Understanding California Proposition 19: Parent-Child Property Tax Transfers
What Proposition 19 Changed
California voters approved Proposition 19 in November 2020. It took effect on February 16, 2021 for intergenerational transfers. The measure replaced the prior parent-child and grandparent-grandchild property tax exclusion rules that had been in place under Propositions 58 (1986) and 193 (1996).
Under the prior rules, a parent could transfer a principal residence to a child with no property-tax reassessment, regardless of the property’s fair market value. A parent could also transfer up to $1 million of assessed value in other real property (such as rental property or vacant land) without triggering reassessment.
Proposition 19 narrowed the intergenerational exclusion to family homes that the transferee makes a principal residence. It eliminated the exclusion for other real property entirely. It also introduced a value-limit calculation: if the fair market value at transfer exceeds the factored base-year value plus an indexed amount, the property receives a partial increase in taxable value rather than full reassessment.
Which Family Transfers May Qualify
The Proposition 19 family-home exclusion may apply to:
- Parent-to-child transfers
- Child-to-parent transfers
- Grandparent-to-grandchild transfers, when every qualifying parent in the middle generation was deceased at the time of transfer
Other family relationships (siblings, aunts, uncles, cousins, in-laws) are not covered by the intergenerational exclusion. The relationship requirement is defined in California Constitution article XIII A, § 2.1 and Revenue and Taxation Code § 63.2.
Transferor and Transferee Principal-Residence Requirements
Two separate principal-residence requirements apply:
- Transferor: The property must have been the transferor’s principal residence (family home). If the transferor used it as a rental, investment property, or vacation home, the family-home exclusion generally does not apply.
- Transferee: The transferee must make the property a principal residence within one year of transfer. The transferee must also file for a homeowners’ or disabled-veterans’ exemption within one year. Merely inheriting the property does not satisfy this requirement.
How the Value Limit Works
When a transfer potentially qualifies for the family-home exclusion, the assessor compares the property’s fair market value at transfer against a value limit. The value limit equals the factored base-year value immediately before transfer plus an indexed amount.
The indexed amount is adjusted biennially based on the FHFA House Price Index for California. It is not an exemption amount standing alone. It is added to the property’s factored base-year value to establish the ceiling below which no increase in taxable value occurs.
The Current $1,044,586 Indexed Amount
For transfers or changes in ownership occurring between February 16, 2025 and February 15, 2027, the indexed amount is $1,044,586 (BOE Letter to Assessors 2025/009). Prior periods used different figures:
- February 16, 2021 through February 15, 2023: $1,000,000
- February 16, 2023 through February 15, 2025: $1,022,600
- February 16, 2025 through February 15, 2027: $1,044,586
Example: No Increase in Taxable Value
Example A
A parent’s home has a factored base-year value of $400,000. The parent passes away in 2026, and the home’s fair market value is $1,300,000. The child moves in and files for the homeowners’ exemption.
Value limit = $400,000 + $1,044,586 = $1,444,586
Fair market value ($1,300,000) does not exceed the value limit ($1,444,586).
Estimated adjusted taxable value: $400,000 (no increase).
The child may retain the parent’s lower assessed value.
Example: Partial Reassessment
Example B
Same facts, but the home’s fair market value is $2,000,000.
Value limit = $400,000 + $1,044,586 = $1,444,586
Excess above value limit = $2,000,000 – $1,444,586 = $555,414
Adjusted taxable value = $400,000 + $555,414 = $955,414
Estimated adjusted taxable value: $955,414.
Verification: $2,000,000 – $1,044,586 = $955,414.
The child receives a partial increase rather than full reassessment to $2,000,000.
Example: Likely Full Reassessment
Example C
A parent’s home has a factored base-year value of $400,000 and a fair market value of $1,800,000. The child inherits the property but uses it only as a rental. The child does not move in or file for a homeowners’ exemption.
Because the transferee does not make the property a principal residence, the family-home exclusion may not apply. The property may be fully reassessed to its $1,800,000 fair market value.
Illustration if fully reassessable: taxable value increases from $400,000 to $1,800,000.
Homeowners’ Exemption and Claim-Filing Concepts
Filing a Proposition 19 intergenerational transfer claim with the county assessor is different from filing for the homeowners’ or disabled-veterans’ exemption. Both may be required:
- Proposition 19 claim: Notifies the assessor that the transfer qualifies for the intergenerational exclusion. Filed on BOE-19-P or the county’s equivalent form.
- Homeowners’ or disabled-veterans’ exemption: Demonstrates that the transferee occupies the property as a principal residence. Filed separately.
The general claim period does not cure a failure to meet the separate principal-residence exemption deadline. Both deadlines should be tracked independently.
Trust and Multiple-Beneficiary Complications
Not every trust distribution constitutes the same type of change in ownership, and not every distribution occurs on the same date. The change-in-ownership event depends on the trust terms, the trustee’s actions, and the nature of the distribution. A trust transfer should not be assumed to be exempt from change-in-ownership rules without review of the governing instrument.
When multiple beneficiaries inherit a family home, each beneficiary’s occupancy and exemption status may affect whether the exclusion applies to their interest. Attorney review is recommended for trust transfers and multiple-beneficiary situations.
Why the Assessor’s Fair Market Value Matters
The county assessor determines the property’s fair market value at the time of the change in ownership. This determination drives the value-limit calculation. An appraisal supplied by the property owner is evidence, but the assessor may arrive at a different conclusion. If the assessor’s fair market value is higher than expected, the resulting taxable-value increase may be larger than the owner anticipated. Assessment appeals are available, but involve separate deadlines and procedures.
Why an Inherited Rental or Second Home Usually Presents a Different Result
The Proposition 19 family-home exclusion is limited to the transferor’s principal residence that the transferee also makes a principal residence. Property that was used by the transferor as a rental, vacation home, or investment property does not qualify as the transferor’s family home. Similarly, if the transferee intends to use the inherited property as a rental or second home rather than a principal residence, the exclusion requirements are generally not met. In either situation, the property may be subject to full reassessment at fair market value.
A separate exclusion for family farms may apply to qualifying agricultural property, but involves additional rules and fact-specific analysis that should be reviewed by an attorney.
Proposition 19 for Ventura, Santa Barbara, and Los Angeles County Families
Property tax reassessment rules under Proposition 19 apply statewide, but county assessor practices can vary. Families in Ventura County, Santa Barbara County, and Los Angeles County each deal with their own assessor’s office for filing Proposition 19 claims, requesting homeowners’ exemptions, and contesting assessments through the county Assessment Appeals Board.
Los Angeles County has specific procedural rules for supplemental and escape assessment appeals, including an alternative deadline measured from the tax bill mailing date rather than the assessment notice date (Rev. & Tax. Code § 75.31(c)(2), § 1605(c)). Families in any of these counties who have inherited or expect to inherit a family home should confirm the applicable deadlines and procedures with the county or an attorney.
Ridley Law serves families throughout Ventura, Santa Barbara, and Los Angeles Counties with Proposition 19 planning and post-transfer compliance.
Frequently Asked Questions
What did Proposition 19 change about parent-child property tax transfers?
Proposition 19 replaced the prior parent-child exclusion (Proposition 58) effective February 16, 2021. Under the prior rules, a parent could transfer a principal residence to a child with no reassessment regardless of value, plus up to $1 million of assessed value in other real property. Proposition 19 limited the exclusion to family homes the transferee makes a principal residence and eliminated the exclusion for other real property.
Which family members qualify for the Proposition 19 exclusion?
Parents and children (in both directions), and grandparents and grandchildren when the qualifying parent in the middle generation was deceased at the time of transfer. Siblings, in-laws, aunts, uncles, and cousins are not covered.
What is the current indexed amount, and how does it work?
For transfers between February 16, 2025 and February 15, 2027, the indexed amount is $1,044,586. This amount is added to the property’s factored base-year value to establish a value limit. If the fair market value at transfer does not exceed the value limit, there may be no increase. If it exceeds the limit, only the excess above the limit is added to the taxable value.
Does the transferee have to live in the inherited property?
Generally, yes. The transferee must make the property a principal residence within one year of transfer and must file for a homeowners’ or disabled-veterans’ exemption within one year. Inheriting the property alone does not satisfy this requirement.
What happens if the fair market value exceeds the value limit?
The property receives a partial increase. The adjusted taxable value equals the prior factored base-year value plus the excess of fair market value above the value limit. For example, with a $400,000 base-year value and $2,000,000 fair market value, the excess above the $1,444,586 value limit is $555,414, resulting in an adjusted taxable value of $955,414.
Is filing the Proposition 19 claim the same as the homeowners’ exemption?
No. They are separate filings. The Proposition 19 claim tells the assessor the transfer qualifies for the intergenerational exclusion. The homeowners’ exemption shows the transferee occupies the property as a principal residence. Both may be necessary.
Do trust transfers automatically qualify?
No. A trust transfer must constitute a change in ownership, and the timing of that change depends on the trust terms and the trustee’s actions. Not every distribution occurs on the date of death. Trust transfers should be reviewed to confirm eligibility and the applicable transfer date.
Can multiple children all receive the exclusion for one property?
When multiple children inherit a family home, each child’s occupancy and exemption status may affect whether the exclusion applies to their interest. If some children will not occupy the property, the exclusion may not apply to their share. This situation should be reviewed by an attorney.
What if the property was a rental or second home, not the parent’s residence?
The family-home exclusion requires that the property was the transferor’s principal residence. Rental property, investment property, and vacation homes generally do not qualify. A separate family-farm exclusion exists but requires additional fact-specific analysis.
Why does the assessor’s fair market value matter?
The county assessor determines fair market value at the time of the change in ownership. This drives the value-limit calculation and determines whether the property receives no increase, a partial increase, or full reassessment. An owner-provided appraisal may not be accepted. Assessment appeals are available if the owner disagrees with the assessor’s value.
