Selling investment real estate triggers capital gains tax, depreciation recapture under IRC §1250, and potentially the 3.8% Net Investment Income Tax. The combined federal bite can approach 40% or more for high earners. A properly executed IRC §1031 like-kind exchange eliminates that tax entirely in the year of sale, deferring it into the replacement property's adjusted basis. But the exchange must follow rigid rules. Miss the 45-day identification deadline by a single day and the entire transaction becomes a taxable sale.
What Qualifies as Like-Kind Property Under IRC §1031?
Since January 1, 2018, IRC §1031 applies exclusively to real property. The Tax Cuts and Jobs Act permanently eliminated like-kind exchange treatment for personal property, equipment, vehicles, aircraft, artwork, and intangible assets. Any property that was exchanged under §1031 before 2018 under transitional rules is now fully subject to recapture.
For real property, "like-kind" is interpreted broadly. The IRS looks at the nature or character of the property, not its quality or grade. These exchanges all qualify:
The property must be held for investment or productive use in a trade or business, not held primarily for sale. A "fix-and-flip" property sold by a dealer does not qualify, regardless of how long it was held. See our tax planning services for guidance on structuring your real estate holdings correctly from the outset.
What Are the Critical Deadlines in a 1031 Exchange?
The two deadlines are absolute. Neither can be extended for weekends, holidays, natural disasters (absent a presidentially declared major disaster area), or any other reason.
1031 Exchange Timeline
Deadlines- Day 0: Relinquished property closes, exchange period begins
- Day 45: Written identification of replacement property due
- Day 180: Replacement property acquisition must close
- Return due date: Replaces Day 180 if earlier (e.g., April 15 for calendar-year filers who sold in Oct through Dec)
The 45-day identification rule requires the taxpayer to identify replacement property in a signed written document delivered to the Qualified Intermediary or seller. Oral identifications do not count. Three alternative identification rules apply:
- Three-Property Rule: Identify up to 3 properties of any value; you must acquire at least one.
- 200% Rule: Identify any number of properties, provided their combined fair market value does not exceed 200% of the relinquished property's FMV.
- 95% Exception: Identify any number of properties at any value, but you must acquire at least 95% of the total identified FMV.
The 180-day deadline is the earlier of (a) 180 calendar days after the relinquished property transfer, or (b) the due date (including extensions) of the taxpayer's return for the year the relinquished property was sold. Taxpayers who sell in the fourth quarter and do not file Form 4868 may hit the April 15 return deadline before the 180-day window closes. Filing an extension to October 15 resolves this conflict.
What Is a Qualified Intermediary and Why Is It Required?
A Qualified Intermediary (QI) is a mandatory structural element of a §1031 exchange. If the taxpayer has actual or constructive receipt of the sale proceeds at any point, the exchange fails, regardless of intent. The QI holds the proceeds from the relinquished property sale and uses them to fund the replacement property acquisition.
The IRS imposes a 2-year look-back independence requirement: the QI cannot have been the taxpayer's attorney, accountant, investment banker, real estate agent, or employee within the two years preceding the exchange. Using a regular business attorney as QI is one of the most common disqualifying errors.
QI Fund Segregation and Bankruptcy Risk
CautionThe QI holds your exchange funds, often for the full 180 days. If the QI becomes insolvent or files for bankruptcy during that period, your funds may be at risk. Select a QI that maintains fidelity bond coverage, segregates each client's funds in separate accounts, and requires dual signatures for disbursement. The QI industry is unregulated at the federal level; several states require QI bonding or licensing.
How Is Boot Taxed in a Partial Exchange?
Boot is any non-like-kind property, cash, or net debt relief received in an exchange. Under IRC §1031(b), gain is recognized to the extent of boot received. Losses are never recognized in a §1031 exchange.
Recognized gain = Lesser of: (1) total realized gain, or (2) total boot received
Common sources of boot:
- Cash received at closing
- Mortgage relief: if the replaced debt is greater than the assumed debt on the replacement property, the net debt relief is treated as cash boot
- Non-like-kind personal property received (e.g., furniture included in the sale of a commercial property)
To execute a fully tax-deferred exchange, the investor must: (1) reinvest all cash proceeds, and (2) acquire replacement property with equal or greater debt than was relieved on the relinquished property, or make up any debt shortfall with additional cash equity.
How Is the Replacement Property's Tax Basis Calculated?
This is the most frequently misunderstood aspect of §1031. The replacement property's adjusted basis is not its purchase price. It is the carryover basis of the relinquished property, adjusted for boot and recognized gain.
Example: A taxpayer sells a rental property with an adjusted basis of $400,000 (after accumulated depreciation) for $900,000. They exchange into a $900,000 replacement property with no boot. Their basis in the replacement property is $400,000, not $900,000. The $500,000 in deferred gain and the accumulated depreciation history transfer to the replacement property.
This deferred basis means future depreciation deductions on the replacement property are calculated on $400,000 (allocated to depreciable components), not $900,000. The deferred gain and recapture do not disappear. They follow the property until a future taxable disposition or death (when stepped-up basis rules under IRC §1014 may eliminate the deferred gain).
For individual investors and business owners holding appreciated property, understanding this basis carryover is essential to modeling the long-term tax picture accurately.
What Is a Reverse Exchange and When Does It Make Sense?
A standard forward exchange requires selling the relinquished property before acquiring the replacement. A reverse exchange, structured under IRS Revenue Procedure 2000-37, allows the taxpayer to acquire the replacement property first, then sell the relinquished property within 180 days.
Reverse exchanges are used when:
- The replacement property is available immediately and may not remain so
- A targeted replacement property is identified before the current property is listed
- Financing requires the new property to close before the old one sells
Rev. Proc. 2000-37 Safe Harbor Requirements
Reverse ExchangeThe Qualified Exchange Accommodation Agreement (QEAA) must be executed within 5 business days of the accommodation titleholder (an affiliate of the QI) taking title to the replacement property. The same 45-day identification and 180-day completion rules apply in reverse sequence: the relinquished property must be identified within 45 days and sold within 180 days of the replacement property acquisition. Reverse exchanges are significantly more complex and expensive than forward exchanges; anticipate higher QI fees and greater IRS scrutiny.
How Do Partnerships and LLCs Handle 1031 Exchanges?
A §1031 exchange must be conducted by the same taxpayer who owned the relinquished property. Partnerships and LLCs present a structural challenge: individual partners often want different exit strategies. Some want to exchange, others want to cash out. The entity itself would need to unanimously agree to exchange the entire property.
The "drop-and-swap" is the standard solution:
Drop-and-Swap for LLC Exits
Before selling the property, the LLC distributes fractional ownership interests (tenants in common, or TIC) to individual members. Each member then independently sells their TIC interest and executes their own §1031 exchange into a replacement property of their choosing. The IRS's step-transaction doctrine requires that the TIC ownership be held for a meaningful period (typically two or more years) before the sale. Executing the drop and the sale within weeks of each other creates high audit risk. Contact a tax advisor to structure the timing before beginning the distribution.
Delaware Statutory Trust (DST) as Replacement Property
A Delaware Statutory Trust holding investment real estate qualifies as like-kind replacement property under Revenue Ruling 2004-86. DSTs allow investors to acquire fractional interests in institutional-grade properties (net-lease portfolios, multifamily, industrial) without active management obligations. DST interests cannot be used as relinquished property in a subsequent §1031 exchange (they must ultimately be sold in a taxable transaction or converted to a different structure), but they satisfy the 45-day and 180-day deadlines efficiently when the investor cannot identify suitable direct replacement properties in time.
What Must Be Reported on Form 8824?
Form 8824 (Like-Kind Exchanges) must be filed with the federal return for the tax year in which the relinquished property was transferred, even if zero gain is recognized. Key lines:
- Lines 1–7: Property descriptions, transfer dates, identification dates, acquisition dates
- Lines 12–18: FMV of properties, liabilities assumed, cash boot calculations
- Line 23: Total realized gain on the exchange
- Line 24: Recognized gain (equals boot received, if any)
- Line 25: Basis of the replacement property (carryover basis, as computed above)
Line 25 carries forward to the depreciation schedule for the replacement property. Using the wrong basis figure (a common error when preparers treat the replacement property's purchase price as its depreciable basis) creates phantom depreciation deductions that will generate recapture on the next sale.
If boot was received, recognized gain flows to Schedule D (capital gain) or Form 4797 (business property), with Section 1250 unrecaptured depreciation taxed at a maximum 25% rate. Review our tax planning services or individual tax services for full exchange return preparation.
