Proposition 19 and Your California Estate Plan
Prop 19 took effect February 16, 2021 and significantly narrowed the property tax exclusion for parent-to-child transfers. Bay Area families with appreciated real estate need to understand what changed.
By Alex Wong, Esq. · Updated July 2026 · Revenue and Taxation Code §63.2
What changed on February 16, 2021
Before Prop 19, Proposition 58 (1986) allowed parents to transfer real property to children without triggering a property tax reassessment — up to $1 million in assessed value for rental, vacation, or commercial property, and a primary residence of any value. Prop 19 replaced this with a significantly narrower exclusion.
| Prop 58 (before 2/16/21) | Prop 19 (from 2/16/21) | |
|---|---|---|
| Primary residence | Full exclusion (any value) | Excluded, but capped if value exceeds AV + $1M |
| Vacation/rental/commercial | Up to $1M assessed value excluded | No exclusion — full reassessment |
| Child must move in? | No | Yes, within one year, as primary residence |
| Transfer limit | Unlimited for primary home | One property per transferee (must be their primary residence) |
How the primary residence exclusion cap works
Under Prop 19, a child who receives a parent's primary residence and moves in as their own primary residence within one year qualifies for a partial exclusion. But the exclusion has a $1 million cap on the "assessed value benefit."
If the current market value (CMV) of the home exceeds the parent's assessed value (AV) by more than $1 million, the new assessed value is:
New AV = CMV − $1,000,000
If the difference between CMV and AV is $1 million or less, no reassessment occurs and the child inherits the parent's low tax base.
Worked examples
Example 1: Full exclusion
No reassessment. Child inherits $250,000 assessed value.
Example 2: Partial reassessment
New AV = $1,800,000 - $1,000,000 = $800,000 (up from $300,000).
Example 3: Full reassessment (child does not move in)
Full reassessment to $2,000,000. Child owes taxes at market value.
Planning implications for Bay Area families
Prop 19 created a significant property tax burden for families intending to pass appreciated real estate to children. Common situations to address in an updated estate plan:
Rental or vacation properties will be fully reassessed
Under Prop 58, a rental property with a $200,000 assessed value and $1.2 million market value could pass to children without reassessment. Under Prop 19, that property is now reassessed to market value — an extra $10,000 to $12,000 per year in property taxes, every year. This changes the calculus of whether to hold, sell during life, or restructure ownership.
Primary residence: the one-year clock matters
If a child who inherits the family home does not move in and establish it as their primary residence within one year, the full reassessment applies regardless of value. Estate plans should account for the realistic likelihood of each beneficiary's ability and willingness to occupy the property.
Income tax vs. property tax trade-off for lifetime gifts
Gifting appreciated property during life avoids Prop 19 reassessment at death but transfers the donor's low income tax basis. If the child sells the property, they owe capital gains tax on all appreciation. In most Peninsula scenarios, the capital gains cost of a lifetime gift exceeds the Prop 19 property tax cost of inheriting at death. A financial analysis is required before choosing this path.
Updating existing trusts
If your trust was drafted before 2021 and includes provisions for passing real property to children, review whether those provisions are still optimal in a Prop 19 world. Some trusts were drafted to maximize use of the old Prop 58 exclusion in ways that no longer serve their original purpose.
Frequently asked questions
Does transferring property to a revocable living trust trigger Prop 19?
No. Transferring your home to a revocable living trust during your lifetime is not a change in ownership under California law (Revenue and Taxation Code section 62(d)). Your property tax base stays the same. Prop 19 only becomes relevant when the property is transferred to children — whether by death through a trust or will, or by inter vivos gift.
What happened to the $1 million exclusion for other property under Prop 58?
It is eliminated for transfers occurring on or after February 16, 2021. Under Prop 58 (the old law), each parent could transfer up to $1 million in assessed value of non-primary-residence property — vacation homes, rentals, commercial property — to children without reassessment. Prop 19 eliminated this category entirely. The only remaining parent-child exclusion applies to a primary residence, subject to the $1 million cap on assessed value benefit.
The home I plan to leave to my child will be reassessed under Prop 19. How much will property taxes increase?
The increase depends on how much the assessed value rises. California property taxes are approximately 1.1 to 1.2 percent of assessed value (base rate plus local assessments). If reassessment adds $800,000 to the assessed value, annual property taxes increase by roughly $8,800 to $9,600. Over 10 years, that is $88,000 to $96,000 in additional taxes on the inheritance alone — before any estate costs.
Can I transfer property to my children now to avoid Prop 19?
Transfers on or after February 16, 2021 are governed by Prop 19. Transfers that were completed before that date — where a deed was recorded before February 16, 2021 — are still governed by Prop 58. Gifting property to children before death to avoid Prop 19 may save on property taxes but can create income tax costs: the recipient takes your low carryover basis instead of the stepped-up basis they would receive at death. The trade-off requires analysis.
What is a stepped-up basis and why does it matter here?
When you inherit property, your income tax basis is "stepped up" to the fair market value on the date of death (IRC section 1014). If you inherited a home worth $1.5 million that the decedent bought for $200,000, you can sell immediately for $1.5 million and owe zero capital gains tax. If the same property was gifted to you during the donor's lifetime, you take the original $200,000 basis and owe capital gains on the full $1.3 million gain when you sell. Gifting to avoid Prop 19 reassessment often triggers much larger income tax on sale.
Does Prop 19 affect the transfer of a family farm?
Yes, but with a separate exclusion. Prop 19 includes a family farm exclusion that allows certain transfers of family farms to children or grandchildren without reassessment, as long as the transferee continues operating it as a family farm. The farm exclusion has its own requirements and should be reviewed with an attorney familiar with agricultural property.
