Proposition 19:
Before vs. After
for Inherited Property
Effective February 2021, Proposition 19 ended California's generous parent-child property tax exclusion for inherited properties that aren't used as the heir's primary residence. Before Prop 19, children could inherit property and keep the parent's low property tax basis regardless of use. After Prop 19, the property is reassessed to current market value unless the heir moves in within one year — often increasing annual property taxes by $10,000-$50,000+.
What Changed in February 2021
For decades before 2021, California allowed parents to transfer property to their children with the property's low assessed value preserved. A parent who bought a Los Angeles home in 1985 for $200,000 with annual property taxes of $4,000 could transfer it to their adult children at death — and the children continued paying $4,000 in property taxes despite the home now being worth $2,500,000.
This parent-child exclusion was one of the most generous property tax benefits in any U.S. state. It encouraged keeping inherited California homes in the family across generations, often as second homes, rentals, or investments.
Proposition 19, effective February 16, 2021, fundamentally changed this. The parent-child exclusion now applies only if the inheriting child makes the property their primary residence within one year of the transfer. Otherwise, the property is reassessed to current market value.
Before Prop 19 — The Old Rules
| Scenario | Property Tax Treatment |
|---|---|
| Child inherits, lives there | Original assessed value preserved |
| Child inherits, rents it out | Original assessed value preserved |
| Child inherits, uses as second home | Original assessed value preserved |
| Child inherits, leaves vacant | Original assessed value preserved |
| Child sells immediately | Reassessed at sale (normal) |
Under the old rules, the use of the property after inheritance was irrelevant. The low property tax basis transferred with the property regardless of what the inheriting child did with it.
After Prop 19 — The New Rules
| Scenario | Property Tax Treatment |
|---|---|
| Child inherits, moves in as primary residence within 1 year | Original basis preserved (with $1M value cap) |
| Child inherits, rents it out | Reassessed to current market value |
| Child inherits, uses as second home | Reassessed to current market value |
| Child inherits, leaves vacant | Reassessed to current market value |
| Child sells within 12 months | Reassessed at sale (normal) |
Note the $1M value cap: even for inheriting children who do move in as primary residence, if the property's current market value exceeds the original assessed value by more than $1 million, the excess is reassessed.
Real-World Impact
Example 1 — Pasadena Family Home
Parents bought a Pasadena home in 1985 for $300,000. Current market value: $1,800,000. Assessed value before death (after Prop 13 adjustments): $580,000. Annual property taxes before death: approximately $6,800.
Before Prop 19: Child inherits, decides to rent it out. Annual property tax: $6,800. No reassessment.
After Prop 19: Child inherits, decides to rent it out. Property reassessed to $1,800,000. Annual property tax: approximately $21,000. Increase: $14,200 per year.
If the inheriting child moves in as primary residence: original basis preserved up to $1M of excess. With excess being $1,220,000 ($1.8M market minus $580K basis), $220,000 is reassessed. New annual tax: approximately $9,400.
Example 2 — Beverly Hills Investment Property
Parents bought a Beverly Hills home in 1995 as their primary residence for $1,200,000. Current market value: $5,500,000. Assessed value at death: $1,950,000. Annual property tax: approximately $23,000.
Before Prop 19: Children inherit, keep as rental or vacation home. Annual property tax: $23,000.
After Prop 19: Children inherit, none make it primary residence. Property reassessed to $5,500,000. Annual property tax: approximately $64,000. Increase: $41,000 per year.
Strategic Implications
Selling within 12 months has become significantly more attractive. Combined with the stepped-up basis benefit, selling shortly after inheritance often produces dramatically better outcomes than keeping under the new rules.
Moving into the inherited home is now the only way to preserve the parent's property tax basis for inherited properties intended for long-term family ownership.
Rental properties owned by parents are no longer easily passed down. The economics of California rental real estate change substantially when inherited rental properties are reassessed to current market value.
Estate planning strategies have shifted. Some California families now consider selling investment properties during the parents' lifetimes and gifting cash to children, rather than passing properties at death. The right strategy depends on circumstances and should be discussed with an estate planning attorney.
For the vast majority of California heirs who don't plan to live in their inherited property, Prop 19 makes selling soon after inheritance the financially superior choice. The combination of stepped-up basis benefit and avoidance of reassessment carrying costs typically produces $50,000-$300,000+ in better outcomes versus keeping the property as a rental, second home, or vacant asset.
