A medical trust is an irrevocable legal arrangement that holds assets on behalf of someone who needs healthcare or long-term care, structured so those assets don’t disqualify the person from Medicaid or other government benefits. Families usually set one up when they’re planning for nursing home costs or protecting a disabled relative’s eligibility for public assistance. The specifics shift depending on which type of trust you use, but the core mechanic is always the same: move assets out of your name, under specific federal rules, so Medicaid doesn’t count them against you.
What the Term Actually Covers
“Medical trust” isn’t a single legal term you’ll find in any statute. It’s an umbrella label for several distinct trust types, all designed around healthcare eligibility or medical expenses: Medicaid Asset Protection Trusts, Special Needs Trusts, pooled trusts, and Miller Trusts. Each serves a different purpose and follows different rules, but they share the same basic structure. A grantor creates and funds the trust, a trustee manages the assets according to the trust document, and a beneficiary receives the benefit of those assets for healthcare-related needs.
What ties them together is their relationship with Medicaid. Medicaid is the primary payer for long-term care in the United States, and it’s means-tested. In most states, an individual applying for long-term care coverage can have no more than $2,000 in countable assets. That threshold pushes many families into a difficult choice: spend everything down, or find a legally compliant way to protect some wealth while still qualifying for benefits.
Why the Trust Has to Be Irrevocable
This is where most planning mistakes happen. Federal law draws a hard line between revocable and irrevocable trusts for Medicaid purposes. A revocable trust, the kind commonly used in basic estate planning, is treated as still belonging to you. Medicaid counts the entire corpus as an available resource, and any distributions count as your income. A revocable living trust does nothing to protect assets from Medicaid.
An irrevocable trust works differently. Once you transfer assets into it, you give up the ability to revoke the trust, change its terms, or direct distributions back to yourself. Under federal law, only the portions of an irrevocable trust from which no payment could be made to you under any circumstances are treated as no longer being your resource. If the trust gives the trustee any discretion to pay you, even in an emergency, Medicaid counts that portion as available to you.
Two consequences follow. The trust document’s exact language matters enormously, and the grantor should never serve as their own trustee. If you’re the trustee with the power to distribute assets to yourself, Medicaid will treat those assets as though you still own them.
The Four Main Types
The right trust depends on what problem you’re trying to solve: protecting assets before you need care, preserving benefits for a disabled person, or qualifying for Medicaid when your income is too high.
Medicaid Asset Protection Trusts
A Medicaid Asset Protection Trust (MAPT) is the tool most people think of when they hear “medical trust.” You transfer assets (cash, investments, a home) into an irrevocable trust, and once the look-back period passes, Medicaid no longer counts those assets when determining your eligibility. The trust is drafted so that no distributions can flow back to you, which is what makes the assets non-countable under federal law.
A common use is protecting a primary residence. The trust can be written so you keep the right to live in the home for your lifetime, even though the trust technically owns it. After the five-year look-back, the home is shielded from Medicaid estate recovery, the process by which states recoup the cost of care from your estate after death. Without the trust, your home could be subject to a Medicaid lien.
One limitation worth flagging: transferring retirement accounts like 401(k)s and IRAs into an irrevocable trust triggers immediate tax consequences, because the transfer is treated as a full distribution. For most people, the tax hit outweighs the Medicaid benefit.
Special Needs Trusts
A Special Needs Trust (SNT) lets a disabled person hold assets without losing eligibility for Supplemental Security Income or Medicaid. There are two varieties, and the distinction carries real financial weight.
A first-party SNT holds the disabled person’s own money, typically from a personal injury settlement, inheritance, or back-payment of benefits. Federal law requires the beneficiary to be disabled and under age 65 when the trust is established, and it must be created by a parent, grandparent, legal guardian, or court. A 2016 change allows the individual to establish the trust themselves in some circumstances. The critical catch: when the beneficiary dies, the state gets reimbursed first, up to the total amount of Medicaid benefits paid on the person’s behalf. Only after that payback can anything remaining pass to other beneficiaries.
A third-party SNT holds money that was never the disabled person’s to begin with, such as gifts from parents, grandparents, or other family members. Because the funds never belonged to the beneficiary, there is no Medicaid payback requirement at death. The remaining assets pass to whomever the trust names. For families with the means to fund a trust from their own assets, a third-party SNT is almost always the better choice.
Both types supplement government benefits rather than replace them. The trust can pay for things Medicaid and SSI don’t cover: medical costs beyond what the programs provide, transportation, education, personal care items, entertainment. Distributions paid directly to a third party for anything other than food and shelter generally don’t reduce SSI benefits.
Pooled Special Needs Trusts
A pooled trust operates under the same federal exception as a standard SNT but with a different structure. It must be established and managed by a nonprofit organization, which maintains a separate account for each beneficiary while pooling the funds together for investment purposes. The nonprofit handles accounting, distributions, and investment management, which makes pooled trusts accessible to people who don’t have a family member willing to serve as trustee or enough assets to justify hiring a professional one.
Pooled trusts also carry an important advantage: no age restriction. While a first-party SNT requires the beneficiary to be under 65, a pooled trust can be set up for a disabled individual at any age. When the beneficiary dies, any funds not retained by the nonprofit must be used to reimburse the state for Medicaid benefits paid.
Miller Trusts (Qualified Income Trusts)
Miller Trusts solve a different problem entirely. In states that use an income cap for Medicaid long-term care eligibility, you’re disqualified if your monthly income exceeds that cap, even by a dollar, regardless of how high your care costs run. The cap is set at 300% of the SSI federal benefit rate. For 2026, that works out to $2,982 per month.
A Miller Trust lets you deposit your income into the trust each month, which removes it from Medicaid’s income calculation. The trustee then distributes the funds under specific rules: a personal needs allowance for the beneficiary, any spousal allowance, and the remaining balance applied to the cost of care. Any funds left in the trust when the beneficiary dies must be paid to the state to reimburse Medicaid.
Unlike the other trusts, a Miller Trust doesn’t protect assets. It’s purely an income-routing mechanism. It’s irrevocable, but because the money flows through the trust and is spent on care each month, little or nothing usually accumulates.
Choosing a Trustee
Who runs the trust matters more than most families realize. The trustee controls every distribution, handles paperwork, files tax returns, and makes judgment calls about which expenses qualify. For any trust designed to preserve Medicaid eligibility, the grantor and the grantor’s spouse should not serve as trustee. If either keeps control over distributions, Medicaid can treat the trust assets as available resources, defeating the whole point.
Families typically weigh a trusted individual (an adult child, sibling, or friend) against a professional corporate trustee (a bank or trust company). Family trustees know the beneficiary’s needs personally and don’t charge fees, but they may lack experience with trust accounting, make emotional distribution decisions, or become unavailable due to their own health or death. Serving as trustee can also strain the relationship, especially when the trustee has to refuse a request.
Professional trustees bring institutional experience, continuity, and impartial decision-making. They’re also expensive. Annual fees typically run between 0.5% and 2% of trust assets, often with a minimum annual charge regardless of the trust’s size. Some corporate trustees decline to manage trusts that hold real estate or require hands-on special needs decisions. A middle option is naming a family member and a professional as co-trustees, splitting the personal knowledge and the administrative load. Whatever you decide, the trust document should include a succession plan for replacing the trustee if they can no longer serve.
The Five-Year Look-Back
Transferring assets into an irrevocable trust doesn’t give you instant Medicaid protection. Federal law imposes a 60-month look-back period. When you apply for Medicaid long-term care benefits, the state examines every asset transfer you made in the previous five years. Any transfer made for less than fair market value during that window triggers a penalty period, a stretch of time during which you’re ineligible for Medicaid coverage of nursing facility services.
The penalty isn’t a flat five years. It’s calculated by dividing the total value of the transferred assets by the average monthly cost of nursing home care in your state. If you transferred $150,000 and the average monthly nursing home cost in your state is $12,500, the penalty period is 12 months. And it doesn’t start running when you made the transfer. It starts when you apply for Medicaid and would otherwise be eligible, which means you could face months with no coverage and no way to pay for care out of assets you no longer own.
Timing is everything. Fund the trust at least five years before you need Medicaid and the transfers fall outside the look-back entirely. Wait too long, and the trust can leave you worse off. For people already in or near a health crisis, the look-back severely limits what asset protection is still possible.
What Happens at Death: Estate Recovery and Payback
Even after someone qualifies for Medicaid and receives benefits, the financial relationship doesn’t end at death. Federal law requires every state to operate a Medicaid estate recovery program. For beneficiaries age 55 and older, the state must seek reimbursement from the person’s estate for nursing facility services, home and community-based services, and related hospital and prescription drug costs.
How this plays out depends on the trust:
- MAPTs: once the look-back has passed, assets inside the trust are not part of your estate for Medicaid recovery purposes. This is the primary payoff for creating the trust early.
- First-party SNTs: the state must be reimbursed first from any remaining trust assets when the beneficiary dies, up to the total amount of Medicaid assistance paid. The state has priority over other debts, funeral expenses, and remaining beneficiaries.
- Third-party SNTs: because the funds never belonged to the beneficiary, there is no payback obligation. Remaining assets pass to the trust’s named beneficiaries.
- Pooled trusts: any amounts not retained by the nonprofit must reimburse the state for Medicaid benefits paid.
- Miller Trusts: any balance remaining at death goes to the state, though in practice little accumulates.
The payback requirement on first-party trusts catches many families off guard. If a disabled child receives a $500,000 settlement at age 20 and lives on Medicaid for decades, the state’s reimbursement claim can consume everything left in the trust. Understanding this before choosing between a first-party and third-party SNT can save a family hundreds of thousands of dollars.
Setting One Up: Cost, Process, and Taxes
Creating a medical trust is not a DIY project. The trust document has to satisfy specific federal requirements to achieve Medicaid compliance, and a single drafting error (giving the trustee too much discretion, omitting required payback language, failing to restrict distributions properly) can make the entire trust worthless for eligibility purposes. You need an attorney who specializes in elder law or special needs planning, not a general-practice lawyer who occasionally handles trusts.
The process itself is straightforward. The attorney drafts the trust document around your goals, names the trustee and beneficiaries, and includes all required provisions for the type of trust you’re creating. You sign the document, then fund the trust by transferring ownership of assets. That means retitling bank accounts, deeding real property, and reassigning investment accounts from your name into the trust’s name. Funding is the step families most often delay or do incompletely, and an unfunded trust protects nothing.
Attorney fees for drafting a Medicaid-compliant trust typically run from $1,000 to $5,000 or more, depending on complexity and location. A professional trustee adds ongoing annual fees of roughly 0.5% to 2% of trust assets. These costs are real, but they’re small against what’s at stake. Average nursing home costs run over $9,000 per month nationally, and Medicaid estate recovery can claim a family home.
An irrevocable medical trust is also a separate legal entity for tax purposes. It needs its own Employer Identification Number from the IRS, which you can apply for online at no cost. Miller Trusts are the exception; as grantor trusts, they use the beneficiary’s Social Security number. If the trust earns $600 or more in gross income during the tax year, the trustee must file Form 1041, the fiduciary income tax return. Irrevocable trusts hit the highest federal income tax brackets at very low income levels compared to individuals, so a trust-savvy accountant is worth the cost. Mistakes on Form 1041 can create problems with both the IRS and the Medicaid agency.
The single most important variable is timing. Fund the trust at least five years before you anticipate needing Medicaid, so the assets clear the look-back completely. For Special Needs Trusts, the timeline is different: a first-party SNT is often established when a settlement or inheritance arrives, and a third-party SNT can be created at any time by family members planning ahead. In every case, starting earlier gives you more flexibility and better outcomes.
