For 409A private company stakeholders, one of the most crucial financial compliance measures is obtaining a fair and defensible 409A valuation. This process determines the Fair Market Value (FMV) of a company’s common stock, and it plays a key role in setting stock option exercise prices for employees. However, many founders, CFOs, and startup boards are often uncertain about how frequently they should update their 409A valuations.

The answer isn’t one-size-fits-all, but it’s governed by regulatory expectations, company milestones, and best practices observed by seasoned 409A valuation firms. In this blog, we’ll explore the importance of 409A updates, when companies are required to update their valuation, and why keeping it current is not just good practice but a strategic move for growing businesses.

What is a 409A Valuation?

A 409A valuation is an independent appraisal of the FMV of a private company’s common stock, typically conducted by third-party 409A valuation firms. The IRS requires this valuation to comply with Section 409A of the Internal Revenue Code, which governs non-qualified deferred compensation. Getting this wrong can lead to severe tax penalties for employees and the company, so it’s critical to stay compliant.

Why 409A Valuations Need to Be Updated

The FMV of a company is dynamic. As your business evolves, whether through new funding rounds, revenue growth, key hires, or strategic pivots, your company’s valuation will change, too. The IRS expects these valuations to reflect the current reality, not a snapshot from years past. Therefore, regular updates are necessary for:

  • Compliance with IRC safe harbor rules
  • Fair equity allocation to employees
  • Supporting audits or due diligence
  • Preparing for fundraising or exit events

409A valuation firms often stress that failing to maintain an up-to-date 409A valuation can signal potential compliance issues during financial audits or IRS examinations.

The General Rule: Every 12 Months

The industry standard for updating a 409A valuation is once every 12 months. This is the maximum time allowed under IRC safe harbor guidelines, assuming no material events have occurred in the meantime.

If your company has not undergone significant changes, an annual valuation is typically sufficient to maintain compliance. But if you want to be safe from penalties and avoid internal disputes over equity, staying within the 12-month window is essential.

When Should You Update Sooner?

While the 12-month rule sets a baseline, private company management must monitor key events that could trigger an earlier update. These material events can significantly impact a company’s fair market value, invalidating a prior 409A valuation. Common triggers include:

1. New Fundraising

Closing a new funding round, especially at a new valuation, often calls for an immediate 409A update. It’s a clear indicator of the company’s changed value and requires input from credible 409A valuation firms.

2. M&A Activity

Whether your company is acquiring another or being acquired, M&A activity alters the financial and operational landscape, necessitating a new valuation.

3. Major Revenue or Profit Changes

Significant growth or decline in revenue, profit, or user base can materially affect valuation. Regular financial milestones should be factored into your valuation process to ensure that the company’s FMV accurately reflects its current state.

4. Product Launch or Pivot

If your company introduces a groundbreaking new product, enters a new market, or shifts business models, your value proposition changes, so should your 409A Valuation.

5. Board-Approved Stock Option Grants

Before issuing new stock options, ensure your current 409A is valid. Most 409A valuation firms recommend a refresh if you’re nearing the 12-month mark or after a material change.

What Happens If You Don’t Update?

Failing to update your 409A valuation at the right time can result in severe consequences:

  • IRS Penalties: Employees may owe income tax, penalties, and interest on stock options.
  • Loss of Safe Harbor Protection: Without a timely valuation, the burden of proof falls on the company to demonstrate fair pricing.
  • Employee Discontent: If employees feel their options were mispriced or unfairly valued, it can hurt morale and retention.
  • Due Diligence Issues: Outdated valuations raise red flags in M&A or funding rounds, slowing deals or even jeopardizing them.

409A private company leaders must view regular valuations not as an obligation but as protection against these risks.

 

Best Practices to Stay Ahead

  • Maintain Clean Financials: Your valuation is only as good as your books. Keep financials accurate and up-to-date.
  • Document Material Events: Track changes that might trigger a valuation update, and consult with your valuation partner if in doubt.
  • Set a Reminder: Create an internal process or calendar alert to revisit your 409A valuation every 12 months.
  • Involve Legal and Finance Early: Loop in legal and finance teams when considering option grants or strategic moves to determine valuation impacts.
  • Audit Your Cap Table: Ensure your cap table is current; any discrepancies could impact valuation accuracy.

  • Industry benchmarks and comparables
