Do You Need an EIN for a Miller Trust in New Mexico?

New Mexico's Income Diversion Trust regulation (8.281.510 NMAC, read in full) does not address EIN-versus-SSN treatment anywhere -- a genuine, confirmed silence, not an oversight in this guide's research. A trust funded only by the beneficiary's own income is commonly opened using the beneficiary's own Social Security number, consistent with how similar Medicaid income trusts are banked nationally, but this is not confirmed by New Mexico's own policy. If a branch asks for an EIN out of habit, confirm the account titling with your attorney and the bank. That is the rule for a New Mexico 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 New Mexico and what to do if a branch's requirement differs from what HCA publishes. This guide is informational only and is not legal or tax advice; for your specific situation, consult a qualified professional.

Why the bank may still ask for one

Even though HCA 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 HCA'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, a New Mexico 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 New Mexico for the other refusals families hit, and the full step-by-step setup.
