The decision belongs to this fall, not to the year you earn the money
Non-qualified deferred compensation plans, usually called 409A plans, show up at director level and above across San Diego's larger tech, biotech and defense employers. Election windows for the following plan year generally run somewhere between September and December.
Here is the rule that explains why the window sits there. IRS Publication 5528 describes the initial deferral election as one that "must generally be made before the calendar year in which the employee provides services for which the compensation is earned." So the election you make this fall governs money you have not started earning yet.
Two consequences fall out of that, and they get treated as one thing when they are not.
First, the deferral percentage is set before you know what the year looks like. A bonus that lands larger than expected, a job change, a house purchase, none of that reopens the election.
Second, and this is the one people miss, the distribution schedule is chosen at the same moment. Not at retirement. You are picking the payout terms for money you will collect in eight or fifteen years, using what you know in November.
Section 409A allows a subsequent deferral election to push a payment date out, but only under its own timing conditions, and it is a narrow door rather than a general do-over. Publication 5528 also lists the permissible payment events, and "I changed my mind" is not among them. Confirm what your specific plan document allows with your benefits team before assuming either flexibility exists.
What you are holding is the employer's promise, not an account
This is the part most readers underweight, and it is the single biggest structural difference between this and the 401(k) sitting next to it.
A qualified plan holds assets in trust for participants. A non-qualified plan generally does not. Publication 5528 is direct about the mechanics: for the deferral to work at all, the money cannot be set aside from the employer's creditors for your exclusive benefit. If it were, you would owe tax on it now.
Many plans use a rabbi trust, which sounds protective and is not, at least not in the way people assume. Publication 5528 notes that a rabbi trust's assets remain part of the employer's general assets and stay subject to the claims of the employer's creditors if the employer becomes insolvent. That is not a defect in the design. That exposure is the price of the tax deferral.
So in an employer bankruptcy, the participant stands as a general unsecured creditor. Not as a plan beneficiary with the segregated-trust protection a 401(k) balance carries.
Keep in mind this is a statement about legal structure, not about any particular company. Every NQDC plan works this way, at a healthy employer and a struggling one alike. The point is not that a default is likely. The point is that the size of the position matters more than it would if the money sat in a trust.
401(k) deferral versus NQDC deferral, side by side
| Dimension | 401(k) deferral | NQDC (409A) deferral |
|---|---|---|
| If the employer files bankruptcy | Plan assets are held in trust for participants and sit outside the employer's general assets. | Unfunded promise. Amounts cannot be set aside from the employer's creditors, and rabbi trust assets remain subject to general creditor claims on insolvency (Pub. 5528, 2024). |
| Annual ceiling | Capped by the Internal Revenue Code limits the IRS resets each year. | No statutory dollar cap. The plan document sets it. 4 U.S.C. Sec. 114(b)(1)(I)(ii) describes these arrangements as providing benefits in excess of the limits under Code sections 401(a)(17), 401(k), 401(m), 402(g), 403(b), 408(k) and 415. |
| When the election locks | Changeable during the year under plan rules. | Initial deferral election generally made before the calendar year the services are performed, and it fixes time and form of payment (Pub. 5528, 2024). |
| On leaving the employer | Rollover to an IRA or another plan is available. | No rollover. The balance pays on the schedule elected years earlier. |
| When tax is paid | Income tax at distribution. FICA at contribution. | Income tax when paid. FICA generally at the later of when services are performed or when the amount is no longer subject to a substantial risk of forfeiture, under the special timing rule (Pub. 5528, 2024). |
| Cost of a compliance failure | Plan-level correction programs, generally at the employer level. | Income inclusion, a 20% additional income tax, and a premium interest tax, all assessed against the employee rather than the employer (Pub. 5528, 2024). |
Section 409A has applied to amounts deferred or vested in taxable years beginning after December 31, 2004 (Pub. 5528, 2024), so none of this is new law. It is simply law that rarely gets explained at the same moment the election form arrives.
Two exposures, one company
Here is where the creditor point stops being abstract.
Someone deferring a meaningful share of pay into an employer's unfunded promise, while also holding a large RSU position in that same employer, has stacked two exposures on the same credit and the same equity story. The deferred comp is not a diversifier sitting alongside the stock. Both depend on the company.
A client of ours illustrates the second half of that pattern without the deferred comp attached. This example provided for illustrative purposes only. Individual situations and outcomes vary. "She works in tech, and a highly appreciated position in her employer's stock has grown to roughly 30% of her total assets. She knows the concentration is real and she wants to redeploy it. What is actually holding her in place is the tax bill on liquidating a large appreciated position, not disagreement about the risk.
That is worth sitting with, because it is the common case. Concentration is rarely a decision anyone made. It is what happens when the thing you were paid in went up, and the exit has a price. We wrote about the mechanics of that in a framework for RSU vesting windows, which is the piece that usually has to be settled before an NQDC election makes any sense at all.
The tangle here is two separate planning topics wearing one label. One, how much company-linked exposure is already on the books. Two, whether the deferral is attractive on its own tax merits. Answering the second without the first is how people end up more concentrated than they intended. Where deferred comp sits relative to equity comp and taxable savings is the larger question our San Diego HENRY strategy page is built around.
Lump sum or installments, decided in November
Two live branches, and the consequences differ on both sides.
Lump sum at separation. Simple, and it drops the entire deferred balance into a single tax year. For someone who deferred to escape a high bracket during their working years, a lump sum can rebuild the exact bracket they were avoiding. It also ends the credit exposure the day it pays.
Installments over a period of years. Spreads the income across brackets, and keeps you as an unsecured creditor of the employer for the length of the payout. You are trading tax smoothing against a longer tail of exposure. That is a genuine tradeoff, not a preference.
For a California earner there is a third variable, and it deserves precision rather than enthusiasm.
Under 4 U.S.C. Sec. 114, enacted in 1996 and applying to amounts received after December 31, 1995, no state may impose income tax on the retirement income of someone who is not a resident or domiciliary of that state. Non-qualified deferred compensation reaches that protection through subsection (b)(1)(I), which covers arrangements described in Code section 3121(v)(2)(C), but only on conditions. The income has to be part of a series of substantially equal periodic payments, made not less frequently than annually, over the life or life expectancy of the recipient, or over a period of not less than 10 years.
Ten years is a floor written into the statute, not a rule of thumb. A lump sum does not meet the periodic-payment test. A five-year installment schedule does not either. There is a separate route at subsection (b)(1)(I)(ii) for payments received after termination under an arrangement maintained solely to provide benefits above the qualified-plan limits, which is what many excess-benefit plans are, and that clause does not carry the ten-year condition. Which route a specific plan falls under is a question for the plan document and a CPA, not an assumption to make from the outside.
None of that determines whether leaving California is a good idea, and residency is decided under California's own rules regardless of what the federal source rule says about the former work state. It is one input. It happens to be an input that gets locked by an election form years before anyone is thinking about where they will live.
The order the money comes out in interacts with everything else that pays out in the same years, which we walked through in the order you tap your accounts in retirement.
What genuinely argues in favor
Plenty, and framing this only as a cautionary piece would leave out the half that makes people say yes.
First, real current-year deferral. Income you do not receive is income you do not report, and for a high earner in a high-tax state that is a live number this year, not a projection.
Second, potential bracket arbitrage. Deferring at a peak-earning marginal rate and collecting in a lower-income year is the whole design. Whether it works depends on where rates and your own income land in a year nobody can see from here, which is a caveat, not a disqualification.
Third, deferral room past the qualified-plan ceiling. That is precisely what these plans exist to do. The statute itself describes them as providing benefits in excess of the Code limits.
Weigh that against an unsecured promise and an irrevocable schedule. Reasonable people land differently on the same facts, and the answer moves with how much of your balance sheet is already tied to the employer.
What to settle before December 31
Ordered, and there is a check before the irreversible step.
One. Pull the plan document and confirm what the distribution options actually are. Not the summary, the document. Lump sum, installments, the available lengths, and whether a separate election applies to each deferral year.
Two. Add up what is already tied to the employer. Vested and unvested RSUs, ESPP shares, options, plus any existing deferred balance. Evaluate the total against everything else you own before adding to it.
Three. Ask your benefits team, in writing, what happens to your balance in a change of control and whether the plan permits any acceleration. Plans differ here more than people expect.
Four. Confirm with your CPA which subsection of 4 U.S.C. Sec. 114 your plan would fall under, if a move out of California is anywhere in your thinking. That answer changes what installment length is worth choosing.
Five, and only after the first four. The election itself is the last step, and it is the one that cannot be undone.
Common questions
Can I change my deferred comp election after the plan year starts?
Generally not. Under Section 409A the initial deferral election specifying the time and form of payment must generally be made before the calendar year in which the services are performed, and it is effectively locked once made. A subsequent deferral election can push a payment date out under narrow timing conditions, but there is no general right to reverse or reduce an election mid-year.
What happens to my deferred compensation if my employer files for bankruptcy?
A non-qualified plan is an unfunded promise from the employer, so the participant is generally a general unsecured creditor rather than a plan beneficiary with the segregated-trust protection a 401(k) balance carries. IRS Publication 5528 notes that rabbi trust assets remain part of the employer's general assets and subject to the claims of the employer's creditors if the employer becomes insolvent. This is how every NQDC plan is structured, not a comment on any particular employer.
Does moving out of California before the money pays out avoid California tax on it?
Only on conditions. Under 4 U.S.C. Sec. 114, no state may tax the retirement income of a non-resident, and non-qualified deferred compensation qualifies if the income is part of a series of substantially equal periodic payments made not less frequently than annually over the life or life expectancy of the recipient, or over a period of not less than 10 years. A lump sum does not meet that test. A separate clause covers payments received after termination under a plan maintained solely to provide benefits above the qualified-plan limits. Which clause applies to a specific plan is a question for the plan document and a CPA.
How is a deferred comp plan actually different from a 401(k)?
Four differences matter most. Creditor protection, because 401(k) assets sit in trust and NQDC balances do not. The contribution ceiling, because a 401(k) is capped by Code limits and an NQDC plan is capped only by the plan document. When the election locks, because a 401(k) deferral can generally be changed during the year and a 409A election cannot. And portability, because a 401(k) can be rolled over on separation and a deferred comp balance pays on the schedule elected years earlier.
What is the penalty if a deferred comp plan fails Section 409A?
The deferred amount becomes includible in gross income, and IRS Publication 5528, revised March 2024, states that amounts included under Section 409A are subject to an additional 20% income tax plus a second tax based on imputed underpayment interest, referred to as the premium interest tax. Both are assessed against the employee rather than the employer.
Where this leaves you
Your benefits portal can tell you the deferral percentages available and the deadline. What it will not do is tell you how much of your balance sheet is already pointed at the same employer, or which installment length is worth choosing given where you expect to live.
Those questions sit alongside equity comp, taxable savings and the qualified plan, which is what our San Diego HENRY strategy page is organized around. If it would help to talk a specific election through before the window closes, a complimentary review is available, and fee is discussed there.
