California’s Proposition 19 changed how property taxes carry over when a home changes hands. Voters passed it in November 2020, and its rules have applied since early 2021. If you are considering a move after 55, or thinking about passing a home to your children, Proposition 19 affects the property tax bill that follows the home. This guide explains the main provisions in plain terms so you can plan with your tax advisor and the county assessor.
What Proposition 19 changed
Under Proposition 13, a home’s assessed value, the figure your property tax is based on, rises only a little each year until the home is sold or transferred, at which point it is usually reassessed to market value. Proposition 19 kept that framework but rewrote two parts of it: the ability of older and disabled owners to carry their assessed value to a new home, and the ability of parents to pass a low assessed value to their children. One change opened up more flexibility for move-up and move-down buyers. The other narrowed a long-standing break for inherited property.
Moving after 55: taking your tax base with you
If you are 55 or older, severely disabled, or a victim of a wildfire or other declared disaster, Proposition 19 lets you transfer the factored base year value of your current primary residence to a replacement primary residence anywhere in California. This has applied since April 1, 2021. You can use this benefit up to three times if you qualify by age or disability. If the replacement home costs more than the price your old home sold for, the difference is added to your transferred value, so you keep most of your tax savings rather than starting over at full market value. For an Orange County owner who bought decades ago, this can mean a much smaller tax bill on a new home than a fresh purchase would carry.
Passing a home to your children
Proposition 19 tightened the parent-to-child transfer rules that many families had counted on. Today, a child can keep the parent’s assessed value only if the home was the parent’s primary residence and the child makes it their own primary residence, and files for the homeowners’ exemption. Even then, the protection is capped. For transfers between February 16, 2025 and February 15, 2027, the excluded amount is the home’s factored base year value plus $1,044,586. Value above that cap is reassessed. The dollar figure is adjusted for inflation every two years by the State Board of Equalization. Property that a child does not move into, such as a second home or a rental, is reassessed to market value.
What this means for Orange County homeowners
The practical takeaways are straightforward. If you are over 55 and have owned your Orange County home for a long time, you have real freedom to move without giving up your Proposition 13 tax base. If you plan to leave a home to your children, the old approach of simply passing it down no longer preserves the low tax bill unless a child lives there, and even a valuable primary residence can face partial reassessment. Because the numbers and deadlines matter, confirm the current figures and file the right forms with the county before you act.

Frequently Asked Questions
When did Proposition 19 take effect?
Voters approved Proposition 19 in November 2020. The parent-to-child transfer rules took effect on February 16, 2021, and the rules that let owners over 55 carry their tax base to a new home took effect on April 1, 2021. Both have been in force across California since then.
Can I move after 55 without losing my Proposition 13 tax base?
Yes. If you are 55 or older, severely disabled, or a disaster victim, you can transfer the assessed value of your primary residence to a replacement primary residence anywhere in California, up to three times. If the new home costs more than your old one sold for, the difference is added to your transferred value, so you keep most of your savings.
How much can my children inherit without reassessment?
For transfers between February 16, 2025 and February 15, 2027, a child can exclude the home’s factored base year value plus $1,044,586 from reassessment, and only if the child makes the home their primary residence. Value above that cap is reassessed to market value. The dollar limit is adjusted for inflation every two years.
What happens to an inherited rental or second home?
Proposition 19 removed the exclusion for property a child does not live in. An inherited rental, vacation home, or any residence the child does not make their primary home is reassessed to current market value, which usually raises the property tax bill.
Where do I confirm the current rules and file the paperwork?
The California State Board of Equalization publishes the current figures and forms, and your county assessor processes the claims. In Orange County, contact the Orange County Assessor. Because deadlines apply, confirm the details and file promptly, and consult a tax professional or attorney for your specific situation.
