Proposition 19 & Your California Property Taxes: 2026 Buyer and Heir Guide
Short answer: Proposition 19 lets California homeowners who are 55 or older (or severely disabled, or wildfire/disaster victims) transfer their low Proposition 13 property tax base to a replacement home anywhere in the state, up to three times — but it also reassesses most inherited property to full market value unless the child moves in as their primary residence. For buyers, this affects your real monthly cost; for families, it changes inheritance planning. Here's how both sides work in 2026.
The Proposition 13 foundation
California property taxes are based on assessed value, not current market value. Under Proposition 13 (1978), the base rate is 1% of assessed value and annual increases are capped at 2% — though local bonds push the effective rate to roughly 1.1%–1.3%. When a property changes ownership, it's reassessed to current market value, which is why a new buyer often pays far more tax than a long-time neighbor in an identical home. This reassessment is a real part of your payment — factor it into our mortgage calculator when estimating your monthly cost.
The senior benefit: base-year transfer
If you're 55 or older, Prop 19 is a major opportunity. You can sell your current home and transfer its low taxable base to a replacement home anywhere in California, up to three times in your lifetime. This removes the old "tax penalty" that discouraged downsizing or moving closer to family. With many California seniors sitting on $500,000–$1 million+ in equity, this creates a real window to sell and buy — especially relevant for reverse mortgage and downsizing decisions.
The inheritance change heirs need to know
Prop 19 sharply narrowed the parent-child exclusion. Before, children could inherit property and keep the low tax base, including rentals and second homes. Now: rentals and vacation homes are fully reassessed to market value at transfer, with no exclusion. The family home keeps a limited exclusion only if the child makes it their primary residence within one year, and even then there's a value cap (roughly $1 million above the original base). This can raise an heir's property tax dramatically.
How it affects buyers right now
As a new buyer in 2026, you're reassessed at full market value, so you lock in today's higher tax baseline for the life of your ownership. On a $1.4 million home at a ~1.15% effective rate, that's about $16,000 a year in property tax — a number that belongs in your affordability math alongside the mortgage. First-time buyers especially should budget for it; see our California first-time buyer programs for help offsetting upfront costs.
Watch the 2026 ballot
A repeal effort targeting Prop 19's inheritance rules has been gathering signatures and could appear on the November 2026 ballot. Nothing is settled, and the current restrictive rules remain the law until any change passes. If you're planning an inheritance or a base-year transfer, talk to a tax professional and don't rely on a repeal that may not happen.

Worked example: a 55+ base-year transfer
A homeowner over 55 has an assessed value of $250,000 on a home that sells for $1,200,000. They buy a replacement for $1,500,000. Because the new home costs more than the old one sold for, the difference is added to the transferred base. Illustrative numbers at a ~1.15% effective rate:
| Scenario | Assessed value | Yearly tax |
|---|---|---|
| Transferred base + $300,000 difference | $550,000 | ~$6,325 |
| No transfer (full reassessment) | $1,500,000 | ~$17,250 |
Timing matters. The sale and the purchase generally must happen within two years of each other, and you file a claim with the county assessor. The Board of Equalization publishes the rules.
Mortgage questions heirs run into
- Keeping the existing loan. Federal law generally lets a relative who inherits the home keep the existing mortgage without the lender calling it due.
- Buying out siblings. If one heir keeps the home, a cash-out refinance or purchase loan can pay the others their share.
- Higher tax after reassessment. If the property is reassessed, the new tax bill changes your payment and what you qualify for.
Lenders qualify you on the full payment, including the new tax line, so get an estimate early.
Financing a downsize after 55
Prop 19 makes moving cheaper on taxes, but you still need to fund the purchase. If the replacement costs the same or less than the old home sold for, the transferred base generally stays at the old value. Common paths: pay cash from the sale, use a conventional loan, or, if you’re 62+, use a reverse mortgage for purchase, which requires the home to be your primary residence and HUD-approved counseling.

More questions
How long do I have to buy a replacement home under Prop 19?
Generally the purchase or new construction must be completed within two years before or after the sale of the original home. Confirm details with your county assessor before you list.
Do I have to file anything to keep my low tax base?
Yes. Base-year transfers and the family-home exclusion both require a claim filed with the county assessor, and deadlines apply. A tax professional can help with the forms.
