What Are 409A Permissible Payment Events? The Six Triggers

Section 409A governs deferred compensation: pay you have a right to in one year that is paid in a later one. The law lists six 409A payment events. When the pay is deferred, the plan must say which event triggers payment, and in what form. The date must follow from the event by a fixed rule. Nobody, you or the company, can pick it later.

Some flexibility is allowed. A plan may pay within a set window after the event, if the window stays within one tax year or lasts no more than 90 days. You cannot choose the tax year. A plan may also pay on the earlier or later of two listed events. It may set only one time and form for each event, under the anti-toggle rule.

A payment counts as on time if it is made later in the same tax year as its date. It is also on time by the 15th day of the third month after the date. A payment up to 30 days before its date is not treated as early. Both rules hold only if you have no say over the tax year of the payment.

The first event has its own page on separation from service, and the six-month wait at public companies is covered in 409A specified employee. The fifth event is covered in 409A change in control.

An unforeseeable emergency has a strict test. The regulation names illness or an accident in your family, the loss of property to a casualty and similar events beyond your control. Imminent foreclosure or eviction, medical bills and funeral costs may qualify. Payment is limited to what the need requires. It is not allowed if insurance, selling assets or stopping your deferrals could cover the need.

Private-company pay is often promised “at an IPO or a sale.” A sale can be a change in control. An IPO is not on the list of six events, so a plan cannot simply pay deferred pay “on the IPO.”

Such awards usually work another way. The regulation lets completing an IPO serve as a vesting condition. If the right vests at the IPO and is paid soon after, the payment is a short-term deferral and 409A does not apply at all. The deadline is the 15th day of the third month after the year it vests. This is how many double-trigger RSUs are designed. If the award may pay later than that, it needs one of the six events.

An employee at a private company has $200,000 of vested deferred pay. She files taxes on a calendar year. The table shows seven ways her plan could set the payment.

Take the first row. The payment is on time anywhere from December 16, 2028, 30 days before the date, to December 31, 2029, the end of that tax year. A payment in October 2028 would be an early payment and a 409A failure. On $200,000, the 20% additional tax alone would be $40,000, plus income tax and interest.

One early payment is allowed in any case. If her whole balance were $20,000, the plan could pay it out in one sum. That holds because $20,000 is below the $24,500 limit for 2026.

• Paying on an IPOAn IPO is not one of the six events. It works only as a vesting condition for a short-term deferral.
• Leaving the date to discretionA payment the board or the employee can time is not on a permitted schedule.
• Paying early as a favorPaying before the date, beyond 30 days, is a prohibited acceleration unless a listed exception applies.
• Stretching “emergency”A home purchase or tuition does not qualify, and the payout is capped at the amount needed.
• Using a non-qualifying deal as a change in controlA minority investment or a partial asset sale below the thresholds is not a payment event.

Payment events are one of three 409A rule families, with elections and the ban on early payment. For the whole set, see Section 409A. For what a failure costs, see 409A penalties. For severance, see 409A and severance pay. For awards that often raise these questions, see RSU vs stock options.
