For a family home transferred to a child under the adjustment that runs into early 2027, California’s Proposition 19 lets the child keep the parent’s taxable value only up to the old value plus $1,044,586, according to the State Board of Equalization. That one figure explains why Prop 19 property tax questions come up so often in Porterville and across Tulare County: the rule can save some families a great deal and leave others with a much higher bill than they expected.
Prop 19 affects two very different situations. One is a homeowner aged 55 or older, severely disabled, or displaced by a disaster who sells and buys again. The other is a parent or grandparent passing a home or a family farm to the next generation. This guide covers both, in plain terms, with the caution that tax rules are applied case by case. Confirm your own numbers with a tax advisor, an attorney and the Tulare County Assessor before you rely on them.
Key takeaways
- Proposition 19 took effect in 2021 and replaced the older Prop 58, 60 and 90 rules for most transfers.
- Eligible owners 55 and older can carry their taxable value to a replacement home anywhere in California, up to three times.
- The replacement home must be bought or built within two years of selling the original home.
- A child who inherits a parent’s home keeps the parent’s taxable value only if the child moves in as a principal residence.
- The parent-child exclusion is capped at the old taxable value plus an inflation-adjusted amount, currently $1,044,586.
- Family farms qualify for the parent-child exclusion without the move-in requirement that applies to homes.
How does California property tax work before Prop 19 enters the picture?
California property tax is based on a base year value, not on what a home is worth today. The Board of Equalization explains that Proposition 13 limited the tax rate to 1 percent plus voter-approved bonded debt and, in most cases, limited increases to 2 percent per year. The base year value is set when a property changes ownership or is newly built.
That is why two similar houses on the same Porterville street can carry very different tax bills. The owner who bought decades ago has a low, slowly rising base, while a recent buyer is assessed close to the price they paid. When the older owner sells or passes the house on, the low base normally disappears and the property is reassessed at current market value. Prop 19 decides when some of that low base can survive the change.
Who can transfer a base year value to a replacement home?
Three groups of homeowners can move their taxable value from one principal residence to another under Prop 19: people 55 or older, people who are severely and permanently disabled, and victims of a wildfire or a governor-declared disaster. According to the Board of Equalization’s Prop 19 page, the replacement home can be anywhere in California, and an eligible owner can use the transfer up to three times.
This is a real change from the old rules. Under the earlier system, moving from Tulare County to many other counties meant losing the low base entirely. Now an owner selling a long-held home in Porterville can buy in Visalia, Fresno or the coast and still carry the base, as long as the other conditions are met.
What are the timing and value rules for a replacement home?
The replacement home must be purchased or newly built within two years of selling the original, before or after the sale. The value test then decides whether the old base transfers cleanly or gets adjusted upward.
| When the replacement is bought | Replacement value that still counts as “equal or lesser” |
|---|---|
| Before the original home sells | Up to 100% of the original home’s market value |
| Within the first year after the sale | Up to 105% of the original home’s market value |
| Within the second year after the sale | Up to 110% of the original home’s market value |
If the replacement costs more than the applicable limit, the difference is added to the transferred base year value. A buyer moving from a modest Porterville home to a pricier one can still benefit, but the bill will be higher than the old one. The claim is filed with the assessor in the county where the replacement home sits, after both transactions close and you live in the new home, generally within three years of the purchase.
What happens to property tax when a child inherits a home?
When a parent transfers a family home to a child, the child can keep the parent’s taxable value only if the home was the parent’s principal residence and becomes the child’s principal residence. The BOE says the child must file for the homeowners’ exemption within one year of the transfer to receive the exclusion from that date, and the exclusion lasts only while an eligible child lives there.
A child who inherits a Porterville house and plans to rent it out, sell it, or leave it vacant generally does not qualify. In that case the home is reassessed at market value as of the transfer. Many heirs only learn this when the supplemental tax bill arrives, which is why the decision to move in or not deserves attention early.
Grandparent-to-grandchild transfers follow the same rules, with one more condition: the grandchild’s parent who is the grandparent’s child must have passed away by the date of the transfer.
How does the $1 million cap work?
The parent-child exclusion covers the parent’s factored base year value plus an adjusted amount that started at $1 million and is currently $1,044,586. If the home’s market value at transfer is at or below that total, the child keeps the parent’s taxable value. If it is above, the excess is added to the old value.
A purely hypothetical example shows the mechanics. Suppose a parent’s factored base year value is $150,000 and the home is worth $400,000 at transfer. The limit is $150,000 plus $1,044,586, so the home is well under it and the child keeps the $150,000 base. A property worth well above the limit, such as a large home on acreage, would see the amount over the limit added to the base.
Does Prop 19 treat family farms differently?
Family farms can use the parent-child exclusion too, and the BOE notes that a farm claim does not require a homeowners’ exemption filing, since nobody has to live on farmland. That matters in Tulare County, where many families hold orchards, row crops or grazing land around towns like Terra Bella, Ducor and Strathmore.
The claim forms are the same as for a family home: BOE-19-P for parent to child and BOE-19-G for grandparent to grandchild. The BOE says the claim must be filed within three years of the transfer or before the property is transferred to a third party, whichever comes first. Farm transfers often involve trusts, partnerships or multiple heirs, so this is an area where an attorney and a tax advisor should be involved from the start.
What to Settle Before You Buy, Sell or Accept a Transfer
The deciding factor in almost every Prop 19 case is timing. For a 55-plus owner, the two-year window and the 100, 105 and 110 percent value steps should shape when you list and how much you spend on the next home, so set your replacement budget before you shop. For an heir, the question is whether you will truly live in the home; if not, plan for a reassessed bill and compare holding, renting or selling with that number in hand. In both cases, get the filing deadlines from the Tulare County Assessor and the tax effect from a professional before you sign anything.
