The California 1031 Exchange Guide (2026)

AUTHOR: Anthony Alosi

The TL;DR Version

Because California conforms to IRC section 1031, a successful California 1031 exchange generally follows federal guidelines. What makes California unique is its state income tax, clawback rule, and real estate withholding. Spotting these early is critical.

What Is a 1031 Exchange in California?

A 1031 exchange in California lets real estate investors sell property held for investment or business purposes and reinvest the proceeds into a “like-kind” replacement property, potentially deferring recognition of capital gain. The state conforms to IRC section 1031, meaning any properly-structured exchange may defer both federal and California income tax.

A 1031 exchange in California follows the same 45- and 180-day windows, uses a Qualified Intermediary the same way, and defers gain the same way. Where this shifts slightly is with California’s unique reporting and tax-collecting layers. This can complicate exchanges if not fully understood.

If you’re considering a California 1031 exchange, this guide covers the key information you need to know.

What Are the 1031 Exchange Rules in California?

There are two layers to consider with California’s 1031 exchange rules and subtleties. The first layer is the federal framework that applies to any 1031 exchange across the U.S. Second is the state’s specific mechanics that play a role in exchanges to and from California. An exchange will need to satisfy both of these layers to ultimately succeed.

The Federal 1031 Exchange Layer

The same rules that govern 1031 exchanges anywhere in the U.S. also apply in California. Your exchange will need to satisfy:

1. The Like-Kind Requirement: The relinquished and replacement properties must both be real property held for investment or business use. Since the Tax Cuts and Jobs Act took effect in 2018, personal property no longer qualifies.

2. The 45-day Identification Window: Once you close on the relinquished property, you have up to 45 days to identify replacement properties in writing.

3. The 180-day Exchange Window: The purchase of a replacement property must close by the earlier of 180 days or the applicable tax-return due date, including extensions.

4. The Use of a Qualified Intermediary: To preserve full deferral, investors generally should not receive the exchange proceeds – directly or indirectly. As a result, your chosen Qualified Intermediary holds the funds and documents the exchange to preserve capital gains deferral by preventing the constructive receipt of those funds.

5. The Filing of Form 8824: Finally, you will need to report your exchange to the IRS by filing Form 8824.

The California 1031 Exchange Layer

When compared to many other states in the U.S., California diverges slightly from the standard process.

1. The Clawback Rule: When you exchange California-based property for like-kind property in another state, California retains the right to tax the California-source deferred gain when the replacement property is eventually sold. This is done through clawback.

2. FTB Form 3840: Any investor who exchanges California property for out-of-state property generally must file this form annually until the deferred gain is recognized. This allows the state to keep the clawback gain on its books.

3. Real Estate Withholding: The sale of real property in California is subject to withholding at close. Certain 1031 exchanges that qualify may have this exempt, but it is best to assume the transaction will need to satisfy this as well.

While the above responsibilities primarily fall to a CPA, tax advisor or attorney, it is still important to understand how they can affect the ultimate 1031 exchange in California.

California’s Specific 1031 Exchange Mechanics, Explained

California’s 1031 exchange rules differentiate the state’s process from a no-income-tax state, for example. A tax advisor will help navigate through these responsibilities, however, knowing them can help you find the right deal at the right time.

1. California’s Clawback Rule

Exchanging investment property for a like-kind property outside of California does not eliminate California tax on the deferred California-source gain. The state reserves the right to tax the deferred gain when the replacement property is eventually sold, regardless of where the investor lives.

This is where some investors get tripped up. California’s clawback attaches to deferred gains rather than the taxpayer’s residency. You can sell a California rental, exchange into an out-of-state property, move to a no-income-tax state, and still owe California tax on the original California-sourced gain when you finally cash out. Leaving California alone is not enough.

This will matter most when considering where to exchange to, especially if the investor is simply looking to “get out of California taxes.” You and your advisors should discuss it in greater detail, but this helps avoid setting a wrong expectation early in the exchange process.

2. FTB Form 3840 Annual Reporting

California tracks the deferred gain through a filing. If you close on California property and exchange to out-of-state replacement property, you generally must file FTB Form 3840 for the exchange year and then every year afterward, generally until the California-sourced deferred gain is recognized.

• This is an annual obligation. The filing requirement continues year after year, which surprises investors who assume the paperwork ended when the exchange closed.

• It can apply even if no other California returns are due. An investor who has fully relocated out of state and owes California nothing else may still need to file Form 3840.

• Skipping the submission has serious consequences. When the form isn't filed, the FTB may estimate the investor’s income and assess tax, penalties, and interest on that basis.

When considering a move out of California, know that the above obligations exist so there are no surprises later in the 1031 exchange.

3. California Real Estate Withholding and Form 593

A sale of California real property is generally subject to the state’s withholding rules. A qualifying 1031 exchange may be fully or partially exempt from withholding when properly certified on Form 593.

4. The State’s Higher Tax Rate

California taxes capital gains at ordinary-income rates, with a maximum individual rate that can reach 13.3%. This won’t change how a 1031 exchange in the state operates, but it is important to keep in mind. A deferred gain that would carry a modest state tax bill elsewhere can represent a materially larger number in California. The table below shows how this varies depending on where the replacement property is located.

What Happens When You 1031 Exchange Out of California?

Let’s say you're set on a replacement property outside of California. What happens then? Common examples include exchanges from California into markets like:

1. CA to TX: Texas is one out-of-state market California investors may consider. No state income tax on the Texas side, lower cost of entry, and strong demand for multifamily and industrial.

2. CA to NV: Nevada may appeal because of its proximity and no individual state income tax. The familiar West Coast geography can make Nevada a common landing spot, particularly around Las Vegas and Reno.

3. CA to AZ: Phoenix-area growth and relative affordability draw California investors looking for yield without leaving the region.

4. CA to FL: Florida may appeal to investors looking further, also attracted by no individual state income tax and a large investor market.

Three Misconceptions Investors May Have About Exchanging Out of California

1. Moving to Texas won’t erase California’s clawback: This is a crucial one. If an investor exchanges to Texas, they might assume the move eliminates California tax on the deferred gain. However, the clawback attaches to the deferred gain. If an investor’s preference is to move out of the state, they should consult with a tax advisor early so they can iron this out.

2. The Form 3840 obligation continues every year, even with no California return otherwise due. If an investor fully relocates, they may assume that no further California filings are required. However, the Form 3840 keeps them on the hook.

3. Withholding applies at the California sale even when the exchange fully defers. The relinquished property is real property in California. As a result, it runs through California's withholding process at closing regardless of where the replacement sits. A qualifying exchange is exempted only when it's properly certified on Form 593.

California Property Taxes and 1031 Exchanges

Another important topic to consider is that 1031 exchanges and property taxes operate on separate paths in California. A 1031 exchange may defer income-tax recognition, but it generally does not preserve the relinquished property’s Proposition 13 base-year value.

Under Proposition 13, passed in 1978, a California replacement property acquired in an exchange typically receives a new base-year value set at its purchase price. The relinquished property’s older, lower valuation will not be carried forward. For someone trading up from a long-held property with a favorable Prop 13 base, that can mean a meaningfully higher property tax bill on the replacement.

Proposition 19’s base-year-value transfer provisions generally apply to qualifying principal residences, not investment and property used in a typical 1031 exchange.

A favorable Prop 13 base doesn't travel with the investor through an exchange, so the replacement property should be underwritten with a reassessed tax bill in mind.

California Markets to Know for 1031 Exchanges

From metro Los Angeles to the state’s “Inland Empire”, several California markets illustrate the range of property types investors may encounter in a 1031 exchange:

1. Los Angeles: Multifamily, retail, and infill industrial properties dominate in the LA market. The region's rent stabilization and tenant-protection rules shape how investors underwrite multifamily, and many exchange to reposition out of heavily regulated rental stock or to consolidate scattered holdings. Industrial and last-mile logistics near the ports also continue to draw replacement-property demand.

2. San Francisco Bay Area: The Bay Area’s average home prices place it well within the top 10 most expensive real estate markets in the U.S. Multifamily and mixed-use properties are common investment categories in the region, with investors often exchanging into more management-friendly assets or out-of-state markets for yield. Local rent regulation and a shifting office picture push investors toward diversification, and the size of the gains involved raises the stakes on getting the exchange timing right.

3. San Diego: With opportunities in multifamily and commercial properties, San Diego sees steady 1031 demand. The military and biotech presence also supports investors looking for investment properties. Its position near the border makes it a common entry point for investors building a Southern California portfolio.

4. Orange County and the Inland Empire: Orange County skews toward higher-value multifamily and commercial, where investors often trade appreciated coastal assets. The Inland Empire, by contrast, is one of the country's most active industrial and logistics markets, and warehouse and distribution products are a frequent replacement-property target. A potential path for 1031 exchanges is to relinquish multifamily property in Orange County for Inland Empire industrial properties.

5. Sacramento: The state’s capital city attracts 1031 exchanges from the pricier coastal cities. Investors exchange into multifamily and commercial here for different pricing and investment characteristics while staying inside California, which keeps the replacement property on the same side of the claw-back and property tax rules.

6. Central Valley: As the agricultural core of the state, 1031 exchanges in California’s Central Valley typically involve farmland, orchards, and vineyards alongside commercial and industrial property. Agricultural exchanges have their own nuances, including water rights, so it’s important to plan those early.

Worked Examples of 1031 Exchanges in California

While these are not tax calculations for specific deals, and the outcome of your exchange depends on your unique financial situation, here are five examples of what a 1031 exchange in California could look like. These are illustrative examples only and should not be used as financial advice.

1. A Straightforward CA-to-CA Delayed Exchange

An investor sells a Los Angeles rental for $1.2 million and, in a properly structured delayed exchange, acquires a qualifying $1.2 million replacement apartment building in Sacramento within the 45-day and 180-day windows. Assuming the exchange meets Section 1031 requirements, the gain may be deferred for both federal and California income tax.

The Sacramento property generally receives a new Prop 13 base-year value at its purchase price. The favorable base on the long-held LA property likely won’t carry forward.

2. The CA to TX Path

An investor sells a California property for $1.5 million, carrying roughly $600,000 of California-sourced deferred gain, and exchanges into a Texas multifamily property.

This is where California stays in the picture. The investor generally must file FTB Form 3840 for the exchange year and every year afterward, tracking that $600,000 of deferred California-sourced gain, even after relocating to Texas. If the investor later sells the Texas property in a taxable transaction, California's claw-back reaches that original $600,000 of California-source gain, regardless of Texas residency.

3. A Partial Exchange With Boot

An investor sells a California property for $900,000 but reinvests only $750,000 into the replacement, taking $150,000 in cash out of the transaction. That $150,000 may constitute boot, with gain generally recognized up to the amount of boot in the year received.

Because the relinquished property is California real property, the sale runs through California's withholding process, and while a fully deferred exchange may be exempted when certified on Form 593, the non-deferred boot portion may be subject to withholding. The remaining reinvested gain may still be deferred, so a partial exchange doesn't lose the deferral entirely; it just makes the boot piece currently taxable.

4. Bay Area Multifamily Consolidation

An investor owns two smaller Bay Area rental properties, worth $800,000 and $1.1 million, and wants to consolidate into a single larger $2 million replacement building. While this works within the 1031 exchange parameters, the investor is relinquishing two properties and acquiring one, and the identification and timing windows apply across the transaction.

The 45-day identification and 180-day exchange clocks are generally measured from the closing of the first relinquished property, which can compress the timeline if the two sales aren't closely coordinated. An investor consolidating this way benefits from lining up the sales and the replacement identification early.

5. A Central Valley Agricultural Exchange

An investor sells Central Valley farmland for $2.5 million and exchanges into a commercial building. Because like-kind treatment for real property is broad, farmland and commercial real estate can generally be exchanged for one another when both are held for investment or business use.

In this scenario, the investor would need to understand any water rights associated with the farmland may factor into value and, depending on how they're held and characterized, into what counts as real property in the exchange. That's a fact-specific question for the investor’s tax counsel, not something to resolve at the listing table.

Choosing a Qualified Intermediary in California

California is among the states that directly regulate exchange facilitators. Most states leave the QI role unregulated, which puts the burden on the investor to vet a facilitator. In California, the state's Financial Code (Section 51000 et seq.) sets baseline requirements a facilitator must meet to hold exchange funds for California investors.

The law covers three areas:

1. Bonding and Deposits: Facilitators are generally required to maintain a fidelity bond, a deposit, or equivalent security tied to the funds they handle.

2. Coverage of Errors or Omissions: Facilitators are expected to carry E&O insurance covering acts and omissions in the course of their work.

3. Standards for Handling Funds: The law addresses how exchange funds are invested and held, including prudent-investor-style standards meant to protect the client's money while it's in the facilitator's hands.

The specific statutory requirements should be reviewed based on the facilitator and transaction involved. But California has set a floor, and a QI operating here should be able to speak to how they meet each of these obligations.

When choosing a QI, you should consider: the bond or security backing the funds, the E&O coverage in place, how and where exchange funds are held, and the facilitator's track record.

At First American Exchange Company, we hold exchange funds in segregated, FDIC-insured accounts and can provide information about the safeguards and coverage supporting those funds. Fund-security practices, insurance coverage and financial controls are among the factors investors may consider when choosing a Qualified Intermediary.

FAQs

Does California recognize 1031 exchanges?

Yes. California conforms to IRC Section 1031, so a properly structured exchange of real property held for investment or business use may defer both federal and California income tax on the gain, provided the transaction meets the statutory requirements.

What is the California clawback rule?

Clawback lets California tax the California-sourced deferred gain when an investor exchanges California property for out-of-state property and later sells that replacement in a taxable transaction.

Do I have to file Form 3840 every year?

Generally, it is an ongoing obligation. Investors who exchange California property for out-of-state replacement property must typically file FTB Form 3840 for the exchange year and every year afterward, until the deferred gain is recognized or otherwise eliminated.

Can I do a 1031 exchange from California to another state?

Yes. California property can generally be exchanged for out-of-state replacement property under Section 1031, deferring gain when the requirements are met.

Does moving out of California avoid the clawback?

In most cases, no. The clawback obligation follows the deferred gain, not the taxpayer's residency. An investor can relocate to a no-income-tax state after exchanging out of California and still owe California tax on the original California-sourced gain.

Is withholding required when I sell California property in a 1031 exchange?

Sales of California real property are generally subject to state withholding at closing. A qualifying exchange may be exempt from withholding when properly certified on FTB Form 593. If the exchange produces boot above the applicable threshold or fails to qualify, withholding may apply.

What happens if I never sell the replacement property?

If an investor holds the replacement property until death, the deferred gain may remain unrecognized during their lifetime. Inherited property basis rules may then affect the tax treatment for heirs, depending on the circumstances. This is a fact-specific estate planning matter for the investor’s tax advisor and legal counsel.

Do California 1031 exchanges defer state taxes too?

Yes. Because California conforms to Section 1031, a properly structured exchange may defer California income tax on the gain alongside federal tax. If the replacement property sits outside of the state, however, clawback and other provisions may kick in.

What is FTB Publication 1031?

FTB Publication 1031 covers California residency and part-year residency guidelines for income tax. Despite the number, it is not about 1031 exchanges.

Are Qualified Intermediaries regulated in California?

Yes. California is one of the few states that regulates exchange facilitators directly. The state's Financial Code (Section 51000 et seq.) generally addresses bonding or security, errors-and-omissions coverage, and standards for handling exchange funds.
