Your results
Educational estimate only. This tool does not provide legal, tax, investment, or financial advice. Assumptions may not reflect your full situation.
How to use this estimate
RSUs are usually taxed at vest
For many employees, RSUs are treated as ordinary wage income when they vest. Employer withholding may not fully cover the final tax bill.
Coordinate equity with estimated taxes
If your vesting value is large, estimated tax payments or withholding adjustments may help reduce penalties and cash-flow stress.
RSU
A restricted stock unit is company stock promised to you on a vesting schedule. It usually becomes taxable wage income when it vests.
Withholding gap
A withholding gap happens when employer withholding on vesting stock is less than the tax you may actually owe for the year.
Questions before you use the numbers
