A homeowner called me and said, “Dar, I’m downsizing, but I’m terrified my property taxes will jump.”
That fear is real in California. The good news is Proposition 19 can save you a significant amount of money, but only if you understand the rules. If it is handled incorrectly, you can end up with higher taxes instead of lower taxes.
Here is the simple version.
Proposition 19, passed in 2020, lets certain homeowners transfer their property tax assessed value, your tax basis for property taxes, from one home to another. It is a California only rule, and if you qualify, it can apply in any county in California.
This matters because of Proposition 13. Many longtime homeowners have an assessed value that is much lower than today’s market value. So when you move, your property taxes can change dramatically. Proposition 19 is one of the few tools that can reduce that shock.
So who qualifies. At a high level, Proposition 19 can apply if you are 55 or older, severely and permanently disabled, or impacted by certain wildfire or disaster situations. And here is something most people do not know. For the 55 plus and disability categories, you can generally use it up to three times.
Now here is the mistake that creates the biggest surprise. People say, “I am transferring my taxes.” That is not exactly accurate. You are transferring your assessed value for the base property tax calculation, but your total bill can include special assessments.
That is why Mello Roos matters. In many cases, Mello Roos and other assessments do not transfer the way your assessed value does. So if your current home has no Mello Roos and your replacement home does, your total tax bill may be higher than you expected, even if you did the transfer correctly.
Here is the first practical step before you do anything. Pull your most recent property tax bill and separate it into two parts, base property tax and special assessments. That one step prevents a lot of mistakes.
One more important rule, timing. There is generally a two year window requirement, meaning the sale of your original home and the purchase of the replacement home typically need to happen within two years of each other. There are also filing steps and other restrictions, so this is not something you want to guess on.
If you are downsizing, Proposition 19 can be a huge advantage, but you need to understand who qualifies, what transfers, what does not transfer like Mello Roos, and the timing window.
Frequently Asked Questions
Who qualifies for a Proposition 19 base-year value transfer?
Homeowners who are 55 or older, severely disabled, or whose home was substantially damaged by a wildfire or natural disaster can generally transfer the taxable value of their primary residence to a replacement primary residence.
Can I move to a different county and keep my tax base?
Yes. Proposition 19 allows the transfer to a replacement home anywhere in California, not just within the same county.
How many times can I use Proposition 19?
Homeowners who qualify based on age or severe disability can use it up to three times in their lifetime.
How long do I have to buy the replacement home?
The replacement home generally must be purchased or newly constructed within two years of the sale of the original home, before or after.
What happens if the replacement home costs more than my old home sold for?
The transfer still works, but the difference in value is added to the tax base you carry over, so your property tax bill will be higher than it was on the old home.
How do I claim the transfer?
You file a claim with the county assessor where the replacement home is located. File promptly after you buy, and keep records of both sale and purchase dates and prices.
