The California Constitution generally limits ad valorem taxes on real property to 1% of the full cash value of that property. For purposes of this limitation, “full cash value” is defined as the assessor’s valuation of real property as shown on the 1975–76 tax bill under “full cash value” or, thereafter, the appraised value of that real property when purchased, newly constructed, or a change in ownership has occurred. The California Constitution authorizes the Legislature to provide that a severely disabled person and a person over 55 years of age may transfer the base year value, as defined, of property that is eligible for the homeowners’ property tax exemption to a replacement dwelling that is of equal or lesser value located within the same county as the property from which the base year value is transferred and the replacement dwelling is purchased or newly constructed within 2 years
of the sale of the original property, subject to certain conditions.
This measure would additionally authorize the Legislature to provide, commencing with the 2016–17 fiscal year, for the transfer of base year value to a replacement dwelling that is of greater value, and would require the base year value of the replacement dwelling to be calculated by adding the difference between the full cash value of the original property and the full cash value of the replacement dwelling to the base year value of the original property.
