Prop 19 Inheritance Rules: What Your Children Actually Inherit Now
A lot of Bay Area parents believe their children will inherit their low property tax base right along with the house. Since February 2021, that assumption has created some very expensive surprises for families who did not plan ahead.
The short answer: under Prop 19, your children can still receive your low property tax base in many cases, but the rules are significantly tighter than they used to be. The transfer only works for a home the child actually lives in, it has dollar amount limits based on the gap between your assessed value and current market value, and it does not apply at all to rental properties or vacation homes.
I'm Katrina Carter, an East Bay broker and loan officer who specializes in helping longtime homeowners make smart decisions about their equity and their estate. I am not an attorney or a CPA, but I work alongside them regularly and I want to help you understand the basics so you can ask the right questions with your advisors.
1. What Changed When Prop 19 Took Effect
Before Prop 19 went into effect on February 16, 2021, California parents could pass almost any property to their children with the full property tax base intact, regardless of how the child planned to use the property. A home assessed at $300,000 in 1992 could be inherited by an adult child who already owned their own home, rented the inherited property out, and continued paying taxes on that $300,000 base indefinitely.
Prop 19 ended that. Today, the tax base transfer only applies to a home that the inheriting child uses as their primary residence, and they must move in within one year of the date of inheritance.
2. The Cap That Most Families Miss
Even when a child does move into the inherited home and qualifies for the exclusion, there is now a dollar limit on how much of the tax savings carries over.
If the home's fair market value at the time of death is more than $1,000,000 above the parent's assessed value, the child's new tax base is adjusted upward. The formula works like this: the new assessed value equals the fair market value at death minus $1,000,000.
Here is what that looks like in practice. Say your home was assessed at $400,000 when you purchased it in 1988 but is now worth $2,200,000. The gap between market value and assessed value is $1,800,000. Because that gap exceeds $1,000,000, the child's new assessed value would be $2,200,000 minus $1,000,000, which equals $1,200,000. That is still a meaningful savings compared to paying taxes on the full $2,200,000, but it is no longer the original $400,000 base your family has held for decades.
3. Rental Properties and Vacation Homes
This is where the change hits hardest for many East Bay families. If you own a rental property, a second home, or any real estate beyond your primary residence, none of those qualify for the tax base transfer. When your children inherit those properties, the county reassesses them at full current market value.
In some cases, families have seen annual property tax bills on inherited rental properties increase by tens of thousands of dollars overnight. Properties that had been held for 30 or 40 years and were part of a family income strategy are suddenly carrying a tax burden that does not pencil out.
4. The Exclusion Is Not Automatic
Your heirs must actively file for the exclusion with the county assessor. If they miss the deadline or do not know to file, they lose it. Make sure your estate documents include clear instructions for your children about what to do and when. Your estate planning attorney can build this into the plan so nothing falls through the cracks.
5. What to Do Now If This Affects You
If you own property in the East Bay that has significant appreciation, this is a conversation to have with your CPA, your estate planning attorney, and your real estate advisor together. Sometimes selling during your lifetime and gifting or distributing the proceeds is the better financial outcome for your family. Sometimes holding makes more sense. The answer depends entirely on your specific numbers, your family situation, and what your children actually want to do with the property.
I recently worked with a client in the Lamorinda area who owned her primary home and a nearby rental property she had held for over 20 years. When we walked through how Prop 19 would treat each property differently at the time of her death, she decided to sell the rental while she could still access the capital gains exclusion herself. Her children received a meaningful financial gift instead of a property carrying a significant annual tax burden they had not planned for.
Frequently Asked Questions
Does Prop 19 apply to transfers made during the parent's lifetime?
No. The Prop 19 inheritance rules apply to transfers at death. Transfers made while you are alive are handled differently and carry their own tax implications. Talk to your CPA about the specific options for your situation.
Can my child rent out the home after inheriting it?
If they want to keep the low tax base, they need to live in the home as their primary residence. If they convert the inherited home to a rental after moving in, the exclusion ends and the county reassesses the property.
What if my home is held in a trust?
Property held in a trust still gets reassessed at death unless the inheriting child qualifies for the exclusion and files for it properly. The structure of the trust matters, and you should work with an estate planning attorney who understands how your specific trust document interacts with current Prop 19 rules.
