Section 409A establishes comprehensive rules governing nonqualified deferred compensation arrangements - plans that allow executives and key employees to defer income from one year to a future year outside of a qualified plan. Compliance with §409A is binary: either the plan document and its operation fully comply, or the deferred amounts are immediately includible in gross income, subject to a 20% excise tax on top of regular income tax, plus interest at the underpayment rate plus 1%. The penalty is severe enough that §409A compliance is treated as one of the highest-priority obligations in executive compensation practice.
Covered arrangements: Any arrangement that provides for the deferral of compensation to a year after the year of vesting. This includes: traditional deferred compensation plans where executives defer salary or bonus; severance arrangements that extend beyond 2.5 months after year-end; certain equity arrangements (stock appreciation rights with below-FMV prices, restricted stock units with certain features); deferred bonus plans; and some employment agreements with payment timing provisions.
Not covered by §409A: Tax-qualified plans (401(k), pension, SEP, SIMPLE); Roth IRA contributions; welfare benefit plans; bona fide vacation and sick leave arrangements; short-term deferrals paid within 2.5 months after year-end (or the end of the service provider's taxable year, if later).
A §409A plan must specify the time and form of payment at the time of the initial deferral election. Payment may only be made upon one of six permissible triggers:
1. Separation from service: The most common trigger. For key employees of publicly traded companies, there is a mandatory six-month delay after separation before payment can begin. A "key employee" is generally one of the 50 highest-paid officers of a public company with compensation over $220,000.
2. Disability: The plan must use the §409A definition of disability, not just the plan's own definition or the employee's ability to perform their specific job.
3. Death.
4. Change of control: Must meet the §409A definition - generally a change in ownership (50%+ acquisition), change in effective control (acquisition of 30%+ in 12 months or turnover of majority of board), or change in ownership of substantially all assets.
5. Unforeseeable emergency: A severe financial hardship from an event beyond the employee's control. Elective distributions for unforeseeable emergencies are limited to the amount necessary to satisfy the emergency. Tuition, foreseeable medical expenses, and buying a home do not qualify.
6. A specified date or fixed schedule: Payment begins on a pre-specified date elected at the time of deferral. The date must be fixed when the deferral election is made.
A §409A failure causes all amounts deferred under the plan (not just the current year's deferral) that are vested but unpaid to be includible in the service provider's gross income in the year of the failure. The service provider also owes a 20% excise tax on the amount included, plus interest computed at the underpayment rate plus 1%. The combination of regular income tax (up to 37%), the 20% excise, and the interest charge can effectively consume 60% or more of the deferred amount.
Document failures (plan terms that do not comply with §409A) and operational failures (operational deviations from a compliant plan document) have separate correction programs under IRS guidance. Document failures identified and corrected before the income inclusion event generally receive more favorable treatment than operational failures discovered after the fact.
