A Miller trust is a special trust used to route excess income so a person can qualify for certain Medicaid long-term care benefits.

"Special trust" matters because the money does not just sit in a regular bank account under the applicant's name. Income such as Social Security, a pension, or other monthly payments is deposited into the trust, and the trust is set up to follow Medicaid rules. "Route excess income" means the trust is used when someone's income is over the Medicaid limit even though they still cannot realistically afford nursing home or other long-term care costs. "Qualify" does not mean the income disappears; it means Medicaid counts it differently if the trust is drafted and funded correctly.

In practice, a Miller trust can be the difference between getting coverage and being denied for being a little over the income cap. The trust usually must be irrevocable, name a trustee, and state that Medicaid will be repaid from remaining funds at death. Mistakes in setup or deposits can delay benefits and create large unpaid care bills fast.

In Iowa, this tool comes up in Medicaid long-term care cases handled through Iowa Medicaid and the Iowa Department of Health and Human Services. The rules are technical, so timing, wording, and monthly funding all matter when an elder law or Medicaid planning issue turns into a benefits problem.
