Ordinarily, when the ownership of California real property changes, the property is reassessed at its current fair market value and the new owner pays property tax based on the reassessment which is usually just what it sold for times 1.25%. Proposition 60 created an exemption by providing that the taxpayer who is 55 years of age or older may transfer the Proposition 13 base year assessment of his/her principal residence to any replacement dwelling of equal or lesser value* within the same county. If eligible, the homeowner will pay property tax on the replacement home based on the same assessment value of the former home. Proposition 90 enables such taxpayers, in certain circumstances, to transfer their base year value to a replacement dwelling in another county.
Only certain counties have adopted Proposition 90. They currently are: Alameda, Kern, Los Angeles, Modoc, Orange, San Diego, Santa Clara, San Mateo, and Ventura. It is IMPERATIVE that you verify with the individual county that they are still accepting Prop. 90 transfers. (Caution this can change at any time)
The County Assessor will require a copy of the tax bill from the other county and a copy of the applicant´s birth certificate to be included with the application. Also include a copy of the grant deed from the new purchase and a copy of the closing statements for both the sale and the purchase. In most instances, if more than one owner of an original property is eligible for Proposition 60/90, they must choose among themselves which one will use the benefits.nI hope this helps if you have any further questions please let me know.
