A Special Needs Trust — often called an SNT — is a legal arrangement that lets a person with a disability hold assets without those assets counting against SSI (Supplemental Security Income) or Medicaid eligibility. Without an SNT, receiving an inheritance, a lawsuit settlement, or a large gift could disqualify someone with a disability from benefits they depend on.
With a properly structured SNT, the same money can be held and used for the person’s benefit — without triggering disqualification.
The core problem an SNT solves
SSI has a strict asset limit: $2,000 for an individual. If your countable assets exceed that amount, you lose SSI — and in most states, Medicaid goes with it.
Medicaid is often more valuable than the SSI cash payment. It covers healthcare, home-based support services, and equipment that private insurance typically won’t. Losing it over an inheritance or lawsuit settlement — and then spending down those assets until you qualify again — is exactly what an SNT is designed to prevent.
The legal logic: assets held in a properly structured SNT are not the beneficiary’s assets. They belong to the trust. The beneficiary benefits from the trust’s resources, but does not own them directly. Social Security and Medicaid look at what you own, not what benefits you — so trust assets typically don’t count against eligibility.
The three main types of Special Needs Trusts
First-party SNTs (also called d(4)(A) trusts or self-settled trusts)
A first-party SNT is funded with the beneficiary’s own assets — money that already belonged to them. Common sources: a personal injury settlement, an inheritance received directly by the person, or other assets they personally owned.
Because the money started as the beneficiary’s own property, the IRS and Social Security impose one major condition: Medicaid payback. When the beneficiary dies, the state must be reimbursed for all Medicaid costs paid on their behalf during their lifetime before any remaining assets can pass to heirs.
First-party SNTs must be established by a parent, grandparent, legal guardian, or court — not by the beneficiary themselves. The beneficiary must be under age 65 when the trust is created.
Third-party SNTs
A third-party SNT is funded with someone else’s assets — typically a parent, grandparent, sibling, or other family member. The beneficiary never owned the money going into the trust.
Because the beneficiary never owned those funds, there is no Medicaid payback requirement. When the beneficiary dies, remaining assets can pass to other heirs — children, siblings, charities — according to the trust document.
Third-party SNTs are the most common tool for family estate planning. Parents who want to leave assets for a disabled child without jeopardizing their benefits almost always use a third-party SNT. They can be established during the grantor’s lifetime or through a will.
Pooled trusts (also called d(4)(C) trusts)
A pooled trust is administered by a nonprofit organization that manages funds for many beneficiaries together — pooling investments for efficiency while maintaining separate accounts for each beneficiary.
Pooled trusts can be first-party or third-party, depending on the source of funds. They are particularly useful for people with smaller amounts to protect, where the cost of setting up a standalone SNT may not be justified. The nonprofit trustee handles all administration.
Who serves as trustee?
The trustee manages the trust — deciding when and how to make distributions on behalf of the beneficiary. This is a significant responsibility. The trustee must:
- Understand the rules governing what trust funds can and cannot pay for without affecting SSI or Medicaid
- Keep detailed records of all transactions
- File annual trust tax returns (trusts have their own tax obligations)
- Act solely in the interest of the beneficiary
A family member can serve as trustee, but it comes with real administrative complexity and legal liability. Professional trustees (banks, trust companies, or nonprofit organizations) handle this expertise routinely. Many families use a combination: a family co-trustee for personal knowledge of the beneficiary’s needs, alongside a professional co-trustee for the administrative work.
What trust funds can — and cannot — pay for
This is where SNTs require careful management. The rules around spending are tied to how SSI counts certain types of support.
Generally fine: Education, recreation, travel, electronics, personal care items, clothing beyond basic needs, therapy, out-of-pocket medical expenses not covered by Medicaid, and other expenses that supplement government benefits without replacing them.
Requires care: Cash given directly to the beneficiary counts as income to them and can reduce SSI. Direct payment of food or housing costs can trigger a reduction in SSI under a rule called in-kind support and maintenance (ISM). Trustees typically pay vendors directly rather than giving cash to the beneficiary.
Note on housing: SNT funds can pay for housing, but doing so may reduce SSI by up to one-third due to ISM rules. This is different from an ABLE account, where paying your own housing costs from the account does not trigger ISM. Many families use an SNT for large assets and an ABLE account for housing and daily expenses — see our comparison of ABLE accounts vs. Special Needs Trusts.
When do you actually need an SNT?
Not everyone with a disability needs an SNT. It depends on your situation:
You likely need an SNT if:
- You or a family member is about to receive a significant inheritance, lawsuit settlement, or life insurance payout
- You are a parent planning your estate and want to leave assets for a disabled child without disqualifying them from benefits
- The amount involved is large — more than ABLE account annual contribution limits could absorb over time
You may not need an SNT if:
- The amount involved is small and can be moved into an ABLE account within annual limits
- You do not receive SSI or Medicaid and have no benefits at risk
- Your disability does not qualify you for any means-tested benefits
If you are unsure, consult a special needs attorney before any funds are transferred. Once money hits your name directly, it may be very difficult to undo.
Cost and setup
A standalone SNT requires a licensed attorney to draft. Setup costs typically range from $2,000 to $5,000 or more, depending on complexity and location. Ongoing trustee fees, accounting, and tax filing add annual costs.
Pooled trusts often have lower setup costs — some nonprofit pooled trust programs charge a few hundred dollars to join.
The cost is real. For small amounts, the cost of establishing an SNT may not be justified. In those cases, an ABLE account is often a better first step.
What this means for you
- If a family member is leaving assets to a disabled person, the assets should go into a third-party SNT — not directly to the person. Receiving assets directly can trigger a loss of SSI and Medicaid. Talk to an estate planning attorney before the will is finalized.
- If you have received a settlement, inheritance, or other windfall that would put you over SSI’s $2,000 limit, talk to a special needs attorney immediately. Do not spend the money until you understand your options.
- Pooled trusts are a good option for smaller amounts where a standalone SNT isn’t cost-effective. Find a nonprofit pooled trust program in your state.
- An ABLE account is a complementary tool — not a replacement for an SNT. The SNT handles large asset protection; the ABLE account handles day-to-day spending flexibility.
- The trustee role matters. If a family member serves as trustee, make sure they understand the rules. Professional trustees are worth the cost for larger trusts.
