What Is a Carve Out Plan for Executive Benefits?

A carve out plan for executive benefits is an employer-sponsored, non-qualified arrangement that provides retirement or deferred compensation to a small group of highly paid employees outside the federal limits that apply to a 401(k) or other qualified plan. It exists because qualified plans cap what an executive can accumulate, and carve out plans fill the gap through a contractual promise to pay additional compensation later.

In 2026, qualified plans can only count the first $360,000 of an employee’s pay, and total annual additions to any one account cannot exceed $72,000. Elective deferrals top out at $24,500, or $32,500 with the age-50 catch-up.¹ An executive earning several times the compensation cap hits a ceiling the qualified plan cannot raise.

Why the Qualified Plan Cannot Do the Job

Two sets of rules keep 401(k)s from serving senior executives well. The first is the numeric caps above.² The second is non-discrimination testing. The ADP and ACP tests compare how much highly compensated employees defer against the rate for everyone else, and the HCE average is not allowed to run too far ahead.³ When the plan fails testing, the employer refunds contributions to the HCEs, cutting the benefit further. An employee is treated as highly compensated for 2026 testing if they earned more than $160,000 in the prior year. Federal law requires that contributions or benefits under a qualified plan not discriminate in favor of HCEs.⁴

No amount of clever plan design gets around this. To deliver a competitive retirement package to senior leadership, the employer has to step outside the qualified framework. That is what a carve out plan does.

The Forms a Carve Out Plan Can Take

Three structures cover most of the market. What they share is the basic mechanic: the employer contractually promises additional compensation payable in the future, and the executive accepts deferred receipt in exchange for tax timing that favors them.

Non-Qualified Deferred Compensation Plan

An NQDC plan lets the executive elect to defer salary, bonus, or other current compensation to a future payout date. The employer records the obligation as a balance-sheet liability. It does not segregate the money in a protected account the way a 401(k) does. Vesting schedules, notional investment benchmarks used to credit earnings, and payout triggers are all designed to fit the employer’s retention goals.

Supplemental Executive Retirement Plan

A SERP looks more like a pension. Rather than tracking an account balance, it promises a specific income stream calculated from a formula, usually built on final average salary and years of service. The point is to bring the executive’s overall retirement income to a target replacement ratio despite the qualified plan caps. The executive does not make deferral elections; the employer carries the investment risk and the obligation to deliver.

Excess Benefit Plan

An excess benefit plan is the narrowest form. It exists only to restore benefits the executive would have earned from the qualified plan if the Section 415 annual additions limit did not apply.⁵ Run the qualified formula as if the cap were not there, subtract what the qualified plan actually pays, and the excess benefit plan covers the difference. That narrow scope earns it lighter ERISA treatment.

All three are, at bottom, unsecured promises. The executive is relying on the employer’s future solvency to collect. The differences are about how the benefit is calculated and who bears the investment risk.

How the Tax Deferral Actually Works

The tax advantage depends on deferring income recognition until the money is paid. Two doctrines threaten that. Under constructive receipt, income is taxable once it is credited or made available without substantial restriction.⁶ Under Section 83, property transferred for services is taxed once it is no longer subject to a substantial risk of forfeiture.⁷ Section 409A is the statute that tells the plan how to avoid tripping either wire.

When the Deferral Election Has to Be Made

The election to defer must be made no later than the end of the calendar year before the year the services are performed. Waiting until December to defer a bonus once the number is known is not allowed. For a newly eligible participant, the plan can permit an election within 30 days of first becoming eligible, but only for services performed after the election.⁸ For performance-based compensation tied to a service period of at least 12 months, the deadline extends to no later than six months before the performance period ends.

When the Money Can Be Paid Out

Section 409A restricts distributions to six events:⁸

Separation from service, whether by retirement, resignation, or termination
A fixed date or payment schedule chosen at the time of deferral
Death
Disability
A change in ownership or effective control of the employer
An unforeseeable emergency: a severe financial hardship beyond the participant’s control

Once a distribution trigger is locked in, changing it requires a formal re-deferral election that pushes payment at least five years further out. The plan cannot pay early because the executive wants the money sooner.

What Happens If the Plan Fails 409A

If the plan fails Section 409A in its terms or in operation, the consequences fall on the employee. All compensation deferred under the plan for the current year and every prior year becomes immediately taxable. On top of ordinary income tax, the employee owes an additional 20% penalty tax on the entire amount, plus a premium interest charge accruing from the year the compensation should have been included.⁸ On $2 million of deferred compensation, a documentation error can produce a tax bill above $1 million in a single year.

The employer’s tax treatment mirrors the employee’s on a different clock. The company gets no deduction as the compensation accrues. The deduction arrives in the year the benefit is actually paid and included in the employee’s income.

When FICA Comes Due

Income tax and employment tax do not travel together here. Even though the executive will not owe income tax on the deferred amount until it is paid out, FICA taxes for Social Security and Medicare are due much earlier under a special timing rule.⁹

Deferred amounts are treated as wages for FICA purposes at the later of two dates: when the services that earn the compensation are performed, or when the compensation is no longer subject to a substantial risk of forfeiture.¹⁰ Fully vested deferrals hit FICA in the year earned. Compensation with a three-year cliff hits FICA when vesting is satisfied.

There is an upside. Because FICA is paid on the front end, the payout years later is not subject to FICA again.⁹ If the executive’s other wages already exceed the Social Security wage base ($184,500 in 2026), the deferred amount may escape the 6.2% Social Security tax entirely and face only the 1.45% Medicare tax plus the 0.9% additional Medicare tax on earnings above $200,000.¹¹

How the Employer Sets Money Aside

To preserve tax deferral, the plan has to remain “unfunded.” That does not mean the employer ignores the promise. It means the assets earmarked for the plan stay on the company’s books and remain reachable by general creditors if the company becomes insolvent. The executive is an unsecured creditor with respect to the promised benefit.

Rabbi Trusts

The common answer is a rabbi trust: an irrevocable trust the employer sets up to hold assets earmarked for the plan. The IRS published model trust language in Revenue Procedure 92-64, and the critical provision is that the trust assets must be “subject to the claims of the Company’s general creditors under federal and state law in the event of Insolvency.”¹² The trust protects the executive from a change of heart by future management, because the assets cannot be pulled back for other corporate purposes while the company is solvent. If the company enters bankruptcy, though, those assets join the general creditor pool. Because that creditor exposure remains, funding the rabbi trust does not trigger current income tax for the executive.

Corporate-Owned Life Insurance

Many rabbi trusts are funded with corporate-owned life insurance on the lives of the plan participants. Cash value inside the policies grows tax-deferred, and the death benefit is generally received tax-free by the employer. When the executive retires and begins drawing benefits, the employer accesses policy cash value through withdrawals or loans to make payments. If the executive dies before retirement, the death benefit helps cover the plan obligation to survivors.

Secular Trusts

A secular trust takes the opposite approach: assets are placed irrevocably beyond the reach of the employer’s creditors for the employee’s exclusive benefit. Security is much stronger, but the entire funded amount is taxable to the employee in the year it enters the trust.⁷ That is why secular trusts are rarely used for carve out plans.

ERISA and the Top-Hat Exemption

Most carve out plans qualify for the “top-hat” exemption under ERISA. It covers unfunded plans maintained primarily for a select group of management or highly compensated employees. A plan with top-hat status is exempt from ERISA’s participation, vesting, funding, and fiduciary rules, which makes administration far lighter than a qualified plan. The one obligation that remains is a brief top-hat statement filed electronically with the Department of Labor.¹³ Excess benefit plans get even lighter treatment, because they exist only to restore benefits above the Section 415 cap they are exempt from virtually all of ERISA, top-hat filing included.⁵

The Risk the Executive Carries

Carve out plans deliver real value, but the executive’s side of the deal carries a risk qualified plans do not. The money is not protected if the employer goes under. A 401(k) balance sits in a trust separate from the company; a bankruptcy leaves it untouched. A carve out balance, even one held in a rabbi trust, is an unsecured claim against the company’s estate. In bankruptcy, the executive stands alongside trade creditors and bondholders.

This is not theoretical. When large employers have failed, executives with big NQDC balances have recovered pennies on the dollar or nothing at all. Anyone considering a carve out plan should weigh the employer’s financial stability and whether the deferred compensation stacks on top of other concentrated exposures to the same company, such as salary and stock options.

The compliance risk lands on the executive too. The employer designs and runs the plan, but if the document has a drafting error or a distribution goes outside the permitted triggers, the 20% penalty tax and premium interest under Section 409A hit the executive’s personal return. Having independent counsel read the plan document before signing on is a reasonable precaution, and one most executives skip.
