How It Works

Funding a Special Needs Trust (SNT) without tripping the eligibility limits on government programs takes careful planning, and this tool puts the fixed 2026 benchmarks for that planning on one screen. The goal is to keep a beneficiary qualified for support such as Supplemental Security Income (SSI), with a maximum federal benefit rate of $994 per month for an individual in 2026, and Medicaid, while avoiding the excess resources that would cut off access. Seeing those interactions clearly is central to building durable, long-term financial security.

The figures are the same whichever disability type you pick: the SSI federal benefit rate of $994 a month ($11,928 a year), the $20,000 that can be deposited into an ABLE account in 2026, and Medicaid marked as available, since SSI recipients are one of the groups federal law requires Medicaid to cover. The tool does not model trust distributions. Those have to respect SSI's $2,000 resource limit for an individual and its income rules: when a trust pays a provider directly for something other than food or shelter, such as a phone or medical bill, SSA does not count it as income; cash handed to the beneficiary is unearned income; and paying for shelter counts as in-kind support and maintenance (ISM), which can reduce the SSI check. Since September 30, 2024, food no longer counts as ISM.

Overfunding a first-party SNT while ignoring its Medicaid payback obligation is a frequent and costly error, as is structuring distributions that end up counted as ISM. Because these rules are intricate and individual circumstances vary, it is wise to work with a Certified Elder Law Attorney or Special Needs Planner before acting. SNT distributions work best when directed toward what government benefits do not cover, such as therapies, educational expenses, and other improvements to quality of life.

Example: What a Trust Can Pay Without Cutting SSI

  1. 1 Input: pick any disability type. The calculator shows SSI of $994 a month, $994 × 12 = $11,928 a year, and a 2026 ABLE contribution limit of $20,000.
  2. 2 The beneficiary's third-party SNT pays a physical therapist $2,400 directly. A payment to a provider for something other than food or shelter is not income for SSI, so the $994 check is unchanged.
  3. 3 If the trust instead handed the beneficiary $2,400 in cash, SSA would count it as unearned income: $2,400 less the $20 general exclusion is $2,380, more than the $994 benefit, so it would wipe out one month's SSI payment.
  4. 4 If the trust paid the beneficiary's rent, that would count as in-kind support and maintenance and reduce the check. Groceries paid by the trust no longer reduce SSI, because food was dropped from ISM on September 30, 2024.

Frequently Asked Questions

How much money should a special needs trust hold?
The amount depends on the individual's lifetime care needs. There is no upper limit on what a properly drafted third-party trust can hold; the aim is to cover supplemental needs such as therapies, personal care and recreation for the beneficiary's lifetime. Costs vary greatly based on the level of support required.
Does a special needs trust affect government benefits?
A properly structured third-party special needs trust does not count as a resource for SSI or Medicaid eligibility. The trust must be irrevocable, managed by a trustee, and used only for supplemental needs not covered by government programs.
What can a special needs trust pay for?
A special needs trust can cover supplemental needs like therapies, education, recreation, personal care attendants, transportation, technology, home modifications, and vacations. Paying for shelter, such as rent or a mortgage, counts as in-kind support and maintenance and can reduce SSI benefits; since September 30, 2024, food paid for by the trust no longer does.
