What is a 409A Valuation? Complete Guide for Startups (2025)

If you're raising money or planning to issue stock options to your first employees, you've probably heard someone mention you need a "409A valuation." But what exactly is it, and why does it matter for startups?

Let's break it down in plain English.

The Basics: What Is a 409A Valuation?

A 409A valuation is an independent assessment of what your startup's common stock is worth. Think of it as a formal appraisal, but specifically for the shares you'll be giving to employees through stock options.

The name comes from Section 409A of the IRS tax code, which basically says: if you're going to give employees stock options, the price they pay (called the "exercise price" or "strike price") needs to reflect the actual fair market value of your stock. You can't just make up a number.

Why Do Startups Need a 409A Valuation?

Here's the deal: the IRS doesn't want companies giving employees stock options at artificially low prices, because that would be a sneaky way to avoid taxes. So they require you to use a "reasonable method" to determine what your stock is worth.

Getting an independent 409A valuation creates what's called "safe harbor" protection. Basically, if you have a proper 409A valuation and the IRS comes knocking, they'll presume your valuation was reasonable. Without one? You're on your own to prove your stock price was fair—and if the IRS disagrees, the penalties are brutal.

How brutal? All the deferred compensation for all your employees (from the current year and previous years) could become immediately taxable, plus a 20% penalty on top. That's the kind of thing that can sink a startup and destroy team morale overnight.

How Does the 409A Valuation Process Work?

To get a 409A valuation, you'll hire an independent valuation firm that specializes in startup valuations. They'll ask you for a bunch of information:

• Your cap table and articles of incorporation
• Financial statements (P&L, bank statements, etc.)
• Your pitch deck and business plan
• Details about any recent funding rounds
• Your hiring plans and how many options you expect to grant
• Any "material events" since your last valuation (big product launches, major partnerships, etc.)

For most early-stage companies, the valuation firm will use what's called a "market approach"—they'll look at comparable public companies in your space, check out their stock prices and financial metrics, and use that as a baseline for your 409A valuation.

But here's the key thing: they'll apply a significant discount to arrive at your common stock price. Why? Because your common stock is way less valuable than the preferred stock investors buy. Common stock doesn't have liquidation preferences, voting rights, or any of the other protections that investors negotiate. Plus, it's illiquid—you can't just sell it whenever you want.

When Do You Need to Get One?

You'll need a 409A valuation in a few situations:

First time issuing options: Before you grant your first stock options to employees, you need a valuation in place.

Annual refresh: Even if nothing major happens, you need to update your 409A every 12 months to maintain that safe harbor protection.

After a material event: Raised a new funding round? Dramatically changed your business model? Acquired another company? Time for a new 409A. Any significant event that could impact your company's value means you need a refresh.

Approaching a liquidity event: If you're getting close to an IPO, acquisition, or merger, you'll want an updated valuation.

409A Valuation vs Fundraising Valuation

This is where it gets a bit confusing for first-time founders. You might raise a Series A at a $20 million post-money valuation, but your 409A valuation might come back at $5 million. Wait, what?

Here's why 409A valuations and fundraising valuations are different:

Different stock classes: Investors buy preferred stock with special rights and preferences. Your employees get common stock. The preferred stock is genuinely more valuable, so it costs more per share.

Market vs. methodology: Your fundraising valuation is driven by investor demand—how much someone is willing to pay based on your potential. Your 409A is a formal appraisal using standardized methods and applying discounts for illiquidity and lack of control.

Different purposes: Your fundraising valuation helps you raise capital. Your 409A helps you issue employee options without triggering tax penalties.

The good news? A big fundraise will generally push your 409A valuation up too—just not dollar-for-dollar. The appraisal firm will factor in your recent funding round as evidence of increased value, but they'll still apply those discounts to arrive at the common stock price.

How Much Does a 409A Valuation Cost?

409A valuations typically run anywhere from $2,000 to $11,000+, depending on your startup's stage and complexity. Early-stage startups fall on the lower end, while later-stage companies with complex cap tables pay on the higher end.

Some equity management platforms bundle 409A valuations with their software, which can be more convenient and sometimes more cost-effective than shopping around for separate providers. But you're stuck with their valuation report in that case, and it can take months to speak to someone about correcting it.

Why Investors Care (Even Though It Doesn't Affect Them Directly)

Your 409A valuation doesn't directly impact your investors or your preferred stock price. But investors do care whether you're handling it properly.

If you're sloppy about maintaining current 409A valuations, you're creating risk for the company and potentially exposing your employees to tax penalties. That can trigger an exodus of key talent right when you need them most.

Plus, if you're ever looking to get acquired or go public, serious problems with your 409A history can become a deal-breaker during due diligence. Auditors and bankers will review your option grants, and if they find irregularities, it raises red flags about management competence.

The Bottom Line

Getting a 409A valuation might feel like just another compliance checkbox, but it's actually protecting you, your company, and your team from serious tax consequences.

The key things to remember:

• Get one before you issue your first stock options
• Refresh it every 12 months and after material events
• Use a qualified, independent valuation firm
• Don't be surprised when it comes in lower than your fundraising valuation—that's normal and expected

Once you have a current 409A in place, you can confidently grant options to your team, knowing you've done it the right way. And that's one less thing to worry about as you build your company.
