Prop 19 Explained: Moving Your Property Tax Base Within California
Figures and rules in this post are as of November 6, 2026, from the sources linked below. Check the source for any later update.
Proposition 19, approved by California voters in November 2020, changed two property tax rules. These are the main points as the State Board of Equalization summarizes them.
Base year value transfers (since April 1, 2021)
- Available to homeowners age 55 or older, severely and permanently disabled homeowners, and victims of a wildfire or Governor-declared natural disaster.
- Applies to a principal residence. The replacement home can be anywhere in California and must be bought or built within 2 years of selling the original.
- Homeowners 55+ or disabled can use it up to three times.
- There is no cap on the replacement home’s price. If it costs more than the original’s adjusted market value (100% if bought before the sale, 105% within the first year after, 110% within the second year), the difference is added to the transferred base value.
- File with the Assessor in the county where the replacement home is, within 3 years. Forms: BOE-19-B (55+), BOE-19-D/DC (disabled), BOE-19-V (disaster victims).
Parent-child and grandparent-grandchild transfers (since February 16, 2021)
- The exclusion now covers only a family home that becomes the child’s principal residence (or a family farm).
- The exclusion is limited to the factored base year value plus an inflation-adjusted amount. That amount is $1,044,586 for transfers from February 16, 2025 through February 15, 2027.
- The child must file for the homeowners’ exemption within one year of the transfer.
These rules have more detail than this summary covers. A tax professional or attorney can apply them to a specific situation.
