What you should Know about 60/90
60 & 90: Propositions you, your friend, your mom, your mom’s friend and everyone in the county should know about! These two Propositions, 60 and 90, were passed in 1986 and 1988 to diminish property tax burdens for “senior citizens” looking to buy new property. You see in California when you buy a home, the property is reappraised and a new base tax is determined. However, with Propositions 60 and 90 or “60/90” persons 55 years or older can transfer their existing home for another home in a participating county of same or equal value and keep their original tax base!
