Quick Read

The SECURE Act of 2019 forces most non-spouse beneficiaries to drain inherited IRAs within 10 years, but those within 10 years of the decedent's age qualify for life expectancy withdrawals instead.
A $200,000 inherited IRA forces a 48-year-old into peak-earning-year tax stacking, while a 61-year-old sibling inheriting the same account controls her marginal rate by spreading withdrawals over decades.
A Roth conversion during the account owner's lifetime makes inherited withdrawals tax-free, neutralizing the bracket problem for beneficiaries stuck under the 10-year rule.

Two siblings inherit identical $200,000 traditional IRAs from the same older sister, who died at 65. The 61-year-old inheriting sister can spread withdrawals across her remaining life expectancy, but the 48-year-old brother must drain the entire account by the end of the tenth year after their sister's death. The decedent, dollar amount, and account type are identical, yet the tax outcomes differ completely. The reason is a single provision buried in the Eligible Designated Beneficiary rules that almost no account owner knows exists.

Two Siblings, One IRA, Two Deadlines

The SECURE Act of 2019 ended the old stretch IRA for most non-spouse beneficiaries. Anyone inheriting a retirement account from an owner who died after December 31, 2019 generally has to empty it within 10 years. That is the default. The exceptions are narrow and collectively called Eligible Designated Beneficiaries.

Five categories qualify: a surviving spouse, a minor child of the account owner, a disabled individual, a chronically ill individual, and any individual not more than 10 years younger than the decedent. That last one is the sibling rule. The test compares each beneficiary's age to the person who died, not to any fixed cutoff, so the same person can be an eligible beneficiary of one sibling and not of another. The deceased sister was 65. Her 61-year-old sister is four years younger and clears the bar. Her 48-year-old brother is 17 years younger and does not.

Why One Path Stretches and the Other Compresses

Congress wrote the 10-year rule to accelerate tax collection on inherited retirement accounts. The old stretch let a young beneficiary draw tiny required distributions across decades while the balance kept compounding tax-deferred. An eligible beneficiary who uses the life expectancy method takes the first distribution in the year after the owner's death, using a divisor from the IRS Single Life Table based on her age that year. In each subsequent year, the divisor drops by one. The account can last decades.

For a beneficiary subject to the 10-year rule, whether annual withdrawals are also required during those 10 years depends on whether the original owner had already started their own required minimum distributions. If the owner died before their required beginning date, the beneficiary can wait and take the whole balance on the final day of year 10. If the owner had already begun RMDs, annual distributions must continue during the 10-year window, and the balance must still be zero by the deadline. The IRS finalized this interpretation, with the first enforcement year set for 2025.

Tax Bill Hidden Inside the 10-Year Window

Every dollar coming out of a traditional inherited IRA is ordinary income. The 48-year-old brother is in his peak earning years. Draining a $200,000 balance over a decade adds tens of thousands of extra taxable dollars to his annual income, and market growth inside the account makes later withdrawals larger.

That income can push him into a higher federal bracket than the original owner ever paid and can affect income-based thresholds like IRMAA surcharges when he approaches Medicare age. The 61-year-old sister, spreading withdrawals across her own life expectancy and likely retiring during the payout period, controls her marginal rate. The brother does not.

Edge Cases Every Account Owner Should Know

A minor child of the account owner gets life expectancy treatment only until the age of majority, then the 10-year clock starts. A disabled or chronically ill beneficiary keeps the stretch for life. An eligible beneficiary who dies partway through her stretch hands the remainder to a successor beneficiary who must finish the balance within 10 years of that second death. The penalty for missing a required distribution was 50% of the shortfall and is now 25%, reduced to 10% if corrected within a two-year window under SECURE 2.0. A non-spouse beneficiary cannot roll an inherited account into their own IRA under any circumstance.

What to Check on Your Beneficiary Form This Month

Beneficiary designations override wills, and most people fill in the form once and never revisit it. A Roth conversion during the owner's lifetime does not remove the 10-year rule for a non-eligible beneficiary, but it makes the eventual withdrawals generally tax-free, which neutralizes the bracket problem. Naming a trust as beneficiary triggers a separate set of see-through rules that genuinely require a specialist.

A review of the beneficiary designations on file with the IRA custodian can identify listed heirs who are more than 10 years younger than the account owner. Those beneficiaries will inherit under the 10-year rule, with the resulting tax bill landing during their working years. The account owner can fix this during their lifetime, but cannot change it afterward.
