⚠ Tax year 2024 figures. Estimates only — consult a tax professional.

How to use NSO Tax Calculator

  2. The calculator estimates the ordinary income tax due at exercise (the spread between FMV and strike price).

Limitations

  • This estimates federal ordinary income tax treatment at exercise — it doesn't account for state tax, AMT interactions, or your specific tax bracket beyond the estimate shown. Consult a tax professional before exercising options based on this alone.
