Taxes on Inherited Property in California

Most people searching for taxes on inherited property in California are doing it in the middle of something much harder: a parent or spouse has died, a house now sits in their name or in a trust they are responsible for, and a brother, a sister or a surviving parent is asking what the family owes. Maybe you are the executor trying to understand what the estate faces, or a surviving spouse wondering whether the family home's property tax bill is about to change. This page lays out each tax you may have heard about, which ones actually reach an heir, and the facts that decide the answer.

What Taxes Apply — and Which Do Not — When You Inherit Property in California

Five kinds of tax tend to come up in the same conversation, and only some of them apply. An inheritance tax is a tax charged to the person who receives property because someone died. An estate tax is a tax figured on everything the person who died owned, before it passes to anyone. Property tax reassessment is the county assessor setting a new taxable value for real estate after it changes hands. Capital gains are the profit when property is sold for more than its tax cost. Income tax is the federal and California tax on income, which includes those gains.

California imposes neither of the first two. Rev. & Tax. Code section 13301 provides that neither the state nor any political subdivision of the state shall impose any gift, inheritance, succession, legacy, income or estate tax on the estate or inheritance of any person or by reason of a transfer occurring because of a death. The California State Controller's Office page on California Estate Tax states that for decedents who die on or after January 1, 2005, there is no longer a requirement to file a California Estate Tax Return.

A federal estate tax does exist, and it reaches only estates valued above a filing threshold that federal law sets for the year of death.

For most California heirs, three questions remain:

1. Property tax. Whether the county reassesses the inherited real estate, or whether a Proposition 19 exclusion keeps the prior taxable value.
2. Basis. What the property's tax cost is in the heir's hands, under the stepped-up basis rule in 26 U.S.C. § 1014(a).
3. Income tax on a sale. Whether a later sale produces a gain that federal and California income tax reach.

Receiving the inheritance itself is not income. Under 26 U.S.C. § 102(a), gross income does not include the value of property acquired by gift, bequest, devise or inheritance, although income the property later produces, such as rent, is not excluded.

Property Tax Reassessment Under Proposition 19

The property tax question usually arrives first, often as a letter from the county assessor. In California, an inheritance of real property is generally a change in ownership, which means the assessor may set a new taxable value. For a family that has paid a modest bill on a house owned for decades, that change can be the largest tax effect of the whole inheritance.

Proposition 19 governs that question for deaths on or after February 16, 2021. The State Board of Equalization's Proposition 19 page explains that the date of death is the date of the change in ownership, that Proposition 58 applies to dates of death on or before February 15, 2021, and that Proposition 19 limits the parent-child exclusion to a family home that was the parent's principal residence and becomes the child's, or to a family farm. The Board's page states that a rental home passing from parent to child would not qualify.

Under Rev. & Tax. Code section 63.2, the exclusion is allowed only when a claim is filed with the assessor, and its conditions include these:

• Occupy the home. It has to have been the transferor's principal residence and become the heir's principal residence within one year of the transfer.
• File for the exemption. The heir files for the homeowners' or disabled veterans' exemption within a year of the transfer.
• File the claim on time. The claim is due within three years after the transfer, or before the property is transferred to a third party, or before an eligible transferee no longer occupies the residence, whichever is earlier.

A claim is also timely if filed within six months after the assessor mails a notice of supplemental or escape assessment for the transfer. A late claim filed while the family still owns the property can still be considered, but the exclusion then applies only from the lien date of the assessment year in which the claim is filed.

There is also a value limit. The new taxable value is the prior taxable value, plus any amount by which the home's fair market value exceeds that taxable value plus $1,000,000, as adjusted. The State Board of Equalization's Proposition 19 Fact Sheet gives the adjusted amount as $1,044,586 for transfers from February 16, 2025, through February 15, 2027. The exclusion is removed once no eligible transferee qualifies for either exemption, and the Board's page says the home then receives a new taxable value based on its fair market value on the date it was inherited, adjusted for inflation.

Grandchildren can qualify under the same conditions only if all of the grandchild's parents who are the grandparents' children, other than stepparents, are deceased as of the date of transfer.

Separate from the claim, Rev. & Tax. Code section 480 requires a change in ownership statement. Where real property is subject to probate, the personal representative (the executor or administrator the court appoints) files it with the county recorder or assessor at or before the filing of the inventory and appraisal. In other cases, including a transfer through a trust, the trustee or the person receiving the property files it within 150 days after the date of death. All of this concerns real property; personal property such as furniture, vehicles or bank accounts is not part of a Proposition 19 claim. The county assessor's office, not a court, administers both filings and answers reassessment questions.

Stepped-Up Basis and What It Means When You Sell

Basis is the starting point for figuring gain when property is sold, roughly the property's cost for tax purposes. For inherited property, 26 U.S.C. § 1014(a) generally sets the heir's basis at the property's fair market value on the date of the decedent's death, not what the decedent originally paid. The same subsection allows other values in specific cases, including the alternate valuation date when the personal representative elects it on a federal estate tax return.

In plain terms, the clock on gain restarts at the death. Consider a hypothetical: a parent bought a house for a small fraction of what it was worth when they died. The heir's basis is the date-of-death value, so the growth during the parent's lifetime is not counted as the heir's gain. If the heir sells soon afterward for about that value, the gain may be small or nothing at all. The IRS Frequently asked questions on estate taxes page says there is usually little or no gain to account for when the sale occurs soon after the date of death.

If the property instead rises in value while the heir owns it, the increase above the stepped-up basis is a taxable gain when sold. The holding period also works in the heir's favor: under 26 U.S.C. § 1223, when basis is set by the decedent rule and the property is sold within a year after the death, the heir is considered to have held it for more than one year. The IRS Publication 559, Survivors, Executors, and Administrators describes the result as long-term gain or loss regardless of how long the heir held the property.

One exception matters for some families. Under 26 U.S.C. § 1014(e), if appreciated property was given to the decedent during the one-year period ending on the date of death and it passes back to the person who gave it or that person's spouse, their basis is the decedent's adjusted basis immediately before the death instead of the date-of-death value.

Basis is a different question from property tax. Proposition 19 decides what the county assessor taxes each year; stepped-up basis decides what gain, if any, income tax reaches on a sale. A CPA, an enrolled agent or a tax attorney is the professional who reviews the basis figure and any tax that follows from it.

California Income Tax on the Sale of Inherited Property

Once a family decides to sell, the income tax side follows the property onto two returns. A gain above the stepped-up basis is generally reported on the federal return and on the California personal income tax return, so an heir with a gain may owe both federal and California income tax. California's income tax is administered by the Franchise Tax Board, which publishes the current California rules and rates for gains from property sales.

The amount, if any, depends on facts rather than on the inheritance itself: the date-of-death value, the sale price, selling costs, and what happened to the property between the death and the sale. The IRS Gifts & inheritances frequently asked question puts the first step plainly: to determine whether a sale of inherited property is taxable, first determine the basis, and if the property sells for more than the basis, there is a taxable gain.

Who sells also matters. Publication 559 explains that when the estate is the legal owner of the decedent's residence and the personal representative sells it during administration, the tax treatment depends on how the estate holds or uses the home; where the representative intends to realize its value through a sale, the IPS publication treats it as a capital asset held for investment, which can make a loss deductible. Renting the house before a sale adds another layer, since rent the property earns is income under 26 U.S.C. § 102(b).

The choice to keep, rent or sell is a family decision with tax consequences on each path, and the keep vs. rent vs. sell comparison sets those paths side by side. The selling process itself, from listing to closing, is a separate subject. A CPA, an enrolled agent or a tax attorney can calculate the federal and California tax on a specific sale.

Federal Estate Tax: When It Applies and When It Does Not

Many families reasonably worry that a federal estate tax will take a share of the house. The IRS Estate tax page describes it as a tax on the right to transfer property at death, figured from an accounting of everything the decedent owned or had certain interests in, at fair market value. That total is the gross estate. It is a tax measured on the estate as a whole, not on each heir's share, which is what separates it from an inheritance tax.

The same IRS page says most relatively simple estates do not require the filing of an estate tax return. A return (Form 706) is required only when the gross estate, increased by the decedent's adjusted taxable gifts and specific gift tax exemption, is above the filing threshold for the year of death. The IRS publishes that threshold by year of death on its estate tax pages.

Where a return is required, the IRS FAQ page states that it is due nine months after the date of death, with an automatic six-month extension available by filing Form 4768 on or before the due date. That page also notes that a surviving spouse's benefit from the decedent's unused exclusion amount, called portability, requires a timely filed Form 706, even when no tax is owed.

A filed return can also tie heirs to the values it reports. The IRS Publication 551, Basis of Assets explains that when an estate must file Form 706, beneficiaries generally receive a Schedule A (Form 8971) from the executor reporting the estate tax value of property distributed to them, and certain beneficiaries are required to use that value as their basis. If an estate may be large enough to reach the filing threshold, an estate attorney or a CPA advises the executor on the return.

How Title and How the Property Was Held Affect the Tax Outcome

The same house can produce different tax results depending on paperwork the family may not have looked at in years. The deed, any trust document and the date of death are what a CPA or attorney asks for first.

Community property. For a married couple, 26 U.S.C. § 1014(b)(6) treats the surviving spouse's half of community property as acquired from the decedent when at least half of the community interest was includible in the decedent's gross estate. Publication 551 describes the effect in California and other community property states: the total value of the community property, even the surviving spouse's part, generally becomes the basis of the entire property. Whether a particular home qualifies depends on how title was held and on the facts behind it.

Joint tenancy. Under 26 U.S.C. § 1014(b)(9), property acquired by reason of the form of ownership is covered to the extent it is required to be included in the decedent's gross estate. How much of a jointly held home receives a new basis depends on that inclusion, which a tax professional determines.

A revocable living trust. Under 26 U.S.C. § 1014(b)(2), property the decedent placed in a trust while keeping the right to revoke it is considered acquired from the decedent, so the basis rule still applies. On the property tax side, Rev. & Tax. Code section 63.2 defines a transfer to include one through an inter vivos or testamentary trust, so the Proposition 19 analysis is the same, and the trustee files the change in ownership statement.

The date of death. A death on or after February 16, 2021, falls under Proposition 19; an earlier death follows the prior rules described above.

The facts to gather are how title was held, the date of death, whether a trust exists, and whether an heir intends to live in the property as a principal residence. Where heirs or a trustee disagree about the property, that contested matter is a different subject handled by an attorney who litigates trust and probate cases. For how the house itself passes, by trust, probate or a simplified procedure, the guide on inheriting a house in California walks through it.

What Silver Lining Estate Covers — and Where to Take the Next Step

Each tax question in this page has an office or a professional who answers it. Silver Lining Estate is a California educational resource that explains what happens after a death and the choices a family has; it does not represent anyone, give legal or tax advice, or calculate the tax for a particular estate.

• Property tax reassessment. The county assessor's office where the property is located is the first stop for a Proposition 19 claim or a change in ownership statement; a property tax consultant or an attorney handles a dispute over a reassessment.
• Income tax and basis. A CPA, an enrolled agent or a tax attorney reviews basis and the tax on a sale.
• Estate administration. A probate or estate attorney advises an executor, administrator or trustee on settling the estate, including any federal estate tax filing.

Taxes are one part of a longer sequence. The California estate settlement guide lays out the order in which an estate is settled, and the estate settlement checklist lists the tasks, including the Proposition 19 filing, in the order they usually arise.
