Arizona ALTCS Qualified Income Trust (Miller Trust) Explained

Why Income Can Block ALTCS Even When a Young Adult Clearly Qualifies Medically

Arizona's Long Term Care System (ALTCS) funds the home and community-based services that many young adults with developmental disabilities depend on after leaving the school system — attendant care, habilitation, respite, and day programs coordinated through the Division of Developmental Disabilities (DDD). But ALTCS has a strict financial gate: for 2026, a single applicant's gross monthly income cannot exceed $2,982, which is 300% of the federal SSI benefit rate.

Most 18-year-olds transitioning out of special education fall well under that cap. The problem surfaces when a young adult receives Social Security Disability Insurance (SSDI) based on a parent's work record, combines SSI with part-time wages, or inherits a small annuity or pension. Once gross monthly income crosses $2,982 — even by a dollar — ALTCS denies the application on financial grounds, regardless of how severe the disability is or how clearly the applicant meets the clinical Pre-Admission Screening (PAS) threshold of 40 points.

The fix is a Qualified Income Trust, commonly called a Miller Trust. It is a mechanism Arizona recognizes for individuals whose income exceeds the cap but who otherwise meet every ALTCS requirement.

What a Miller Trust Actually Does

A Miller Trust is an irrevocable trust with a single, narrow purpose: it receives the applicant's excess income each month so that the income is handled under ALTCS's income rules rather than counted directly against the $2,982 threshold.

The trust does not shelter assets — the ALTCS countable asset limit remains $2,000 for a single applicant, and the trust's bank account balance must be spent down each month. The trust simply redirects income through a legally recognized channel. AHCCCS (Arizona's Medicaid agency) requires the trust to name the State of Arizona as the remainder beneficiary, meaning any funds left in the trust at the member's death go to AHCCCS to reimburse Medicaid costs, up to the amount the state spent on the individual's care.

How to Set Up the Trust Before the ALTCS Application

Timing matters. The QIT must be established and funded before ALTCS approves the application — not after. Families who apply for ALTCS first and then scramble to set up the trust risk a denial that delays services by months.

Step 1: Retain an attorney. Arizona does not provide a standardized Miller Trust template. The trust document must comply with AHCCCS policy and applicable Medicaid requirements, which means an elder law or special needs planning attorney should draft it. Ask the attorney about the drafting fee before proceeding.

Step 2: Open a dedicated bank account. The trust needs its own checking account, titled in the trust's name (e.g., "Miller Trust for [Name]"). No other funds can be commingled in this account.

Step 3: Route income through the trust. Each month, the applicant's income sources (SSI, SSDI, wages, annuities) must deposit directly into the trust account. The trustee then distributes funds according to AHCCCS rules — typically paying any required patient responsibility and making other permitted distributions toward the applicant's personal needs allowance.

Step 4: Submit the trust document with the ALTCS application. Include a copy of the executed trust, the bank account statement showing the trust account, and proof that income is being routed through it.

Trustee Responsibilities and Monthly Administration

The trustee — usually a parent or family member — has ongoing obligations:

• Deposit all countable income into the trust account each month
• Use trust funds for the member's allowable patient responsibility and other permitted distributions under AHCCCS rules
• Distribute the personal-needs allowance permitted under current ALTCS rules
• Keep the trust account balance as close to zero as possible at the end of each month
• Maintain bank statements and records for AHCCCS annual eligibility reviews

The trust cannot pay for anything beyond what AHCCCS rules allow. It is not a spending vehicle for the family — it is a pass-through that satisfies the income test.

Common Mistakes That Jeopardize ALTCS Eligibility

Failing to deposit income every month. If income bypasses the trust and goes into the member's personal bank account, AHCCCS can count that income against the $2,982 limit and redetermine eligibility. This is the most common compliance failure.

Commingling funds. The trust account must contain only the member's income. Depositing family contributions, gifts, or other funds into the trust account can invalidate it.

Not coordinating with the ABLE account. Families sometimes use an Arizona ABLE account (which can hold up to $100,000 without affecting the $2,000 asset limit) alongside the Miller Trust. This is allowed, but the trust and ABLE account have different rules; confirm any transfer with the trustee, an attorney, and AHCCCS.

Letting the trust accumulate a balance. The trust is designed to be spent down monthly. A growing balance signals noncompliance and can trigger an AHCCCS review.

How the Miller Trust Fits the Broader Transition Timeline

For most families navigating the transition from special education to adult services, the Miller Trust conversation comes up around the young adult's 18th birthday. That is when parental income deeming ends for SSI purposes, the young adult applies for SSI and, if eligible, may receive SSDI based on a parent's work record, and the family submits the ALTCS application with PAS documentation.

If the young adult's projected monthly income — from all sources combined — will exceed $2,982, the Miller Trust should be drafted and the bank account opened several months before the 18th birthday so everything is ready when the ALTCS packet goes in. Delaying the trust setup is the single most common reason families experience gaps in DDD-funded services during the transition from school to adult life.
