Updated July 29, 2026. Quick answer: You can change it, but the price is steep. IRC §409A(a)(4)(C) requires that a subsequent election not take effect for at least 12 months, and that the payment be deferred at least five additional years from when it would otherwise have been made. For a payment on a fixed schedule there is a further rule: the election must be made at least 12 months before the first scheduled payment.
The three conditions
| §409A(a)(4)(C) | Requirement |
|---|---|
| (i) | The election “may not take effect until at least 12 months after the date on which the election is made” |
| (ii) | The payment must be “deferred for a period of not less than 5 years from the date such payment would otherwise have been made” |
| (iii) | For a payment at a specified time or fixed schedule, the election “may not be made less than 12 months prior to the date of the first scheduled payment” |
The five-year push-back does not apply to payments on death, disability or an unforeseeable emergency. It does apply to separation from service, a specified time or schedule, and a change in control — which covers essentially every planned payout.
So the fix for a bad schedule is available and expensive. If you elected a five-year payout and now realise it fails the federal ten-year test, you can re-defer — but you wait a year for the election to bite and then push the whole payment out five more years. That may still be worth it against a large state tax. It has to be decided well before the first payment, not after.
A quirk of the enacted text worth knowing if you read it yourself. Clause (ii) refers to a payment “not described in clause (ii)” — the internal reference is to paragraph (2)(A)(ii), disability, not to itself. It reads like a typo and it is the law as written. Do not assume a source that quotes it that way has made an error.
