What is a nonqualified deferred compensation plan?
Last updated October 2, 2026
A nonqualified (NQ) plan lets a select group of executives defer compensation outside the qualified plan limits. NQ plans escape most ERISA requirements as unfunded "top hat" plans, but they're governed strictly by tax Code Section 409A, where documentation and election-timing errors are costly.
When qualified plan limits are too small for executive retirement needs, employers layer on nonqualified deferred compensation — a contractual promise to pay compensation later, limited to a select group of management or highly compensated employees (the "top hat" group).
The trade-offs that define NQ plans:
- They must remain unfunded — benefits are an unsecured promise, reachable by company creditors — to stay outside most of ERISA (a one-time top-hat filing with the DOL preserves the exemption).
- Section 409A rigidly controls deferral elections, distribution timing, and changes; violations tax the executive immediately plus a 20% penalty.
Governance still matters: keep the plan document current, respect the top-hat boundary, and administer elections precisely — 409A forgives little.
