RSU Tax Gap Calculator
Palm Capital Wealth Management
The RSU Tax Gap Calculator
Estimate the difference between what your company withholds when your RSUs vest and what you may actually owe.
- Most public companies withhold federal tax on vesting RSUs at a flat default rate. If your total income puts you in a higher bracket, no one sends a warning — the shortfall shows up on your return.
- Three inputs, about two minutes. Filing status, estimated income, and the value of RSUs vesting this year.
- No call, no pitch. Just an estimate of your number.

This calculator provides a simplified estimate for illustrative purposes only and is not tax, legal, or investment advice. Estimates use 2026 federal income tax brackets and assume the standard deduction; they exclude state and local taxes, Medicare surtaxes, other withholding, deductions, and credits. Federal withholding on supplemental wages is assumed at 22% (37% on amounts over $1 million). Your actual tax situation will differ. Consult a qualified tax professional regarding your circumstances.
