Special Needs Trust: Leaving Assets for a Disabled Beneficiary Without Losing Their Benefits

If you have a child, grandchild, or other family member with a serious disability, the standard estate planning approach — leave them money outright — can be the worst thing you do for them. A $500,000 inheritance can wipe out Medicaid and SSI coverage that was paying for $15,000–$20,000/month in institutional care. A properly drafted special needs trust avoids that trap, preserves government benefits, and puts you in control of how assets are used for the beneficiary's lifetime.

The outright inheritance problem

Medicaid and Supplemental Security Income (SSI) are means-tested programs with strict resource limits. For SSI, a disabled individual can own no more than $2,000 in countable resources (not counting a home, one vehicle, and a few other exclusions).² Medicaid rules in most states are similar.

When a disabled person receives an outright inheritance — through a will, a beneficiary designation, or any direct transfer — that inheritance counts as a resource. A $200,000 inheritance puts them $198,000 over the SSI limit, triggering immediate suspension of benefits. They must spend down the inheritance paying for their own care before Medicaid resumes. For someone in institutional care at $15,000/month, that's a forced $200,000 payment to the care facility. Then benefits restart — but only after the money is gone.

This is what a special needs trust prevents.

How a third-party special needs trust works

A third-party special needs trust is funded with your assets — not the disabled person's own assets. Because the assets were never theirs, they don't count as the beneficiary's resource for SSI and Medicaid purposes, as long as the trust is structured correctly:

• Discretionary distribution standard. The trustee must have complete discretion over distributions. If the beneficiary has a legal right to demand funds, the trust is treated as a resource. "The trustee shall pay for the beneficiary's supplemental needs as the trustee deems appropriate" — acceptable. "The trustee shall pay $2,000/month" — not acceptable (creates an enforceable right).
• Supplemental, not primary, support. The trust purpose must be to supplement government benefits, not replace them. Language that makes the trust the "first resort" for food and shelter can cause Medicaid to count the trust as available.
• No Medicaid payback required. Unlike a first-party SNT (see below), a third-party SNT funded with your assets does not need to reimburse the state for Medicaid expenses at the beneficiary's death. The trust corpus can pass to other beneficiaries — your other children, grandchildren, or a charity.

The trust is an irrevocable entity (you give up control of the assets) but you control the terms: who the trustee is, what the trust can pay for, and who receives any remaining assets after the disabled beneficiary dies.

Third-party vs first-party: the critical distinction

What the trust can — and can't — pay for

The trustee has broad discretion over supplemental needs distributions, but the distinction between "supplemental" and "basic support" matters for benefit preservation:

Generally safe to pay for (supplemental needs):

• Medical and dental expenses not covered by Medicaid
• Education, job training, vocational therapy
• Technology (computer, tablet, phone, accessibility devices)
• Recreation, entertainment, travel, vacation
• Transportation beyond what Medicaid covers
• Personal care attendants (for services Medicaid doesn't cover)
• Companion services, household maintenance
• Legal fees, financial planning, trust administration

Requires caution (in-kind support and maintenance):

• Food and shelter paid directly to the beneficiary are "in-kind support and maintenance" (ISM) for SSI purposes. If the trust pays rent or provides groceries directly, the SSI check is reduced by the lesser of one-third the Federal Benefit Rate (FBR) or the actual value of support received. It doesn't terminate benefits — just reduces the SSI check. For many beneficiaries in institutional care, this is irrelevant; for community-based living situations, it matters.
• The trustee should pay for housing indirectly (rent to a landlord, mortgage to a bank, not cash to the beneficiary) and consider whether the ISM reduction is worth the distribution.

ABLE accounts: the companion tool

ABLE accounts (IRC § 529A) are tax-advantaged savings accounts for individuals with disabilities.⁴ They're not a substitute for an SNT, but they work well alongside one.

Key 2026 ABLE rules:

• Eligibility: disability onset before age 46 (expanded from age 26 effective January 1, 2026, by the ABLE Age Adjustment Act).¹
• Annual contribution limit: $19,000 from all contributors combined (equals the 2026 annual gift tax exclusion per IRC § 529A(b)(2)(B), IRS Rev. Proc. 2025-32).⁵ Working beneficiaries who don't participate in an employer retirement plan may contribute an additional amount up to their gross employment income.
• SSI exception: ABLE account balances up to $100,000 are excluded from the SSI resource limit. Above $100,000, SSI is suspended — but not terminated — until the balance drops below $100,000.
• Tax treatment: contributions are after-tax; growth and qualified distributions (for disability expenses) are tax-free, similar to a Roth account.

SNT vs ABLE: use them together. The SNT holds the family's primary wealth transfer — hundreds of thousands to millions of dollars — for lifetime needs. The ABLE account is for day-to-day disability expenses where the beneficiary or a third party wants direct account access. ABLE accounts can be opened and managed by the beneficiary themselves; an SNT requires trustee approval for every distribution. Together, they cover both the large structural wealth transfer and the day-to-day flexibility.

Tax treatment of an SNT

A third-party special needs trust is a separate tax entity. It files Form 1041 annually and faces the notorious trust compressed tax brackets: in 2026, the 20% capital gains rate applies to estates and trusts with income above just $15,900 of net investment income (vs. $583,750+ for single individuals), and the top 37% ordinary income rate kicks in at a similarly low threshold.⁵

Two strategies for managing this:

1. Distribute income to the beneficiary. Trust distributions of income are taxable to the beneficiary, not the trust. If the beneficiary has little other income (common with disabled individuals), taxing trust income at their rate — which may be 0% or 10% — dramatically reduces the total tax bill. Caveat: distributions must be for supplemental needs; large cash distributions create ISM issues as noted above. Work with the trustee and a CPA to optimize.

2. Elect Qualified Disability Trust (QDT) status. Under IRC § 642(b)(2)(C), a trust qualifies as a "qualified disability trust" if all beneficiaries are SSA-certified disabled for some portion of the year.³ A QDT receives a much larger income tax exemption than the standard $100/$300 trust exemption — equal to an individual's personal exemption equivalent (adjusted annually for inflation). This meaningfully reduces taxable income retained in the trust without requiring distributions. The trustee makes this election annually on Form 1041.

IRAs, retirement accounts, and SECURE 2.0

Leaving a retirement account (IRA, 401(k)) to a disabled beneficiary has important nuances under SECURE 2.0.⁶

Disabled persons are Eligible Designated Beneficiaries (EDBs). Under IRC § 401(a)(9)(E)(ii)(III), a beneficiary who is disabled (meeting the IRC § 72(m)(7) standard) qualifies as an EDB and may use the life expectancy stretch rule — taking required minimum distributions over their lifetime rather than being forced to empty the account within 10 years. For a young disabled beneficiary, this extends tax-deferred growth by decades.

Naming an SNT as IRA beneficiary is complex. If the IRA names the SNT as beneficiary rather than the disabled person directly, the EDB stretch must flow through the trust. The SNT must qualify as a "conduit trust" or "accumulation trust" with proper see-through rules, and the trustee must be able to demonstrate that the disabled beneficiary is the sole lifetime beneficiary. Poorly drafted trusts can lose the EDB stretch and trigger the 10-year liquidation rule — with all the compressed income from liquidating a large IRA hitting trust compressed tax brackets.

Consider two structures:

• IRA directly to disabled person as EDB: preserves the stretch, but the inherited IRA distributions go directly to the beneficiary and may count as income for SSI means-testing. Consult a special needs attorney before this approach.
• IRA to SNT as accumulation trust: requires careful drafting to preserve EDB status but keeps assets within the trust framework. A trust-and-estates attorney with both SECURE 2.0 and special needs expertise is essential here.

A simpler alternative: convert traditional IRAs to Roth IRAs during your lifetime (paying the conversion tax while you're in a lower bracket), then name the SNT as Roth IRA beneficiary. Roth inherited IRAs distributed to a trust still face the 10-year rule (for non-EDB trusts), but distributions are tax-free — which eliminates most of the damage from accelerated withdrawal. See our IRA estate planning guide for full SECURE 2.0 mechanics.

GST planning for long-lived SNTs

An SNT for a young disabled beneficiary can easily last 40–60 years — spanning multiple generations. If the trust passes assets to the beneficiary's descendants (or to grandchildren of the grantor) at the beneficiary's death, those distributions may be subject to the generation-skipping transfer (GST) tax.

The solution is to allocate GST exemption when funding the SNT. Each individual has $15,000,000 in GST exemption for 2026 (post-OBBBA, IRS Rev. Proc. 2025-32).⁵ Allocating GST exemption to the SNT (inclusion ratio = 0) means trust assets and all future appreciation pass free of GST tax to all subsequent generations — identical to the dynasty trust structure for non-disabled beneficiaries. See our GST tax guide for the mechanics of inclusion ratios and exemption allocation.

Important: automatic GST allocation rules under IRC § 2632 do not necessarily allocate exemption to an SNT. The grantor should affirmatively elect allocation on Form 709 (gift tax return) when funding the trust.

Worked example: $18M estate, one disabled child

A married couple has $18M in net worth: $12M in a diversified investment portfolio, $4M in real estate, $2M in IRAs. They have two adult children — one is non-disabled, one has been severely disabled since childhood and receives SSI and Medicaid-funded institutional care ($14,000/month).

Without an SNT: They split the estate equally — $9M to each child. The disabled child's $9M inheritance immediately disqualifies them from SSI and Medicaid. The care facility bills $14,000/month privately. At that rate, the $9M lasts about 53 years — but the child is already 45 and the care costs will increase. Worse: the non-disabled sibling now bears emotional responsibility for managing the disabled sibling's care and finances.

With an SNT: The will and all beneficiary designations route the disabled child's share into a third-party special needs trust funded with $9M. The trustee (a professional trust company) manages distributions for supplemental needs — better technology, private-pay companions not covered by Medicaid, educational and recreational programs. Medicaid and SSI continue, covering the $14,000/month institutional care. At the disabled child's death, the trust corpus (which may have grown to $25M+ at 7% over 30 years) passes to the couple's grandchildren — with GST exemption allocated at funding, no estate or GST tax at that generational transfer.

The $9M legacy doubles or triples in value instead of being consumed by institutional care costs.

Trustee selection

SNT trustees have a highly specialized job: managing investments, making discretionary distribution decisions that preserve government benefit eligibility, filing Form 1041 annually, and adapting to changes in SSI/Medicaid rules that will certainly occur over a 40-year trust term.

Most attorneys recommend a professional or corporate trustee as at least the co-trustee for SNTs. A family member who doesn't understand that paying rent directly to a landlord reduces SSI but doesn't terminate it — or who makes a distribution that the Social Security Administration classifies as an overpayment — can inadvertently harm the beneficiary.

A common structure: a trust company serves as corporate trustee (managing investments, tax filings, benefit compliance), with a family member appointed as "care advocate" or "trust protector" who can direct the corporate trustee on personal care matters and replace trustees if needed. This preserves the family's involvement without putting the legal liability on a family member unfamiliar with SSI rules.

5 common mistakes

1. Naming the disabled person directly in beneficiary designations. If your will, IRA, life insurance, or bank accounts name the disabled child outright, those assets bypass the SNT and go directly to the beneficiary — triggering the same benefit-disqualification problem the SNT was designed to prevent. Every beneficiary designation on every account must be updated.
2. Leaving assets outright to a sibling to "take care of" the disabled person. The sibling's assets can be lost in divorce, seized in a lawsuit, or simply spent. The sibling may predecease the disabled person. A well-funded SNT is protected from all of these; an informal arrangement with a sibling is not.
3. Drafting the trust as a "support trust" rather than a "supplemental needs trust." Language that directs the trustee to pay for the beneficiary's "health, education, maintenance, and support" is a Medicaid trigger — it makes the trust a primary support mechanism that Medicaid agencies can count as available. The trust language must clearly state supplemental needs only.
4. Forgetting GST exemption allocation. A 60-year-old grantor who funds a $3M SNT for a 35-year-old disabled child has created a multi-generational trust. Without GST exemption allocated on Form 709, distributions to grandchildren may trigger 40% GST tax. Allocate exemption when funding — not years later when it may be too late to correct.
5. Naming a family member as sole trustee without professional co-trustee. Medicaid rules change, SSI rules change, and a non-specialist trustee making a well-intentioned distribution can inadvertently disqualify the beneficiary. The trustee liability exposure is real. Use a professional trustee at least as co-trustee on any SNT expected to hold significant assets for a long term.
