A grandmother wants to leave her grandson $75,000. He is twenty-two, has autism, and lives semi-independently. His life is stitched together by two things she does not fully understand: a monthly SSI check that pays for the essentials, and Medicaid, which covers the therapists, day program, and case manager who have known him since he was small. She writes his name into her will and puts it away. If nothing else changes, that act of love could end his benefits overnight.
Special needs trusts exist for this exact moment — when a family wants to give something and the government's means-tested rules would take everything else away. This article walks through what a special needs trust is, the three main types, what they can and cannot pay for, how to fund one, and why working with a specialized attorney is not optional here. It is educational only. It is not legal advice.
The problem a special needs trust solves
Supplemental Security Income (SSI) and Medicaid are the two programs that keep millions of Americans with disabilities housed, fed, and medically cared for. Both are means-tested: eligibility depends not just on disability but on how few assets a person owns. The countable resource limit for SSI is $2,000 for an individual and $3,000 for a couple, according to the Social Security Administration. That limit has not been adjusted for inflation since 1989, as documented by the Congressional Research Service. In 1989 the ceiling was tight; nearly four decades later it is a trap door.
Cross the line by a single dollar and a person can lose SSI, and in many states lose Medicaid along with it. A well-meaning inheritance, a legal settlement, a birthday gift, or a life insurance payout naming the person directly — any of these can be catastrophic. Benefits stop. Therapists and case managers stop. Coverage for the community-based services that let the person live outside an institution often stops with them.
A properly drafted special needs trust — sometimes called a supplemental needs trust — holds assets for the person with a disability without those assets being treated as "countable" for SSI or Medicaid, as the Special Needs Alliance explains. The person keeps their benefits. The trust supplements what benefits do not cover. That architecture is what makes the grandmother's $75,000 a gift instead of a disaster.
What a special needs trust is (and isn't)
A special needs trust is a legal arrangement in which a trustee — a person or institution — holds and manages assets for the benefit of a person with a disability. The person with the disability is the beneficiary. They do not own the assets and do not receive cash directly; the trustee spends trust money on approved goods and services that improve the beneficiary's quality of life beyond what public benefits already cover.
Because the beneficiary does not own or control the assets, and because the trust language restricts distributions to supplemental purposes, the assets are excluded from resource counts under SSI and Medicaid rules. Federal law authorizes two of the three main types under 42 U.S.C. § 1396p(d)(4), hosted by Cornell's Legal Information Institute.
What a special needs trust is not:
- Not a way to hide assets or evade Medicaid rules. It operates within a strict legal framework; improper drafting or administration can cause the whole thing to be counted as an available resource.
- Not a substitute for benefits. It supplements SSI, Medicaid, and housing assistance — it does not replace them.
- Not a document a family should draft alone from an online form. The rules live in federal statute, state Medicaid manuals, and the SSA's Program Operations Manual System (POMS), and small drafting errors can be very expensive.
The three main types of special needs trust
Almost every SNT falls into one of three buckets, depending on whose money is funding the trust and how much of it there is.
First-party (self-settled, or d(4)(A)) SNT
A first-party SNT is funded with the beneficiary's own assets — typically a personal injury or medical malpractice settlement, an inheritance received outright, or a large SSA back-benefit award. These trusts are authorized under 42 U.S.C. § 1396p(d)(4)(A). Federal law imposes several strict requirements, as summarized by the Special Needs Alliance:
- The beneficiary must be under age 65 when the trust is established and funded.
- The beneficiary must be disabled under the SSA's definition.
- The trust must be established by the beneficiary, a parent, grandparent, legal guardian, or a court. Since the 21st Century Cures Act of 2016, mentally competent beneficiaries can establish their own d(4)(A) trusts.
- On the beneficiary's death, remaining assets must first reimburse every state Medicaid program that paid benefits during the beneficiary's lifetime, up to the total amount paid. Only after this "Medicaid payback" can remaining funds pass to other beneficiaries.
The Medicaid payback is the defining feature of a first-party SNT — and the reason families avoid a first-party trust when a third-party trust is possible.
Third-party SNT
A third-party SNT is funded with someone else's assets — typically a parent, grandparent, sibling, or family friend. Because the funds never belonged to the beneficiary, they are never subject to Medicaid recovery. On the beneficiary's death, whatever remains passes to remainder beneficiaries named by the funder — often surviving siblings, other family members, or a charity.
Third-party trusts can be structured two ways: inter vivos (established during the funder's lifetime, ready today to receive gifts and life insurance proceeds), or testamentary (created through the funder's will and funded only at death). Most special-needs-planning attorneys recommend a standalone inter vivos third-party trust — often called a "stand-alone" or "master" SNT — because it exists during the parents' lifetime as an obvious destination for grandparents and other relatives, so no one accidentally leaves money to the beneficiary directly.
Pooled SNT (d(4)(C))
Pooled trusts, authorized under 42 U.S.C. § 1396p(d)(4)(C), are administered by a nonprofit. Each beneficiary has an individual sub-account, but the nonprofit pools the assets for investment and management.
Pooled trusts can hold first-party or third-party funds. They are often the right fit when trust assets are modest, no family member is willing or able to serve as trustee, the beneficiary is over 65 and needs a first-party option in a state that permits pooled trusts for that age group, or the family values the nonprofit's mission and social-service expertise.
Pooled trusts vary in quality and cost. Ask about setup fees, ongoing management fees, minimum funding levels, distribution policies, and what happens on the beneficiary's death — some retain a portion for the nonprofit's mission, and remaining first-party amounts are subject to Medicaid payback.
The sole-benefit rule
Every special needs trust must be administered for the sole benefit of the disabled beneficiary. This is a rule enforced through SSA's POMS and state Medicaid manuals, and violations can cause the whole trust to be counted as an available resource. In practice: distributions must primarily benefit the beneficiary, not siblings or parents; incidental benefit to others (a wheelchair-accessible van a parent also drives) is allowed only when the primary purpose is the beneficiary's; and trustees should document the purpose of each distribution and keep receipts. This is one of the most common places trusts get into trouble — a special-needs-planning attorney trains trustees on the line before it becomes a problem.
What SNT funds can (and cannot) pay for
The point of an SNT is to pay for things that improve the beneficiary's life beyond bare public benefits. Common allowable distributions:
- Therapies not covered by Medicaid — sensory integration, aquatic therapy, hippotherapy, music and art therapy
- Education and vocational training
- Adaptive equipment, augmentative communication devices, and specialized computers
- Home modifications — ramps, grab bars, accessible bathrooms
- Transportation, including a vehicle titled to the trust or the beneficiary
- Personal care attendants beyond what Medicaid provides
- Recreation, hobbies, and travel — including a companion's travel when needed
- Cell phone, internet, streaming subscriptions, and other quality-of-life technology
- Pets and veterinary care
- Clothing, personal care items, and haircuts
- Funeral and burial expenses, within limits set by SSA
The In-Kind Support and Maintenance (ISM) problem
One category deserves its own paragraph: food and shelter. When a trust pays directly for the beneficiary's food or shelter, SSA treats it as "In-Kind Support and Maintenance" (ISM), which reduces the SSI benefit — sometimes by up to one-third of the Federal Benefit Rate — depending on SSA's evolving ISM rules and the beneficiary's living situation. Shelter includes rent, mortgage, property taxes, homeowner's insurance, utilities, and heating fuel; food is anything eaten. Directly paying rent from the trust does not usually make the person ineligible — it just reduces the SSI check. Sometimes the reduction is worth it (the beneficiary lives in a safer place and loses a modest amount of SSI); other times it is not. This is a judgment call a trustee makes with a special-needs-planning attorney, not alone.
What a trust generally cannot do
- Give cash directly to the beneficiary. Cash is income to SSA in the month received and a resource the following month.
- Pay for things Medicaid already covers.
- Be used to benefit anyone other than the beneficiary as its primary purpose.
- Be treated as available to the beneficiary — meaning the trustee, not the beneficiary, must control every distribution decision.
Choosing a trustee
The trustee is the single most consequential decision a family makes after deciding to create the trust at all. A brilliant trust document with a poor trustee is worse than no trust at all. The trustee will be making SSI/Medicaid-compliant decisions, quarter after quarter, for decades — potentially for the beneficiary's entire adult life.
Families generally consider four options:
- A family member (parent, sibling, aunt or uncle). Family trustees know the beneficiary as a person, often love them, and may serve without a fee. They also may not understand SSI/Medicaid rules, may burn out, may predecease the beneficiary, and may struggle to say "no" to family members who want distributions.
- A professional trustee. Bank trust departments, licensed private fiduciaries, and specialized trust companies bring expertise, longevity, and compliance systems. They charge fees — typically an annual percentage of assets under management (often 1% to 1.5%), sometimes with minimum-fee floors that make small trusts uneconomical.
- A pooled trust nonprofit serving as trustee for the sub-account — often the best option for smaller trusts.
- Co-trustees. A common structure pairs a family member (for personal knowledge) with a professional co-trustee (for compliance, investment management, and continuity).
Whatever the structure, families should name successor trustees several deep. A beneficiary may outlive multiple trustees, and a plan with no living trustee is a plan headed to court.
The Letter of Intent
A Letter of Intent is a non-binding document written by the parents or primary caregivers that describes the beneficiary as a person: routines, preferences, sensory triggers, favorite foods, communication style, medical history, medications, allergies, therapists and doctors, day programs, faith community, closest friends, favorite music — what soothes them, what scares them, what makes them laugh.
It is not part of the trust and does not bind the trustee legally. But when a future trustee — perhaps a professional trustee who never met the beneficiary — is deciding whether to approve a $4,000 request for a specialized summer camp, the Letter of Intent is what tells them, "Yes, camp is one of the four things that has brought this person joy since he was seven." Most attorneys provide a template. Families update it every year or two. It is one of the most loving documents in an estate plan and one of the most underused.
SNTs and ABLE accounts
ABLE accounts — named for the Achieving a Better Life Experience Act of 2014 — are tax-advantaged savings accounts for individuals whose qualifying disability began before a certain age. Historically that age was 26, but under the ABLE Age Adjustment Act it rises to 46 for accounts opened on or after January 1, 2026, per the Social Security Administration's SSI Spotlight on ABLE Accounts.
The key numbers for 2026:
- Annual contribution limit is tied to the federal gift tax exclusion — $19,000 for 2026 — with additional working beneficiary contributions permitted under ABLE to Work.
- Balances up to $100,000 are excluded from the SSI resource limit, per the SSA. Above $100,000, SSI is suspended (not terminated) until the balance drops back below the threshold. Medicaid is not affected by the ABLE balance in most states.
- The ABLE National Resource Center maintains a state-by-state directory of programs.
How the two work together: an ABLE account is often better for smaller, day-to-day expenses — the beneficiary can hold a debit card, exercise more independence, and pay for their own food and shelter without triggering ISM (ABLE payments for "qualified disability expenses," including housing, generally do not reduce SSI). An SNT is better for larger assets, complex investments, life insurance proceeds, settlements, and long-term planning where a trustee's judgment matters. Many families use both: a third-party SNT holds the bulk of assets, and the trustee distributes to an ABLE account periodically for the beneficiary's independent use.
How to fund a special needs trust
An unfunded SNT is a document; a funded SNT is a plan. Sources include:
- Life insurance. Often the single most efficient way to fund a third-party SNT. Parents purchase a permanent (whole or universal) policy and name the SNT — not the child — as the beneficiary. On the second parent's death, the death benefit funds the trust. A second-to-die (survivorship) policy is often more affordable than two individual policies.
- Retirement account beneficiary designations. A parent may name the SNT as beneficiary of an IRA or 401(k). Under the SECURE Act and SECURE 2.0, an "applicable multi-beneficiary trust" for a disabled or chronically ill beneficiary may still stretch distributions over the beneficiary's lifetime, but drafting must be precise. Attorney review is essential.
- Testamentary vs. inter vivos structure. A testamentary SNT is created inside a will and funded at death. An inter vivos SNT exists now, can receive gifts today, and gives grandparents a place to name in their own wills. Most planners recommend an inter vivos structure so extended family has an obvious target.
- Cash gifts and bequests from grandparents, aunts, and uncles via their wills or beneficiary designations.
- Personal injury settlements. Structured settlement payments can be directed into a first-party SNT with careful coordination between settlement counsel and the special-needs attorney.
- Real estate — rarely, and with careful drafting.
- Ongoing family gifts for birthdays, holidays, and graduations.
Trust and estate coordination matters here. A perfectly drafted SNT does nothing if a well-meaning grandfather names the beneficiary directly on his life insurance policy. Every beneficiary designation, every will, and every account title must point to (or through) the SNT.
For the broader picture of what belongs in a trust and how to move assets into one, our guide to living trusts versus wills is a useful companion read.
Coordinating with other benefits
SSI and Medicaid are the two most common concerns, but a full plan considers:
- SSDI — Social Security Disability Insurance is not means-tested. Many people receive both SSI and SSDI; the SNT protects SSI eligibility and, indirectly, Medicaid where Medicaid rides on SSI.
- Disabled Adult Child (DAC) benefits — a person disabled before age 22 may receive Social Security on a parent's work record when the parent retires, becomes disabled, or dies. This affects benefit calculations and sometimes Medicaid eligibility.
- Medicaid waiver programs (HCBS) — state-administered, with their own resource rules and waiting lists.
- Section 8 / HUD housing — subsidized housing has its own income and asset rules; SNT distributions can affect rent calculations.
- SNAP — often follows SSI eligibility.
- Veterans benefits (VA Aid and Attendance, disability compensation) — VA sometimes counts trust assets that SSI does not. Coordination requires an attorney experienced with both systems.
Typical setup costs
Attorney fees vary by state, complexity, and experience. As a general range, expect $2,500 to $7,500 for a well-drafted third-party SNT, often including a coordinated estate plan (wills, powers of attorney, healthcare directives, Letter of Intent template) and a family meeting. Simple SNTs at the lower end are common when a family already has an estate plan and just needs the SNT layered in. Complex situations — a first-party trust funded by a personal injury settlement with structured payments, or intricate retirement-account coordination — run higher. Pooled trusts typically have lower up-front costs (a few hundred to a couple thousand dollars in enrollment fees) but ongoing administration fees over the trust's life.
Compare these numbers to the cost of getting it wrong: a year of lost SSI is roughly $12,000, lost Medicaid coverage can be tens of thousands per year, and untangling an improperly drafted trust often costs more than doing it right the first time.
Common mistakes families make
- Leaving assets outright to a person on SSI/Medicaid in a will. This is by far the most common — and most preventable — mistake.
- Naming the person on benefits as a life insurance or retirement account beneficiary, even after the SNT exists.
- Distributing cash directly from the trust to the beneficiary.
- Paying rent, groceries, or utilities directly from the trust without understanding ISM implications.
- Choosing a trustee who does not understand SSA POMS or Medicaid resource rules.
- Never writing (or updating) a Letter of Intent.
- Failing to tell extended family. Grandparents and aunts must know: never leave money directly to the beneficiary.
- Failing to update the plan after major life events — a move to a new state, a new diagnosis, a change in the trustee's health, the beneficiary approaching age 65 with a first-party trust in play.
How to set up a special needs trust
Start with a family conversation
Before drafting anything, spend time on the vision: What does a good life look like for the beneficiary at 30? At 50? At 70? Where will they live? Who will visit? Who are the trustees-in-waiting, and do they know they are on that list? Some of the most important decisions in special needs planning are not legal at all — they are about who is going to show up, and for how long. If adult guardianship or supported decision-making is also part of the picture, that decision is usually made in coordination with, but separately from, the SNT.
Work with a special-needs-planning attorney
This is not a document to draft yourself from an online template. Attorneys who focus in this area — many of them members of the Special Needs Alliance or comparable specialty groups — understand the interaction between the trust document, SSA POMS, state Medicaid manuals, tax law, and the family's real life. An attorney who drafts one SNT a year is not the same as one who drafts dozens. Ask about experience, ongoing trustee training, and what happens when a rule changes — because the rules do change.
Coordinate the whole estate plan
The SNT is the centerpiece, but wills, revocable trusts, beneficiary designations on life insurance and retirement accounts, 529 plans, and any existing ABLE accounts all have to be aligned. Our overview of how to write a will and our guide to naming a guardian in a will both interact with special needs planning.
Draft a Letter of Intent
Write it. Update it. Store it with the trust document and give copies to successor trustees.
Educate extended family
Every grandparent, aunt, uncle, sibling, and family friend who might one day leave money to the beneficiary needs the same one-sentence instruction: Never leave anything directly to [name]. Always leave it to the trust, followed by the trust's exact legal name. Some families put this on a small printed card that goes with holiday letters.
When to seek professional help
Bring in a special-needs-planning attorney:
- After a diagnosis, even if the child is very young
- Before a personal injury or medical malpractice settlement is finalized
- Before writing or updating a will that includes a person with a disability
- Before an inheritance is paid out — the window to redirect it into a first-party SNT is short
- Before the beneficiary approaches age 65 with a first-party trust in play
- On any major life event: marriage, divorce, birth of a sibling, death of a caregiver, moving to another state
If a person you love has died without an estate plan and a family member with a disability is a legal heir, act immediately. Our guides to dying without a will and the probate process timeline explain what happens by default — which is often catastrophic for a person on means-tested benefits. A special-needs attorney can sometimes redirect an outright inheritance into a first-party SNT or a pooled trust sub-account before it triggers loss of benefits, but only with quick action.
A note on legacy beyond the legal documents
A trust preserves money. It does not preserve the person you are, the values you hold, and the story of why you built any of this. Some families pair their special needs planning with an ethical will — a letter of values and hopes — so the beneficiary, and the trustees who will love them across decades, know not only what to spend but why it was set aside in the first place.
A closing word
A special needs trust is one of the greatest acts of love a family can undertake. It says: your safety, your dignity, and your future will be cared for — even when I am not here. It is not a magic document. It is a promise, structured in law and administered by real people making judgment calls for the rest of the beneficiary's life. Take it seriously, take the planning slowly enough to do it right, and bring in the specialists.
