Grandchild Inherits an IRA: Rules, the 10-Year Rule, and the EDB Misconception

One of the most common misconceptions in inherited IRA planning: grandchildren assume they qualify for the same treatment as minor children and are surprised to discover the law gives grandchildren no such protection. If you inherited your grandparent's IRA, you are almost certainly subject to the SECURE Act 10-year depletion rule — regardless of your age at the time of inheritance.

Why the "minor child" exception does not apply to grandchildren

The SECURE Act created a category of "Eligible Designated Beneficiaries" (EDBs) who still qualify for the old stretch IRA — annual distributions over their own life expectancy with no 10-year deadline. The five EDB categories are:¹

• Surviving spouse of the IRA owner
• A minor child of the IRA owner (until age 21, then a 10-year window begins)
• An individual who is disabled (per IRC § 72(m)(7))
• An individual who is chronically ill (per IRC § 7702B(c)(2))
• An individual who is not more than 10 years younger than the IRA owner

The critical word in the second category is "child of the IRA owner" — not grandchild. IRC § 401(a)(9)(H)(ii), which defines this exception, specifies the child must be a direct child of the employee (or IRA owner). Grandchildren are legally one generation removed and do not qualify, regardless of their age.¹

This means a 7-year-old grandchild who inherits a grandparent's IRA is in the same position as a 45-year-old grandchild: both face the 10-year rule. Neither gets the stretch IRA that was available before 2020.

The 10-year rule for grandchildren

As a non-EDB grandchild who inherited from a grandparent who died on or after January 1, 2020, you must fully deplete the inherited IRA by December 31 of the calendar year that includes the 10th anniversary of your grandparent's death.¹

The year-10 deadline is absolute. No extensions for hardship, estate complications, or probate delays. Failing to fully deplete triggers a 25% excise tax on the undistributed amount that should have been withdrawn, reduced to 10% if corrected within a two-year correction window under SECURE 2.0.²

Annual RMDs during the 10 years — the post-RBD question

Whether you must take a distribution every single year for the first 9 years — or simply deplete the account however you choose by year 10 — depends on whether your grandparent had started Required Minimum Distributions before they died.

Under the 2024 IRS final regulations (T.D. 10001):³

• Grandparent died BEFORE their Required Beginning Date (RBD): No annual RMDs required during the 10-year window. You can leave the entire balance untouched until year 10, take everything in year 1, or distribute in any pattern you choose — as long as the account is empty by December 31 of year 10.
• Grandparent died ON OR AFTER their RBD: Annual RMDs are required in each of years 1 through 9. You must take at least the calculated minimum in each year; the remaining balance (plus growth) must be fully withdrawn by year 10. Missing a required annual RMD triggers the same 25% excise tax.

The Required Beginning Date (RBD) is April 1 of the year following the year your grandparent reached their required starting age. That age depends on when they were born:⁴

Example: your grandparent was born in 1950, so their RMD starting age was 72. They turned 72 in 2022, making their RBD April 1, 2023. If they died in 2024 — after their RBD — you owe annual RMDs during your 10-year window.

If they died in 2022 before April 1, 2023, they died before their RBD and you have no annual RMD obligation.

How to calculate annual RMDs if grandparent was post-RBD

Annual RMDs for grandchild beneficiaries are calculated using the IRS Single Life Expectancy Table (Pub 590-B, Table I), based on your age in the year following the year of your grandparent's death.⁵

Year-1 formula: December 31 balance of inherited IRA ÷ your Table I life expectancy factor at your age

For each subsequent year, subtract 1.0 from the prior year's factor — do not look up a new factor annually.

Because grandchildren are typically much younger than the children who would have inherited (perhaps 20 to 40 years younger), your Table I factor is generally large — meaning the required annual minimum is relatively small as a percentage of the account balance. However, the balance grows during the window too, and the year-10 lump sum can still be large if you defer discretionary distributions.

Use the Inherited IRA RMD Calculator to project your year-by-year required minimums and see the balance trajectory over 10 years.

The narrow exceptions: disabled and chronically ill grandchildren

Two EDB categories can apply to grandchildren regardless of the generational relationship:

Disabled grandchild (IRC § 72(m)(7)): A grandchild who meets the definition of "disabled" under § 72(m)(7) — unable to engage in any substantial gainful activity due to a medically determinable physical or mental impairment expected to last indefinitely or result in death — qualifies as an EDB. As an EDB, a disabled grandchild can use the stretch IRA: annual distributions over their own single life expectancy, with no 10-year depletion requirement.¹

Chronically ill grandchild (IRC § 7702B(c)(2)): A grandchild who meets the chronically ill standard — unable to perform at least 2 of 6 activities of daily living for at least 90 days, or requiring substantial supervision due to severe cognitive impairment — also qualifies as an EDB.¹

In both cases, the grandchild must establish EDB status with the custodian before the beneficiary determination date (September 30 of the year following the year of the grandparent's death). Documentation of disability or chronic illness will be required. This is not automatic — work with a specialist and the custodian to elect EDB treatment if you believe you qualify.

Planning strategies for grandchild beneficiaries

Grandchildren present a unique planning context. Unlike adult children in their 50s, a grandchild beneficiary is often in their 20s or 30s — early career, potentially in a lower tax bracket now, but on a trajectory toward higher income. That creates different optimization problems.

1. Young grandchildren: match distributions to low-income years

A grandchild who inherits at age 22 and faces a 10-year window depleting by age 32 may be in graduate school, early career, or otherwise earning below their eventual peak income in the first few years of the window. Front-loading distributions during those low-income years can capture unusually low effective tax rates. Once the grandchild reaches higher income years, reduce discretionary distributions to just the mandatory annual RMD floor (if applicable).

2. Minor grandchildren: consider the kiddie tax

If a minor grandchild (under age 19, or under age 24 if a full-time student) takes distributions from a traditional inherited IRA, those distributions are unearned income. The "kiddie tax" rules (IRC § 1(g)) apply unearned income above the annual threshold at the parent's marginal tax rate — not the child's potentially low rate. In 2026, unearned income above approximately $2,500 is taxed at the parent's rate.⁶ A 10-year-old grandchild taking large distributions may owe tax at 32–37% despite having zero earned income of their own, negating the apparent tax benefit. Factor the kiddie tax into any early-year distribution planning.

3. Front-load or back-load: model your income trajectory first

Unlike adult children who often face peak earnings during the 10-year window, grandchildren may have a rising income trajectory — lower now, higher later. This argues for taking more distributions earlier, when the rate is lower, rather than deferring to a year-10 lump sum when the grandchild is more established professionally and in a higher bracket. See the 10-Year Distribution Strategy guide for a full comparison of distribution patterns.

4. Coordinate with other financial planning decisions

Grandchild beneficiaries in their 20s–30s often face competing financial priorities: student loan repayment, home purchase, emergency fund building, Roth IRA contributions of their own. Inherited IRA distributions, while taxable, can provide resources for these goals while also satisfying 10-year depletion obligations. The tax cost of taking distributions in low-income early-career years may be lower than continuing to defer.

5. The year-10 lump sum trap for high earners

If a grandchild defers all discretionary distributions and finds themselves in year 10 with a growing account balance, the lump sum can be destructive. Consider: a $300,000 inherited IRA growing at 6% annually for 10 years becomes approximately $537,000 in year 10. If the grandchild has grown into a $200,000 salary by then, adding $537,000 in one year pushes total income over $737,000 — well into the 37% bracket. The total tax on the inherited IRA lump sum approaches $190,000–$200,000, compared to $90,000–$110,000 if the same amount were distributed in equal annual installments during lower-income years.

6. QCDs if you are 70½ or older at the time of a distribution

A grandchild who inherits in their 60s and is still in the 10-year window at age 70½ or older can make Qualified Charitable Distributions (QCDs) directly from the inherited traditional IRA to a qualified charity. The 2026 QCD limit is $111,000 per taxpayer.⁷ QCDs are excluded from AGI, satisfying part of the distribution obligation without raising MAGI, IRMAA exposure, or Social Security provisional income. This strategy is available only to grandchild beneficiaries old enough to meet the 70½ threshold during the 10-year window.

What if you were a minor grandchild when you inherited?

Unlike a minor child of the IRA owner — who pauses the 10-year clock until age 21 before it begins — a minor grandchild receives no such accommodation. The 10-year window begins the year after the grandparent's death, regardless of the grandchild's age.

A 5-year-old grandchild inheriting in 2026 must have the account fully depleted by December 31, 2036 — when they will be 15 years old. The custodian will typically require a parent or guardian as custodian of the inherited IRA on behalf of the minor. Distributions during minority are subject to the kiddie tax rules described above.

This creates a practical challenge: a guardian managing a significant inherited IRA on behalf of a minor child has 10 years in which the minor will have almost no earned income (potentially leaving distributions taxed at the parent's rate) followed by early adulthood when the window may already be nearly exhausted. Early planning with a specialist is important.

What happened to the "stretch IRA" for grandchildren?

Before the SECURE Act took effect on January 1, 2020, grandchildren who inherited an IRA could use the stretch IRA — annual distributions over their own life expectancy, with no 10-year depletion requirement. A grandchild who inherited at age 25 could stretch distributions over 58+ years, keeping most of the account invested and tax-deferred for decades.

The SECURE Act eliminated this for most non-spouse beneficiaries, including grandchildren. Grandchildren who inherited before January 1, 2020 are still under the old stretch rules and are not subject to the 10-year rule. See the Pre-SECURE Act Inherited IRA guide for those rules.

Your first-year action checklist

1. Confirm the account title. The inherited IRA must be held in an inherited IRA titled in your grandparent's name "for the benefit of" you — for example, "[Grandparent's Name], deceased, IRA FBO [Your Name]." You cannot roll the inherited IRA into your own IRA. See How to Open an Inherited IRA.
2. Determine your grandparent's RBD. Using the birth year table above, determine whether your grandparent died before or after their Required Beginning Date. This determines whether you have annual RMD obligations during the 10-year window.
3. Check for the year-of-death RMD. If your grandparent died after their RBD, ask the custodian whether the full annual RMD for the year of death was taken. The shortfall is owed by December 31 of the year of death.
4. Assess whether you might qualify as a disabled or chronically ill EDB. If you have a qualifying disability or chronic illness, act before September 30 of the year following your grandparent's death to establish EDB status with the custodian. Missing this deadline forfeits the stretch IRA option.
5. Note your 10-year deadline. Mark your calendar with the December 31 depletion deadline using the table above.
6. Project your income trajectory. Grandchildren's income profiles vary enormously — from college students to established professionals. Model where you expect to be in each of the 10 years, identify lower-income years, and plan distribution timing accordingly.
7. Consider the kiddie tax if under 24. If you are a full-time student under age 24, distributions from the traditional inherited IRA will be taxed at your parent's marginal rate, not yours. This reduces the expected tax advantage of early distributions during schooling.

Estate planning implications: naming your own beneficiaries on an inherited IRA

If you (as a grandchild beneficiary) die before exhausting the inherited IRA, what happens to the remaining balance? You can name a successor beneficiary on the inherited IRA. However, your successor beneficiary is not entitled to a new 10-year window. A successor beneficiary to a non-EDB inheritor is subject to the rules described in the Successor Beneficiary guide — typically the remaining years in your 10-year window, not a fresh 10 years from your death. Plan accordingly and ensure the inherited IRA account has a named successor beneficiary.

Dynasty trust as an alternative for grandparents planning ahead

Grandparents who are still alive and want to pass IRA assets to grandchildren without the compressed 10-year tax window sometimes consider naming a dynasty trust as the IRA beneficiary instead of naming the grandchildren directly. If the trust is a properly structured see-through trust meeting the requirements under T.D. 10001, the trust still faces the 10-year rule (because a trust cannot be an EDB for this purpose). However, a trust can control the pace and use of distributions in ways a direct beneficiary designation cannot — including delaying distributions until grandchildren are financially mature, providing asset protection, and coordinating with estate planning across generations.

The trust structure comes with significant complexity and cost: it must be correctly drafted, the 10-year rule still applies, and trust income tax brackets are highly compressed (reaching the top 37% bracket at just $15,650 of taxable income in 2026 for trusts). This is specialist territory. See the Inherited IRA Trust Beneficiary guide for the full analysis.
