A revocable trust can be changed or canceled by its creator at any time, while an irrevocable trust generally cannot be altered once signed. Revocable trusts offer flexibility and probate avoidance, while irrevocable trusts trade away control for stronger asset protection and potential tax benefits.
Key Takeaways
- Revocable trusts stay under your control for life but offer little protection from your own creditors.
- Irrevocable trusts move assets out of your legal ownership, which is what gives them stronger protection.
- The Internal Revenue Service taxes a revocable trust's income to you personally under the grantor trust rules.
- Most people start with a revocable living trust and only move to irrevocable planning for specific goals like Medicaid or estate tax reduction.
What Is a Revocable Trust?
A revocable trust, sometimes called a revocable living trust, lets the person who creates it (the settlor) amend, restate, or fully revoke the trust at any time while alive and mentally competent. The settlor usually serves as the initial trustee and continues to use and control the trust property exactly as before. Because of this retained control, the settlor is treated as the owner of the trust assets for both legal and tax purposes.
What Is an Irrevocable Trust?
An irrevocable trust cannot be changed or canceled by the settlor once it is executed, except in narrow circumstances such as court modification or a mechanism the trust itself allows. Giving up this control is what separates an irrevocable trust from a revocable one, and it is also the source of its main benefits: assets inside an irrevocable trust are generally out of reach of the settlor's creditors and out of the settlor's taxable estate.
Revocable vs. Irrevocable Trust: Head-to-Head Comparison
- Control: Revocable, the settlor keeps full control and can change or end the trust. Irrevocable, the settlor gives up control once the trust is signed.
- Probate avoidance: Both types avoid probate for properly funded assets.
- Creditor protection: Revocable, little to no protection from the settlor's own creditors. Irrevocable, generally strong protection since the settlor no longer owns the assets.
- Tax treatment: Revocable, treated as a grantor trust, income reported on the settlor's personal return. Irrevocable, often a separate taxpayer with its own tax identification number, though some irrevocable trusts are still structured as grantor trusts.
- Flexibility to change beneficiaries or terms: Revocable, yes, at any time. Irrevocable, no, absent a court order or a specific power reserved in the trust.
- Common uses: Revocable, general probate avoidance and incapacity planning. Irrevocable, Medicaid planning, estate tax reduction, and asset protection from lawsuits.
Common Types of Irrevocable Trusts
Not all irrevocable trusts serve the same purpose, and the right structure depends entirely on the goal. An irrevocable life insurance trust, often called an ILIT, owns a life insurance policy so the death benefit stays outside the insured's taxable estate. A Medicaid asset protection trust holds assets like a home so they no longer count against Medicaid's resource limits after the required look-back period passes. A spousal lifetime access trust, or SLAT, lets one spouse set up an irrevocable trust for the other spouse's benefit while still removing the assets from the settlor's own estate.
- Irrevocable life insurance trust (ILIT): keeps life insurance proceeds out of the taxable estate.
- Medicaid asset protection trust: shields assets from Medicaid spend-down after the look-back period.
- Spousal lifetime access trust (SLAT): removes assets from the settlor's estate while a spouse retains indirect access.
- Special needs trust: preserves a disabled beneficiary's eligibility for means-tested government benefits.
Why Most People Start With a Revocable Trust
A revocable living trust is the more common starting point because it solves the two problems most families actually have: avoiding probate and planning for incapacity, without asking the settlor to give up anything during life. You keep full use of your home, bank accounts, and investments exactly as before, and you can update beneficiaries or terms whenever your situation changes, such as a marriage, divorce, or the birth of a child.
The tradeoff is that a revocable trust does nothing to shield assets from your own creditors or lawsuits, and it does not remove assets from your taxable estate, since you never gave up ownership in any meaningful legal sense. For most households below the federal estate tax exemption threshold, that tradeoff is a non-issue, which is why revocable trusts remain the default recommendation for general estate planning.
How Does the IRS Tax Each Type of Trust?
A revocable trust falls under the grantor trust rules, meaning the settlor reports the trust's income, deductions, and credits on their own personal tax return as if the trust did not exist for tax purposes. The grantor trust rules at 26 U.S.C. Section 671 set out this treatment. An irrevocable trust that is not structured as a grantor trust is typically its own taxpayer and needs its own employer identification number, which you can apply for directly through the IRS online EIN application.
Does State Law Change Which Trust You Should Use?
Every state recognizes both revocable and irrevocable trusts, but the exact rules for creating, funding, and administering a trust come from state trust law, not federal law. Details like whether a trust needs to be notarized, witnessed, or both vary by state, and a trust that is valid in one state should still be reviewed if you move, since execution requirements are not identical everywhere. If you are setting up a living trust in a specific state, see our state-by-state living trust guides for the exact statute your state requires.
Which One Actually Protects Your Assets?
Because a revocable trust leaves the settlor in full control, courts generally treat trust assets as reachable by the settlor's own creditors, the same as if the assets were held individually. An irrevocable trust removes that control, and with it removes the assets from the settlor's ownership, which is why it can shield property from future creditors or lawsuits. This same feature is why irrevocable trusts show up in Medicaid planning and special needs planning; see our guide on special needs trust basics for how that works for a beneficiary with a disability.
Which One Do You Need?
If your main goal is avoiding probate, keeping flexibility, and planning for incapacity, a revocable living trust is usually the right starting point. See what is a living trust for the basics and how to fund a trust for the practical steps. If your goal is Medicaid eligibility, reducing a taxable estate, or protecting assets from a lawsuit, an irrevocable trust designed for that specific purpose is worth discussing with an attorney, since these trusts are harder to unwind if drafted incorrectly.

Frequently Asked Questions
Can I convert a revocable trust into an irrevocable one?
Yes, many revocable trusts become irrevocable automatically upon the settlor's death, and some can be converted earlier if the trust terms allow it or a court approves the change.
Does an irrevocable trust always save on estate taxes?
Not automatically. It depends on the trust's structure and whether the assets are removed from your taxable estate under current federal and state rules, which is why irrevocable trusts for tax purposes should be drafted with a specific goal in mind.
Who controls an irrevocable trust once it is signed?
The trustee named in the document controls and administers the trust according to its written terms. The person who created the trust typically cannot serve as trustee with unrestricted power without undermining the trust's irrevocable status.
Is a revocable trust worth it if it does not protect assets from creditors?
Yes, for most people the value of a revocable trust is probate avoidance, privacy, and incapacity planning, not creditor protection. Asset protection is a separate goal that usually calls for irrevocable planning.
Can a trust be part revocable and part irrevocable?
Some estate plans use a revocable trust during life that splits into irrevocable subtrusts at the settlor's death, often for tax planning or to protect a surviving spouse's inheritance.
How long does it take to set up either type of trust?
A revocable living trust can typically be drafted and signed in a matter of days once you have decided on your trustees and beneficiaries. An irrevocable trust for a specific tax or Medicaid goal usually takes longer, since the terms need to be drafted carefully around a rule that cannot be undone later.
