What Is a 1031 Exchange and Why It Still Matters in 2026
The biggest 1031 exchange news heading into mid-2026 is refreshingly simple: Section 1031 survived every legislative challenge thrown at it over the past two years. Real estate investors can still defer federal capital gains taxes by reinvesting sale proceeds into qualifying replacement property through a properly structured like-kind exchange. That single fact preserves one of the most powerful wealth-building tools in the entire tax code.
Named after Section 1031 of the Internal Revenue Code, this provision allows you to sell investment or business-use real estate and roll the gain into a new property without triggering an immediate tax bill. The gain does not disappear. It transfers to the replacement property through a reduced cost basis, deferring the tax obligation until you eventually sell without executing another exchange.
For a practical example, consider an investor who purchased a rental property for $400,000 and sells it for $700,000. The $300,000 capital gain would typically generate a federal tax bill exceeding $60,000 at the 20% long-term rate — before state taxes or depreciation recapture enter the equation. A properly executed tax-deferred real estate swap lets that investor reinvest the full $700,000, compounding returns on capital that would otherwise go to the IRS.
How the One Big Beautiful Bill Act Affects Like-Kind Exchanges
Section 1031 Survives: No Cap on Deferred Gains
The One Big Beautiful Bill Act (OBBBA), signed into law on July 4, 2025, as Public Law 119-21, was the most significant tax legislation since the 2017 Tax Cuts and Jobs Act. Earlier drafts of the bill proposed a $500,000 annual cap on deferred gains — a provision that would have fundamentally weakened Section 1031 for mid-size and large investors. That cap was rejected before final passage, thanks largely to lobbying by the Federation of Exchange Accommodators.
The result is clear: there is no new limit on the value of property eligible for a like-kind exchange, no restriction on the amount of gain that can be deferred, and no sunset provision threatening future repeal. Investors can continue executing these transactions at any dollar level, provided they satisfy every existing IRS requirement.
100% Bonus Depreciation Restored Permanently
The OBBBA also permanently restored 100% bonus depreciation for qualifying property placed in service after January 19, 2025. Before this legislation, bonus depreciation was scheduled to decline to 40% in 2025, drop to 20% in 2026, and phase out entirely afterward. This restoration creates a powerful synergy with Section 1031 that we will examine in the triple-stack strategy section below.
Capital gains tax rates remain unchanged as well. The favorable spread between long-term capital gains rates (0%, 15%, or 20% depending on income) and ordinary income rates (up to 37%) continues to make tax-deferred exchanges financially compelling for investors across all brackets.
Core Rules Every Investor Must Follow
The 45-Day Identification Window
From the moment your relinquished property closes, a strict 45-calendar-day clock begins. Within that window, you must deliver a written, signed identification of potential replacement properties to your qualified intermediary or another party involved in the exchange. Vague descriptions will not satisfy the IRS. Each identified property needs a specific street address or legal description.
Three identification rules govern how many properties you can name. The Three-Property Rule allows up to three properties regardless of their combined value. The 200% Rule permits any number of properties as long as their total fair market value does not exceed twice the value of the relinquished property. The 95% Rule lets you identify unlimited properties at any value, but you must acquire at least 95% of the total identified value.
The 180-Day Closing Deadline and Tax Return Trap
You have 180 calendar days from the sale of your relinquished property to close on the replacement property. No extensions exist. However, a critical nuance shortens this window for many investors: your actual deadline is the earlier of 180 days or the due date for your tax return for that year.
This trap catches investors who sell property late in the calendar year. If you sold a property on November 1, 2025, your 180-day window extends to April 30, 2026. But your 2025 tax return is due April 15, 2026 — fifteen days sooner. Without filing a tax extension using IRS Form 4868, your exchange deadline defaults to April 15, cutting your timeline short and potentially destroying the entire transaction.
Like-Kind Property Requirements After TCJA
Since the Tax Cuts and Jobs Act took effect in 2018, Section 1031 applies exclusively to real property. Equipment, vehicles, livestock, artwork, and all other forms of personal property are permanently excluded. Within real estate, the “like-kind” standard is interpreted broadly. You can exchange a single-family rental for a commercial warehouse, raw land for an apartment complex, or a retail building for a farm — so long as both properties are held for investment or productive business use.
Primary residences do not qualify. True vacation homes used solely for personal enjoyment are also excluded. Property held primarily for resale — such as a fix-and-flip project — falls outside the provision because it is classified as dealer property, not investment real estate.
The Qualified Intermediary Requirement
Every deferred exchange requires a qualified intermediary (QI), sometimes called an exchange accommodator. The QI is a neutral third party who holds your sale proceeds in a segregated, insured account and facilitates the transfer of both properties. You cannot serve as your own intermediary, and your attorney, accountant, real estate agent, or broker is disqualified from acting in this role if they have served you in any of those capacities within the preceding two years.
One absolute rule governs the relationship between you and the exchange funds: you cannot touch the money. If sale proceeds are payable to you at any point — even briefly — the IRS treats that as constructive receipt of income. The exchange fails immediately, and the full capital gain becomes taxable. This is not a technicality that auditors overlook. It is among the most aggressively enforced provisions in the entire Section 1031 framework.
Before signing an exchange agreement, verify that your QI is bonded and insured, holds exchange funds in accounts fully separate from operating capital, and has a documented track record handling transactions of similar size and complexity.
Understanding Boot, Basis, and Hidden Tax Triggers
Boot is the term for any value received in an exchange that does not qualify as like-kind property. It triggers an immediate tax obligation. Boot takes two common forms: cash boot, where you receive leftover exchange funds because the replacement property costs less than the relinquished property, and mortgage boot, where the debt on the replacement property is lower than the debt retired on the relinquished property.
Consider a scenario. You sell a rental property for $500,000 with a $200,000 mortgage. Your net equity is $300,000. You purchase a replacement for $450,000 with a $200,000 mortgage, using $250,000 from the exchange. The remaining $50,000 is boot and becomes taxable income in the year of the exchange. To avoid boot entirely, your replacement property must be equal to or greater in both total value and total debt compared to the relinquished property. This is the fundamental “trade up or across” principle.
Your tax basis in the replacement property also carries forward from the relinquished property, reduced by any deferred gain. This lower basis affects future depreciation deductions and determines the taxable gain if you eventually sell without performing another exchange.
Types of 1031 Exchanges: Deferred, Simultaneous, Reverse, and Improvement
Deferred Exchange (Standard)
Approximately 95% of all Section 1031 transactions follow the deferred exchange structure. You sell your relinquished property first, the QI holds the proceeds, you identify replacement property within 45 days, and you close on the replacement within 180 days. The gap between sale and purchase is what makes a QI essential — without one, you would constructively receive the funds and disqualify the exchange.
Reverse Exchange
A reverse exchange flips the standard order. You acquire the replacement property before selling the relinquished property. An Exchange Accommodation Titleholder (EAT) takes title to the new property and “parks” it for up to 180 days while you complete the sale of your existing asset. Reverse exchanges are growing increasingly popular in competitive 2026 markets where desirable replacement properties attract multiple offers and require fast closing timelines.
The tradeoff is complexity and cost. Reverse exchanges require more legal coordination, higher intermediary fees, and meticulous documentation to satisfy IRS Revenue Procedure 2000-37.
Improvement (Build-to-Suit) Exchange
An improvement exchange allows you to use tax-deferred dollars to renovate or construct improvements on the replacement property before taking title. The EAT holds title while construction occurs, and you receive the property — with improvements completed — within the 180-day window. This structure lets investors increase the value of replacement property using capital that would otherwise go to taxes, making it a particularly effective tool for value-add real estate strategies.
Delaware Statutory Trusts as Replacement Property
Delaware Statutory Trusts (DSTs) have emerged as one of the fastest-growing replacement property vehicles for Section 1031 exchanges. A DST is a legal entity that holds title to investment real estate and sells fractional interests to investors. Those fractional interests qualify as like-kind property under IRS Revenue Ruling 2004-86, making DSTs a legitimate option for completing an exchange.
The appeal is straightforward. DSTs eliminate active property management. They provide access to institutional-quality assets — large multifamily complexes, medical office buildings, industrial warehouses — that individual investors could not typically acquire alone. Minimum investments generally start around $100,000, and diversification across multiple properties or geographic markets becomes possible within a single exchange.
DSTs also carry meaningful downsides. You sacrifice control over property decisions, face illiquidity since DST interests cannot be sold on an open market, and absorb sponsor fees that can reach 10–15% of the investment. Due diligence on the DST sponsor’s track record, fee structure, and underlying asset quality is essential before committing exchange funds to this path.
The 2026 Triple-Stack: Combining 1031, Bonus Depreciation, and Opportunity Zones
Three legislative developments have converged to create what tax strategists are calling the “triple-stack” — a rare alignment of provisions that may never occur again in this configuration. The OBBBA preserved Section 1031 without caps, permanently restored 100% bonus depreciation, and renewed the Opportunity Zone program with new zone designations beginning in mid-2026.
Here is how the strategy works in practice. An investor sells a commercial property with a $900,000 capital gain. Rather than paying $180,000 or more in federal taxes, the investor executes a like-kind exchange into a replacement property acquired after January 19, 2025. That replacement property qualifies for 100% bonus depreciation through a cost segregation study, generating substantial first-year deductions that shelter other income. Simultaneously, the investor directs a portion of separate capital gains into a Qualified Opportunity Fund, deferring those gains until December 31, 2026, with the potential for tax-free appreciation on the Opportunity Zone investment if held for at least ten years.
Each strategy is powerful independently. Stacked together, they allow investors to defer gains on one property, accelerate depreciation on another, and potentially eliminate taxes on a third — all within the boundaries of current law. Executing this combination requires coordination among a tax advisor, qualified intermediary, cost segregation specialist, and Opportunity Zone fund manager.
State-Level Developments: California AB 1611 and Reporting Requirements
Federal rules are only half the compliance picture. California’s Assembly Bill 1611, effective January 1, 2026, eliminates Section 1031 eligibility for corporations owning 50 or more single-family homes. The law targets institutional homebuyers and is designed to recapture an estimated $1.2 billion in deferred state tax revenue annually. Individual taxpayers and small LLCs with portfolios below the 50-property threshold remain fully eligible for like-kind exchange treatment in California.
Several other states impose ongoing reporting obligations for exchanges where the replacement property is located outside the state. California, Massachusetts, Montana, and Oregon track out-of-state exchanges and may enforce clawback provisions if the deferred gain is eventually recognized through a taxable sale. Failure to file required annual state reports can create significant complications years later, even if the federal exchange was executed flawlessly.
Investors operating across state lines should confirm reporting requirements in every jurisdiction where they hold or sell property. State-level compliance is an area where many otherwise sophisticated investors expose themselves to unnecessary audit risk.
Five Compliance Mistakes That Kill an Exchange
Touching the proceeds. Any direct or constructive receipt of exchange funds before acquiring replacement property disqualifies the entire transaction. The QI must hold all funds from the moment of sale through the moment of purchase. There are no exceptions.
Missing the 45-day deadline. This window is absolute. If you fail to deliver a written, signed identification of replacement properties within 45 calendar days, the exchange is dead. Late identification — even by a single day — cannot be cured.
Ignoring the tax return due date. Investors who sell property in the final quarter of the year frequently overlook the rule that the exchange deadline is the earlier of 180 days or their tax return due date. Filing a tax extension is a simple step that preserves the full 180-day window.
Changing the taxpayer entity. The same taxpayer who sells the relinquished property must acquire the replacement property. If you sell as an individual but attempt to acquire through a newly formed LLC, or sell through a partnership and acquire individually, the IRS will treat these as different taxpayers and disqualify the exchange. Entity structure must remain consistent across both legs of the transaction.
Using a disqualified intermediary. Your attorney, CPA, real estate broker, or any agent who has acted for you within the past two years cannot serve as your qualified intermediary. Using a disqualified person invalidates the exchange from day one, regardless of how perfectly every other requirement was met.
Filing Form 8824: Reporting Your Exchange to the IRS
IRS Form 8824 must be filed for every completed like-kind exchange, even if the transaction produced zero taxable income. The form documents the structure and timing of the exchange, identifies both properties, and calculates any recognized gain, deferred gain, and adjusted basis in the replacement property.
The reporting year is determined by when the relinquished property was sold, not when the replacement property was acquired. If you sold in 2025 and closed on the replacement in early 2026, Form 8824 belongs with your 2025 tax return. Information reported on the form must align precisely with closing statements and exchange documents. Inconsistent data is one of the most common triggers for IRS follow-up inquiries.
Maintain thorough records of the exchange agreement, QI correspondence, identification letters, closing statements for both properties, and all wire transfer confirmations. These documents support every figure on Form 8824 and become your primary defense if the IRS questions the transaction.
Frequently Asked Questions
What is the latest 1031 exchange news for 2026?
The OBBBA, signed in July 2025, preserved Section 1031 without imposing any new caps or restrictions on deferred gains. Combined with permanently restored 100% bonus depreciation and renewed Opportunity Zones, 2026 offers a rare convergence of tax-deferral strategies for real estate investors.
Can I exchange a rental property for raw land?
Yes. The like-kind standard for real property is broadly defined. Any real estate held for investment or business use can be exchanged for any other real estate held for the same purpose. A single-family rental, commercial building, farmland, and vacant lot are all eligible, provided neither property is a personal residence or held primarily for resale.
What happens if I miss the 45-day identification deadline?
The exchange fails with no remedy. The full capital gain from your relinquished property becomes taxable in the year of sale. The IRS grants no extensions to this deadline under any circumstances, making it one of the most critical dates in the entire process.
Does California’s AB 1611 affect individual real estate investors?
No. The law applies exclusively to corporations owning 50 or more single-family homes. Individual investors, small LLCs, and entities below the 50-property threshold retain full access to Section 1031 benefits for California transactions.
Do I need to file Form 8824 even if my exchange produced no taxable income?
Yes. The IRS requires this form for every completed like-kind exchange regardless of outcome. It documents the transaction structure, deferred gain, and adjusted basis in your replacement property. Failure to file can trigger audit inquiries.
