A revocable trust is a trust you can change or cancel whenever you want. An irrevocable trust is a trust that, once it is signed and funded, generally cannot be changed or undone by you alone. That one difference drives almost everything else: who controls the property, how it is taxed, whether creditors can reach it, and how it affects Medi-Cal.
Most California families only need a revocable living trust. An irrevocable trust is a specialized tool, and it can be the right tool in the right situation. But it can also be an expensive mistake if you give up control for a benefit you did not need.
This guide explains how the two trusts differ under California law, what each does for taxes, property tax (Prop 13 and Prop 19), creditors, and Medi-Cal, which irrevocable trusts are common, and how to decide. It is general information, not legal advice. Your facts matter.
Key Takeaways
- A revocable trust keeps you in control. You can change it, move property in and out, or cancel it. In California a trust is revocable unless it is expressly made irrevocable (Probate Code §15400).
- An irrevocable trust trades control for a specific benefit. That benefit might be Medi-Cal planning, life insurance outside your estate, or protection for a beneficiary.
- A revocable trust avoids probate, but it does not shield assets from creditors, taxes, or Medi-Cal. Its main job is to keep your estate out of court.
- Every revocable trust becomes irrevocable at death. Your successor trustee then has legal duties to follow.
- Medi-Cal rules changed in 2026. The asset limit is back and transfers now have a 30-month look-back, so timing matters more than it used to.

The Short Version
- Revocable trust: You control it, you can change it, it avoids probate, and it is usually the right fit for a home, savings, and a family that wants a simple plan.
- Irrevocable trust: You give up control, and in return it may help with Medi-Cal eligibility, estate taxes, or long-term protection. Use it only for a clear reason.
- Neither one is “better.” They solve different problems. Many people have a revocable trust now and have parts of it become irrevocable later.
What Is a Revocable Trust?
A revocable trust, also called a revocable living trust, is a legal arrangement you create during your lifetime. You transfer your property into the trust, you name a trustee to manage it, and you name beneficiaries to receive it. In most cases you are the trustee while you are alive and well, so you manage everything just as before.
California starts from a simple rule. Under Probate Code section 15400, “unless a trust is expressly made irrevocable by the trust instrument, the trust is revocable by the settlor.” The settlor is the person who creates the trust.
What a revocable trust does well:
- Avoids probate. Property titled in the trust passes to your beneficiaries without court supervision. See how to avoid probate in California and what probate costs.
- Plans for incapacity. If you cannot manage your affairs, your successor trustee can step in without a conservatorship.
- Keeps your plan private. A will becomes a public court record. A trust generally does not.
- Stays flexible. You can update it after a marriage, divorce, new child, move, or change in your finances.
What it does not do: a revocable trust does not reduce your income taxes while you are alive, does not protect assets from your creditors, and does not shelter assets from Medi-Cal. If you want to compare it with a will, see trust vs. will in California.
A revocable trust only works if it is funded. A trust you signed but never put property into leaves your family back in court. Read how to fund a living trust in California.
What Is an Irrevocable Trust?
An irrevocable trust is a trust that cannot be revoked or changed by the person who created it. When you move property into one, you generally give up ownership and control. A trustee holds the property for the beneficiaries under rules you wrote at the start.
That sounds like a loss, and often it is one. People accept it because giving up ownership can create a legal result a revocable trust cannot, such as:
- Moving an asset outside your taxable estate, such as a life insurance policy.
- Setting property aside for a family member who has a disability or cannot manage money.
- Planning for long-term care costs, by transferring assets in a way Medi-Cal may treat differently.
- Making a charitable gift while keeping an income stream.
The exact result depends on how the trust is written. A badly written irrevocable trust can leave you with the downsides and none of the benefits.
Revocable vs. Irrevocable Trust: Side-by-Side Comparison
| Revocable Trust | Irrevocable Trust | |
| Can you change or cancel it? | Yes | Generally no |
| Who controls the property? | You, usually as trustee | The trustee you name, not you |
| Avoids probate? | Yes, if properly funded | Yes, for property in the trust |
| Protects assets from your creditors? | No | Often yes, if properly structured and done early |
| Counts toward Medi-Cal asset limit? | Generally yes | Depends on the trust and timing |
| Reduces estate tax? | No | Can, if assets leave your estate |
| Step-up in basis at death? | Generally yes | Depends on whether assets are in your estate |
| Income taxed to | You, while alive | Depends on how it is written |
| Typical cost to create | Lower | Higher, because it is more complex |
| Best for | Most families who want to avoid probate | Medi-Cal planning, large estates, a family member with a disability, insurance, charity |
Can You Change or Revoke a Trust in California?
Revocable trusts. Yes. California’s Probate Code section 15401 lists the ways to revoke one: by following the method in the trust itself, or by signing a writing (other than a will) and delivering it to the trustee while you are alive. If the trust says its method of revocation is the only method, you must follow that method exactly. Amendments should follow the trust’s own rules as well. Informal changes, like a note in the margin, can cause disputes.
Irrevocable trusts. Generally not on your own, but not never. Under Probate Code section 15403, if all beneficiaries consent, they can petition the court to modify or terminate an irrevocable trust. If keeping the trust in place is needed to carry out a “material purpose” of the trust, the court can allow a change only if the reasons for it outweigh that purpose. In practice that is a court process, with cost and no guaranteed outcome.
The lesson is simple: do not sign an irrevocable trust expecting to undo it later.
When a Revocable Trust Becomes Irrevocable
Every revocable trust has a built-in turning point. When the settlor dies, the trust generally becomes irrevocable. No one can amend it, and the successor trustee must carry out its terms. This is where families first feel the difference between a trust that was planned well and one that was not.
At that point the successor trustee usually has to:
- Secure and inventory trust property.
- Notify the beneficiaries and heirs as California law requires. Probate Code section 16061.7 sets a deadline for this notice, so do not wait.
- Obtain a tax ID number for the now-irrevocable trust and handle its tax filings.
- Pay debts and taxes, then distribute property under the trust.
Couples often have a revocable trust that splits at the first death into a survivor’s trust (still changeable) and a bypass or decedent’s trust (irrevocable). Whether that split makes sense depends on the size of the estate and the family.
Taxes: Revocable vs. Irrevocable Trust in California
Income tax. While you are alive, a revocable trust is generally a “grantor trust.” Its income is reported on your own tax return, so you pay no separate trust tax. An irrevocable trust can be taxed differently depending on how it is written. When a trust keeps its own income, the brackets are compressed. For 2026, one summary of Revenue Procedure 2025-32 reports that the top 37% federal rate applies to trust income above only $16,000. Talk to a CPA about this before you fund an irrevocable trust.
Estate tax. California has no state estate or inheritance tax. For federal purposes, the 2026 estate and gift tax exclusion is $15 million per individual, according to the Bowditch & Dewey summary of the IRS inflation adjustments. The annual gift exclusion is $19,000 per recipient. For most California families, federal estate tax is not the issue. Income tax basis and property tax usually matter more.
Step-up in basis. This is the most overlooked difference. When you die, assets that are in your taxable estate generally get a new “stepped-up” income tax basis equal to their value at death, which can eliminate capital gain on appreciation. In Revenue Ruling 2023-2, the IRS took the position that certain irrevocable trust assets that are not included in the grantor’s estate do not receive that step-up. As The Tax Adviser explains, in its example a $3 million basis asset worth $7 million at death would produce about $4.2 million of taxable gain if sold for $7.2 million, instead of about $200,000 with a step-up.
In other words, moving a highly appreciated home or investment into the wrong kind of irrevocable trust can create a large tax bill for your children. That cost can outweigh the benefit.
Property Tax: Prop 13 and Prop 19
For California homeowners, property tax is often the deciding issue. Under the Board of Equalization’s Rule 462.160, a transfer of real property into a trust is generally a change in ownership, with exclusions:
- Revocable trusts. Transferring property to a revocable trust is not a change in ownership at the time of transfer. The rule says a change in ownership occurs “at the time the revocable trust becomes irrevocable,” unless an exclusion applies, such as the trustor remaining the sole present beneficiary.
- Irrevocable trusts. A transfer can be excluded in several cases, including where the trustor is the sole present beneficiary, where the interspousal exclusion applies, or where the parent-child exclusion applies and a timely claim is filed. If other people become present beneficiaries, a change in ownership can occur “to the extent” they do.
Since Prop 19, parent-child reassessment exclusions are narrower. Read Prop 19 and inherited property in California to see how it affects your children’s property tax. If your plan involves putting a home into an irrevocable trust, check the property tax effect before you sign, not after.
Creditors and Asset Protection
A revocable trust gives you no protection from your own creditors. Because you can take the property back, California law treats it as yours. An irrevocable trust can offer protection, but only when it is structured correctly, you do not keep control of the property, and the transfer is not an attempt to dodge a debt you already owe. Transfers made to avoid existing creditors can be undone by a court.
An irrevocable trust can also protect a beneficiary from their own creditors, divorce, or poor spending habits, when it is written that way. This is the reason many families use trust provisions for adult children.
Do not assume an irrevocable trust is a magic shield. If asset protection is your goal, a California attorney needs to look at your debts, your timeline, and your assets.
Medi-Cal and Long-Term Care Planning
This is the reason many families ask about irrevocable trusts. The rules changed in 2026, so be careful with older articles.
According to the California Department of Health Care Services (DHCS):
- Asset counting began January 1, 2026. Through June 30, 2027, the limit is $130,000 for one person, plus $65,000 for each additional person in the home.
- The limit drops on July 1, 2027, to $21,000 for one person and $31,000 for two, per DHCS.
- Exempt assets include your main home and main vehicle, if you own your home and plan to return to it.
- The look-back is 30 months. Transfers made on or after January 1, 2026 may cause a penalty that delays coverage. Transfers made before January 1, 2026 are not counted.
Here is how that connects to trusts:
- A revocable trust does not protect assets from Medi-Cal. Because you can take the property back, it is generally treated as yours and counted.
- An irrevocable trust may help, but it is not instant. A transfer into one can itself be a transfer that triggers the 30-month look-back, so planning has to happen early.
- You give something up. If the trust is written so you cannot use the principal, you cannot use the principal.
- The home has other risks. Even an exempt home can face recovery after death. Read Medi-Cal estate recovery in California and our guide to Medi-Cal asset limits.
Medi-Cal planning is one of the most time-sensitive areas of estate law. The trust is only one part. The timing, your spouse’s protections, and the type of care all matter.

Common Types of Irrevocable Trusts
These are the irrevocable trusts that come up most often. Each is a specialized tool.
- Irrevocable life insurance trust (ILIT). Owns a life insurance policy so the proceeds can pass outside your taxable estate. It matters most for larger estates.
- Supplemental needs trust. Holds money for a person with a disability without disqualifying them from need-based benefits. See our disability planning resources.
- Medi-Cal or income-only trust. Written so that you may receive income but not principal, as part of a long-term care plan. It must be drafted and timed carefully.
- Charitable remainder trust. Pays you or others an income for a period, then leaves the rest to charity.
- Irrevocable sub-trusts created at death. Often built into a revocable trust to manage property for children, a spouse, or a beneficiary who needs protection.
Which Trust Is Right for You?
| If your main goal is… | Usually points to |
| Avoiding probate on a home and savings | Revocable living trust |
| Planning for incapacity without a conservatorship | Revocable living trust |
| Keeping your plan private | Revocable living trust |
| Protecting a loved one with a disability | Supplemental needs trust (irrevocable) |
| Planning ahead for nursing home costs and Medi-Cal | Irrevocable trust, if timing and facts support it |
| Removing a large life insurance policy from your estate | ILIT (irrevocable) |
| Controlling how children inherit | Revocable trust with sub-trusts |
| Charitable giving with income | Charitable trust (irrevocable) |
If you are in the first group, you probably do not need an irrevocable trust. If you are in the second group, a general plan is not enough, and you should have an attorney review your facts.
Common Mistakes to Avoid
- Making a trust irrevocable too soon. You lose control and may not get the benefit you wanted.
- Waiting too long for Medi-Cal planning. The 30-month look-back rewards early planning.
- Not funding the trust. A trust that never received your property does not avoid probate.
- Ignoring the tax basis. A transfer that loses the step-up can cost your children real money.
- Forgetting property tax. A transfer can change how a property is assessed.
- Using a generic form. Online forms do not know your family or California’s rules.
- Never updating the plan. Laws, assets, and families change.

| Can I turn a revocable trust into an irrevocable trust? | Yes. You can sign an amendment or create a new irrevocable trust and transfer property to it, but doing so can have tax, Medi-Cal, and property tax effects, so get advice first. |
| Can an irrevocable trust be changed in California? | Sometimes. If all beneficiaries consent, they may petition the court under Probate Code §15403. If a material purpose of the trust remains, the court can allow a change only if the reasons outweigh that purpose. |
| Does a revocable trust avoid probate? | Yes, for property properly titled in the trust. Property left out of the trust may still go through probate. |
| Does a revocable trust protect assets from creditors? | No. Because you can take the property back, creditors can generally reach it. |

| Does an irrevocable trust avoid the Medi-Cal look-back? | No. Transfers on or after January 1, 2026 may be reviewed under a 30-month look-back, so early planning matters. |
| What is the Medi-Cal asset limit in 2026? | Per DHCS, $130,000 for one person through June 30, 2027, plus $65,000 for each additional person in the home. It is scheduled to drop on July 1, 2027. |

| Which is cheaper, a revocable or an irrevocable trust? | A revocable trust usually costs less to set up. An irrevocable trust is more complex and more expensive, and it has ongoing tax filings. |
| Do I need an attorney to set up a trust? | You are not required to have one, but a mistake in an irrevocable trust is hard to fix. An attorney can match the trust to your goals and California law. |
