Why does 409A Valuation matter?
Getting this wrong exposes both the company and its option holders to real tax penalties — the IRS requires options be priced at or above fair market value, and a strike price set too low (or a stale valuation used past its shelf life) can trigger back taxes and penalties for the employees who received the grants, not just the company. It is also the number that determines how attractive an option grant actually looks: the gap between the 409A strike price and the preferred price investors just paid is the entire value proposition of joining as an employee rather than an investor.
What does 409A Valuation look like in practice?
Suppose a company raises a priced round at a preferred-share price of several dollars per share, and shortly after gets a new 409A valuation setting the common stock fair market value — usually lower than preferred, since preferred carries extra rights — at a fraction of that. New option grants are priced at that lower common valuation, which is the discount that makes employee options worthwhile. If the company keeps granting options off a 409A from a year earlier without refreshing it after the round, the strike price no longer reflects fair market value and the grants are non-compliant.
What are the common mistakes with 409A Valuation?
- Continuing to grant options off a stale 409A after a material event (a priced round, a large revenue change) that should have triggered a refresh.
- Treating the 409A valuation as the company's real valuation — it deliberately values common stock below the preferred price investors paid, and conflating the two misleads employees about equity value.
- Skipping the appraisal to save cost, exposing option holders to IRS penalties if grants are later found underpriced.
- Not refreshing the 409A on the standard 12-month cycle even absent a major event, letting it lapse and grants go out unpriced.
