Proposition 19 Explained: Moving at 55+, Inherited Homes & Property Taxes (2026–2027)

By Ramez Malki, Broker — C&R Properties  |  Updated October 26, 2026

Proposition 19 did two things. It made it easier for homeowners 55 and older, severely disabled homeowners and disaster victims to move and keep their low property tax base. And it made it harder for children to inherit a parent’s low tax base. If you’re an Orange County homeowner who has owned for decades, Prop 19 may be the single biggest factor in whether moving makes financial sense. This guide covers both sides, with current numbers and worked examples.

Part 1: Moving at 55+ (base-year value transfer)

Who qualifies

• Homeowners 55 or older (one spouse living in the home is enough)
• Homeowners who are severely and permanently disabled, at any age
• Victims of wildfire or a Governor-declared disaster whose home was substantially damaged

The rules

• Both the original and the replacement must be your principal residence.
• Buy or build the replacement within 2 years of selling the original, before or after.
• The replacement can be anywhere in California. Under the old rules only some counties accepted transfers.
• 55+ and disability claims can be used up to three times. Past claims under the old Props 60 and 90 don’t count.
• File the claim with the assessor in the county of the new home within 3 years of buying it: BOE-19-B for 55+, BOE-19-D or 19-DC for disability, BOE-19-V for disaster. Escrow doesn’t file it for you.

The “equal or lesser value” test: 100%, 105%, 110%

Early Prop 19 materials from 2021 said this part was unclear. It’s been settled since. A replacement is “equal or lesser value” if its price is no more than:

If the replacement costs more than the limit, you still get the transfer. The amount above the limit is simply added to your transferred taxable value.

Example 1: upsizing

Your Huntington Beach home has a taxable value of $400,000. You sell it for $900,000 and you had bought a $1,000,000 home in San Clemente before the sale. The limit is 100% of $900,000. The extra $100,000 is added: your new taxable value is $500,000, not $1,000,000. At roughly 1.1% that’s about $5,500 a year in property tax instead of about $11,000.

Example 2: downsizing

Your Irvine home has a taxable value of $350,000 and sells for $1,700,000. Six months later you buy a $1,150,000 single-level home in Laguna Woods. It’s under the 105% limit, so your taxable value stays $350,000. Paying property tax on $350,000 instead of $1,150,000 saves roughly $8,800 a year, and you free up more than $500,000 of equity before costs.

Sell first, buy first, or both at once?

• Buy first gives you the most control and one move, but the strictest value test (100%) and you’ll need financing to cover both homes for a while. A bridge loan, HELOC or cash-out on the current home can work; Lendia can structure this.
• Sell first unlocks your equity and gives you the 105% or 110% allowance, but you may need a rent-back or a short-term rental between homes.
• Simultaneous closings are common in Orange County: list your home with a contingency or a rent-back, then close on both in the same week.

Before you downsize, check HOA dues and special assessments for condos and 55+ communities. Lower property tax can be offset by $500 to $1,000+ a month in dues. Our 2027 HOA law guide covers what’s changing for condo owners.

Part 2: Inheriting a parent’s home (parent-child exclusion)

Before February 16, 2021, a parent could pass a home and up to $1 million of other property to a child with no reassessment at all, whether or not the child lived there. Prop 19 narrowed that.

Today’s rules

• The home must become the child’s principal residence. If the child rents it out or keeps it as a second home, it’s reassessed to market value.
• The child must file the homeowners’ exemption (BOE-266) within 1 year of the transfer, and the parent-child exclusion claim (BOE-19-P, or BOE-19-G for a grandparent when the parents have died) within 3 years or before selling to a third party.
• The exclusion is capped. The child keeps the parent’s taxable value plus up to $1,044,586 of the difference between that value and market value, for transfers between February 16, 2025 and February 15, 2027. (It started at $1,000,000 in 2021 and was $1,022,600 from 2023 to 2025.) The amount adjusts every two years; the next change is due February 16, 2027.
• Family farms have similar rules. Other inherited property, such as rentals, is reassessed.

Example 3: inheriting in Newport Beach

Mom’s home has a taxable value of $300,000 and is worth $1,600,000 at her death. Her daughter moves in. The difference is $1,300,000, which is $255,414 more than the $1,044,586 limit. The daughter’s new taxable value is $300,000 + $255,414 = $555,414, still far below market. If she rented it out instead, the taxable value would jump to $1,600,000, roughly $11,500 a year more in property tax than if she moved in.

New for 2027: special needs trusts

Starting in 2027, SB 974 lets a transfer through a properly set up special needs trust qualify as a parent-child (or grandparent-grandchild) transfer. That helps families planning for a child with a disability.

Part 3: Keep, rent or sell an inherited home?

If one heir wants to keep the home, they can often buy out the others with a cash-out refinance. Lendia finances heir buyouts. If the home is going through probate or a trust, see our probate and trust sales page.

Prop 19 planning checklist

1. Look up your current taxable value on your property tax bill.
2. Get a realistic sale price for your home (free home value).
3. Decide whether to buy first, sell first or close both at once, and line up financing.
4. Keep your closing dates within the 2-year window, and file BOE-19-B (or 19-D/19-V) within 3 years.
5. Parents: talk with an estate attorney about how Prop 19 affects your plan, including who’s likely to live in the home.
6. Heirs: decide within the first year whether you’ll move in, and file the homeowners’ exemption on time.

Frequently Asked Questions

How does Prop 19 work for seniors?

Homeowners 55 or older can sell their principal residence and transfer its taxable value to a replacement home anywhere in California bought within 2 years. If the new home costs more than the allowed limit, the difference is added to the transferred value. It can be used three times.

Can I use Prop 19 to buy a more expensive home?

Yes. You keep your old taxable value plus the amount by which the new home’s price exceeds 100%, 105% or 110% of your sale price, depending on when you buy.

Do I have to buy in the same county under Prop 19?

No. Prop 19 base-year transfers work between any of California’s 58 counties.

What is the Prop 19 parent-child exclusion amount for 2026?

$1,044,586 for transfers from February 16, 2025 through February 15, 2027, according to the California State Board of Equalization.

Will my inherited home be reassessed?

Yes, unless you make it your principal residence and claim the parent-child exclusion. Even then, value above the parent’s taxable value plus $1,044,586 is added to your assessment.

How do I file for a Prop 19 base-year transfer?

File the claim form (BOE-19-B for 55+, BOE-19-D or 19-DC for disability, BOE-19-V for disaster) with the assessor in the county of the replacement home within 3 years of the purchase.
