When you inherit an IRA from someone who had already inherited it, you do not get a fresh distribution schedule. As the successor beneficiary in a double inherited IRA, you step into whatever timeline was already running for the first beneficiary, and double inherited IRA rules use that existing schedule to decide how quickly the account must be emptied and whether annual required minimum distributions apply along the way. Get the timeline wrong and the IRS can impose a 25% excise tax on any amount that should have come out but didn’t.1Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs
The Clock Does Not Reset
The single concept that governs every double inherited IRA: the successor beneficiary cannot restart the distribution clock. There is no option to use your own life expectancy, elect a new 10-year period, or otherwise begin fresh. You continue whatever schedule the first beneficiary was already following. Final IRS regulations published in 2024 and effective for calendar years beginning January 1, 2025 formalized this framework after years of proposed guidance.2Internal Revenue Service. Internal Revenue Bulletin 2024-33
What “the existing schedule” actually looks like depends on which beneficiary category the first beneficiary fell into. That single classification controls how many years you have left, whether you owe annual RMDs, and how those RMDs are calculated.
If the First Beneficiary Was an Eligible Designated Beneficiary
An eligible designated beneficiary (EDB) is someone who qualified to stretch distributions over their own life expectancy: a surviving spouse, a minor child of the original owner (until age 21), a disabled or chronically ill individual, or a person no more than 10 years younger than the original owner.3Internal Revenue Service. Retirement Topics – Beneficiary This is the one scenario in which the successor beneficiary gets a defined window of their own.
When an EDB dies before the account has been fully distributed, the remainder must be paid out within 10 years of the EDB’s death. IRS Notice 2024-35 restates this directly: the successor beneficiary of an EDB “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 is not as free as it sounds. If the original IRA owner had already reached their required beginning date at death, you must also take annual RMDs during years one through nine of the 10-year window, with the balance emptied by December 31 of year ten. If the original owner died before that date, no annual minimums apply, but the full liquidation deadline still stands. The required beginning date is currently April 1 of the year after the owner turns 73.1Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs
If the First Beneficiary Was a Designated Beneficiary Under the 10-Year Rule
If the first beneficiary was a non-EDB individual (most adult children fall here), they were already subject to a 10-year deadline measured from the original owner’s death. As successor, you finish out whatever remains of that original 10-year window. If the first beneficiary died in year 4, you have 6 years left. Not 10.
Whether annual RMDs are required during those remaining years depends on the original owner’s status at death. If the original owner died on or after their required beginning date, the final regulations confirm that annual RMDs continue in each year up to the deadline, with full distribution in the final year.4Internal Revenue Service. Notice 2024-35 – Certain Required Minimum Distributions for 2024 If the original owner died before that date, no annual minimums apply, but the account must still be liquidated on time.
This is where successor beneficiaries get caught. They assume the 10-year clock restarts. It doesn’t. The measurement runs from the original owner’s death, and time already elapsed is gone.
If the First Beneficiary Was a Non-Designated Beneficiary
When the first “beneficiary” was an entity (an estate, a charity, or a trust that didn’t qualify as see-through), pre-SECURE Act distribution rules apply regardless of when the original owner died.3Internal Revenue Service. Retirement Topics – Beneficiary
If the original owner died before their required beginning date, the 5-year rule applies: the entire account must be emptied within five years of that owner’s death.5Internal Revenue Service. Required Minimum Distributions for IRA Beneficiaries When the entity later distributes the IRA out to you as an individual, you must finish within that original 5-year window. If the original owner died on or after their required beginning date, distributions continue based on the original owner’s remaining life expectancy, with the divisor reduced by one each year.
Either way, no switch to your own life expectancy is available.
The Spousal Rollover Changes Everything
One situation resets the entire framework: when the first beneficiary was a surviving spouse who elected to treat the inherited IRA as their own. A surviving spouse can roll inherited IRA assets into their own IRA, and once they do, the account is no longer inherited at all. The spouse takes RMDs under standard rules based on their own age using the Uniform Lifetime Table.
When that spouse later dies, their beneficiaries inherit as if the spouse were the original owner. Everything resets. EDBs get the life-expectancy stretch, designated beneficiaries get a full 10-year window from the spouse’s death, and non-designated beneficiaries get the 5-year rule or the deceased spouse’s remaining life expectancy. This is enormously valuable: the successor’s clock runs from the spouse’s death, not from the original owner’s.
If the surviving spouse instead kept the account as an inherited IRA and took life-expectancy distributions, no reset occurs. You are back in the EDB scenario above, with 10 years measured from that spouse’s death.
How to Calculate Your RMD
Which table you use depends on the track the first beneficiary was on. If the first beneficiary was an EDB taking life-expectancy distributions, you continue using that beneficiary’s life expectancy factor from the Single Life Expectancy Table (Table I in IRS Publication 590-B).6Internal 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 from that factor for each subsequent year.
The annual RMD equals the prior year’s December 31 balance divided by that remaining life expectancy factor. Even with a 10-year deadline overhead, you must still take at least the calculated minimum each year if the original owner died after their required beginning date. Withdrawing more than the minimum is always allowed.
If the first beneficiary was a designated beneficiary under the 10-year rule and the original owner died after their required beginning date, you continue annual RMDs in each year remaining before the deadline.4Internal Revenue Service. Notice 2024-35 – Certain Required Minimum Distributions for 2024 If the original owner died before that date, no annual minimums apply.
Missing an RMD triggers a 25% excise tax on the shortfall. That drops to 10% if you correct the error within two years by withdrawing the missed amount and filing Form 5329.1Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs The compressed timelines make year-end misses a real risk, especially while custodian transfers are still in progress.
Inherited Roth IRAs Follow the Same Timeline
A double inherited Roth IRA uses the same distribution timelines as a traditional one. The 10-year rule, the remaining-years calculation, and the pre-RBD versus post-RBD distinction all apply.3Internal Revenue Service. Retirement Topics – Beneficiary Qualified distributions come out tax-free, though earnings can 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 are always tax-free.
Because Roth IRAs have no required beginning date for the original owner, the “died before RBD” branch always applies. No annual RMDs are required during the 10-year window. You can let the balance grow tax-free for up to ten years and withdraw it all at the end, which makes an inherited Roth the account you generally want to touch last.
Account Titling and Transfers
Proper titling keeps the IRA from being treated as an immediate taxable distribution. The account name must identify the original owner, the first beneficiary, and you as successor. A typical format:
“Jane Doe DCD 01/15/2021, FBO John Doe DCD 03/10/2023, FBO Sally Smith, Beneficiary.”
Custodians vary in exact conventions, but both decedents’ names and dates of death and the successor beneficiary’s name all need to appear. If the title doesn’t reflect the inherited status, the custodian or the IRS can treat the funds as a current-year distribution taxable in full.
The transfer itself must be a direct trustee-to-trustee movement. The 60-day rollover window that applies to living account owners is not available to non-spouse beneficiaries. Taking a check and redepositing it within 60 days will not save the account; the entire balance becomes taxable. Distribution Code 4 on Form 1099-R does protect a successor under 59½ from the 10% early withdrawal penalty, but the ordinary income tax on the full balance remains. Custodians typically require death certificates for both the original owner and the first beneficiary, along with the beneficiary designation forms naming you.
Tax Reporting and the IRD Deduction
Distributions from a double inherited traditional IRA are taxed as ordinary income at your marginal rate. Every dollar withdrawn from a pre-tax account adds to taxable income for that year, and larger required withdrawals can push you into a higher bracket.
Each year’s distributions appear on Form 1099-R, with Box 7 showing Distribution Code 4 for a death distribution.7Internal Revenue Service. 2025 Instructions for Forms 1099-R and 5498 Code 4 exempts the payment from the 10% early withdrawal penalty. Report the gross distribution on Form 1040 line 4a and the taxable portion on line 4b.8Internal Revenue Service. 2025 Instructions for Form 1040
One deduction goes unclaimed often. If the first beneficiary’s estate owed federal estate tax and the inherited IRA was included in that taxable estate, you may claim an itemized deduction under IRC Section 691(c) for the estate tax attributable to the IRA.9Internal Revenue Service. Revenue Ruling 2005-30 This income-in-respect-of-a-decedent deduction prevents the same dollars from being taxed as part of the estate and again as your income.
The Section 691(c) deduction is claimed on Schedule A and is specifically carved out from the miscellaneous itemized deduction suspension under the Tax Cuts and Jobs Act, so it remains available through at least 2025.10Office 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. A tax professional can run the numbers using the estate’s return.
When a Trust Is the Successor Beneficiary
If the successor named on the account is a trust rather than an individual, classification gets more complicated. A trust defaults to non-designated beneficiary status (with the least favorable rules) unless it meets IRS “see-through” trust requirements: valid under state law, irrevocable upon the account owner’s death or by the time distributions must begin, and with all beneficiaries identifiable individuals. A copy of the trust document or a certified list of beneficiaries must reach the IRA custodian by October 31 of the year following the account owner’s death.
Even a qualifying see-through trust does not escape the 10-year rule when its beneficiaries are designated beneficiaries rather than EDBs. Trust structure controls how distributions flow: a conduit trust passes all IRA distributions straight through to the trust beneficiary, while an accumulation trust holds them inside the trust. Distributions retained inside an accumulation trust face compressed trust tax brackets, with the top 37% federal rate hitting at roughly $15,450 of income in 2026. That can make accumulation an expensive default.
If the trust fails the see-through requirements, it drops to non-designated status, meaning the 5-year rule or the original owner’s remaining life expectancy governs, depending on whether the owner died before or after their required beginning date. Fixing the trust structure is far easier before the first beneficiary dies than after.
Transition Relief Is Over
From 2021 through 2024, the IRS waived penalties for beneficiaries who missed annual RMDs under the 10-year rule when the original owner died after their required beginning date. Notice 2024-35 was the last in that series, confirming that final regulations would apply starting January 1, 2025.4Internal Revenue Service. Notice 2024-35 – Certain Required Minimum Distributions for 2024
For 2026 and beyond, the rules are settled. If the original owner died on or after their required beginning date and you’re subject to the 10-year rule as successor, annual RMDs are mandatory in years one through nine with full liquidation by the end of year ten.2Internal Revenue Service. Internal Revenue Bulletin 2024-33 Missing those annual distributions carries the full 25% penalty with no blanket waiver behind it. If you inherited during the transition period and deferred distributions on the assumption that annual RMDs were still uncertain, catch up with a tax advisor before the shortfalls compound.
