You bought the fourplex decades ago, the assessment never caught up to the market, and the tax bill is a fraction of what a buyer today would pay. The plan was always that the kids would take it over and keep that bill. In California, that plan changed. Proposition 19, effective in 2021, narrowed the parent-to-child property tax exclusion so far that, for most investment property, it no longer applies.
This article is about California law specifically. Prop 19 and Prop 13 are California ballot measures with no equivalent in most states. Other states assess property on their own schedules, and some reassess annually regardless of who owns the property. Jason Gaudy, an estate planning and probate attorney at Gaudy Law in Upland, California, works with these rules every week.
What did Prop 19 actually change?
Gaudy’s summary of the old rule is short. If a parent specifically designated a property to one of their children, that child could maintain the parent’s property tax basis: the assessed value the tax bill is calculated from, not the market value.
Now, he says, that ability is essentially limited to a primary residence.
Read that as an investor and the consequence is obvious. When the rental house, the duplex, the strip center, or the parcel you’ve held since the Clinton administration passes to a child, the assessment resets. The new bill is based on current value.
“Prop 19 really hit hard for people with investment properties,” Gaudy says.
Why the old assessment matters more than people expect
Prop 13, passed in 1978, is the reason California assessments drift so far below market. It caps how fast the assessed value of a property can rise while the same owner holds it. Hold something for thirty years in an appreciating market and the gap between what it’s assessed at and what it’s worth becomes enormous.
Gaudy gives a live example from his practice. He had been talking that same day with a client paying roughly a thousand dollars a year in property taxes on a property worth somewhere around $800,000. His reaction was that the number had to be Prop 13. Nothing else explains it. That family had to transfer part of the property, and he had to tell them the assessment was going up on the transferred share, which in that case was about two-thirds of it.
That is the mechanic families miss. Reassessment isn’t a penalty for doing something wrong. It’s the automatic consequence of the property changing hands outside the narrow exclusion that survives.
Is there a way around it?
Gaudy is blunt that there isn’t a clean one. He says there’s not a great way to get around it, and he repeats the point rather than softening it.
His read on why is political rather than technical. In his view, California is looking for tax revenue anywhere it can find it, and there are people who would like to see Prop 13 eliminated entirely. Prop 19, to him, was a way of chipping at the edges of it.
What he does still recommend is planning that minimizes taxes where taxes can be minimized, which is a different thing from making a reassessment disappear. A living trust, for instance, keeps the property out of probate and out of the year-long probate timeline and its costs. It does not preserve a Prop 13 assessment on a rental. Those are two separate problems, and conflating them is how families end up surprised.
The choice this leaves families
Gaudy describes the conversation he has to have as genuinely unpleasant. “It’s depressing sometimes when I have to give people this news,” he says.
The choice he lays out for heirs is narrow. Keep the property and pay higher taxes you may not be able to afford, or sell it, take the money, and try to buy something in a market where everything is expensive. When a property that hasn’t been reassessed in thirty years is suddenly reassessed, he says, the new carrying cost can put it out of reach of the people who inherited it.
That is worth knowing while the owner is still alive, because the owner is the one with options. The heirs mostly don’t have any.
What this means if you’re planning a 1031 exchange
Keep the two taxes separate in your head. A 1031 exchange defers capital gains tax on a sale; it does not carry a Prop 13 assessment forward to replacement property, and it does nothing about the reassessment your children will face on an inherited rental. They’re different taxes under different rules.
Where the connection is real is in the decision itself. If the honest math is that your kids will sell the building the year they inherit it because the new tax bill doesn’t pencil, the owner may prefer to control that disposition personally rather than leave it to a probate court and a reluctant heir. That’s the point at which owners start looking at what a Delaware Statutory Trust is and running numbers with a 1031 exchange calculator. Gaudy’s consistent advice is to have that conversation with your CPA, your advisor, and your estate attorney together, before anything is signed.
