Estate Planning: Should you name a living trust as beneficiary of your retirement accounts?

Feb 4, 2026 | Estate Planning

Naming a living trust as beneficiary of a retirement account can solve real problems, provide creditor protection, control over timing of distributions and coordinating beneficiary rules with other assets, but it also introduces tax and administrative complexity.

Here’s what to know under California and federal rules, how the IRS “look-through” (see-through) treatment works and what actually happens when you die.

Federal tax and distribution rules. Since the SECURE Act (effective 2020), most non-spousal beneficiaries must withdraw inherited retirement accounts within 10 years of the owner’s death (the “10-year rule”), subject to exceptions for certain “eligible designated beneficiaries” (spouse, minor child, disabled/chronic illness or someone within 10 years of the owner’s age). That rule applies whether the IRA is paid outright to a person or to a trust, unless the trust qualifies to be treated as a “designated beneficiary.”

The IRS “look-through” (see-through) trust concept. A trust is an entity, not an individual, so the IRS will normally treat it as a non-designated beneficiary (which may shorten payout options). To avoid that, a trust must meet the “see-through” requirements so the IRS can look through to the trust’s individual beneficiaries. Commonly quoted requirements: (i) the trust must be valid under state law; (ii) irrevocable (or become irrevocable at death); (iii) have identifiable individual beneficiaries; and (iv) satisfy the custodian’s documentation rules. If those boxes are checked, the trust’s beneficiaries, not the trust itself, determine what distribution rules apply (and whether a life-expectancy payout or the 10-year rule applies).

Conduit vs. accumulation trusts, practical difference. A conduit trust requires the trustee to pass distributions immediately to the trust beneficiaries (so beneficiaries are taxed on Required Minimum Distributions (“RMDs”). An accumulation trust lets the trustee keep distributions inside the trust, which may cause higher trust tax rates and can alter which payout period applies. Choice matters, as conduit trusts often preserve beneficiary tax timing. Accumulation trusts can protect assets but may accelerate taxes.

California and spousal ownership issues. California’s community-property rules and federal ERISA spousal-consent protections mean that, for employer plans, a spouse’s written consent is often required before naming a non-spouse beneficiary. For IRAs the legal requirement is different, but community property claims can still complicate things. Because state law can affect whether an account is “community” or separate property, spouse rights and consent are practical issues to address.

What happens when you die. The custodian is given the death certificate and beneficiary designation. If a trust is beneficiary, the trustee will provide required trust documentation. The account is retitled or paid per plan rules, and distributions are made according to the trust terms and IRS rules (see-through treatment permitting life-expectancy or 10-year timing depending on circumstances). Trustees must coordinate with custodians and tax advisors to avoid unwanted acceleration of taxable events.

Bottom line. A trust can be a powerful tool for retirement assets, but only if it’s drafted and administered to satisfy IRS and plan requirements. Because small drafting choices (irrevocability, beneficiary identification, conduit language) change tax outcomes, consult your estate-planning attorney and the account custodian before naming a trust.
