An irrevocable trust is a trust the creator (the "grantor") cannot change or revoke after creating the trust. Creators give up control of the assets they put into irrevocable trusts. For this reason, an irrevocable trust can reduce estate taxes. It can also help avoid the probate process when the grantor dies.
Though there are exceptions, there’s no way to change an irrevocable trust once the assets are in the trust. Either all beneficiaries of the trust must agree to the change, or a court must order a change .
Irrevocable trusts vs. revocable trusts
The main difference between irrevocable trusts and revocable or living trusts is who has control of the assets in the trust. With an irrevocable trust, the grantor forfeits control of the assets once they go into the trust; with a revocable trust, the grantor controls the trust assets until death. Both allow people to make arrangements ahead of time in case of incapacity, and both generally help keep financial affairs private.
Types of irrevocable trusts and how they work
There are many kinds of irrevocable trusts. Below are some examples. An estate planning attorney or a financial advisor can help you determine what works best for your situation and help you meet your estate planning goals.
- Grantor-retained annuity trusts (GRATs) and qualified personal residence trusts, or QPRTs. A GRAT is an irrevocable trust that allows the grantor to put certain assets in a temporary trust and freeze its value, removing additional appreciation from the grantor’s estate and giving it to heirs with minimal estate or gift tax liability. During the term of the GRAT, the trust pays an annuity to the grantor, so the assets in the GRAT are considered returned to the grantor .
- Generation-skipping trusts and dynasty trusts. These can shelter children or even multiple generations of heirs from estate tax. In a generation-skipping trust, for example, you transfer money to grandchildren or other people who are at least 37.5 years younger than you .
- Spendthrift trusts. When beneficiaries can’t make good financial decisions for themselves, the trustee of a spendthrift trust decides when and how the beneficiary is allowed to use the money.
- Special needs trusts. Also known as supplemental needs trusts, special needs trusts allow a person with functional needs to get financial support without negatively affecting any means-tested government benefits they’re receiving, such as Medicaid or Supplemental Security Income (SSI) .
- Charitable remainder trusts (CRTs), charitable lead trusts (CLTs) and pooled income trusts. Charitable trusts essentially leave any leftover trust assets to a charity of the grantor's choice.

How to set up an irrevocable trust
Here are the basic steps.
- The grantor establishes the trust.
- The grantor designates a third party to act as trustee and names beneficiaries.
- The grantor transfers assets into the trust. The grantor surrenders ownership rights and cedes control to the trustee. These assets are no longer part of the grantor’s taxable estate.

Benefits of irrevocable trusts
1. Potential estate tax savings
If your estate is likely subject to estate tax, figuring out ways to minimize or avoid the hefty tax burden can be enticing. For most people, this isn't a concern. The federal estate tax ranges from 18% to 40% and generally only applies to assets over $13.99 million in 2025 or $15 million in 2026. However, some states levy their own estate taxes and tax small estates. Also, the federal estate tax exemption could change or become lower over time, which is something to consider when planning for the future.
2. Potential protection from creditors
For those in occupations prone to lawsuits — such as attorneys, doctors and real estate developers — keeping personal assets out of the reach of creditors can help protect you and your heirs . Irrevocable asset protection trusts may do exactly this.
There are two varieties: domestic and foreign or offshore. Not all states allow domestic asset protection trusts, and foreign ones can be costly to administer. Furthermore, if a court determines that your asset protection trust was created with the intent to defraud creditors, you could face significant legal consequences and be forced to undo your asset transfer .

3. Can help retain qualification for certain government programs
To qualify for certain government programs, such as Medicaid, applicants often need to demonstrate that they have limited assets and income.
An asset protection trust removes assets from one’s estate, which can in turn make a person eligible for certain government programs.
However, there are many rules surrounding the use of asset protection trusts to reduce assets. For example, Medicaid has a "look-back" period of up to five years to check that no assets were given away during that time. Forming an asset-protection trust within that time frame may violate the look-back rule and make the applicant ineligible. An estate planning attorney can help shed more light on whether a Medicaid asset protection trust is feasible for you.

Downsides of an irrevocable trust
1. Loss of control over assets
No matter what reasons are prompting you to set up an irrevocable trust, you’ll need to get comfortable giving up ownership rights and control of your assets. It isn’t always easy to let go of assets you’ve worked hard to earn and accumulate over your lifetime.
2. Reliance on a trustee
It may be hard to find someone you’re aligned with and feel confident will make decisions in the best interest of the trust. Grantors can usually appoint a trust protector as an additional set of eyes to watch over the management of the trust. Trust protectors pay attention to regulations and laws to monitor if any changes will have an adverse impact on the trust. They can act as a mediator if beneficiaries disagree and can also replace the trustee if necessary. The grantor is able to prescribe what powers the trust protector has when drafting the trust document.
3. No beneficiary changes
Once trust assets are transferred into an irrevocable trust, the grantor cannot alter the terms of the trust. This means that the grantor cannot remove or change the beneficiaries named in the trust or regain control of any trust assets if fortunes change and those assets are needed down the road.
4. Complexity
Trust strategies are complex and can be hard to understand and administer. Hiring a financial advisor carries a cost as well, though it could be a drop in the bucket compared to the long-term benefits of the trust. But because your decisions are irrevocable, making sure you’re aware of all the details and corresponding implications is very important so that you don’t end up inadvertently doing something you wouldn’t have wanted to do.
