If you think you “missed the spousal IRA rollover deadline,” first identify which deadline you mean. That distinction matters because the 2024 final required-minimum-distribution regulations eliminated the broad calendar-year deadline that appeared in the earlier proposed regulations for a surviving spouse to elect to treat an inherited IRA as the spouse’s own. Current law instead uses a yearly timing rule and, in some late-election situations, requires certain amounts to be distributed as required minimum distributions before the election can apply to the remaining IRA.

A completely different deadline applies if money was actually paid to you. A distribution that is eligible for rollover generally must be contributed to the receiving IRA or plan within 60 days unless an automatic waiver, self-certification procedure, or IRS waiver applies. Self-certification under Revenue Procedure 2020-46 can help with some late 60-day rollovers, but it does not turn an otherwise ineligible distribution—such as an RMD—into a rollover-eligible amount.

There is no longer a single “later-of” election deadline

The 2022 proposed RMD regulations included a rule that would have required a surviving spouse to make the election to treat a deceased spouse’s IRA as the survivor’s own by the later of the end of the year the survivor reached a specified RMD age or the end of the year after the IRA owner’s death. That proposed timing rule generated comments because it could force an all-or-nothing decision even when the survivor had sensible reasons to remain a beneficiary for a period.

The final regulations, issued in 2024 as T.D. 10001 and generally applicable for RMD purposes beginning in 2025, removed that general deadline. The preamble explicitly says the final regulations eliminate the deadline described in the proposed regulations. In its place, Treasury adopted a yearly rule linked to the special catch-up calculation for hypothetical required minimum distributions.

That change is easy to miss because older articles, adviser memos, and even search snippets may still quote the proposed “later of” rule. For a current 2026 article, it is safer to start with the final regulation itself rather than treating the proposal as if it became law unchanged.

What the final regulation requires for a late election

Section 1.408-8(c) of the final regulations allows an eligible surviving spouse to elect to treat the spouse’s entire remaining beneficiary interest in the IRA as the spouse’s own. The spouse generally must be the sole beneficiary and have an unlimited right to withdraw amounts from the IRA for this particular election route.

The regulation then adds a timing limitation. If the special catch-up rule for hypothetical RMDs would apply had a distribution been made directly to the surviving spouse during that calendar year, the spouse cannot simply sweep the whole inherited balance into owner status without dealing with the amount treated as an RMD. The regulation provides an exception for a late election after those required amounts have been distributed.

In plain English, waiting does not necessarily destroy the owner-election option. But waiting until the spouse is in a year where owner-level RMD amounts should already have been coming out can reduce the portion eligible to be rolled or redesignated without first satisfying the RMD component. Required minimum distributions cannot be rolled over.

The 60-day deadline is a separate problem

Suppose instead that the inherited IRA custodian sent a check payable to the surviving spouse, the spouse deposited the money in a bank account, and the plan was to place the eligible amount into the spouse’s own IRA. That is a rollover-distribution problem. Publication 590-A generally requires an IRA distribution that is being rolled over to be contributed to the receiving retirement arrangement within 60 days of receipt.

A direct trustee-to-trustee transfer is different. When assets move directly between financial institutions without the spouse receiving the distribution, the 60-day clock generally is not the operational issue. This is one reason direct transfers are often cleaner: they reduce withholding, redeposit, and missed-deadline risks.

If the 60-day period expired, do not assume the money is permanently taxable. The IRS provides several forms of relief. Some situations qualify for an automatic waiver, and Revenue Procedure 2020-46 provides a self-certification process for listed reasons that prevented a timely rollover. A taxpayer can also request an IRS waiver through the applicable private-letter-ruling procedure when necessary.

What self-certification can and cannot do

Revenue Procedure 2020-46 permits a taxpayer to give a written certification to a plan administrator or IRA trustee stating that the 60-day rollover deadline was missed for one or more specified reasons. Those reasons include certain financial-institution errors and other circumstances described in the revenue procedure. The contribution generally must be made as soon as practicable after the impediment ends; IRS guidance says 30 days is ordinarily treated as satisfying that timing standard.

Self-certification is not an IRS determination that the rollover is valid. The receiving institution may rely on the certification for accepting and reporting the late contribution if it lacks actual knowledge to the contrary, but the IRS can later examine the transaction. The certification also addresses only the lateness problem. It does not cure a distribution that was never eligible for rollover.

That last limitation is critical for inherited accounts. An RMD cannot be rolled over. If part of the spouse’s distribution is treated as a required minimum distribution under the beneficiary or catch-up rules, a late-rollover certification cannot transform that part into an eligible rollover contribution.

A practical decision tree after a suspected missed deadline

First, ask whether any money or property was actually distributed to you. If no distribution occurred and the account is still held as an inherited IRA, you may not have a 60-day rollover problem at all. Instead, review whether you can now elect owner treatment under the current final regulations and whether any RMD must be taken first.

Second, if a distribution was made to you, identify the date you received it and whether it was rollover eligible. Separate any year-of-death RMD, beneficiary RMD, or other amount that the Code treats as non-rollover-eligible. Then count the 60-day period for the remaining eligible distribution.

Third, if the 60 days expired, compare the facts with the IRS automatic-waiver rules and Revenue Procedure 2020-46. Preserve evidence of the reason for the delay, the date the obstacle ended, and the date the contribution was completed. If the facts do not fit self-certification, ask a tax professional whether a private-letter-ruling waiver is appropriate.

Fourth, reconcile the reporting. A distribution may appear on Form 1099-R even if a valid rollover ultimately makes the taxable amount zero. A late rollover can create especially confusing reporting when the contribution occurs in a later calendar year, so the return should be prepared from the actual transaction and relief used, not merely from the box 2a amount on one form.

Example: no distribution, only a delayed owner election

Leah’s spouse died in 2025, leaving Leah as sole beneficiary of a traditional IRA. Leah kept the account in inherited status through 2027 because she wanted beneficiary access. In 2028 she decides she wants the IRA treated as her own. She finds an older article saying she missed a “year after death” election deadline.

That conclusion is not supported by the 2024 final regulations. Leah should instead apply the current section 1.408-8(c) timing rule. Depending on her age, the deceased spouse’s age and required beginning date, the distribution method previously used, and whether the hypothetical-RMD catch-up rule is triggered, she may need to distribute an RMD amount before owner treatment applies to the rest. But the old proposed deadline is not, by itself, the end of the analysis.

Example: distribution received 90 days ago

Marcus receives a rollover-eligible distribution from his deceased spouse’s IRA but does not deposit it into his own IRA for 90 days because the check was misplaced during a move. He cannot fix the transaction merely by calling it a spousal election. Because he received a distribution, the 60-day rollover rules apply to the eligible portion.

Marcus should review Revenue Procedure 2020-46 to see whether his facts fit a listed self-certification reason and whether he acted promptly after the reason ceased. He should also determine whether any part of the payment was an RMD. Even if self-certification is available for the late eligible portion, an RMD remains outside rollover treatment.

Do not mix up three different dates

Inherited IRA administration can involve at least three separate timing concepts: the deadline for an annual beneficiary RMD, the final deadline under a 10-year or other distribution rule when applicable, and the 60-day deadline after personally receiving a rollover-eligible distribution. The final regulations add a fourth timing question for a spouse making a later owner election in a year affected by hypothetical-RMD catch-up.

A custodian representative may use the word “deadline” to describe an internal paperwork cutoff as well. Internal processing dates can matter operationally, but they do not replace the Code and regulations. Ask the representative to identify whether the date is a tax-law requirement, a plan or custodian processing requirement, or simply a recommended date for year-end completion.
