Property Tax Transfer in California: What Keeps Your Base
“Property tax transfer” in California means two different things, and people search for both. One is moving your own low Proposition 13 tax base to a new home when you move. The other is transferring the property itself to someone else — a spouse, a child, a trust — without triggering a reassessment. Both come down to the same idea: keeping the low base-year value instead of resetting it to today's market price.
Here's how each works, what keeps your base, and what resets it — with links to the governing law.
For the full legal detail behind each rule below, see the California reassessment law guide.
1. Moving your low base to a new home (Prop 19)
If you're 55 or older, severely disabled, or a disaster victim, Proposition 19 lets you carry your existing base-year value to a replacement home anywhere in California — instead of being assessed at the new home's full price. For a long-held home, that can save thousands of dollars a year. You can do it up to three times (no limit for disaster victims), and if the replacement costs more, the difference is added to your transferred base.
2. Transferring the property without resetting the base
Passing the property itself to someone else keeps your low base only when the transfer is one California specifically excludes from reassessment:
- To a spouse — fully excluded, no value cap (including on divorce or death).
- To a child (Prop 19) — only if the child makes it their primary residence, and only up to a value cap.
- Into your own revocable living trust — not a change of ownership while you remain the present beneficiary.
- To an LLC or corporation you own in the same proportions — excluded because your ownership share doesn't really change.

3. A genuine sale resets the base
When property is sold to an unrelated buyer, that is a change of ownership: it's reassessed to the purchase price, and the buyer's tax is based on what they paid. There is no way to carry the seller's low base to a buyer — which is exactly why a new owner usually pays much more than the person they bought from.
Owners vs. buyers
A seller's current (low) bill is not what a buyer will pay. See why owners and buyers are taxed so differently.
Frequently Asked Questions
Can I transfer my property tax base to a new house in California?
Yes, if you qualify. Under Proposition 19, homeowners who are 55 or older, severely disabled, or victims of a wildfire or natural disaster can transfer their existing base-year value to a replacement home anywhere in California, up to three times. If the new home costs more, the difference is added to the transferred value. This replaced the older Propositions 60, 90, and 110.
Does transferring property to a family member reset the property tax?
It depends who and how. Transfers between spouses are fully excluded (no reassessment, no cap). A transfer to a child can be excluded under Proposition 19 only if the child makes the home their primary residence, and only up to a value cap. Funding your own revocable living trust is not a change of ownership. A transfer that genuinely changes beneficial ownership to an unrelated person is reassessed.
Does selling a house reset the property tax in California?
Yes. A sale to an unrelated buyer is a change of ownership, so the property is reassessed to the purchase price and the buyer's tax is based on what they paid — which is why a new buyer often pays much more than the previous owner did. That reassessment can't be avoided on a genuine sale.
Is transferring property tax the same as transferring the deed?
No. Transferring the deed (title) moves ownership of the property; whether that resets the tax depends on the change-in-ownership rules. Transferring your tax base (Prop 19) keeps your low assessed value and moves it to a different home you buy. They're separate things people often lump together.
How many times can I transfer my property tax base under Prop 19?
Up to three times for a homeowner who is 55 or older or severely disabled. There is no three-transfer limit for victims of a wildfire or other natural disaster.
