FAQ

Questions US 409A Impact Calculator owners ask.

  • 01

    How can I find the minimum strike price for a new grant?

    Use the calculate_minimum_strike capability by providing the current Fair Market Value (FMV) and the valuation date.

  • 02

    What happens if I grant options below the FMV?

    Granting below FMV triggers a 20% federal penalty tax plus interest. You can use estimate_tax_penalty to calculate the projected financial impact.

  • 03

    Does this capability cover ISO and NSO differences?

    Yes. The lookup_exercise_rules capability provides specific exercise windows and tax summaries for both ISO and NSO types.
