Property Tax Reassessment After a Death in California

Usually yes. Death transfers ownership, which is a change of ownership that reassesses the property to market value — unless an exclusion applies (for example, the property passes to a spouse, or to a child who makes it their primary residence under Proposition 19). The reassessment is not automatic in every case; it depends on who receives the property.

When you inherit real property in California, the county treats the transfer as a change of ownership and generally reassesses the home to its current market value — resetting the parent's low Proposition 13 base and often raising the tax sharply. Under Proposition 19 (effective February 2021), a parent-to-child transfer only keeps the low base if the child makes the home their own primary residence (and even then the exclusion is capped); an inherited rental or second home is reassessed in full. So whether your property tax stays low on inherited property depends on how you use it, not just on the family relationship.

It's a form (BOE-502-D) that must be filed with the county assessor when a property owner dies, whether or not the estate goes through probate. It reports the death and how the property is passing, so the assessor can determine whether a reassessment or an exclusion applies. It is generally due within 150 days of the date of death; filing late can mean penalties.

Sometimes. Under Proposition 19 (since February 16, 2021) the parent-child exclusion applies if the child makes the home their own primary residence (moving in within one year) and files the exclusion claim within three years of the transfer — or before selling to a third party, if sooner; a claim is also timely if filed within six months after the mailing of a supplemental or escape assessment notice for the transfer. To get the exclusion from the transfer date, the Homeowners' (or Disabled Veterans') Exemption must also be filed within one year; a late filing, while the child still owns the home, gets relief only from January 1 of the year it is filed, so the years in between stay at the reassessed value (BOE Letters to Assessors 2025/009 and 2026/026). File the exemption first and confirm with the county assessor. Only the first $1 million of value above the assessed value is protected — the cap is inflation-adjusted every other February and is $1,044,586 for transfers from February 16, 2025 through February 15, 2027 (BOE Letter to Assessors 2025/009). A home kept as a rental or second home, or value above that cap, is reassessed.

File state form BOE-19-P — "Claim for Reassessment Exclusion for Transfer Between Parent and Child Occurring on or After February 16, 2021" — with the county assessor where the property sits (most assessors post it on their forms page). It is timely if filed within three years of the transfer or before a sale to a third party, whichever is earlier, or within six months after the mailing of a supplemental or escape assessment notice for the transfer, as above. The older form BOE-58-AH covers only transfers before February 16, 2021. For a family home you must also claim the Homeowners' Exemption within one year, as above.

When a revocable living trust becomes irrevocable on the settlor's death, the property passing to the trust's beneficiaries is generally a change of ownership — subject to the same exclusions (spouse, parent-child primary residence) as any other transfer at death. The trust itself does not avoid reassessment; who ultimately receives the property, and how they use it, decides the result.

No. Transfers between spouses — including on the death of one spouse — are fully excluded from reassessment, with no value cap. The surviving spouse keeps the existing Proposition 13 base.

Property passing to a surviving joint tenant can be excluded from reassessment under the joint-tenancy rules (the 'original transferor' rules), but the details decide the outcome. Adding children as joint tenants is not a reliable way to avoid reassessment at death — the parent-child rules still apply.
