A non-revocable trust, more commonly called an irrevocable trust, is a legal arrangement where the person who creates the trust permanently gives up ownership and control of the assets placed inside it. Once the trust is established, the creator cannot change its terms, take back the assets, or shut it down without permission from the beneficiaries or a court order. This permanence is the defining feature, and it’s also the reason irrevocable trusts offer powerful tax and asset protection benefits that revocable trusts do not.
How an Irrevocable Trust Works
Three roles make an irrevocable trust function. The grantor is the person who creates the trust and transfers assets into it. The trustee is the person or institution that takes legal ownership of those assets and manages them according to the trust’s written instructions. The beneficiary is whoever the trust is designed to benefit, whether that’s a spouse, children, grandchildren, or a charity.
When you, as the grantor, move assets into an irrevocable trust, you are legally giving up ownership. You cannot access the assets, manage them directly, or redirect who receives them. The trustee holds a fiduciary duty, meaning they are legally obligated to manage the trust assets in the best interest of the beneficiaries, not themselves. The trustee distributes income or principal to the beneficiaries based on whatever guidelines the trust document spells out.
This separation of ownership is what makes the trust effective. Because you no longer own the assets, they generally aren’t counted as part of your estate for tax purposes, and creditors typically can’t reach them in a lawsuit the way they could with assets you personally own or hold in a revocable trust.
Why People Create Irrevocable Trusts
The trade-off of giving up control is significant, so irrevocable trusts are typically used when the benefits clearly justify the permanence. The most common reasons fall into three categories.
Reducing estate taxes: The federal estate tax applies when a deceased person’s total estate exceeds a certain threshold. For 2026, that filing threshold is $15,000,000. Assets inside an irrevocable trust are not part of the grantor’s taxable estate, which can substantially lower or eliminate the estate tax bill. For wealthy families, this is often the primary motivation. One important detail: the grantor is typically expected to pay income taxes generated by trust assets out of pocket, without being reimbursed by the trust. Getting reimbursed can void the tax benefits.
Protecting assets from creditors: Because the grantor no longer legally owns assets in an irrevocable trust, those assets are generally shielded from lawsuits and creditor claims against the grantor. This protection can also extend to the beneficiaries in certain trust structures. A revocable trust, by contrast, offers no creditor protection because the grantor still controls the assets.
Qualifying for Medicaid: Long-term care is expensive, and Medicaid requires applicants to have very limited assets. A Medicaid Asset Protection Trust, a specific type of irrevocable trust, lets you move assets out of your name so they aren’t counted when Medicaid evaluates your eligibility. The assets also aren’t included in Medicaid estate recovery calculations after your death. However, timing matters enormously here, which leads to the lookback rule.
The Medicaid Lookback Period
Medicaid doesn’t just check what you own today. The program reviews whether you transferred, gifted, or sold assets below fair market value during a lookback window. In most states, that window is five years. If you moved assets into an irrevocable trust within that period, Medicaid can impose a penalty that delays your eligibility for long-term care benefits.
The practical takeaway: you need to establish a Medicaid Asset Protection Trust at least five years before you expect to need long-term care. Once assets have been in the trust past that lookback period, they generally won’t trigger penalties or affect your eligibility. Planning early is essential because you can’t predict a health crisis, and creating the trust after you already need care defeats the purpose.
Common Types of Irrevocable Trusts
Irrevocable trusts come in several specialized forms, each designed for a specific goal.
- Irrevocable Life Insurance Trust (ILIT): Holds a life insurance policy outside your estate. Without this trust, the death benefit of a policy you own is included in your taxable estate. An ILIT removes it, which can save beneficiaries hundreds of thousands in estate taxes on large policies.
- Spousal Lifetime Access Trust (SLAT): Lets one spouse transfer assets out of their estate while naming the other spouse as a beneficiary. This allows the couple to still indirectly access the money during their lifetimes while locking in estate tax savings.
- Medicaid Asset Protection Trust (MAPT): Specifically structured to protect assets while allowing the grantor to eventually qualify for Medicaid long-term care benefits. The grantor cannot be a beneficiary of the trust’s principal.
- Charitable Remainder Trust: Provides income to the grantor or other beneficiaries for a set period, then donates the remaining assets to a charity. This generates a partial tax deduction when the trust is funded.
Can You Change an Irrevocable Trust?
“Irrevocable” sounds absolute, but there are a few narrow legal paths to modify one. None of them are simple, and all have limitations.
The most straightforward option is a settlement agreement. If the trustee and all beneficiaries agree, they can petition to change certain administrative provisions of the trust, such as investment rules or trustee succession. However, settlement agreements generally cannot change who benefits from the trust or how much they receive.
Decanting is a more powerful tool available in many states. It allows a trustee to essentially pour the assets from the existing trust into a new trust with updated terms. The trustee can do this without beneficiary consent in some cases, but the changes must stay within limits set by state law. Not every state permits decanting, and the rules vary considerably.
Some trusts include a trust protector, an independent third party named in the original document who has authority to make specific changes. The scope of a trust protector’s power depends entirely on what the trust document grants them. Similarly, some trusts give a beneficiary a power of appointment, allowing that person to redirect how trust assets are distributed among a defined group, like the grantor’s descendants. The beneficiary exercising this power can specify whether assets go outright or remain in trust under different terms.
A court can also modify or terminate an irrevocable trust, but courts typically require a showing that circumstances have changed in ways the grantor couldn’t have anticipated, or that the trust’s purpose has become impossible to fulfill.
What It Costs to Set Up
Creating an irrevocable trust is more complex than drafting a simple will. Attorney fees for setting one up typically range from $2,000 to $10,000 or more, depending on the complexity of the trust, the assets involved, and the type of trust being created. A straightforward MAPT will generally cost less than a SLAT or a trust holding business interests.
Beyond the initial setup, irrevocable trusts have ongoing costs. The trust may need to file its own tax return each year (IRS Form 1041). If you hire a professional trustee, such as a bank or trust company, expect annual management fees that are often a percentage of the trust’s assets, commonly ranging from 0.5% to 1.5%. Even with an individual trustee, there are accounting and tax preparation costs to consider.
Who Should Consider One
Irrevocable trusts make sense for people in specific situations. If your estate is large enough that it may exceed the federal estate tax threshold, an irrevocable trust can shelter assets from that tax. If you’re planning ahead for potential long-term care needs and want to protect your home or savings from Medicaid spend-down requirements, a MAPT created well in advance of needing care is worth exploring. If you own a business or have significant assets and are concerned about litigation risk, the creditor protection of an irrevocable trust is a meaningful benefit.
For someone with a modest estate and no particular creditor concerns, a revocable trust or a well-drafted will may accomplish everything they need without the permanence and complexity of an irrevocable structure. The key question is whether the tax savings, asset protection, or Medicaid planning benefits are valuable enough to justify permanently giving up control of those assets.
