409A Valuation

An independent estimate of a private company's share value, required to set exercise prices for employee stock options. Helps companies comply with IRS tax rules. Typically updated annually or after significant events.

Why it matters

If you're a C-corp issuing stock options, a 409A valuation is legally required. Skipping it means your options could be repriced by the IRS, resulting in penalties for both the company and the employees who received them. It's one of those compliance steps that's easy to overlook early on but expensive to fix later.

The stakes go beyond paperwork. Without a valid 409A, employees who exercised options at below-market prices could owe taxes on the full spread immediately — plus a 20% excise tax penalty — regardless of whether they've sold a single share. For a company raising venture capital, grants made without a compliant 409A will surface during due diligence and can delay or derail a financing round.

There is also a strategic dimension. A low 409A valuation means your employees can exercise options cheaply, which is a meaningful part of compensation. Understanding how your 409A is calculated — and what drives it up or down — helps you make better decisions about timing grants and communicating equity value to your team.

How it works

You hire a qualified independent appraiser (or use a platform like Carta that includes it in their subscription). They analyze your company's financials, comparable transactions, and market conditions to arrive at a per-share value for your common stock. This becomes the minimum strike price for new option grants.

Appraisers typically use one or more of three methodologies: the market approach (comparable company transactions), the income approach (discounted future cash flows), and the asset approach (net asset value). For early-stage companies with little revenue, they rely heavily on the market approach, using data from comparable funding rounds and exits.

You need to update the valuation annually or after a material event like a funding round. Cost ranges from $1,000 to $5,000 for early-stage companies, making it one of the more affordable compliance requirements. Once issued, option grants using that valuation are protected by a "safe harbor" — the IRS is presumed to agree with the price unless it can prove fraud or gross error.

Common stock is typically valued at a 25-35% discount to the preferred stock price, reflecting the liquidation preferences and other rights that preferred investors hold. This discount is intentional and beneficial — it keeps strike prices low enough that options remain attractive to employees.

History and origin

Section 409A was added to the Internal Revenue Code in 2004, enacted as part of the American Jobs Creation Act. It was a direct legislative response to the executive compensation abuses exposed during the Enron and WorldCom accounting scandals, where executives had manipulated deferred compensation arrangements to avoid taxes and shield assets from creditors.

Before 409A, private companies had wide latitude in setting option strike prices, and many took advantage of that flexibility to grant deeply discounted options that were effectively current compensation disguised as deferred equity. The 2004 legislation imposed strict rules: nonqualified deferred compensation — including stock options priced below fair market value — would be taxed immediately upon vesting, with an additional 20% excise penalty.

The IRS issued final 409A regulations in 2007, which formalized the independent appraisal requirement and established the "safe harbor" concept for private companies. This created an entirely new industry of valuation firms specializing in startup 409A work. Today, the 409A is a standard fixture in the startup equity lifecycle, typically handled by platforms like Carta, Pulley, or specialist firms like Andersen, KPMG, or dedicated boutique appraisers.

Frequently asked questions

What is a 409A valuation?

A 409A valuation is an independent appraisal of a private company's common stock fair market value, required by the IRS before issuing stock options. Named after Section 409A of the Internal Revenue Code, it sets the minimum strike price for new option grants and protects both the company and employees from tax penalties.

How often do you need a 409A valuation?

A 409A valuation is valid for 12 months, or until a material event occurs — whichever comes first. Material events include closing a priced funding round, a significant change in company financials, an acquisition offer, or any other event that materially changes the company's value. Most startups get a fresh 409A before each new batch of option grants.

How much does a 409A valuation cost?

For early-stage startups, 409A valuations typically cost $1,000 to $5,000 from a qualified independent appraiser. Some cap table management platforms like Carta include 409A valuations in their subscription plans at no additional cost. More complex companies with significant revenue or multiple share classes can expect higher fees.

What happens if you skip a 409A valuation?

Issuing options without a valid 409A valuation — or at a price below the determined fair market value — exposes the company and the option holders to significant IRS penalties under Section 409A. Employees could owe taxes on the spread immediately as income, plus a 20% excise tax and potential interest. The IRS views this as deferred compensation, not equity.

Who can perform a 409A valuation?

The IRS requires the appraisal to be performed by a qualified independent appraiser — someone with relevant experience, credentials (like an ASA or CFA designation), and no material economic interest in the outcome. Some cap table platforms employ in-house appraisers who meet this standard. The company's own accountants or founders cannot perform a compliant 409A.

Is a 409A valuation the same as a company's valuation?

No. A 409A valuation sets the fair market value of common stock specifically. The company's overall valuation (used in funding rounds) reflects the price investors pay for preferred stock, which carries additional rights and protections. Common stock is typically valued at 25-35% of the preferred stock price, which is why option strike prices can be low even when a company is worth tens of millions.

When should a startup get its first 409A valuation?

A startup should get its first 409A valuation before issuing any stock options. If you plan to build an option pool and grant options to early employees, you need a valid 409A in place first. Many companies get their first 409A shortly after incorporating and raising their initial funding, typically as part of setting up their equity compensation plan.
