If you've inherited a home in Chino, Chino Hills, Ontario, Eastvale, or Upland, you most likely owe little or no capital gains tax when you sell, thanks to a federal rule called the step-up in basis. That rule resets your taxable starting point to the home's fair market value on the date your loved one passed away, effectively erasing decades of appreciation from your tax picture. The key number that determines your tax bill isn't the sale price, it's the difference between what you sell for and that stepped-up basis.

Why Capital Gains Tax on Inherited Property in California Works Differently Than Most People Expect

Capital gains tax on inherited property in California is typically far smaller than families fear, and in many cases it's zero.

Here's why: under Internal Revenue Code §1014, property you inherit is generally assigned a new basis equal to its fair market value on the date of the previous owner's death. If your parents bought their Eastvale home in 2002 for $280,000 and it was worth $620,000 when they passed away, your basis is $620,000, not $280,000. Only appreciation above that reset figure is ever taxable when you sell.

This distinction matters enormously in San Bernardino and Riverside counties. The median sale price of existing single-family homes in San Bernardino County rose 59% over the ten-year period from January 2016 to January 2025. A home bought two or three decades ago for $200,000 could easily be worth five or six times that today. Without the step-up in basis, an heir would face tax on that entire run-up. With it, they typically owe tax only on appreciation that occurred after the date of death.

The core formula is:

Capital Gain = Net Sale Proceeds − Stepped-Up Basis

Net sale proceeds means the money you receive after paying real estate commissions, escrow fees, title charges, and other selling costs. The stepped-up basis is the date-of-death fair market value, adjusted for any capital improvements you made after inheriting.

In California, Inherited Home Gains Are Taxed at Two Levels, Federal and State

In California, inherited home gains are taxed twice, federally at preferential long-term rates of 0%–20%, and by the state as ordinary income at rates up to 13.3%. Understanding both layers helps you plan before you list.

Federal long-term capital gains rates for 2026 (Source: IRS Revenue Procedure 2025-32):

Inherited property automatically qualifies for long-term capital gains treatment regardless of how long you hold it after inheriting, a benefit that eliminates the holding-period requirement entirely. This rule is set out in IRS Publication 544, which states directly: "If you inherit property, you are considered to have held the property longer than 1 year, regardless of how long you actually held it."

California is different. The California Franchise Tax Board does not have a preferential capital gains rate. The state taxes any gain from a real property sale as ordinary income, following the state's progressive income tax brackets, which run from 1% up to 13.3% for the highest earners. For most Inland Empire families in mid-range income brackets, state tax on a modest inherited-home gain will typically fall in the 6%–9.3% range.

High earners (modified AGI above $200,000 single / $250,000 married filing jointly) may also owe an additional 3.8% federal Net Investment Income Tax on top of the capital gains rate.

A grounded Chino Hills example:

Suppose your parent's home in Chino Hills was appraised at $640,000 on the date of death. You sell it fourteen months later for $665,000. After paying 5.5% in commissions and closing costs (roughly $36,575), your net proceeds come to approximately $628,425.

In this scenario, you owe nothing in capital gains tax. Had you inherited the parent's original 1998 purchase price of $185,000 instead, the taxable gain would have been approximately $443,425, a figure that illustrates precisely why the step-up in basis is so valuable.

If you wait and sell when the home has appreciated well past the stepped-up basis, you will owe tax on the portion above that reset figure.

The Community Property Advantage Many San Bernardino County Families Miss

In California, surviving spouses who hold property as community property typically receive a full step-up in basis on the entire home, not just the deceased spouse's half, because the state treats both halves of the asset as a single unit. California is a community property state, and for married homeowners in the Inland Empire, that distinction can be worth tens of thousands of dollars.

If your parents owned their Ontario or Eastvale home as community property and your mother passes away first, your father's basis in the entire home steps up to its date-of-death value.

If he later keeps the home until his own death, the property typically receives another step-up in basis. By the time you inherit, your basis may equal current market value, leaving you with little or no taxable gain.

But it must be properly documented: if no one establishes the fair market value at the time of the first spouse's death, proving that stepped-up basis years later becomes far more difficult and expensive.

One important exception: some older estate plans from the 1990s and early 2000s include bypass trusts (also called AB trusts or ABC trusts). Assets placed into a bypass trust at the first spouse's death may not receive a second step-up when the surviving spouse passes.

If the home is held in a trust, have an estate attorney or CPA review the trust document before you list the property. Discovering a basis problem after closing is costly and often irreversible.

Proposition 19 Is a Separate, and Often Larger, Hit

Capital gains tax and California property tax are two completely different issues, and confusing them leads to expensive surprises.

Proposition 19, which California voters passed in November 2020, changed the rules for inheriting a parent's low property tax assessment. Under California State Board of Equalization guidelines, the parent-child exclusion now applies only if:

1. The home was the parent's primary residence at the time of transfer, and

2. The inheriting child moves in and claims it as their own primary residence within one year of the transfer.

Even then, if the home's fair market value exceeds its existing taxable value by more than $1,044,586 (the inflation-adjusted cap in effect from February 16, 2025 through February 15, 2027), the property is partially reassessed. If the child does not move in, the property is fully reassessed to current market value.

In practical terms for the Chino area: homes that parents purchased decades ago under Proposition 13's 1% cap often carry assessed values well below today's market. A full reassessment can mean an annual property tax bill that triples or quadruples, and this can happen even when the capital gains tax bill is zero.

The two issues run on parallel tracks:

• Step-up in basis - determines your capital gains tax when you sell

• Proposition 19 - determines the property tax assessment if you keep it

Plan both, because the wrong assumption on either can cost tens of thousands of dollars.

Gift vs. Inheritance: Why How You Received the Property Changes Everything

The step-up in basis described above applies when you inherit property after the owner's death. If a parent transferred the home to you during their lifetime, by signing a deed or adding you to title, the rules work very differently.

A lifetime gift generally carries a carryover basis: you receive the parent's original, unadjusted tax basis. Using the earlier example, that means your basis would be $185,000 rather than $640,000, and the capital gains tax bill on a sale would be dramatically higher, since the full history of appreciation becomes taxable.

In the Inland Empire, where homes that sold for $200,000–$300,000 in the late 1990s and early 2000s are now worth significantly more, this strategy often backfires badly from a tax standpoint.

Parents sometimes transfer homes during their lifetime to simplify probate, or because they believe it helps their children. A properly structured trust or estate plan typically preserves the step-up in basis far more effectively than a pre-death deed transfer. If you are uncertain how you came to own the property, or whether a trust is involved, an estate attorney or tax professional can clarify your basis before you make any decisions.

How to Protect Your Stepped-Up Basis: The Date-of-Death Appraisal

One of the most important, and frequently skipped, steps after inheriting a home is obtaining a professional appraisal establishing the property's fair market value on the date of death. This document is your evidence. It establishes the stepped-up basis you'll report on IRS Form 8949 and Schedule D when you eventually sell.

Online valuation tools are not a substitute. They are not accepted by the IRS or the California Franchise Tax Board as documentation of fair market value. A licensed appraiser's report is the standard that holds up in an audit.

Get the appraisal as close to the date of death as possible. Retrospective appraisals done years later cost more, take longer, and are harder to defend. In the Chino, Chino Hills, and Ontario area, a standard residential date-of-death appraisal typically runs $350–$550 for a single-family home, a modest cost compared to the tax exposure it protects.

Four Strategies That Can Reduce or Defer Capital Gains Tax on an Inherited Home

Four legal strategies can reduce or defer capital gains tax on an inherited home in California. Here's a quick-reference summary, followed by details on each:

Sell promptly. Because the step-up in basis resets your starting point to date-of-death value, a quick sale leaves little time for additional appreciation to accumulate. Many families who sell within months of completing the probate or trust administration process owe minimal tax.

Move in and use the home as your primary residence. Under Internal Revenue Code §121, if you live in the inherited home as your primary residence for at least two of the five years before you sell, you can exclude up to $250,000 of capital gain ($500,000 for married couples filing jointly). This requires genuine use as your main home, not simply holding title.

Consider a 1031 exchange for investment property. This option applies only if the inherited property is a rental or investment asset, not a home you or a family member lived in. If that's your situation, you may be able to defer capital gains tax by reinvesting the proceeds into another like-kind investment property through a properly structured 1031 exchange. Strict IRS deadlines apply: you must identify a replacement property within 45 days of closing and complete the exchange within 180 days.

Time the sale thoughtfully. Federal capital gains rates depend on your total taxable income. If you anticipate a lower-income year, perhaps due to retirement, a job transition, or other circumstances, selling in that year may reduce your rate or even drop you into the 0% bracket.

Frequently Asked Questions

• Do I pay capital gains tax the moment I inherit a house in California?

No. Inheriting a property is not a taxable event. Capital gains tax is only triggered when you sell the property, and only on the gain above your stepped-up basis. California does not have an inheritance tax, and the federal estate tax applies only to estates exceeding $15,000,000 in 2026 (per IRS Estate Tax guidance, reflecting P.L. 119-21 as enacted), well above the value of most homes in the area. For the vast majority of Chino, Ontario, Eastvale, and Upland families inheriting a single home, the federal estate tax simply does not apply.

• How do I calculate my capital gain when I sell an inherited home?

The formula is straightforward: Capital Gain = Net Sale Proceeds − Stepped-Up Basis. Net sale proceeds are the sale price minus commissions, escrow fees, title charges, and other selling costs. The stepped-up basis is the home's fair market value on the date of death, adjusted upward for any capital improvements you made after inheriting. Only the remaining positive number is taxable.

• What happens if multiple siblings inherit the same house?

Each heir's share of the gain is calculated separately. If you and a sibling each inherit a 50% interest and later sell, each of you reports your proportional share of the proceeds and basis on your own tax return. If only one sibling moves into the home and qualifies under the Section 121 home sale exclusion, that sibling can apply the exclusion to their share, but the co-owner who did not live there generally cannot.

• Does Proposition 19 affect my capital gains tax?

No. Proposition 19 governs property tax reassessment, whether the county assesses the home at its current market value or keeps the inherited (often much lower) assessed value. Capital gains tax is entirely separate and governed by federal and California income tax rules. You may owe little or no capital gains tax on a stepped-up-basis sale while simultaneously facing a large increase in your annual property tax bill under Proposition 19 if you keep the home.

• Is there any advantage to keeping the inherited home instead of selling right away?

Sometimes. If the home is in a strong rental market, as Inland Empire properties often are, holding it as an investment can generate monthly income.

However, renting introduces additional complexity: rental income is taxable each year, and depreciation deductions that reduce your tax during the rental period also reduce your basis. When you eventually sell, the accumulated depreciation is subject to recapture tax at up to 25% federally, on top of any standard capital gains rate, meaning the total tax bill on a long-held rental can be materially higher than on a prompt sale after inheriting. A tax professional can model both paths before you decide.

• What if my parents transferred the home to me before they died?

If the transfer was a lifetime gift, a deed signed while your parent was alive, you generally receive the parent's original adjusted basis rather than a stepped-up basis. This often results in a much larger taxable gain when you sell, because you inherit the full history of appreciation. This is one reason why outright pre-death transfers are usually less tax-efficient than a proper estate plan that preserves the step-up in basis.
