Qualified Intermediary: The Independent Party That Makes Section 1031 Work
A qualified intermediary (QI) is the independent third party that holds your sale proceeds, prepares the exchange paperwork, and acquires the replacement property on your behalf so you can defer capital gains tax under Internal Revenue Code Section 1031. Without a qualified intermediary, an exchange of investment real estate collapses into a taxable sale the moment you take “actual or constructive receipt” of the cash, as defined under Treasury Regulation 1.1031(k)-1(f). The QI exists because the IRS needed a workable safe harbor: a real-world way for sellers to swap properties through a chain of arm’s-length transactions without ever touching the proceeds themselves. Get the QI selection right and your tax-deferred swap closes on schedule; get it wrong and the entire deferral evaporates, frequently with penalties stacked on top.
This article covers the IRC Section 1031 mechanics, the strict 45-day identification and 180-day exchange timeline, the four safe-harbor rules under Treas. Reg. 1.1031(k)-1(g), how to vet a QI, the like-kind property requirement, the boot rules that trigger partial recognition, title-holding pitfalls, and a fully worked example showing the actual cash flow on a $1 million relinquished property rolling into a $1.5 million replacement. We will also walk through five mistakes that recur in Tax Court decisions and the bonding gaps that have cost taxpayers tens of millions when intermediaries went bankrupt or absconded with funds.

IRC Section 1031 Foundation: From 1921 to TCJA
The like-kind exchange concept is older than most of the modern tax code. Congress enacted the first version in 1921 as Section 202(c) of the Revenue Act of 1921 (Pub. L. 67-98), reasoning that a taxpayer who swapped one piece of business property for another had not converted appreciation into spendable cash. The rule was renumbered to Section 112(b)(1) in 1928 and then to Section 1031 when the Internal Revenue Code was reorganized in 1954. The current statute at 26 U.S.C. 1031 retains the original “no gain or loss shall be recognized” formulation from 1921.
The single most consequential change in a century came on December 22, 2017, when President Trump signed the Tax Cuts and Jobs Act (TCJA), Pub. L. 115-97. Section 13303 narrowed Section 1031 to “real property held for productive use in a trade or business or for investment,” effective for exchanges completed after December 31, 2017. Personal property exchanges (aircraft, equipment, livestock, artwork, collectibles, franchise rights, vehicle fleets) were eliminated entirely. Joint Committee on Taxation report JCX-67-17 estimated the narrowing would raise $31 billion over the 2018-2027 budget window.
Section 1031 is now exclusively a real estate tool. The Treasury Department issued final regulations on November 23, 2020 (T.D. 9935, 85 Fed. Reg. 76837) defining “real property” for 1031 purposes using a state-law-plus-federal-list approach. A fixture is real property if it is permanently attached and would be real property under the law of the state where it is located, with a federal carve-in list that explicitly includes leasehold interests of 30 years or more, easements, mineral rights, water rights, air rights, and certain inherently permanent structures. The final 2020 regulations resolved years of ambiguity over whether items like wind turbines, solar panels, and HVAC systems traveled with the real property or had to be carved out as personal-property boot.
Eligibility Rules and Qualifying Property
Three eligibility tests apply. First, both properties must be real property under the 2020 final regulations. Second, both must be held for productive use in a trade or business or for investment, which excludes a primary residence, a second home used predominantly for personal enjoyment, and inventory held for sale (dealer property). Rev. Proc. 2008-16 created a safe harbor for vacation homes: the dwelling qualifies if owned at least 24 months, rented at fair market value at least 14 days in each of the two preceding 12-month periods, with personal use not exceeding the greater of 14 days or 10 percent of rental days.
Third, the properties must be like-kind. For real property the standard is famously broad: raw land qualifies with a hotel, an apartment building with a strip-mall pad site, and a 30-year leasehold with a fee-simple interest. Treasury Regulation 1.1031(a)-1(b) explicitly states one kind or class of real property may be exchanged for another. What does not qualify across the line: U.S. real property cannot be exchanged for foreign real property (IRC 1031(h)), and vice versa, although either category can be exchanged internally.
The “held for” test is determined at the time of the exchange. In Goolsby v. Commissioner, T.C. Memo. 2010-64, the Tax Court denied 1031 treatment to a couple who moved into their replacement property within two months of acquisition. The unofficial industry guideline is a two-year hold plus contemporaneous documentation of rental intent: an appraisal with rental valuation, an MLS listing, a property management agreement, and rental income on Schedule E. If 1031 treatment is denied, the installment sale alternative can spread gain over multiple years.
Partnerships create a special trap. An undivided partnership interest is not real property for 1031 purposes. The partnership itself can exchange, but a partner who wants to cash out while others exchange faces the “drop and swap” problem, where the partnership distributes a tenant-in-common interest to the exiting partner before the sale. The IRS has attacked drop-and-swap structures on substance-over-form grounds, and the safest pattern under Bolker v. Commissioner, 760 F.2d 1039 (9th Cir. 1985) requires the partnership distribution to occur far enough in advance that the exiting partner can show separate investment intent.
The 45-Day Identification Period
The first hard deadline starts ticking the day you close on the relinquished sale. Under IRC 1031(a)(3)(A), you have exactly 45 calendar days from closing to identify potential replacement properties in writing. Saturdays, Sundays, and federal holidays count, with one narrow exception: if day 45 itself falls on a weekend or federal holiday, the deadline rolls forward to the next business day under IRC 7503.
Identification must be unambiguous. Treasury Regulation 1.1031(k)-1(c)(3) requires identification by legal description, street address, or tax parcel number. “An office building in Denver” fails. The identification must be in a written document signed by the taxpayer and delivered to the QI or another party that is not the taxpayer or a disqualified person. Email is acceptable if delivery can be evidenced, and most major QIs now operate secure portals with timestamped uploads.
You may identify up to three replacement properties without value limit (the “three-property rule”), or any number of properties whose aggregate fair market value does not exceed 200 percent of the relinquished property’s value (the “200-percent rule”), or any number of any value provided you acquire 95 percent of the aggregate identified (the “95-percent rule”). Sophisticated investors using the three-property rule typically identify three properties of escalating quality so that backups exist within the window.
The identification is revocable in writing at any time before midnight of day 45, following the same delivery and signature rules. After day 45 the list freezes. This is the single most common point of failure in 1031 exchanges. Industry data from the Federation of Exchange Accommodators (FEA), the QI trade association, suggests roughly 3 to 5 percent of started exchanges fail because the taxpayer cannot get a viable replacement under contract during the window in a tight market.
The 180-Day Exchange Period
The second hard deadline is the 180-day exchange period under IRC 1031(a)(3)(B). You have 180 calendar days from the relinquished closing, or the due date (including extensions) of your tax return for the year of the relinquished sale, whichever is earlier. The “whichever is earlier” clause is the gotcha. Close on November 1, 2026 and your 180-day window technically runs to April 30, 2027, but your 2026 return is due April 15, 2027. Unless you file Form 4868, your effective deadline is April 15.
The fix is mechanical: file Form 4868 before April 15 to extend your return to October 15, which preserves the full 180 days. Practitioners file the 4868 routinely for any exchange that crosses a tax-year boundary.
The 180-day clock cannot be paused for force majeure, contract delays, lender problems, or title disputes. The IRS does grant disaster-related extensions under IRC 7508A when FEMA declares a federally designated disaster area. The 2017 Hurricane Harvey relief (Notice 2017-56), the 2020 COVID-19 relief (Notice 2020-23), and the 2024-2025 California wildfire and Florida hurricane disaster declarations all extended both deadlines for affected taxpayers, typically by 120 days.
Closing on day 180 means closing in the legal sense: title transfer recorded or held in escrow with no remaining buyer-side contingencies. A “closing” that consists of signing documents while waiting for a lender wire on day 181 has been treated as a failed exchange in private letter rulings. Industry practice is to close no later than day 175 to leave room for wire delays and recording backlogs.
Qualified Intermediary Requirements Under the Safe Harbor
The QI safe harbor lives at Treasury Regulation 1.1031(k)-1(g)(4), one of four safe harbors that allow a taxpayer to avoid being treated as having actual or constructive receipt of sale proceeds. The other three (security or guarantee arrangements, qualified escrow accounts and trusts, and growth-factor interest arrangements) are used less frequently because the QI structure is operationally simpler.
To qualify under 1.1031(k)-1(g)(4), the QI must satisfy four conditions. First, the intermediary cannot be a “disqualified person” under 1.1031(k)-1(k), which excludes anyone who has acted as the taxpayer’s agent within the two years preceding the exchange, including the taxpayer’s employee, attorney, accountant, investment banker, real estate agent, or broker. The two-year lookback is rigid. In Blangiardo v. Commissioner, T.C. Memo. 2014-110, the Tax Court denied 1031 treatment because the intermediary was the taxpayer’s longtime accountant. If your CPA also wants to be your QI, the answer is no. The disqualified-person trap is laid out in the statute itself at 26 U.S.C. 1031(f) and amplified by the Treasury safe-harbor mechanics codified at Treas. Reg. 1.1031(k)-1(g)(4).
Second, the taxpayer and the QI must enter into a written exchange agreement that expressly limits the taxpayer’s rights to receive, pledge, borrow, or otherwise obtain the benefits of the exchange funds. The standard FEA model exchange agreement includes these limitations as boilerplate, and FEA members are also bound by the trade association’s FEA Code of Ethics covering segregation, disclosure, and conflicts. Funds must be segregated to prevent commingling with the QI’s own assets, which after the 2008-2009 QI bankruptcies (LandAmerica, 1031 Tax Group) has become a state-licensing requirement in 11 states.
Third, the QI must acquire the relinquished property from the taxpayer and transfer it to the buyer, and acquire the replacement property from the seller and transfer it to the taxpayer. In practice, this is accomplished through assignment of the taxpayer’s rights under the purchase contracts to the QI, with written notice to the other parties before the relevant closings. The QI does not actually hold legal title; title flows directly from seller to buyer in the relinquished leg, and from replacement seller to taxpayer in the replacement leg.
Fourth, the QI cannot be related to the taxpayer under IRC 267(b) or 707(b) attribution. A wholly owned subsidiary of the taxpayer’s holding company fails this test, as does a sibling of the taxpayer.
State licensing of QIs is fragmented. As of 2026, California, Colorado, Idaho, Maine, Nevada, Oregon, Virginia, and Washington require registration, bonding, or minimum capital. The California Department of Financial Protection and Innovation enforces the strongest regime under California Financial Code Sections 51000-51062, requiring a $1 million fidelity bond, errors-and-omissions coverage, and segregated client trust accounts subject to annual audit. Most national QIs (IPX1031 (Fidelity National Financial subsidiary), Asset Preservation Inc., 1031 Corp, and Investment Property Exchange Services) maintain California-compliant bonding even for non-California exchanges. The selection rubric used in Davis Polk client memoranda, and echoed in Sidley Austin and Latham & Watkins real estate tax desks, prioritizes (1) segregated qualified escrow accounts at top-tier banks, (2) minimum $5 million E&O coverage, (3) annual SSAE 18 SOC 1 Type II audit, and (4) parent-company financial strength. Smaller regional shops such as Edmund & Wheeler, Equity Advantage 1031, 1031 Pros, and Bayview 1031 are widely used for sub-$5 million deals but warrant the same diligence checklist.
For deals involving sophisticated buyers and sellers, the QI selection often gets folded into the broader transaction structuring work handled by an M&A advisor.
Like-Kind Property Definition for Real Estate
The like-kind standard for real property is the broadest in the federal tax code. Section 1031(a) requires only that the properties be “of like kind.” Treas. Reg. 1.1031(a)-1(b) takes the position that all real property is like-kind to all other real property regardless of grade, quality, or use. A residential rental duplex is like-kind to a Class A office tower; raw land is like-kind to a developed shopping center.
Categories that qualify: fee simple interests in land and improvements; leasehold interests of 30 years or more remaining (Rev. Rul. 78-72 and Treas. Reg. 1.1031(a)-1(c)); tenant-in-common interests structured under Rev. Proc. 2002-22 with no more than 35 co-owners; Delaware Statutory Trust (DST) beneficial interests qualified under Rev. Rul. 2004-86; conservation easements; mineral interests producing oil or gas (Rev. Rul. 68-331); water rights, air rights, and transferable development rights treated as real property under state law.
Categories that do not qualify: leasehold interests under 30 years; partnership interests (IRC 1031(a)(2)); corporate stock; trust beneficial interests other than DST interests under Rev. Rul. 2004-86; and goodwill (Rev. Rul. 75-557, reinforced by TCJA). Notes receivable secured by real estate do not qualify, which matters when an installment sale is structured alongside a 1031, as covered in our companion article on IRC Section 453 installment sales.
The Delaware Statutory Trust has become the dominant fractional-ownership 1031 vehicle since Rev. Rul. 2004-86 confirmed that a properly structured DST interest is treated as a direct interest in the underlying real property. DST sponsors (Inland Real Estate, JLL Income Property Trust, Capital Square, Passco) currently manage approximately $20 billion in DST assets per Mountain Dell Consulting industry tracking. The DST solves the “I have 30 days left and no deal under contract” problem because DST interests typically close within a week, but investors give up active management and accept a 5-7 percent acquisition load.
Boot Rules: Cash Boot, Mortgage Boot, and Non-Like-Kind Property
Boot is anything you receive in the exchange that is not like-kind property. Under IRC 1031(b) you recognize gain to the extent of boot received, capped at your realized gain. Boot comes in three flavors, each computed separately before netting.
Cash boot is the simplest. Sell for $1 million and only roll $900,000 into the replacement, and the $100,000 pocketed is boot. You recognize gain of $100,000 (or realized gain, if smaller), and the rest continues to defer.
Mortgage boot, more precisely net debt relief, arises when the replacement mortgage is smaller than the relinquished mortgage. Pay off a $600,000 mortgage on the relinquished property and only take on a $400,000 mortgage on the replacement, and you have $200,000 of mortgage boot. The IRS treats net debt relief as cash received under Treas. Reg. 1.1031(d)-2. Mortgage boot can be offset dollar-for-dollar by additional cash contributed, but cash boot cannot be offset by taking on more debt. This asymmetry, documented in Skadden real estate tax memos, trips up taxpayers who assume the two can be netted in either direction.
Non-like-kind-property boot arises when the replacement includes personal property or intangibles. Furniture, fixtures, and equipment (FF&E) bundled into a hotel sale, or operating contracts and trade names, are non-like-kind property under post-TCJA rules. The seller-side allocation between real property and FF&E (driven by IRC 1060) determines how much generates 1031-eligible proceeds.
| Boot Type | Trigger | Offset Mechanism | Tax Treatment |
|---|---|---|---|
| Cash boot | Sale proceeds not reinvested | None (cannot offset with debt) | Recognized gain up to realized gain, character matches underlying property |
| Mortgage boot (net debt relief) | Replacement debt less than relinquished debt | Cash contributed to exchange offsets dollar-for-dollar | Recognized gain up to realized gain |
| Non-like-kind property boot | FF&E, intangibles, personal property received | None for 1031 purposes (separate tax treatment per asset class) | Fair market value of boot recognized |
| Excess basis allocation | Replacement basis higher than relinquished basis | Carryover basis adjusted upward by recognized gain plus additional cash | Basis in replacement = relinquished basis + boot recognized + additional cash – boot received |
Boot character follows the relinquished property. Gain on investment real estate held more than one year is long-term capital gain at federal 0/15/20 percent plus the 3.8 percent net investment income tax under IRC 1411. Depreciation recapture under IRC 1250 is taxed at a maximum 25 percent federal rate to the extent of prior straight-line depreciation, and boot can fall into either bucket depending on the order rules under IRC 1250(d)(4).
Title-Holding Requirements: The Same-Taxpayer Rule
The same taxpayer who sold the relinquished property must take title to the replacement. This sounds simple and causes more failed exchanges than any rule besides the deadlines. If John Doe sells in his individual name, John Doe must take title to the replacement in his individual name. He cannot take title in a newly formed LLC unless the LLC is a disregarded entity under Treas. Reg. 301.7701-3.
A single-member LLC that has not elected corporate treatment is a disregarded entity, and title held by it is treated as held by its owner for federal tax purposes. This is the standard structuring pattern: the taxpayer forms a single-member LLC immediately before the replacement closing for liability isolation, and the IRS treats it as transparent for 1031. IRS guidance on single-member LLCs confirms the treatment.
Married couples filing jointly can title in either spouse’s name or both, with one caveat: in community property states (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, Wisconsin), property acquired during marriage is presumptively community property regardless of titling. Consistent titling is the safer practice.
Partnerships, S corporations, and C corporations are each separate taxpayers from their owners. A partnership exchange must have the partnership as the same taxpayer on both legs; individual partners cannot take their pro-rata share in kind and exchange individually. Solutions include the drop-and-swap (distribute a TIC interest before the sale) or swap-and-drop (exchange first, then distribute), with the latter safer because the post-exchange hold reinforces investment intent.
Trusts add another layer. A revocable grantor trust is disregarded for federal tax purposes under IRC 671-679, so titling in the grantor trust equals titling individually. An irrevocable non-grantor trust is a separate taxpayer and must be the same taxpayer on both legs. Estates can exchange if the relinquished property was held by the estate at the sale, but the 180-day clock does not pause for probate.
Recent IRS Guidance and Court Cases
The most consequential recent guidance is the final regulations under T.D. 9935 (November 2020), which defined “real property” for 1031 purposes after TCJA. The regulations adopted a hybrid approach: an asset is real property if it qualifies under the law of the state where it is located, or if it falls within a federal list of enumerated items including land, inherently permanent structures, structural components, and certain unsevered natural products. The federal list was deliberately broader than some states’ definitions to preserve 1031 eligibility for solar arrays, wind turbines, and HVAC systems.
The Tax Court has been active on the “held for investment” requirement. Reesink v. Commissioner, T.C. Memo. 2012-118, allowed 1031 treatment to a taxpayer who moved into the replacement property eight months after acquisition because the court found a genuine initial intent to rent, evidenced by a property management listing. Goolsby v. Commissioner, T.C. Memo. 2010-64, went the other way on a two-month timeline with weaker documentation. The lesson: rental-intent documentation at the time of acquisition matters more than calendar time.
On the boot-and-debt-relief interaction, Garcia v. Commissioner, 80 T.C. 491 (1983) and the regulations under 1.1031(d)-2 remain the controlling authorities. The interaction with the IRC 121 primary residence exclusion was addressed in Rev. Proc. 2005-14, which allows a taxpayer to combine the 121 exclusion (up to $250,000 single, $500,000 joint) on a mixed-use property with a 1031 deferral on the investment portion.
One area to watch: the Biden administration’s fiscal year 2024 and 2025 Greenbook proposals would have capped 1031 deferral at $500,000 per taxpayer per year ($1 million joint). The proposal did not advance in Congress, and the 2024 election results suggest the cap is off the table for the current session. Practitioners should nonetheless build flexibility into transaction structures to handle a future cap.
State Tax Conformity: CA, NY, FL, WA, TX, and the Clawback States
State conformity is largely consistent but with important exceptions. Most states with an income tax conform through rolling conformity to the IRC. The notable traps:
California: Conforms but enforces a clawback under Cal. Rev. & Tax. Code 18032 for exchanges of California-situs property into out-of-state replacement. When the taxpayer eventually sells the out-of-state replacement in a fully taxable sale, California reaches back to recapture the originally deferred gain. The taxpayer must file FTB Form 3840 annually until the deferred gain is recognized. The clawback applies regardless of residency at the eventual sale.
Oregon, Montana, Massachusetts: Parallel clawbacks under ORS 314.290, MCA 15-30-2110, and M.G.L. c. 62 Section 6F respectively.
Pennsylvania: Historically did not conform to IRC 1031 for personal income tax. Pennsylvania Act 53 of 2022 conformed Pennsylvania to IRC 1031 effective for tax years beginning after December 31, 2022. Exchanges completed before 2023 by Pennsylvania residents were fully taxable at the state level.
New York: Conforms automatically. New York City UBT on real estate held in pass-throughs conforms to 1031 deferral. Real estate transfer tax (RETT) is not deferred by 1031; transfer taxes are computed on gross consideration in each leg.
Florida: No state income tax. Florida documentary stamp tax on deeds and intangible tax on mortgages apply to each leg ($0.70 per $100 in most counties, $0.60 in Miami-Dade).
Texas: No state income tax and no deed transfer tax, making Texas one of the lowest-friction states for 1031 exchanges. Franchise tax applies to entities on a different base.
Washington: No state income tax, but the real estate excise tax (REET) under RCW 82.45 applies to each leg at progressive rates topping at 3.0 percent above $3,025,000. The 2021 capital gains tax (RCW 82.87) imposes 7 percent on long-term capital gains above $250,000 and conforms to federal 1031 deferral.
Worked Example: $1 Million Relinquished to $1.5 Million Replacement
Take a concrete example. The taxpayer owns a commercial building purchased 12 years ago for $600,000, with $200,000 of straight-line depreciation taken, leaving an adjusted basis of $400,000. Current value is $1,050,000, netting $1,000,000 after $50,000 of selling expenses. Mortgage balance: $300,000. He has identified a replacement at $1,500,000 plus $200,000 of closing costs and improvements, financed with a $600,000 mortgage plus additional cash.
| Line | Item | Amount |
|---|---|---|
| 1 | Relinquished property gross sale price | $1,050,000 |
| 2 | Less selling expenses | ($50,000) |
| 3 | Net sale price | $1,000,000 |
| 4 | Less mortgage payoff at closing | ($300,000) |
| 5 | Cash to QI exchange account | $700,000 |
| 6 | Adjusted basis (original cost $600,000 less depreciation $200,000) | $400,000 |
| 7 | Realized gain (Line 3 – Line 6) | $600,000 |
| 8 | Replacement property purchase price | $1,500,000 |
| 9 | Replacement closing costs and improvements | $200,000 |
| 10 | Total replacement cost (Line 8 + Line 9) | $1,700,000 |
| 11 | Less replacement mortgage | ($600,000) |
| 12 | Less QI exchange funds applied | ($700,000) |
| 13 | Additional cash required from taxpayer | $400,000 |
| 14 | Net debt change (Line 11 – Line 4) | +$300,000 (additional debt taken on) |
| 15 | Mortgage boot (debt relief over debt assumed) | $0 (no net debt relief) |
| 16 | Cash boot (proceeds not reinvested) | $0 (all QI funds applied to replacement) |
| 17 | Total boot recognized | $0 |
| 18 | Recognized gain (lesser of Line 7 and Line 17) | $0 |
| 19 | Deferred gain (Line 7 – Line 18) | $600,000 |
| 20 | Basis in replacement (relinquished basis + recognized gain + additional cash – boot) | $400,000 + $0 + $400,000 – $0 = $800,000 |
The taxpayer has rolled a $1,000,000 net sale into a $1,700,000 all-in replacement with $400,000 of additional cash and $300,000 of additional mortgage. Zero gain is recognized. The full $600,000 of appreciation plus $200,000 of depreciation recapture exposure continues to defer, with a new basis of $800,000. When he eventually sells in a taxable transaction, the deferred gain plus future appreciation will be recognized then, unless the property passes through his estate at death (IRC 1014 provides a stepped-up basis that effectively eliminates the deferred gain forever).
Now flip one variable. The taxpayer pockets $100,000 at closing instead of reinvesting it. Cash boot is $100,000, recognized gain is $100,000 (capped by realized gain of $600,000). The $100,000 triggers as 25-percent-rate unrecaptured Section 1250 gain under IRC 1(h)(6) to the extent of prior depreciation; federal tax is $25,000 plus $3,800 NIIT, plus state tax. Replacement basis adjusts to $400,000 + $100,000 + $400,000 – $100,000 = $800,000. The companion form for any partial recognition structured as a seller note is IRS Form 6252.
Five Common 1031 Mistakes That Kill Exchanges
The same mistakes recur across Tax Court decisions, IRS examinations, and QI claims files. Five patterns account for most failed exchanges.
Mistake 1: Missing the 45-day or 180-day deadline by even one day. The deadlines are statutory and cannot be extended except by IRS disaster declaration. Industry practice is to embed the deadline into the purchase contract as a hard outside closing date with earnest money becoming non-refundable past day 170.
Mistake 2: Related-party transactions under IRC 1031(f). Exchanging into property acquired from a related party (siblings, parents, children, spouses, controlled entities) triggers a two-year holding requirement on both legs. If either party disposes within two years, the deferral is undone. Teruya Brothers v. Commissioner, 580 F.3d 1038 (9th Cir. 2009) is the leading case denying 1031 treatment to a related-party exchange the court found to be a tax-avoidance device.
Mistake 3: Taxpayer mismatch. The relinquished and replacement properties must be held by the same taxpayer for federal tax purposes. Switching from individual title to a multi-member LLC, or from one spouse to both, between closings can blow the exchange. Disregarded-entity transitions are safe; entity-classification changes are not.
Mistake 4: Partial-exchange computation errors. When the replacement is smaller than the relinquished proceeds, or carries less debt, the boot computation must be done correctly. Many taxpayers assume cash boot can be netted against added debt, which is not how the regulations work (debt relief can be offset by added cash, but cash received cannot be offset by added debt).
Mistake 5: QI bonding and segregation gaps. The 2008-2009 collapses of LandAmerica 1031 Exchange Services and 1031 Tax Group LLC (the Edward H. Okun scheme covered in the New York Times) left taxpayers exposed to $500 million-plus in lost funds. LandAmerica had commingled exchange funds with corporate operating cash and invested in auction-rate securities that froze during the credit crisis. Earlier defalcations, including the Tom Davis Cornerstone Mortgage 1031 case, are catalogued in FEA consumer alerts and discussed in detail in major BigLaw memos from Skadden and Davis Polk. Before sending funds to a QI, verify (1) segregated qualified trust account with a top-tier bank, (2) $1 million fidelity bond and $5 million E&O coverage, (3) FEA membership, and (4) parent-company financial strength.
Choosing the Right Qualified Intermediary: A Vetting Checklist
QI selection is a procurement decision with real money at stake. The QI will hold your sale proceeds for up to 180 days, prepare the exchange documents that the IRS will examine, and coordinate with your tax counsel on edge cases. The criteria that matter most:
- Segregated qualified trust accounts. Each exchange should sit in its own account at a major bank (Wells Fargo, JPMorgan Chase, Bank of America, Citibank, US Bank). Pooled accounts commingling multiple taxpayers’ funds are a risk indicator.
- Bonding and insurance. Minimum $1 million fidelity bond, minimum $5 million errors-and-omissions, written confirmation on request.
- Audit reports. Annual SSAE 18 SOC 1 Type II audit, available on request under NDA. The audit confirms internal controls around fund segregation and exchange documentation.
- State licensing. Active registration in California, Colorado, Idaho, Maine, Nevada, Oregon, Virginia, and Washington as applicable.
- Parent company strength. The major national QIs are owned by Fortune 500 title insurers (Fidelity National Financial, First American Financial, Stewart Title, Old Republic). Independent QIs with weaker balance sheets carry higher counterparty risk.
- Experience with your transaction type. Complex exchanges (reverse, improvement, multi-asset, partnership drop-and-swap, FIRPTA sellers) require senior personnel. Ask for references on closed deals of similar size within the last 12 months.
- Fee transparency. Standard fee for a basic forward exchange is $1,000-$1,500. Improvement and reverse exchanges run $5,000-$15,000 because they require an Exchange Accommodation Titleholder (EAT). Get the fee schedule in writing before engagement.
- Interest on exchange funds. Most QIs retain the interest on held funds as part of compensation. On a $5 million exchange held 120 days at 4 percent, the interest is roughly $65,000, which is material. Negotiate an interest-share or flat fee.
The top national QIs, all FEA members, include IPX1031 (Fidelity National Financial), Asset Preservation Inc. (Stewart Title), 1031 Corp, First American Exchange Company, Old Republic Exchange, Investment Property Exchange Services, and Accruit (Inspira Financial). Regional QIs with strong reputations include Exeter 1031 Exchange Services (California), Realty Exchange Corporation (Virginia), Edmund & Wheeler (New England), Equity Advantage 1031 (Pacific Northwest), 1031 Pros, and Bayview 1031 (Florida). The choice between national and regional typically comes down to whether your transaction involves multiple states or specialized asset types.
For deals where the exchange runs alongside an asset sale of an operating business (hotel, assisted living, parking operation), the QI selection gets coordinated with the broader transaction structure, including the choice between an asset deal versus a stock deal on the operating side. The 1031 only runs on the real estate component; the operating business is handled separately under IRC 1060 allocation.
Reverse and Improvement Exchanges Through the QI
Two specialized variants come up often enough to cover. The reverse exchange is governed by Revenue Procedure 2000-37, which created a safe harbor allowing the taxpayer to acquire the replacement property before selling the relinquished property. The mechanism: an Exchange Accommodation Titleholder (EAT), typically a single-purpose LLC owned by the QI, takes title to the replacement and holds it for up to 180 days while the taxpayer markets and sells the relinquished property. On the relinquished sale day, the QI assigns the EAT’s interest to the taxpayer in exchange for the sale proceeds.
Reverse exchanges solve the inverted-market problem where the taxpayer has found the right replacement but has not yet sold the relinquished property. They are more expensive ($10,000-$25,000 in QI fees versus $1,500 forward), carry interim financing complexity (the EAT needs bridge debt to fund acquisition), and require careful structuring of the EAT’s economic interest to maintain the Rev. Proc. 2000-37 safe harbor.
The improvement exchange (build-to-suit or construction exchange) allows the taxpayer to use exchange proceeds to fund improvements on the replacement property before taking title. The EAT acquires raw land or an existing building, the QI directs construction draws using exchange proceeds, and the improved property is transferred to the taxpayer. The 180-day deadline still applies, so construction must be substantially complete within 180 days. Improvement exchanges are most common for renovation projects rather than ground-up construction. Not every QI is set up for these variants; confirm capability before engagement.
Material Adverse Change and Other Mid-Exchange Risks
Once the relinquished property has closed and the clock is running, the taxpayer is exposed to mid-exchange risks the QI cannot fully insure against. The replacement could fail environmental inspection, the lender could pull financing, or a material adverse change could give the buyer grounds to terminate. These risks are allocated in the replacement purchase agreement through representations, warranties, and a material adverse effect clause, but if the replacement falls through past day 45 with no backup identified, the exchange fails and the cash proceeds become taxable.
Insurance against failed exchanges is largely unavailable, although a few specialty carriers write “tax indemnity” policies on a bespoke basis. The practical hedge is the three-property identification rule: identify three credible replacements at the start so that two can fall through. The cost of carrying three options through diligence (legal review, environmental Phase I, financial diligence) is real but cheap relative to a full tax bill.
The other mid-exchange risk is QI failure. The 2008-2009 collapses are still cited in QI selection memos a decade-plus later. Modern controls (segregated trust accounts, bonding, audits, FEA membership) have made repeat failures rare, but not zero. For exchanges above $5 million in proceeds, most institutional sellers will only work with one of the top-tier national QIs.
Reporting the Exchange: Form 8824
The taxpayer files IRS Form 8824, Like-Kind Exchanges, with the federal return for the year the relinquished property was sold, applying the safe-harbor mechanics under Treas. Reg. 1.1031(k)-1 and the underlying statute at IRC 1031. Form 8824 reports the description of both properties, the identification and exchange dates, the realized and recognized gain, basis in the replacement, and related-party information. The form is filed once per exchange.
The instructions walk through Lines 12-25. Line 15 captures cash boot, Line 16 captures fair market value of non-like-kind property received, Line 17 captures total boot, Line 18 captures adjusted basis plus net amounts paid, Line 19 the realized gain, Line 20 the smaller of recognized gain and realized gain, and Line 25 the basis of like-kind property received. A small error in basis or boot can carry forward for decades.
For state purposes, California requires the additional FTB Form 3840 annually until the deferred gain is recognized. Oregon, Montana, and Massachusetts have similar requirements. New York, Texas, Florida, and Washington do not require additional reporting.
Audit risk on 1031 exchanges is moderate. The IRS examines exchanges with some regularity, particularly large dollar amounts, related-party exchanges, drop-and-swap partnerships, and exchanges with significant boot. Tax Court decisions including Bartell v. Commissioner, 147 T.C. 140 (2016) on reverse-exchange parking arrangements and North Central Rental & Leasing v. United States, 779 F.3d 738 (8th Cir. 2015) on related-party recharacterization show how aggressively the Service polices QI structures. The QI’s exchange documentation (exchange agreement, assignment notices, identification letters, closing statements) is the primary audit defense. Keep a complete file for at least seven years after the eventual taxable sale of the replacement property.
TLDR and Seven Takeaways
The qualified intermediary is the structural lynchpin of any 1031 exchange. Without a properly engaged QI, the safe harbor under Treas. Reg. 1.1031(k)-1(g)(4) is unavailable, and the sale becomes immediately taxable. The QI is more than a custodian: it is the contractual party that takes the assignment of the taxpayer’s rights, prepares the exchange paperwork, and structures the fund flow so the taxpayer never has actual or constructive receipt of the sale proceeds.
- Engage the QI before the relinquished property closes. The exchange agreement and assignment notices must be in place before the closing wire goes out. A retroactive engagement does not cure a botched closing.
- Confirm independence under the disqualified-person rules. Your CPA, attorney, real estate broker, and employees within the past two years cannot serve as your QI. The two-year lookback is rigid.
- Verify segregation, bonding, and audits. Segregated qualified trust accounts at major banks, minimum $1 million fidelity bond, minimum $5 million errors-and-omissions, and annual SSAE 18 SOC 1 Type II audit are the baseline.
- Track the 45-day and 180-day deadlines from day zero. Identification by day 45, closing by day 180, and a Form 4868 extension if the exchange crosses a tax-year boundary. The deadlines are statutory.
- Document investment intent for the replacement property. A rental listing, a property management agreement, an appraisal, and Schedule E reporting all reinforce the “held for investment” requirement.
- Watch the same-taxpayer rule. Single-member disregarded LLCs are safe; multi-member LLCs and partnerships introduce taxpayer-identity issues. Plan the title structure before the relinquished closing.
- Know your state’s conformity and clawback rules. California, Oregon, Montana, and Massachusetts all enforce clawback regimes. File state continuation forms (FTB 3840 in California) annually until the deferred gain is recognized.
A well-executed 1031 exchange compounds wealth across decades, particularly in conjunction with the IRC 1014 step-up in basis at death that eliminates the deferred gain permanently if the property passes through an estate. A badly executed exchange triggers a full tax bill on the entire embedded gain plus depreciation recapture plus state tax plus penalties. The difference is usually the quality of the QI, the discipline of the timeline, and the rigor of the documentation. Every dollar spent on QI selection and tax counsel up front saves multiples on the back end.
