SB 288 California Senate · 2025-2026 Regular Session

Property taxation: change in ownership: family homes and farms.

Summary
The California Constitution limits the amount of ad valorem taxes on real property to 1% of the full cash value of that property, defined as the county assessor's valuation of real property as shown on the 1975–76 tax bill and, thereafter, the appraised value of the real property when purchased, newly constructed, or a change in ownership occurs after the 1975 assessment, subject to an annual inflation adjustment not to exceed 2%. Pursuant to constitutional authorization, existing property tax law, on and after February 16, 2021, excludes from classification as a change in ownership the purchase or transfer of a family home or family farm, as those terms are defined, of the transferor in the case of a transfer between parents and their children, or between grandparents and their grandchildren if all the parents of those grandchildren are deceased, if the property continues as the family home or family farm of the transferee, as specified. For purposes of the transfer of a family home, that law requires the transfer to be of a principal residence of the transferor and to become the principal residence of the transferee within one year of the transfer. That law also requires the transferee to file for the homeowners' or disabled veterans' exemption within a year of the transfer, as described. This bill would provide that the one-year periods described above shall be deemed to end one year after the effective date of certain court orders resolving the disposition of the property if the eligible transferee files specified documents with the assessor, including a copy of a court order indicating that a probate matter prohibited the eligible transferee from establishing the property as their principal place of residence within the one-year period described above. By expanding the duties of local tax officials, the bill would impose a state-mandated local program. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that, if the Commission on State Mandates determines that the bill contains costs mandated by the state, reimbursement for those costs shall be made pursuant to the statutory provisions noted above. Existing law requires the state to reimburse local agencies annually for certain property tax revenues lost as a result of any exemption or classification of property for purposes of ad valorem property taxation. This bill would provide that, notwithstanding those provisions, no appropriation is made and the state shall not reimburse local agencies for property tax revenues lost by them pursuant to the bill. This bill would take effect immediately as a tax levy.

What changed between versions

01/22/26 - Amended Senate 06/01/26 - Amended Assembly · 3 edits · Jun 1, 2026
MINOR
The Assembly amended SB 288 to change how the one-year deadline for establishing a family home is extended in probate cases, and reversed the Senate's determination on state-mandated local program status. The probate extension now requires the transferee to file specific documentation showing that the probate matter actually prevented them from moving into the property, rather than automatically restarting the clock when any probate order is entered. The Assembly also concluded the bill does impose a state-mandated local program, entitling local agencies to reimbursement for administrative costs.
REQUIREMENT

The probate-related extension of the one-year residence and exemption filing deadline was restructured. Previously, the one-year period would restart (commence) when a probate court order was entered. Now, the one-year period ends one year after the effective date of a court order resolving disposition of the property, but only if the transferee files three specific items with the assessor: an eligibility form, a copy of a court order indicating that the probate matter prohibited the transferee from establishing the property as their principal residence within the original one-year period, and a statement under Section 480(b) of the Revenue and Taxation Code. This narrows the extension to cases where probate actually prevented the transferee from moving in, rather than applying to any probate proceeding.

FISCAL

The Assembly reversed the Senate's fiscal determination on state-mandated local program status. The Senate version designated the bill as NOT a state-mandated local program; the Assembly version designates it AS a state-mandated local program. This means local agencies would be entitled to state reimbursement for the administrative costs of implementing the new assessor duties, though the bill still provides that no appropriation is made for lost property tax revenues.

TECHNICAL

Section numbering was cleaned up. The Senate version had inconsistent section numbers (SEC. 2 appeared twice with out-of-order SEC. 3 and SEC. 4). The Assembly version uses sequential numbering: SEC. 1 (main amendment), SEC. 2 (state mandates reimbursement), SEC. 3 (no appropriation for lost property tax revenue), SEC. 4 (tax levy effective date).
