California has no state estate tax, no inheritance tax, and no gift tax. A beneficiary who inherits property from a California estate owes nothing to the state on that transfer, regardless of the estate’s size. Federal estate tax can still apply to very large estates, and inheriting California real estate can trigger a property tax reassessment that costs heirs far more over time than any one-time death tax would.
What California Does Not Tax
California Revenue and Taxation Code Section 13301 prohibits the state and every local government in California from imposing any estate tax, inheritance tax, gift tax, or any other tax tied to a death-related transfer of property.1California Legislative Information. California Revenue and Taxation Code RTC 13301 Voters put this rule in place through Proposition 6 in 1982, and the legislature reenacted the same language that year.
The two taxes people most often mix up work differently. An estate tax is calculated against the total value of a deceased person’s property before anything is distributed to heirs. An inheritance tax is charged to the person who receives assets, with the rate often depending on how closely they were related to the deceased. California imposes neither one.2State Controller’s Office. California Estate Tax A spouse, child, friend, or charity receiving property from a California estate owes the state nothing on the inheritance itself.
That does not mean inherited property comes with no tax consequences at all. Federal estate tax, federal income tax on income the inherited assets generate, and California’s own property tax reassessment rules can each come into play.
Federal Estate Tax Still Applies
The federal government taxes estates above a threshold called the basic exclusion amount. For 2026, that exemption is $15,000,000 per individual.3Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026, Including Amendments From the One, Big, Beautiful Bill A married couple can effectively shelter up to $30,000,000 by combining both spouses’ exemptions through portability.
Only the value above the exemption is taxed. Rates are graduated, starting at 18 percent on the first $10,000 of taxable value above the exemption and reaching 40 percent on amounts more than $1,000,000 above it.4Office of the Law Revision Counsel. 26 USC 2001 Imposition and Rate of Tax Because the exemption absorbs the lower brackets, taxable estates nearly always pay at the top rate.
The current, higher exemption originated in the Tax Cuts and Jobs Act of 2018 and was scheduled to drop at the end of 2025. The One, Big, Beautiful Bill Act, signed July 4, 2025, kept it in place.5Internal Revenue Service. One, Big, Beautiful Bill Provisions The IRS set the 2026 figure at $15,000,000, up from $13,990,000 in 2025.6Internal Revenue Service. What’s New – Estate and Gift Tax
Lifetime Gifts Share the Same Exemption
The federal estate tax and the federal gift tax work as a single unified system. The $15,000,000 exemption covers both. Lifetime gifts above the annual exclusion reduce the exemption left to shelter the estate at death, which prevents giving everything away during life as a way to escape estate tax.
Not every gift chips away at the exemption. In 2026 you can give up to $19,000 per recipient per year without using any lifetime exemption at all.3Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026, Including Amendments From the One, Big, Beautiful Bill Married couples can combine the annual exclusion to give $38,000 per recipient. Only amounts above the annual exclusion count against the lifetime number.
Stepped-Up Basis for Heirs
The single most valuable federal tax benefit for most heirs is the stepped-up basis rule. When you inherit property, your tax basis for calculating future capital gains resets to the asset’s fair market value on the date the previous owner died.7Office of the Law Revision Counsel. 26 US Code 1014 – Basis of Property Acquired From a Decedent Any appreciation that built up during the deceased person’s lifetime is never taxed as a capital gain.
Say a parent bought a home for $200,000 and it was worth $900,000 at death. The heir’s basis becomes $900,000. If the heir sells shortly after for that same amount, there is no capital gain to report. Without the step-up, the sale would have produced $700,000 in taxable gain.
Community Property Double Step-Up
California is a community property state, and that produces an extra benefit for surviving spouses. When one spouse dies, both halves of community property, not just the deceased spouse’s half, get stepped up to fair market value. In most non-community-property states, only the deceased spouse’s half gets the new basis. A surviving spouse in California can sell jointly owned community property soon after death and owe no capital gains tax on appreciation that accrued during the marriage.
One narrow exception: if someone gives appreciated property to a person who dies within one year, and the property ends up back with the original donor or the donor’s spouse, no step-up applies. The basis stays where it was in the dying person’s hands.7Office of the Law Revision Counsel. 26 US Code 1014 – Basis of Property Acquired From a Decedent
Property Tax Reassessment on Inherited California Real Estate
This is the California-specific tax that catches most families off guard. Inheriting real estate in California can send the annual property tax bill up sharply, even though no estate or inheritance tax is owed.
Under Proposition 19, which took effect in February 2021, inherited property is generally reassessed to current market value when it transfers from a parent to a child, or from a grandparent to a grandchild if the parent is already deceased.8California State Board of Equalization. Proposition 19 Fact Sheet For a home that has been in a family for decades under California’s low Proposition 13 assessments, a reassessment to current market value can multiply the annual tax bill several times over.
A limited exclusion exists for a family home. The child must move in and use the property as their own primary residence within one year of the transfer, and must file for a homeowners’ exemption or disabled veterans’ exemption within that same year. If both conditions are met, the home keeps its existing assessed value up to a cap equal to the current assessed value plus $1,044,586 (the inflation-adjusted figure for transfers through February 15, 2027). Market value above that threshold is added to the assessed value.8California State Board of Equalization. Proposition 19 Fact Sheet
If the child does not move in, say they keep the home as a rental or use it as a second house, the whole property is reassessed to current market value with no exclusion.
Out-of-State Property Can Still Owe Tax
California’s rule protects California property, not property located elsewhere. Roughly a dozen states and Washington, D.C. impose their own estate tax, and several states impose an inheritance tax. If a California resident owns real property in one of those states, such as a vacation home or rental, the estate can owe that state’s tax on the value of the property located there regardless of where the owner lived.
Exemption thresholds in those states are often far lower than the federal level. Some sit at $1 million to $2 million, so an estate too small to owe any federal estate tax can still owe state estate tax on out-of-state holdings.
When a Federal Estate Tax Return Is Required
Estates exceeding the federal exemption must file IRS Form 706 within nine months of the date of death, and any tax owed is due at the same time.9Internal Revenue Service. Instructions for Form 706 The executor identifies and values everything the deceased person owned on the date of death, including real estate, business interests, investments, accounts, and valuable personal property. Debts, funeral costs, and administrative expenses reduce the taxable value.
An executor who needs more time can file Form 4768 before the original deadline for an automatic six-month filing extension.10eCFR. 26 CFR 20.6081-1 – Extension of Time for Filing the Return The extension covers filing only. Interest on any unpaid tax keeps running from the original due date.
Portability Election for a Surviving Spouse
When a married person dies without using all of their $15,000,000 exemption, the surviving spouse can claim the unused portion. To make this portability election, the executor has to file Form 706 even if the estate is too small to owe any tax.11Internal Revenue Service. Estate Tax
The standard deadline matches the regular Form 706 deadline. For estates that were not otherwise required to file, Revenue Procedure 2022-32 gives the executor up to the fifth anniversary of the date of death to file a Form 706 solely to elect portability.12Internal Revenue Service. Revenue Procedure 2022-32 Miss that window and the only remaining path is a private letter ruling from the IRS, which is expensive and not guaranteed. Families often skip the filing because the first spouse’s estate was modest, and the surviving spouse permanently loses the extra exemption as a result.
Penalties for Filing or Paying Late
Missing the nine-month deadline without an extension triggers a penalty of 5 percent of the unpaid tax for each month or partial month the return is late, up to 25 percent.13Office of the Law Revision Counsel. 26 US Code 6651 – Failure to File Tax Return or to Pay Tax On a large estate tax bill, that reaches six figures quickly.
Interest also accrues on any unpaid tax from the original due date. For the first quarter of 2026, the underpayment rate is 7 percent, compounded daily, and it adjusts each quarter based on the federal short-term rate plus three percentage points.14Internal Revenue Service. Quarterly Interest Rates Interest and penalties run at the same time on a late-filed, unpaid return.
