When a person inherits property in California, one of the first questions that arises is how the state’s property tax system will treat the transfer. California’s property tax landscape is shaped largely by Proposition 13, which caps the general levy at one percent of assessed value and limits annual increases to two percent until the property changes ownership. Historically, a change of ownership triggered reassessment at current market value, which could cause a dramatic jump in taxes for heirs. Over the years, the legislature created parent-child and grandparent-grandchild exclusions that allowed certain inherited homes to keep the lower, older tax basis. However, Proposition 19, approved by voters in 2020, significantly narrowed those exclusions beginning in February 2021, and understanding the current rules is essential for anyone planning an inheritance.
Under the rules now in effect, a family home can still transfer between parents and children, or grandparents and grandchildren, without a full reassessment, but only if the child or grandchild uses the home as their principal residence. Even then, the exclusion is not unlimited. The taxable value of the inherited home remains at the parent’s assessed value plus up to one million dollars of the difference between that value and the home’s fair market value at the time of transfer. Any appreciation beyond that threshold is added to the assessed value, which means a valuable home in a market like the Bay Area or Los Angeles may still see a substantial tax increase. For inherited properties that are not the heir’s principal residence, such as rental units, second homes, or vacant land, the parent-child exclusion generally no longer applies, and the property is reassessed at market value.
Heirs should also be aware of the interaction between property tax and income tax. California does not impose its own inheritance tax, and the federal estate tax exemption is high enough that most estates are unaffected. For income tax purposes, inherited property generally receives a stepped-up basis equal to fair market value on the date of the decedent’s death. That step-up applies for both federal and California income tax purposes, meaning that if the heir sells the property soon after inheriting it, there is often little or no capital gain. If the heir holds the property for years before selling, only the appreciation after the date of death is taxed as capital gain. California taxes capital gains as ordinary income, with rates that can reach into the double digits for high earners, plus the federal rate, so the timing of a sale matters.
Practical steps can help heirs avoid surprises. Filing the appropriate claim for the parent-child or grandparent-grandchild exclusion with the county assessor is time-sensitive, generally within three years of the transfer, and missing the deadline can forfeit the benefit. Keeping records of the home’s use as a principal residence and obtaining a professional appraisal as of the date of death support both the property tax claim and the income tax basis. Because the rules are complex and the stakes are high, consulting a California attorney or tax professional before or shortly after an inheritance is wise.
