What Is Proposition 19 and How Can It Affect a Move?
By JC Pacific Corp Published 2026-09-01 Last professionally reviewed: September 2026
California Proposition 19 may allow certain homeowners to transfer a base-year property-tax value to a replacement principal residence, subject to eligibility, value, timing, filing, and county-assessor requirements.
Who may qualify?
The rules apply to specified categories of homeowners, including certain people who are:
- Age 55 or older
- Severely disabled
- Victims of qualifying wildfires or natural disasters
The law also changed rules affecting some parent-child and grandparent-grandchild property transfers.
Is the transfer automatic?
No. Eligible owners must follow applicable procedures and submit required claims and documentation. Replacement-property value can affect the transferred taxable value.
Is Proposition 19 an income-tax exclusion?
No. It concerns California property-tax base-year value. Capital-gains tax and the federal home-sale exclusion are different issues.
The California Board of Equalization's Proposition 19 page is the official starting point for current rules, forms, and deadlines.
Frequently Asked Questions

Can the benefit be used more than once?
Eligible homeowners in certain categories may have multiple transfers available, while disaster-related rules differ. Verify current requirements.
Does buying outside California qualify?
A replacement property outside California does not receive a California property-tax base transfer.
