When you sell an inherited California home, the tax question usually turns on the gap between two numbers: what the house sells for and what it was worth on the day the owner died. That date-of-death value generally becomes your starting basis, so any gain is generally measured from it, not from the full price.

Most people facing this question are holding a parent's house, or a share of one, and have just heard two very different figures: an appraisal from the estate paperwork and a price from a buyer or an agent. Siblings may be asking whether selling will create a large tax bill, and the person handling the sale may live hundreds of miles from the property. This page sets the two numbers side by side, explains where each comes from in California, and shows how the way a family sells changes what it keeps without changing the tax rule.
Two Numbers That Determine Your Tax Outcome
The sale price is the gross amount a buyer pays for the property at closing, before commissions, loan payoffs or any other costs come out. The date-of-death value is the fair market value of the property on the day the owner died. The IRS's estate tax FAQ quotes the regulation that defines fair market value as "the price at which the property would change hands between a willing buyer and a willing seller, neither being under any compulsion to buy or to sell."
The second number matters because of basis, the starting figure from which gain or loss is measured. Under 26 U.S.C. § 1014(a), the basis of property acquired from a decedent is generally its fair market value at the date of death, or, where the alternatives in that subsection apply, a value set under an alternate valuation election or the other special rules it lists. In plain words, the heir's starting point is the house's value at death, not what the parent paid decades ago. That reset is called a step-up in basis.
26 U.S.C. § 1001(a) defines gain as the excess of the amount realized over the adjusted basis, and loss as the reverse. So the gap, not the full price, is what can produce a gain.
The person selling may be an executor or administrator acting for a probate estate, a successor trustee (the person who takes over managing a trust after the person who made it dies), or an heir who now owns the house directly. The tax rule above is the same idea for each; who signs and who reports the sale depends on how title passed.

California income tax on any gain is administered by the Franchise Tax Board. How California treats basis on a state return is a question a CPA, an enrolled agent or a tax attorney reviews with the actual figures.
How Date-of-Death Value Is Established
The appraisal behind this figure looks backward. It asks what the house would have sold for on the date of death, using sales and market conditions from that time, not from the day the appraiser visits.
In a probate estate, Probate Code section 8800 requires the personal representative (the executor or administrator the court has authorized to act for the estate) to file an inventory and appraisal of estate property in a single document. It is due within four months after letters are first issued to a general personal representative, and the court may allow further time that is reasonable in the particular case. Except as a statute provides otherwise, Probate Code section 8902 has the personal representative deliver the inventory to the probate referee the court designates, who appraises all property the personal representative did not appraise. Real estate is generally appraised by the referee. A family working through this stage often finds the steps of selling during probate in California running alongside the appraisal.
For trust property and other transfers outside probate, a written appraisal as of the date of death serves the same purpose. The IRS's Publication 551 adds that where an estate files Form 706, beneficiaries generally receive a Schedule A (Form 8971) reporting the estate tax value, and certain beneficiaries must use that value as their initial basis; without a Schedule A, basis can be determined using the appraised value at death for state inheritance or transmission tax purposes.
The same date-of-death value can also matter to the county assessor, a separate question taken up below. A CPA, an enrolled agent or a tax attorney reviews the basis question; the county assessor's office handles reassessment.
What Drives the Gap Between Sale Price and Date-of-Death Value
Time and the house itself drive the gap. Four situations show how.
A sale close to the death. If the house sells soon at or near its date-of-death value, the gain is small or zero. The IRS's estate tax FAQ says much the same: there is usually little or no gain if the sale occurs soon after the date of death.
A rising market. If the house gains value between the death and the sale, the gain is generally that rise, not the full price.
A falling market or a worn house. A sale for less than the date-of-death value may produce a capital loss. The IRS's Publication 559 explains that when an estate owns a decedent's residence and the personal representative sells it intending to realize its value, gain or loss is capital gain or loss "which may be deductible." Whether a loss is deductible, and by whom, is a question for a CPA or tax attorney.
Costs and improvements. Commissions, closing costs and improvements made after the death are categories a CPA or enrolled agent looks at when working out the amount realized and the adjusted basis.
A hypothetical, not a real sale: a home appraised as of the date of death at a given figure sells a year later for more. The amount above the appraisal, adjusted for the costs a tax professional allows, is the measure of gain, not the whole price.
Timing has one more effect. Under 26 U.S.C. § 1223, property whose basis is set under § 1014 and that is sold within one year after the death is treated as held for more than one year; Publication 559 states that gain or loss on inherited capital assets is long term regardless of how long they were held.
California Property Tax Reassessment and the Date-of-Death Value
This is a different tax, decided by a different office. Rev. & Tax. Code section 60 defines a change in ownership as a transfer of a present interest in real property, including its beneficial use, worth substantially the same as the full ownership. A transfer at death can be one, and it can lead the county assessor to reassess the property to a new value.
Paperwork comes first. Under Rev. & Tax. Code section 480, the personal representative files a change in ownership statement in each county where the decedent owned real property subject to probate, before or when the inventory and appraisal is filed. In other transfers at death, including through a trust, the trustee or the transferee files it within 150 days after the date of death.
For transfers on or after February 16, 2021, Rev. & Tax. Code section 63.2 excludes some parent-child and grandparent-grandchild transfers from reassessment, in whole or in part, when a claim is filed. For a home, the conditions include that it was the transferor's principal residence, that it becomes the transferee's principal residence within one year, and that the transferee files for the homeowners' or disabled veterans' exemption within a year. The section also compares the home's market value with its prior taxable value plus a set amount, so a higher-value home may be partly reassessed; the county assessor publishes the current figures. A claim is generally due within three years after the transfer, or before a transfer to a third party, or before an eligible transferee stops living there, whichever is earlier.
Families who sell rather than move in will find the exclusion's conditions tied to occupancy. The county assessor's office processes the claim on a form the State Board of Equalization prescribes; reassessment questions go to that office. Practices in one county are described in the guide to inherited property in San Diego County.
How the Sale Method Affects What You Net — Not What You Owe in Tax
The tax rule follows the price and the basis, not the route to closing. A family with three heirs and one house is really comparing what each route leaves after costs, and how much work and uncertainty each carries.
Listing with a licensed real estate agent. This tends to reach the widest pool of buyers and may bring a higher gross price. It usually involves a commission, preparing the house, showings, and waiting on a buyer's loan approval. It tends to fit when the house is in showable shape and the estate can carry the costs while it is marketed.
Selling without an agent. The owner avoids a listing commission but handles pricing, marketing, disclosures and negotiation directly. It tends to fit when a seller has time, is near the property, or already has a buyer, such as a neighbor or relative.
A direct sale to a buyer who takes the house as it is. The buyer accepts the property in its present condition. A direct offer is often lower than an open-market sale price, because that buyer takes on the repairs, the risk and the cost of reselling; the seller gets less preparation, fewer showings and less dependence on a buyer's financing. It tends to fit when repairs are large, the heirs are far away, or certainty matters more than the last dollar. Silver Lining Inherited Property can make an offer on an inherited property for a direct as-is sale, and asking for one carries no obligation to sell.
No route changes the estate's authority to sell, any court step, required notice, disclosure duty, lien payoff or tax. Comparing written offers and estimated net proceeds, the price less commissions, repairs, carrying costs, loan payoffs and closing costs, is how a family tells which way fits.

Frequently Asked Questions
What is the stepped-up basis for inherited property?
It is the reset of the heir's starting figure to the property's fair market value at the date of death, under 26 U.S.C. § 1014(a), with the alternatives that subsection allows. It replaces what the decedent paid, so gain is generally measured only from that value.
What happens if I sell an inherited California property for more than its date-of-death value?
The amount above your basis is generally the gain, not the full price. The IRS's FAQ on sales of inherited property says that selling for more than your basis produces a taxable gain. A CPA or tax attorney reviews the actual figures and costs.
What happens if the sale price is lower than the date-of-death value?
A sale below basis may produce a capital loss. Whether it is deductible depends on facts such as who owns the property and how it was held, which a CPA, enrolled agent or tax attorney reviews.
Who determines the date-of-death value of an inherited property?
In a probate estate, the value comes through the inventory and appraisal, with the probate referee appraising property the personal representative does not, as described above. Outside probate, an appraisal as of the date of death typically supplies it; where an estate tax return is filed, certain beneficiaries must use the value it reports as their basis.
Does the way I sell the property affect what I owe in tax?
No. Listing, selling yourself or selling directly does not change the rule that gain is the amount realized over basis. The method changes the price and the costs, and so what the family keeps.
Is the date-of-death value the same as the assessed value for California property tax?
Not necessarily. Basis is an income-tax figure, while the assessed value is set by the county assessor, who may reassess after a change in ownership unless an exclusion applies. Questions about reassessment go to the county assessor's office.
What is the Proposition 19 parent-child exclusion and how does it relate to the date-of-death value?
It is the exclusion from reassessment in Rev. & Tax. Code section 63.2 for qualifying transfers on or after February 16, 2021, with the residence and claim conditions described earlier. It affects property tax only, not the income-tax basis.
Does a rise in property value after the date of death increase the heir's tax basis?
No. Basis is set as of the date of death, or an alternate valuation date where that election under 26 U.S.C. § 2032 is made. A later rise becomes part of the gain when the property sells.
