Reporting a calculation error

If you believe our calculators are producing incorrect results, please include:

The calculator you used
Filing year and status
The key inputs (salary, grant details)
The result you expected and why

We are not a tax advisor

We can explain how our calculators work, but we're not able to provide personalized tax or financial advice. For complex equity situations, consult a CPA who specializes in this area.
