409A Valuation Explained: Requirements, Process, and Cost

Founders and CFOs often ask:

• What exactly is a 409A valuation?
• When is a 409A required?
• How does the 409A process work?
• How much does a 409A valuation cost?
• Why is my 409A lower than my fundraising valuation?

This guide answers all of those questions in one place, clearly and practically, so you can issue equity with confidence and remain IRS-compliant.

What Is a 409A Valuation?

A 409A valuation determines the fair market value (FMV) of a startup's common stock for U.S. tax purposes, under Section 409A of the Internal Revenue Code.

Its primary purpose is to ensure that:

• Employees are not granted stock options below fair market value
• Companies avoid hidden compensation and severe tax penalties
• Equity compensation is issued in a compliant, defensible way

When Is a 409A Valuation Required?

A 409A valuation is required before issuing equity compensation, including:

• Stock options
• RSUs (restricted stock units)
• Other equity-based awards

Common 409A Trigger Events

You typically need a new 409A valuation when:

• You issue your first stock options
• You raise a priced funding round
• There is a material change in the business (revenue, growth, strategy)
• You are involved in M&A discussions
• 12 months have passed since the last 409A

Is a 409A Required If You Raised on a SAFE?

Yes.

This is one of the most searched and most misunderstood questions.

A SAFE (Simple Agreement for Future Equity):

• Is not a valuation
• Does not establish fair market value
• Does not replace a 409A

409A Valuation vs Investor Valuation

Another frequent question:

"Why is my 409A valuation lower than my funding valuation?"

The answer lies in what is being valued.

• Investor valuation prices preferred shares, which include liquidation preferences, downside protection, and control rights
• 409A valuation prices common stock, which sits at the bottom of the capital stack

Because common stock carries more risk, its fair market value is typically lower.

How the 409A Valuation Process Works

While the methodology can be complex, the process itself follows a clear structure. The quality of execution depends heavily on your choice of provider—see our guide on 409A valuation services and providers for what to look for.

Step 1: Company & Financial Review

The valuation provider reviews:

• Financial statements
• Cap table
• Business model
• Revenue and growth metrics
• Funding history

Step 2: Capital Structure Analysis

Preferred shares, liquidation preferences, SAFEs, and options are analyzed to understand how value flows through the capital stack.

Step 3: Valuation Methodology Selection

Common methodologies include:

• Option Pricing Model (OPM)
• Probability-Weighted Expected Return Method (PWERM)
• Hybrid approaches

The appropriate model depends on the company's stage, funding history, and exit visibility.

Step 4: Fair Market Value Determination

The result is a defensible FMV for common stock, supported by valuation analysis and documentation.

Step 5: Safe Harbor Protection

A compliant 409A valuation provides safe harbor protection, meaning the IRS will generally accept the valuation unless it is proven grossly unreasonable.

How Much Does a 409A Valuation Cost?

Typical 409A Cost Ranges

• Early-stage startups: $1,000 – $3,000
• Growth-stage startups: $3,000 – $7,000+
• Complex or late-stage companies: higher

Pricing depends on:

• Company stage
• Complexity of the cap table
• Number of financing rounds
• Valuation methodology required

Why Cost Alone Shouldn't Be the Only Factor

A cheap or rushed 409A can:

• Put safe harbor protection at risk
• Lead to incorrect option pricing
• Create issues during audits, fundraising, or acquisitions

How Often Does a 409A Need to Be Updated?

A 409A valuation is generally valid for:

• 12 months, or
• Until a material event occurs (fundraising, acquisition talks, major financial changes)

Whichever comes first. Failing to update a 409A when required can invalidate safe harbor protection.

What Happens If You Don't Get a 409A Valuation?

This is where the risk becomes serious.

Potential consequences include:

• Immediate taxation of option gains
• Additional IRS penalties
• Interest charges
• Employee dissatisfaction and legal exposure

Who Needs a 409A Valuation?

409A valuations apply to:

• U.S. startups
• International startups issuing equity to U.S. taxpayers
• Companies with U.S. parent entities
• Any private company granting equity compensation under U.S. tax rules

Key Takeaways

409A valuations don't have to be confusing, slow, or painful.

When done correctly, they:

• Protect your company
• Protect your employees
• Support healthy growth and fundraising
