Every startup that grants stock options eventually collides with two very different numbers: the price investors pay for preferred stock, and the fair market value of the common stock set by a 409A valuation. Confusing the two is one of the most common—and expensive—mistakes founders and employees make.
A 409A valuation is an independent appraisal of your company’s common stock, used to price option grants so they comply with the tax code. It is almost always lower than the preferred price your investors paid, and that gap is a feature, not an error. Understanding why protects everyone holding options from a punishing tax surprise.
What You’ll Learn
What a 409A Valuation Actually Is
Section 409A of the Internal Revenue Code governs nonqualified deferred compensation, and stock options fall squarely inside it. Under 26 U.S.C. § 409A, options must be granted with an exercise price at or above the common stock’s fair market value on the grant date. A 409A valuation is the independent appraisal that establishes that number.
Get it wrong—price options below fair market value—and the consequences land on the employee. The IRS Nonqualified Deferred Compensation Audit Technique Guide describes immediate taxation of vested options, a 20% additional federal tax, and interest charges. A proper 409A valuation is how you avoid handing your team a tax bomb.
Why Common Stock Is Priced Below Preferred
Investors buy preferred stock with a stack of protections: liquidation preferences, anti-dilution rights, board seats, and dividend priority. Employees hold common stock with none of that. Because preferred sits ahead of common in a sale, common is genuinely worth less—often a fraction of the preferred price.
This is why a $10.00 preferred price can coexist with a $2.50 common fair market value from your 409A valuation. It is the same logic that makes fully diluted ownership a different number than your headline stake. Preferred rights, not investor optimism, drive the discount.
The 409A Valuation Safe Harbor
The tax rules reward companies that get an independent appraisal by creating a safe harbor. When you use a qualified independent appraiser, the IRS presumes your valuation is reasonable, and the burden shifts to the IRS to prove otherwise. Notice 2005-1 and the final regulations lay out the framework; the IRS’s initial 409A guidance is the anchor document.
There are three recognized safe-harbor methods: an independent appraisal, a binding formula, and the illiquid-startup presumption for young companies. For nearly every venture-backed company, the independent appraisal is the practical choice and the one investors expect to see in diligence.
5 Critical Facts About 409A Valuations
Keep these straight and you avoid the errors that trigger audits and tax penalties.
- 1. A 409A valuation prices common stock only. It is not your company’s “valuation” in the fundraising sense.
- 2. The safe harbor shifts the burden of proof. Use a qualified appraiser and the IRS must disprove your number.
- 3. Options must be struck at or above the 409A price. Backdating or lowballing the strike creates deferred-compensation exposure.
- 4. Penalties hit the option holder, not the company. A mispriced grant taxes your employees—bad for morale and retention.
- 5. It is time-sensitive. A 409A valuation is generally valid for 12 months or until a material event.
These grant-pricing decisions sit alongside your broader equity compensation strategy and your option pool planning. Treat them as one system, not three separate chores.
When You Must Refresh the Valuation
You need a fresh 409A valuation at least every 12 months, and sooner if a “material event” changes the picture—a new priced round, a significant acquisition offer, a major pivot, or hitting revenue milestones. Issuing options on a stale valuation is a fast way to lose safe-harbor protection.
Financing events are the usual trigger. If you are closing convertible notes or SAFEs or bringing on new accredited investors, plan the refreshed 409A valuation into the timeline. When the IRS challenges a grant, tax-controversy counsel like Howard Law Group defends the position, and operators scaling toward a raise often coordinate with advisors such as Collateral Base.
Frequently Asked Questions
Is a 409A valuation the same as my company’s valuation?
No. A 409A valuation appraises the fair market value of your common stock for option-pricing purposes. Your fundraising or “post-money” valuation reflects the price of preferred stock, which carries rights common shares lack, so the two numbers are usually far apart.
How often do I need a new 409A valuation?
At least every 12 months, or whenever a material event—such as a new financing round or an acquisition offer—changes the company’s value. Granting options on an outdated valuation can forfeit the safe-harbor presumption of reasonableness.
What happens if options are priced below the 409A value?
The option holder can face immediate income tax on vested options, an additional 20% federal tax, and interest under Section 409A. The penalties fall on the employee, which is why accurate pricing at or above the 409A valuation matters for retention.
Next Steps
A 409A valuation protects your team by setting a defensible common-stock price for option grants—separate from, and lower than, the preferred price investors pay. Use a qualified appraiser, respect the safe harbor, and refresh on time.
