What Is an NQDC Plan? How Non-Qualified Deferred Compensation Works
An NQDC plan lets select employees defer salary or bonus, and the income tax on it, until a later payout. Learn how it works, how it is taxed and the risks.
An NQDC plan (non-qualified deferred compensation plan) is an employer arrangement that lets a select group of managers and highly paid employees postpone part of their salary or bonus to a future year, with income tax postponed until the money is paid. The catch is that until it is paid, the money is only an unsecured promise from your employer, and strict timing rules under Internal Revenue Code Section 409A control when you elect and when you get paid.
This guide covers private-employer plans governed by Section 409A, often called executive deferral plans, deferred comp plans or simply 409A plans. It does not cover the state and municipal 457(b) "deferred compensation" plans offered to government workers, which work very differently. If you work for a city, county or state agency, you are probably in a governmental 457(b), and much of what follows will not apply to you.
Your plan document governs the details, so read it alongside this guide and consider talking with a qualified tax or financial professional before you make an election.
What NQDC means and why the plan is "non-qualified"
NQDC stands for non-qualified deferred compensation. The "non-qualified" part is the key to everything else.
A qualified plan, such as a 401(k), meets tax-code requirements for broad employee participation, annual contribution limits and a trust held for employees. In return, the money is protected from the employer's creditors and can be rolled over when you leave.
A non-qualified plan skips those requirements. It can be offered to only some employees, and Section 409A sets no dollar cap on how much you can defer; each plan sets its own percentage limits. The trade-off is that to keep your income tax deferred, the plan must stay unfunded. You hold only the rights of an unsecured general creditor, and any assets set aside remain your employer's general assets (IRS Publication 5528).
How an NQDC plan works, from election to payout
Most elective plans follow the same five steps.
- You elect before you earn the pay. Generally, you must elect to defer pay for a year by the end of the year before. Your 2027 salary election is generally due by December 31, 2026, and it becomes irrevocable when 2027 begins. If you are newly eligible, you usually get 30 days, but only for pay earned after the election (Treas. Reg. §1.409A-2). A performance-based bonus measured over at least 12 months can generally be deferred as late as 6 months before the period ends.
- You choose when and how you will be paid. At the same time, you usually pick a payout trigger and a form, such as a lump sum or annual installments starting at separation from service or on a specified date. Section 409A allows payment only on six events: separation from service, disability, death, a specified time or fixed schedule, a change in control, or an unforeseeable emergency (Treas. Reg. §1.409A-3).
- Your pay is reduced and your account is credited. Social Security and Medicare taxes generally apply now. Income tax does not.
- Your balance tracks investments you choose. Most plans offer a menu of deemed investment options. Your balance rises and falls with them until payout.
- You are paid, and income tax is due then. Payouts are taxed as ordinary wage income in the year you receive them.
| Step | Typical timing | Tax effect |
|---|---|---|
| Election | By Dec. 31 of the year before (30 days if newly eligible) | None |
| Deferral | Each paycheck or bonus date | FICA due now; income tax deferred |
| Growth | Until payout | No tax while the balance grows |
| Payout | The date or event you elected | Ordinary income tax; generally no further FICA |
Changing your payout later is possible but restricted. A change cannot take effect for 12 months, generally must push the first payment back at least 5 years, and for a scheduled date must be made at least 12 months before the first payment. The 409A deferral election rules guide walks through the deadlines.
NQDC plan types and who is eligible
Common plan types
"NQDC" covers several designs. Your employer may offer one or a mix.
- Elective deferral plan. You choose to defer part of your salary, bonus or other pay. This is the plan most employees mean by "deferred comp," and it is the focus of this site.
- Excess benefit or 401(k) restoration plan. The employer restores contributions it could not make to the 401(k) because of qualified-plan limits.
- Supplemental executive retirement plan (SERP). An employer-funded promise of extra retirement benefits, often with its own vesting schedule.
- Deferred bonus or equity deferral. You elect to defer a bonus or the delivery of shares, such as restricted stock units, under special 409A timing rules.
Some elective plans also add employer credits, such as a match on deferred pay. Those credits often vest over time, so check what you forfeit if you leave early.
Who is eligible
Most elective NQDC plans are "top-hat" plans: unfunded plans maintained primarily for a select group of management or highly compensated employees. Because of that limited audience, they are exempt from most ERISA participation, vesting, funding and fiduciary rules (29 CFR §2520.104-23).
In practice, your employer decides who is eligible, usually by job level or pay.
One extra rule applies at public companies. If you are a "specified employee" (broadly, a highly paid officer or owner), payouts triggered by leaving cannot start until 6 months after you separate (26 U.S.C. §409A).
NQDC vs 401(k) and 457(b)
Many participants use both plans, but the differences matter.
| Feature | NQDC (private 409A plan) | 401(k) |
|---|---|---|
| IRS dollar limit on your deferrals | None; plan sets a percentage | $24,500 in 2026, plus catch-up |
| Protected from employer's creditors | No | Yes, held in trust |
| Roll over to an IRA | No | Yes |
| 10% early-withdrawal penalty | No | Yes, before 59½ unless an exception applies |
| Required minimum distributions | No; you set the timing up front | Yes |
| Change payout timing | Only under 409A's 12-month and 5-year rules | Flexible, within plan rules |
Governmental 457(b) plans are a different animal. Their assets must be held in trust for participants, so your employer's creditors cannot reach them (26 U.S.C. §457). A private NQDC plan has no such protection. For a fuller side-by-side, see NQDC vs 401(k).
How NQDC is taxed: the basics
NQDC splits the two big payroll taxes across time.
- Income tax is due at payout. You pay ordinary federal and state income tax in the year the money is paid, at the rates that apply then.
- FICA is due at deferral. Under the special timing rule, vested deferrals count as Social Security and Medicare wages in the year you defer. If your other wages are already above the Social Security wage base ($184,500 in 2026 and $192,300 in 2027), the deferral costs only Medicare tax: 1.45%, plus the 0.9% Additional Medicare Tax on wages above $200,000.
- Growth and payouts are generally FICA-free later. Once a deferral has been taxed for FICA, neither it nor its earnings are taxed for FICA again.
- No 3.8% net investment income tax. Payouts are wages, not investment income (IRS NIIT Q&A).
- No 10% early-withdrawal penalty and no IRS required minimum distributions (26 U.S.C. §72).
As an illustrative, simplified example: $100,000 deferred at a 37% federal marginal rate postpones $37,000 of federal income tax this year. That tax is postponed, not forgiven. Whether you come out ahead depends on your rate when it is paid.
State tax adds a twist. If you take payouts as at least 10 years of substantially equal installments and move, your former state generally cannot tax them (4 U.S.C. §114). See how deferred compensation is taxed and deferred compensation and state taxes for the details.
The main risks of an NQDC plan
The tax deferral comes with real trade-offs.
- Employer credit risk. If your employer goes bankrupt, you stand in line with other unsecured creditors, behind secured creditors. A rabbi trust protects you against a change of heart or a hostile takeover, not insolvency (IRS Notice 2000-56). More in NQDC risks, bankruptcy and rabbi trusts.
- Little liquidity. Before your payout date, you can generally get money out only for an unforeseeable emergency, such as a severe illness or casualty loss. Buying a home or paying tuition generally does not qualify.
- No rollover. Leaving your job usually starts the payout you elected. You cannot move the balance to an IRA. See what happens to deferred compensation when you leave.
- Bracket stacking. A large lump sum on top of other income can push you into a high bracket in the payout year.
- 409A failures. If a plan breaks the rules, vested deferrals can become taxable at once, plus interest and an additional 20% tax.
- No step-up for heirs. Balances paid to beneficiaries are taxed as ordinary income (26 U.S.C. §1014).
How to decide whether to use your plan
The core question is whether postponing income tax beats taking the cash and investing it yourself. A few factors usually decide it.
- Do you expect a lower tax rate when the money is paid, at the federal or state level?
- Have you already used your 401(k), any employer match and an HSA if you have one?
- Can you live without this money until the payout date?
- How confident are you in your employer's long-term finances?
- Will your payout schedule spread income across years or bunch it into one?
The decision framework guide works through each factor, and how much to defer turns the answer into a number. To test it on your own salary, bonus, states and payout schedule, try the free NQDC calculator. It runs the federal and state tax for both paths, year by year.
Frequently asked questions
What does NQDC stand for?
NQDC stands for non-qualified deferred compensation. "Non-qualified" means the plan does not meet the tax-code rules for qualified plans like a 401(k), so it can be limited to select employees and has no IRS dollar cap. It also means your balance is not held in a protected trust.
Is an NQDC plan the same as a 457(b)?
No. A governmental 457(b) for public employees has an annual limit and must hold assets in trust for participants. A private-employer NQDC plan under Section 409A has no IRS dollar limit, and your balance remains subject to your employer's creditors.
Is there a contribution limit on an NQDC plan?
The IRS sets no dollar limit on elective NQDC deferrals. Your plan sets its own limits, often as a percentage of salary and bonus. Check your enrollment materials for the caps that apply to you.
Are NQDC investments real or notional?
Usually notional. You pick from a menu of investment options, and your account is credited with their returns, but you do not own the underlying funds. If your employer sets aside assets, including in a rabbi trust, they remain its general assets.
Can I roll my NQDC balance into an IRA?
No. NQDC payouts are not eligible rollover distributions, so they cannot go to an IRA or a new employer's 401(k). You receive the money on the schedule you elected and pay income tax as it is paid.
