How are RSUs taxed?
While there are many aspects of stock compensation to consider, let's focus on the key elements that determine how much tax you'll actually pay on your RSUs.
1. Income tax at vesting
When RSUs vest, they're immediately taxed as ordinary income based on their fair market value. Unlike some other forms of stock compensation, there's no way around this - you'll owe taxes as soon as the shares become yours.
To calculate your taxable income, multiply the number of vesting shares by the market price on the vesting date. For example, if 100 RSUs vest when the stock price is $50, you'll have $5,000 in taxable income.
- Taxable Income = Number of Vesting Shares × Market Price at Vesting
Because RSUs are considered supplemental wages, they're subject to specific withholding rates: 22% for the first $1 million of RSU income, and 37% for any RSU income exceeding $1 million.
- Number of Shares Vesting: 100
- Market Price at Vesting: $50/share
- Taxable Income: 100 × $50 = $5,000
- Withholding at 22%: $5,000 × 22% = $1,100
2. Withholding mechanics
Your employer typically handles the tax withholding through share withholding, automatically selling or retaining enough shares to cover your tax obligation.
For example, if you're subject to a 22% federal withholding rate and vest 100 shares worth $50 each:
- Total Value: $5,000
- Withholding Required: $1,100 (22% of $5,000)
- Shares Withheld: 22 shares ($1,100 ÷ $50 per share)
- Net Shares Received: 78 shares
However, this withholding might not cover your entire tax liability, especially if you're in a higher tax bracket.
3. Additional tax considerations
Beyond federal income tax, several other taxes come into play:
- Social Security and Medicare Taxes: RSUs are subject to these payroll taxes, which add 7.65% to your tax liability (up to certain income limits).
- State and Local Taxes: Your tax burden will vary based on where you live and work.
- Alternative Minimum Tax (AMT): While RSUs themselves don’t trigger AMT, the additional income may push you into AMT territory, particularly in high-income years.
4. Capital gains implications
Once your RSUs vest, any subsequent price changes are treated as capital gains or losses. The tax treatment depends on how long you hold the shares after vesting:
- Hold < 1 year: Short-term capital gains (taxed at ordinary income rates)
- Hold > 1 year: Long-term capital gains (maximum 20% tax rate)
Your cost basis for these calculations is the market value of the shares on the vesting date - the same amount that was initially taxed as income.
Taxation Timeline: Vesting → Withholding → Potential Sale → Capital Gains Tax (if held).
Factors affecting your tax rate
There are a few key things that determine how much tax you'll owe on your Restricted Stock Units (RSUs):
Total Income for the Year
The money you make from RSUs gets added to all your other income. This might push you into a higher tax bracket. In 2024, the key thresholds are:
- Married filing jointly: If your income exceeds $731,200, it can raise your tax bracket.
Going over these limits can mean you end up paying a higher percentage in taxes. - Single filers: If your total income goes over $609,350, you’ll be in a higher tax bracket.
Filing Status
How you file your taxes also affects how much you owe. For example, whether you file as single or married changes your tax brackets and what deductions you can take. This will influence how much gets withheld during the year and what you owe at tax time.
When Your RSUs Vest
The timing of when you receive your RSUs is important:
- If multiple RSUs vest in the same year, it could push you into a higher tax bracket.
- If they vest near the end of the year, you might have to make adjustments to your estimated tax payments to avoid penalties.
- There might be lock-up periods when you can’t sell your shares to cover the tax, which means you could need other cash to pay the tax bill.
In simpler terms, the amount of tax you owe on RSUs depends on your total income, how you file your taxes, and when the RSUs become yours. These factors can all affect how much you need to pay and whether you might move into a higher tax bracket.
Understanding Alternative Minimum Tax (AMT) and How Its Related to RSUs
The Alternative Minimum Tax (AMT) is a parallel tax system designed to ensure that individuals and corporations pay at least a minimum amount of tax, even if they qualify for certain deductions and credits under the regular tax system. While AMT is most commonly associated with Incentive Stock Options (ISOs), it’s worth understanding how RSUs might indirectly trigger or affect AMT liability.
Do RSUs Directly Trigger AMT?
Restricted Stock Units (RSUs) do not directly trigger AMT, unlike ISOs, which have specific rules that can result in AMT liability. The reason is simple: RSUs are taxed as ordinary income at the time they vest, and this income is already subject to standard federal income tax. There’s no deferral of income recognition, and therefore no special AMT adjustment for RSUs themselves.
How RSUs Can Indirectly Lead to AMT Liability
Although RSUs themselves do not trigger AMT, the additional income generated when RSUs vest may push taxpayers into higher income levels, making them more susceptible to AMT for the following reasons:
1) Pushing Total Income Above AMT Thresholds
AMT calculations start with your adjusted gross income (AGI) and apply specific adjustments and preference items. When RSUs vest, the taxable value of the vested shares is added to your ordinary income. This higher income level may cross AMT exemption phase-out thresholds, increasing the likelihood of owing AMT.
AMT Exemption Thresholds for 2024:
- Single filers: $81,300
- Married filing jointly: $126,500
- If your income exceeds these amounts, the exemption begins to phase out, increasing your AMT liability.

2) Interaction with Other AMT-Triggered Events
High-income individuals may already be at risk of AMT due to other factors like ISO exercises, large deductions for state and local taxes, or mortgage interest on home equity loans. The additional RSU income could compound these issues, making AMT liability more likely.
3) Loss of Deductions and Credits
Under the AMT system, certain deductions allowed under the regular tax system are disallowed or limited. Examples include state and local tax deductions (SALT) and miscellaneous itemized deductions. The increase in taxable income from RSUs could result in the loss of these deductions, further increasing your AMT exposure.
4) Charitable Giving and RSU Sales
If you donate appreciated RSU shares or sell them to fund charitable contributions, these transactions may interact with AMT rules in ways that are important to plan around.
How RSUs Can Contribute to AMT Liability
Imagine this example: a high-income earner who is already close to the AMT threshold due to regular wages, investment income, and the exercise of ISOs. If this person’s RSUs vest during the year, adding $100,000 in taxable income, the higher income level could:
- Push them into AMT territory by reducing or eliminating the AMT exemption.
- Increase the effective AMT rate applied to their income (26%-28%).
Strategies to Mitigate AMT Risks with RSUs
1) Plan Vesting Dates to Avoid Clustering Income
If possible, time the vesting of RSUs to spread the income over multiple years. This can prevent spikes in income that may lead to AMT exposure.
2) Understand Your Overall Tax Picture
If you also hold stock options or have significant deductions subject to AMT adjustments, consult a tax professional to model different scenarios.
3) Maximize Pre-Tax Contributions
Reduce your taxable income by contributing to pre-tax retirement accounts (401(k), IRA), Health Savings Accounts (HSA), or Flexible Spending Accounts (FSA).
4) Make Estimated Tax Payments
If your employer’s withholding isn’t sufficient to cover your AMT liability, consider making quarterly estimated tax payments to avoid penalties.
5) Leverage Tax-Loss Harvesting
If you sell RSU shares at a loss, these capital losses can offset other gains or reduce taxable income, potentially lowering AMT exposure.
6) Work with a Financial Advisor
AMT can be complex, and RSU taxation adds another layer of intricacy. A financial advisor or tax professional can help you navigate these challenges and optimize your overall tax strategy.

Frequently Asked Questions
About RSU Taxes and Tax Rates
What are Restricted Stock Units (RSUs)?
RSUs are a form of employee compensation where an employer grants company stock that vests over time or upon achieving certain milestones.
When are RSUs taxed?
RSUs are taxed as ordinary income when they vest. Additional taxes, such as capital gains, may apply when the shares are sold.
How do I calculate the tax on my RSUs?To calculate the taxable income at vesting, multiply the number of shares vesting by the stock’s market price at the vesting date. Use the RSU Tax Calculator for detailed estimates.
What is the difference between ordinary income tax and capital gains tax on RSUs?
Ordinary income tax applies at vesting, based on the market value of the shares. Capital gains tax applies to any price changes after vesting and is categorized as short-term (held <1 year) or long-term (held >1 year).
How can I reduce the tax burden on my RSUs?
Strategies include holding shares for more than a year to qualify for long-term capital gains rates, planning vesting schedules, and consulting a financial advisor for tax optimization.
What happens if I sell my RSU shares immediately after vesting?
If you sell immediately, there’s likely no additional capital gain or loss since the sale price equals the cost basis. However, you still owe taxes on the vesting value.
Do RSUs push me into a higher tax bracket?
RSU income is added to your total income, which can push you into a higher tax bracket and increase your overall tax liability.
How do state and local taxes apply to RSUs?
RSUs are subject to state and local taxes based on the location where the income was earned, which varies depending on your employer and residency.
What is share withholding, and how does it affect my RSUs?
Share withholding is when your employer retains or sells enough shares to cover tax obligations at vesting. It reduces the number of shares you receive but simplifies tax payments.
Can RSUs trigger the Alternative Minimum Tax (AMT)?
RSUs themselves don’t typically trigger AMT, but the additional income from RSUs could push you into AMT territory, especially if you also have stock options.
What are the risks of holding RSUs after vesting?
The stock value may decline, which can reduce your overall compensation. Over-concentration in company stock is another risk to your financial portfolio.
What should I do if my employer withholds too little tax on my RSUs?
If the withholding isn’t sufficient, you may owe additional taxes when you file your return. Consider making estimated tax payments or adjusting your withholding.
