📘 RSU Tax Essentials
🔹 Withholding Gap
RSUs are often withheld at a flat 22% for federal taxes, but your actual rate may be much higher — plan ahead.
🔹 Vesting = Income
When RSUs vest, the fair market value is treated as ordinary income, subject to income tax and FICA.
🔹 Quarterly Estimates
If your withholding is insufficient, you may need to make estimated tax payments to avoid penalties.
🔹 State Taxes
Don’t forget state income tax — rates vary widely, and some states tax RSU income heavily.

Direct Answer: How Does an RSU Tax Calculator Work?
An RSU tax calculator estimates your total tax liability from restricted stock units in two steps. First, it calculates the ordinary income tax on the fair market value of your shares on the vesting date—this amount is added to your salary and taxed at your regular income tax rate.
Second, if you plan to sell your shares later, it calculates the capital gains tax on any increase in value above the vesting price. The calculator combines both to show your total estimated tax bill.
What Is an RSU Tax Calculator?
An RSU Tax Calculator is a free online tool that helps you estimate the taxes you’ll pay on your restricted stock units. RSUs are a common form of equity compensation, especially in tech companies. But many employees are surprised by the tax bill when their shares vest.
Here’s the key: when your RSUs vest, the full fair market value of the shares is treated as ordinary income—just like a cash bonus. Then, if you sell the shares later for a profit, you may owe capital gains tax on the increase.
Our RSU stock tax calculator does all the math for you. It shows your total tax liability in seconds, so you can plan ahead and avoid surprises at tax time.

Why Use This Tool?
RSU taxation is confusing. There are two separate tax events, different rates, and complex rules. Many employees end up overpaying or underpaying their taxes.
Our RSU stock tax calculator simplifies everything. It’s built for regular people—not tax experts. You don’t need to know tax laws or do complicated math. Just enter your numbers and get clear, actionable results.
Plus, it’s completely free. No credit card, no trial, no catches.
Real-World Example
Meet Sarah. She works at a tech company and receives 500 RSUs that vest on June 1, 2026. The stock price on that day is $100, so her vesting value is $50,000. Her salary is $120,000, and she files as single in California.
Our calculator shows:
- Ordinary income tax on the $50,000 vesting value: ~$14,000
- If she sells immediately, no capital gains tax
- Total estimated tax: ~$14,000
- Net after-tax value: ~$36,000
If Sarah holds the shares for 2 years and the stock rises to $150, she’ll owe **long-term capital gains tax** on the $25,000 profit—at a lower rate than short-term gains. Our RSU long term capital gains tax calculator helps her compare both scenarios.
Frequently Asked Questions (FAQs)
1. When are RSUs taxed?
RSUs are taxed as ordinary income on the vesting date. The fair market value of the shares on that day is added to your annual income and taxed at your regular rate. If you later sell the shares, any profit above the vesting price is taxed as capital gains.
2. What is the long-term capital gains tax rate for RSUs?
For foreign-listed shares, the long-term holding period is 24 months. If you hold the shares for more than 24 months after vesting, the gain is taxed at 12.5% (without indexation). For Indian-listed shares, the threshold is 12 months.
3. What is the “withholding gap” with RSUs?
Many employers withhold only 22% for federal taxes on RSU vesting. If you’re in a higher tax bracket (e.g., 32% or 35%), you’ll owe the difference when you file your return. Our calculator shows you this gap so you can make estimated tax payments.
4. Do I pay tax on RSUs if I don’t sell the shares?
Yes. You owe ordinary income tax on the vesting value whether you sell the shares or not. The tax is due in the year the shares vest.
5. How is the cost basis for RSUs determined?
Your cost basis is the fair market value on the vesting date. This is the amount already taxed as ordinary income. When you sell, you only pay capital gains tax on the difference between the sale price and this cost basis.
6. Is the RSU Tax Calculator free?
Yes! Our RSU tax calculator is completely free to use. No sign-up, no payment required.
