📊 RSU Tax Calculator
Calculate your tax obligations for restricted stock units
How to Use This Tool
Enter the number of RSUs you're vesting and the current stock price to calculate your gross value. Select your federal and state tax rates from the dropdown menus, or choose 'Custom Rate' to enter specific percentages. Choose whether you plan to sell immediately or hold for long-term capital gains treatment. Click 'Calculate Taxes' to see your estimated tax obligations and net proceeds.
Formula and Logic
The calculator uses the following formulas:
- Gross Value = Number of RSUs × Current Stock Price
- Federal Tax = Gross Value × Federal Tax Rate
- State Tax = Gross Value × State Tax Rate
- Payroll Taxes = Gross Value × 7.65% (Social Security + Medicare)
- Total Tax = Federal Tax + State Tax + Payroll Taxes
- Net Value = Gross Value - Total Tax
- Effective Tax Rate = (Total Tax ÷ Gross Value) × 100
Practical Notes
RSU taxation occurs at vesting, not at grant or exercise. The fair market value at vesting becomes ordinary income subject to federal, state, and payroll taxes. Consider setting aside 30-40% of your RSU value for tax payments. If you hold shares after vesting, future sales may qualify for long-term capital gains rates if held over a year. Keep detailed records of your cost basis for future tax filings. Some employers offer tax withholding services or sell-to-cover programs to help manage the tax burden.
Why This Tool Is Useful
RSUs can represent a significant portion of compensation for tech employees and financial professionals. Understanding the tax implications helps with financial planning and cash flow management. This calculator provides transparency into what portion of your RSU grant will actually be available after taxes. It's especially valuable during financial planning, when budgeting for large vesting events, or when comparing job offers with RSU components.
Frequently Asked Questions
Are RSUs taxed when they vest or when I sell them?
RSUs are taxed at vesting when you receive the actual shares. The fair market value at that moment is treated as ordinary income. If you sell the shares later, any additional gain or loss is treated as capital gains or loss.
Can I reduce my RSU tax burden?
Consider maximizing tax-advantaged accounts like 401(k) or IRA before RSU vesting to reduce your overall taxable income. Some employers offer sell-to-cover programs where shares are automatically sold to pay taxes, reducing your out-of-pocket cost.
What happens if I don't have enough cash to pay RSU taxes?
You'll need to sell some shares to cover the tax bill, which may trigger additional capital gains tax. Plan ahead by setting aside 30-40% of your RSU value for taxes. Some brokers offer margin loans or other financing options for this purpose.
Additional Guidance
Consult with a tax professional for personalized advice, especially if you have complex financial situations or live in a high-tax state. Consider the timing of your RSU sales relative to other income for optimal tax planning. Keep all documentation from your employer regarding RSU grants, vesting schedules, and tax withholdings for accurate tax filing.
