Capital Gains Taxes and the Stepped-Up Basis When Selling an Inherited California House

When you inherit a California home, the idea of a massive tax bill on decades of appreciation can be daunting. However, a federal tax rule known as the stepped-up basis often dramatically reduces, or even eliminates, what you owe. In California, this is further impacted by community property laws and the state’s unique Probate Referee system—details often missed in generic tax advice. Understanding how capital gains taxes and the stepped-up basis truly work for an inherited California house can save you tens of thousands of dollars. In this blog post, California probate real estate expert Dallas Seely discusses these tax advantages and how to maximize them when selling an inherited property.

Key Takeaways

  • The stepped-up basis resets the property’s cost basis to its fair market value on the date of death, erasing taxable gains on all prior appreciation.
  • California’s community property laws can provide a “double step-up” for surviving spouses, potentially eliminating capital gains on the entire property.
  • The California Probate Referee system, a unique state process, establishes the official date-of-death value that becomes your new basis.
  • Selling efficiently with a probate specialist minimizes the time between inheritance and sale, which in turn limits the taxable gain that can accumulate.

4 Things

You Cannot Get From Anyone Else in California

Most agents can list a property. Very few can solve the problems that come with probate. These are the advantages Dallas provides that others simply can’t.

When the right person is guiding you, everything changes.

Ready to put these advantages to work?

Upon inheriting a California home, its cost basis is “stepped up” to the fair market value on the date of the original owner’s death, not what they initially paid. This means heirs typically owe capital gains tax only on value gained after the date of death. Selling the property quickly and efficiently is key to minimizing this post-inheritance appreciation and maximizing your tax savings.

Capital Gains Tax on Inherited California Property: Step-by-Step Calculation Guide

1

Establish Date of Death FMV

The “stepped-up basis” is the property’s Fair Market Value (FMV) on the date of the owner’s death. In California, a court-appointed Probate Referee determines this official valuation.

Example (LA County)

Original Purchase (1995): $250,000

Stepped-Up Basis (2024 FMV): $850,000

2

Calculate Taxable Gain

Taxable Gain = Sale Price – Stepped-Up Basis – Selling Costs. This is where the step-up provides massive savings.

With Step-Up Basis

$900k – $850k – $27k = $23,000 Gain

Without Step-Up Basis

$900k – $250k – $27k = $623,000 Gain

3

Apply Applicable Tax Rates

The total tax is a combination of federal and state rates applied to the taxable gain. The combined maximum rate is approximately 37.1%.

  • Federal CGT: 0%, 15%, or 20%
  • California State Tax: Up to 13.3%
  • Net Investment Income Tax (NIIT): 3.8%

Realize the Tax Savings

The difference in tax owed is staggering. The stepped-up basis can save heirs hundreds of thousands of dollars.

Total Estimated Tax Savings

$222,600

($231,133 tax without step-up vs. $8,533 with step-up)

Tax Savings Comparison: California Metro Areas

Metro Area 1990s Purchase Price 2024 Median (Est. FMV) Taxable Gain (No Step-Up) Est. Tax Without Step-Up Est. Tax With Step-Up
Los Angeles $200,000 $850,000 $650,000 $241,150 Low / None
Orange County $220,000 $950,000 $730,000 $270,830 Low / None
San Diego $190,000 $820,000 $630,000 $233,730 Low / None

What Is the Stepped-Up Basis and Why Does It Matter for Inherited California Homes?

Under IRC § 1014, the cost basis of an inherited property resets to its fair market value on the date of the original owner’s death. This single rule eliminates capital gains tax liability on all appreciation that occurred during the decedent’s lifetime. The probate process in California is the legal pathway through which inherited property transfers to heirs, and the stepped-up basis applies whether the property moves through full probate, trust administration, or another transfer mechanism.

To illustrate the impact with real California numbers: if a parent purchased a Los Angeles home in 1993 for $200,000 and it was worth $850,000 at death, an heir who sells for $855,000 owes capital gains tax on only $5,000 of gain—not $655,000. That difference, taxed at California’s combined maximum rate of approximately 37.1%, represents over $240,000 in potential tax savings.

Additionally, inherited property automatically qualifies for long-term capital gains treatment regardless of how long the heir held it. Federal long-term rates are 0%, 15%, or 20% based on income. California taxes capital gains as ordinary income at rates up to 13.3%. High-income heirs may also owe a 3.8% Net Investment Income Tax.

California’s Community Property Advantage: The Double Step-Up

California is a community property state, which creates a significant additional benefit for surviving spouses. When a married couple holds property as community property and one spouse dies, both halves of the property receive a stepped-up basis—not just the deceased spouse’s 50% share. This “double step-up” can completely eliminate capital gains even on highly appreciated properties.

How California’s Probate Referee System Determines Your Stepped-Up Basis

In California, the stepped-up basis is not just an estimate from a private appraiser. California Probate Code §§ 8800-8980 require that most probate estates use a court-appointed Probate Referee to establish the official date-of-death valuation for real property. The Probate Referee’s assessed value becomes the official stepped-up basis for the inherited property.

If an heir believes the assessment is too low, which could lead to a higher taxable gain upon sale, they have the right to challenge it. The referee’s fee is typically just 0.1% of the appraised value, a small cost for establishing such a critical tax figure.

One thing families often don’t realize is that every month between the date of death and the sale closing creates additional taxable gain above the stepped-up basis. Our system of multiple offers within 24 hours and closing in as little as 2 weeks can make a meaningful difference in the final tax bill—on top of eliminating the cost and stress of repairs and showings.” — Dallas Seely

The Independent Administration of Estates Act and Timelines

The Independent Administration of Estates Act (IAEA), found in California Probate Code §§ 10400-10592, allows a personal representative to sell real property without court confirmation if authorized. This directly impacts capital gains, as IAEA sales close much faster, reducing post-death appreciation. At Los Angeles’s approximate 5% annual appreciation rate, a $900,000 home gains roughly $3,750 per month in taxable value.

Los Angeles County Superior Court probate proceedings often take 12-18 months. Orange and San Diego counties may be slightly faster. Every month of delay matters from a tax standpoint, making an efficient sale crucial.

Deductible Costs That Reduce Your Capital Gains

The taxable gain is not simply the sale price minus the stepped-up basis. California heirs can deduct qualified selling costs from the sale proceeds. These typically include:

  • Real estate agent commissions
  • Transfer and documentary stamp taxes
  • Title insurance premiums
  • Escrow and attorney fees related to the sale
  • Costs of required repairs made specifically to facilitate the sale

For example, a $900,000 sale with an $850,000 stepped-up basis and $27,000 in selling costs results in a taxable gain of only $23,000. Properly accounting for these deductions is essential.

California Inherited Home Sale: Tax Impact Timeline

Month 0

Date of Death

Stepped-up basis is established at the home’s Fair Market Value (FMV). The process to appoint a California Probate Referee is initiated.

Month 1-2

Estate Administration

The Probate Referee completes the official appraisal. The court appoints a personal representative, and an IAEA election is made if applicable to speed up the sale.

Month 3-6

Sale Process (With The Probate Realtor)

Multiple offers are received within 24 hours. The property is sold “as-is,” which eliminates repair delays. A court confirmation is not needed for sales under IAEA.

Month 4-7

Close of Escrow & Tax Calculation

Capital gains are calculated: Sale Price minus Stepped-Up Basis minus Selling Costs. The quick sale minimizes post-inheritance appreciation.

Financial Impact: An efficient sale avoids $11,250 – $22,500 in additional taxable appreciation on a typical $900K Los Angeles home.
Month 6-18

Without a Probate Specialist (Traditional Timeline)

A longer timeline allows the property’s value to appreciate further past the stepped-up basis, creating more taxable gain. Each additional month of delay adds ~$3,750 in appreciation.

Tax Liability Risk: Each month of delay can create an additional ~$1,125 in CA state tax liability.

Practical Steps to Sell and Minimize Capital Gains

Executing the sale efficiently is what protects your financial outcome. An experienced California probate real estate specialist helps heirs accomplish these critical steps:

  • Complete the Probate Referee appraisal promptly. This establishes your stepped-up basis and is a crucial first step.
  • Determine if IAEA applies. Independent administration authority can cut months off the sale timeline, directly reducing your tax exposure.
  • Sell as-is to qualified buyers immediately. Spending money on renovations rarely produces a dollar-for-dollar return and adds months to the timeline, increasing taxable gain.
  • Account for all deductible selling costs. Work with a tax professional and your probate agent to ensure every eligible deduction is captured.

Executors often feel pressure to renovate an inherited property before selling. In most cases, that money doesn’t come back at closing—and it doesn’t reduce your capital gains exposure. Our buyers purchase properties exactly as they are, which means heirs keep more of the stepped-up basis advantage rather than spending it on pre-sale improvements.” — Dallas Seely

Frequently Asked Questions
What is the stepped-up basis for inherited property in California?

The stepped-up basis resets an inherited property’s cost basis to its fair market value on the date of the original owner’s death, under IRC § 1014. This means an heir only owes capital gains taxes on appreciation that occurred after they inherited the property, not on decades of prior appreciation. In California, the official stepped-up basis is typically established by a court-appointed Probate Referee under California Probate Code §§ 8800-8980.

Does California have a double step-up in basis for community property?

Yes. Because California is a community property state, when a married couple holds property as community property and one spouse dies, both the deceased spouse’s half and the surviving spouse’s half receive a stepped-up basis. This “double step-up” can completely eliminate capital gains even on highly appreciated California properties, and it is a significant advantage not available in non-community property states.

How does the California probate timeline affect capital gains taxes on an inherited home?

Every month between the date of death and the sale closing allows additional appreciation to accumulate above the stepped-up basis, creating additional taxable gain. Los Angeles County probate proceedings typically take 12-18 months, which at LA’s approximate 5% annual appreciation rate can add roughly $3,750 per month in taxable gain on a $900,000 property. Using the Independent Administration of Estates Act (IAEA) under California Probate Code §§ 10400-10592, heirs may be able to sell without court confirmation and close significantly faster, directly reducing tax exposure.
