Frequently Asked Questions
How are RSUs taxed when they vest?▾
RSUs are taxed as ordinary income at the fair market value on the vesting date. Federal income tax, state tax, Social Security, and Medicare are all withheld from the vested shares.
What is the default withholding rate for RSUs?▾
Most employers withhold a flat 22% federal tax (37% for amounts over $1M), plus state tax and FICA. Actual tax owed may differ, so this calculator shows the full picture.
Do I owe more taxes on RSUs when I file my return?▾
Often yes. The 22% flat withholding may be less than your actual marginal rate. This calculator shows estimated taxes at your actual bracket so you can plan for any shortfall.
