Propositions 60, 90 and 110 are voter-approved amendments which allow qualifying homeowners to transfer the taxable value of a previous residence to a new residence. For many people, this can result in substantial tax savings. These amendments are effective until March 31, 2021.
Proposition 60, allows qualifying Sonoma County residents who are 55 years of age or older to transfer the base-year value of their original property to a replacement dwelling.
Proposition 90, extends the base-year value transfer provisions of a replacement dwelling located in another county if that county has an ordinance to allow such transfers. Sonoma County does not allow inter-county transfers.

Proposition 110, extends the base-year value transfer provisions to disabled persons of any age. In order to qualify, an owner of the property must be severely and permanently disabled.
Effective April 1, 2021, Propositions 60, 90 and 110 will be superseded by Proposition 19, passed by voters in the November 2020 election.
Proposition 19 allows persons who are 55 years of age or older or severely disabled to transfer the base year value of their principal residence anywhere in California within 2 years of the sale of the original property.
