What is a 409A Valuation?

A 409A valuation is an independent assessment of a private company's fair market value (FMV) of its common stock. Named after Section 409A of the Internal Revenue Code, this valuation is required by the IRS and must be performed by an independent third party at least every 12 months or when a material event occurs (like a new funding round).

Why 409A Valuations Matter for Employees

Understanding 409A valuations is critical because they directly impact:

  • The strike price of your stock options
  • Your potential tax liability
  • The timing of when you might want to exercise options
Key Components of a 409A Valuation

Common vs. Preferred Stock

  • Preferred Stock: Typically held by investors, includes special rights and privileges
  • Common Stock: Usually held by employees and founders, has fewer rights
  • The 409A valuation specifically determines the FMV of common stock, which is typically lower than preferred stock
Valuation Methods

Independent valuers typically use three main approaches:

Market Approach

Income Approach

  • Based on projected future cash flows
  • Example: A company projecting $10M in free cash flow in 5 years might be valued using a discounted cash flow analysis

Asset Approach

  • Considers the company's tangible and intangible assets
  • Less commonly used for startups and technology companies
Real-World Example

Let's look at a hypothetical scenario for a startup called TechCo:

Initial 409A Valuation:

  • Preferred stock price (latest funding round): $10.00/share
  • 409A valuation of common stock: $4.00/share
  • Employee stock option strike price: $4.00/share

Six Months Later (After Significant Growth):

  • New 409A valuation: $6.00/share
  • New employee stock option strike price: $6.00/share

In this example, employees who received options before the new valuation benefit from a lower strike price, highlighting the importance of timing in equity compensation.

Impact on Employee Equity Compensation

Stock Options

  • Options must be granted with a strike price at or above the current 409A valuation
  • Granting options below the 409A valuation can result in immediate tax liability

Example: Initial Grant:

  • 10,000 options
  • Strike price: $4.00 (based on 409A)
  • If exercised when FMV is $20.00
  • Potential gain: ($20.00 - $4.00) × 10,000 = $160,000

RSUs (Restricted Stock Units)

  • The 409A valuation helps determine the fair market value of RSUs for tax purposes
  • RSUs are typically taxed as ordinary income based on the FMV when they vest

Early Exercise

  • Some companies allow early exercise of options before they vest
  • The 409A valuation determines the price for early exercise and potential tax implications
Tax Implications

ISOs (Incentive Stock Options)

  • No ordinary income tax at exercise if exercised at FMV
  • May trigger Alternative Minimum Tax (AMT)
  • Qualify for long-term capital gains if held for:
    • 2 years from grant date
    • 1 year from exercise date

NSOs (Non-Qualified Stock Options)

  • Taxed at exercise on the difference between FMV and strike price
  • Subject to ordinary income tax rates and payroll taxes

Example Tax Calculation: NSO Exercise:

  • 5,000 options
  • Strike price: $4.00
  • FMV at exercise: $15.00
  • Taxable spread: ($15.00 - $4.00) × 5,000 = $55,000
  • Tax due (assuming 35% rate): $19,250
Best Practices for Employees

Monitor Valuations

  • Keep track of 409A updates
  • Understand how new valuations affect your equity

Consider Exercise Timing

  • Early exercise may have tax advantages
  • Balance potential tax benefits against risk

Maintain Documentation

  • Keep records of grant dates, strike prices, and exercises
  • Document FMV at important dates

Seek Professional Advice

  • Consult tax professionals for complex situations
  • Consider financial planning for large equity positions
Common Pitfalls to Avoid
  • Waiting too long to exercise ISOs, missing out on tax advantages
  • Not understanding the AMT implications of ISO exercises
  • Failing to consider the impact of new funding rounds on valuations
  • Exercising options without understanding the tax consequences


409A valuations are a crucial element of equity compensation that directly impacts both the value of your equity and its tax treatment. Understanding how these valuations work and staying informed about updates can help you make better decisions about your equity compensation and avoid costly tax surprises. Remember that while this guide provides a general overview, equity compensation can be complex and may warrant professional tax and financial planning advice for your specific situation.
