What Homeowners Need to Know About Proposition 19

If you're a California homeowner thinking about downsizing, moving closer to family, or purchasing a replacement home, you may be able to keep one of your biggest financial advantages—your lower property tax bill.

Thanks to California Proposition 19, many eligible homeowners can transfer the taxable value of their current home to a replacement residence, potentially saving thousands of dollars every year.

Here's what you need to know.

What Is a Property Tax Base Transfer?

Your property's tax base is the assessed value used to calculate your annual property taxes under California's Proposition 13.

Normally, when you buy another home, the county reassesses the property at its current market value, often resulting in significantly higher property taxes.

Proposition 19 allows many eligible homeowners to transfer their existing taxable value to another primary residence anywhere in California, helping preserve lower property taxes.

Who Qualifies?

You may qualify if you are:

• Age 55 or older
• Severely disabled
• A victim of a natural disaster such as wildfire

Eligible homeowners may transfer their tax base up to three times (natural disaster victims are not subject to this limit), provided they meet the legal requirements.

Can You Buy a More Expensive Home?

Yes.

One of the biggest improvements under Proposition 19 is that you can purchase a replacement home that costs more than your current home.

If the replacement property is more expensive, an adjustment is made to your taxable value according to the Proposition 19 formula. While your assessed value may increase, it can still be substantially lower than a full reassessment at market value.

Why Proposition 19 Matters

For many Orange County homeowners, property taxes have remained low because they've owned their homes for decades.

Without Proposition 19, moving could dramatically increase annual property taxes.

With careful planning, many homeowners can:

• Downsize without losing all of their tax savings
• Move closer to family
• Purchase a home with fewer stairs
• Relocate anywhere in California
• Maintain greater financial flexibility during retirement

Important Deadlines

To qualify, the replacement home generally must be purchased or newly constructed within the time period specified by California law. Additional filing requirements also apply.

Because eligibility depends on individual circumstances, consult your county assessor or a qualified tax professional before making decisions.
