California 1031 Exchanges and DSTs: Taxes, Rules, and Property Review

By Jerry Baker

A California property owner can use a qualifying 1031 exchange to defer gain and buy replacement real estate in California or another U.S. state. California adds its own reporting and withholding issues, especially when the replacement property is outside the state. This guide explains those issues before you choose a direct purchase or a Delaware statutory trust, known as a DST.

Separate the sale, the exchange, and the investment

There are three decisions here. First, is selling your current property a good choice? Second, does an exchange fit your tax situation? Third, is the replacement investment worth owning? A useful answer to one question does not settle the other two.

You might own an apartment building that has grown in value while repairs have become more demanding. An exchange could help preserve capital for another investment. But buying an unsuitable property just to avoid a current tax bill can leave you with a larger problem. I want to understand both the money and the work you want your real estate to do.

Start with the income you need and cash you must keep available. List the work you want to stop doing and risks you can accept. Then add your expected sale price, debt payoff, and adjusted tax basis. Those numbers have different jobs. Sale proceeds tell us what cash may be available; basis helps your CPA calculate gain.

The federal rules still come first

Section 1031 generally covers qualifying real property held for investment or business use. Property held mainly for sale is excluded. Real estate can be like-kind even when its use or quality differs, but U.S. real property is not like-kind to foreign real property. A personal home is a different starting point from an investment rental. [1]

In a standard delayed exchange, arrange the qualified intermediary, or QI, before closing. The arrangement must restrict your access to the proceeds. You generally identify replacement property in writing within 45 days. You must acquire it by the earlier of 180 days or the tax return due date, including extensions. The periods overlap. These are legal deadlines, not a guarantee that banks or closing teams will work until midnight. [2]

My practical preference is to review the options before the sale makes the schedule urgent. Give the QI a clear list, confirm delivery, and keep proof. The written identification must satisfy the rules; a casual email to someone uninvolved in the exchange is not a reliable plan.

Buying outside California does not erase California gain

California requires Form FTB 3840 when qualifying California property is exchanged for out-of-state property. The form tracks California-source deferred gain. It generally continues annually until that gain is recognized, even when the owner otherwise has no California return to file. The 2025 instructions state that residency does not remove this requirement. [3]

That matters when the conversation begins with, “I want to get out of California.” You may be changing where the real estate sits, where you live, or both. Those are separate facts. A new address on a deed should not be treated as proof that a prior state tax obligation disappeared.

Ask your CPA to keep a schedule linking the property sold, each replacement interest, the gain allocated to it, and later exchanges. Keep that schedule with closing statements and tax returns. If you divide an exchange among several properties, good records become even more useful. A future sale should not require reconstructing years of transactions from memory.

For a hypothetical example, consider an owner who sells a California rental and buys two qualifying out-of-state interests. The exchange may defer gain, but the adviser still needs to track the California portion across both replacements. This example makes no assumption about the gain amount, basis allocation, or the eventual tax bill.

Handle California withholding before escrow closes

California real estate withholding is a prepayment toward tax, not the final calculation of tax owed. Form 593 addresses exemptions and exchange treatment. A qualifying deferred exchange can be exempt at the initial transfer, while cash received or a failed exchange can change withholding obligations. The specific facts and form instructions control. [4]

Put the escrow officer, QI, and CPA in contact early. Ask who will complete the form, who will sign, and what happens if you receive money back. A plan that says only “this is a 1031” leaves too much unsaid.

Also ask which closing charges can be paid from exchange funds without an unwanted tax result. Do not assume that every line on a closing statement is an allowable exchange expense. Loan items, prorations, deposits, and transaction costs may need different treatment. The federal reporting instructions address cash, liabilities, and exchange expenses; your adviser should apply them to the actual statement. [5]

Do not carry an old property-tax bill into a new budget

A California building held for many years may have a tax assessment far below its current value. Buying another building can change that expense. The Board of Equalization explains that a change in ownership generally causes reassessment to current fair market value unless an exclusion applies. Federal income-tax deferral does not itself settle the separate property-tax question. [6]

When reviewing a replacement, ask for the current bill and a written estimate of the bill after the proposed transaction. Identify the assessor, taxing areas, special assessments, and any assumptions about exclusions. For entity or trust structures, have the legal team explain what the ownership changes mean.

Suppose a hypothetical property produces $200,000 before property taxes, insurance, and financing. Suppose the model uses an old tax bill that is $25,000 below the expected new bill. That error reduces the money left for other costs. The building did not become less attractive overnight; the original budget was incomplete.

Compare the money each property earns after costs. An old owner's personal cash flow may use a different expense base than a sponsor's forecast. The ownership structure, purchase price, and expense basis may differ.

For apartments, review the exact local rules

California's statewide Tenant Protection Act and local rent rules can affect residential operations. Exemptions and notice requirements depend on the property and ownership. The Department of Real Estate's 2026 landlord-tenant guide also describes local rules that can offer greater tenant protections. A broad statement about “California rent control” is not a complete review. [7]

For an apartment acquisition, I would ask counsel to identify which rules cover each building. Then I would compare that answer with the rent-growth plan. Does the forecast depend on increases that are allowed? Does it assume quick tenant turnover? Are renovations optional, required for habitability, or part of a change in use?

A renovation budget should account for the time a unit may be unavailable, lawful notice procedures, and the cost of the work. Ask the manager to show comparable completed projects, rather than treating a finish schedule as proof that residents will pay the projected rent.

Review collections as well as occupancy. A unit may be leased while rent is overdue. Ask for aging reports, concessions, and actual money collected. Those records help distinguish strong demand from a full building that still produces weak cash flow.

Treat insurance and physical hazards as separate files

California property review should include location-specific fire and seismic work. CAL FIRE's hazard maps are useful screening tools. They should not be treated as a property inspection, an insurance quote, or a forecast of a specific loss. [8]

For earthquake exposure, the California Geological Survey's EQ Zapp shows mapped fault rupture, liquefaction, and landslide zones. It also identifies areas where hazards have not yet been evaluated. An unmapped parcel is not a professional finding that no hazard exists. [9]

I would want the sponsor's engineer and insurance adviser to connect those findings to the building. What is its construction type? What work is recommended? What is funded? Which losses are covered, excluded, or subject to large deductibles?

The state's commercial insurance guide distinguishes property coverage from other business protections and explains the importance of exclusions and coverage terms. Review the actual policy schedule, not just a certificate or a line labeled “insurance” in a budget. [10]

Ask whether a quoted premium is binding, when the policy renews, and how a sharp increase would affect distributions. Check business-income coverage and the period it would support. A building can survive a loss while access restrictions or repairs interrupt rent for months.

A state is too large to be your market analysis

“California real estate” includes many different customer bases, building types, and local rules. I would not use one statewide story to explain an apartment near a university, a warehouse serving a port, and a suburban medical office.

Define the property's actual competitive area. For housing, that may mean nearby units at similar rents and quality. For industrial space, truck access, power, loading, and tenant requirements may matter more than a city label. For a medical property, review the lease, operator, and whether the layout can serve another user.

A useful comparison lists properties, dates, concessions, and differences. Ask whether quoted rents are asking rents or signed lease rents. Ask whether a nearby development is merely proposed, approved, financed, or under construction. Those stages do not carry the same weight.

I would also examine the customer behind the income. What kind of household can afford the apartment's total monthly cost? What pays the commercial tenant's bills? Which employers, industries, or contracts create shared exposure? These questions are often more useful than a market ranking with a large headline.

Compare a direct purchase with a DST on purpose

A direct property purchase can preserve control over leasing, financing, repairs, and sale timing. That control also carries work. A DST can shift daily management to others, but the investor accepts the governing documents and has limited control over major decisions.

The IRS recognized 1031 treatment for the specific DST structure described in Revenue Ruling 2004-86. The ruling includes restrictions on the trustee's powers. It is not blanket approval of all trusts or a promise that any DST will meet your exchange needs. [11]

Read what the trust can do when the business plan needs to change. Who may replace a tenant? What financing actions are permitted? Could the investment change structure under stress, and how might that affect future exchanges? Request the offering's own legal and tax analysis.

Private placements can be hard to sell, involve limited disclosure, and carry a risk of losing the investment. Eligibility also depends on the offering. The SEC urges investors to understand these risks before committing money. [12]

If access to your cash is important, decide how much liquidity to keep outside the exchange investment. A planned hold is not a promise to pay you back on that date.

Use one comparison sheet for California and out-of-state options

I would put the same facts beside every option. That helps us test claims about an unfamiliar market. It also keeps a familiar street from getting a free pass.

Then test the result under a less favorable case. Lower revenue, higher insurance, and a weaker exit price should not be buried in separate worksheets. Show their combined effect on cash available and the equity that may come back.

Keep equity, debt, and tax basis on different lines

Imagine a California property sells for $2 million with an $800,000 loan payoff. Ignoring all closing costs, the cash proceeds would be $1.2 million. That does not mean the taxable gain is $1.2 million. Investing only that cash also may not fully replace the value sold.

For federal reporting, debt relief, replacement debt, cash paid, expenses, and basis all enter the calculation. Have your CPA and QI establish the target using the actual transaction. [5]

For investment comparison, a hypothetical $300,000 equity allocation at 50% investor-level LTV represents $600,000 of value and $300,000 of debt before other adjustments. At 0% LTV, the same equity represents $300,000 of value. Neither is automatically better. The first has more debt exposure; the second replaces less value with the same cash.

Use the offering's stated investor allocation, including how it handles acquisition costs and fees. Do not substitute a lender's appraisal LTV if it uses a different denominator. A tidy calculation is only helpful when it measures the right thing.

Build a file that will survive the next exchange

Keep the original purchase statement, improvements, depreciation schedules, sale documents, identification, QI agreement, replacement closing records, and federal and state reporting. Add the California gain-tracking schedule when applicable.

For a DST, save the final documents for the interest you actually purchased. A preliminary brochure may describe a different allocation or earlier projection. Keep sponsor tax reports and notices of material changes together so the next adviser can follow what happened.

Assign the annual filing task to a named person. Ask what records they need and when you should send them. If you change CPAs, include the exchange history in the handoff. This is administrative work, but it protects the usefulness of the planning you did at the beginning.

Questions I would bring to the first meeting

• Why are you selling, and what would make the replacement better for you?
• How much dependable spending money do you need outside the investment?
• Do you want California exposure, out-of-state exposure, or a mix for a stated reason?
• What are the CPA's gain estimate and exchange targets?
• Who is tracking the 45-day identification and the closing deadline?
• Which local expenses or legal limits could undermine the property plan?
• What would cause us to reject an option even if its tax treatment works?

That last question deserves an answer before a deadline is close. A tax benefit is valuable, but it cannot make a weak property, unsuitable debt, or an unwanted long-term commitment fit your life.

Frequently asked questions

Can I exchange California rental property for a DST in another state?

Potentially, if both the DST interest and the transaction qualify. The real estate does not have to remain in California. Review the offering's tax structure, federal exchange requirements, and California gain-reporting obligations with your advisers. [1] [3] [11]

Does moving out of California eliminate the deferred gain?

Do not assume that it does. Form FTB 3840 tracks California-source gain when California property is exchanged for out-of-state property. The filing requirement can continue for a nonresident. Your CPA should review later dispositions and your individual facts. [3]

Does a 1031 exchange preserve my old property-tax assessment?

Not automatically. Income-tax exchange treatment and property-tax reassessment are separate questions. Have the assessor or qualified tax counsel review the ownership change and any available exclusion, and budget using the expected assessment after purchase. [6]

Is a California DST safer because I know the market?

Familiarity can help you ask better questions, but it does not remove tenant, financing, operating, liquidity, or loss risk. Review the exact property and documents. A location you recognize can still be paired with assumptions or debt that do not fit you.

Should I choose a state with no individual income tax?

State taxes are one part of the comparison. Your residence, the source of income, prior deferred gain, ownership structure, and property expenses all matter. Ask your CPA to compare the total picture before using a state's tax label as the deciding factor.

What should I do before listing my property?

Gather basis and debt records, discuss the potential sale with your CPA, and speak with a QI about exchange mechanics. Then define the income, liquidity, control, and risk you want from the replacement. Early planning gives you time to reject unsuitable choices.

Educational information, not an offer or a personal tax, legal, or investment recommendation. Examples are hypothetical and omit stated adjustments. Tax treatment depends on your facts and current law. Review your transaction with your CPA, attorney, and qualified intermediary. Real estate investments can lose value and may be illiquid.
