Most people facing this question are adult children who have just inherited a parent's house, or who expect to, and are trying to work out what the next property tax bill will look like. They may be weighing whether to move in, keep the house as a rental, or sell it, and siblings are often waiting on the answer. Someone may also have repeated the old rule that a child "always" keeps the parent's tax base. That rule changed in 2021, and the new one depends on who lives in the house and what it is worth.
This page explains the parent-child exclusion under Proposition 19: what it does, who qualifies, the value limit, how a claim is filed, and what falls outside it.
What the Parent-Child Exclusion Means Under California Law
For a family that has just inherited a house, the exclusion decides whether the property tax bill stays close to what the parent paid or jumps. Ordinarily, when real property changes ownership, the county assessor resets its assessed value to current market value. That reset is called reassessment, and in a house a parent owned for decades it can raise the annual tax sharply.
The parent-child exclusion keeps that reset from happening when the conditions are met. For transfers on or after February 16, 2021, the governing law is Rev. & Tax. Code section 63.2, which says a change in ownership "shall not include" a qualifying transfer of a parent's principal residence or family farm "for which a claim is filed." The child keeps the parent's taxable value. The State Board of Equalization's Proposition 19 Fact Sheet defines taxable value as "the base year value plus inflationary adjustments," also called the factored base year value.
The exclusion is not automatic. Rev. & Tax. Code section 63.2 says it "shall not be allowed unless a claim" is filed with the assessor. Where a parent has died, the Fact Sheet says the date of death is treated as the date of transfer, so that date drives most of the rules below. How these rules differ from the older Proposition 58 rules is covered in its own section further down.
Which Transfers Qualify: The Primary Residence Requirement
Rev. & Tax. Code section 63.2 limits the exclusion to two kinds of property: a family home and a family farm. A family home means a dwelling eligible for the homeowners' or disabled veterans' exemption because the parent owned and lived in it. It includes only a reasonably sized piece of land used as the site for the residence. So the house must have been the parent's principal residence at the time of the transfer, which for an inheritance is the date of death.
The child then has to make it their own home. Under the statute, the property must "become the principal residence of the transferee within one year of the transfer," and the child must file for the homeowners' or disabled veterans' exemption within a year of the transfer. The Board of Equalization's Letter To Assessors No. 2026/026 adds that there are "no exceptions" to the requirement that the home become the child's principal residence within one year. For a family still deciding what to do with the house, that year can pass quickly.
If the exemption claim is filed after that year, the Fact Sheet says the exclusion begins in the year the claim is filed rather than on the transfer date. Where two or more children inherit and one moves out while another moves in, the Fact Sheet says a new claim must be filed within one year of the first child's move-out date. The deadline for the exclusion claim itself is covered in the filing section below.
The Value Limit: When Reassessment Still Applies Partially
Even a home that meets every condition can still be partly reassessed, which surprises many families in higher-priced areas. Rev. & Tax. Code section 63.2 sets the new taxable value as the parent's taxable value plus one more piece. If the home's fair market value at transfer is less than the parent's taxable value plus $1,000,000, that extra piece is zero. If the market value is equal to or more than that sum, the difference is added on top.
The $1,000,000 figure is adjusted every other year, so the number that matters for a particular family depends on when the transfer happened. The Board of Equalization's Letter To Assessors No. 2025/009 lists the amounts by date of transfer. The amount is $1,000,000 from February 16, 2021, through February 15, 2023, and $1,022,600 from February 16, 2023, through February 15, 2025. It is $1,044,586 from February 16, 2025, through February 15, 2027. The letter says the next adjustment occurs in February 2027. For an inherited home, the figure in effect on the date the parent died is the one used. The Board of Equalization or the county assessor publishes any later figure.
A hypothetical, for illustration only. Suppose a parent died in March 2025 and their home had a factored base year value of $300,000 and a market value of $1,600,000. The limit is $300,000 plus $1,044,586, or $1,344,586. The market value exceeds that by $255,414, so the child's new taxable value would be $300,000 plus $255,414, or $555,414. That is well below a full reset to $1,600,000.
Proposition 58's residence exclusion in Rev. & Tax. Code section 63.1 carried no comparable cap on the family home. For homes in high-value areas, that is often the change families notice most.
How to File a Claim with the County Assessor
The claim goes to the county assessor in the county where the property sits, not to a state agency. The Proposition 19 Fact Sheet names the form as BOE-19-P, the Claim for Reassessment Exclusion for Transfer Between Parent and Child Occurring On or After February 16, 2021. The Board of Equalization's Proposition 19 page collects its guidance, and the county assessor's office is the place to ask about county procedures and supporting documents.
In the months after a death, a family is often keeping track of more than one date at once, so it helps to take the deadlines one at a time. Under Rev. & Tax. Code section 63.2, the exclusion claim is due within three years after the transfer. If the property is transferred to a third party first, or the eligible child stops living in the home first, the claim is due before that happens. Whichever of those comes earliest controls. A claim is also timely if filed within six months after the assessor mails a notice of supplemental or escape assessment for the transfer. A separate, longer window applies to certain properties damaged in the 2025 wildfires the statute names. If every period has passed and the child still owns the property, the assessor will still consider a late claim. Relief then begins with the lien date of the year the claim is filed.
Sometimes the assessor writes first, saying the child may be eligible. In that case the statute gives 45 days to file a certified claim. A second notice may follow with 60 days. After that, the county may charge a one-time processing fee of no more than the assessor's actual costs or $175, whichever is less.
A separate filing is easy to confuse with the exclusion claim. Rev. & Tax. Code section 480 requires a change in ownership statement after a death. In a probate, the personal representative files it at or before the time the inventory and appraisal is filed. Otherwise, the trustee or the person receiving the property files it within 150 days after the date of death. How this fits into the wider estate is part of settling a parent's estate.
What Prop 19 Does Not Cover: Transfers That Still Trigger Reassessment
The limits of the exclusion matter as much as its reach, especially for a family holding more than one property. The Board of Equalization's Proposition 19 page says plainly that "the transfer of a rental home between parents and children would not qualify." Because Rev. & Tax. Code section 63.2 covers only a family home or a family farm, a vacation home, a rental or commercial property generally changes ownership and is reassessed in the ordinary way.
The occupancy rule also cuts off the exclusion. If no eligible child makes the home a principal residence within one year, the exclusion does not apply. If the home later stops being an eligible child's principal residence, the Board's page says it receives a new taxable value. That value is the fair market value on the date of inheritance, adjusted for inflation, enrolled on the next lien date after the move-out.
A grandparent-to-grandchild exclusion exists under the same statute, but only where all of the grandchild's parents who are children of the grandparents have died as of the transfer. Stepparents are not counted in that test.
Ownership through an entity is another boundary. Rev. & Tax. Code section 63.2 says real property "does not include any interest in a legal entity," which can matter where a house sits in an LLC or corporation.
Trusts are treated differently. The statute's definition of transfer includes a transfer through a trust. Letter To Assessors No. 2026/026 says the assessor looks through the trust to see who has present beneficial ownership. The answer then turns on the trust's terms and how title is held. The county assessor's office reviews exclusion claims. A CPA, an enrolled agent or a tax attorney reviews income-tax and basis questions, which are their own subject, explained in capital gains on inherited property. Where heirs or a trustee disagree about the house, that contested matter is handled by an attorney who litigates trust and probate cases.
Proposition 19 and the Prior Rules: What Changed in February 2021
Many families heard about the old rules from a parent, a neighbor or an older article, which is why this point causes so much confusion. Proposition 58, under Rev. & Tax. Code section 63.1, excluded a parent's principal residence. It also excluded "the first one million dollars ($1,000,000) of full cash value of all other real property" passing between parents and children.
The Board of Equalization's Proposition 19 page says Proposition 58 applies to dates of death on or before February 15, 2021. Proposition 19 applies to dates of death on or after February 16, 2021, under Rev. & Tax. Code section 63.2. One detail is easy to miss: the page notes that, because February 15, 2021, was a state holiday, transfers accomplished by February 16, 2021, could still be eligible for Proposition 58.
Put side by side, the newer exclusion is narrower in three ways covered above: it reaches only a family home or family farm, it requires an eligible child to live in the home, and it applies the value limit. A family whose transfer happened before February 16, 2021, can ask the county assessor which rules apply to that date.
Some readers search for whether Proposition 19 may be repealed. The rules described here are those in Rev. & Tax. Code section 63.2 as currently written. The Board's Proposition 19 page says its FAQs "will be updated" as questions arise. The current status of any proposal is published by the Board of Equalization and on the Legislature's California Legislative Information site. The wider picture is in Proposition 19 and inherited property.
If You Are Working Out What Happens to a Parent's Home
Deciding whether to move into a parent's house, while also tracking an exemption deadline and a claim form, is a lot to carry in the months after a death. Which rules apply turns on the date of death, how title was held, whether there is a trust, and who will live in the home.
The Find Your Next Step questionnaire at Silver Lining Estate asks about the reader's role, whether there is a will or a trust, whether real estate is involved, and what the reader is trying to work out, and then points to the guides and the kinds of professionals that fit.
