Issued Stock Options Without a 409A Valuation: How to Fix in United States Startups

Granting startup stock options without a formal 409A valuation exposes your employees to severe IRS penalties, including an immediate 20% federal excise tax upon vesting. Fortunately, federal tax guidelines provide specific correction windows to remediate mispriced equity before the calendar year closes. This guide explains how U.S. startups can cure 409A valuation defects through retroactive appraisals, option uppricing under IRS Notice 2008-113, and formal board action.

The IRS Section 409A Trap for United States Startups

In the United States, startup equity is strictly governed by Internal Revenue Code (IRC) § 409A and Treasury Regulation § 1.409A-1(b)(5). Under federal law, stock options escape classification as 'nonqualified deferred compensation' only if their exercise price is set at or above the fair market value (FMV) of the underlying common stock on the grant date. A formal 409A valuation performed by an independent appraiser grants the startup an IRS 'safe harbor' presumption under Treas. Reg. § 1.409A-1(b)(5)(iv)(B). Without this valuation, any strike price chosen by founders or the board carries zero legal presumption of validity.

The most unjust reality of § 409A is who bears the financial punishment. If the IRS audits the company and finds that options were issued below fair market value—even due to a good-faith administrative mistake—the tax penalties fall directly on the employees and service providers you intended to reward. The affected optionee faces immediate ordinary income taxation on the spread as options vest (even before exercise or liquidity), an automatic 20% federal punitive excise tax under IRC § 409A(a)(1)(B), premium interest penalties, and state excise taxes (such as an extra 5% in California under Cal. Rev. & Tax Code § 17501). Left uncorrected, this compliance gap will also derail venture financing due diligence or acquisition negotiations.

IRS Correction Avenues: Notice 2008-113 and Option Repricing

The Internal Revenue Service recognizes that early-stage corporate errors happen and provides an administrative remediation framework under IRS Notice 2008-113. If a startup inadvertently issues discounted options (or grants options without appraisal support), the company can cure the defect by 'uppricing' the options—retroactively raising the exercise price to the verifiable grant-date fair market value.

Crucially, Notice 2008-113 enforces strict, unforgiving deadlines based on recipient status. For company insiders—defined as corporate officers, directors, and 10% or greater equity holders—the correction must be completed before the options are exercised and no later than the last day of the calendar year (December 31) in which the grants occurred. For rank-and-file employees and non-insider contractors, Notice 2008-113 § V.E allows the correction to occur until the end of the subsequent taxable year. Successfully executing this operational cure erases the § 409A violation entirely, treating the options as compliant from the grant date.

Remediation Mechanics and Resolving Your Equity Defect

Remediating a valuation gap requires coordination between independent valuation experts, corporate counsel, and your board of directors. First, the startup must commission a retrospective 409A valuation to establish an audit-defensible fair market value as of the specific grant date. If the retrospective appraisal confirms that the original strike price met or exceeded FMV, the board can formally ratify the grants without changing the price, resolving the safe-harbor uncertainty.

If the appraisal reveals the options were discounted, the board must approve formal option amendments or bilateral repricing agreements with optionees to reset the strike price upward. The company must then attach a formal '§ 409A Relief under § IV of Notice 2008-113' disclosure statement to its corporate federal tax return for the year of correction. Because missing these statutory correction windows can permanently lock in massive employee tax liabilities, you should act before year-end deadlines close.

Steps

• Halt all further option grants immediately until a defensible valuation framework is re-established.
• Engage a qualified, independent 409A appraisal firm to perform a retrospective valuation determining the fair market value of common stock on each grant date in question.
• Compare the retrospective FMV against the issued strike prices; if the strike price is at or above FMV, have the board formally ratify the grants with the supporting appraisal in the corporate minutes.
• If options were granted below FMV, initiate an option repricing (uppricing) under IRS Notice 2008-113, ensuring non-exercised options for insiders are amended before December 31 of the grant year.
• Draft and execute bilateral option amendment agreements with affected optionees reflecting the corrected exercise price.
• Attach the mandatory § 409A Notice 2008-113 informational disclosure statement to the company's federal tax return (Form 1120 or 1120-S) for the tax year the correction took place.

Common mistakes

• Assuming 409A penalties hurt the startup entity rather than realizing the 20% excise tax and accelerated tax bill are levied directly against your employees.
• Arbitrarily picking a strike price based on common stock par value (such as $0.0001) instead of commissioning an independent valuation.
• Missing the December 31 calendar-year deadline to correct mispriced grants held by company officers and directors under IRS Notice 2008-113.
• Attempting to backdate board consent minutes or valuation reports, which constitutes tax fraud rather than a legitimate IRS operational self-correction.
• Continuing to issue equity grants after raising a priced round or experiencing a material business change using a pre-round valuation.

Questions people ask

What happens if an employee already exercised an option that lacked a 409A valuation?

Once an option is exercised, self-correction under IRS Notice 2008-113 is generally unavailable. If the exercise price was below the true FMV, the spread was understated for payroll withholding and income reporting, creating employment tax and withholding liabilities for the startup and § 409A penalties for the individual. You must consult a tax attorney immediately to explore specialized voluntary compliance remedies.

Can a retrospective 409A valuation cure the lack of safe harbor?

A retrospective 409A valuation does not automatically confer the statutory safe harbor presumption retroactively, but it provides contemporaneously defensible evidence of actual FMV. If the appraiser's analysis proves the strike price was at or above FMV at grant, the options are deemed compliant with IRC § 409A without requiring an exercise price increase.

Do we have to reprice stock options if employees do not agree?

Because raising an option's strike price decreases its financial value, optionees generally must consent to an amendment. However, optionees almost always agree once they understand that refusing an uppricing leaves them personally liable for a 20% federal excise tax on vesting, plus ordinary income tax on phantom gains they cannot liquidate. Some companies choose to provide a cash bonus or additional unvested shares to offset the higher strike price.
