Meaning
A specific provision of the United States tax code governs the timing and structure of nonqualified deferred compensation. Compliance with IRC Section 409A requires that options and other deferred pay be structured to avoid early tax recognition. It applies to stock options granted to employees and contractors when the exercise price is below the fair market value.
This prevents the deferral of income to tax-advantageous periods without meeting strict conditions.
Valuation Requirement
The determination of the fair market value of the underlying common stock must use a reasonable valuation method. Under IRC Section 409A, an independent appraisal provides a safe harbor that shifts the burden of proof to the tax authority. This valuation must be updated at least once every twelve months or whenever a significant corporate event occurs.
Penalty Avoidance
Failure to comply with the rules leads to immediate tax liability on the deferred amounts. When a grant violates IRC Section 409A, the service provider faces a substantial tax penalty and interest charges.
Compensation Structuring
The design of option pools and executive equity agreements must incorporate the timing restrictions of the tax law. Most startups structure their stock option plans to qualify for an exemption from IRC Section 409A by setting the strike price equal to the fair market value on the grant date. This protects the option holders from unexpected tax burdens.
