Most executives who participate in non-qualified deferred compensation plans spend more time thinking about how much to defer than about the rules governing when they can get it back. That is a costly oversight. IRC Section 409A governs all non-qualified deferred compensation arrangements and imposes strict rules that, if violated, make the deferred amount immediately taxable, plus a 20% excise tax and interest. The violations that trigger this outcome are frequently made by mistake, not by intent.
Non-qualified deferred compensation plans are common tools used to attract and retain executives, and the dollar amounts involved are often large. Even a single administrative error can unwind years of careful tax planning in one filing season.
What a 409A Violation Actually Costs
Imagine an executive who has deferred $150,000 per year for five years, with a plan balance of roughly $800,000. A corporate transaction occurs, HR processes a distribution early, or the executive requests a change to the distribution schedule a few months before the deadline. None of these feel catastrophic. Each one can be a 409A violation.
A 409A violation means the entire deferred balance becomes taxable in the year of violation, plus a 20% penalty excise tax and interest penalties based on the underpayment rate plus 1%. On an $800,000 balance, ordinary income tax at the top federal rate of 37%, is roughly $296,000 in federal income tax alone. Add the 20% excise tax, which applies to the included amount, and the total federal tax burden approaches $462,000 before state taxes or the premium interest charge.
The Core Rule That Drives Almost Every Violation
Section 409A is built around a simple premise: you must decide when you want your deferred compensation before you earn it, and you generally cannot change that decision. The law allows distributions only upon six specific permissible payment events: death, disability, a change of control, a specified time, separation from service, and an unforeseeable emergency. Any payment that occurs outside those events is a violation.
The tension is between flexibility and compliance. Executives naturally want to adjust their distribution timing as life circumstances change. The law treats that flexibility as a loophole to be closed, not a feature to be offered.
The Four Mistakes That Actually Happen
Most 409A violations are caused by administrative errors, missed deadlines, and well-intentioned decisions made without understanding the rules.
- Early payment during a corporate transaction. Any payment made earlier than the scheduled distribution date violates 409A, including well-intentioned early payments by HR during a corporate transaction. When a company is acquired, payroll teams often process distributions to simplify the transition. Unless the plan specifically qualifies under the change-of-control rules and the transaction meets the definition of a qualifying change of control under 409A, that payment is a violation.
- Missing the December 31 deferral election deadline. A deferral election made after the December 31 deadline, even by one day, violates 409A for amounts tied to that election. First-year elections for new participants have a 30-day window from the date of eligibility, but ongoing elections must be completed by the prior calendar year end without exception.
- Changing a distribution schedule too late. Changing a distribution schedule requires a 12-month advance election and a mandatory 5-year extension of the original payment date. An executive who submits the request 11 months before the scheduled date, one month short of the required window, triggers a violation. The 12-month rule is absolute.
- Offshore funding structures. Funding NQDC obligations in certain offshore trust structures violates 409A automatically, regardless of whether any distribution has occurred or any other rule has been broken.
What Can Actually Be Fixed After the Fact
The IRS offers a correction program. Notice 2010-6 allows plan sponsors to correct certain document failures before the plan is used and some operational failures under specific circumstances. The key distinction is between a documentation error and an operational failure.
Documentation errors, such as including impermissible payment events in plan documents before any payments are made, can be corrected by amending the plan document under IRS correction procedures. If the plan says something wrong but no one has acted on it yet, there is a path to fix it.
Operational failures are different. Many 409A violations cannot be corrected after the fact, particularly payment timing violations. An executive who discovers their plan was administered incorrectly years ago may face back taxes, interest, and the 20% penalty on all deferred amounts during the non-compliant period. The IRS has no policy to negotiate settlements on 409A penalties, which means there is no soft landing once the violation is established.
Three Actions Worth Taking Now
The most common mistake executives make is assuming that because their employer administers the plan, compliance is the employer’s problem. Under 409A, the employee bears the tax and excise penalty. The employer may face its own penalties, but the employee cannot shift the tax burden.
Any executive who has ever changed a distribution election, experienced a corporate transaction, or had distributions paid outside their scheduled window should request a 409A compliance review from their employer’s benefits counsel before their next deferral election. That review costs a fraction of what a violation costs.
If you are approaching the December 31 deadline for a new deferral election, confirm the election is submitted and acknowledged in writing before year-end. A verbal or email confirmation is not sufficient documentation if the question ever comes up in an audit.
Finally, if you are considering requesting a change to your distribution schedule, count the months carefully. The 12-month clock starts from the date the election is received by the plan administrator, not the date you decide to make the change. Twelve months is the floor, and the required 5-year extension to your payment date is non-negotiable.
