1031 Exchanges: A Practical Overview for Investors

A Section 1031 exchange can be a powerful planning tool for real estate owners who want to reposition investment property without immediately recognizing taxable gain. Used well, it can create flexibility: moving from one property type to another, consolidating or diversifying holdings, shifting geography, or reducing management burden. Used casually, it can create missed deadlines, unexpected taxable “boot,” state filing issues, and limited exit options.

This overview explains the core rules and common replacement-property paths, including traditional real property exchanges, Delaware statutory trusts, and UPREIT / Section 721 structures.

What Is a 1031 Exchange?

A 1031 exchange allows a taxpayer to defer gain when exchanging real property held for productive use in a trade or business or for investment, so long as the replacement property is also like-kind real property held for business or investment use. The IRS notes that, after the Tax Cuts and Jobs Act, Section 1031 applies only to real property, not personal or intangible property.

That “deferral” point matters. A 1031 exchange does not erase gain. Instead, the deferred gain generally carries into the replacement property through basis rules and may become taxable later if the replacement property is sold in a taxable transaction.

To qualify, taxpayers must pay close attention to both the nature of the property and the exchange mechanics. Real property held primarily for sale, such as dealer property or inventory, does not qualify. If the taxpayer receives cash or non-like-kind property, commonly called “boot,” gain may be recognized to the extent of that money or other property received.

In a deferred exchange, timing is critical. The taxpayer generally has 45 days from the transfer of the relinquished property to identify replacement property, and the replacement property must be received by the earlier of 180 days after transfer or the due date, including extensions, for the taxpayer’s return for that year.

The identification rules are also technical. A taxpayer may generally identify up to three replacement properties without regard to fair market value, or identify more properties if the aggregate value does not exceed 200% of the relinquished property’s value, subject to additional rules.

Option 1: Traditional 1031 Exchange Into Real Property

The most familiar structure is an exchange from one investment or business real property into another. For example, a taxpayer may exchange a rental home for a commercial building, vacant land for an apartment building, or one investment property for multiple replacement properties.

This path may provide the most control. The taxpayer owns the replacement property directly or through an entity structure (i.e. a single member LLC), chooses the property, controls financing, and manages the long-term exit strategy. It may also preserve the ability to continue future 1031 exchanges if the taxpayer later sells the replacement property.

The tradeoff is operational responsibility. Direct ownership often comes with financing requirements, leasing decisions, repairs, local tax filings, insurance, and market concentration. For investors who are comfortable managing real estate, this may be appropriate. For those seeking a more passive structure, other options may be worth evaluating.

Option 2: 1031 Exchange Into a Delaware Statutory Trust

A Delaware statutory trust, or DST, is often used as replacement property in a 1031 exchange. In Revenue Ruling 2004-86, the IRS held that a qualifying DST described in the ruling was classified as a trust for federal tax purposes and that a taxpayer could exchange real property for an interest in that DST without recognizing gain under Section 1031, assuming the other Section 1031 requirements were met.

In practical terms, a DST allows an investor to own a proportional interest in real estate rather than directly owning and managing an entire property. The investor generally reports their share of rental real estate activity, often on Schedule E, rather than receiving a partnership K-1. DSTs may also offer access to larger institutional-style properties, potential diversification, and a more passive ownership experience.

DSTs can be useful as a primary replacement option or as backup identified property. DSTs are can be used to address:

financing obstacles (DSTs typically have pre-arranged financing in place),
provide backup property identification (if a primary property falls through a DST can be acquired to preserve the exchange)
fill exchange value gaps (a fractional ownership can absorb any “boot” to defer the entire gain),
and reduce property management burden (DSTs are a complete passive investment)

Although it is important to consider the limitations with a DST. DST investments are typically illiquid and may be locked up for a projected holding period, often six to ten years depending on the offering. Investors also give up direct control over property decisions. Many DSTs own real estate outside California or across multiple states, which may create additional state income tax filing requirements.

A DST may also provide future flexibility. Upon disposition, a taxpayer may be able to complete another 1031 exchange from a DST into another DST, into directly owned real property, or, if the structure allows, into an UPREIT / Section 721 transaction.

Option 3: UPREIT / Section 721 Exchange

An UPREIT structure is related to 1031 planning but is not the same thing as a traditional 1031 exchange. Under Section 721, no gain or loss is generally recognized when property is contributed to a partnership in exchange for a partnership interest.

In an UPREIT transaction, the investor typically contributes real estate or certain real estate interests to an operating partnership connected to a REIT and receives operating partnership units, often called OP units. This may continue tax deferral at the contribution stage, but it changes the investor’s exit path. There are no exchange deadlines like those of a 1031 exchange which may offer the investor more flexibility on timing. Like a DST the management of the OP units is completely passive.

The key tradeoff: investors can generally exchange in, but not back out through a 1031 exchange. Section 1031 excludes partnership interests from like-kind exchange treatment, so OP units generally do not function like directly owned replacement real estate for future 1031 purposes.

Tax is typically triggered when OP units are later converted, redeemed, or otherwise disposed of for cash or REIT shares, depending on the structure. During the holding period, compliance may feel more familiar because ongoing activity is generally reported as partnership activity, with the investor receiving a Schedule K-1. However, investors may still face multi-state filing obligations depending on the REIT operating partnership’s footprint and income sourcing.

California Clawback and Form 3840

California adds another layer for taxpayers exchanging California real property for out-of-state replacement property. California requires taxpayers who exchange California property for out-of-state like-kind property in a 1031 exchange to file Form FTB 3840 annually. The form reports and tracks California-source deferred gain or loss.

This is often called California’s 1031 “clawback” rule. California’s position is that the source of gain from California property is preserved even if recognition is deferred federally and the replacement property is located elsewhere. Form 3840 is generally required for the year of the exchange and each subsequent year until the California-source deferred gain or loss is recognized.

Final Thoughts

A 1031 exchange is not just a tax deferral technique. It is a strategic decision about liquidity, control, compliance, geography, estate planning, risk tolerance, and future flexibility. Traditional real property may offer control. DSTs may offer passive exposure and exchange continuity. UPREIT / Section 721 transactions may offer simplified ownership and REIT diversification, but often at the cost of future 1031 optionality. Because the rules are technical and the consequences can be significant, taxpayers should evaluate each exchange with tax, legal, investment, and cash-flow advisors before committing to a structure.
