409A Deferred Compensation Rules: Election Deadlines, Changes and the 5-Year Rule

Under Section 409A, you generally must elect to defer salary by December 31 of the year before you earn it, and the election becomes irrevocable once that year begins. Changing when or how you are paid later requires a new election at least 12 months before the first scheduled payment that pushes the first payment back at least five years.

These timing rules shape almost every decision in a non-qualified deferred compensation (NQDC) plan. They decide when you must choose, what you can change, and how hard it is to reach your money early. Breaking them can make the plan's deferred amounts taxable at once, plus a 20% additional tax and interest.

This guide explains the rules from an employee's point of view, with the main deadlines, the exceptions for new hires and bonuses, and what you can and cannot change later. One note on terms: a "409A valuation" is an appraisal of a private company's stock used when setting stock option prices. It comes from the same section of the tax code, but it is a different topic and is not covered here.

Why Section 409A exists

Before 409A, deferral relied on older doctrines such as constructive receipt and economic benefit. Section 409A, enacted in the American Jobs Creation Act of 2004 and effective for amounts deferred after December 31, 2004, added three layers of rules on top of those doctrines:

• When you can elect to defer pay
• When the plan can pay you (only on permitted events)
• Limits on speeding up or changing payments once they are set

Your employer writes the plan to comply, and the plan document can be stricter than the law. If you want background on how these plans work in general, start with what an NQDC plan is.

The initial election deadline: the prior-year rule

The general rule is simple. To defer compensation for services performed in a year, you must elect by the close of the preceding tax year. For 2027 salary, that means by December 31, 2026. Once 2027 begins, the election is irrevocable for that year.

Open enrollment for many NQDC plans happens in the fourth quarter, before that deadline. Your employer can set an internal deadline earlier than December 31, so check the date in your enrollment materials rather than assuming you have until year-end.

At the same time, you usually choose how each year's deferral will be paid out: when (at separation, on a specified date, or both) and in what form (a lump sum or installments). That payout choice is hard to change later, so it deserves as much thought as the deferral amount. See lump sum vs installments and how much to defer.

Exceptions for new participants, bonuses and vesting awards

The Treasury regulations add a few exceptions to the prior-year rule.

Newly eligible: the 30-day rule

In the first year you become eligible, you may elect within 30 days after becoming eligible. The election can apply only to pay for services performed after the election. For a bonus with a performance period already under way, it generally covers only a prorated portion. You are not treated as newly eligible if you were already eligible under another plan of the same type that must be aggregated with this one.

Performance-based bonuses: the 6-month rule

For performance-based compensation earned over a period of at least 12 months, you may elect as late as 6 months before the end of the performance period. To use it:

• You must perform services continuously from the later of the start of the period or the date the criteria are set, through the election date.
• The amount must not yet be readily ascertainable when you elect.

For example, a bonus tied to calendar 2027 performance can generally be deferred as late as June 30, 2027, if the plan allows it and the bonus qualifies.

Awards that vest after 12 months or more

If you receive a legally binding right that requires at least 12 more months of service to avoid forfeiture, you may elect within 30 days of receiving it, as long as the election is at least 12 months before the earliest vesting date. This is common for deferrals of restricted stock units or retention bonuses.

Bonuses paid by March 15 are not deferred compensation

Under the short-term deferral rule, an amount paid by the 15th day of the third month after the end of the year it vests is not deferred compensation under 409A. For a calendar-year bonus that vests on December 31, that date is March 15.

Key election deadlines at a glance

Changing your payout later: the 12-month and 5-year rules

You can sometimes delay a payment or change its form after the initial election. The statute sets three conditions for a subsequent deferral election:

1. It cannot take effect until at least 12 months after you make it.
2. It must push the first payment back at least 5 years from the date it would have been paid. This does not apply to payments on death, disability or unforeseeable emergency.
3. For payments at a specified time or on a fixed schedule, you must make it at least 12 months before the first scheduled payment.

Here is an illustrative, simplified example. Suppose a deferral is scheduled to pay as a lump sum on January 15, 2030. To delay it, you would need to elect by January 15, 2029, and the new payment date could be no earlier than January 15, 2035.

Installments add a wrinkle. Whether a plan treats a series of installments as a single payment or as separate payments determines how the 5-year push is measured. Your plan document will say which applies.

You also cannot use a later election to speed a payment up. And because the change takes 12 months to become effective, a change to a separation-triggered payout generally does not help if you leave within that year. See what happens to deferred compensation when you leave.

Getting money out early: anti-acceleration and its exceptions

Section 409A bars plans from accelerating payments except as the regulations allow. Exceptions include:

• Payments under a domestic relations order
• Small cashouts of your entire interest, up to the 401(k) elective deferral limit ($24,500 for 2026)
• Amounts to pay the FICA tax on deferred pay, plus related income tax withholding
• Plan termination under strict conditions

Stopping deferrals mid-year is generally not allowed once the year begins, apart from narrow exceptions such as an unforeseeable emergency.

Unforeseeable emergency means a severe financial hardship from illness or accident affecting you, your spouse, beneficiary or dependent, a casualty loss of property, or similar extraordinary circumstances beyond your control. Buying a home or paying tuition generally does not qualify. The payout is limited to the amount reasonably necessary, including taxes, and is not available to the extent insurance, reasonable liquidation of your assets or stopping deferrals could cover the need.

Plan termination is controlled by the employer, not you. Under a general termination, all similar arrangements must end, no termination payments can be made for 12 months (other than amounts already payable), all payments must be made within 24 months, and the employer cannot adopt a similar plan for 3 years. It also cannot be done close to a downturn in the employer's financial health. Separate rules apply around bankruptcy, dissolution and a change in control.

What happens if a plan breaks the rules

If a plan fails 409A in its written terms or in how it is run, all compensation deferred under it for the year and all earlier years becomes taxable immediately, to the extent vested and not already taxed. The tax is increased by a premium interest amount and an additional 20% of the amount included. The income shows on your W-2 in box 1 and in box 12 with code Z.

That penalty falls on the employee, even though the employer runs the plan. It is one reason to follow the plan's procedures and deadlines exactly.

When you are ready to test whether deferring pays off, the free NQDC calculator compares deferring with taking the cash and investing it, across payout schedules from a lump sum to 15 annual installments. It treats your elections as inputs; it does not check them for 409A compliance. Your plan document governs your deadlines and options, so confirm them with your plan administrator and consult a qualified tax or financial professional before you elect.

Frequently asked questions

When is the deadline to elect deferred compensation for next year's salary?

Under the general 409A rule, you must elect by December 31 of the year before you earn the pay, so 2027 salary elections are due by December 31, 2026. Many plans hold open enrollment in the fourth quarter and may set an earlier internal deadline.

I just became eligible. Do I get 30 days to elect?

Generally yes, in your first year of eligibility. The election must be made within 30 days of becoming eligible and can apply only to pay for services after the election. You are not newly eligible if you already participated in a similar plan of the same employer that must be aggregated.

Can I defer my bonus later in the year?

Possibly. If the bonus is performance-based compensation earned over at least 12 months, the plan may let you elect up to 6 months before the period ends, such as June 30, 2027 for a calendar-2027 bonus. You must have worked continuously through the election date, and the amount cannot yet be readily ascertainable.

Can I change my deferred compensation payout date?

Sometimes. A change must be made at least 12 months before the first scheduled payment, cannot take effect for 12 months, and must push the first payment back at least 5 years. You cannot use a later election to move payments earlier.

Can I stop my deferrals or take money out early?

Generally no once the year begins. Limited exceptions include an unforeseeable emergency, small cashouts, domestic relations orders and plan termination by the employer. Buying a home or paying tuition generally does not count as an unforeseeable emergency.

What is the 409A penalty?

If a plan fails 409A, vested deferred amounts for the current and prior years become taxable immediately, plus a premium interest amount and an additional 20% tax. The amount is reported on your W-2 in box 12 with code Z.
