409a Corrections

Section 409A governs how nonqualified deferred compensation must be designed, documented, and paid — and the penalties for getting it wrong fall on the executive, not just the company. Understanding where plans go wrong, and how the IRS correction programs actually work, can mean the difference between a minor fix and a major tax event.

This page covers the correction programs in detail. For the underlying rules, see our complete guide to 409A deferred compensation plans.

Why 409A Exists: The Enron Origin Story

In 2003, the House Ways and Means Committee proposed a bill that effectively “eliminated” the possibility of deferred compensation — all because executives at Enron had “swapped” future compensation for a life insurance benefit placed outside the reach of both individual and company creditors. With approval from a board that did not know the company was failing, they accelerated their payments before the collapse came to light. In response, Congress created IRC 409A, the rules that now govern deferred compensation — and the corrections required when those rules are broken.

Fast forward to today: under IRC 409A, specific rules and guidelines are defined to prevent what occurred in 2003. The law requires a company to define numerous items as part of the deferred compensation plan at the time the plan is established. The plan document outlines the responsibilities of both employer and employee — including when and how compensation is earned and paid (two very different things for tax purposes, depending on the tax structure of the company) — and defines all of the terms of the plan.

That history explains why the correction programs are built the way they are. Congress was reacting to deliberate manipulation of payment timing, so the relief the IRS offers is reserved for mistakes that are genuinely inadvertent and caught promptly. Intentional failures get nothing.

What the Plan Document Must Define

A list of items defined in the plan document or its addendum should include, but is not limited to, the following:

• Plan Date
• Effective Date
• Payment Dates
• Who can defer — Employer: Is it discretionary? Is it a match? Employee: How much can be deferred (Base Salary, Bonus, Performance‑Based Comp?)
• When can you defer
• When you can take a payment
• How you can take a payment — Lump Sum? Equal Payments (3‑5‑10 years)?
• When can it be re‑deferred
• Penalties

This level of detail is precisely why disciplined plan design matters so much — a theme we explore in why NQDCs are indispensable and across both 401(k) Mirror Plan structures.

Two Kinds of Failure, Two Different Programs

This is the distinction that determines everything else, and it is the one most often missed:

• A document failure means the plan is written in a way 409A does not allow — an impermissible payment trigger, a defective definition of separation from service, discretion over timing that the sponsor should not have. The plan is non‑compliant from the day it was signed, whether or not anyone has acted on it. These fall under Notice 2010‑6.
• An operational failure means the document is fine but the administration was not — a payment made early, a deferral election accepted late, the wrong amount credited. These fall under Notice 2008‑113.

The programs have different deadlines, different relief, and different consequences. A plan can have both kinds of failure at once, and each has to be corrected under its own program.

Common Operational Errors

Companies tend to make a number of errors when it comes to Section 409A compliance, including:

• Incorrect calculation of plan deferrals and distributions
• Failure to make deferral or distribution elections in a timely manner
• Failure to comply with Section 409A definitions for specified terms
• Early payment of an amount payable in a later year
• Late payment of an amount payable in an earlier year
• Missing the mandatory six‑month payment delay for a specified employee of a public company
• Allowing a deferral in excess of what the plan permits

In our experience the most common cause is not ignorance of the rules. It is a handoff — a payroll provider changes, an HR director leaves, a controller approves a distribution as a courtesy without realising the plan fixes the date. The rules are administered by people who often have no idea the plan is governed by a tax statute with a 20% penalty attached.

The Penalties Are Severe

Unfortunately, with errors come significant penalties, including:

• Immediate income recognition of the participant’s entire plan balance (the “taxable amount”) with respect to the year of the error
• Potential late payment penalties and interest on the taxable amount
• An additional 20 percent tax and “premium interest tax” on the taxable amount
• Potential late penalties and interest on failure to withhold
• Restating and refiling previous years’ tax forms (e.g., Forms W‑2 and 1099 for companies and Form 1040 for plan participants)

Note that these penalties land primarily on the participant — the executive — which is why careful administration of every deferred compensation arrangement, including those at not‑for‑profits, is so important. Note also that the inclusion is not limited to the amount involved in the error. An uncorrected failure can pull the participant’s entire balance under that plan, and under all similar plans of the same employer, into income.

Correcting an Operational Failure: Notice 2008‑113

Relief under Notice 2008‑113 narrows sharply with time, which is the whole reason an annual review pays for itself.

Same taxable year: the best outcome

If the failure is identified and corrected within the same taxable year in which it occurred, the amount is generally treated as though it had been deferred correctly, or never deferred, as the case requires. There is no 409A income inclusion and no 20% additional tax. If an executive was paid early, they repay it before year end. If a deferral was missed, the plan adjusts the account. An insider whose erroneous amount exceeds the annual elective deferral limit also owes interest at the short‑term applicable federal rate.

The following year: non‑insiders only

Correction in the year immediately after the failure is available only to service providers who are not insiders. The executive repays the amount with AFR‑based interest. The repayment is deductible from adjusted gross income; the interest is not. Anyone who was an insider at any point during the failure year or the following year is excluded from this relief entirely.

Small amounts

Where the erroneous amounts in aggregate do not exceed the annual elective deferral limit for the year, income inclusion is limited to the erroneous amount itself, and the executive owes the 20% additional tax but not the premium interest tax. Relief here requires filing an original or amended return by the end of the second year following the failure.

By the end of the second year

For other failures, repayment is due by the end of the second taxable year following the year of the failure. Income inclusion is again limited to the erroneous amount, with the 20% additional tax and no premium interest tax. Insiders must pay AFR‑based interest on the repayment; non‑insiders need not.

What “insider” means here

An insider is a director or officer of the service recipient, or a person who directly or indirectly beneficially owns more than 10% of any class of equity security. The determination uses the SEC’s Section 16 rules whether or not the company’s securities are registered, and applies by analogy to non‑corporate employers. For most closely held companies, that means the people most likely to be in the plan are also the people with the least relief available — which is exactly why same‑year correction matters so much for an owner‑operator.

What disqualifies you

• The failure must be inadvertent and unintentional. Intentional failures get no relief.
• Relief is unavailable if the service provider’s federal return for the failure year is under examination with respect to the plan.
• The employer must take commercially reasonable steps to avoid recurrence, and must look for substantially similar failures in its other plans. A repeat of a substantially similar failure can disqualify relief.
• Relief is unavailable for any year in which the employer is in a substantial financial downturn, or anything else suggesting a real risk it cannot pay the deferred amounts. The program is not an escape hatch for a company heading toward insolvency.

Correcting a Document Failure: Notice 2010‑6

Document failures work on a completely different logic. The fix is an amendment, and the governing question is whether the payment event has already happened.

What can be corrected

• Ambiguous terms, including undefined payment events and “as soon as reasonably practicable” language. If the plan has actually been operated in compliance with 409A, no amendment may be needed at all.
• Impermissible definitions of separation from service, change in control or disability — correctable by amendment before the event occurs.
• Impermissible payment periods following a permissible event, though a late amendment carries income inclusion.
• Impermissible payment events or schedules, impermissible reimbursement or in‑kind provisions, and impermissible sponsor discretion over timing.
• A missing six‑month delay for specified employees.
• Impermissible initial deferral elections, but only where the election was revoked before the 409A deadline, with the plan corrected by the end of the second tax year after that deadline.

The one‑year rule, and the 50% and 25% inclusions

This is the part that surprises people. Amending the document is not by itself the end of the matter. If the event that would have triggered payment under the pre‑amendment plan does not occur within one year of the correction, there is no income inclusion and the correction is clean. If it does occur within that year, a portion of the deferred amount comes into income:

• 50% of the amount deferred, where a separation from service occurs within one year of the correction.
• 25% of the amount deferred, where a change in control occurs within one year of the correction.
• 50% in several other categories, including a late‑amended payment period or a six‑month‑delay separation occurring within the year.

These inclusions carry the 20% additional tax but not the premium interest tax. The practical consequence is that a company contemplating a sale or a senior departure should fix its documents well before the event, not during it. Correcting a plan the month before a change in control is the most expensive possible timing.

Relief for a plan’s first year

A document failure in a plan’s first year can be corrected by amendment with more generous treatment. The clock runs from when the first legally binding right to the deferred compensation arose, and the deadline is the later of the end of that calendar year or the fifteenth day of the third month after the right arose, taking all aggregated plans into account. For a newly adopted plan, this is a genuine grace period and worth using.

Conditions and limits

As with operational failures, the taxpayer bears the burden of proving eligibility, intentional failures are excluded, and relief closes once the relevant return is under examination on the deferred compensation issue. An employer that corrects one document failure must take commercially reasonable steps to identify and correct substantially similar failures in its other plans.

Reporting the Correction

Corrections are not silent. Where income inclusion applies, the employer reports the amount as Section 409A income on Form W‑2 or Form 1099, using Box 12, Code Z, and the executive includes it and pays the additional tax on an original or amended return. Both parties are generally required to attach an information statement to the relevant return describing the failure and the correction. Same‑year operational corrections have lighter reporting, which is one more argument for catching problems early.

What to Do If You Suspect a Problem

1. Write down the date you discovered it. Relief turns on taxable years, and you may need to show when the clock started.
2. Stop any pending payment. A distribution made while the question is open can convert a document question into an operational failure as well.
3. Determine which kind of failure it is. Document, operational, or both. The answer determines which program applies and what the deadline is.
4. Check the calendar against the tax year, not the date. A failure discovered in December has materially better options than the same failure discovered in January.
5. Identify who is an insider. This changes what relief is available, and in a closely held company it usually applies to the people in the plan.
6. Bring in your attorney and CPA before amending anything. An amendment made in the wrong order, or at the wrong time relative to an anticipated event, can cost more than the original error.
7. Look at the other plans. Both programs require it, and a substantially similar failure elsewhere can disqualify your relief.

Frequently Asked Questions

How long do I have to correct a 409A failure?

It depends on the type. Operational failures have the best relief in the same taxable year, reduced relief in the following year for non‑insiders, and limited relief through the end of the second year after the failure. Document failures are correctable by amendment at any time before the payment event, but an event occurring within a year of the correction triggers partial income inclusion.

Does the company or the executive pay the penalty?

The executive. Income inclusion, the 20% additional tax and the premium interest tax all fall on the participant. The company’s exposure is reporting, withholding and the relationship consequences of having handed a key employee an unexpected tax bill.

Can we just fix it quietly and not report it?

No. Where income inclusion applies, reporting is part of the relief. Correcting without the required reporting and information statements generally forfeits the relief, which leaves you with an uncorrected failure and the full penalty exposed.

What if the IRS finds it first?

Relief under both programs closes once the relevant return is under examination with respect to the plan. These are voluntary correction programs, and the voluntary part is the point.

We are about to sell the company and I think our plan has a document problem. What now?

Move immediately, and before the transaction. A change in control occurring within one year of a document correction brings 25% of the deferred amount into income. The same correction made well in advance of the sale can carry no inclusion at all. This is the single most expensive timing mistake available in this area.

Is a 409A failure ever uncorrectable?

Yes. Intentional failures are excluded, as are failures tied to listed transactions. Certain plan designs sit outside the document program — notably plans where the time or form of payment is linked to another plan. And once the correction windows close, there is no program left; the failure simply stands with its full consequences.
