New Mexico Special Needs Trust Rules (2026) | Complete State Guide

1. 1. New Mexico eliminated its DD Waiver waitlist — apply now.
   This is the biggest change in a decade. Between 2021 and 2025, New Mexico moved over 3,200 people off what was once a 10+ year waitlist. Over 8,500 people now receive DD Waiver or Mi Via services. There’s no longer a multi-year wait — applicants are enrolled monthly as they apply. Apply through the Health Care Authority even if you don’t need services yet.
2. 2. New Mexico is a community property state — your spouse’s consent matters.
   Property acquired during marriage belongs equally to both spouses under NMSA 40-3-8. Funding a trust with community assets without your spouse’s knowledge could be challenged. Separate property (inheritances, pre-marriage assets) can be kept separate, but it’s presumed community unless you prove otherwise. Your SNT attorney must understand community property rules.
3. 3. New Mexico has no state estate or inheritance tax.
   Only the federal estate tax applies, and the 2026 exemption is $15 million per person ($30 million for married couples). This means for most families, your estate plan is about protecting your child’s benefits and ensuring quality of life — not about estate tax avoidance. But a trust is still essential because even a modest inheritance can disqualify your child from Medicaid and SSI.
4. 4. Medicaid can only recover from probate assets — but the rules depend on which type of trust you have.
   (For third-party SNTs) — Good news. New Mexico limits Medicaid estate recovery to property that passes through probate (NMAC 8.200.430). A properly funded irrevocable third-party trust avoids probate entirely — Medicaid can never touch it.
   
   (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 New Mexico 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.
5. 5. Trust income is taxed up to 5.9% by New Mexico.
   Unlike Florida or Texas, New Mexico does tax trust income. The state income tax rates for 2025 range from 1.5% to 5.9%. Trust income that stays in the trust is typically taxed at the trust level, which hits the highest bracket quickly (trusts have compressed brackets). Distributions to the beneficiary are taxed at their rate instead. Your trustee and tax preparer should coordinate to minimize this.
6. 6. SSI approval automatically qualifies your child for Medicaid.
   New Mexico is a Section 1634 state — no separate Medicaid application needed once SSI is approved. But the SSI asset limit is just $2,000. Without a trust, even a small inheritance or settlement pushes your child over the limit and cuts off both SSI and Medicaid. This is why a trust isn’t optional — it’s essential.
7. 7. Existing trusts can be converted to special needs trusts without going to court.
   New Mexico adopted the Uniform Trust Decanting Act in 2017 (NMSA 46-12-101 through 46-12-129). Section 46-12-113 specifically addresses trusts for beneficiaries with disabilities — a trustee can restructure an existing trust into a special needs trust to protect benefits. This is a powerful tool if a grandparent left money in a regular trust.
8. 8. 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. This is a federal rule that applies everywhere, but New Mexico families should make sure their trustee knows about it — it opens up real flexibility in how trust funds support daily life.
9. 9. 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 in 2026). That’s the tradeoff, and it’s worth understanding before your trustee starts writing checks. Many families decide the housing benefit is worth the SSI reduction, but it should be a deliberate choice.
10. 10. New Mexico has 23 tribal nations — and special Medicaid rules for tribal members.
    If your family is Native American, Medicaid works differently. Tribal members are exempt from mandatory managed care enrollment — you can choose Fee-for-Service Medicaid or voluntarily join a Turquoise Care MCO. Services at IHS and tribal facilities are reimbursed at 100% federal match. And as of October 2024, New Mexico is one of the first four states where Medicaid covers traditional healing practices.
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), New Mexico law (N.M. Stat. Ann. § 46A-8-813) 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. Not accounting for community property when funding the trust. In New Mexico, property acquired during marriage belongs equally to both spouses. If you fund a trust with community assets without your spouse’s agreement, it can be challenged. Separate property (inheritances, gifts, pre-marriage assets) can go directly into the trust, but everything else needs both spouses on the same page. Your attorney should address this explicitly.
2. 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. New Mexico’s $2,000 asset limit means even a modest inheritance is devastating. Every dollar meant for your child needs to go through the trust, not to them.
3. Assuming the DD Waiver still has a multi-year waitlist. It doesn’t. New Mexico eliminated the waitlist between 2021 and 2025. Over 8,500 people now receive services. If you haven’t applied because you assumed the wait was hopeless, apply today through the Health Care Authority.
4. 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. In New Mexico, this means being especially careful about community property designation when transferring assets.
5. Not using NM STABLE’s tax deduction. New Mexico is one of the states that offers a state income tax deduction for ABLE account contributions. If your loved one qualifies, your attorney should be moving money from the trust into an NM STABLE account (up to $20,000/year) to take advantage of both the tax deduction and the simpler management. But understand that Medicaid payback does apply to NM STABLE at death.
6. Not planning for potential federal Medicaid cuts. The federal “Big Beautiful Bill” signed in 2025 introduces work requirements by January 2027 and rate cuts by 2028. New Mexico created a $2 billion trust fund to buffer the impact, but families should be proactive. Make sure your trust and benefit plan can withstand policy changes.
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.

Important: Unlike some states, New Mexico’s ABLE accounts are subject to Medicaid payback after the beneficiary’s death. The state can file a claim for Medicaid costs paid after the ABLE account was established. Factor this into your planning — ABLE is still valuable for its tax benefits and simplicity, but it’s not a way to avoid Medicaid recovery.

Beyond the Trust: Other New Mexico Planning Steps

Guardianship & Conservatorship: New Mexico uses both terms — a guardian makes personal and healthcare decisions, while a conservator manages finances (NMSA 45-5-301 and 45-5-401). Limited guardianship is available, and as of April 2025, the new Supported Decision-Making Act (SB 535) provides a less restrictive alternative that preserves your child’s rights.

Medicaid Waivers: New Mexico’s DD Waiver waitlist is eliminated — apply now. Mi Via offers self-directed services. The Medically Fragile Waiver uses only the child’s income (not parents’). Learn about waivers →
