Families often hear “get a trust” and then learn there are two main kinds. The choice between revocable and irrevocable shapes who controls your assets, how your family avoids court and how taxes work. This page explains both in plain terms, with a California focus.
It is general education, not legal or tax advice. A California estate attorney should draft and review any trust.
What is the difference between a revocable and an irrevocable trust?
A revocable trust can be changed or canceled while you live. An irrevocable trust generally cannot. That one difference drives most of the others: control, taxes, creditor protection and cost.
Here is the side-by-side view.
| Revocable trust | Irrevocable trust | |
|---|---|---|
| Can you change or cancel it? | Yes | Generally no |
| Who usually controls assets? | You, as trustee, while you live | A trustee under the trust terms |
| Avoids probate? | Yes, for assets properly placed in it | Yes, for assets properly placed in it |
| Income tax treatment | Always a grantor trust, so income is taxed to you | Depends on the powers in the trust |
| Gift tax return? | Generally not for funding | Often due when you fund it |
| Common goals | Probate avoidance, incapacity planning, a clear plan for heirs | Asset protection, estate tax planning, special family situations |
| Flexibility | High | Low |
| Best question to ask | “What do I want to change later?” | “What am I willing to give up for good?” |
The IRS notes that “State law and the trust instrument establish whether a trust is revocable or irrevocable.” Your attorney confirms the details for your trust.
What is a revocable living trust?
A revocable living trust holds your assets while you live and passes them to your heirs when you die. You can change it or end it at any time. The glossary entry on a revocable living trust gives a short definition.
Most people name themselves as trustee, so they manage the assets as before. They also name a successor trustee who steps in if they become unable to manage or when they die.
The trust works only on assets it holds. That means you retitle accounts and property into it, often called funding. A signed trust with nothing in it does little. Many plans also include a pour-over will to catch assets left outside the trust.
What is an irrevocable trust?
An irrevocable trust is a trust that, in the IRS’s words, “by its terms, cannot be modified, amended, or revoked.” When you fund it, you generally give up the right to take the assets back or change the terms. Read more in the irrevocable trust entry.
People use irrevocable trusts for goals such as:
- Protecting assets from certain claims
- Planning for a larger estate
- Providing for a family member with special needs
- Holding life insurance outside the estate
- Setting terms for how and when heirs receive assets
Each goal needs its own design and careful drafting. A trust that is wrong for your situation can cost you flexibility that you cannot get back.
Which one helps my family avoid probate in California?
Both can, if you fund them properly. The California Courts self-help site explains that a living trust “helps loved ones bypass this long waiting period as well as the expense of probate court.” For most families, a revocable trust is the usual tool for this purpose.
Probate in California moves slowly. The state’s self-help guide says the fastest a home can pass through probate is typically 9 months: “The fastest that can happen in California is typically 9 months, and that length of time can create problems for your loved ones.” The glossary entry on probate explains the process.
Our guide to California estate planning lists the documents most families need, and our blog post on why California families still need a trust goes deeper.
How are the two trusts taxed?
A revocable trust is taxed as if you own the assets. An irrevocable trust depends on its terms. Funding an irrevocable trust can also trigger a gift tax return. Ask your CPA how each applies to you.
The IRS makes these points:
- “A revocable trust may be revoked and is considered a grantor trust (IRC § 676).” In a grantor trust, the grantor is treated as the owner, and income is taxed to the grantor.
- An irrevocable trust “can be treated as a simple, complex, or grantor trust, depending on the powers listed in the trust instrument.”
- On gifts: “In situations where an Inter Vivos irrevocable trust is the recipient of property contributed, a gift tax return would generally be due.”
This does not mean tax is owed. A gift tax return reports the transfer. Whether tax is due depends on the amounts and the federal exemption. Check the current amount in the federal estate tax exemption entry and with your CPA, since the figure changes.
Does California have an estate tax?
No. The California State Controller says “a California Estate Tax Return is not required to be filed for decedents whose date of death is after December 31, 2004.” A federal estate tax may still apply to larger estates.
That fact surprises many people. It also leads them to think a trust is not needed. The problem is probate, not the estate tax. A trust can still save your family court time and expense. The step-up in basis rules and Proposition 19 also affect how a trust and a home work together; see our guide on Prop 19 and passing on a California home.
How do I choose between them?
Start with your goals, then match the tool. Most families begin with a revocable trust. Some add one or more irrevocable trusts for specific goals. A California estate attorney sets the design.
Work through these steps:
- Write your goals. Do you want to avoid probate, plan for incapacity, protect a family member, reduce a future estate or give to ministry?
- List your assets. Include your home, accounts, business interests, insurance and retirement plans.
- Decide what you can give up. An irrevocable trust asks you to give up control. Be honest about what you can live with.
- Match each goal to a tool. Probate avoidance points to a revocable trust. Asset protection or estate tax goals may point to an irrevocable one.
- Coordinate the team. Your attorney drafts, your CPA reviews the tax side and your financial advisor lines up the accounts.
- Review on a schedule. Update the trust after births, deaths, moves, sales and law changes.
How does a trust fit with my faith and legacy?
A trust lets you say, in a legal document, who receives what and under what conditions. For many Christian families that also means providing for family and for giving. Proverbs 13:22 speaks of leaving an inheritance for the next generation. You can plan that with care.

Frequently asked questions
What is the main difference between a revocable and an irrevocable trust?
Control. You can change, amend or end a revocable trust during your life. An irrevocable trust, by its terms, cannot be modified, amended or revoked. That tradeoff is why the two serve different goals. The revocable trust favors flexibility and probate avoidance. The irrevocable trust favors protection and tax planning.
Does a revocable trust avoid probate in California?
It can, if your assets are properly placed in the trust. The California Courts self-help site says a living trust helps loved ones bypass the long wait and expense of probate court. A trust that is signed but never funded does little, so retitle your assets with your attorney.
Does a revocable trust save estate taxes?
Not by itself. The IRS treats a revocable trust as a grantor trust, so you are treated as the owner of the assets for tax purposes. Its main job is managing your property and avoiding probate. Estate tax planning usually involves other tools, which your attorney can explain.
Does California have an estate tax?
California does not require an estate tax return for people who die after December 31, 2004, according to the California State Controller. A federal estate tax may still apply to larger estates. A California family can still want a trust to avoid probate and manage assets.
Can I change an irrevocable trust later?
Generally no. The IRS describes an irrevocable trust as one that, by its terms, cannot be modified, amended or revoked. Limited changes may be possible in some cases, so ask a California estate attorney before you sign. Think of it as a permanent decision.
