California Proposition 19: Inherited Property Tax Rules

California Proposition 19, effective February 16, 2021, significantly changed property tax rules for inherited real estate. Under the old rules, children could inherit a parent's home and keep the low property tax base indefinitely. Under Prop 19, major restrictions apply. This is an important consideration for anyone involved in California probate or estate planning.

This guide explains how Prop 19 affects inherited property and what heirs can do to minimize property tax increases.

What Changed with Proposition 19

Before Prop 19 (Pre-February 2021)

Parents could transfer a primary residence of any value to children with no property tax reassessment. Parents could also transfer up to $1 million in assessed value of other property (vacation homes, rentals) without reassessment.

Children received the property with the parent's low tax base, often resulting in property taxes far below current market value.

After Prop 19

The parent-child exclusion now requires:

The property must have been the parent's primary residence
The child must use it as their primary residence within one year
Only up to $1 million of market value above the assessed value is excluded

Non-primary residence property (rentals, vacation homes) is reassessed to full market value when inherited.

The New Rules in Detail

Primary Residence Requirement for Parents

For the exclusion to apply, the property must have been the transferor's (parent's or grandparent's) primary residence at the time of transfer or death.

A vacation home, rental property, or vacant land does not qualify, regardless of how long the parent owned it.

Primary Residence Requirement for Children

The heir must:

Use the property as their own primary residence
Move in within one year of the transfer
File a claim with the county assessor

If the heir does not meet these requirements, the property is reassessed to current market value.

The $1 Million Exclusion Limit

Even when both primary residence requirements are met, the exclusion is limited:

The new assessed value equals the old assessed value plus the difference between current market value and old assessed value, minus $1 million

Formula: New Assessed Value = Old Assessed Value + (Market Value - Old Assessed Value - $1,000,000)

If market value exceeds the old assessed value by more than $1 million, the excess is added to the assessed value.

Example Calculations

Example 1: Property within $1 million

Parent's assessed value: $200,000
Current market value: $900,000
Difference: $700,000 (less than $1 million)

Result: Child's assessed value = $200,000 (no increase)

Example 2: Property exceeding $1 million

Parent's assessed value: $200,000
Current market value: $1,500,000
Difference: $1,300,000 (exceeds $1 million by $300,000)

Result: Child's assessed value = $200,000 + $300,000 = $500,000

Example 3: Rental property (no exclusion)

Parent's assessed value: $300,000
Current market value: $1,200,000

Result: Child's assessed value = $1,200,000 (full reassessment)

Filing Requirements

Claim Form

To claim the exclusion, file a claim with the county assessor's office. The exact form varies by county but is typically titled "Claim for Reassessment Exclusion for Transfer Between Parent and Child."

Deadline

File the claim within one year of the transfer date (or death date).

If you miss the deadline, you may still file a late claim for the current year, but you lose the benefit for prior years.

Documentation Needed

Proof of relationship (birth certificate, adoption records)
Death certificate (if inherited)
Evidence that the property was the transferor's primary residence
Evidence that you will use it as your primary residence

Impact on Different Types of Property

Family Home (Primary Residence)

If both requirements are met (parent's primary residence + child's primary residence), the exclusion applies with the $1 million cap.

Rental Property

No exclusion. Fully reassessed to market value at transfer or death.

Vacation Home

No exclusion. Fully reassessed to market value.

Family Farm

Special rules may apply to farms. Consult a property tax specialist.

Commercial Property

No exclusion. Fully reassessed.

What Happens Without the Exclusion

When property is reassessed to current market value:

Scenario	Old Tax	New Tax
$300,000 assessed to $1,500,000	$3,000/year	$15,000/year
$200,000 assessed to $1,000,000	$2,000/year	$10,000/year
$150,000 assessed to $750,000	$1,500/year	$7,500/year

Based on approximately 1% effective property tax rate

The property tax increase can be thousands of dollars per year, making inherited property expensive to keep.

Planning Strategies

Before Parent's Death

Transfer during lifetime with retained life estate This strategy no longer provides the same benefit under Prop 19. Consult a tax professional.

Living trust planning Trusts do not change the Prop 19 analysis. The property is still reassessed at death unless requirements are met. See our guide on trust administration for more details.

Selling before death If children do not plan to use the home as their primary residence, selling before death may be better than inheriting and paying higher property taxes.

After Parent's Death

Move into the home If you can use the property as your primary residence within one year, do so to claim the exclusion.

Sell promptly If you cannot meet the primary residence requirement, consider selling before the property tax increase takes full effect.

Rent short-term while deciding You have one year to move in. Renting temporarily does not disqualify you if you move in within the year.

Interaction with Income Tax Step-Up

Prop 19 affects property taxes, not income taxes. The step-up in basis for income tax purposes still applies.

If you inherit and sell:

You receive a stepped-up basis at fair market value
Capital gains tax is minimal or zero if sold soon after death
Property tax would have increased but may not matter if you sell quickly

Grandparent-Grandchild Transfers

The parent-child exclusion extends to grandparents and grandchildren, but only if the child's parent (the middle generation) is deceased. This follows intestate succession principles.

If the parent is still alive, the grandparent cannot transfer directly to grandchildren with the exclusion.

Frequently Asked Questions

What is the deadline to file a Prop 19 claim?

One year from the date of transfer or death. File with the county assessor's office.

Can I inherit rental property without reassessment?

No. Prop 19 eliminated the exclusion for non-primary residence property. Rental properties, vacation homes, and other non-primary residence properties are reassessed to market value.

What if I inherit but live out of state?

If you cannot use the property as your primary residence within one year, you do not qualify for the exclusion. The property will be reassessed.

Does Prop 19 apply to property in a trust?
