Your parents bought that house in Pasadena in 1978. The property taxes reflect a world that no longer exists. Their assessed value might be $180,000 on a home worth well over a million dollars today. You have always assumed that low tax base would pass down to you when the time came. Prop 19 changed that assumption, and most California families do not find out until they are already sitting at a kitchen table sorting through paperwork and grieving.
Proposition 19 passed in November 2020 and took effect February 16, 2021. What it did to inherited property inside a trust, how the exclusions work, and what happens when they do not is something every California homeowner with kids needs to understand now, before the estate attorney gets involved, not after the funeral.
How Prop 19 Changed Inherited Property Tax Rules in California
A parent in Marin County paying $2,400 a year in property taxes could easily have a child suddenly facing $18,000 annually on the same house. That gap is Prop 19 in action.
California voters approved Proposition 19 in November 2020, and by 2025 the impacts were well documented across California counties, estate planning offices, and family discussions about inherited property. The change ended the old Proposition 58 and 193 rules, which let parents pass almost any property to their children at the original, protected tax base under Proposition 13. Rental homes, vacation cabins in Lake Tahoe, commercial investments, and the family home all passed down with their low assessments intact. That era is over.
Your children can no longer automatically inherit your low property tax base. What remains is a narrow exclusion with strict conditions, and missing any one of them triggers a full reassessment.
Not long ago, I worked with a young couple in Glendora who were trying to decide what to do after inheriting a parent’s bungalow. They had listed it twice with two different agents and watched six months pass with zero offers. Budgeting updates for the house was hard when the property tax bill had already tripled after the transfer. They eventually sold it directly and moved on. The tax reassessment had not waited for them to figure things out.
For many California families, this represented the most significant change to property tax law since Proposition 13 passed in 1978. The confusion costs families real money. In June 2026, California homes were selling for a median price of $777,566, up 2.0 percent year over year. At those levels, a reassessment from a decades-old base to current market value can push annual property taxes from a few thousand dollars to tens of thousands. Without a plan, the home becomes unaffordable to keep.
What Is the Parent-Child Exclusion Under Prop 19?
Sit across from a seller who just lost a parent and you hear the same thing constantly: “The house is in a trust, so we are protected, right?” The trust is half the answer. It is what you do with the property after the transfer that determines whether the exclusion holds.
Current law has narrowed parent-child transfer exclusions so that inherited homes are typically reassessed to their current market value unless the child moves in and files correctly within one year. The exclusion exists, but it comes with a strict list of requirements that have to be met in a specific order, and skipping even one step disqualifies the whole thing.
First, the inherited property must have been the parent’s primary residence at the time of transfer. A rental in Long Beach or a vacation cabin near Big Bear does not qualify, even if it has been in the family for decades. Second, the child who inherits must move into that home and establish it as their own primary residence. Third, they must file the correct claim form with their county assessor.
As of February 16, 2025, the reassessment exclusion amount under Proposition 19 for intergenerational transfers has been adjusted to $1,044,586, applying to transfers occurring between February 16, 2025 and February 15, 2027. That figure, confirmed by the California Board of Equalization, means the exclusion is not unlimited even when all conditions are met. The cap trips up a lot of heirs.
Say a parent’s home was assessed at $250,000 under Prop 13, and it is now worth $1,100,000. A gap of $850,000 falls under the current exclusion threshold. Within a year, the child moves in, files the claim, and the assessed value stays near what the parent was paying. But push that home’s value to $1,600,000 and the child who moves in still faces a partial reassessment on the difference above the cap.
When multiple siblings inherit the same property, things get messier. Only the heir who actually moves in gets the benefit. If you have three siblings and only one moves in, the rest of the property gets reassessed to market value regardless of what the trust says.
What the Grandparent-to-Grandchild Exclusion Allows
Grandparents sometimes put a house in a trust intending to skip a generation entirely and leave it directly to grandchildren. The logic seems sound: skip the middle step, simplify the estate, protect the kids. Prop 19 built a gate that blocks most of those transfers.
A separate grandparent-to-grandchild exclusion exists under Prop 19, but it only applies if both of the grandchild’s parents are deceased. If either parent is living, the transfer is not eligible. That single condition eliminates the vast majority of grandparent-to-grandchild transfers families are hoping to make.
For grandparent-to-grandchild transfers, the claim form is BOE-19-G. Filing that form with your county assessor is required to claim the exclusion. But before the paperwork matters, the eligibility question has to be answered, and most families learn their situation will not qualify only after they are already at the assessor’s counter.
If the grandchild will not occupy the property as a primary residence, it is reassessed to current fair market value even if the deceased-parent requirement is met. A grandchild who inherits grandma’s Tarzana home but wants to keep it as a rental gets no protection at all.
How Inherited Property Inside a Trust Is Affected by Prop 19
This is the part most people get wrong, because holding property in a trust sounds like protection against reassessment. Trusts and Prop 19 exclusions are two completely separate issues, and conflating them is an expensive mistake.
A revocable living trust is treated as the grantor’s property during their lifetime. However, when the parent dies and the property passes to a child through the trust, that is a change in ownership for Prop 19 purposes. The same rules apply: the property must have been the parent’s primary residence, the child must move in within one year, and the BOE-19-P must be filed.
Creating a trust does not create a Prop 19 exclusion. What it does is avoid probate, which matters enormously in California where probate can drag on for a year or longer and attorneys’ fees are set by statute based on the estate’s gross value. But avoiding probate and preserving a low property tax base are two different goals that require two different strategies. If the property was never actually retitled into the trust, that is a separate problem with its own fix, and we cover it in our guide to the Heggstad petition.
In cases of trusts, the change in ownership date is the date the trust became irrevocable. For a revocable living trust, that date is typically the date the grantor dies. For an irrevocable trust set up while the parents were alive, the clock may have started running much earlier than the family realizes, which means the one-year window to file could already be closed before anyone contacts an assessor.
Irrevocable trusts involve a more complex analysis and can trigger a change in ownership at different points depending on how they are structured. An irrevocable trust that holds the family home in Arcadia might have already triggered a reassessment event years before anyone died. A conversation with an attorney who specializes in California property tax law is worth having before assuming the trust handles everything.

What Happens to Property Taxes When the Exclusion Does Not Apply
Some sellers push back on this: “Our parents owned the house for forty years, so the assessed value cannot be that far off from market.” In California, it can be, and usually is.
California’s base property tax rate under Proposition 13 is 1 percent of assessed value, plus local voter-approved bonds and assessments that vary by county. A home reassessed from $200,000 to $900,000 carries a tax jump that can run well into five figures annually before local add-ons. Families who planned to keep the property and rent it out sometimes discover the rental income does not come close to covering the new tax bill, so the house gets sold anyway.
For heirs who do not move in, the full reassessment to fair market value often forces the sale of long-held family wealth. This is particularly acute in markets like the San Fernando Valley, the East Bay, and coastal Orange County, where a home bought in the 1980s for $150,000 might appraise today at $1.2 million or more. The math on keeping it simply does not work for heirs who are already carrying their own mortgage somewhere else.
A lot of inherited properties end up sold, and there is no shame in that. If your share of the property taxes after reassessment would cost more than the rent you would collect, liquidating the asset and distributing the proceeds to the beneficiaries is reasonable arithmetic. We buy inherited homes across the Central Valley, whether that means cash home buyers in Fresno or a company that buys homes in Bakersfield.
When siblings co-own and cannot agree, the property can end up in a partition action, which is a court proceeding that forces a sale. That is the worst-case outcome for everyone: legal fees, delays, and family relationships damaged. Getting ahead of the decision before emotions are fully running the show saves money and relationships.
How to Apply for the Parent-Child Exclusion After Prop 19
A successor trustee in Rancho Cucamonga called me on a Wednesday, three weeks after her mother passed. Her house was in a revocable living trust, and she had no idea there was a filing deadline attached to her ability to keep the low property tax base. That call happens constantly.
For a parent-to-child transfer, file BOE-19-P with your county assessor within three years of the transfer date, and before transferring the property to any third party. That three-year window sounds generous until you factor in probate delays, family disagreements, and the time it takes for an heir to actually move in and establish occupancy.
The filing process works like this: get the BOE-19-P from your county assessor’s website, complete it, and submit it along with documentation proving occupancy and the parent-child relationship. The assessor reviews the claim and determines whether the exclusion applies. If the home’s market value exceeds the parent’s base year value by more than the current inflation-adjusted cap, the assessor calculates the partial reassessment.
Missing a filing deadline or misunderstanding occupancy requirements can lock in a much higher annual property tax bill. The one-year occupancy window and the three-year filing window run concurrently, so there is no benefit to waiting. Moving into the home and filing the claim as quickly as possible after the deed records is the right move, and I have seen closings where a few weeks of delay turned a straightforward transfer into a scramble at the assessor’s office.
One pattern I keep seeing: adult children who inherit with siblings sometimes delay the occupancy decision because they are trying to reach a consensus that never comes. Meanwhile the clock runs. Whoever is going to move in needs to do it, file the claim, and sort out the co-ownership arrangement separately.
What the Base Year Value Transfer Rule Means for Seniors
The parent-child exclusion gets most of the attention, but Prop 19’s gift to aging homeowners who want to move is underappreciated and underused.
Effective April 1, 2021, Proposition 19 allows any person who is at least 55 years of age, any severely disabled person, or any victim of a wildfire or natural disaster to transfer the base year value from their original principal residence to a replacement property anywhere in California. Before Prop 19, that portability was limited to same-county moves or counties that had opted into a reciprocity agreement, which was a short list. A retiree in Ventura County who wanted to downsize to San Diego County was often stuck, because crossing county lines meant losing decades of accumulated tax savings.
Homeowners who are 55 or older or severely disabled can transfer their base year value up to three times under Prop 19, per the State Board of Equalization, and that is a per-person limit regardless of whether you used a transfer under the old Prop 60/90 rules before April 1, 2021.
A senior in Thousand Oaks who bought in 1991 can now sell, take their base year value with them, and buy a smaller home in Palm Springs, Sacramento, or anywhere else in the state without starting over on the tax clock. That flexibility changes the calculus on whether it is worth selling a large family home or sitting in it indefinitely to protect the low tax rate.
One of the biggest improvements from the old rules is the new policy on replacement home value. Prop 19 allows the transfer even when the replacement home costs more, though the amount over the original home’s sale price does get added to the transferred base year value.
How Prop 19 Affects Your Estate Plan in California
At a statewide median of $777,566 as of June 2026, a typical family home inherited in almost any California city carries enough market value to create a real Prop 19 reckoning without active planning.
Most estate plans built before 2021 were designed under the old Proposition 58 rules. They assumed children could inherit any parcel of real estate, at any value, and keep the Prop 13 base indefinitely. That assumption is now wrong, and attorneys are finding that a large share of existing trusts have not been updated to reflect current law.
A properly structured living trust includes Prop 19 compliance language to help your children claim the exclusion. That means the trust document should specify which property is the grantor’s primary residence, include instructions for the successor trustee on filing the BOE-19-P promptly, and address what happens if the beneficiary cannot or will not occupy the home within the one-year window.
Prop 19 does not change whether you need a living trust. What it changes is what you need your living trust to accomplish. Probate avoidance remains a powerful reason to use one. But the trust document alone does not preserve the property tax base; that work has to happen through the child’s occupancy and a timely filing.
An heir in Pomona who inherited a property packed with thirty years of belongings found this out the hard way when she opened the garage and realized her siblings in Nevada and Texas had no interest in sorting anything. They wanted the sale, and they wanted it fast. She was willing to move in to keep the low tax base, but three siblings each owning a share made that decision legally complicated. They eventually sold directly for cash, split the proceeds, and the transaction closed before the family dynamics could splinter further.
If you are rethinking your California estate plan in light of Prop 19, knowing what the property is worth today and what your heirs would face in a sale scenario is a useful starting point for any estate attorney conversation.

There is currently a third attempt underway to repeal the inheritance portions of Prop 19. The initiative, titled “Fix Prop 19 to Save Our Children’s Future,” began circulating petitions in late 2025. If proponents gather enough valid signatures by the May 2026 deadline, it could appear on the November 2026 ballot. Plan under the current rules. Counting on a repeal is a bet most families cannot afford to lose.
Frequently Asked Questions
Is There a Way to Work Around Prop 19?
There is no shortcut that eliminates the reassessment rules, but there are legitimate planning strategies that reduce the impact. Gifting property during the parent’s lifetime may lock in a lower assessed value depending on when the transfer happens and how it is structured, though that approach involves its own tax considerations an attorney should review carefully. Placing a property into a life estate or using certain trust structures might also affect when the change in ownership occurs. Your best path is talking with a California estate planning attorney before a transfer happens, not after.
Is It Harder to Sell a House That Is in a Trust?
Not necessarily, though the process involves a few extra steps. The successor trustee has authority to sign documents on behalf of the trust, so there is no need for probate court involvement. Buyers and title companies are generally comfortable with trust sales. If anything, a property held in a trust often sells faster than one going through probate because the successor trustee can act without court approval, keeping the timeline cleaner.
Do You Have to Pay Taxes on Property Inherited Through a Trust?
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. If you sell the inherited property, you may also face federal capital gains tax on any appreciation above your stepped-up cost basis at the date of death, which is a separate issue from property taxes entirely.
What Happens When You Inherit Property Through a Trust?
In cases of trusts, the change in ownership date is the date the trust became irrevocable. For most revocable living trusts, that is the date the grantor passes away. At that point, the county assessor can reassess the property unless an exclusion applies. The successor trustee’s job is to transfer the deed to the beneficiary, notify the county assessor of the change in ownership, and file the appropriate exclusion claim as quickly as possible. The beneficiary who intends to live in the home should establish occupancy and file for the homeowners’ exemption to support their claim. You can check out other frequent questions if you are still working through the options.
