Property taxation: transfer of base year value: disaster relief.
Summary
Existing property tax law provides, pursuant to a requirement of the California Constitution, that the property tax base year value of real property that is substantially damaged or destroyed by a disaster, as declared by the Governor, may be transferred to a comparable property located within the same county that is acquired or newly constructed, or to replacement property reconstructed on the site of the damaged or destroyed property, within 5 years after the disaster as a replacement property. This bill would authorize the county board of supervisors of any county proclaimed by the Governor to be in a state of emergency, or otherwise determined or declared by the Governor to be in a state of disaster, on or after January 1, 2026, but before January 1, 2031, to extend both of the above-described time periods to transfer by up to 3 years. The bill would apply to the determination of base year values for lien dates occurring on or after January 1, 2026, and before January 1, 2034. 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.

MINOR
The Senate amendment extends the deadline for disaster-related property tax base year value transfers from January 1, 2031 to January 1, 2034, giving property owners an additional three years to benefit from the provision. This applies to both the transfer of base year value to replacement property (Section 69) and the application of base year value to reconstructed property (Section 70). A minor grammatical error was also corrected.
Scope change
The bill's scope was expanded by extending the effective period for disaster relief base year value transfers by three years, from 2031 to 2034.
TIMELINE
The deadline for lien dates eligible for the county board of supervisors' three-year extension of the base year value transfer period was changed from January 1, 2031 to January 1, 2034. This appears in both Section 69(a)(2)(B) (transfer to replacement property) and Section 70(b)(2)(B) (application to reconstructed property).
TECHNICAL
Corrected a grammatical error in the definition of comparable property: 'the property which that it replaces' was changed to 'the property that it replaces.'
