An eligible designated beneficiary is someone who inherits an IRA or 401(k) and belongs to one of five categories that federal law lets take withdrawals over their own life expectancy, rather than emptying the account within ten years like most other heirs. The category is set by the SECURE Act of 2019, and it is determined as of the date the original account owner dies. If your health or age changes after that date, your status doesn’t change with it.
The practical stakes are large. An ordinary designated beneficiary has to pull the whole balance out within a decade, which often bunches taxable income into years when the heir is still working and in a higher bracket. An eligible designated beneficiary can spread that income across decades and keep the rest of the account growing tax-deferred in the meantime.
The Five Categories That Qualify
Internal Revenue Code Section 401(a)(9)(E)(ii), added by the SECURE Act, recognizes exactly five types of people.1Federal Register. Required Minimum Distributions
- A surviving spouse of the account owner.
- A minor child of the account owner. Grandchildren, stepchildren, nieces, and nephews do not qualify under this category.
- A disabled individual, measured by the tax code’s standard.
- A chronically ill individual, measured by the tax code’s standard.
- A person not more than ten years younger than the account owner, regardless of family relationship.
Anyone named as a beneficiary who does not fit one of these five is a plain “designated beneficiary” and falls under the ten-year rule.2Internal Revenue Service. Retirement Topics – Beneficiary
The Ten-Years-Younger Rule
The fifth category is the one people miss. It has nothing to do with being a relative. The IRS uses actual dates of birth, not year-to-year comparisons. If the owner was born on October 1, 1953, any beneficiary born on or before October 1, 1963, qualifies.1Federal Register. Required Minimum Distributions Siblings, domestic partners, and close friends near the deceased’s age often land here.
How the Stretch Works
Eligible designated beneficiaries can take annual withdrawals based on their own life expectancy using the IRS Single Life Expectancy Table in Publication 590-B. You divide the account balance by the divisor for your age. A 30-year-old uses 55.3, so only about 1.8% of the account has to come out the first year. A 50-year-old uses 36.2. A 70-year-old uses 18.8.3Internal Revenue Service. Publication 590-B, Distributions from Individual Retirement Arrangements (IRAs) Each year after that, the divisor drops by one.
When the owner died before their required beginning date, an eligible designated beneficiary can either take life expectancy distributions or use the ten-year rule. Life expectancy distributions have to begin by December 31 of the year after the owner’s death. Miss that date and you’re generally stuck with the ten-year rule.
The required beginning date matters because it changes your options. In 2026, most owners have to start their own required minimum distributions at age 73; that rises to 75 starting in 2033.4Internal Revenue Service. Retirement Topics – Required Minimum Distributions (RMDs) If the owner died after that date, the “at least as rapidly” rule kicks in: you don’t get to choose, and you must take annual life expectancy distributions starting the year after the death.5Internal Revenue Service. Notice 2024-35, Certain Required Minimum Distributions for 2024
Roth IRA owners are never required to take lifetime distributions, so they’re always treated as having died before the required beginning date. An eligible designated beneficiary who inherits a Roth keeps the full choice between the stretch and the ten-year rule.
Surviving Spouses Get More
Spouses have the widest set of options, and one no other category can use: rolling the inherited account into their own IRA. After a rollover, the account follows the spouse’s own required minimum distribution schedule, and the spouse names their own beneficiaries.2Internal Revenue Service. Retirement Topics – Beneficiary The rollover works whether the owner died before or after the required beginning date.
Whether the spouse is the sole beneficiary is determined by September 30 of the year following the owner’s death.2Internal Revenue Service. Retirement Topics – Beneficiary If several beneficiaries share the account and it isn’t split into separate inherited IRAs by that date, the spouse can lose access to some of the preferential options.
SECURE 2.0 added another choice starting in 2024: a surviving spouse can elect to be treated as the deceased owner for distribution purposes. That can help a younger spouse delay withdrawals until the year the deceased would have reached the required beginning date age. The election is irrevocable, and the IRS is still finalizing procedures for making it.
Minor Children Age Out
A minor child of the account owner can take stretch distributions, but the status has a built-in end. SECURE 2.0 fixed the age of majority at 21 for this purpose, no matter what any state considers adulthood. Once the child turns 21, the stretch ends and a fresh ten-year clock starts. The account has to be fully distributed by December 31 of the year containing the tenth anniversary of that birthday, meaning it must be empty by the child’s 31st birthday year.3Internal Revenue Service. Publication 590-B, Distributions from Individual Retirement Arrangements (IRAs)
Two traps here. Only the account owner’s own children qualify. Grandchildren, stepchildren, and foster children do not. And the federal 21-year-old threshold controls, even in states where the age of majority is 18.
Proving Disability or Chronic Illness
These two categories require meeting a specific tax-code standard, not just having a serious health condition.
The disability standard, drawn from IRC Section 72(m)(7), is being unable to engage in any substantial gainful activity because of a medically determinable physical or mental impairment expected to result in death or to be of long-continued and indefinite duration.1Federal Register. Required Minimum Distributions The analysis considers the nature and severity of the impairment together with the person’s education, training, and work experience.
The chronic illness standard requires being unable to perform at least two activities of daily living (eating, bathing, dressing, toileting, transferring, or continence) without substantial assistance, or needing constant supervision because of severe cognitive impairment. A licensed health care practitioner must certify the condition as indefinite.
The documentation deadline is strict. A physician’s certification must reach the plan administrator by October 31 of the year following the owner’s death.6Internal Revenue Service. Internal Revenue Bulletin 2024-33 For owners who died between 2020 and 2023, the IRS extended that deadline to October 31, 2025. Miss it and the beneficiary can lose eligible designated beneficiary status and drop onto the ten-year schedule. Keep the medical records; if distributions are audited later, they are the primary defense.
Trusts as Beneficiaries
Naming a trust as the beneficiary is common when the intended heir is disabled or a minor, but stretch treatment only flows through if the trust qualifies as a “see-through trust.” Four requirements apply:6Internal Revenue Service. Internal Revenue Bulletin 2024-33
- Valid under state law, or would be valid if funded.
- Irrevocable at the account owner’s death.
- All beneficiaries who could receive benefits are identifiable from the trust document.
- A copy of the trust, or a complete beneficiary list with enough detail to determine entitlements, reaches the plan administrator.
When a trust benefits a disabled or chronically ill person alongside healthy beneficiaries, an “applicable multi-beneficiary trust” structure can preserve full stretch treatment for the disabled or chronically ill beneficiary, provided no one else can receive distributions until that person dies. The other beneficiaries then fall under the ten-year rule after the eligible designated beneficiary’s death.6Internal Revenue Service. Internal Revenue Bulletin 2024-33 Getting this drafting wrong sends the whole trust to the ten-year rule.
What Happens When an Eligible Designated Beneficiary Dies
The status does not pass to the next person in line. When an eligible designated beneficiary dies while still taking stretch distributions, the successor beneficiary has to empty the remaining balance by December 31 of the year containing the tenth anniversary of the eligible designated beneficiary’s death.3Internal Revenue Service. Publication 590-B, Distributions from Individual Retirement Arrangements (IRAs) The successor uses no personal life expectancy calculation.
If the original owner had died after the required beginning date, the successor must continue taking annual distributions during that ten-year window, not wait until year ten to withdraw a lump sum.5Internal Revenue Service. Notice 2024-35, Certain Required Minimum Distributions for 2024 If the original owner died before that date, annual withdrawals aren’t required, only the ten-year emptying deadline.
Penalties for Missing a Required Withdrawal
Withdrawing less than the required amount in a given year triggers a 25% excise tax on the shortfall. SECURE 2.0 cut the rate from the old 50%.
Fixing the mistake quickly cuts the tax further, to 10%. The correction window runs from the date the penalty applies through the earliest of: the date the IRS mails a deficiency notice, the date the IRS formally assesses the tax, or the end of the second tax year after the year the penalty was imposed.
You can also request a full waiver by filing Form 5329 with a written explanation showing that the shortfall was a reasonable error and that you’re correcting it.7Internal Revenue Service. Instructions for Form 5329 (2025) The IRS reviews each request individually and grants waivers fairly often when the beneficiary pulled out the missing amount promptly and explained clearly what happened. Silence and delay make a waiver unlikely.
