Propositions 60 and 90 are constitutional amendments passed by California voters that provides property tax relief for persons aged 55 and over.  Implemented by section 69.5 of the Revenue and Taxation Code*, it allows these persons, under certain conditions, to transfer a property's factored base year value from an existing residence to a replacement residence.

Typically the property tax of a newly purchased or constructed residence is based on its current market value upon change of ownership.  However, the provisions of Proposition 60 and 90 may result in substantial tax savings since it allows the adjusted base year value of the original (sold) property to be transferred to the newly purchased or constructed home if eligibility requirements are met.

*Section 69.5 also sets forth the provisions of Proposition 110 - which allows the transfer of a base year value for severely and permanently disabled persons.  Except for the disability factor, the qualifications of Propositions 60/90 are the same as Proposition 110.

What is the difference between Proposition 60 and Proposition 90?

Proposition 60 allows transfers of base year values within the same county (intracounty).  Proposition 90 allows transfers from one county to another county in California (intercounty) and it is the discretion of each county to authorize such transfers.  As of September 19, 2013, only nine counties have passed an ordinance authorizing intercounty transfers: however, it is recommended that you call your assessor for verification as it could change at any time.  The nine counties in California enabling the intercounty base year value transfers are:

Alameda,  El Dorado,  Los Angeles,  Orange,  Riverside,  San Diego,  San Mateo,  Santa Clara,  Ventura
