Prop 19 and the Inherited House: How Reassessment Works

An inherited California house keeps the parent’s low property tax only if a child moves in within one year and files for the homeowners’ exemption, and even then only up to a cap. Everything above the cap is reassessed, and a rental, a second home, or a house no child moves into is reassessed to full market value as of the date of death. For deaths from February 16, 2025 through February 15, 2027, the protected amount is the parent’s factored base-year value plus $1,044,586 (Rev. & Tax. Code § 63.2 and BOE Letter To Assessors 2025/009).

Prop 19 is a property tax rule, and what’s at stake is the property tax bill every year after. California has neither an inheritance tax nor an estate tax (Rev. & Tax. Code § 13301).

If you’re still deciding whether to keep the house at all, start with what to do with an inherited house in California, which compares selling, moving in, renting, a 1031 exchange, and a sibling buyout.

A child who moves in keeps the parent’s tax value, up to a cap

If a child moves in, the exclusion can lower the yearly bill. On a $1.2 million house with a $250,000 base, it holds the bill to about $2,750 a year, against about $13,200 if the house is fully reassessed.

Whether the cap bites depends on how far the house has outgrown the parent’s value. Under R&TC § 63.2(d), you add the exclusion amount to the parent’s factored base-year value (the Prop 13 value, grown by up to 2% a year). If the market value at death is below that total, the child keeps the parent’s value. If it’s above, the excess is added to the parent’s value.

Check the date of death before you run numbers, because it picks the exclusion amount. The date the trust distributes or the probate closes doesn’t matter. The amount is adjusted every other February 16 using a California house price index. It was $1,000,000 for transfers from February 16, 2021 through February 15, 2023, $1,022,600 for transfers from February 16, 2023 through February 15, 2025, and is $1,044,586 now. The tax figures above assume about 1.1%, and actual rates vary by tax rate area, usually between 1% and 1.25% of assessed value. To run your own numbers, use the Prop 19 reassessment calculator.

The house qualifies only when a child moves in and files within a year

A house keeps the parent’s tax value only when all of these are true:

• It was the parent’s principal residence, eligible for the homeowners’ or disabled veterans’ exemption.
• It passes to a child (or to a grandchild whose parent, the grandparent’s child, has died).
• The child makes it the child’s own principal residence and files for the homeowners’ exemption, Form BOE-266, within one year of the death.
• Someone files the exclusion claim, Form BOE-19-P (BOE-19-G for a grandchild).

If no child moves in and files, the house is reassessed to market value. The conditions come from Prop 19, which replaced the old parent-child exclusion for transfers on or after February 16, 2021. Its authority is Cal. Const. art. XIII A, § 2.1 and R&TC § 63.2. The regulation that implements it is Property Tax Rule 462.520, and the BOE’s most recent guidance is Letter To Assessors 2026/026, issued August 3, 2026, a question-and-answer set on intergenerational transfers.

Don’t rely on the old Proposition 58 exclusion for a recent death. It protected any parent-child transfer of a residence with no move-in requirement, and it still applies only to deaths on or before February 15, 2021 (former R&TC § 63.1).

A revocable living trust doesn’t change who gets reassessed

A trust won’t keep an inherited house from being reassessed under Prop 19. If you’re counting on a trust to avoid reassessment, don’t: the BOE looks through the trust to the parent and the child (Rev. & Tax. Code § 63.2 and LTA 2026/026), so the result is the same whether the house comes through a trust, a will, or a transfer-on-death deed. A 2026 law, SB 974, names a court-established special needs trust as an eligible medium of transfer under the parent-child exclusion starting January 1, 2027. The same look-through and move-in rules apply.

The move-in and claim deadlines run from the date of death

Missing the move-in window or filing the homeowners’ exemption late can cost you the exclusion, and a late claim gets partial relief. The date of death starts the clock on both periods.

• Trustee delay doesn’t extend anything. The three-year claim period and the one-year move-in window both run from the date of death. The assessor can accept a claim before the trust is distributed (LTA 2026/026).
• A late claim gets partial relief. A claim filed within six months after the assessor mails a supplemental or escape assessment notice is still timely. After that, relief runs only from the January 1 lien date of the year you file, and only if the house hasn’t been sold.
• A late homeowners’ exemption can cost you the exclusion. If the child moved in on time but didn’t file BOE-266 within the year, and has since sold, the BOE says the exclusion can’t be applied at all (LTA 2026/026).
• Penalty for not filing BOE-502-D. If the assessor asks in writing and nobody files within 90 days, the penalty is $100 or 10% of the new tax, whichever is greater, capped at $5,000 for a house eligible for the homeowners’ exemption unless the failure was willful (Rev. & Tax. Code § 482).

Expect a supplemental tax bill after any reassessment. It covers the rest of the fiscal year at the new value and arrives separately from the regular bill (Rev. & Tax. Code § 75 et seq.). Filing mechanics are covered step by step in how to file the Prop 19 exclusion.

Where to file in Ventura County

For a Ventura County house, the claim goes to the Ventura County Assessor’s Office, in the Hall of Administration at the Ventura County Government Center, 800 S. Victoria Avenue, Ventura, CA 93009, phone (805) 654-2181. The exclusion claim is filed with the county assessor (R&TC § 63.2(b)), and the office’s forms page carries the homeowners’ exemption claim, BOE-266.

The low property tax and the clean sale can’t both be had

Keeping the low property tax requires a child to live there, and capturing the clean sale requires selling. No trust or deed arrangement gets you both. The income tax rule works in the other direction: an inherited house takes a new basis equal to its value on the date of death (IRC § 1014), so a prompt sale usually produces little or no capital gains tax. Say your mother bought her Ventura County home in 1985 for $120,000 and it’s worth $850,000 when she dies. Sell a few months later for $860,000 and the taxable gain is about $10,000 before selling costs, not $740,000. For the income tax side in full, see capital gains tax on inherited property.

With siblings, one child living there is enough, and the way the trust divides assets matters

Only the parent-to-child transfer is excluded.

Only one child has to live there. Title can go to all the children, and the exclusion applies as long as one of them makes it a principal residence and files the homeowners’ exemption (LTA 2026/026).

Unequal distributions from a trust can protect the whole house. California lets a trustee distribute different assets to different beneficiaries (Prob. Code § 16246). The BOE treats the whole house as coming from the parent when the child who takes it receives less of everything else, as long as the house’s value doesn’t exceed that child’s share of the entire trust. Anything above that share is treated as coming from the siblings and is reassessed. If the trust names a specific child for the house, the trustee can’t rearrange it.

Buying out siblings after distribution is a sibling transfer. If the house is deeded to three children equally and one later buys the other two out, the two-thirds bought from siblings is reassessed. In one BOE example, two brothers swapped their half interests in two inherited houses after distribution, and each house was 50% reassessed (LTA 2026/026).

A trust loan can fund the siblings’ shares. Some county assessors accept a structure where the trust borrows against the house to pay the other beneficiaries before the house is distributed, as long as the child keeping the house isn’t the lender. The BOE hasn’t addressed this in a Letter To Assessors, so confirm with your county assessor before relying on it. Details in buying out a sibling without losing the Prop 19 basis.

The exclusion ends when the child stops living there

If the child moves out, the low tax value goes away, though another eligible child who moves in within a year can restore it. The exclusion lasts only while an eligible child lives there. When the child stops qualifying for the homeowners’ exemption, the assessor enrolls the date-of-death market value, grown for inflation, as of the next January 1 lien date (R&TC § 63.2(a)(1) and Property Tax Rule 462.520).

Don’t deed the house into the child’s own LLC or rent it out, because either one ends the exclusion. Deeding it to an LLC, even a single-member LLC, is a transfer to a third party, and renting the house out means it’s no longer the child’s principal residence.

A rental, cabin or commercial building gets no exclusion

Property that wasn’t the parent’s home is reassessed to market value as of the date of death (LTA 2026/026). For a long-held rental, that’s often the largest cost of inheriting it, and a reason to think hard before the family keeps it. See Prop 19 planning for what parents can still do during life.

A family farm is the exception. It qualifies without anyone living there, and the cap applies separately to each legal parcel (Rev. & Tax. Code § 63.2(a)(2)).

A mortgage or reverse mortgage doesn’t change the Prop 19 analysis

Neither kind of home loan changes the Prop 19 analysis, so whichever one is on the house, the reassessment math stays the same. They differ in what happens at death, though. A regular mortgage survives the death, and the lender can’t call the loan only because the house passed to a relative (12 U.S.C. § 1701j-3(d)). A reverse mortgage comes due at death, and heirs who want to keep the house pay the lesser of the balance or 95% of appraised value. See inheriting a house with a reverse mortgage.

Frequently asked questions

How much will my property tax be if I move into my parents’ house under Prop 19?

For deaths from February 16, 2025 through February 15, 2027, the new taxable value is the parent’s factored base-year value plus any market value above that base plus $1,044,586 (Rev. & Tax. Code § 63.2). A $1.4 million house with a $300,000 base is reassessed to $355,414, roughly $3,900 a year at a 1.1% rate.

Do all the heirs have to live in the house to keep the Prop 19 exclusion?

No. Only one eligible child has to make the inherited house a principal residence and file the homeowners’ exemption within one year of the death. Title can be held by all the children (BOE Letter To Assessors 2026/026). The exclusion ends when no eligible child lives there anymore.

Does a living trust protect me from Prop 19 reassessment?

No. A revocable living trust does not shield an inherited house from Prop 19 reassessment. The assessor looks through the trust to the parent and child (Rev. & Tax. Code § 63.2), so the house is treated the same as if it passed by will. A trust avoids probate; it is not a Prop 19 workaround.

When is the Prop 19 claim form due?

Form BOE-19-P is due within three years of the parent’s death and before the house is transferred to anyone else or the child stops living there (Rev. & Tax. Code § 63.2(f)(1)(A)). Separately, the child must move in and file the homeowners’ exemption within one year, and the change in ownership statement, BOE-502-D, is due 150 days after death, or in probate when the inventory and appraisal is filed.

What happens to the Prop 19 exclusion if I move out of the inherited house?

The exclusion ends when no eligible child lives in the house as a principal residence. The assessor then enrolls the date-of-death market value, adjusted for inflation, as of the next January 1 lien date. If another eligible child moves in within a year, the exclusion can be restored.

Is Proposition 58 still the law for parent-child transfers?

Only for deaths on or before February 15, 2021. Prop 19 replaced the old Prop 58 exclusion (former Rev. & Tax. Code § 63.1) for later transfers (Cal. Const. art. XIII A, § 2.1; Rev. & Tax. Code § 63.2). Under Prop 19 the child must live in the home, and the protected value is capped.

Does a rental property I inherit get reassessed in California?

Yes. An inherited rental or second home is reassessed to market value as of the date of death, because Prop 19 excludes only the parent’s principal residence and family farms (Rev. & Tax. Code § 63.2). The heir’s plans for the rental don’t change that result.
