Why was Medicare deducted from my ISO exercise?

On the exercise of ISOs that resulted in W-2 income of $150,000, the Medicare income was over $1 million and Medicare tax was paid on that amount. Why is that?

Hello Dennis,

Because someone made a mistake. There is no Medicare income from the exercise of an ISO. Go tell your payroll department to fix it, issue a corrected W-2 and refund the excess Medicare tax.

Good luck!
