Eligible Designated Beneficiary: Who Still Gets the Inherited IRA Stretch?

The SECURE Act ended the stretch IRA for most people — but five beneficiary categories can still take distributions over a lifetime. Whether you're in one of those categories changes everything about how you plan.

Quick answer: An eligible designated beneficiary (EDB) is a beneficiary who qualifies for the pre-SECURE Act "stretch IRA" treatment — distributions based on life expectancy rather than the 10-year depletion rule. There are exactly five EDB categories under IRC § 401(a)(9)(E)(ii): (1) surviving spouses, (2) minor children of the decedent, (3) disabled individuals, (4) chronically ill individuals, and (5) individuals not more than 10 years younger than the decedent. Everyone else is subject to the 10-year rule. Determining which category applies — and whether you actually qualify — is one of the first things a specialist advisor evaluates.

What changed in 2020 — and what didn't

Before 2020, virtually all individual IRA beneficiaries could "stretch" inherited IRA distributions over their own life expectancy. A 45-year-old inheriting a $1M IRA could spread taxable income over 40+ years, keeping annual distributions small and manageable. This was the stretch IRA, and it was widely used in estate planning.

The SECURE Act, effective January 1, 2020, eliminated this for most non-spouse beneficiaries. Anyone who inherited a traditional IRA after 2019 from a non-spouse is now generally required to deplete the entire account within 10 years of the original owner's death.¹

What the SECURE Act preserved: a narrower category of eligible designated beneficiaries who still qualify for lifetime stretch distributions. If you're in one of these five groups, the 10-year rule doesn't apply to you — and the planning picture looks very different.

The five eligible designated beneficiary categories

1. Surviving spouse

A surviving spouse is always an EDB and receives the most favorable treatment of any beneficiary. As a surviving spouse, you have options no other beneficiary gets:

Spousal rollover: Treat the inherited IRA as your own — it becomes your IRA, subject to your own RMD schedule (not the 10-year rule or life expectancy rules for inherited accounts). See the Spousal Rollover vs Inherited IRA guide for when this is optimal.
Inherited IRA with spousal EDB rules: Keep it as an inherited IRA and use your own life expectancy from the Single Life Expectancy Table. Unlike other EDBs, you can also delay RMDs until the later of December 31 of the year your spouse would have turned 73 (or 75 if born 1960+), or December 31 of the year following the year of death.²
Under-59½ benefit: If you're under 59½ at the time of death, keeping an inherited IRA (rather than rolling over) lets you take distributions penalty-free — something you lose if you roll the account into your own IRA before age 59½.

2. Minor child of the decedent

This category is specifically a minor child of the account owner — not grandchildren, nieces, nephews, or other minors. The IRS defines "minor" as under age 21 for this purpose.³

During minority (under 21), the child uses the stretch IRA based on their life expectancy from the Single Life Expectancy Table. But there's a critical transition rule: once the minor child reaches age 21, the 10-year countdown begins. The stretch doesn't continue for life — it runs only until majority, then the 10-year clock starts.

Minor child example: A 7-year-old inherits a $500,000 IRA from a parent who died in 2024. Using the stretch IRA for 14 years (until age 21 in 2038), distributions are spread over a life expectancy factor of roughly 76 years — producing very small annual minimums. At 21, the 10-year clock starts, requiring full depletion by age 31 (2045). Total timeline: 21 years from the original inheritance, not 10. Annual minimums during the stretch phase are modest; the planning focus shifts to the 10-year window beginning at majority.

Important note: grandchildren, nieces, nephews, or children of siblings are not minor children under this rule unless they were legally adopted by the decedent. Age alone doesn't qualify a beneficiary — the relationship must be direct (biological or adopted child of the IRA owner).

3. Disabled individual

A beneficiary qualifies as disabled if they meet the definition in IRC § 72(m)(7): unable to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or to be of long-continued and indefinite duration.⁴

This is a meaningful threshold. Social Security disability status can be used as evidence but doesn't automatically qualify someone under the IRS definition. The disability must exist at the time of the IRA owner's death.

A disabled EDB uses the stretch IRA based on their own life expectancy. If the disability status ends after the inheritance, the EDB treatment continues — the qualification is determined at the time of death, not monitored going forward.

4. Chronically ill individual

Chronic illness is defined under IRC § 7702B(c)(2): the individual must be certified by a licensed health care practitioner as either (a) unable to perform (without substantial assistance from another person) at least 2 activities of daily living for 90 days or more due to a loss of functional capacity, or (b) requiring substantial supervision to protect them from threats to health or safety due to severe cognitive impairment.⁵

Like the disabled category, qualification is determined at the date of the IRA owner's death. A chronically ill EDB uses the life expectancy stretch, with distributions calculated from the Single Life Expectancy Table.

This category is meaningful for beneficiaries who don't meet the stricter "disabled" standard but have a significant chronic condition that limits daily functioning. Both categories must be documented at the time the inherited account is established.

5. Individual not more than 10 years younger than the decedent

This is the only EDB category based purely on age relationship. If the beneficiary's birth year is within 10 calendar years of the decedent's birth year — even in the older direction — they qualify.¹

Common situations where this applies:

A sibling close in age (a 68-year-old inheriting from a 75-year-old sibling)
A second spouse (often close in age to the decedent)
A long-time domestic partner
A close friend named as IRA beneficiary

There's no family relationship requirement. A non-relative who is 5 years younger than the decedent qualifies. Someone who is older than the decedent also qualifies — the rule says "not more than 10 years younger," so being the same age or older always satisfies it.

When this category applies, the beneficiary uses the life expectancy stretch — but because they're close in age to the decedent, the remaining life expectancy is usually shorter, making the annual distribution minimums higher than they'd be for a younger beneficiary.

What the stretch IRA actually means in numbers

For beneficiaries who qualify as EDBs (other than surviving spouses with rollover option), distributions are calculated using the Single Life Expectancy Table in IRS Publication 590-B, Appendix B, Table I.⁶

The calculation: find your age as of December 31 of the year following the IRA owner's death. Look up the life expectancy factor in the table. Divide the prior December 31 balance by that factor. Each subsequent year, reduce the factor by 1.0 (no recalculation — the factor simply counts down).

Stretch vs 10-year comparison on a $600,000 inherited IRA:

Non-EDB (10-year rule, pre-RBD decedent): No annual minimum required. Could defer until year 10 — a $600K+ lump sum (assuming modest growth) in one tax year. Or take $60K/year for 10 years.
Non-EDB (10-year rule, post-RBD decedent): Annual RMD required each year. At age 55, first-year RMD ≈ $19,000. But account must still be depleted by year 10 — so years 8-10 require large additional distributions beyond the annual minimum.
EDB (stretch, age 55): Life expectancy factor at 55 ≈ 31.6. First-year distribution: $600,000 ÷ 31.6 = $18,987. Year 2: balance ÷ 30.6. The distribution grows slowly as the factor decreases and (ideally) the balance grows — but it's spread over a lifetime, never requiring a year-10 spike.

The lifetime tax impact difference between 10 years and 31+ years of distributions can reach six figures for larger accounts, even before counting investment compounding.

If you're NOT an EDB: the 10-year rule applies

Most adult children, grandchildren, siblings not close in age, nieces and nephews, friends, and other beneficiaries who don't fit the five EDB categories are subject to the 10-year rule. The entire inherited IRA must be depleted by December 31 of the 10th year following the year of death.

Whether you also owe annual distributions within that window depends on when the original owner died relative to their Required Beginning Date — the subject of the Inherited IRA RMD Rules guide. The short version: if the decedent had already started RMDs (died on or after their RBD), you owe annual minimums plus the 10-year depletion. If they died before their RBD, you have full flexibility within the window.

Even under the 10-year rule, the timing of distributions within the window is yours to manage — and the difference between an optimized withdrawal schedule and equal annual payments can be substantial. See the Roth Conversion Coordinator and 10-Year Withdrawal Optimizer.

Why EDB status determination matters immediately

When you establish an inherited IRA with a custodian (Fidelity, Schwab, Vanguard, etc.), you typically have to designate your beneficiary type. The custodian may or may not ask; if you self-certify incorrectly, you could end up taking distributions on the wrong schedule. Too few distributions in early years means a 25% excise tax on amounts you should have taken. Too many distributions means unnecessary taxable income you can't undo.

For the disabled and chronically ill categories, the IRS may require documentation at the custodian. For the "not more than 10 years younger" category, the age relationship needs to be verifiable from the death certificate and beneficiary's ID. For minor children, the switch to the 10-year rule at age 21 needs to be tracked — custodians don't always flag it proactively.

Trust beneficiaries and EDB rules

If a trust is the named IRA beneficiary, the EDB analysis looks through the trust to the underlying beneficiaries — but only if the trust qualifies as a "see-through" trust (also called a conduit or accumulation trust meeting IRS requirements). If the trust qualifies:

The EDB categories are evaluated against the trust's beneficiaries.
If the oldest beneficiary of the trust is not an EDB, the 10-year rule applies to the entire trust.
If the trust is specifically designed for a disabled or chronically ill beneficiary and meets the special accumulation trust rules, it can qualify for the EDB stretch.

Trust-as-beneficiary situations are among the most complex in inherited IRA planning. An improperly drafted trust can strip an otherwise-qualifying EDB of their stretch treatment. This is an area where advisor and estate attorney coordination is almost always necessary.

EDB status and inherited Roth IRAs

EDB rules apply to inherited Roth IRAs as well. A surviving spouse EDB of an inherited Roth IRA can roll it over into their own Roth IRA — fully preserving the tax-free compounding with no RMDs required.

Other EDBs with inherited Roth IRAs can use the stretch — but since there are no annual RMDs for Roth IRAs (the original owner had no RBD), the annual distribution rules from T.D. 10001 don't apply. Annual distributions are optional; what matters is that you ultimately distribute based on your life expectancy. In practice, most EDB Roth inheritors defer as long as possible — letting tax-free compounding run while taking only what the table requires.

Non-EDB beneficiaries of inherited Roth IRAs face the 10-year rule, but with a key advantage: they can defer all distributions until year 10 (no annual RMDs), making the inherited Roth IRA more flexible than an inherited traditional IRA in the non-EDB context. See the Inherited Roth IRA guide.

The advisor's role in EDB situations

If you're an EDB, the planning stakes are high — in both directions. Qualifying for the stretch is valuable, but the optimal strategy still requires multi-year modeling:

Disability and chronic illness categories: Distributions must still be taken (at least the annual minimum). Coordinating distributions with needs-based government benefits (Medicaid, SSI) is critical — an inherited IRA can affect benefit eligibility in ways that require a special needs trust or careful planning around the timing and use of distributions.
Minor child category: The stretch-to-10-year transition at age 21 needs to be actively managed. The advisor should model distributions during the stretch phase and plan for the 10-year window that follows, often during the child's peak earning years — when additional taxable income is most expensive.
Close-in-age (not-10-years-younger) category: Because life expectancy is shorter, annual minimums grow relatively quickly. Coordinating these with the beneficiary's own retirement distributions, Roth conversions, and Social Security timing is real planning work.
Surviving spouse: The rollover vs inherited IRA decision has a five- to seven-figure lifetime impact for many couples. It's one of the first decisions to model.
