California Estate Tax: What Families and Heirs Should Know
Understanding California Estate Tax
Last reviewed: October 2026. Publish this date after a tax editor confirms the federal 2026 threshold and California guidance below. Review at least annually and whenever relevant law changes.
Does California have an estate tax?
No current California estate tax applies to people who die today. California stopped requiring estate-tax returns for deaths on or after January 1, 2005, after the federal state-death-tax credit was phased out. The State Controller’s historical program page also notes that it continues to collect certain legacy inheritance taxes for people who died before June 8, 1982. That historical collection does not mean California has a current inheritance tax. [1]
This is a state-level answer. It does not eliminate possible federal estate-tax obligations, income-tax filings by an estate or trust, or property-tax consequences when real estate changes hands.
Estate tax and inheritance tax are different
An estate tax is imposed on the transfer of a deceased person’s taxable estate. An inheritance tax, where a jurisdiction imposes one, is generally associated with property received by beneficiaries. California currently imposes neither tax on a death occurring today. [1] [2]
If the person who died lived in another state, or the estate owns property outside California, check the rules of each relevant jurisdiction. A California resident’s heirs should not assume California’s treatment controls property or estate matters elsewhere.
For broader background, see Robert Hall’s inheritance-tax explainer. Inheritance-tax laws and the person responsible for a tax vary by jurisdiction.
Federal estate tax can still apply to a California estate
Federal estate-tax rules apply regardless of whether the person lived in California. For someone who dies in 2026, the federal filing threshold is $15 million for a U.S. citizen or resident. The filing test generally compares the gross estate, increased by adjusted taxable gifts and the specific gift-tax exemption, with the threshold for the year of death. The gross estate can include more than probate property, so the total should not be equated with the value of assets passing under a will. [2]
The $15 million figure is specific to 2026. It is not a permanent threshold, and it is not a guarantee that no federal return is needed below that amount. An estate may need to file Form 706 to elect portability for a surviving spouse even when the estate is below the filing threshold. [2] [3]
Portability for a surviving spouse
Portability is a federal election that can allow a surviving spouse to use a deceased spouse’s unused federal estate-tax exclusion. It is not automatic: the estate generally must file a properly prepared Form 706 to make the election. The ordinary filing deadline is nine months after death, and an extension may be requested. Special late-election relief may be available to some estates, but eligibility and filing requirements are specific. [3]
For a couple whose spouses die while the 2026 $15 million threshold applies, portability may make as much as $30 million of combined exclusion available in principle. That is not a blanket guarantee of a $30 million tax-free transfer: prior taxable gifts, the amount of exclusion actually unused by the first spouse, a valid election, and the law in effect at each death all matter. [2] [3]
Other tax issues that can arise after a death
Estate and trust income-tax returns
An estate or trust may earn income after a death. California’s fiduciary income-tax filing rules are separate from the state’s estate-tax rules. The Franchise Tax Board lists circumstances in which an estate or trust may need to file a California fiduciary return, including California residency or California-source income. Form 541 is used to report income received by an estate or trust and income distributed to beneficiaries when a return is required. [4]
An estate’s filing obligation depends on its income, residency, source of income, distributions, and other facts. For help understanding the difference between a transfer-tax question and a fiduciary return, see Robert Hall’s information about estate and trust tax planning and preparation.
Inherited property and later capital gains
Receiving inherited property is different from selling it later. A later sale may produce a taxable gain or loss. The recipient’s basis is determined under rules that can differ from the deceased owner’s original cost; for many inherited assets, date-of-death fair market value is relevant, subject to exceptions and reporting requirements. Keep appraisals, estate records, and improvement documents, and confirm the correct basis before reporting a sale. [6]
California property-tax reassessment
Property-tax reassessment is not an estate or inheritance tax. However, an inherited home or other California real property may be reassessed under separate change-in-ownership rules. Proposition 19 narrowed the parent-child and grandparent-grandchild exclusions. In general, a qualifying family home must be the principal residence of both transferor and transferee; a family farm may also qualify. The exclusion is subject to a value limit and filing requirements, while other real property generally does not receive the same parent-child exclusion. Check the Board of Equalization and the county assessor for the current requirements before relying on an exclusion. [5]
Robert Hall’s estate-planning services page provides more information about planning considerations. Property transfers and legal documents should be reviewed with the appropriate tax and legal professionals before action.
Practical next steps for an executor or family
Start by identifying where the deceased person was domiciled, where real estate and other significant assets are located, and whether assets were held individually, jointly, in a trust, or through beneficiary-designated accounts. Those details affect which assets may be included in a federal gross-estate calculation and which returns may be required. [2] [3]
For a 2026 death, compare the federal filing threshold with the gross estate and adjusted taxable gifts, and consider whether a Form 706 portability election is appropriate even if no federal estate tax appears due. Separately, determine whether the estate or trust has income that requires a California fiduciary return, and check with the county assessor about any inherited-property exclusion. [2] [3] [4] [5]
Keep valuations and supporting records. IRS guidance explains that basis is used to calculate gain or loss when property is later sold, and special rules apply to inherited property. [6]
Frequently asked questions
Does California charge inheritance tax when a beneficiary receives money or property?
California does not impose a current inheritance tax on a death occurring today. The State Controller’s page describes legacy collections for deaths before June 8, 1982; that historical rule does not apply to current deaths. [1]
What is the federal estate-tax threshold for someone who dies in 2026?
The federal filing threshold is $15 million for a U.S. citizen or resident who dies in 2026. The filing test includes the gross estate and certain adjusted taxable gifts, so it is not necessarily the same as the probate inventory or the amount an heir receives. [2]
Does a surviving spouse automatically inherit the first spouse’s unused federal exclusion?
No. Portability generally requires the deceased spouse’s estate to file Form 706 and make the election. The ordinary deadline is nine months after death, although an extension or limited late-election relief may be available under IRS rules. [3]
Can an estate owe California income tax even though California has no estate tax?
Yes. Estate and trust income-tax filing is a separate issue. Depending on facts such as California residency, California-source income, income amounts, and distributions, a fiduciary return may be required. [4]
Can an inherited California home be reassessed?
Possibly. California property-tax reassessment rules are separate from estate and inheritance taxes. Proposition 19 provides a limited exclusion for qualifying family homes and farms, subject to occupancy, value, and filing requirements; other inherited real property may be treated differently. Confirm the facts with the county assessor. [5]
