Naming a Supplemental Needs Trust as Beneficiary of Retirement Accounts

(Read Naming a Trust as Beneficiary of Retirement Accounts first)

The SECURE Act dramatically reshaped how retirement accounts pass to beneficiaries, replacing the lifetime “stretch” payout with a 10-year clean-out rule for most non-spouse heirs. For families of incapacitated disabled adults, this change created both challenges and opportunities. Although the stretch disappeared for the majority of beneficiaries, disabled and chronically ill individuals were recognized as Eligible Designated Beneficiaries (EDBs). This classification continues to allow inherited retirement accounts to be distributed over life expectancy rather than being forced out within ten years. When these assets are directed to a trust rather than outright to the individual, the trust must qualify as a see-through trust—valid under state law, irrevocable at death, containing identifiable individual beneficiaries, and supported by proper documentation delivered to the plan custodian by October 31 of the year following death of the retirement account holder.

Within this landscape, a special type of see-through trust emerged: the Applicable Multi-Beneficiary Trust, or AMBT. Created under IRC § 401(a)(9)(H)(iv)–(v), an AMBT is intended for situations where at least one current beneficiary of a trust is disabled or chronically ill. Its purpose is straightforward yet essential—allow a trust created for a disabled or chronically ill person to inherit retirement assets and still receive life-expectancy payouts, without forcing “conduit” distributions that would jeopardize eligibility for means-tested benefits like SSI or Medicaid.

There are two practical ways to structure an AMBT. The first is the Type I AMBT, often called the “divide-and-segregate” approach. This model applies when there are multiple beneficiaries, such as siblings, only one of whom is disabled. By December 31 of the year after death, the trust must be separated into subtrusts so that the retirement assets designated for the disabled beneficiary are held solely in that beneficiary’s Special Needs Trust (SNT). Once separated, the disabled beneficiary’s SNT uses life-expectancy required minimum distributions, while the other beneficiaries’ shares default to the SECURE Act’s 10-year rule.

The second structure is the Type II AMBT, designed as a single-beneficiary accumulation trust. As long as the disabled or chronically ill beneficiary is alive, only that beneficiary may receive benefits from the assets traceable to the inherited retirement account. In practice, this structure is usually a third-party SNT drafted as an accumulation trust, allowing the trustee to retain IRA distributions inside the trust without any obligation to distribute them annually to the beneficiary.

Both AMBT types require proof that at least one trust beneficiary is disabled or chronically ill as of the participant’s date of death. A Social Security disability determination generally satisfies disability status, while chronic illness requires a practitioner’s certification. This documentation must be provided to the custodian by October 31 of the year after death.

These developments matter enormously for incapacitated disabled adults. A conduit trust would force all IRA withdrawals out to the beneficiary each year, creating countable income that could instantly disrupt Medicaid and SSI. An AMBT-structured SNT avoids this problem by allowing the trustee to accumulate inherited IRA distributions inside the trust while preserving the life-expectancy stretch. For families with multiple heirs, the Type I AMBT makes it possible to allocate a greater portion of retirement assets to the disabled adult’s SNT to secure preferential payout treatment, while directing non-retirement assets or 10-year-rule retirement shares to other children.

Implementing this planning requires meticulous drafting and administration. A trust receiving retirement assets must satisfy the see-through trust rules: it must be valid under Hawaii law, become irrevocable at death of the retirement account holder, identify individual beneficiaries, and be documented to the custodian by the statutory deadline. Disability or chronic-illness proof must also be submitted timely. The SNT must expressly authorize accumulation of IRA distributions and must limit current benefits exclusively to the disabled or chronically ill individual (for Type II structures) unless the Type I divide-and-segregate approach is used.

When multiple beneficiaries exist, separate subtrusts should be listed directly on the beneficiary designation form so that each can receive its own inherited IRA “account,” allowing independent payout periods. Remainder beneficiaries must also be selected carefully.

Trustees administering an AMBT-structured SNT must track required minimum distributions, maintain disability documentation, and balance the benefits of accumulating income inside the trust with the reality of compressed trust income tax brackets. Distributions should be made in ways that do not interfere with means-tested benefits, such as vendor payments and in-kind supplementation. Hawaii law governs the trust’s validity and SNT administration, and Hawaii income tax applies to retained trust income.

This strategy is especially appropriate when the primary beneficiary is an incapacitated adult who is disabled or chronically ill and depends on or may later need SSI or Medicaid. It also provides continuity of fiduciary management and creditor protection, making it valuable for families concerned about long-term oversight. Large retirement account balances make this planning even more impactful because the life-expectancy stretch spreads taxable income over decades rather than forcing a condensed 10-year withdrawal schedule.

An AMBT provides a federally recognized method for leaving retirement assets to a Special/Supplemental Needs Trust for an incapacitated disabled or chronically ill adult while securing a true life-expectancy stretch and preserving public-benefit eligibility. Success depends on precise drafting—using either the Type I divide-and-segregate model or the Type II single-beneficiary accumulation trust—timely submission of disability documentation, and strict adherence to all see-through trust rules. This planning ensures that families can maximize tax deferral, protect critical benefits, and provide long-term financial security for their most vulnerable loved ones.
