Miller Trust Arizona — How an Income-Only Trust Qualifies Your Parent for ALTCS

Your parent's Social Security and pension add up to $3,400 a month. Arizona's ALTCS income cap is $2,982. That $418 overage doesn't just reduce benefits — it makes them completely ineligible. Arizona is an income-cap state, meaning there is no option to "spend down" excess income on medical bills to qualify.

The solution is a Miller Trust, formally called an Income-Only Trust (IOT). It's not a loophole — it's a federally authorized legal instrument that Arizona explicitly recognizes for ALTCS eligibility.

How a Miller Trust Works

A Miller Trust is an irrevocable trust with one narrow purpose: receiving the applicant's income so it no longer counts against the ALTCS cap. Here's the structure:

• The trust account starts at $0. You open a dedicated bank account in the trust's name with a zero balance. No personal savings, gifts, or outside funds can ever be deposited — only the applicant's own income sources.
• Entire income sources are assigned. The applicant redirects specific income streams (Social Security, pension, annuity) into the trust account. Partial routing of a single source is not allowed — you assign the entire check or nothing.
• Voluntary deductions must stop. Before routing income into the trust, the applicant must cancel voluntary withholdings like union dues, optional tax withholdings, and third-party life insurance premiums from the assigned sources.
• Arizona is the remainder beneficiary. The trust document must name the State of Arizona as primary beneficiary. When the applicant dies, any balance in the trust account is paid back to the state up to the total Medicaid benefits received.

Setting Up the Trust Step by Step

1. Draft the trust document. The document must comply with AHCCCS trust policy (DE-819). It names the applicant as grantor, designates a trustee (typically the adult child), and includes the mandatory state payback provision. Many families use an elder law attorney, though Arizona also permits licensed legal document preparers for straightforward cases.

2. Open a dedicated bank account. Take the signed trust document to a bank and open a checking account titled in the trust's name — for example, "Jane Smith Income-Only Trust." The account must be separate from all personal accounts.

3. Redirect income sources. Contact Social Security, the pension administrator, and any other income source to redirect payments into the trust account. This must happen within the calendar month of the ALTCS application.

4. Submit the trust with the ALTCS application. Include a copy of the executed trust document and proof of the redirected income when filing the Combo Form DE-101/DE-202 or through the HEAplus portal.

What the Trustee Pays From the Trust Each Month

Once ALTCS approves the application, the trustee distributes the trust funds in a specific order each month:

1. Personal Needs Allowance: $149.10 — the member's spending money for personal items
2. Medicare premiums: Part B, Part D, and any Medigap supplement premiums
3. Community Spouse Monthly Income Allowance: If a spouse lives at home and their independent income falls below $2,705, the trustee diverts enough of the applicant's income to bring the spouse up to that floor (up to $4,066.50 with excess shelter costs)
4. Health insurance premiums: Any remaining medical coverage premiums
5. Share of Cost: The remainder goes to the care facility or home-care provider as the applicant's monthly patient liability

The Income Cap Nobody Mentions

There's a second ceiling families rarely learn about until it's too late. The total income routed through the Miller Trust cannot exceed the Private Pay Rate (PPR) for the county where the applicant lives. For 2026:

• Maricopa, Pima, and Pinal Counties: $8,666.72 per month
• All other Arizona counties: $8,132.22 per month

If the applicant's gross monthly income exceeds their county's PPR, the trustee must file a Policy Clarification Request (PCR) arguing undue hardship. This is rare — most applicants' income falls well below these thresholds — but families with multiple pensions or substantial retirement distributions should check before applying.

Common Mistakes That Invalidate a Miller Trust

• Depositing non-income funds. A single deposit of personal savings, a gift from a child, or a home sale proceeds into the trust account permanently disqualifies the trust under AHCCCS rules.
• Partial income routing. Splitting one Social Security check between the trust and a personal account violates the all-or-nothing assignment rule.
• Missing the payback clause. If the trust document doesn't name Arizona as remainder beneficiary, ALTCS will reject it.
• Setting up too late. The trust must be established and funded within the same calendar month as the ALTCS application. Backdating doesn't work.
