1031 Exchange in Los Angeles: What Investment Property Sellers Need to Know
Selling a rental or investment property in Los Angeles? Here's how a 1031 exchange defers capital gains, California's FTB 3840 rule, and the 45-day deadline you can't miss.
What Is a 1031 Exchange and How Does It Work in Los Angeles?
A 1031 exchange allows Los Angeles investment property owners to defer federal capital gains taxes and California's 13.3% state tax by selling one investment property and reinvesting the proceeds into another like-kind property. You have 45 calendar days to identify your replacement property and 180 days total to close on it. A qualified intermediary must hold your proceeds the entire time. You cannot touch the money. California adds its own layer: even if you exchange into a property in another state, the California Franchise Tax Board tracks your deferred gain using Form FTB 3840 and taxes it when you eventually sell without another exchange.

If you own a rental home, a single-family investment property, or a small income-producing building in Los Angeles, selling carries serious tax exposure.
At a $3 million sale price on a property you purchased years ago, you could owe federal long-term capital gains tax, the 3.8% net investment income tax, and California state tax at rates up to 13.3%. On a $1.8 million gain, that bill can exceed $650,000.
A 1031 exchange is one of the few legal tools that defers that entire tax bill. Here's how it works in Los Angeles, what California adds to the equation, and the planning move most sellers miss until it's too late.
What Qualifies for a 1031 Exchange
Only investment and business property qualifies. That's the first thing to understand.
Your primary residence does not qualify. The home you live in falls under a completely different section of the tax code (Section 121, which provides a $250,000 or $500,000 exclusion on gain for primary residence sellers). This is about the investment side: rental homes, income-producing properties, vacant land held for investment, and small commercial buildings.
In Los Angeles, a significant number of single-family homes have been converted to rentals over the years, and many have appreciated dramatically. If you've been renting out a home in Silver Lake, Beverly Grove, Studio City, or the Hollywood Hills for the past decade, you're sitting on a substantial capital gain. A 1031 exchange is worth understanding before you list.
How the Exchange Works
The mechanics are straightforward, but the deadlines are unforgiving.
When you accept an offer and open escrow, you must already have a qualified intermediary (QI) in place. A QI is a licensed third party who holds your sale proceeds after closing. You never receive the money directly. The moment the funds hit your personal bank account, the exchange fails and you owe full taxes on the gain.
After your property closes:
- You have 45 calendar days to identify your replacement property in writing to the QI. Not 45 business days. Weekends and holidays count. If day 45 falls on a Sunday, your identification is due that Sunday.
- You have 180 calendar days from the sale to close on the replacement property.
The 45-day and 180-day clocks run at the same time. Both start the day your relinquished property closes.
Under the standard "Three Property Rule," you can identify up to three potential replacement properties and close on any of them. If you identify more, additional rules apply. Miss the deadline entirely, and you owe the taxes with no extension available except in the case of a federally declared disaster. Following the 2025 Southern California wildfires, the IRS did grant exchange deadline extensions for affected taxpayers. Outside of a qualifying disaster, the clock does not stop.
The California Catch
Here's where Los Angeles sellers often get surprised.
California does not block a 1031 exchange, but it tracks the deferred gain with Form FTB 3840. You file this form in the year of the exchange and every year after, until you eventually sell the replacement property in a taxable transaction.
If your replacement property is located outside California, the Franchise Tax Board continues tracking the deferred gain annually. The year you sell that out-of-state property without completing another exchange, California taxes its portion of the original gain.
This does not make a 1031 exchange a bad strategy for sellers planning to leave California. It means you need to understand what you're deferring and that the California liability follows you until you either complete another exchange or pass the property to heirs (who receive a stepped-up basis at death, potentially eliminating the deferred gain entirely).
If you exchange into another California property, the FTB tracking still applies, but the tax liability stays within the state's reach when you eventually sell.
What You're Deferring in Dollars
To put this in concrete terms: say you purchased a rental home in Los Feliz for $800,000 in 2014, and you're selling today for $2.8 million. After depreciation recapture, cost basis adjustments, and sale costs, your taxable gain might be around $1.8 million.
Federal long-term capital gains at 20%: $360,000. Net investment income tax at 3.8%: $68,400. California at 13.3%: $239,400.
Total tax liability: approximately $668,000.
A properly structured 1031 exchange defers all of that as long as you reinvest the full proceeds into qualifying replacement property. That's $668,000 that keeps working for you instead of going to tax authorities in the year you sell.
Keep in mind that sellers above the Measure ULA thresholds also owe the LA mansion tax on top of capital gains. For investment property sellers above $5.15M (the approximate current threshold), the combination of Measure ULA and capital gains taxes makes exchange planning especially important when you're modeling your true net proceeds.
The DST Option for Tired Landlords
Not every LA investor wants to manage another rental property. If you're done with tenants and maintenance calls, a Delaware Statutory Trust (DST) may be worth considering.
A DST is a fractional ownership structure where your exchange proceeds go into a professionally managed commercial or residential property portfolio. The IRS treats DST interests as like-kind real property for 1031 purposes, so the exchange qualifies. You receive passive income distributions and no management responsibilities.
DSTs are not for everyone. They're illiquid, carry their own risk profile, and are typically structured with minimum investment thresholds. But for an LA investor who wants to exit active ownership while deferring a large capital gain, the DST is a legitimate tool to understand before you dismiss it.
California does still recognize 1031 exchanges into DSTs as of 2026. Given the legislative environment in Sacramento, verify this with your tax advisor before you act.
The Planning Move Most Sellers Miss
The single most common 1031 exchange mistake in Los Angeles: the seller doesn't appoint a qualified intermediary before closing.
You cannot designate a QI after the sale closes. The exchange agreement must be in place before you receive any proceeds. Some sellers don't think about a 1031 until they're already in escrow. Others don't think about it until after closing. By then, the option is gone and the tax bill is locked in.
If you're selling a rental or investment property in Los Angeles and a 1031 exchange is even a possibility, have that conversation with a QI and a tax advisor before you accept an offer. The QI needs to be ready before you close, not after.
This is especially relevant if you hold the property through a living trust or LLC. The entity structure affects how the QI and exchange agreements are signed, and getting that wrong can disqualify the exchange. If you hold property in a trust, understanding how trust sales work is part of the planning.
How This Affects Your Sale Strategy
Running a 1031 exchange does not change how your property is marketed or priced. You're still selling at market value. The exchange happens after the sale, outside the buyer's view.
But knowing you're planning an exchange does affect your timeline. If you're selling a $4 million rental in Sherman Oaks and need to close on a $4.5 million replacement property within 180 days, you need to start identifying replacement options before you list the relinquished property, not after. The 45-day identification window moves quickly in a thin inventory market.
Working with an agent who understands exchange timelines matters here. The timing of your sale and the structure of any contingencies can align with, or work against, your exchange strategy.
The Step-Up in Basis Alternative
For investors who plan to hold long-term, it's worth knowing that heirs receive a stepped-up basis at death. The embedded capital gain in an appreciated Los Angeles property can be eliminated entirely if the property passes through an estate rather than being sold during the owner's lifetime.
A 1031 exchange defers. A stepped-up basis eliminates. These are two different tools for two different situations, and your tax advisor can help you model which approach fits your goals.
Frequently Asked Questions
Can I do a 1031 exchange on my primary residence in Los Angeles?
No. A 1031 exchange applies only to investment and business property. Your primary residence is covered by Section 121 of the tax code, which provides a $250,000 gain exclusion for single filers or $500,000 for married couples filing jointly. If you converted a former primary residence into a rental, a partial 1031 exchange may be available depending on how long you rented it and how long you lived in it before the conversion. A tax advisor can run that analysis for your specific timeline.
What happens if I miss the 45-day identification deadline?
The exchange fails. You owe capital gains taxes on the full sale as if no exchange was attempted. There are no extensions for missed deadlines except in the case of a federally declared disaster. The IRS did grant deadline extensions for taxpayers affected by the 2025 Southern California wildfires, but absent a qualifying event, the clock does not pause for any reason.
Does California tax 1031 exchanges?
California allows 1031 exchanges but does not fully conform to federal treatment. The state tracks your deferred gain using Form FTB 3840, filed annually after the exchange. If you exchange out of a California property into a replacement in another state, California still taxes its portion of the original gain the year you sell the replacement property in a taxable transaction. The 1031 exchange defers the California tax, it does not eliminate it.
How much of the proceeds must I reinvest to defer the full capital gain?
To defer all capital gains, you must reinvest 100% of the net proceeds from your sale and take on equal or greater debt on the replacement property. If you reinvest less, the difference, called "boot," is taxable in the year of the exchange. For example, if your relinquished property netted $2 million and you only invest $1.6 million in the replacement, the $400,000 difference is subject to capital gains tax.
Can I exchange into a Delaware Statutory Trust (DST)?
Yes. The IRS recognizes DST interests as like-kind real property for 1031 exchange purposes. A DST lets you exchange into a passive, professionally managed investment property portfolio without taking on new landlord responsibilities. This is a useful option for Los Angeles investors who want to exit active management while keeping the tax deferral intact. DST investments are illiquid and are typically offered through licensed broker-dealers, so vet the sponsor and the deal carefully.
A 1031 exchange is one of the most effective strategies available to Los Angeles investment property owners. The key is starting early: a qualified intermediary must be in place before your sale closes, your replacement property identification window is shorter than most sellers expect, and California's FTB 3840 rule follows you across state lines until the gain is eventually recognized.
