The Short Version
Farmland can still pass from parent to child without a full property tax reassessment. The Prop 19 family farm exclusion applies separately to each legal parcel: a parcel keeps its existing taxable value if its market value does not exceed that taxable value plus $1,044,586 (the amount for transfers through February 15, 2027), and only the excess is added if it does. Nobody has to live on the land. But ground held inside an LLC or partnership does not qualify, and the claim form has a deadline.

On February 16, 2021, Proposition 19 replaced California's old parent-child transfer rules with something narrower. Under the prior law, a principal residence of any value plus up to $1 million of assessed value per parent in other property could pass to children with no reassessment, and the children could do whatever they wanted with it. Prop 19 ended that. What most families in our practice have not heard is that the replacement law, Revenue and Taxation Code section 63.2, treats a family farm differently from everything else, and the differences matter.
What counts as a family farm
The statute defines a family farm as any real property that is under cultivation or being used for pasture or grazing, or that is used to produce an agricultural commodity. That is the whole test. There is no acreage minimum, no income requirement, and no requirement that a house sit on the property. A forty of almonds, a quarter section of row crops, and unimproved rangeland running cattle all qualify on their face.
Two features separate the farm exclusion from the family home exclusion that gets all the press:
-
1
No one has to live there. The family home exclusion requires the child to move in within a year and claim the homeowners' exemption. The family farm exclusion has no residency requirement at all, per the Board of Equalization's guidance to county assessors (Letter to Assessors 2022/012). The land does need to continue as the transferee's family farm, meaning it stays in agricultural use.

The exclusion applies parcel by parcel. Section 63.2 states that the exclusion "shall apply separately to the transfer of each legal parcel that makes up a family farm," and that each parcel is deemed to be its own family farm. For an operation spread across multiple assessor's parcels, this multiplies the protection.
The per-parcel value cap, with numbers
Each parcel keeps its existing factored base year value, the Prop 13 taxable value that may still reflect a purchase decades ago, if the parcel's fair market value at transfer does not exceed that taxable value plus the adjustment amount. The adjustment is $1,044,586 for transfers occurring between February 16, 2025 and February 15, 2027. The Board of Equalization recalculates it every two years against a housing price index; the prior figure was $1,022,600, and the next adjustment lands February 16, 2027.
When a parcel's market value exceeds the cap, the result is a partial adjustment rather than a full reassessment: the amount over the cap is added to the existing taxable value. A hypothetical to make it concrete:
A parcel carries a taxable value of $250,000 and a market value of $1,600,000 at transfer. The cap is $250,000 plus $1,044,586, or $1,294,586. Market value exceeds the cap by $305,414, so the new taxable value is $250,000 plus $305,414, roughly $555,000. Not the old value, but far from a $1.6 million reassessment.
Now multiply that logic across an operation held as four or five separate legal parcels, each with its own cap, and the difference between a planned transfer and an accidental one becomes real money every year, forever. The figures above are illustrative only; actual values are determined by the county assessor.
The parcel with the house on it
One carve-out: a legal parcel that contains a family home is not automatically deemed a family farm. That parcel can instead qualify under the family home rules, which have their own cap and do carry the residency requirement: the home must have been the transferor's principal residence, a child must make it their own principal residence within one year, and the homeowners' or disabled veterans' exemption must be claimed within that year. Families with a homestead on one corner of the ranch effectively run two exclusions side by side, one for the home parcel and one for the farm parcels, each with its own conditions.
Where farm transfers go wrong
Section 63.2 covers transfers of real property between parents and children as people. Transferring membership interests in the LLC that owns the ground is a transfer of entity interests, not of the land, and it does not qualify for the exclusion. Many farm families moved land into LLCs or partnerships for good liability and succession reasons; under Prop 19 that structure and this exclusion pull in opposite directions, and the right answer is a decision for the family's estate attorney, made before a transfer, not discovered after one.
The exclusion is claimed, not automatic. Form BOE-19-P (parent-child) or BOE-19-G (grandparent-grandchild, available only where the grandchild's parents are deceased) goes to the county assessor within three years of the transfer, or before the property passes to a third party, whichever is earlier. A late claim can still get relief, but only from the filing date forward; the escaped years stay reassessed.
The property has to continue as the transferee's family farm. Ground that comes out of agricultural use after the transfer invites the assessor to revisit the exclusion. A family planning to fallow, develop, or convert ground should surface that plan with their attorney and the assessor's office before relying on the exclusion.
What Prop 19 does not decide
Prop 19 is a property tax rule. It says nothing about the income tax side of a transfer, and the two systems regularly point in different directions. Land that passes at death generally receives a stepped-up income tax basis, a separate and often larger financial event than the property tax outcome; we walk through that in Stepped-Up Basis on Inherited Farmland. A lifetime gift of the deed, by contrast, can qualify for the Prop 19 exclusion and still hand the child the parents' original cost basis, trading a property tax win for an income tax problem. Williamson Act contracts, water allocations under SGMA, and estate tax exposure are all decided under their own rules as well.
That is the real lesson we would offer from transition work in Kings, Tulare, and Fresno counties: no single rule decides whether the next generation should receive the land, and optimizing one tax in isolation is how families end up surprised by another. The property tax answer belongs inside the larger keep-or-sell analysis, next to the questions we raise in Keeping the Farm and The Cost of Waiting.

Common Questions
Prop 19 and Farmland:
What Families Ask
Does my child have to live on the farm?
No. Unlike the family home exclusion, the family farm exclusion has no principal residence requirement; nobody has to move onto the property. The land does have to continue as the transferee's family farm, meaning it stays under cultivation or in use for pasture, grazing, or production of an agricultural commodity.
How much value does the exclusion protect?
It applies separately to each legal parcel. A parcel keeps its taxable value if its market value at transfer does not exceed that taxable value plus $1,044,586 (for transfers between February 16, 2025 and February 15, 2027). Above the cap, only the excess is added to the taxable value. The Board of Equalization adjusts the base amount every two years; the next adjustment takes effect February 16, 2027.
Does land held in an LLC or partnership qualify?
No. The exclusion covers transfers of real property between parents and children as individuals. Transferring interests in an entity that owns the land is not a parent-child transfer of the real property and does not qualify. Whether and when to hold ground inside an entity is a question for the family's estate attorney, ideally answered well before any transfer.
What form do we file, and when?
Form BOE-19-P for parent-child transfers, or BOE-19-G for grandparent-grandchild transfers where the grandchild's parents are deceased, filed with the county assessor within three years of the transfer or before the property passes to a third party, whichever is earlier. Late claims receive only prospective relief, so the years in between can be lost.
Does Prop 19 change the capital gains tax?
No. Prop 19 is property tax only. Income tax follows separate federal and state rules, including the stepped-up basis inherited farmland generally receives at death. The two systems are decided independently, which is exactly why a transfer plan should look at both before anything is signed. See Stepped-Up Basis on Inherited Farmland.
