What every startup founder needs to know about 409A valuations

Share This Post

A 409A valuation involves an assessment conducted by an external, impartial party to determine the fair market worth of a private company’s ordinary shares. Startup founders must comprehend this valuation as it determines the fair market value of their company’s overall common stock.

The importance of 409A valuations stems from its legal backdrop — section 409A of the Internal Revenue Code (IRC) mandates that private companies in the United States accurately assess and document their common stock’s fair market value for tax purposes. This requirement guards against the undervaluation of stock options, ensuring that employees’ stock options are issued at a price that reflects the company’s true worth. As such, mastering the nuances of 409A valuations is indispensable for founders looking to align with regulatory standards, incentivize their teams, and safeguard their startup’s future.

This blog will highlight what every startup founder needs to know about 409A valuation.

Legal Requirements

‘409A’ refers to section 440A of the Internal Revenue Code (IRC). The code requires private companies in the United States to determine and document the fair market value of their common stock for tax purposes.

Fair market value

The valuation within the 409A must determine the fair market value of the company’s common stock on a specific date. This figure signifies the amount a purchaser prepared to buy the company would offer and what a seller prepared to sell would agree to in a transaction conducted without any external pressure to buy or sell. 

Timing for valuation

Timing is pivotal when it comes to 409A valuation for startups. Startups must conduct this valuation when they issue stock options, stock appreciation rights, or other equity compensation to their advisers, consultants, and employees. They must also update the valuation annually or when significant events within the company, such as achieving milestones or fundraising rounds, inadvertently affect the company’s value.

Factors for consideration

Startups must consider certain factors related to 409A valuation requirements. The valuation considers the company’s financial performance and growth prospects, market conditions, intellectual property, industrial compatibles, competitive landscape, and recent fundraising or M&A activity. Evaluating these factors helps determine the valuation efficiently.

Finding a qualified appraiser

Startups need to find a qualified independent appraiser to set the valuation. A skilled independent appraiser with experience valuing startups needs to conduct the valuation. The appraiser must also be able to justify the valuation methodologies and assumptions made by the startup.

Valuation methodology

The valuation process can be conducted in many ways. To determine the fair market value of common stock, startups often rely upon the discounted cash flow method (DCF), guideline public company method, option pricing method (OPM), or guideline company transactions method.

Documentation process

Documentation is crucial in the 409A valuation startup process like any other tax operation. Documentation helps demonstrate compliance with IRS regulations and also helps defend the valuation in case of an IRS audit.

Consequences related to incorrect valuation

Common stock and financial reports are related directly to the tax process conducted by startups. By underestimating the value of common stock, startups can underreport income for employees, eventually leading to tax penalties and interest charges. On the other hand, overvaluing the stock can also have adverse consequences for the startup and its stakeholders, such as potential tax liabilities, complications with future fundraising rounds, and M&A transactions.

Approval from the board of directors

Approval of the valuation process is imminent. The startup’s board of directors must review and approve the 409A valuation to demonstrate that it was conducted honestly and in good faith while complying with all legal requirements.

Regular updates

Since a startup evolves like any other company, its valuation will change occasionally. The startup needs to update the 409A valuation regularly to reflect changes in its financial performance, market conditions, and other relevant factors that can affect its overall functioning within its chosen industry.


To conclude, 409A valuations are integral for startups, allowing them to pay taxes efficiently. Understanding and abiding by the rules and requirements of 409A valuation is paramount so startups can lawfully conduct their business while complying with tax regulations. This process also allows them to manage their equity compensation programs and equips them to function diligently within their chosen industry.
