Startup 409A Valuation

A 409A valuation is a nonnegotiable part of building a venture-backed startup. Safe harbor with the IRS, fair stock option grants, and avoiding painful tax penalties all depend on getting this valuation right. For founders, knowing what to expect – and how to prepare – streamlines the process, prevents delays, and ensures compliance from day one through Series B and beyond.

What Is a 409A Valuation and Why Does It Matter?

A 409A valuation determines the fair market value (FMV)of a startup’s common stock, setting the “strike price” for employee options and keeping compliance with IRS regulations. You’ll need a current 409A valuation before issuing options, after every new raise, following a material business event (like an acquisition, strategic partnership, or big revenue change), and at least every 12 months.

409A Valuation: What Founders Need to Know Before, During, and After

What to Do Before: The 409A Preparation Checklist

What to Expect During the 409A Process

  • Information gathering. Provide detailed financial and ownership data to the valuation firm promptly.
  • Valuation analysis. The firm chooses the appropriate method (market, income, asset, or backsolve) based on your stage, business model, and recent activity.
  • Review report. Check the report for accuracy; respond quickly to any follow-up questions. Board approval may be required before finalizing.
  • Completion. Receive the final report and retain it with your startup’s core legal and tax records.

After the 409A: Staying Compliant

  • Keep your report accessible. For IRS, audit, and due diligence purposes, you’ll need it handy.
  • Track your expiration. 409A valuations are valid for up to 12 months or until a new material event – schedule regular reviews to avoid lapses.
  • Update your financials. Have you had any major changes to business, funding, or cap table? Be proactive: assess if a new 409A is needed, and notify your provider early.

Put It on Your Calendar

Founders should treat the 409A process as a recurring, strategic function – not a formality. Thoughtful preparation, strong digital records, and staying ahead of your renewal deadline will keep your options compliant, your team incentivized, and your investors happy.
