Illinois Special Needs Trust Rules (2026) | Complete State Guide

1. 1. Illinois state law explicitly protects third-party trusts from government claims.
   This is a big deal. The Illinois Trust Code (760 ILCS 3/509) says a discretionary trust for a person with a disability shall not be liable to reimburse the state for services. As long as distributions are made for your child’s benefit — not directly to them — the trust is shielded. This is extra protection on top of what federal law provides.
2. 2. Illinois doesn’t have an income cutoff for Medicaid — no second trust needed.
   Many states have hard income caps where earning $1 too much disqualifies you from Medicaid until you set up a separate trust. Illinois doesn’t do that. Instead, you “spend down” excess income on medical costs. That means one trust is usually enough.
3. 3. Medicaid estate recovery is limited — but the rules depend on which type of trust you have.
   (For third-party SNTs) — Since 2022, Illinois can’t recover the first $25,000 of a deceased person’s estate, and the state can no longer place new liens on your home. Recovery is primarily from the probate estate, so assets in a properly structured third-party trust are generally safe.
   
   (For first-party SNTs) — Different rule. Because this trust was funded with your family member’s own money, federal law (42 USC §1396p) requires that any funds left in the trust when they pass away must first reimburse Illinois Medicaid for benefits paid during their lifetime. This isn’t estate recovery — it’s a payback clause built into the trust itself. Whatever remains after Medicaid is repaid goes to the family. This is the tradeoff for protecting benefits during your family member’s life.
4. 4. Illinois taxes trust income at 6.45%.
   That’s the state income tax (4.95%) plus a replacement tax (1.5%) that applies to trusts. A typical family trust with $200K–$500K in assets might generate $10,000–$20,000 in annual investment income, meaning $645–$1,290 in state tax alone — on top of federal tax. Larger trusts pay proportionally more. It’s worth knowing because it affects how much the trust actually keeps.
5. 5. Existing trusts can be converted to special needs trusts — even without creating a new one.
   If a grandparent left money in a regular trust and your child needs benefits, a fiduciary can restructure it into an SNT using the Illinois Trust Code’s decanting provisions. Illinois even allows amending the original trust directly — no second trust required.
6. 6. ABLE contributions are tax-deductible in Illinois — but only through the state program.
   You can deduct up to $10,000 per individual ($20,000 joint) from your Illinois taxes for contributions to an IL ABLE account. But the deduction only applies to the Illinois program — contributing to another state’s ABLE plan doesn’t count.
7. 7. The trust can pay for groceries without reducing your child’s SSI.
   This changed in October 2024. Before that, buying food with trust money cut the SSI check. It doesn’t anymore.
8. 8. The trust paying for housing DOES still reduce SSI.
   Rent, mortgage, utilities — if the trust pays those, the SSI check goes down (up to about $351/month). That’s the tradeoff, and it’s worth understanding before your trustee starts writing checks.
9. 9. Illinois’s Medicaid asset limit is $17,500 — much higher than most states.
   Illinois raised this from $2,000 in 2023. If your child’s countable assets are below $17,500, they may qualify for Medicaid without a trust. For amounts above that, the trust becomes essential.
10. 10. Illinois courts must consider limited guardianship before full guardianship.
    Your child keeps every right that isn’t specifically given to the guardian. Since 2022, Illinois also has a supported decision-making law — a formal alternative where your child retains all legal authority while a supporter helps them understand decisions.
11. 11. The person managing the trust (the “trustee”) has to account for every dollar — no matter what type of trust you set up.
    Whether you created a third-party trust (funded with your money) or your child has a first-party trust (funded with theirs), Illinois law (760 ILCS 3/813) gives your family the right to request a full accounting of how trust money is being spent. This isn’t optional — it’s the law. If a bank, attorney, or family member is serving as trustee and won’t show you where the money is going, that’s a red flag.

From my 15+ years helping families (including my own):

1. Leaving money directly to your disabled child. A well-meaning grandparent leaves $50,000 in a will to your child — and destroys their SSI and Medicaid. The Illinois State Bar Association says it plainly: every will needs a paragraph directing assets through a special needs trust. Every dollar meant for your child needs to go through the trust, not to them.
2. Creating the trust but never funding it. A trust sitting in a drawer with no assets in it protects nothing. The trust only works if you actually move assets into it — bank accounts, life insurance beneficiary designations, your will.
3. Giving your child cash, checks, or gift cards from the trust. SSA counts those as income and countable resources. The entire point of the trust is that the trustee controls distributions and pays vendors directly. Hand your child a $200 check and it could push them over the $2,000 SSI asset limit.
4. Never updating the trust as rules change. The rules around food purchases changed in 2024. ABLE account eligibility expanded in 2026. Illinois adopted an entirely new Trust Code in 2020 with stronger protections. A trust drafted five years ago may already be outdated.
5. Not realizing first-party trusts pay Medicaid back at death. If the trust was funded with your child’s own money (from a settlement, inheritance, or work), Illinois Medicaid gets reimbursed from whatever is left when your child dies. Families are often shocked by the amount. Moving money from a first-party SNT into an ABLE account (up to $20,000/year) is a legitimate strategy to reduce that exposure — talk to your attorney about it.
6. Waiting until age 65 to set up a pooled trust. Illinois’s SMART Act treats transfers to a pooled trust for someone 65 or older as a penalty-triggering gift. Set it up before 65 if there’s any chance your child will need one. After 65, options are limited.
7. Waiting until after you die to set up the trust. If you’re reading this page, do it now. Not next year. Your estate plan, your will, your life insurance beneficiary designations — all of it needs to point to the trust before something happens to you.
