Special Needs Trust Massachusetts: How to Protect Benefits Without Losing Eligibility

Your adult child qualifies for SSI and MassHealth. A relative wants to leave them an inheritance. Without a plan, that inheritance hits their bank account, pushes countable assets past the $2,000 SSI resource limit, and can put their SSI eligibility at risk.

This is the exact scenario a special needs trust is designed to prevent — and in Massachusetts, the rules around how these trusts are structured, taxed, and funded have specific state-level wrinkles that matter.

What a Special Needs Trust Actually Does

A special needs trust (also called a supplemental needs trust, or SNT) holds assets for a person with a disability without those assets counting toward the $2,000 SSI resource limit or MassHealth eligibility thresholds. The trust pays for supplemental needs — things SSI and MassHealth do not cover — like specialized therapies, recreation, personal electronics, and transportation.

The trustee (not the beneficiary) controls the funds. Distributions are commonly made directly to vendors or service providers rather than to the beneficiary as cash. This structure keeps the trust assets out of SSA's countable-resource calculation.

Third-Party vs. First-Party: The Split That Determines Everything

Massachusetts recognizes two fundamentally different types of special needs trusts, and the distinction controls whether remaining funds go to your family or to the state when the beneficiary dies.

Third-Party Special Needs Trust

A third-party SNT is funded exclusively with other people's money — parents, grandparents, aunts, uncles, or estate distributions. Because the beneficiary never owned the assets, there is no Medicaid payback requirement. When the beneficiary dies, remaining trust funds pass to whatever heirs you designate in the trust document.

This is the trust most Massachusetts families set up during transition planning. Parents name the trust as a beneficiary of their life insurance, retirement accounts, or estate plan, and the trust captures those assets without disrupting the adult child's benefits.

First-Party Special Needs Trust

A first-party SNT is funded with the beneficiary's own assets — direct inheritances received outside a trust, litigation settlements, retroactive SSA lump-sum payments, or accumulated earnings. Federal law requires that this trust type include a mandatory Medicaid payback provision: when the beneficiary dies, MassHealth gets reimbursed for all medical assistance it provided before any remaining balance passes to family heirs.

A first-party trust must also be established before the beneficiary turns 65. For individuals who receive an unexpected inheritance or settlement after age 18, this is often the only tool that can shelter those funds quickly enough to avoid an SSI overpayment finding.

Massachusetts Tax Rules for Trust Income

Under the Massachusetts Fair Share Amendment, trust income is subject to a flat 5% state income tax rate. For tax year 2026, trust income exceeding $1,107,750 triggers an additional 4% surtax, bringing the effective rate to 9% on the excess.

Most disability-related trusts will never approach that surtax threshold. But families with substantial assets — particularly those funding a first-party trust with a large litigation settlement — need to model the tax impact with an accountant before the trust is funded.

How SNTs Work Alongside ABLE Accounts

An ABLE account (marketed in Massachusetts as the Attainable Savings Plan through MEFA and Fidelity) is a lighter-weight complement to a trust, not a replacement. The key differences:

• ABLE annual contribution limit: $20,000 for 2026, with an additional ABLE-to-Work contribution of up to $15,960 for employed beneficiaries who do not participate in a retirement plan
• ABLE SSI disregard: the first $100,000 in an ABLE account is completely excluded from SSI resource calculations
• ABLE eligibility: as of January 1, 2026, disability onset must have occurred before age 46 (expanded from the previous age-26 limit)

Many Massachusetts families use a dual strategy: the SNT holds the bulk of the family's planned assets (life insurance proceeds, estate distributions), while the ABLE account handles smaller, more accessible spending — personal electronics, subscriptions, clothing purchases — without requiring trustee involvement for every transaction.

When You Need an Attorney vs. When You Do Not

Not every family needs a custom-drafted trust. If the only goal is to shelter small amounts (under $100,000) from SSI asset counting, an ABLE account alone may suffice. But you need specialized counsel in Massachusetts if:

• You plan to fund a first-party trust with a settlement or direct inheritance (the Medicaid payback clause must be properly drafted)
• Your family's combined assets exceed the $2 million Massachusetts estate tax threshold
• You need to coordinate the trust with a guardianship or conservatorship decree from Probate and Family Court
• Multiple family members want to contribute to the trust across different estate plans

General practitioners often miss the intersection of federal SSI rules with Massachusetts-specific tax and Medicaid provisions. A special needs planning attorney ensures the trust structure actually preserves the benefits it is meant to protect.

The Connection to Guardianship and Conservatorship

A special needs trust does not require a guardianship or conservatorship to exist. If the adult with a disability has the capacity to understand and sign legal documents, they can be involved in the trust's creation and management without any court proceeding.

But when guardianship or conservatorship is already in place — or when the adult lacks capacity to participate in trust decisions — the guardian or conservator often becomes the person who interacts with the trustee on the beneficiary's behalf. In Massachusetts, a conservator who manages the protected person's assets may need court approval to fund a first-party trust, since it involves transferring the protected person's own property.

If you are navigating both the guardianship decision and financial planning for your adult child, mapping the options side by side — rather than treating them as separate projects — prevents costly mistakes.
