Look-through trust rules set the payout clock for inherited IRAs

A trust is not an individual. That is the starting point for inherited IRAs held in trusts, and the reason so many beneficiaries are surprised by the payout clock. The SECURE Act, the SECURE 2.0 Act, and subsequent regulations layered new distribution rules onto retirement accounts, with trusts at the center of the complexity.

If a trust qualifies as a look-through, or see-through, trust, the individual beneficiaries behind it can qualify as non-eligible designated beneficiaries (NEDBs) or eligible designated beneficiaries (EDBs). That lets the trust use the 10-year payout, or a lifetime stretch if an eligible designated beneficiary is involved. A trust that fails the test faces the five-year rule, the strictest deadline in the distribution code. The post-SECURE world divides beneficiaries into those who get a 10-year window and those who can stretch over life expectancy; the trust's place in either camp depends on the look-through test.

Sarah Brenner, director of retirement education at IRAHelp, lays out the conditions in a post on the site. All four have to be satisfied.

First, the trust must be valid under state law. Second, it must be irrevocable, or become irrevocable at the IRA owner's death. Third, the beneficiaries have to be identifiable: a named person or a defined class such as "my grandchildren." A phrase like "my friends" does not pass. The identifiability requirement is the one that trips up many trusts; a definable class like "my descendants" survives, a vague label does not.

The fourth condition applies only to employer plans. There, the plan administrator can require the trustee to hand over a list of beneficiaries with the conditions on their entitlement, or a copy of the trust document, by October 31 of the year after the death. For IRAs, no such documentation is required. That asymmetry matters when an employer-plan account rolls into an IRA. Because no custodian will flag a defective trust, the advisor alone is left to find the problem. The documentation requirement that protects the employer-plan beneficiary has no IRA counterpart.

The asymmetry is a trap for the unwary. An advisor who handled an employer-plan rollover into an IRA may not realize the trustee's documentation obligation disappears with the rollover. The trust document that satisfied the plan administrator is not reviewed by the IRA custodian, so the advisor must perform that review solo.

Even a trust that satisfies all four conditions can hit the five-year clock if any beneficiary is not a living person. A charity is the usual example. Brenner puts it carefully: there may still be no NEDB or EDB even for a qualifying trust. With no NEDB or EDB to anchor the payout, the trust falls back to the five-year deadline.

For an advisor reviewing a client's inherited IRA, the test happens at the document level. The IRA custodian does not ask for trust documents, so the responsibility falls on the advisor to request the trust, read it, and check the beneficiary list. That means not only confirming the trust is valid and irrevocable but also scanning who else is listed. A trust that names a grandchild and a foundation passes the look-through conditions but may still face the five-year payout because the foundation is not an individual.

The difference between a ten-year clock and a five-year clock is not a matter of convenience. It changes the distribution plan for the trust and the tax bill for its beneficiaries. A trustee facing the five-year rule has to move the entire account out of the trust in half the time, which can force asset sales in an unfavorable market. For a trust holding a seven-figure IRA, the stakes are real.

Brenner also notes that only individuals named on the IRA beneficiary form, or named through the custodial document when no beneficiary is named, can qualify as NEDBs or EDBs. A trust by itself is not an individual. The look-through rules connect the trust to particular people, and the connection holds only while the beneficiary list is clean.

The advisor's job is not to redraft the trust but to understand what it says. Coordination with estate counsel becomes the natural next step when the trust language is ambiguous. The look-through test is a parsing exercise, and the outcome determines the entire inherited IRA strategy. The trust document, not the beneficiary form, is where the payout schedule is won or lost.

For a trust drafted before the SECURE Act, the gap between intent and outcome often shows up in the payout clock. Old documents may not say how the trustee should handle the 10-year window, leaving the trustee to guess. The look-through review has to be repeated whenever the trust or the beneficiary form changes. A beneficiary change or an amended trust rewrites the analysis from scratch.

The order matters. The look-through determination comes first; the distribution schedule comes second. Advisors who review trusts after a client's death are already short on time. The October 31 deadline for employer-plan documentation, when it applies, is firm. For an IRA-owned trust, no filing date triggers the analysis; only the advisor's diligence does. That makes the trust document itself the deadline.
