How to Set Up a Special Needs Trust in the United States (2026): First-Party vs Third-Party and Medicaid Safe Harbor

A special needs trust (SNT) lets a person with a disability hold assets without losing eligibility for Supplemental Security Income (SSI) or Medicaid. The trust owns the assets; the beneficiary does not — so the resources do not count toward the program's asset limits. Two main types exist, each governed by a different section of federal law and carrying different payback obligations.

What a special needs trust actually does

SSI cuts off at $2,000 in countable resources for a single individual (as of 2026 federal rules). Medicaid uses similar or tighter limits depending on the state. Receiving an inheritance or personal injury settlement directly would disqualify a beneficiary immediately.

An SNT solves this by owning the assets in a separate legal entity. The trustee — not the beneficiary — controls distributions, and those distributions pay for goods and services that SSI and Medicaid do not cover: specialized equipment, transportation, recreation, education, and dental work above Medicaid's covered threshold. Cash distributions or anything that substitutes for shelter counts as income and can reduce SSI payments, so the trust document and the trustee's practice must avoid those categories. (Note: as of September 30, 2024, SSA no longer counts food provided by the trust as in-kind support and maintenance; shelter payments remain the primary ISM concern.)

First-party vs third-party: the key split

The type of trust you need depends on whose money is going into it.

First-party (self-settled) SNTs hold assets that originally belonged to the beneficiary — money from a personal injury settlement, an inheritance the person already received, or saved wages. Federal authorization comes from 42 USC § 1396p(d)(4)(A), which is why practitioners call these "(d)(4)(A) trusts" or "payback trusts." Three requirements must be met: the beneficiary must be under age 65 at the time of creation; the trust must be established by a parent, grandparent, legal guardian, or a court (not the beneficiary personally under the original statute, though some states have amended this); and the trust must contain a Medicaid payback provision requiring the state to be reimbursed from remaining assets after the beneficiary's death, up to the amount Medicaid paid on their behalf.

Third-party SNTs hold assets contributed by someone other than the beneficiary — typically a parent setting aside an inheritance, a grandparent naming the trust as a life insurance beneficiary, or siblings pooling funds. No Medicaid payback clause is required because the money never belonged to the beneficiary. Whatever remains in the trust at death can pass to other family members or charities. This flexibility makes third-party trusts the preferred planning tool when families start early.

Pooled trusts are a third category authorized under 42 USC § 1396p(d)(4)(C). A nonprofit manages the trust as part of a larger fund, investing pooled assets together while maintaining a separate sub-account for each beneficiary. Pooled trusts accept beneficiaries of any age and are often the only workable option for adults over 65 who need a first-party solution, since a standalone (d)(4)(A) trust cannot be created after the beneficiary turns 65.

Step 1: choose the right trustee

An SNT trustee carries more responsibility than a standard estate trustee. The trustee must understand Medicaid and SSI rules well enough to make distributions that supplement — rather than replace — public benefits. Paying rent directly to a landlord, for instance, counts as in-kind support and reduces SSI by up to one-third of the federal benefit rate. Paying a telephone bill or internet service does not.

Family members frequently serve as trustees, especially for third-party trusts. A co-trustee arrangement — one family member plus a professional trustee or trust company — gives the beneficiary a personal advocate alongside someone with the technical knowledge to avoid benefit disruptions. A successor trustee must also be named; SNTs often last decades.

The trust document should explicitly authorize the trustee to hire a benefits counselor, a Social Security Administration work incentives coordinator, or an elder law attorney when distribution questions arise. Building this authority into the instrument is cheaper than drafting an amendment later.

Step 2: draft the trust document

The trust must be in writing and must meet the drafting requirements for trusts in the state where it is created. Beyond state formalities, an SNT needs several federal-law provisions to function correctly.

For a first-party (d)(4)(A) trust, the document must:

• Name the beneficiary as the sole lifetime beneficiary
• Include the Medicaid payback clause with accurate state agency identification
• Prohibit distributions that substitute for food, shelter, or cash
• Specify what happens if the trust corpus falls to zero during the beneficiary's lifetime

For a third-party trust, the payback clause is absent, but the document should address:

• A detailed statement of purpose explaining the intent to supplement public benefits
• Discretionary (not mandatory) distribution language — mandatory distributions can be counted as available resources
• Spendthrift provisions preventing the beneficiary from assigning the interest to creditors
• Remainder beneficiaries and what triggers final distribution

State laws layer on top of federal requirements. California's Special Needs Trust Act under Probate Code §§ 3600–3613 adds court approval requirements for certain trusts funded with litigation proceeds. New York's EPTL § 7-1.12 governs supplemental needs trusts, a closely related structure under state law. Texas Trust Code Chapter 112 controls formation and modification.

You can use a free special needs trust template from forms-legal.com as a starting point — every SNT should be reviewed by an attorney who handles public benefits law before funding, but a well-drafted template reduces the attorney's time and your cost.

Step 3: fund the trust correctly

Funding an SNT means transferring ownership of assets into the trust's name. The mechanics vary by asset type.

Cash and investment accounts require a new account in the trust's name (e.g., "John Smith, Trustee of the Jane Smith Special Needs Trust dated [date]"). The bank or brokerage needs a copy of the trust document or a Certificate of Trust — not the full instrument — before opening the account.

Real property transfers require a deed from the current owner to the trustee. Recording fees and state transfer taxes may apply, though many states exempt transfers to SNTs from real estate transfer tax.

For first-party trusts funded with litigation proceeds, the settlement agreement should direct payment to the trustee rather than to the beneficiary. Once money lands in the beneficiary's hands and is then transferred to the trust, Medicaid may treat the transfer as a disqualifying transfer subject to a penalty period under 42 USC § 1396p(c).

Life insurance and retirement accounts name the trust as beneficiary through the insurer or plan administrator's beneficiary designation form — not through the trust document itself. Naming the trust as a direct beneficiary of a 401(k) or IRA has income tax consequences under the SECURE Act 2.0 (Pub. L. 117-328). A properly structured SNT for a disabled or chronically ill beneficiary can qualify as a see-through trust and allow stretch distributions over the beneficiary's life expectancy — but only if the trust meets specific IRS requirements, including the sole-benefit rule. An attorney or CPA should review retirement account designations before finalizing them.

Step 4: notify SSA and the state Medicaid agency

After funding a first-party SNT, the beneficiary (or their representative) must report the trust's existence to the Social Security Administration. SSA evaluates whether the trust qualifies under the (d)(4)(A) safe harbor. If it does not — because of a drafting error, an improper payback clause, or because assets subject to the trust were not properly categorized — SSA can count the trust as an available resource.

The Program Operations Manual System (POMS) section SI 01120.200 through SI 01120.225 contains SSA's internal instructions for evaluating SNTs. These sections are publicly available and provide detailed guidance on what SSA scrutinizes.

State Medicaid agencies have their own notification rules. Some states require advance approval before an SNT is funded; others review the trust at the time of a Medicaid application or redetermination. Failing to notify the state risks a Medicaid penalty period or disqualification.

The over-65 problem

Federal law under 42 USC § 1396p(d)(4)(A) prohibits creating a first-party SNT for a beneficiary who is 65 or older. The prohibition applies to the date of trust creation, not the date of funding. Someone who turns 65 between signing the trust and depositing money into it faces a disqualification problem.

Pooled trusts under (d)(4)(C) have no age cap and are the standard workaround for older beneficiaries. However, some states impose their own transfer penalty for assets contributed to a pooled trust by a person over 65, treating the contribution like a disqualifying gift. New York does not impose this penalty; California and Florida have taken different positions depending on the circumstances. State-specific advice is mandatory for this scenario.

What the trustee cannot pay for

The trustee controls distributions, but the wrong distribution can reduce or terminate SSI benefits. SSI defines "in-kind support and maintenance" (ISM) as shelter paid to or for the beneficiary. Following an SSA regulatory change effective September 30, 2024, food is no longer counted as ISM, so the trust may now pay for food without reducing SSI benefits. Shelter items that still qualify as ISM under 20 CFR § 416.1130 include rent, mortgage payments, real property taxes, heating fuel, gas, electricity, water, and sewerage.

When the trust pays ISM directly, SSI reduces the monthly payment by one-third of the federal benefit rate plus $20 — a formula called the Presumed Maximum Value (PMV) rule. In 2026, the federal benefit rate is $994 per month for an individual, making the PMV $351.33 (one-third of $994, plus $20). One month of ISM can cost the beneficiary up to $351.33 in SSI income. Over a year, the maximum reduction approaches $4,200.

Trustees should direct distributions toward non-ISM items: medical equipment not covered by Medicaid, personal care attendants beyond Medicaid hours, computers and assistive technology, education, transportation, vacations, entertainment, clothing, and household items that are not food. Some trustees use a pre-approved "wish list" process, where the beneficiary or family proposes distributions and the trustee confirms they fall outside ISM before writing the check.

Common drafting errors to avoid

A missing or defective Medicaid payback clause in a first-party trust is the most consequential error. SSA will not recognize the trust as a (d)(4)(A) trust, and the entire corpus becomes a countable resource. Medicaid may also impose a transfer penalty on the trust funding as a disqualifying transfer.

Using mandatory distribution language instead of discretionary language is a second frequent mistake. If the trust says the trustee "shall distribute" a set amount monthly, SSA treats that amount as income. If the trustee "may distribute," the trust retains the flexibility that makes it work.

Naming the beneficiary as the trustee of a self-settled first-party trust used to be prohibited under the original (d)(4)(A) statutory text; the Special Needs Trust Fairness Act of 2016 (Pub. L. 114-255, § 5007) amended 42 USC § 1396p to allow the beneficiary to establish the trust themselves, but only where the beneficiary has legal capacity to do so. Guardianship situations require the guardian or a court to establish the trust.

A practical setup checklist

Before finalizing an SNT, confirm the following:

1. The beneficiary qualifies for SSI or Medicaid based on disability — SNTs serve no purpose without a public benefit to protect.
2. The source of funds determines first-party vs third-party structure.
3. For first-party trusts, the beneficiary is under 65 at trust creation.
4. The trust document contains the correct Medicaid payback language for the state.
5. A trustee with knowledge of public benefits rules has agreed to serve.
6. The trust was reviewed by a licensed attorney — ideally one who holds the NAELA (National Academy of Elder Law Attorneys) designation.
7. SSA and the state Medicaid agency have been notified after funding.

A well-structured special needs trust can hold assets for decades without ever triggering a benefit reduction. Getting the initial document right matters far more than the funding amount.
