California Legal Implications: Rising Property Taxes and the Impact on Inheritance
A recent analysis of property tax trends across the United States has identified Marin County, California, as one of the nation’s most expensive areas for homeowners. According to a CBS News report, the median property tax bill in the U.S. jumped 30% between 2019 and 2024, with soaring home values driving assessments higher. While New York and New Jersey dominate the list of highest-tax counties, California’s own Marin County ranks among the top 16 counties where typical homeowners pay more than $10,000 annually., the median property tax bill in the U.S. jumped 30% between 2019 and 2024, with soaring home values driving assessments higher. While New York and New Jersey dominate the list of highest-tax counties, California’s own Marin County ranks among the top 16 counties where typical homeowners pay more than $10,000 annually.
For California residents, specifically those in high-value counties, this data highlights a critical issue in estate planning: the risk of property tax reassessment upon the death of a homeowner. Under current California law, passing a family home to the next generation involves complex tax rules that can jeopardize a family’s ability to keep the property.
The Role of Proposition 13 and Proposition 19
To understand why high property values in California matter for estate planning, one must look at how property taxes are calculated. Proposition 13 historically protected homeowners by capping property taxes at 1% of the assessed value and limiting annual increases to 2%. This means a home bought decades ago for $200,000 might still have a low tax basis, even if the current market value is $2 million. historically protected homeowners by capping property taxes at 1% of the assessed value and limiting annual increases to 2%. This means a home bought decades ago for $200,000 might still have a low tax basis, even if the current market value is $2 million.
However, the introduction of Proposition 19 significantly changed how these low tax bases are transferred to heirs. Previously, parents could transfer a home to their children without triggering a reassessment to current market value. Today, to avoid a full reassessment and a massive spike in property taxes, the heir must meet strict criteria:
* The property must be the principal residence of the transferor.
* The heir must make the property their principal residence within one year.
* There is a cap on the excluded value (current taxable value + $1 million). significantly changed how these low tax bases are transferred to heirs.

High Valuations and Probate Costs
The report notes that rising home values are the primary driver of higher taxes. In California, high property values also lead to higher probate fees if a homeowner dies without a Trust. fees if a homeowner dies without a Trust.
California probate fees are statutory and calculated based on the gross value of the estate, not the equity. For a home in Marin County or similar high-value areas worth $1.5 million, statutory probate fees for the attorney and the executor can exceed $28,000 each, even if the homeowner had a large mortgage.
Estate Planning Strategies for Homeowners
Given the rising tax environment described in the news report, California families should consider the following legal protections:
* Revocable Living Trusts: By placing a home in a Trust, families can avoid the expensive and time-consuming probate court process. This preserves liquid assets that heirs may need to pay property taxes or maintenance costs.
* Proposition 19 Compliance: An estate planning attorney can help draft documents to document intent regarding the transfer of a primary residence, ensuring heirs understand the residency requirements to keep the lower tax base.
* Liquidity Planning: Because property taxes can spike if Prop 19 requirements are not met, estate plans should account for how heirs will pay these ongoing costs, potentially through life insurance trusts or liquid asset distribution.: Because property taxes can spike if Prop 19 requirements are not met, estate plans should account for how heirs will pay these ongoing costs, potentially through life insurance trusts or liquid asset distribution.
