What Is a Top Hat Plan? Eligibility, ERISA, and 409A Rules

A top hat plan is a nonqualified deferred compensation arrangement that a company offers to a narrow group of senior executives and highly paid employees, letting them defer income well beyond the limits of a 401(k) in exchange for giving up the legal protections that normally come with a retirement plan. The deferred money is an unsecured promise from the employer, not a protected account balance. These plans sit in an unusual regulatory space: they are technically covered by federal pension law, but exempt from almost all of its substantive requirements, on the premise that the executives involved can negotiate for themselves.

Who Can Be in One

Federal law restricts a top hat plan to an “unfunded” plan “maintained by an employer primarily for the purpose of providing deferred compensation for a select group of management or highly compensated employees.”¹ That “select group” phrase carries the whole exemption, and neither Congress nor the Department of Labor has ever pinned it to a specific salary number or percentage.

The DOL’s closest guidance, Advisory Opinion 90-14A, says the exemption was meant for people who, “by virtue of their position or compensation level, have the ability to affect or substantially influence, through negotiation or otherwise, the design and operation of their deferred compensation plan.”² Courts look at both the number of participants and whether those participants are genuinely senior. One influential decision upheld plans covering no more than 8.7% of the workforce where participants earned roughly five times the average employee salary.

Stretching participation too wide puts the exemption at risk. If the DOL or a participant successfully challenges the plan’s scope, the employer carries the burden of proving the group was select, and losing that argument means the plan has to comply with the full weight of ERISA retroactively.

What the Executive Actually Owns

A top hat plan has to stay “unfunded” to keep its special status, which means the deferred compensation is nothing more than a contractual promise. If you participate, you stand in line with every other general creditor of the company. In a bankruptcy, your deferred balance goes into the same pool that unsecured bondholders and vendors are fighting over.

Most employers soften this with what’s called a rabbi trust, named for the IRS ruling that first approved the structure for a rabbi’s deferred compensation. The company puts assets into an irrevocable trust managed by a third-party trustee. Those assets are earmarked for the deferred benefits, and the employer can’t claw them back for ordinary business use.

The one condition that keeps a rabbi trust from being treated as “funded” is also what limits its protection. Under the IRS model trust language in Revenue Procedure 92-64, the trust must provide that if the employer becomes insolvent or files bankruptcy, the trustee stops paying benefits and holds the assets for general creditors. The trust document must say that participants “shall have no preferred claim on, or any beneficial ownership interest in, any assets of the Trust” and that their rights are “mere unsecured contractual rights.”

If the assets were actually shielded from creditors, the executive would be treated as having received the compensation immediately, which destroys both the tax deferral and the ERISA exemption. Section 409A reinforces this by treating any assets placed in an offshore trust, or any trust that restricts creditor access tied to a decline in the employer’s financial health, as a taxable transfer subject to income inclusion plus a 20% additional tax and interest.³

Secular Trusts

Some executives want real asset protection and are willing to pay for it through a secular trust. Unlike a rabbi trust, a secular trust’s assets are beyond the reach of the employer’s creditors. The price is immediate taxation: the employer’s contributions and the trust’s earnings are taxed to the executive in the year they’re contributed or earned. The employer gets a current deduction when the executive is taxed, and later distributions of already-taxed amounts come out tax-free. A secular trust eliminates bankruptcy risk, but it also eliminates the deferral that makes a top hat plan attractive in the first place, so it is rarely the default.

How ERISA’s Exemptions Shape the Deal

ERISA normally imposes four layers of protection on retirement plans: participation and vesting rules, minimum funding standards, fiduciary responsibility, and reporting and disclosure. A top hat plan is exempt from three of them, and the fourth is reduced to a single filing.

Because the vesting rules don’t apply, the plan can impose whatever forfeiture conditions the parties agree to, including full forfeiture if the executive leaves before a set date or breaches a non-compete.¹ Because the funding rules don’t apply, no dedicated assets have to be set aside.⁴ And because the fiduciary rules don’t apply, the company managing the deferred compensation isn’t held to the “prudent person” standard that would govern a 401(k).

The practical consequence shows up in disputes. If the employer denies a benefit claim, the executive can still sue under ERISA, but courts often defer to the plan administrator’s reasonable, good-faith decision, and the plan document itself can hand the administrator wide discretion. If you’re negotiating participation, read the claims and review provisions carefully. The usual ERISA safeguards won’t be there if things go wrong.

Income Tax Treatment

The core appeal is simple. An executive pays no income tax on deferred amounts until those amounts are actually paid out, which may be years or decades later. For someone in a high bracket during peak earning years who expects a lower bracket in retirement, the deferral can mean real savings. The 2026 elective deferral limit for a standard 401(k) is $24,500.⁵ A top hat plan has no statutory ceiling, which is why it is the primary vehicle for executives whose compensation runs far past qualified plan limits.

On the employer side, the deduction mirrors the executive’s income. The company cannot deduct deferred compensation until the year the executive actually receives it and includes it in gross income.⁶ When a rabbi trust is involved, the employer also owes tax on the trust’s investment earnings each year, because those assets are still treated as belonging to the company for tax purposes.

Section 409A

Internal Revenue Code Section 409A governs the timing of deferral elections and distributions for every nonqualified deferred compensation plan, top hat plans included.³ The rules are rigid. Deferral elections generally have to be made before the start of the year in which the compensation is earned. Once a distribution schedule is set, changes are limited and typically require an additional five-year delay.

Failure falls on the executive, not the employer. If a plan violates 409A, all deferred amounts become immediately taxable, plus a 20% additional tax on the includible amount, plus interest at the IRS underpayment rate plus one percentage point, running back to the year the compensation was first deferred or vested.³ On a large balance, the combined cost can wipe out several times the original tax benefit.

FICA Timing

Employment tax works differently from income tax and catches many executives off guard. Under a special timing rule, Social Security and Medicare taxes are owed at the later of when the executive performs the services or when the deferred amount is no longer subject to a substantial risk of forfeiture.⁷ FICA hits at vesting, not at payout.

For most top hat participants, the Social Security portion (6.2% on earnings up to $184,500 in 2026) will already be maxed out through regular salary.⁸ Medicare has no wage cap. The 1.45% base rate applies to all covered wages, and an additional 0.9% Medicare surtax applies above $200,000 for single filers and $250,000 for joint filers. Deferred amounts almost always cross those thresholds, so the combined 2.35% Medicare rate will apply at vesting. Once FICA has been paid at that point, the deferred amount and the investment income it generates aren’t subject to FICA again when distributed.⁷

When Benefits Can Be Paid

Section 409A limits distributions to six triggering events. Benefits can be paid only on:

Separation from service, whether by resignation, termination, or retirement.
Disability as defined under the plan, consistent with 409A standards.
Death, with benefits passing to a designated beneficiary or the estate.
A specified time or fixed schedule set in advance at the time of the deferral election.
Change in control of the corporation or a sale of a substantial portion of its assets.
Unforeseeable emergency, meaning a severe financial hardship from events beyond the executive’s control, such as an illness or casualty loss.

No other event qualifies.⁹ The plan cannot allow early withdrawals, hardship distributions outside the narrow emergency category, or lump-sum cashouts at the executive’s convenience. A payment outside these events triggers the full 409A penalty.

There is one additional wrinkle for public companies. If the employer is publicly traded and the departing executive is a “specified employee” (generally one of the 50 highest-paid officers), any distribution triggered by separation from service has to be delayed at least six months from the separation date, or until death if earlier.¹⁰ Plan for the cash-flow gap if you expect to rely on deferred compensation right after leaving.

The One Filing the Employer Owes

To claim the ERISA exemptions, the employer has to file a one-time statement with the Department of Labor. The filing is submitted electronically within 120 days after the plan first becomes subject to ERISA Title I.¹¹ It includes:

The employer’s name and address.
The employer’s Employer Identification Number.
A declaration that the employer maintains one or more plans for a select group of management or highly compensated employees.
The number of plans and the number of employees in each.

One filing covers all top hat plans the employer maintains, and it replaces the ongoing annual reporting ERISA would otherwise demand.¹¹ The DOL does not review or approve the plan; it simply records that it exists. Miss the window and the plan can fall into full ERISA reporting territory, including Form 5500 obligations, unless the employer corrects the lapse through the DOL’s Delinquent Filer Voluntary Compliance Program, which carries a flat $750 penalty for top hat plans.¹²
