Miller Trust in New Mexico: Income Diversion Trust for Medicaid Eligibility

Your parent's gross monthly income is $3,200 — Social Security plus a small pension. That's $218 over New Mexico's Medicaid income cap of $2,982. Without an Income Diversion Trust, your parent is completely ineligible for Medicaid long-term care coverage, even though their medical expenses dwarf their income. The trust fixes this.

Why New Mexico Requires a Miller Trust

New Mexico is an "income-cap state." Unlike states with medically needy spend-down programs, New Mexico has a hard ceiling: if an applicant's gross monthly income exceeds $2,982 (300% of the federal SSI benefit rate for 2026), they cannot qualify for Medicaid institutional care or the Turquoise Care Community Benefit waiver — period.

The Income Diversion Trust, commonly called a Miller Trust, is the legal mechanism to get around this cap. By routing your parent's income through a properly structured trust, the income placed in the trust is excluded from the eligibility calculation.

How the Trust Works

The Miller Trust is a sole-benefit, irrevocable trust that operates as a pass-through account:

Step 1: Open a dedicated bank account in the trust's name. This account must be separate from all personal accounts. The trustee (usually an adult child) manages the account.

Step 2: Deposit all gross income into the trust account each month. Social Security, pension payments, retirement distributions — every income source must flow through the trust. Direct deposit is the most reliable method.

Step 3: Distribute funds according to the state budget. Each month, the trustee pays out from the trust in a specific order:

• $97 Personal Needs Allowance (the resident's spending money)
• Monthly health insurance premiums (Medicare Part B, supplemental coverage)
• Spousal maintenance allowance (if the community spouse qualifies — up to $4,066.50/month)
• The remaining balance goes to the care facility as the Patient Liability

Step 4: State payback provision. The trust document must include a clause directing that any funds remaining in the trust at the beneficiary's death are paid to the State of New Mexico up to the total amount of Medicaid benefits provided.

What the Trust Must Include

New Mexico's Income Support Division (ISD) reviews the trust document as part of the Medicaid application. The trust must meet specific requirements:

• Irrevocable — the trust cannot be modified or dissolved while the beneficiary is alive and receiving Medicaid
• Sole-benefit — the trust exists exclusively for the Medicaid applicant's benefit
• State payback clause — upon the beneficiary's death, remaining funds reimburse the state before any other distribution
• Funded only with the beneficiary's income — no other assets can be deposited into the trust account
• Established before the Medicaid application is approved — the trust must be in place and funded before coverage begins

Common Mistakes

Failing to deposit all income. If Social Security goes to a personal checking account while only the pension goes through the trust, the trust is non-compliant. Every dollar of gross income must be routed through the trust account.

Using a generic trust template. Miller Trusts have state-specific requirements. A trust document drafted for Arizona or Texas may not include New Mexico's required payback language or comply with ISD review standards. Use a New Mexico elder law attorney or a state-specific template.

Confusing the Miller Trust with a spend-down. The Miller Trust addresses the income cap only. If your parent also has countable assets exceeding the $2,000 individual limit, those assets must be spent down separately through legally compliant methods — paying off debts, purchasing exempt assets, prepaying irrevocable funeral contracts, or executing a personal care agreement.

Starting too late. The trust must be established and funded before Medicaid coverage can begin. If your parent is already in a nursing facility with a pending Medicaid application and no trust in place, every month of delay is a month without coverage.

When You Need an Attorney

A Miller Trust is a legal document that must be drafted correctly the first time. The cost of having an elder law attorney prepare the trust typically runs $500-$1,500 in New Mexico — far less than a single month of private-pay nursing home care ($9,125 average).

Situations that definitely need professional help:

• Income from multiple sources (Social Security, pension, rental income, annuities)
• A community spouse whose own income affects the maintenance allowance calculation
• Complex asset structures that require coordinated spend-down alongside the trust
• Prior gifts or transfers during the 60-month lookback period that may trigger penalties
