What is Restricted Stock (RSU/RSA) Tax?
Restricted Stock Units (RSUs) and Restricted Stock Awards (RSAs) are forms of equity compensation given to employees. Unlike stock options, with RSUs and RSAs, you typically don't pay a strike price to acquire the shares. Instead, they are "restricted" until certain conditions are met, usually related to continued employment over a vesting period. Once these restrictions lapse (i.e., the stock vests), they become taxable events.
The taxation of restricted stock is a two-phase process:
- Ordinary Income Tax at Vesting: When your RSUs vest or your RSAs vest (if you didn't make an 83(b) election), the fair market value (FMV) of the shares at that time is considered ordinary income. This amount is added to your wages and is subject to federal income tax, state income tax (if applicable), Social Security (FICA), and Medicare taxes.
- Capital Gains Tax at Sale: If you hold the shares after vesting and then sell them later, any appreciation or depreciation in value from the vesting date to the sale date is subject to capital gains tax. This can be short-term (if held for one year or less after vesting) or long-term (if held for more than one year after vesting).
This calculator is designed for anyone receiving restricted stock compensation, from entry-level employees to executives. It helps clarify the immediate and potential future tax burdens, which can often be a source of confusion.
Restricted Stock Tax Formula and Explanation
Understanding the core formulas is key to managing your restricted stock tax liability. The primary tax event occurs at vesting, where the value of your shares is treated as ordinary income.
Ordinary Income Tax Calculation
The amount subject to ordinary income tax depends on whether you have RSUs, or RSAs with or without an 83(b) election:
- For RSUs or RSAs without an 83(b) election:
Ordinary Income Taxable Amount = Number of Shares Vested × Fair Market Value (FMV) per Share at Vesting - For RSAs with an 83(b) election:
Ordinary Income Taxable Amount = Number of Shares Vested × (FMV per Share at Grant - Grant Price per Share)
(Note: The 83(b) election shifts the ordinary income taxable event from vesting to the grant date, based on the FMV at grant. If FMV at grant equals grant price, the taxable amount is zero at grant.)
Once the Ordinary Income Taxable Amount is determined, the total estimated tax is calculated:
Total Ordinary Income Tax = Ordinary Income Taxable Amount × (Federal Rate + State Rate + FICA Rate + Medicare Rate)
Capital Gains Tax Calculation (if shares are held)
If you hold your shares after vesting and sell them later, you'll calculate capital gains or losses:
Cost Basis per Share = FMV per Share at Vesting (for RSUs/RSAs without 83(b))
Cost Basis per Share = FMV per Share at Grant (for RSAs with 83(b))
Total Capital Gain/Loss = (Future Sale Price per Share - Cost Basis per Share) × Net Shares Remaining After Withholding
Capital Gains Tax = Total Capital Gain/Loss × Long-Term Capital Gains Tax Rate (assuming shares are held over one year after vesting/grant for long-term treatment)
Our calculator simplifies these complex calculations, providing you with a clear estimate.

Practical Examples of Restricted Stock Taxation
Example 1: RSU Vesting and Immediate Sale
Sarah has 100 RSUs vesting. The FMV at vesting is $75 per share. She does not have an 83(b) election (as it's an RSU). Her combined ordinary income tax rate (federal, state, FICA, Medicare) is 35%. She chooses to sell enough shares to cover taxes and then sell the remaining shares immediately.
- Total Value at Vesting: 100 shares * $75/share = $7,500
- Ordinary Income Taxable Amount: $7,500 (since it's an RSU)
- Estimated Ordinary Income Tax: $7,500 * 35% = $2,625
- Shares Withheld for Tax: $2,625 / $75/share = 35 shares
- Net Shares Remaining: 100 - 35 = 65 shares
- Net Cash After All Taxes (Immediate Sale): 65 shares * $75/share = $4,875
In this scenario, Sarah pays $2,625 in ordinary income taxes and walks away with $4,875 cash.
Example 2: RSA Vesting with 83(b) Election and Future Sale
David received 200 RSAs and made an 83(b) election. At grant, the FMV was $20 per share, and he paid a grant price of $0.10 per share. His ordinary income tax rate at grant (when 83(b) applies) was 30%. Now, three years later, the shares have vested, and the FMV at vesting is $100 per share. He holds the shares for another year and sells them when the FMV is $120 per share, incurring a 15% long-term capital gains tax.
- Ordinary Income Taxable Amount (at Grant due to 83(b)): 200 shares * ($20 - $0.10) = $3,980
- Estimated Ordinary Income Tax (paid at grant): $3,980 * 30% = $1,194
- Cost Basis per Share (for capital gains): $20 (FMV at Grant due to 83(b))
- Total Value at Vesting: 200 shares * $100/share = $20,000 (This value is not taxed as ordinary income at vesting due to 83(b))
- Net Shares Remaining After Withholding: 200 shares (assuming taxes were paid out of pocket or from other sources at grant)
- Total Capital Gain: ( $120/share - $20/share ) * 200 shares = $20,000
- Estimated Capital Gains Tax: $20,000 * 15% = $3,000
- Net Cash After All Taxes (Future Sale): (200 shares * $120/share) - $3,000 (capital gains) - $1,194 (ordinary income tax paid at grant) = $24,000 - $3,000 - $1,194 = $19,806
David paid $1,194 in ordinary income taxes at grant and $3,000 in capital gains taxes later, resulting in $19,806 net cash.

Key Factors That Affect Restricted Stock Taxation
Several variables significantly influence the tax outcome of your restricted stock. Understanding these can help you better plan your financial strategy:
- Fair Market Value (FMV) at Vesting: This is arguably the most critical factor for RSUs and RSAs without an 83(b) election. A higher FMV at vesting means a larger ordinary income taxable amount and thus higher immediate tax.
- 83(b) Election for RSAs: For RSAs, filing an 83(b) election within 30 days of the grant date can drastically change your tax picture. It allows you to pay ordinary income tax on the FMV at grant (minus any purchase price) rather than at vesting. If the stock price is expected to rise significantly, this could lead to lower overall taxes by converting potential ordinary income into capital gains.
- Your Marginal Income Tax Brackets: The federal and state income tax rates you fall into will directly determine the percentage of your ordinary income taxable amount that goes to taxes. Higher income earners face higher marginal rates.
- FICA and Medicare Taxes: These payroll taxes apply to the ordinary income portion of your restricted stock, up to certain limits for FICA. They are generally fixed percentages and can add a substantial amount to your overall tax bill.
- Holding Period (Short-term vs. Long-term Capital Gains): If you hold shares after vesting, the time until you sell them matters. Selling within one year of vesting/cost basis establishment results in short-term capital gains, taxed at your higher ordinary income rate. Holding for over a year qualifies for lower long-term capital gains rates.
- Future Stock Price Fluctuation: For shares you hold after vesting, the ultimate sale price relative to your cost basis (FMV at vesting or grant with 83(b)) dictates your capital gain or loss, impacting your final net cash.
- Company Withholding Policies: Most companies have a "sell to cover" policy, automatically selling a portion of your vested shares to cover the ordinary income tax liability. This reduces the number of shares you receive but simplifies tax payment.
Frequently Asked Questions About Restricted Stock Taxes
A: The primary difference lies in the 83(b) election. RSUs are always taxed as ordinary income at vesting. RSAs can be taxed at vesting (like RSUs) or, if an 83(b) election is made, they can be taxed at grant based on the FMV at grant. RSAs often involve a nominal purchase price, while RSUs typically do not.
A: An 83(b) election allows you to pay ordinary income tax on the fair market value (FMV) of your restricted stock (less any amount paid) at the grant date, rather than waiting until it vests. If the stock appreciates significantly between grant and vesting, this can be beneficial as future appreciation is taxed as potentially lower long-term capital gains, rather than higher ordinary income. However, if the stock declines or you forfeit it, you won't get a refund for the taxes paid at grant.
A: No, these are distinct dates. The grant date is when your restricted stock is officially awarded to you. The vesting date is when the restrictions are lifted, and the shares officially become yours, typically after a period of employment.
A: Your cost basis for tax purposes is generally the fair market value (FMV) of the shares on the date the ordinary income tax event occurs. For RSUs or RSAs without an 83(b) election, this is the FMV at vesting. For RSAs with an 83(b) election, it's the FMV at grant (plus any amount paid).
A: Companies typically withhold a portion of your vested shares to cover the estimated ordinary income tax liability (federal, state, FICA, Medicare). This is done to meet payroll tax obligations and is often called "sell to cover" or "net settlement." It prevents you from having to pay a large tax bill out of pocket immediately.
A: Yes, the calculator allows you to input your specific federal, state, FICA, and Medicare tax rates. It's important to use rates that reflect your individual income and filing situation, as these can vary significantly.
A: This calculator is designed for a single vesting event. If you have multiple vesting dates, you should use the calculator separately for each vesting event to get an accurate picture of each tax impact. Each vesting event is a distinct ordinary income taxable event.
A: No, this calculator provides estimates based on standard income tax rules and does not account for complex scenarios like the Alternative Minimum Tax (AMT), which can apply to certain high-income earners or specific stock transactions. For comprehensive planning, consult a qualified tax advisor.
