IRS Rules on Trustee-to-Trustee Transfers of Inherited IRAs to Estate Beneficiaries

IRS Greenlights Tax-Free Splitting of Inherited IRAs for Estate Beneficiaries

The IRS has issued a private letter ruling (PLR-102620-26) confirming that estate beneficiaries may split inherited IRAs into separate accounts via trustee-to-trustee transfers without triggering taxable distributions or rollovers. The ruling addresses a longstanding ambiguity under Internal Revenue Code § 408(d)(3), which governs IRA distributions and rollovers, and provides clarity for estates inheriting IRAs where no designated beneficiaries exist. The IRS’s favorable response hinges on the application of Revenue Ruling 78-406, which established that direct trustee-to-trustee transfers are not taxable events under § 408. This ruling is particularly significant for estates that inherit IRAs through default succession (e.g., via a will) rather than through designated beneficiaries, as it allows for the division of IRA assets into separate accounts for individual beneficiaries without immediate tax consequences.

The Estate’s Dilemma: Splitting IRAs Without Triggering Taxable Distributions

The decedent died on Date 2, leaving two individual retirement accounts (IRAs)—a traditional IRA (IRA X) and a Roth IRA (IRA Y)—with no designated beneficiaries. Under IRC § 408(a), which defines IRAs as trust or custodial accounts created for an individual’s benefit, the decedent’s estate (Estate E) automatically became the beneficiary of both accounts due to the absence of named successors.

The decedent’s Last Will and Testament, executed on Date 1, directed that IRA X and IRA Y be divided equally between Taxpayer A and Taxpayer B (Beneficiaries). On Date 3, a State S court appointed Taxpayer A as administrator of Estate E. Faced with the task of distributing the IRA assets in accordance with the will, the estate administrator proposed a solution: executing trustee-to-trustee transfers to split the balances of IRA X and IRA Y into two separate IRAs for each beneficiary.

Under the proposed plan, the original IRAs—retitled as “IRA of Decedent f/b/o Estate E” after death—would be restructured into four new accounts. Each transferee IRA would be titled “Decedent (Deceased) IRA f/b/o Beneficiary as beneficiary of Estate E,” reflecting the decedent’s estate as the source of the funds and the individual beneficiary as the new account holder. The estate administrator sought to avoid any direct distribution to the beneficiaries, which could trigger immediate taxable events under IRC § 408(d)(1), which taxes IRA distributions as ordinary income unless an exception applies. Instead, the administrator aimed to preserve the tax-deferred status of the inherited assets through direct transfers between trustees.

IRS Approves Tax-Free Transfers, Citing Revenue Ruling 78-406

The IRS granted the estate administrator’s two requests, confirming that the trustee-to-trustee transfers of inherited IRA interests would not trigger taxable distributions. First, the IRS ruled that the transfers from IRA X and IRA Y to the separate transferee IRAs would not constitute taxable distributions under § 408(d)(1), which taxes IRA distributions as ordinary income unless an exception applies. Second, the IRS held that the transfers would not qualify as rollovers under § 408(d)(3), which defines rollovers as distributions followed by redeposits within 60 days.

The IRS grounded its analysis in Revenue Ruling 78-406, which established that direct trustee-to-trustee transfers do not constitute distributions or rollovers. The ruling clarified that such transfers avoid the 60-day rollover requirement and the one-per-year rollover limit. The IRS emphasized the critical role of IRA titling, noting that the transferee IRAs would be established as “Decedent (Deceased) IRA f/b/o Beneficiary as beneficiary of Estate E,” preserving the decedent’s identity while reflecting the beneficiary’s interest. This titling structure ensured the transfers remained within the scope of Revenue Ruling 78-406, as the accounts were not retitled to the beneficiaries’ names but instead maintained the decedent’s ownership designation with the beneficiary’s interest explicitly noted.

What This Ruling Means for Estates and IRA Beneficiaries

This Private Letter Ruling (PLR-102620-26) provides targeted relief for estates inheriting IRAs without designated beneficiaries, but its non-precedential nature limits its broader applicability. Section 6110(k)(3) of the Internal Revenue Code explicitly states that PLRs "may not be used or cited as precedent," meaning other taxpayers cannot rely on this ruling to justify similar tax-free splits of inherited IRAs. The IRS retains discretion to revoke or modify rulings retroactively if facts differ materially from those represented, as outlined in Rev. Proc. 2026-1, § 11.05. Taxpayers should consult their advisors before relying on this ruling, as the IRS has not addressed other critical inherited IRA rules, including required minimum distributions (RMDs) under § 408(a)(6) and the SECURE Act’s 10-year distribution rule.

The ruling hinges on precise IRA titling to preserve tax-free treatment. The transferee IRAs were structured as “Decedent (Deceased) IRA f/b/o Beneficiary as beneficiary of Estate E,” maintaining the decedent’s identity while explicitly noting the beneficiary’s interest. This titling ensured the transfers qualified under Revenue Ruling 78-406, which permits tax-free trustee-to-trustee transfers. However, if the facts had varied—such as if the estate included designated beneficiaries or if the IRAs were retitled to the beneficiaries’ names—the IRS could have disallowed the tax-free treatment. For example, if the estate had named individuals as direct IRA beneficiaries, the transfers might have triggered taxable distributions under § 408(d)(1), as inherited IRAs cannot be rolled over by non-spouse beneficiaries under § 408(d)(3)(C).

The broader context of inherited IRA rules underscores the risks of non-compliance. Estates inheriting IRAs without designated beneficiaries must navigate § 408’s strict requirements, including the prohibition on indirect rollovers for non-spouse beneficiaries. The SECURE Act’s 10-year distribution rule further complicates planning, as most non-spouse beneficiaries must fully distribute inherited IRAs by the end of the 10th year following the decedent’s death, regardless of RMDs. While this PLR does not address RMDs, estates should anticipate potential IRS scrutiny of distribution timing and titling to avoid unintended tax consequences. The IRS’s emphasis on Revenue Ruling 78-406 suggests that trustee-to-trustee transfers remain the safest method for splitting inherited IRAs, but only if the titling and factual circumstances align precisely with the ruling’s conditions.
