If you’ve been named on someone’s IRA or 401(k), the designated beneficiary IRA distribution rules sort you into one of three groups, and that grouping decides everything about your timeline. A surviving spouse gets the widest set of choices, including rolling the money into their own IRA. A small category called eligible designated beneficiaries can still stretch withdrawals over their own life expectancy. Everyone else — most adult children, siblings, and friends — falls under the 10-year rule and must empty the account by December 31 of the tenth year after the owner’s death.
Your category locks in on the date the account owner died, so the first job is figuring out which group you’re in. From there, the rules follow.
Who Counts as a Designated Beneficiary
The IRS treats a designated beneficiary as an individual named by the account owner (or identified through the plan’s default terms) to receive the assets after death.1Office of the Law Revision Counsel. 26 USC 401 – Qualified Pension, Profit-Sharing, and Stock Bonus Plans The word “individual” is the key. A living person qualifies. An estate, a charity, or a trust named directly on the beneficiary form does not, even when they can technically receive the funds. Those non-individual beneficiaries follow shorter, harsher timelines that fall outside this article; if you’re a trustee or an executor rather than a named person, the rules below aren’t yours.
Individual designated beneficiaries split into three groups:2Internal Revenue Service. Retirement Topics – Beneficiary
- Surviving spouse, with the most flexible options.
- Eligible designated beneficiary (EDB): a narrow group of non-spouse individuals who can still stretch distributions over their own life expectancy. This covers minor children of the account owner, people who are disabled or chronically ill, and anyone not more than 10 years younger than the deceased owner.
- Non-eligible designated beneficiary (NEDB): everyone else. Subject to the 10-year rule.
Distribution Options for a Surviving Spouse
A spouse has three paths, and age and cash needs usually decide which one fits.
Rolling the Account Into Your Own IRA
The most powerful option is a spousal rollover: treating the inherited account as your own. You combine the assets with your own retirement funds, and required minimum distributions don’t start until you reach your own RMD age. For 2026, that’s age 73 for people born between 1951 and 1959, and 75 for those born in 1960 or later.3Congress.gov. Required Minimum Distribution (RMD) Rules for Original Owners The rollover is tax-free and effectively resets the clock, maximizing tax-deferred growth. You also control the investments and can name new beneficiaries.
The catch is age. If you’re younger than 59½ and roll the funds into your own IRA, any withdrawal before that age triggers a 10% early distribution penalty on top of ordinary income tax. For a younger spouse who needs cash now, this option can backfire.
Keeping It as an Inherited IRA With the Section 327 Election
SECURE 2.0’s Section 327, effective for distributions starting in 2024, added a middle path. You keep the account as an inherited IRA but elect to be treated as the deceased owner for RMD purposes.4Internal Revenue Service. Internal Revenue Bulletin 2024-33 – Section 327 Election Proposed Regulations When the account owner died before their required beginning date, this treatment applies automatically with no formal election required.
Two advantages over a straight rollover: distributions from an inherited IRA are never subject to the 10% early withdrawal penalty regardless of your age, and you can delay RMDs until the year the deceased owner would have reached their RMD age. You also get to use the Uniform Lifetime Table, which produces smaller annual required withdrawals than the Single Life Table.
You can still roll the remaining balance into your own IRA later if circumstances change.
Taking Standard Beneficiary Treatment
A spouse can also just follow the same 10-year rule that applies to non-eligible designated beneficiaries. This rarely makes sense for tax planning, but it’s on the menu.
The 10-Year Rule for Non-Eligible Designated Beneficiaries
Most adult children, siblings, and other non-spouse individuals who inherited after 2019 are non-eligible designated beneficiaries. The entire account must be empty by December 31 of the tenth calendar year after the owner’s death.5Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs An account inherited in 2025 must be fully liquidated by the end of 2035.
This replaced the old stretch IRA strategy, which let non-spouse beneficiaries take distributions over their own life expectancy, sometimes for 40 or 50 years. The compressed window means more taxable income squeezed into a shorter period.
Do You Owe Annual RMDs During Years One Through Nine?
It depends on whether the original account owner had reached their required beginning date (RBD) before dying. If the owner died on or after their RBD, you owe annual minimum distributions in each of the first nine years, with the remainder due in year ten. If the owner died before their RBD, no annual distributions are required, and you can take money out on any schedule you like as long as the account is empty by the end of year ten.
This distinction confused everyone for years after the SECURE Act passed. The IRS waived penalties for missed annual RMDs from 2021 through 2024 while it finalized the rules.6Internal Revenue Service. Notice 2024-35 – Certain Required Minimum Distributions for 2024 That relief has ended. Starting with the 2025 tax year, beneficiaries who owe annual RMDs during the 10-year window must take them or face penalties.
Timing Withdrawals to Manage Taxes
Taking the whole balance as a lump sum runs every dollar through ordinary income tax in a single year, which can push you into a much higher marginal bracket. Spreading distributions across the window generally produces better results, though the right pattern depends on your projected income each year. If you expect a few low-income years — a career change, an early retirement, unpaid leave — you might front-load distributions into those years to use lower brackets.
Inherited Roth IRAs are still subject to the 10-year rule, but withdrawals come out tax-free. The typical move with an inherited Roth is to let it grow untouched and distribute everything in year ten, since the growth isn’t taxed either.
Eligible Designated Beneficiaries and the Life-Expectancy Stretch
Eligible designated beneficiaries are the only non-spouse individuals who can still stretch distributions over their own life expectancy, taking annual RMDs based on their age rather than emptying the account within 10 years. The categories are narrow:2Internal Revenue Service. Retirement Topics – Beneficiary
- Minor children of the account owner. Only the owner’s own children qualify, not grandchildren, nieces, nephews, or stepchildren unless legally adopted.
- Disabled individuals unable to engage in any substantial gainful activity because of a physical or mental impairment expected to be long-lasting or indefinite. Anyone already receiving Social Security disability benefits or Supplemental Security Income when the owner died automatically qualifies.
- Chronically ill individuals unable to perform at least two activities of daily living for an indefinite period expected to be lengthy.
- Individuals not more than 10 years younger than the deceased owner, such as a close-in-age sibling or a friend born within a decade of the owner.
Documentation Deadlines
Claiming EDB status based on disability or chronic illness requires medical documentation. Self-certification is not accepted. A licensed healthcare practitioner must certify the condition, and the beneficiary must have been disabled or chronically ill at the time the account owner died. The documentation must be submitted by October 31 of the year after the owner’s death. Beneficiaries receiving Social Security disability don’t need separate medical certification but still need to show proof of those benefits.
When a Minor Child Turns 21
The rule for minor children is a hybrid. Life-expectancy RMDs apply while the child is under 21. On the child’s 21st birthday, the 10-year clock starts, and the account must be fully distributed by the end of the tenth year after that. A child who inherits at age 10 takes life-expectancy RMDs for 11 years, then has until age 31 to empty the account. Total deferral can reach roughly 20 years — better than a straight 10, well short of the old stretch.
The September 30 Beneficiary Determination Date
The beneficiary determination date is September 30 of the year after the account owner’s death.2Internal Revenue Service. Retirement Topics – Beneficiary The IRS looks at who remains as a beneficiary on that date, not just who was named on the original form. If one of several named beneficiaries disclaims their share or cashes out entirely before September 30, they’re removed from the calculation, which can change the distribution rules for everyone left.
This matters most when an account names both individual and non-individual beneficiaries. If a charity is named alongside an adult child and the charity receives its share before September 30, the child is treated as the sole designated beneficiary and gets the 10-year rule instead of the shorter timeline that applies when no designated beneficiary exists.
Splitting an Account Among Multiple Beneficiaries
When multiple individuals inherit the same account, each can establish a separate inherited IRA by December 31 of the year after the owner’s death. Splitting the account lets each beneficiary use their own distribution schedule. Miss that deadline, and all beneficiaries can end up locked into the oldest beneficiary’s life expectancy. For NEDBs, the 10-year rule still applies uniformly, but the failure to split can also prevent a surviving spouse from moving their share into their own IRA.
Penalties for Missing an RMD
Failing to take a required distribution triggers a 25% excise tax on the amount you should have withdrawn but didn’t.7Internal Revenue Service. Retirement Topics – Required Minimum Distributions (RMDs) Catch it and take the missed amount within two years, and the penalty drops to 10%. If you missed for reasonable cause and can show it to the IRS, the penalty can be waived entirely.
This applies to inherited account RMDs the same as it does to RMDs from your own accounts. For NEDBs who inherited from someone who died after their RBD, the annual RMD requirement during the 10-year window is easy to overlook, especially after the four-year IRS relief period. That grace ended with the 2024 tax year. Miss a required annual distribution for 2025 or later, and the penalty is on the table.
