Prop 19 California 2026: Inheritance Rules & Filing Deadlines

How to keep your parent's low property tax rate when inheriting their home

What Is Prop 19 and Why Does It Matter for Your Inheritance?

Proposition 19, passed by California voters in November 2020, dramatically changed how property taxes work when children inherit their parents' homes. Before Prop 19, children could inherit any property from their parents—primary residence, rental properties, vacation homes—and keep the low Prop 13 assessed value.

That's no longer the case.

Under Prop 19, the parent-child exclusion is now limited to the parent's primary residence, and only if the child uses it as their own primary residence. Miss the deadlines or fail to meet the requirements, and you could face a property tax increase of $10,000 to $30,000+ per year.

The 4 Requirements to Qualify for Prop 19 Parent-Child Exclusion

To keep your parent's low property tax rate under Prop 19, you must meet ALL four requirements:

1. Primary Residence Requirement

The property must have been your parent's primary residence at the time of transfer (death). You cannot claim the exclusion for:

• Rental properties (even if parent previously lived there)
• Vacation homes or second homes
• Commercial real estate
• Vacant land

2. Child Must Use as Primary Residence

The inheriting child must establish the property as their own primary residence within 1 year of the date of transfer. This means:

• Moving into the home within 12 months
• Filing a homeowner's exemption at this address
• Updating driver's license and voter registration
• Actually living there (not just claiming it)

3. File BOE-19-P Within Deadline

You must file Claim for Reassessment Exclusion for Transfer Between Parent and Child (BOE-19-P) with your county assessor:

• Deadline: Within 3 years of date of death, OR
• Before the property is sold (whichever comes first)
• Filing late means losing the exclusion entirely

4. $1 Million Exclusion Cap

The exclusion is capped at $1 million of value difference. If the market value exceeds the assessed value by more than $1 million, you'll still face some reassessment.

Scenario	Assessed Value	Market Value	Child's New Assessed Value
Under $1M difference	$300,000	$1,100,000	$300,000 (no change)
Over $1M difference	$300,000	$1,800,000	$800,000 ($300K + $500K excess)
Significantly over $1M	$200,000	$2,500,000	$1,500,000 ($200K + $1.3M excess)

Prop 19 Filing Timeline: Critical Dates After Parent's Death

When a parent passes away, the clock starts ticking on multiple Prop 19 deadlines. Missing any of these can cost your family hundreds of thousands of dollars over time.

Deadline	What Must Happen	Consequence of Missing
Within 1 year	Child must move into property as primary residence	Permanent loss of Prop 19 exclusion
Within 1 year	File homeowner's exemption at new address	May jeopardize exclusion claim
Within 3 years	File BOE-19-P with county assessor	Permanent loss of exclusion
Before sale	Must file BOE-19-P before selling	Cannot retroactively claim

What About Multiple Children Inheriting Together?

When parents leave their home to multiple children, Prop 19 creates complicated situations:

Planning ahead with a living trust can address these situations by:

• Directing the home to the child who will live there
• Equalizing inheritances with other assets or life insurance
• Including buyout provisions with specific timelines
• Providing clear instructions to avoid family disputes

Properties That Do NOT Qualify for Prop 19 Exclusion

Be aware that these property types will be fully reassessed to market value upon inheritance:

• Rental properties — Even single-family homes being rented
• Vacation homes — Second residences, cabins, beach houses
• Investment real estate — Apartment buildings, commercial property
• Vacant land — Undeveloped parcels
• Properties where child won't live — Even if parent lived there

Prop 19 Planning Strategies: What You Can Do Now

While Prop 19 significantly limited the parent-child exclusion, there are still legitimate strategies to minimize property tax impact:

Strategy 1: Gift Property While Living (With Caution)

Transferring property before death isn't subject to Prop 19's restrictions, but:

• May trigger reassessment anyway (different rules apply)
• Loses stepped-up basis for capital gains
• Counts against lifetime gift/estate tax exemption
• Consult with tax attorney before attempting

Strategy 2: Structure Trust for Prop 19 Compliance

A properly drafted living trust can include:

• Clear instructions for filing BOE-19-P
• Direction of residence to specific child who will live there
• Equalization provisions using other assets
• Timeline requirements matching Prop 19 deadlines

Strategy 3: Life Insurance for Non-Residence Children

If only one child will use the home as primary residence:

• Leave home to that child through trust
• Purchase life insurance to provide equal inheritance to other children
• Avoids forced sale or exclusion loss

Strategy 4: Consider Property's Future Use

Before parents pass, families should discuss:

• Which child (if any) wants to live in the home?
• Is keeping the low property tax rate worth the residency requirement?
• Would selling and dividing proceeds be better financially?
