Do You Need an EIN for an Income-Only Trust in Arizona?
AHCCCS's policy is silent on tax-ID treatment for an Income-Only Trust -- none of EPM 803-A, EPM 803-C, DE-819, or the Trusts and ALTCS Eligibility Quick Reference Guide mention an EIN. DE-819 only requires that "a bank account must be set up that is titled to the trust and opened with a $0.00 balance." As a trust funded solely by the customer's own income, an Income-Only Trust is commonly opened using the beneficiary's Social Security number, consistent with how most 42 U.S.C. § 1396p(d)(4)(B) grantor trusts are banked nationally -- but this is ultimately a bank and tax question AHCCCS's own policy doesn't answer either way. Confirm titling with your attorney and the bank. That is the rule for an Arizona Qualified Income Trust. The question comes up most often at the bank, where staff may ask for an EIN out of habit. Below is what applies in Arizona and what to do if a branch's requirement differs from what AHCCCS publishes. This guide is informational only and is not legal or tax advice; for your specific situation, consult a qualified professional.
What usually happens
Arizona doesn't publish a fill-in form, so the trust has to be drafted to AHCCCS's requirements, and an elder-law attorney quotes $1,000–$2,500 to research and draft it. Once it's signed, you take it to the bank, where the branch has never opened one of these and says no.
Meanwhile the month is running out. In Arizona, coverage can't start before the month the trust is funded, so a month that slips is another month of private-pay nursing care at $7,604–$10,494.
This applies when the person who needs care has gross monthly income over Arizona's income cap of $2,982, whether you're their child, their spouse, or a professional helping them.

Why the bank may still ask for one
Even though AHCCCS does not require it, branch staff often ask for an EIN out of habit, because most trusts they open need a separate tax ID. If that happens, keep to how the account is titled under AHCCCS's guidance, and ask for the bank's trust department if the first person can't help.
Either way, the account is an ordinary bank account
Whether or not an EIN is involved, an Arizona Miller Trust account is a plain dedicated checking account titled to the trust — not a special product. What trips families up is rarely the tax ID; it is the branch's unfamiliarity with the account type. Knowing the answer before you go keeps the EIN question from turning into a wasted trip.
The EIN question almost always surfaces at the counter. See what to say at the bank in Arizona for the other refusals families hit, and the full step-by-step setup.
