Section 409A governs nonqualified deferred compensation. While RSUs and ISOs are often outside the core 409A “deferral” problem, NSOs (and certain RSAs) priced below FMV can create 409A income and penalties because the discount behaves like a deferral of compensation.

Penalty Framework (High Level)

IRC 409A can impose:

  • Income inclusion when deferred amounts vest,
  • Additional tax (often cited as 20% on includible amounts),
  • Premium interest on underpayments,

…subject to detailed regulations and correction programs.


  • Ask for 409A report summary at grant (some companies share).
  • Avoid “handshake” exercise prices without documentation.
  • Escalate if your strike price seems inconsistent with board-approved financings.
