Prop 19 Parent-Child Exclusion Rules for the Family Home
Updated July 2026. Figures and law current as of this date.
Prop 19 changed everything for California heirs on February 16, 2021. If your parents owned property assessed well below today's market value, you need to know exactly what you can protect and what you cannot: before the title transfers.
Proposition 19 replaced Prop 58's unlimited parent-child property tax exclusion with a narrower rule: the exclusion now applies only to a family home that the heir moves into within 1 year, and only up to a $1,044,586 cap above the parent's assessed value. Rental properties, vacation homes, and investment properties receive no exclusion at all: they are reassessed to full current market value when title transfers.
If your parents bought their Los Angeles County home in 1985 for $120,000 and it's worth $1.2 million today, what happens when you inherit it depends entirely on what you do with it next. That's the core of Prop 19, and it's where heirs in LA lose real money by not knowing the rules in advance.
If you are inheriting a house in California, Prop 19 is only the property tax piece of the puzzle. This guide focuses on the parent-child exclusion rules for the family home; for the broader picture across rentals, farms, and multi-heir situations, see Prop 19 and inherited property in California.
What Prop 58 Allowed vs. What Prop 19 Allows
Since 2013, working with LA County families on probate and inherited property, the single most frequent source of confusion I run into has been heirs who believe the old rules still apply. They don't. Prop 19 passed in November 2020 and took effect February 16, 2021. For anyone inheriting property after that date, the rules changed fundamentally.
Under the old Prop 58, a parent could transfer any property to a child: their primary home, a rental duplex in Boyle Heights, a vacation cabin in Big Bear: and the child would inherit not just the property, but the low assessed value that came with it. No occupancy requirement. No dollar cap. A parent who bought a rental building in 1975 assessed at $80,000 could pass it to a child with a $1,000-per-year property tax bill even though the building was worth $2 million on the current market.
Prop 19 ended that. The comparison below shows exactly what changed.
| Category | Prop 58 (Before Feb 16, 2021) | Prop 19 (Feb 16, 2021 Onward) |
|---|---|---|
| Eligible property types | Any property: primary home, rental, vacation, commercial | Primary residence ONLY |
| Occupancy requirement | None: heir could rent it out immediately | Heir must move in within 1 year |
| Dollar cap | Unlimited: full assessed value carried over | $1,044,586 above parent's assessed value (2025–2027) |
| Rental properties | Full exclusion: inherited at parent's low assessment | No exclusion: fully reassessed to current FMV |
| Vacation homes | Full exclusion | No exclusion: fully reassessed |
| Multiple heirs | All children qualified regardless of occupancy | At least one child must move in; that occupancy preserves the exclusion for the property |
| Homeowners' exemption filing | Not required for exclusion | Required within 1 year: late filing limits the exclusion to prospective relief |
| Grandparent-to-grandchild | Allowed with exclusion under Prop 193 | Allowed only if grandchild's parent is deceased |
What heirs lost under Prop 19 is enormous, especially in Los Angeles. The families I work with who are most impacted are the ones who inherited rental properties in communities like Boyle Heights, Koreatown, or East LA: neighborhoods where parents held on for decades and assessments are tiny relative to today's values. Losing the rental property exclusion isn't a technicality. It's a five-figure annual tax increase that changes whether keeping the property makes financial sense at all.
Parent-Child Exclusion Requirements: Primary Residence Rules
The California Proposition 19 parent-child exclusion has two primary residence requirements, and both must be met: the home must have been the parent's principal residence, and it must become the heir's principal residence within 1 year of the date of death or transfer. The heir also files for the homeowners' exemption within that same 1-year window.
Prop 19 draws a clear line between "family home" and everything else. Understanding which category your inherited property falls into is the first question to answer, because it determines your property tax exposure before you decide what to do next.
For an LA County home assessed at $300,000 that's now worth $910,000, the difference between qualifying and not qualifying for the exclusion is roughly $7,600 per year in additional property taxes: every year, indefinitely. Over 10 years, that's $76,000. The property type classification is not an administrative detail; it's a financial decision.
What Happens to Rental Properties: The Dollar Reality
Here's the scenario I see most often in Los Angeles County probate cases: a parent bought a small rental property: maybe a duplex in Highland Park or a three-bedroom rental in Culver City: in the 1980s or 1990s. They've been holding it for decades, paying property taxes based on an assessed value that hasn't kept pace with the market because of Prop 13's 2% annual cap on increases.
When the heir inherits that property today, Prop 19 forces a full reassessment to current fair market value. Here's what that means in LA County numbers for 2026.
Current FMV at transfer: $910,000 (reassessed tax: ~$11,375/yr at 1.25% effective rate)
Annual property tax increase: $7,625 per year, every year: indefinitely.
Over a 10-year hold, that's $76,250 in additional property taxes on top of everything else. For an heir who planned to keep the rental as a passive income property, this completely changes the investment math. If the rental was generating $3,500/month in rent ($42,000/year gross), adding $7,625/year in extra property tax drops net operating income by more than 18% before even accounting for maintenance, insurance, and management fees.
This is why the sale timing decision is so critical. If heirs are going to sell the property anyway, selling before or during probate rather than taking title and then selling can sometimes reduce the overall tax exposure: though the specifics depend on the estate's situation and you should verify with a probate attorney and CPA.
The reassessment happens when title transfers to the heir's name: not when the parent dies. If probate is moving slowly and the heir is considering options, getting professional advice on transfer timing relative to any planned sale can matter financially. I work regularly with probate attorneys in LA County and can refer you to one if needed.
The Partial Exclusion Formula: Step-by-Step
When the heir qualifies for the Prop 19 exclusion (moving into the primary residence within 1 year), the exclusion is not necessarily "no reassessment." It depends on how far above the parent's assessed value the current market value sits. If the gap exceeds $1,044,586, there is a partial reassessment. Here's how to calculate it.
New Taxable Assessment = FMV at Transfer minus (Parent's Assessed Value plus $1,044,586)
If the result is zero or negative, no reassessment occurs. If positive, that amount is added to the parent's assessed value to calculate the new base assessment.
Example 1: Under the Cap: No Reassessment
Example 2: Above the Cap: Partial Reassessment
The $1,044,586 figure applies from February 16, 2025 through February 15, 2027 (BOE Notice NR 25-02). The State Board of Equalization adjusts it every other year based on the change in the FHFA House Price Index for California, not the CPI. The next adjustment takes effect February 16, 2027: verify the then-current figure with your county assessor or at boe.ca.gov/prop19.
The Proposition 19 $1 Million Exclusion Adjustment: Where It Stands in 2026
The Prop 19 exclusion amount for 2026 is $1,044,586. The State Board of Equalization set that figure in Notice NR 25-02, and it applies to parent-child transfers occurring February 16, 2025 through February 15, 2027. Nothing about the amount changed during 2026: the next adjustment takes effect February 16, 2027.
The mechanics: Prop 19 started with a $1,000,000 exclusion in February 2021 and requires the BOE to adjust it every other year by the percentage change in the Federal Housing Finance Agency's House Price Index for California. Here is the full adjustment history.
| Transfer Period | Exclusion Amount | Change |
|---|---|---|
| Feb 16, 2021 – Feb 15, 2023 | $1,000,000 | Baseline set by Prop 19 |
| Feb 16, 2023 – Feb 15, 2025 | $1,022,600 | +2.26% (BOE biennial adjustment) |
| Feb 16, 2025 – Feb 15, 2027 | $1,044,586 | +2.15% (BOE Notice NR 25-02) |
| From Feb 16, 2027 | Pending | BOE will publish the new amount before it takes effect |
The 2026 Attempts to Amend Prop 19
Efforts to roll back Prop 19's inheritance rules continued into 2026, and none of them changed the law. The Howard Jarvis Taxpayers Association's "Repeal the Death Tax" initiative, which would have restored the old Prop 58 and Prop 193 exclusion rules, did not qualify for the November 2026 ballot: organizers collected roughly 560,000 signatures against the 874,641 required, after earlier attempts in 2022 and 2024 also fell short. HJTA has said it is now aiming at 2028.
In the Legislature, SCA 4 (Seyarto) proposes restoring parent-child transfer protections in the state constitution. As of July 2026 it is pending, not law. Bottom line for heirs: every rule in this guide, including the $1,044,586 cap and the 1-year occupancy requirement, is fully in effect for any transfer that happens in 2026.
Is There a Prop 19 Inheritance Tax in California?
No. California has no inheritance tax and no state estate tax. What people search for as the "Prop 19 inheritance tax" or "death tax" is actually a property tax reassessment: when an inherited property does not qualify for the parent-child exclusion, the county assessor resets its taxable value to current market value, and the annual property tax bill rises with it. On the LA County rental example above, that reassessment works out to roughly $7,625 in additional property tax per year.
Grandparent-to-Grandchild Transfers: The Deceased Parent Rule
California allows grandparents to transfer a family home to a grandchild with the same Prop 19 exclusion: but only if one specific condition is met: the grandchild's parent who is the biological or adopted child of the transferring grandparent must be deceased at the time of the transfer.
This rule exists to prevent the grandparent-to-grandchild transfer from being used as a workaround: essentially "skipping" a generation while the middle-generation parent is still alive. If the grandchild's parent is still living, the grandparent would need to transfer to the parent first (parent-child transfer), and the parent would then need to separately transfer to the grandchild (another parent-child transfer).
Grandparent-to-Grandchild: Decision Tree
One practical nuance I see come up in LA County probate cases: if a grandparent is in poor health and wants to transfer a property to a grandchild while a middle-generation parent is still alive, this path doesn't work under Prop 19. The only route is through the parent: which requires the parent to also eventually transfer it to the grandchild, each step carrying its own Prop 19 analysis.
Filing Requirements: BOE-19-P and BOE-19-G
Qualifying for the Prop 19 exclusion is not automatic. You have to claim it by filing the correct form with your county assessor. File the homeowners' exemption within 1 year of the date of death or transfer to get relief back to that date: per the BOE, an exemption claim filed after the 1-year window means the exclusion applies prospectively from the filing date, not retroactively.
The forms are straightforward, but the deadlines matter. Here's what you need to know for Los Angeles County transfers. For a form-by-form walkthrough, see How to File Proposition 19.
| Form | When to Use | Filing Deadline | Where to File |
|---|---|---|---|
| BOE-19-P | Parent-to-child transfer (or step-parent, child of step-parent) | Within 3 years of transfer date, and before transferring to any third party | Los Angeles County Assessor's Office: assessor.lacounty.gov |
| BOE-19-G | Grandparent-to-grandchild transfer (requires deceased parent verification) | Within 3 years of transfer date, and before any subsequent transfer | Los Angeles County Assessor's Office: assessor.lacounty.gov |
| Homeowners' Exemption | Required in addition to BOE-19-P or BOE-19-G: proves occupancy | Within 1 year of the date of death or transfer (stricter than BOE form deadline) | Same county assessor |
There are two separate filing clocks, and for an inheritance both run from the date of death. The homeowners' exemption must be filed within 1 year: that's the tighter deadline. The BOE-19-P or BOE-19-G forms have a 3-year window, but you still must file the BOE form before you sell or transfer the property to anyone else. If you sell in year 2 without having filed the BOE form, you lose the exclusion permanently for that transfer.
One timing issue that trips up heirs in probate situations: for an inheritance, the date of transfer for reassessment purposes is the date of death, not the date the court orders distribution. The BOE's deadlines run from the date of death or transfer, so in a 12-to-18-month LA County probate, much of the 1-year homeowners' exemption window can be gone before the heir even has keys. Plan the occupancy decision early in the probate, not at the end.
For heirs going through a trust administration, the clock is the same: it runs from the date of death or transfer. Trusts simply move faster: the trustee can deed the property within weeks instead of months, which leaves more of the 1-year window available for the move-in and the homeowners' exemption filing.
Strategies for Heirs: Sell, Move In, or Plan Around the Cap
After more than a decade of working with LA County families through inheritance situations, the clearest advice I can give is this: the decision about what to do with an inherited property should happen before title transfers, not after. Once the title is in your name, your options narrow. The tax events have already started.
Here are the six most common heir scenarios I see in Los Angeles County and the best move for each.
One planning note for parents still holding inherited property in their own estates: if you hold the family home in a revocable living trust, the title transfers to your heirs almost immediately upon death: no probate wait. That gives heirs more time and flexibility to make the occupancy decision and file the required forms within the 1-year window. It also means the 1-year clock isn't cut short by a 12-to-18-month probate. This is one reason trust planning remains valuable in California even with Prop 19 in effect.
Prop 19 Inheritance: Situation to Outcome Guide
| Your Situation | Prop 19 Outcome | Key Deadline |
|---|---|---|
| Parent's home inherited; you plan to move in within 1 year | Exclusion available: up to $1,044,586 cap above parent's assessed value | File homeowners' exemption within 1 year; BOE-19-P within 3 years |
| Parent's home inherited; you plan to rent it out | Full reassessment to current FMV: no exclusion | Reassessment occurs at title transfer |
| Inherited home FMV is under parent's assessed value + $1,044,586 | No reassessment if you move in: keep parent's low assessment | Occupy within 1 year; file homeowners' exemption |
| Inherited home FMV exceeds parent's assessed value + $1,044,586 | Partial reassessment: only the excess above the cap is added to parent's assessed value | Same as above; run the formula to know your new assessment |
| Inherited vacation home or second home | Full reassessment to current FMV: no exclusion regardless of occupancy | Reassessment occurs at transfer |
| Grandparent transfers to grandchild; grandchild's parent is deceased | Exclusion available: same rules as parent-child; file BOE-19-G | Occupy within 1 year; file homeowners' exemption within 1 year |
| Grandparent transfers to grandchild; grandchild's parent is alive | No exclusion available: full reassessment | N/A: consider two-step parent-then-child transfers instead |
| Transfer occurred before February 16, 2021 | Prop 58 applies: unlimited exclusion, no occupancy requirement, no cap | File BOE-58-AH; 3-year deadline from transfer date |
| Inherited a family farm | Special farm exclusion: does not need to be primary residence; must continue as farm | File with county assessor; confirm eligibility under Prop 19 farm rules |
| Inherited a rental property and want to sell | Full reassessment at transfer; sell after transfer triggers step-up in basis capital gains rules: consult CPA | Consider selling timing relative to transfer date for optimal tax outcome |
Frequently Asked Questions About the Prop 19 Parent-Child Exclusion
Straightforward answers to the questions I hear most from LA County heirs dealing with Prop 19.
What is the Prop 19 parent-child exclusion?
The Prop 19 parent-child exclusion lets a child inherit a parent's principal residence without full property tax reassessment. The home must become the child's principal residence within 1 year, and the exclusion covers up to $1,044,586 above the parent's taxable value. Claim it by filing form BOE-19-P with the county assessor.
What changed under Proposition 19 for inherited property in California?
Before February 16, 2021, Prop 58 let parents transfer any property to children with no property tax reassessment and no occupancy requirement. After Prop 19 took effect, the exclusion is limited to a primary residence only: the heir must move in within 1 year and file for the homeowners' exemption. Rental properties, vacation homes, and investment properties no longer qualify for any exclusion and are reassessed to current market value.
How much is the Prop 19 exclusion in 2026?
The Prop 19 exclusion is $1,044,586 for transfers occurring February 16, 2025 through February 15, 2027, per BOE Notice NR 25-02. The Board of Equalization adjusts the original $1 million amount every other year based on the change in the FHFA House Price Index for California. The next adjustment takes effect February 16, 2027.
How do I calculate the partial exclusion under Prop 19?
The partial exclusion formula is: Taxable New Assessment = FMV at Transfer minus (Parent's Assessed Value plus $1,044,586 cap). For example, if the parent's assessed value was $300,000 and the home's FMV at transfer is $1,500,000, the calculation is $1,500,000 minus ($300,000 plus $1,044,586) = $155,414 of the FMV is reassessed. If FMV minus assessed value is less than or equal to the cap, the heir pays no additional property tax.
Do I have to live in an inherited house to keep the tax base under Prop 19?
Yes. To keep the parent's low tax base, at least one heir must make the inherited house their principal residence within 1 year of the date of death or transfer and file for the homeowners' exemption. If no heir moves in, the property is reassessed to full market value, no matter how long the parent owned it.
What is the deadline to move into an inherited home under Prop 19?
The heir must establish the inherited home as their principal residence within 1 year of the date of death or transfer and file for the homeowners' exemption in that same window. Per the BOE, an exemption claim filed after the 1-year period does not void the exclusion entirely: it is applied prospectively from the filing date rather than back to the transfer date.
Can I inherit a rental property in California without property tax reassessment under Prop 19?
No. Under Prop 19 (effective February 16, 2021), rental properties, vacation homes, and investment properties do not qualify for any parent-child transfer exclusion. The property is fully reassessed to its current fair market value when title transfers to the heir. If an LA County rental was assessed at $300,000 but worth $910,000 today, annual property tax will jump from roughly $3,750 to $11,375 per year: an increase of over $7,600 annually.
Can a grandparent transfer a home to a grandchild under Prop 19?
Yes, but only if the grandchild's parent who is the child of the transferring grandparent is deceased at the time of transfer. The same principal residence and 1-year occupancy rules apply. If the grandchild's parent is still alive, the grandparent-to-grandchild transfer does not qualify for the Prop 19 exclusion. File BOE-19-G with your county assessor.
What forms do I need to file for the Prop 19 parent-child transfer exclusion?
For a parent-to-child transfer, file BOE-19-P (Claim for Reassessment Exclusion for Transfer Between Parent and Child Occurring on or After February 16, 2021) with your county assessor within 3 years of the transfer date, and before transferring the property to any third party. For grandparent-to-grandchild transfers, the form is BOE-19-G.
Is there a Prop 19 inheritance tax in California?
No. California has no inheritance tax and no state estate tax. What people call the Prop 19 inheritance tax is a property tax reassessment: when an inherited property does not qualify for the parent-child exclusion, its taxable value resets to market value and the annual property tax bill rises, often by thousands of dollars per year.
