If you’ve inherited an IRA from someone who had already inherited it from the original owner, you’re a successor beneficiary, and the double inherited IRA rules are strict about one thing: you don’t get a fresh timeline. You step into whatever distribution schedule the first beneficiary was already following, measured from the original owner’s death, not yours. The one meaningful exception is when the first beneficiary belonged to a special category called an eligible designated beneficiary, in which case you get 10 years measured from that person’s death. Missing a required withdrawal triggers a 25% excise tax on the shortfall, so getting the timeline right matters immediately.1Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs
Your Timeline Depends on What the First Beneficiary Was
The IRS sorts beneficiaries into three categories, and the category the first beneficiary occupied dictates what happens to you. There is no option to use your own life expectancy, no option to elect a new 10-year period, no way to restart the clock.2Internal Revenue Service. Internal Revenue Bulletin 2024-33 Figure out which of the three scenarios applies to you, and the rest of the planning falls into place.
First Beneficiary Was an Eligible Designated Beneficiary
Eligible designated beneficiaries (EDBs) include the surviving spouse, a minor child of the original owner (until age 21), a disabled or chronically ill individual, and anyone no more than 10 years younger than the original owner. EDBs were allowed to stretch distributions over their own life expectancy.
When an EDB dies before the account is fully distributed, federal law requires the remainder to be paid out within 10 years of the EDB’s death.3Office of the Law Revision Counsel. 26 U.S. Code 401 – Qualified Pension, Profit-Sharing, and Stock Bonus Plans IRS Notice 2024-35 confirms that the successor “will be subject to a requirement that the remainder of that individual’s portion be distributed within 10 years of the eligible designated beneficiary’s death.”4Internal Revenue Service. Notice 2024-35 – Certain Required Minimum Distributions for 2024
Ten years sounds generous, but if the original IRA owner died on or after their required beginning date, you also have to take annual required minimum distributions in years one through nine of the window. The full remaining balance must come out by December 31 of year ten. If the original owner died before reaching that date, no annual minimums apply during the 10 years, but the account still has to be empty by the deadline.
First Beneficiary Was a Designated Beneficiary Under the 10-Year Rule
If the first beneficiary was an ordinary designated beneficiary (most adult children of the original owner land here), they were already on a 10-year clock measured from the original owner’s death. You finish out whatever time is left. If the first beneficiary died in year 4, you have 6 years, not 10.
Whether you have to take annual RMDs during those remaining years again depends on when the original owner died relative to their required beginning date. If the owner died on or after that date, the final regulations require annual RMDs through the remaining years, with full liquidation by the end of year ten.4Internal Revenue Service. Notice 2024-35 – Certain Required Minimum Distributions for 2024 If the owner died before that date, no annual minimums are required, but the deadline still stands.
This is where successor beneficiaries most often get caught off guard. The 10 years do not reset. The IRS measures from the original owner’s death, and the time that has already elapsed is gone.
First Beneficiary Was a Non-Designated Beneficiary
If the IRA passed through an entity like an estate or a trust that didn’t qualify as a see-through trust, the first beneficiary was a non-designated beneficiary and followed pre-SECURE Act rules.5Internal Revenue Service. Retirement Topics – Beneficiary If the original owner died before their required beginning date, the entire account has to be emptied within 5 years of the owner’s death.6Internal Revenue Service. Required Minimum Distributions for IRA Beneficiaries If the owner died on or after that date, distributions continue over the original owner’s remaining life expectancy, reducing the divisor by one each year.
Either way, you can’t switch to your own life expectancy. You finish out the schedule the first beneficiary was on.
The Spousal Rollover Exception That Resets Everything
One situation genuinely changes the analysis. If the first beneficiary was a surviving spouse who elected to roll the inherited IRA into their own IRA, the account stopped being an inherited IRA at that moment. The spouse took RMDs as the owner, under the Uniform Lifetime Table based on their own age.
When that spouse later dies, their beneficiaries inherit as if the spouse were the original owner. The whole classification framework starts over. If the spouse died after 2019, their beneficiaries face the same SECURE Act rules that apply to any original owner’s beneficiaries: EDBs can stretch, designated beneficiaries get a full 10 years from the spouse’s death, and non-designated beneficiaries get the 5-year rule or the deceased spouse’s remaining life expectancy.
If instead the surviving spouse kept the account titled as inherited and was taking life-expectancy distributions as an EDB, no reset happens. You fall under the standard 10-year successor rule described above, measured from the spouse’s death.
Calculating Your Required Minimum Distribution
If the first beneficiary was an EDB taking life-expectancy distributions, you continue using that person’s life expectancy factor from the Single Life Expectancy Table in IRS Publication 590-B.7Internal Revenue Service. Retirement Topics – Required Minimum Distributions (RMDs) You look up the factor based on the first beneficiary’s age in the year after the original owner’s death, then subtract one for each subsequent year. The annual RMD is the prior December 31 balance divided by that factor.
If the first beneficiary was on the 10-year rule and the original owner died after their required beginning date, you continue annual RMDs in the years remaining before the deadline.4Internal Revenue Service. Notice 2024-35 – Certain Required Minimum Distributions for 2024 If the owner died before that date, no annual minimum applies.
The current required beginning date is April 1 of the year after the owner turns 73, set by the SECURE 2.0 Act of 2022.1Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs Missing an RMD triggers a 25% excise tax on the shortfall. The penalty drops to 10% if you correct the shortfall within two years by withdrawing the missed amount and filing Form 5329. Account transfers between custodians sometimes drag past year-end, so a successor who inherits late in the calendar year should confirm whether a distribution for that year is already required.
Titling the Account and Moving the Money
Proper titling keeps the IRA from being treated as a taxable distribution the moment it moves. A double inherited IRA has to identify the original owner, the first beneficiary, and you. The standard format reads something like: “Jane Doe DCD 01/15/2021, FBO John Doe DCD 03/10/2023, FBO Sally Smith, Beneficiary.” Custodians vary slightly, but both decedents’ names and dates of death have to appear, followed by yours.
The transfer itself has to happen as a direct trustee-to-trustee transfer. The 60-day rollover window does not apply to non-spouse beneficiaries, so if you take a physical distribution and try to redeposit it, the entire balance becomes taxable. Code 4 on the Form 1099-R will protect you from the 10% early withdrawal penalty if you’re under 59½, but the income tax hit stays. Custodians will typically ask for death certificates for both the original owner and the first beneficiary, along with the beneficiary designation forms naming you as successor.
Tax Reporting and the Deduction People Miss
Distributions from a double inherited traditional IRA are ordinary income at your marginal rate. The custodian reports each year’s distribution on Form 1099-R with Distribution Code 4 in Box 7, which signals a distribution due to death and exempts the payment from the 10% early withdrawal penalty.8Internal Revenue Service. 2025 Instructions for Forms 1099-R and 5498 You report the gross distribution on Form 1040, line 4a, with the taxable portion on line 4b.9Internal Revenue Service. 2025 Instructions for Form 1040
The deduction many successors overlook is the income-in-respect-of-a-decedent (IRD) deduction under IRC Section 691(c). If the first beneficiary’s estate owed federal estate tax and the inherited IRA was part of that taxable estate, you can deduct the portion of the estate tax attributable to the IRA.10Internal Revenue Service. Revenue Ruling 2005-30 This prevents the same dollars from being taxed as part of the estate and again as income to you.
You claim the IRD deduction as an itemized deduction on Schedule A. Congress carved it out from the definition of miscellaneous itemized deductions, so the Tax Cuts and Jobs Act suspension doesn’t eliminate it; the deduction remains available through at least 2025, when the TCJA suspension is currently scheduled to expire.11Office of the Law Revision Counsel. 26 U.S. Code 67 – 2-Percent Floor on Miscellaneous Itemized Deductions The calculation is proportional to your share of the estate’s IRD items, and running the numbers usually requires a copy of the estate’s tax return.
Inherited Roth IRAs: Same Clock, Better Tax Outcome
The timeline rules are identical for a double inherited Roth IRA. The 10-year rule, the remaining-years math, and the pre-RBD/post-RBD distinction all apply the same way.5Internal Revenue Service. Retirement Topics – Beneficiary The difference is on the tax side: qualified distributions come out tax-free. Because Roth IRAs have no required beginning date for the original owner, you’re always in the “died before RBD” bucket, meaning no annual RMDs during the 10-year window. You can let the balance grow and take it all in year ten.
One caveat: earnings may be taxable if the Roth account is less than five years old, measured from January 1 of the year the original owner first funded any Roth IRA. Contributions always come out tax-free regardless of account age.
If a Trust Is the Successor Beneficiary
Naming a trust as successor complicates things. A trust is not an individual, so by default it’s a non-designated beneficiary stuck with the least favorable rules. A trust that meets the IRS’s see-through requirements can push through to its underlying individual beneficiaries, but the trust still has to be valid under state law, irrevocable upon the account owner’s death, and populated entirely by identifiable individual beneficiaries, with documentation provided to the custodian by October 31 of the year following the account owner’s death.
Even a qualifying see-through trust is subject to the 10-year rule unless its beneficiaries are EDBs. Conduit trusts pass IRA distributions straight through to the beneficiary; accumulation trusts hold them inside the trust, where compressed trust tax brackets apply (the top 37% federal rate kicks in at roughly $15,450 of income in 2026). Fixing a trust structure before the first beneficiary dies is far easier than trying to repair it afterward.
Transition Relief Has Ended
From 2021 through 2024, the IRS waived penalties for beneficiaries who missed annual RMDs under the 10-year rule when the original owner had died after their required beginning date. Notice 2024-35 was the last waiver, confirming that the final regulations apply starting January 1, 2025.4Internal Revenue Service. Notice 2024-35 – Certain Required Minimum Distributions for 2024
For 2026 and beyond, there is no blanket relief. If the original owner died on or after their required beginning date and you’re subject to the 10-year rule as a successor, annual RMDs in years one through nine are mandatory, with full liquidation by the end of year ten.2Internal Revenue Service. Internal Revenue Bulletin 2024-33 A missed distribution now carries the full 25% penalty. If you inherited during the transition years and deferred distributions on the assumption that nothing was due, work with a tax advisor to catch up before the shortfall grows.
