Employer retirement or deferred-compensation arrangement outside qualified-plan rules, often used for selective supplemental benefits.
A nonqualified retirement plan is an employer retirement or deferred-compensation arrangement outside the tax-qualified retirement-plan framework. It can provide benefits to selected employees, restore benefits constrained under a qualified plan, or defer compensation to future years.
Nonqualified does not mean illegal, unregulated, or tax-free. It means the arrangement does not receive qualified-plan status and must be analyzed under the tax, employment, contract, and reporting rules that apply to its actual design.
| Design | Main purpose | Typical benefit measure |
|---|---|---|
| NQDC plan | Defer salary, bonus, or employer credits | Notional account or scheduled future payment |
| Excess-benefit arrangement | Replace benefits constrained by qualified-plan limits | Difference between a target benefit and qualified-plan benefit |
| SERP | Provide additional employer-funded executive retirement compensation | Formula-based benefit or notional account |
| Individual employment agreement | Promise a benefit to a named employee | Contract-specific lump sum, installments, or retirement income |
One arrangement can fit more than one description. A SERP may be structured as a nonqualified defined-benefit promise, while an excess plan may restore contributions that could not be made to a qualified account.
| Feature | Qualified plan | Nonqualified plan |
|---|---|---|
| Participation | Subject to applicable eligibility and nondiscrimination rules | Can be limited to selected employees, subject to applicable law |
| Benefits or contributions | Subject to qualified-plan limits | Determined by the arrangement and other applicable rules |
| Assets | Generally held under the qualified-plan structure | Often an unsecured employer obligation |
| Portability | May permit rollover or preserve a vested plan benefit | Usually tied to the employer agreement and not rollable like a qualified account |
| Payment timing | Qualified-plan distribution rules | Agreement plus Section 409A or other applicable rules |
| Employer insolvency | Plan assets generally separate from operating assets | Unpaid benefits may be exposed to general-creditor claims |
A qualified retirement plan can still contain investment, fee, funding, and distribution risks. The comparison is about legal structure, not whether one arrangement is universally better.
Assume an employer wants a hypothetical executive to receive total annual retirement benefits of $150,000 under a compensation agreement. The qualified pension formula is expected to provide $100,000 because of plan and tax-law constraints.
The nonqualified supplemental promise is:
$150,000 target - $100,000 qualified benefit = $50,000 per year
The $50,000 may be paid under a SERP after vesting and the required payment event. It is not automatically held in a protected pension fund. If the benefit is an unsecured promise, employer insolvency can affect payment even after the executive has vested.
The example does not establish an actual tax result, legal entitlement, or appropriate compensation level.
Many nonqualified plans are intentionally unfunded for tax and legal reasons. The employer records an obligation and pays from corporate assets when amounts come due. A notional account can track hypothetical investments without transferring those investments to the participant.
An employer may use insurance, a rabbi trust, or other assets to informally finance the obligation. Those assets do not necessarily secure the employee. The IRS rabbi-trust guidance states that model-trust assets remain subject to general-creditor claims if the employer becomes insolvent.
Some U.S. nonqualified plans are designed as top-hat plans for a select group of management or highly compensated employees. The Department of Labor describes eligible top-hat plans as unfunded or insured pension arrangements and provides a top-hat plan statement process.
Top-hat status does not turn the benefit into a protected qualified account. It relates to how specified ERISA provisions and reporting rules apply. Eligibility and legal classification require plan-specific analysis.
Section 409A can apply to salary deferrals, employer credits, supplemental retirement benefits, and other promises of future compensation. The rules generally address initial elections, permissible payment events, subsequent deferrals, and payment acceleration.
The IRS Section 409A examination guide provides the official overview. A nonqualified plan can also implicate payroll-tax, income-tax, constructive-receipt, substantial-risk-of-forfeiture, and other rules. This page therefore avoids assuming that taxation always occurs only at cash payment.
