Prop 13 vs Prop 19: What Happens to Your Property Taxes When You Sell (2026 Rules)

When you sell your California home, the new buyer's property taxes reset to approximately 1% of the current purchase price — not the assessed value you have been paying. If you bought your Palmdale home in 2015 for $250,000, your annual property tax is roughly $2,850. The buyer who purchases it at $485,000 will pay approximately $5,530 per year — nearly double. This reassessment is the single biggest hidden cost of buying a home in California, and Prop 19 offers a powerful tax-base transfer option for sellers 55 and older.

Prop 13 Basics: How Property Tax Works in California

• Assessed value is set at purchase price (not market value).
• Annual increase is capped at 2% per year — regardless of how fast market values rise.
• Base tax rate is 1% of assessed value, plus local bonds and assessments (typically 0.15–0.30% additional).
• Reassessment to current market value triggers upon: sale/transfer, new construction, or change of ownership.
• This means long-time homeowners pay dramatically less in property tax than new buyers of identical homes.

What Happens to Property Taxes When You Sell

Prop 19: The Tax-Base Transfer for 55+ Sellers

Prop 19 (effective April 2021) allows homeowners aged 55 or older, severely disabled, or victims of natural disasters to transfer their Prop 13 tax base to a new home anywhere in California — up to 3 times in their lifetime. This is a game-changer for older AV homeowners who want to downsize or relocate. Before Prop 19, you could only transfer within the same county or to a few participating counties. Now you can buy in any California county.

How the Prop 19 Transfer Calculation Works

If your new home costs the same or less than your old home, your tax base transfers directly. If the new home costs more, the difference is added to your existing tax base. Example: your Palmdale home has a $283,000 assessed value. You sell for $485,000 and buy a new home for $400,000 (less than sale price). Your new assessed value = $283,000 (your old basis transfers entirely). If you buy for $550,000 instead, your new assessed value = $283,000 + ($550,000 - $485,000) = $348,000. The tax base transfer must be filed within 2 years of the sale.

Prop 19 and Inherited Property: What Changed

Prop 19 also significantly changed inherited property rules. Before 2021 (under Prop 58), children could inherit their parents' low Prop 13 tax base on any property — primary residence or investment. After Prop 19, the tax base is only preserved if the child uses the inherited home as their primary residence AND the home's market value does not exceed the assessed value by more than $1 million. Investment and rental properties inherited after February 2021 are reassessed to current market value. This change particularly impacts AV families who planned to keep rental properties in the family with low tax bases.

Should Prop 13 Savings Prevent You From Selling?

Many long-time AV homeowners stay in homes that no longer fit because they fear losing their low tax base. This is the Prop 13 golden handcuffs problem. But the math often favors selling: if your home has appreciated $200,000+ and you are 55+, Prop 19 lets you take your tax base with you. Even if you are under 55, the equity freed by selling — combined with a smaller or better-located home — often offsets the higher property taxes within a few years.
