Many California families expect to pass the family home to the next generation. Since Proposition 19 took effect, an estate plan that once worked as intended can now leave heirs facing a significant property tax increase. In areas where home values have risen dramatically, those higher taxes may make it difficult for a child to afford to keep the home, forcing a sale that no one intended.
If your estate plan was created before Prop 19, it may be time to review whether it still reflects your family’s goals.
What Is Proposition 19?
Proposition 19, which took effect in 2021, changed how California treats property tax assessments when real estate passes from parents to children. Before the law changed, many inherited homes kept their existing assessed value, allowing families to continue paying much lower property taxes.
A parent-to-child transfer may still qualify for limited property tax relief, but only if specific requirements are met. In most cases, the child must make the home their principal residence. If the statutory requirements are met, California generally allows the home’s existing taxable value to transfer, along with an exclusion of up to an additional $1 million, adjusted for inflation every two years. If the home’s fair market value exceeds that limit, the excess may be added to the property’s taxable value, increasing future property taxes.
For families in Southern California, where homes often appreciate substantially over time, that reassessment can increase annual property taxes by thousands of dollars.
When Does Property Tax Reassessment Happen?
In most cases, a child who inherits a home must move into the property as their principal residence and claim the homeowners’ exemption within one year of the transfer. Missing that deadline can cause the family to lose the available property tax exclusion, even if the child ultimately lives in the home.
Common situations that may trigger reassessment include:
- The child does not establish the home as their principal residence and claim the homeowners’ exemption within the required one-year period.
- The home’s fair market value exceeds the available exclusion amount.
- The property is transferred in a way that does not meet California’s eligibility requirements.
Many families assume that transferring property through a will or trust automatically avoids reassessment. Unfortunately, that is not how Prop 19 works. The tax consequences depend on how the transfer is structured, whether the statutory requirements are met, and whether the deadlines are satisfied.
Can a Trust Prevent the Prop 19 Trap?
A revocable living trust remains one of the most effective estate planning tools, but it does not automatically prevent property tax reassessment.
Instead, a properly drafted trust can help by:
- Keeping ownership organized and avoiding probate.
- Providing clear instructions for how the property should be managed.
- Coordinating the transfer with your broader estate planning goals.
- Reducing the risk of mistakes that could affect eligibility for available tax benefits.
A trust is only part of the equation. How the property is transferred and used after inheritance also affects whether reassessment occurs.
Why Older Estate Plans May No Longer Work
Many estate plans prepared before 2021 assumed that children would inherit a home without triggering a major increase in property taxes. That assumption is no longer reliable.
If your estate planning documents have not been reviewed since Prop 19 became law, they may no longer achieve the results you intended. For example, your plan may successfully transfer your home to your children while also leaving them with property taxes they cannot reasonably afford.
This is especially important if:
- You own a long-held California residence with significant appreciation.
- You intend for your children to keep the family home.
- Your estate includes multiple real estate holdings.
- Your trust has not been updated in several years.
Reviewing your plan now gives you the opportunity to evaluate whether your current strategy still supports your family’s long-term goals.
What Should California Homeowners Do Now?
Every family’s situation is different, and there is no one-size-fits-all solution under Prop 19. The best approach depends on your property’s value, your children’s plans for the home, and your overall estate planning objectives.
Waiting until after your death leaves your heirs with fewer options. Planning ahead lets us evaluate strategies while you still have flexibility.
Don’t Let Property Taxes Decide Your Family’s Future
Passing your home to the next generation should include a plan that helps them afford to keep it. If your estate plan was created before Proposition 19, now is a good time to review whether it still works under today’s property tax rules.
