Prop 19 and Your Inherited California Home: How to Keep Your Parents' Low Property Tax?

Short Answer

You may preserve your parents’ low property tax base if the inherited property was their principal residence and becomes your principal residence. You must also claim the Homeowners’ Exemption or Disabled Veterans’ Exemption within one year and file the appropriate Proposition 19 claim with the county assessor. However, reassessment may apply when the home’s fair market value exceeds the permitted value limit.

Introduction

California voters approved Proposition 19, formally called the Home Protection for Seniors, Severely Disabled, Families and Victims of Wildfire or Natural Disasters Act. This Constitutional Amendment substantially changed the property tax benefits available when children inherit real property from their parents.

Previously, children could inherit a principal home and certain additional real estate without a full reassessment. Today, the exclusion generally applies only to a qualifying family home or family farm. Consequently, careful inheritance planning can prevent unexpected property taxes and financial stress.

The Principal-Residence Requirement

To qualify for the parent-child exclusion, the property must have been the parent’s principal residence. After the transfer, at least one eligible child must occupy it as a primary residence.

The child should establish residency and claim either the Homeowners’ Exemption or Disabled Veterans’ Exemption within one year of the parent’s death or other qualifying transfer. If no eligible child moves into the home, the county assessor will generally treat the inheritance as a change in ownership and reassess the property at fair market value.

A limited grandparent-grandchild exclusion may also apply. However, the parents connecting the grandparents and grandchildren must generally be deceased on the transfer date.

How Proposition 19 Calculates the New Taxable Value

Proposition 19 does not guarantee that the entire tax base will transfer. Instead, it compares the property’s fair market value with the parent’s factored base year value plus a statutory allowance.

For qualifying transfers occurring from February 16, 2025, through February 15, 2027, that allowance is $1,044,586.

For example:

• Value within the limit: The child may retain the parent’s taxable value.

• Value above the limit: The amount exceeding the limit is added to the inherited tax base.

• No qualifying occupancy: The assessor may reassess the entire property at market value.

Therefore, families should obtain a reliable valuation before deciding whether a child should inherit, occupy, sell, or refinance the home.

Filing Deadlines That Heirs Should Not Miss

A qualifying child should complete the following steps:

1. Occupy the inherited home as a principal residence.

2. File for the Homeowners’ Exemption or Disabled Veterans’ Exemption within one year.

3. File Form BOE-19-P for a parent-child transfer.

4. Use Form BOE-19-G for an eligible grandparent-grandchild transfer.

5. Submit the claim to the county assessor where the property is located.

The exclusion claim should generally be filed within three years of the transfer or before the property is transferred to another person, whichever occurs first. Late filing may produce only prospective property tax relief.

Which Inherited Properties Qualify?

Inherited property	General Proposition 19 treatment
Parent’s principal home	May qualify if an eligible child occupies it and completes the required filings
Family farm or farmland	May qualify under the family-farm rules
Rental property	Generally does not qualify
Vacation home	Generally does not qualify
Investment property	Generally does not qualify
Commercial property	Does not qualify for the parent-child exclusion

A residential property used as a rental cannot qualify merely because the parent owned it. Likewise, converting the inherited principal home into a rental property may end the exclusion if no eligible child continues using it as a principal residence.

Trusts and Wills Do Not Automatically Avoid Reassessment

Placing a home in a trust does not independently preserve its property tax base. When a revocable trust becomes irrevocable at death and ownership passes to a beneficiary, the transfer may constitute a change in ownership.

A will, trust, deed, or probate order determines how title transfers. Proposition 19 separately determines whether the transfer qualifies for a property assessment exclusion. Therefore, an estate planning attorney should coordinate the trust administration, title transfer, occupancy requirements, and assessor filings.

Property Tax Basis Versus Income-Tax Basis

Property tax basis and federal income-tax basis are different concepts.

Proposition 19 controls the assessed value used to calculate California property tax. By contrast, inherited property generally receives a step-up in basis to its fair market value on the owner’s date of death, subject to applicable exceptions.

The step-up in basis may reduce capital gains taxes following a later sale. However, it does not prevent property tax reassessment under Proposition 19.

Mortgages and Inherited Homes

A low property tax base does not resolve mortgage issues. Heirs should separately examine:

• Existing mortgage payments

• Lender notifications

• Due-on-sale clause restrictions

• Insurance coverage

• Loan assumption

• Refinance or other financing

• Ownership and personal liability

Federal law limits enforcement of a due-on-sale clause for certain family and trust transfers. Nevertheless, heirs should address the loan before changing title or allowing payments to lapse.

Frequently Asked Questions

Can I keep my parents’ low property tax if I rent out the home?

Generally, no. At least one eligible child must use the inherited home as a principal residence. A rental property ordinarily does not qualify unless it meets the separate family-farm rules.

What happens if I move out after receiving the exclusion?

The exclusion may end when no eligible child uses the property as a principal residence. The county assessor can then establish a new taxable value.

Can several children inherit the home?

Yes. However, at least one qualifying child must occupy the home and claim the applicable homeowners’ exemption.

Does Proposition 19 eliminate capital gains taxes?

No. Proposition 19 addresses property tax reassessment. Capital gains taxes depend on the property’s income-tax basis and the circumstances of a later sale.

Conclusion: Protect the Family Home Before Deadlines Expire

Keeping a parent’s low property tax requires more than inheriting the home through a trust or will. The child must satisfy Proposition 19’s occupancy, value, filing, and timing requirements.
