What Is Deferred Pay? How It Works, Taxes, and 409A Rules

Deferred pay is compensation you earn now but agree to receive later, usually after you retire or leave your employer. It comes in two very different forms: qualified plans like 401(k)s and 403(b)s, which carry federal legal protections and strict contribution caps, and nonqualified plans governed by Section 409A of the Internal Revenue Code, which allow larger deferrals but leave the money exposed to your employer’s creditors. Which type you have determines how much you can put in, when you can take it out, and how safe it is.

How Deferred Pay Works

The mechanics are simple. You and your employer agree that a portion of what you earn will be paid at a later date rather than in your regular paycheck. That agreement is what postpones the tax bill, but only if it holds up under a tax rule called constructive receipt. Under federal regulations, income is treated as received the moment it’s credited to your account or made available to you without substantial restrictions, whether or not you actually take it.¹ A valid deferral has to put real restrictions on the money. You can’t reserve the right to change your mind and pull it out early.

Because the funds stay with your employer until the payout date, deferring pay creates something close to a debtor-creditor relationship. Your employer owes you money, and a contract sets the terms. Whether those dollars are protected from your employer’s own creditors is the single most important thing to understand, and the answer depends entirely on the plan type.

Qualified Plans: 401(k)s, 403(b)s, and Similar Accounts

Qualified plans are the retirement accounts most workers know: 401(k) plans in the private sector, 403(b) plans at nonprofits and public schools, and governmental 457 plans.² They meet the standards of the Employee Retirement Income Security Act (ERISA), the federal law that governs private-industry retirement plans.³

Two features set qualified plans apart. They must follow nondiscrimination rules, so an employer can’t limit participation to top executives while excluding regular staff. And plan assets must sit in a trust separate from the employer’s business accounts. If your employer is sued or files for bankruptcy, the creditors cannot reach the retirement plan trust.⁴ The tradeoff for that protection is a firm ceiling on how much you can defer.

2026 Contribution Limits

For 2026, the maximum you can defer into a 401(k), 403(b), governmental 457, or the federal Thrift Savings Plan is $24,500, up from $23,500 in 2025. Workers 50 and older can add $8,000 in catch-up contributions, for a personal ceiling of $32,500.⁵

A SECURE 2.0 Act provision gives workers aged 60 through 63 a bigger catch-up. If you’re in that age band during 2026, your catch-up jumps to $11,250, allowing total deferrals up to $35,750.⁵

Separate from your own deferrals, Section 415(c) caps the combined annual additions from you and your employer at $72,000 for 2026 (up from $70,000). Section 401(a)(17) caps the salary that can be factored into plan calculations at $360,000.⁶ These caps are the reason nonqualified plans exist. Executives who bump up against them need somewhere else to defer.

Nonqualified Plans and Section 409A

Nonqualified deferred compensation plans sit outside the ERISA framework and are governed primarily by Section 409A of the Internal Revenue Code.⁷ Employers offer them to executives and highly compensated employees who have maxed out their qualified plans. There is no statutory limit on how much salary or bonus you can defer.

The catch is asset protection, or the lack of it. Nonqualified plan money typically remains in the employer’s general accounts, or sits in what’s called a rabbi trust. A rabbi trust holds the money separately in some sense, but the assets remain the employer’s property and are reachable by the employer’s creditors in bankruptcy.⁸ If the funds were actually shielded, the IRS would treat the arrangement as funded and tax it right away. The deferral only works because you bear real credit risk.

People often underestimate what that risk means in practice. If your employer collapses, your claim for deferred compensation stands with the other unsecured creditors. You might recover a fraction of what you deferred, or nothing at all. That is the price of being able to defer amounts a 401(k) can’t hold.

Election Timing

Section 409A is strict about when you decide to defer. As a general rule, the election must be made before the start of the tax year in which you’ll perform the services. To defer any 2027 salary, you have to lock in the election by December 31, 2026. There’s one exception: newly eligible participants have 30 days from their eligibility date to elect deferrals on compensation earned after the election.⁹ Miss the deadline and you can’t defer for that year. The IRS doesn’t grant extensions, and a late election can trigger the full 409A penalty regime.

How Deferred Pay Is Taxed

The core tax deal is the same for both plan types: you don’t pay federal income tax when the compensation is earned, and you do pay it as ordinary income in the year you actually receive the distribution. The rate is whatever bracket applies to you at that point. Long-term capital gains rates do not apply, even if the account grew through investments over decades.

FICA Runs on a Different Clock

Social Security and Medicare taxes don’t wait for the payout. For a nonqualified plan, FICA is owed at the later of two moments: when you perform the services, or when the compensation is no longer subject to a substantial risk of forfeiture (in other words, when it vests).¹⁰ Payroll taxes are collected years, sometimes decades, before you see the money.

For a qualified plan, FICA applies to your elective deferrals in the year you earn them, before they’re diverted into the plan. Your W-2 will show your full salary for Social Security and Medicare purposes even though part of it went into the 401(k).

What Shows Up on Your W-2

Nonqualified plan activity appears in Box 12 of your W-2. Deferrals during the year are reported under Code Y. Amounts actually received from a 409A plan appear under Code Z and are included in your taxable wages in Box 1. If Code Z is on your W-2, the IRS expects the corresponding tax on your Form 1040.

When You Can Take the Money Out

Deferred compensation is not available on demand. The permitted triggers depend on the plan.

Qualified Plan Distributions

Elective deferrals in a 401(k) can be distributed when you separate from your employer, become disabled, die, reach age 59½, or experience a qualifying financial hardship.¹¹ Take money out before age 59½ and you generally owe a 10% additional tax on top of the regular income tax, unless an exception applies.¹²

Commonly used exceptions to the 10% penalty include:

Separation from service during or after the year you turn 55, for distributions from that employer’s plan.
Total and permanent disability.
Death, for the beneficiaries who inherit the account.
A series of substantially equal periodic payments based on your life expectancy.
Unreimbursed medical expenses above 7.5% of your adjusted gross income.
Payments to a former spouse under a qualified domestic relations order.
Up to $22,000 for a federally declared disaster.¹³

Qualified plan balances also can’t stay deferred forever. Required minimum distributions from traditional 401(k) and 403(b) accounts must begin at age 73.¹⁴ The excise tax for missing an RMD is 25% of the shortfall, dropping to 10% if you correct it within two years.¹⁵

Nonqualified Plan Distributions

Section 409A limits nonqualified payouts to six specific triggers: separation from service, disability, death, a change in control of the company, an unforeseeable emergency, or a date fixed in the plan.¹⁶ There is no age-59½ rule and no hardship provision like the one 401(k) plans offer. The plan cannot let you take money out simply because you want it. “Unforeseeable emergency” is defined narrowly and does not include buying a home or paying college tuition. Nonqualified plans are not subject to RMD rules, because 409A already locks the payout timing into the plan document.

Rollovers

When you leave a job, you can typically roll a qualified plan balance into an IRA or into a new employer’s plan and keep the tax deferral going. A direct rollover, where the old plan sends the funds straight to the new account, avoids withholding. If the check is made out to you instead, the plan withholds 20% for federal tax, and you have 60 days to deposit the full amount, including the withheld portion made up from other funds, into an IRA to avoid a taxable distribution.¹⁷

The same penalties apply if the employer shifts plan assets to an offshore trust or restricts assets for participants when the company’s financial condition worsens.⁷ Those rules exist to keep employers from protecting deferred amounts in ways that would sidestep the unfunded requirement 409A depends on.

A missed deferral election, a plan document that lets you accelerate payment, or an impermissible payout can convert a tax-planning arrangement into a large personal tax bill. If you participate in a nonqualified plan, both the plan document and the way the plan is actually administered need to follow 409A precisely.
