First-Party vs. Third-Party Special Needs Trust

A special needs trust is not a single legal instrument — it is a category that encompasses two structurally different trust types whose mechanics, tax treatment, and long-term consequences diverge significantly based on one question: whose money funded the trust? If the money comes from someone other than the person with a disability — a parent, grandparent, or other family member — the trust is a third-party SNT. If the money originated with the person with a disability themselves — a personal injury settlement, an inheritance received directly, earnings accumulated before the trust was established — the trust is a first-party SNT. That single distinction determines whether Medicaid can claim the remaining assets at the beneficiary's death, who can create the trust, and how it interacts with federal benefit programs.

For tech workers building an estate plan around a child with a disability, the practical answer is almost always the same: establish a third-party SNT funded by the parent's assets. But understanding why — and understanding when a first-party SNT becomes necessary — matters for parents who are navigating an inheritance, a legal settlement, or assets already held in the child's name.

Third-Party Special Needs Trusts: The Estate Planning Tool

A third-party SNT is funded entirely with assets belonging to someone other than the beneficiary. The parent who creates the trust contributes their own IRA proceeds, brokerage assets, life insurance death benefit, or real estate. A grandparent who wants to leave assets to a grandchild with a disability funds the trust from their own estate. The defining characteristic: not one dollar of the beneficiary's own assets has ever been in the trust.

Who can create it: Any person — a parent, grandparent, sibling, aunt, uncle, family friend — can create and fund a third-party SNT. There is no requirement that the grantor be related to the beneficiary, though in practice the trust is almost always created by parents as part of their estate plan.

No Medicaid payback requirement: When the beneficiary dies, whatever remains in a third-party SNT passes to whoever the trust document designates as remainder beneficiaries — other children, grandchildren, a charity, or any other named party. The state has no claim on those assets. Medicaid receives nothing from a third-party trust at the beneficiary's death, regardless of how much Medicaid spent on the beneficiary's care over their lifetime.

Asset limits and government benefits: Assets held in a properly drafted third-party SNT are not counted as the beneficiary's resources for SSI or Medicaid purposes. The trust must be structured as a discretionary supplemental needs trust — the trustee has discretion over whether to distribute, and distributions are limited to supplemental expenses beyond what government programs provide. A trust that requires the trustee to make distributions or that allows the beneficiary to demand distributions on their own authority may not qualify for the SSI resource exclusion.

Timing: A third-party SNT is most powerful when established before any assets are transferred to or for the benefit of the beneficiary. The trust should be named as the beneficiary on the parent's IRA, 401(k), life insurance policy, and any other asset that would otherwise pass directly to the child. Assets that reach the child directly — before being redirected to the trust — may trigger SSI disqualification or require a first-party trust to preserve benefits.

Tax treatment: A third-party SNT created and funded by a living parent is typically structured as a grantor trust during the parent's lifetime, meaning all income is taxed on the parent's individual return at their rates. After the parent's death, the trust becomes a non-grantor trust and files its own Form 1041 at compressed trust tax rates — reaching the 37% federal bracket at just $16,000 of undistributed income in 2026. This makes it important for the trustee to distribute trust income to the beneficiary where possible, allowing it to be taxed at the beneficiary's typically much lower individual rate.

First-Party Special Needs Trusts: When the Money Is Already the Beneficiary's

A first-party SNT — also called a self-settled trust or a payback trust — is funded with assets that legally belong to the person with a disability. The most common scenarios where a first-party SNT becomes necessary:

Personal injury settlement. A person with a disability receives a large legal settlement for medical malpractice, an accident, or another claim. The settlement proceeds belong to them. If they receive those funds directly and hold more than $2,000 in countable assets, they lose SSI and Medicaid immediately. A first-party SNT allows the settlement to be placed in trust, preserving benefit eligibility while the funds remain available for supplemental needs.

Direct inheritance. A well-intentioned relative leaves money directly to the person with a disability — in a will, as a named beneficiary on a retirement account, or outright. If the inheritance arrives in the beneficiary's hands before being redirected to a trust, a first-party SNT may be the only option to preserve benefits. This is one of the primary reasons estate plans for families with a child with a disability must proactively name the third-party SNT as the beneficiary on every relevant account — to prevent assets from ever reaching the child directly.

Accumulated assets. A person who developed a disability later in life — after accumulating savings, owning a home, or building an investment portfolio — may need to restructure their own assets into a first-party SNT to qualify for Medicaid coverage for long-term care.

Who can create it: Federal law (42 U.S.C. § 1396p(d)(4)(A)) requires that a first-party SNT be established by the individual with a disability, a parent, grandparent, legal guardian, or a court. The beneficiary must be under age 65 when the trust is established and funded. Assets added to the trust after the beneficiary turns 65 do not qualify for the resource exclusion.

The Medicaid payback requirement: This is the defining limitation of a first-party SNT. At the beneficiary's death, any assets remaining in the trust must first be used to reimburse the state (or states) for all Medicaid benefits paid on the beneficiary's behalf during their lifetime. Only after the state's claim is fully satisfied can any remainder pass to other heirs. If Medicaid has paid $800,000 in care over 30 years and the trust has $400,000 remaining, the entire $400,000 goes to the state. If the trust has $1,200,000 remaining, $800,000 goes to the state and $400,000 passes to designated remainder beneficiaries. For families hoping to preserve assets across generations, this payback requirement fundamentally limits the first-party SNT as an inheritance vehicle.

Pooled trust as alternative: For individuals with smaller assets or those over 65 who cannot use a (d)(4)(A) first-party trust, a pooled special needs trust managed by a nonprofit organization — established under 42 U.S.C. § 1396p(d)(4)(C) — provides similar benefit protection with the same Medicaid payback requirement at death.

Side-by-Side Comparison

The SECURE Act and Inherited IRAs: How SNT Type Changes the Analysis

The SECURE Act of 2019 eliminated the stretch IRA for most non-spouse beneficiaries, requiring inherited IRA distributions within 10 years. The law created a narrow exception for "eligible designated beneficiaries" — a category that includes individuals with disabilities. If a person with a disability qualifies as an eligible designated beneficiary, they can still stretch inherited IRA distributions over their own life expectancy, rather than being forced into the 10-year window.

The complication: when the IRA is left to a trust rather than directly to the person, the trust must meet specific requirements to qualify for the eligible designated beneficiary exception. The IRS requires what is called a "qualified disability trust" under IRC Section 642(b)(2)(C) — a trust that meets strict conditions including that all present beneficiaries are disabled under Social Security's definition.

For a third-party SNT: The trust can potentially qualify as a qualified disability trust and allow the inherited IRA to be stretched over the beneficiary's life expectancy — but only if the trust document meets the specific IRS requirements. A generic SNT drafted without attention to the SECURE Act's trust rules may not qualify. This is one of the most technically demanding intersections in estate planning today, and the trust must be specifically drafted to address it. See Special Needs Trust as IRA Beneficiary for a complete treatment of the accumulation trust rules, the eligible designated beneficiary exception, and the Roth IRA considerations.

For a first-party SNT: The Medicaid payback requirement interacts in an especially problematic way with inherited IRA proceeds. When an IRA distribution flows into a first-party SNT, those distributions are income to the trust and taxable at trust rates. Because the state's Medicaid payback claim reaches all remaining assets at death — including any accumulated IRA proceeds sitting in the trust — the combination of trust-level income tax and eventual Medicaid clawback can make a first-party SNT a poor vehicle for large inherited IRA assets. In most cases, a Roth conversion strategy — converting traditional IRA assets to Roth before the parent's death — is a more effective approach when the intended beneficiary is a person with a disability who receives Medicaid. Tax-free Roth distributions reduce the income tax cost inside the trust, and the lower ongoing income improves the trust's efficiency during the beneficiary's lifetime.

Common Mistakes That Force a First-Party Trust When a Third-Party Trust Was Intended

The most preventable estate planning error in this area is allowing assets to pass directly to a beneficiary with a disability before being redirected to a third-party SNT. Several common triggers:

Outdated beneficiary designations. A parent names their child directly as a beneficiary on a 401(k) or life insurance policy before the child is diagnosed with a disability, or before the parent creates a third-party SNT. The parent dies without updating the designation. The IRA or insurance proceeds go directly to the child, immediately disqualifying them from SSI and Medicaid. A first-party SNT may then be used to shelter the proceeds — but the Medicaid payback requirement now applies to assets the family intended to pass freely to heirs.

Intestate succession. A parent dies without a will, and state intestacy laws direct a share of the estate to the child with a disability. If there is no trust already in place, the assets pass outright to the child.

Direct bequest in a will. A will that leaves assets directly to the child rather than to the SNT — either because the SNT didn't exist at the time the will was drafted or because it was not updated after the SNT was created.

Gifts from well-meaning relatives. A grandparent or aunt leaves money directly to the grandchild or niece/nephew with a disability, not knowing that the third-party SNT exists and should be the recipient.

Each of these situations can potentially be remedied after the fact — a first-party SNT can be established to receive the assets and restore benefit eligibility — but the Medicaid payback requirement applies from that point forward to whatever entered the first-party trust. The remedy is more expensive and less efficient than simply having named the third-party SNT correctly from the beginning.
