The difference between a first-party and a third-party special needs trust comes down to one fact: whose money funds it. A first-party trust holds assets that already belong to the person with a disability, usually a personal injury settlement or an inheritance. A third-party trust holds assets contributed by someone else, typically a parent or grandparent planning for a disabled loved one. That single distinction controls who can create the trust, whether an age limit applies, what the trustee can spend money on, how the income is taxed, and whether the state gets repaid for Medicaid at the beneficiary’s death. Both types keep assets out of the resource count for means-tested programs like SSI and Medicaid, where a single person generally cannot hold more than $2,000 in countable resources.
Whose Money Funds the Trust
A first-party special needs trust is funded with assets the beneficiary already owns or is legally entitled to receive. A lawsuit settlement, back-pay award, or direct inheritance are the most common sources. Without the trust, that money would push the beneficiary over the resource limit and end their benefits. Federal law carves out an exception at 42 U.S.C. § 1396p(d)(4)(A), which keeps a properly drafted trust from being treated as an available resource for Medicaid purposes.1Office of the Law Revision Counsel. 42 USC 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets
A third-party trust is funded entirely with someone else’s money. Parents and grandparents set up most of them, but anyone can create one with their own assets. Because the beneficiary never owned the funds, no federal exemption is needed to keep them off the resource ledger. The assets simply are not the beneficiary’s.
What a First-Party Trust Requires
First-party trusts carry tighter rules because the government is making an exception by ignoring what is technically the beneficiary’s own money.
The Beneficiary Must Be Under 65
The trust must be funded before the beneficiary turns 65.1Office of the Law Revision Counsel. 42 USC 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets Adding assets after that birthday is treated as a disqualifying transfer, which triggers a Medicaid penalty period. For someone already past 65, a pooled trust may be available, though not in every state.
Every Dollar Must Benefit the Disabled Person
The sole-benefit rule is the one trustees stumble over most often. When the trustee pays a third party for goods or services, those goods or services must be primarily for the beneficiary.2Social Security Administration. SI 01120.201 – Trusts Established with the Assets of an Individual A trust can pay a caregiver’s travel costs when accompanying the beneficiary, or compensate a relative for daily care, but it cannot buy a gift for a sibling or fund a family vacation. Items that get titled, like a vehicle, must be titled to the beneficiary or the trustee. A violation can cause the whole trust to be counted as an available resource, which ends benefits immediately.
Who Can Set It Up
The statute originally restricted creation of a first-party trust to a parent, grandparent, legal guardian, or court. Section 5007 of the 21st Century Cures Act, often called the Special Needs Trust Fairness Act, added the disabled individual to that list in 2016, so a person with a disability who has legal capacity can now create their own.1Office of the Law Revision Counsel. 42 USC 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets Before that, a competent adult who received a settlement still had to go to court to establish the trust.
First-party trusts must be irrevocable.
What a Third-Party Trust Allows
Third-party trusts operate with much more flexibility because no federal exemption is at stake. The government has little reason to restrict what families do with their own money so long as the beneficiary does not control it.
There is no age restriction on the beneficiary, which makes this the right vehicle for an adult child approaching or past 65. Anyone can be the grantor, and the trust can name any person or charity as remainder beneficiary. The grantor can also keep the trust revocable during their lifetime, which usually converts to irrevocable at death. The sole-benefit rule does not apply, so distributions can incidentally benefit other people. A trip the beneficiary attends with family, or a home shared with a caretaker, are both permissible uses that would be problematic in a first-party trust.
Medicaid Payback at the Beneficiary’s Death
This is where the two trusts separate most dramatically in dollar terms. When a first-party trust beneficiary dies, the state Medicaid agency must be repaid for every dollar of medical assistance it provided during the beneficiary’s lifetime. The trust document must contain a provision ensuring the state receives the remaining assets up to the full amount Medicaid spent.1Office of the Law Revision Counsel. 42 USC 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets If a trust holds $100,000 at death and Medicaid spent $150,000, the state takes the full $100,000 and remaining heirs get nothing. The Medicaid claim has priority over nearly all other end-of-life expenses, including funeral costs.
Third-party trusts owe nothing to the state. The remainder passes to whomever the grantor named, whether siblings, children, or a charity. That preservation of family wealth is the main reason estate planners reach for a third-party structure whenever the funding source permits it.
How the Two Trusts Are Taxed
First-party and third-party trusts fall into different federal tax categories, and the gap between them is substantial.
A first-party special needs trust is typically treated as a grantor trust because it holds the beneficiary’s own assets. The income is reported on the beneficiary’s personal return rather than a separate trust return, which is usually favorable because individual brackets are much wider than trust brackets.
A third-party trust is usually a complex (non-grantor) trust that files its own return on IRS Form 1041. Trust brackets are compressed to the point of being punitive. For 2026, the top 37% rate hits at just $16,000 of taxable income.3Internal Revenue Service. Revenue Procedure 2025-32 An individual would not reach the same rate until income passed several hundred thousand dollars. The full 2026 schedule for trusts:
- $0 to $3,300: 10%
- $3,300 to $11,700: 24%
- $11,700 to $16,000: 35%
- Over $16,000: 37%
Qualifying as a qualified disability trust can soften that hit. Federal law allows a qualified disability trust an annual exemption significantly larger than the standard $100 complex-trust exemption.4Office of the Law Revision Counsel. 26 USC 642 – Special Rules for Credits and Deductions Every beneficiary must be disabled as determined by SSA, and the trust must be established under 42 U.S.C. § 1396p(d)(4). Distributing income to the beneficiary during the tax year is another way to shift the liability to the beneficiary’s individual return.
How Trust Spending Affects SSI
Not every trust payment is invisible to Social Security, and the distinction matters for both trust types.
Payments the trust makes for shelter, including rent, mortgage, and utilities, are treated as in-kind support and maintenance. SSI is reduced, but only up to the presumed maximum value, which is one-third of the federal benefit rate plus $20. For 2026, with the individual federal benefit rate at $994, that cap comes to roughly $351.5Social Security Administration. SSI Federal Payment Amounts for 2026 Even a $3,000 monthly rent payment produces no reduction larger than the cap.
As of September 30, 2024, food no longer counts in these calculations.6Social Security Administration. SSI Spotlight on Trusts Trusts can pay for groceries, meal delivery, or restaurants without any SSI reduction. Payments for clothing, medical care, education, personal care, and entertainment have never counted. Cash paid directly to the beneficiary, by contrast, is income and reduces SSI dollar for dollar after a $20 monthly exclusion, which is why trustees almost never distribute cash.
Pooled Trusts When a First-Party Trust Does Not Fit
A third category exists under 42 U.S.C. § 1396p(d)(4)(C). A nonprofit organization establishes and manages a pooled trust, keeping a separate account for each beneficiary while pooling the assets for investment.1Office of the Law Revision Counsel. 42 USC 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets A pooled trust fills two gaps the individual first-party trust leaves open: it provides a trustee when no family member can serve, and it has no age limit on the beneficiary.
The payback rule is slightly different. At the beneficiary’s death, any funds not retained by the nonprofit must be paid to the state for Medicaid reimbursement.1Office of the Law Revision Counsel. 42 USC 1396p – Liens, Adjustments and Recoveries, and Transfers of Assets The nonprofit can keep a share to fund its mission and support other beneficiaries, so less typically ends up with the state than from an individual first-party trust. For someone 65 or older, a pooled trust may be the only shelter available for their own assets, though several state Medicaid agencies treat transfers into a pooled trust by someone over 65 as penalizable, which creates an ineligibility period. The outcome depends on the state.
Quick Comparison
- Funding source: first-party uses the beneficiary’s own assets; third-party uses anyone else’s.
- Age limit: first-party requires the beneficiary to be under 65; third-party has none.
- Medicaid payback: first-party reimburses the state at death; third-party owes nothing.
- Sole-benefit rule: first-party spending must exclusively benefit the disabled person; third-party allows broader distributions.
- Revocability: first-party must be irrevocable; third-party can be revocable while the grantor is living.
- Taxes: first-party income flows to the beneficiary’s personal return; third-party trusts file their own at compressed rates unless they qualify as a qualified disability trust or distribute income out.
- Who can create it: first-party is limited to the individual, a parent, grandparent, guardian, or court; third-party can be created by anyone using their own funds.
When the beneficiary already has money that needs protecting, a first-party trust is usually the only option. When family members are setting aside their own money for a disabled loved one, a third-party trust preserves far more wealth because the Medicaid payback never attaches. Many families end up running both at the same time, each matched to its funding source.
