Yes, property taxes usually go up on an inherited California house, unless a child makes it their principal residence within one year. Under Proposition 19, a child who moves in and files for the homeowners’ exemption can keep the parent’s taxable value, up to the parent’s factored base-year value plus $1,044,586 for transfers from February 16, 2025 through February 15, 2027. If no child moves in, the home is generally reassessed to market value.
Proposition 19 is the ballot measure that changed how parent-child transfers are taxed, starting with transfers on or after February 16, 2021, according to the BOE Prop 19 Fact Sheet. It limits the old tax break to the family home, and only when the child lives there.
The one thing most families get wrong is assuming the parent’s low tax bill passes to the kids no matter what. It does not. A home kept as a rental or left empty generally gets a new, higher assessed value.
Key Facts
- Proposition 19 applies to parent-child transfers on or after February 16, 2021.
- The Prop 19 family home exclusion requires the home to have been the parent’s principal residence.
- The child must make the home a principal residence and file for the homeowners’ exemption within one year to get the benefit from the transfer date.
- For transfers from February 16, 2025 through February 15, 2027, the Prop 19 exclusion covers the factored base-year value plus $1,044,586.
- Under Prop 19, market value above the cap is added to the taxable value.
- The Prop 19 claim form, BOE-19-P, must be filed within three years of the transfer or before the home is transferred to a third party, whichever is earlier.
- The Prop 19 cap is next adjusted on February 16, 2027.
What Did Prop 19 Change for Inherited Homes?
Prop 19 narrowed the parent-child tax break to the family home and added a value cap. For transfers on or after February 16, 2021, a child keeps the parent’s taxable value only when the child lives in the home. Transfers before that date followed older rules, so ask your county assessor which rules apply if your parent died earlier.
The key question is the transfer date. For an inherited home, the date of death is the date of change in ownership, so the law in effect on that date applies, according to the BOE’s Prop 19 questions and answers.
Who Qualifies for the Prop 19 Parent-Child Exclusion?
A child qualifies when three conditions are met. The BOE Fact Sheet lists them:
- The home was the parent’s principal residence.
- The child makes it the child’s own principal residence within one year.
- The child files for the homeowners’ exemption, or the disabled veterans’ exemption, within one year.
A principal residence is the home where a person actually lives most of the time. If the child files the exemption late, the benefit starts only from that year forward, not from the transfer date.
How Is the $1,044,586 Cap Calculated?
The cap equals the parent’s factored base-year value plus $1,044,586, for transfers from February 16, 2025 through February 15, 2027. The factored base-year value is the parent’s taxable value under Proposition 13, with the small yearly increases the law allows. For a home bought decades ago, it is often far below market value.
If the home’s market value is at or under the cap, the child keeps the parent’s taxable value. If market value is higher, the amount above the cap is added to the parent’s taxable value. The cap has changed every two years:
- February 16, 2021 to February 15, 2023: $1,000,000
- February 16, 2023 to February 15, 2025: $1,022,600
- February 16, 2025 to February 15, 2027: $1,044,586
The next adjusted amount takes effect February 16, 2027. Check the BOE’s Prop 19 page for the current figure before you run the math.
What Happens If You Rent the House or Leave It Empty?
A home that no child uses as a principal residence generally does not qualify for the exclusion. It is then reassessed as a change in ownership, based on market value. Confirm the result for your property with the county assessor.
For many long-held Sacramento-area homes, that can mean a much larger tax bill. Before choosing to rent, compare the rent against the new tax bill in Should You Keep, Rent or Sell an Inherited House?
An empty house carries other costs too. Many insurers limit coverage after 30 or 60 days of vacancy, as covered in What Should You Do With a Vacant Inherited House?
What If Several Siblings Inherit the House?
Not every child has to move in. The BOE’s Prop 19 questions and answers say the exclusion should be allowed as long as at least one child who received the home lives there and files for the homeowners’ or disabled veterans’ exemption within one year, and all other requirements are met. Ask the county assessor how that applies before the heirs decide who keeps the house.
A buyout between siblings can also create its own change in ownership. Talk with a probate attorney before signing a buyout, and see What If Siblings Disagree About Selling the Inherited House?
How and When Do You File the BOE-19-P Claim?
File form BOE-19-P with your county assessor within three years of the transfer, or before the home is transferred to a third party, whichever comes first. That deadline comes from the BOE-19-P claim form. A late claim is allowed within six months after the assessor mails a notice of supplemental or escape assessment.
The homeowners’ exemption is a separate filing with its own one-year window. Filing both early protects the benefit back to the transfer date.
Does Prop 19 Matter If You Plan to Sell?
It matters less, but it still affects the bills while the estate owns the house. A sale to an outside buyer ends the family’s tax question, because the buyer’s own purchase sets the new assessment.
During probate, the house can sell once the court issues letters to the personal representative, the person the court appoints to run the estate. Read Can You Sell a House While It’s in Probate in Sacramento? for that process. Heirs who sell also want to understand the stepped-up basis, explained in Do You Pay Capital Gains Tax When You Sell an Inherited House?
What Does Prop 19 Look Like With Real Numbers?
Illustrative example, not a real client.
A parent dies in 2026, leaving a long-held home in Placer County to one child. The parent’s factored base-year value is $185,000, and the home’s market value at death is $1,300,000. The child moves in and files for the homeowners’ exemption within one year.
- Cap: $185,000 + $1,044,586 = $1,229,586
- Amount over the cap: $1,300,000 – $1,229,586 = $70,414
- New taxable value: $185,000 + $70,414 = $255,414
The child’s taxable value rises from $185,000 to $255,414, not to the full $1,300,000. That keeps $1,044,586 of value off the tax roll. To estimate the bill, multiply each value by the tax rate shown on the county tax bill.
Change one fact: the home’s market value at death is $650,000.
- $650,000 is below the $1,229,586 cap.
- New taxable value: $185,000, the same as the parent’s.
If the child in this version rents the house instead of moving in, the home generally does not qualify. The taxable value would then be reassessed to about $650,000.
What Mistakes Should You Avoid?
- Missing the one-year move-in and exemption deadlines. A late homeowners’ exemption gives relief only from that year forward.
- Assuming a rental keeps the parent’s tax value. A home that is not a child’s principal residence is generally reassessed.
- Forgetting the BOE-19-P claim. The claim is due within three years or before a sale to a third party, whichever is earlier.
- Using an old cap figure. The $1,000,000 and $1,022,600 caps applied only to earlier transfer periods.
- Planning a sibling buyout without tax advice. A buyout can raise its own property tax questions.
Summary
- Prop 19 applies to parent-child transfers on or after February 16, 2021.
- The home must have been the parent’s principal residence.
- The child must make it a principal residence and file for the homeowners’ exemption within one year.
- For transfers from February 16, 2025 through February 15, 2027, the exclusion covers the factored base-year value plus $1,044,586.
- Market value above the cap is added to the taxable value.
- A home that no child occupies is generally reassessed at market value.
- File BOE-19-P within three years or before a sale to a third party, whichever is earlier.
- The next cap adjustment takes effect February 16, 2027.
