Section 409A of the Internal Revenue Code regulates nonqualified deferred compensation paid by a "service recipient" to a "service provider" by generally imposing a 20% excise tax when certain design or operational rules contained in the section are violated. Service recipients are generally employers, but those who hire independent contractors are also service recipients. Service providers include executives, general employees, some independent contractors and board members, as well as entities that provide services (an LLC, for example, could be a service provider).
Section 409A was added to the Internal Revenue Code, effective January 1, 2005, under Section 885 of the American Jobs Creation Act of 2004. The effects of Section 409A are far-reaching, because of the exceptionally broad definition of "deferral of compensation." Section 409A was enacted, in part, in response to the practice of Enron executives accelerating the payments under their deferred compensation plans in order to access the money before the company went bankrupt, and also in part in response to a history of perceived tax-timing abuse due to limited enforcement of the constructive receipt tax doctrine.
Section 409A generally provides that "non-qualified deferred compensation" must comply with various rules regarding the timing of deferrals and distributions. Under regulations issued by the IRS, Section 409A applies whenever there is a "deferral of compensation," which occurs whenever an employee has a legally binding right during a taxable year to compensation that is or may be payable in a later taxable year. There are various exceptions, excluding from the Section 409A rules compensation that would otherwise fall within this definition, including: qualified plans like the pension and 401(k) plans, and welfare benefits including vacation leave, sick leave, disability pay, or death benefit plan. Other exceptions include those for "short-term deferrals" (i.e. payments made within 2.5 months of the year in which the deferred compensation is no longer subject to a substantial risk of forfeiture), certain and stock appreciation rights and certain separation pay plans.
