which is $184,500 in 2026. Medicare tax has no wage cap, and an additional 0.9% Medicare tax may apply above filing-status thresholds. Employers begin withholding that additional tax once wages they pay exceed $200,000.
A large vesting event can create a shortfall even when your company sells shares for taxes. Additional withholding or estimated payments may help. Federal safe-harbor rules can reduce penalty exposure, but they do not eliminate the tax due.
Whether you hold or sell your shares, each vesting event can influence your tax strategy, portfolio diversification, and long-term financial goals. Coordinating those decisions can help reduce unnecessary risk and improve flexibility.
How You Could Pay Tax Twice on an RSU Sale
When RSUs vest, their value is generally taxed as ordinary income. If you later sell the shares, only the change in value after vesting should generally be treated as a capital gain or loss.
The problem is that brokerage tax forms do not always show the full cost basis for RSU shares. If that information is not reviewed carefully, your tax return may treat part of the value already taxed as income as an additional capital gain. In effect, you could pay tax twice on the same compensation.
This is not how RSUs are intended to be taxed, but it is an easy issue to miss, particularly when you have several grants, vesting dates, or stock sales. A qualified tax professional should review your employer and brokerage records together before the return is filed. Coordinating that review with your financial advisor can also help ensure the sale fits within your broader tax and investment strategy.
Should You Sell RSUs When They Vest?
Tax treatment should inform the decision, but your financial plan should guide it.
Once RSUs settle, consider the event as though you received a cash bonus and immediately used the after-tax amount to buy your employer’s stock. Would you make that investment today if the same amount arrived in cash?
Holding may fit when the position remains modest, you have strong liquidity, and the risk aligns with your investment strategy. Selling some or all of the shares may make more sense when employer stock already represents a large part of your portfolio, future RSUs will continue to vest, or your salary, benefits, pension, and career prospects depend on the same company.
For executives approaching retirement, concentration deserves special attention. A setback at the employer can affect both employment income and investment wealth. A written diversification policy can replace an emotional decision with a repeatable process.
Coordinate RSU Taxes With the Rest of Your Financial Plan
A vesting calendar should sit beside your tax projection, retirement income plan, and investment policy. Decisions made in isolation can create pressure elsewhere.
Projected vesting income may affect charitable gifts, Roth conversions, portfolio rebalancing, and the timing of major purchases. Planning before the vesting date gives you more time to evaluate the tax obligation, available cash, and the appropriate level of employer-stock exposure.
A Practical RSU Planning Checklist
- Build a vesting calendar with expected dates, estimated values, and the company’s withholding method.
- Estimate total annual income, including salary, bonus, RSUs, investment income, and other taxable items.
- Compare projected tax with expected withholding and estimated payments before the shares vest.
- Set a target range for employer-stock exposure and decide how each vesting event will support it.
- Keep vesting confirmations, W-2 forms, 1099-B forms, and stock-plan statements for basis review.
Bring RSU Tax Decisions Into One Coordinated Strategy
The tax treatment of RSUs follows a clear framework, but a large award can affect more than one tax return. Withholding, cash needs, portfolio concentration, retirement timing, and future vesting events all influence the best course of action.
If RSUs are a meaningful part of your compensation, evaluate them within the rest of your financial plan.

Make Your Next RSU Vesting Event Part of a Broader Strategy.
A significant RSU award can affect far more than your tax return. Decisions about withholding, diversification, cash flow, and when to sell should work together with your broader financial goals, not happen in isolation.
Whether you’re approaching your first vesting event or managing ongoing equity compensation, a coordinated strategy can help you make more informed decisions and avoid costly surprises.
Frequently Asked Questions About RSU Taxes
Are RSUs taxed when granted?
Usually, no. RSUs generally become taxable when they vest and settle, because that is when the employee receives the shares or cash and recognizes compensation income.
Are RSUs taxed as ordinary income?
The value delivered at settlement is generally taxed as ordinary wage income. Any later appreciation or decline is generally treated as a capital gain or loss when the shares are sold.
Is selling RSUs immediately after vesting taxable?
Yes, the sale still must be reported. When the sale price is close to the settlement value, however, the capital gain or loss may be small. The compensation tax arose at settlement.
