California Has No Inheritance Tax. Proposition 19 Is the Tax That Bites.

Search traffic does not lie: thousands of Californians ask every month whether the state has an inheritance tax. The answer is clean. No. California taxes neither the estate nor the people who inherit from it, and it has not since the old pick-up tax expired with the federal credit that funded it. Only five states still collect an inheritance tax in 2026: Kentucky, Maryland, Nebraska, New Jersey, and Pennsylvania. Iowa finished phasing its tax out for deaths on or after January 1, 2025. Maryland stands alone in charging both an inheritance tax and an estate tax.

The federal side is quieter than the internet suggests, too. The 2025 federal tax law set the estate and gift exemption at 15 million dollars per person, 30 million per married couple, effective for deaths and gifts in 2026, made it permanent, and indexed it for inflation starting in 2027. You will still find articles warning that the exemption drops to about 7 million dollars in 2026. That was the old law’s sunset. It was repealed; the drop never happened. The annual gift exclusion for 2026 holds at 19,000 dollars per recipient.

So if death taxes are not the problem, why do so many California families get a painful tax surprise after a parent dies?

The tax that actually bites is on the county property-tax bill

Since February 16, 2021, Proposition 19 has governed what happens to a property’s assessed value when it passes from parent to child. Before that date, a child could inherit the family home and up to a million dollars of assessed value in other property, rentals included, and keep paying property tax on the parent’s old assessed value. That world is gone.

Under Prop 19, a child keeps the parent’s low assessment only when three things are all true:

The property was the parent’s principal residence or a family farm.
The child makes it their own principal residence, moving in within one year of the transfer.
The exclusion claim, form BOE-19-P, and the homeowners’ exemption are filed within one year.

And even then the protection has a ceiling. If the home’s market value exceeds the old factored assessed value by more than the exclusion amount, currently 1,044,586 dollars for transfers between February 16, 2025 and February 15, 2027, the excess is added onto the child’s new assessed value. The figure adjusts every two years; you will still see 1,000,000 or 1,022,600 dollars quoted on pages that have not kept up. The next adjustment lands February 16, 2027.

Everything else, the rental, the vacation cabin, the second house, gets reassessed to full market value at the transfer. For inherited property the transfer date is the date of death. A duplex bought in 1985 and taxed on a 90,000 dollar assessment can arrive in a child’s hands carrying a bill computed on 950,000 dollars, year after year. That, not an inheritance tax, is the check California families actually write.

One more moving piece, reported as fact and nothing more: an initiative seeking to undo Prop 19’s parent-child changes was circulating petitions for a possible November 2026 ballot. Unless and until voters change it, the rules above control.

What this means in practice

For the estates and trusts this practice administers, Prop 19 is a deadline-and-paperwork problem before it is anything else: identifying the transfer date, calendaring the one-year occupancy and filing windows, and getting BOE-19-P and the homeowners’ exemption in front of the assessor on time. Missing the window converts a preserved assessment into a permanent, larger tax bill.

Whether to restructure ownership before death to manage Prop 19, and how a trust, an LLC, or a lifetime transfer would change the picture, are planning and legal questions, and they belong with a California estate planning attorney. Our part is the administration side: when the transfer has happened, making sure nothing with a deadline gets missed.

Questions families ask.

Does California have an inheritance tax in 2026?

No. California imposes neither an inheritance tax on the people who receive property nor an estate tax on the estate itself. The state's old pick-up estate tax died with the phase-out of the federal credit that funded it two decades ago, and nothing has replaced it. As of 2026 only five states still collect an inheritance tax: Kentucky, Maryland, Nebraska, New Jersey, and Pennsylvania. Iowa's tax ended for deaths on or after January 1, 2025, and Maryland is the only state that levies both an inheritance tax and an estate tax.

What is the federal estate tax exemption for 2026?

15 million dollars per person, 30 million dollars for a married couple, with a top rate of 40 percent above it. The 2025 federal tax law made that figure permanent, replacing the scheduled drop to roughly 7 million dollars that older articles still describe, and it will be indexed for inflation starting in 2027. The annual gift-tax exclusion for 2026 remains 19,000 dollars per recipient.

Will my children's property taxes go up if they inherit my house?

Under Proposition 19, very possibly. For transfers on or after February 16, 2021, a child keeps the parent's low assessed value only if the home was the parent's principal residence, the child makes it their own principal residence within one year, and the homeowners' exemption is claimed within that year. Even then the protection is capped: if the home's market value exceeds the old assessed value by more than the current exclusion amount, 1,044,586 dollars for transfers between February 16, 2025 and February 15, 2027, the excess is added to the new assessed value.

What happens to an inherited rental or vacation home under Prop 19?

Full reassessment to market value as of the transfer, which for an inherited property means the date of death. The old parent-child exclusion that once covered a million dollars of any property is gone for transfers on or after February 16, 2021. Only a principal residence that becomes the child's principal residence, or a family farm, qualifies for any exclusion at all, and the exclusion ends if the child later stops living there.

Is there a deadline to claim the Prop 19 parent-child exclusion?

Yes, and missing it is expensive. The child must file the claim, form BOE-19-P for parent-child transfers, with the county assessor, must occupy the home as a principal residence, and must file for the homeowners' or disabled veterans' exemption within one year of the transfer date. For inherited property the transfer date is the date of death, not the date the deed gets around to being recorded, so the clock is often shorter than families realize.
