When you transfer a house to a living trust in California, you record a deed that moves title from you to the trust's trustee. For owners of a long-held mid-century home, the first question is whether that deed resets the property tax base. For a trust you can revoke, state law says it doesn't. The paperwork around the deed still matters: the change of ownership report, the transfer tax line and the homeowners' exemption.
This guide covers those pieces using the Revenue and Taxation Code, the Board of Equalization's (BOE) Property Tax Rule 462.160, the current BOE-502-A form, and county assessor and recorder pages for Santa Clara and San Mateo counties, all read on November 6, 2026. It doesn't tell you whether a trust fits your plans. That is a question for an estate planning attorney.
Why the deed into your own revocable trust isn't a reassessment
In California, property is reassessed when it changes ownership or when new construction is completed. The BOE's overview of the property tax calls the value set at that point the base year value. On a long-held Eichler or post-and-beam house, a reset to current value would matter.
Revenue and Taxation Code section 62(d) excludes from change in ownership any transfer by the trustor, or the trustor's spouse or registered domestic partner, into a trust for as long as the transferor is the present beneficiary or the trust is revocable. The same subdivision covers a transfer by the trustee of that trust back to the trustor.
Property Tax Rule 462.160 says the same in more detail, as of November 2026:
The general rule. A transfer of real property into a trust is a change in ownership at the time of the transfer.
Revocable trusts. A transfer by the trustor to a trust the trustor can revoke is not a change in ownership.
Trusts where you are the only present beneficiary. A transfer to an irrevocable trust in which the trustor-transferor is the sole present beneficiary is also excluded, but a change in ownership occurs to the extent anyone else is or becomes a present beneficiary, unless another exclusion applies.
Taking the house back out. Ending a trust is generally a change in ownership, but not when the trustor revokes it and the trustee transfers the property back to the trustor.
The BOE's change in ownership FAQ lists transfers to a revocable trust, where the transferor keeps the power to revoke or the trust is for the benefit of the transferor or the transferor's spouse, among the transfers that are excluded.
What changes when the trust becomes irrevocable
The exclusion lasts only as long as its conditions do. Rule 462.160 says a change in ownership occurs when a revocable trust becomes irrevocable, unless the trustor remains or becomes the sole present beneficiary, or another exclusion applies. In the rule's first example, the trust's terms make it irrevocable at the trustor's death, and the property changes ownership because someone else becomes the present beneficiary.
The rule's examples show that when one spouse dies, the result depends on who the trust names as present beneficiaries and whether an exclusion, such as the interspousal or parent-child exclusion, covers each of them.
Two practical points for trustees, as of November 2026:
A filing deadline. Revenue and Taxation Code section 480 says that after a death, including a transfer through a trust, the trustee or transferee files a change in ownership statement within 150 days after the date of death.
Children who inherit. For parent-child transfers on or after February 16, 2021, the BOE's FAQ says Proposition 19 applies. Our guide to Prop 19 and inherited homes covers its conditions and value cap.
If the trustee sells the house instead, our guide to a probate or trust home sale in California explains the trustee's notices and timing.
The Preliminary Change of Ownership Report (BOE-502-A)
The Preliminary Change of Ownership Report, or PCOR, goes to the recorder with the deed. The current BOE sample is revision 19, dated May 2025, and it is watermarked with a note to contact the assessor for the actual form. Its first page says it is completed by the transferee under section 480.3 of the Revenue and Taxation Code and must be filed with each conveyance in the county recorder's office where the property is located.
Parts of the form that matter for a deed into your own trust:
Part 1, item L. It asks whether this is a transfer to or from a revocable trust that may be revoked by the transferor and is for the benefit of the transferor or the transferor's spouse or registered domestic partner. A second line covers an irrevocable trust for the benefit of the creator, grantor or trustor or that person's spouse or registered domestic partner.
Principal residence. The form asks whether the property is intended as your principal residence and the date of occupancy. Its instructions suggest considering where you are registered to vote, the address on your car registration and where you normally return after work.
The recording fee. The form says that if a document showing a change in ownership is recorded without a PCOR, the recorder may charge an additional $20. The Santa Clara County Clerk-Recorder's page says an additional $20.00 will be due when a required PCOR isn't submitted at recording.
The form says it may be used in all 58 California counties and is not subject to public inspection.
Documentary transfer tax: claiming the exemption on the deed
San Mateo County's recorder gives its county documentary transfer tax rate as 55 cents per $500, or fraction thereof, and the Santa Clara County Clerk-Recorder gives the same $.55 per $500, as of November 2026.
San Mateo County's documentary transfer tax page lists, under section 11930, a deed that transfers the grantor's interest to or from a revocable trust. The deed must include a statement that the trust is for the benefit of the grantor and that the transfer is not pursuant to a sale. For any exempt transfer, the page says to show the tax as "$0" or "none" and to state the exemption and its Revenue and Taxation Code section on the face of the document. The text of section 11930 itself speaks of transfers by gift or by reason of a death, so ask your own recorder which exemption it accepts for a deed into your own trust.
Santa Clara County's recording page says that if no tax is due, enter "0" on the tax line and give a valid reason for the exemption. Its recorder's office also says it is prohibited by law from giving legal advice, including suggesting what forms to use.
Some Bay Area cities charge their own transfer tax with their own rules. Our guide to Bay Area transfer taxes by city lists the city taxes we could confirm. Ask your city whether a deed into your own trust is exempt there, as of November 2026.
The homeowners' exemption after the deed
The BOE describes the homeowners' exemption as a $7,000 reduction in the taxable value of a qualifying owner-occupied home. Our guide to the homeowners' exemption in California covers who qualifies and the filing deadlines. A deed into your own trust can end it in at least one Bay Area county.
The Santa Clara County Assessor's homeowners' exemption page says that recording a deed, including transferring the property into or out of a trust, adding or removing co-owner names, or recording a deed to change names, automatically ends the exemption for the upcoming fiscal year, and that a new claim is sent to the new owner of record.
San Mateo County's assessor page says new property owners automatically receive an exemption application in the mail. It doesn't address trust deeds. We couldn't read Alameda County's assessor pages on this point. Practices differ, so ask your county assessor whether recording your trust deed will end the exemption, and watch your mail for a claim form after recording.
A checklist for recording day and after
Have your attorney prepare the deed and confirm how the trustee and the trust are named on it.
Complete the PCOR, including item L in Part 1 and the principal residence question, and file it with the deed to avoid an extra recording fee ($20 in Santa Clara County).
Check that the transfer tax line shows a zero amount, with the exemption statement and the code section your county asks for.
Watch for a homeowners' exemption claim from the assessor and return it by the deadline on the form.
Check your next tax bill to confirm the exemption is still applied.
This is general information as of November 2026, not legal or tax advice. Trusts, deeds and exclusions depend on the documents and the facts, so work with an estate planning attorney and a tax advisor, and confirm forms and fees with your own county assessor and recorder.
Frequently asked questions
Will putting my house in a living trust raise my property taxes?
Not for a transfer into a trust you can revoke. Revenue and Taxation Code section 62(d) and Property Tax Rule 462.160 exclude it from change in ownership, so the base year value stays the same. A change in ownership can occur later, when the trust becomes irrevocable, unless you remain the sole present beneficiary or another exclusion applies.
Do I pay documentary transfer tax when I deed my house to my trust?
San Mateo County lists a deed transferring the grantor's interest to or from a revocable trust as exempt under section 11930, if the deed states the trust is for the grantor's benefit and the transfer is not a sale. The exemption has to be written on the deed. Check your county recorder and your city.
Do I have to refile the homeowners' exemption after the deed is recorded?
In Santa Clara County, the assessor says recording a deed into a trust ends the exemption for the upcoming fiscal year and that a new claim is sent to the new owner of record, so expect to file it. Other counties may handle it differently, so ask yours.
