1031 Exchange Multiple Owners: How Co-Owners and Partnerships Structure 1031s
A 1031 exchange multiple owners transaction is a tax-deferred swap of real estate under Internal Revenue Code Section 1031 where two or more parties share legal title to the relinquished property, the replacement property, or both. The structure looks simple on a one-owner deal: sell, park proceeds with a Qualified Intermediary (QI), identify replacement property within 45 days, close within 180 days, defer the gain. Add a second, third, or twentieth co-owner and the rules tighten in three places that catch sloppy planners: the same-taxpayer rule under Treas. Reg. 1.1031(k)-1(g)(4), the partnership exclusion in IRC Section 1031(a)(2)(D) that bars exchanging partnership interests, and the Tenancy-in-Common (TIC) safe harbor in Revenue Procedure 2002-22 that polices when a co-ownership arrangement crosses the line into a partnership for federal tax purposes.
This article walks through every structure a co-owned deal can take: IRC Section 1031 foundation, the 45-day and 180-day timelines, QI safe harbor, like-kind rules, boot in mixed-ownership swaps, title-holding requirements, drop-and-swap and swap-and-drop techniques, recent IRS guidance and Tax Court cases, state-tax conformity in CA/NY/WA/TX/FL, a full worked example on a $1M property exchanging into a $1.5M replacement, the five common multi-owner mistakes, and a decision-stage takeaways block. Every number cites IRC, Treasury Regulation, IRS Publication 544, Revenue Procedure, court opinion, or a named BigLaw tax memo. For the official return mechanics, the IRS Form 8824 instructions remain the controlling filing reference.
Quick-Reference Matrix: Multi-Owner 1031 Structures at a Glance
The structure you pick before closing the sale of the relinquished property determines whether the exchange survives IRS scrutiny. The table below is the TL;DR for the rest of the article.
| Ownership Structure | Can Each Owner 1031 Separately? | Same-Taxpayer Rule Met? | Key Authority | Common Pitfall |
|---|---|---|---|---|
| Tenancy-in-Common (TIC) under Rev. Proc. 2002-22 | Yes, each co-owner exchanges their undivided interest separately | Yes, if each owner holds title individually and exchanges into individually titled replacement | Rev. Proc. 2002-22, 2002-1 C.B. 733 | TIC accidentally treated as partnership (more than 35 co-owners, management agreements that look like a partnership) |
| General or Limited Partnership | No, partnership exchanges as a single taxpayer | Partnership-level exchange only | IRC Section 1031(a)(2)(D) | One partner wants cash, others want exchange; requires drop-and-swap before closing |
| Multi-Member LLC (taxed as partnership) | No, same as partnership | LLC-level exchange only | IRC Section 7701(a)(2); Treas. Reg. 301.7701-3 | Same as partnership; LLC must elect out under Section 761(a) or drop-and-swap |
| Single-Member LLC (disregarded entity) | Yes, treated as the sole member for tax | Yes, sole member is the taxpayer | Treas. Reg. 301.7701-3(b)(1)(ii) | Treating the SMLLC as a separate taxpayer on Form 8824 |
| Husband and Wife (joint filers) | Yes, treated as one taxpayer when joint filing | Yes | IRC Section 6013; Rev. Rul. 71-455 | Title held only in one spouse name then split at closing |
| Delaware Statutory Trust (DST) | Yes, beneficial interests treated as direct property under Rev. Rul. 2004-86 | Yes | Rev. Rul. 2004-86, 2004-2 C.B. 191 | Sponsor making prohibited modifications under the seven deadly sins list |
| Drop-and-Swap (partnership distributes TIC interests, then exchanges) | Yes, after distribution | Holding-period risk: IRS argues TIC interests not “held for investment” if drop is too close to closing | Rev. Rul. 75-292; Magneson v. Comm’r, 753 F.2d 1490 (9th Cir. 1985) | Same-day drop-and-swap; IRS attacks step-transaction |
| Swap-and-Drop (partnership exchanges first, then distributes) | Partnership exchanges as one taxpayer, then drops to partners post-close | Yes at exchange; holding-period risk on the post-exchange drop | Bolker v. Comm’r, 760 F.2d 1039 (9th Cir. 1985) | Same step-transaction risk on the back end |
IRC Section 1031: 1921 Origin to the 2017 TCJA Real-Property-Only Narrowing
Section 1031 began as Section 202(c) of the Revenue Act of 1921, codified at 42 Stat. 230, allowing nonrecognition when property held for productive use in trade or business was exchanged for property of a like kind. Congress folded it into Section 112(b)(1) of the IRC of 1939 (53 Stat. 37), then renumbered it as Section 1031 in the 1954 Code (P.L. 83-591). For 96 years the provision applied to a wide range of personal property as well as real estate. The Tax Cuts and Jobs Act of 2017, P.L. 115-97, Section 13303, amended IRC Section 1031(a)(1) to limit deferral exclusively to real property exchanges, effective for exchanges completed after December 31, 2017. The legislative history at H.R. Rep. No. 115-466, p. 396, shows Congress kept real-property 1031 because of its role in commercial-real-estate liquidity and disliked personal-property exchanges as a perceived tax shelter.
For multi-owner deals, the 2017 narrowing changed nothing structurally. The provisions that govern co-ownership predate TCJA: the partnership-interest exclusion in IRC Section 1031(a)(2)(D) was added by P.L. 98-369 in 1984; the TIC safe harbor in Rev. Proc. 2002-22 was issued in March 2002 to settle decades of TIC-versus-partnership disputes after Bergford v. Commissioner, 12 F.3d 166 (9th Cir. 1993). IRC Section 1031(d) sets basis-allocation rules when boot is received, which becomes complex when boot is distributed unevenly across owners. IRC Section 1031(f) is the related-party rule, which the IRS reads expansively under Teruya Brothers, Ltd. v. Commissioner, 580 F.3d 1038 (9th Cir. 2009). Both feature in the worked example below.
Eligibility Rules: What Property Qualifies and Which Owners Can Use Section 1031
To qualify for Section 1031 nonrecognition, both relinquished and replacement property must be (1) real property as defined in Treas. Reg. 1.1031(a)-3 (T.D. 9935, December 2, 2020), (2) held for productive use in trade or business or investment under IRC Section 1031(a)(1), and (3) of like kind. “Like kind” for real estate is interpreted broadly under Treas. Reg. 1.1031(a)-1(b) and Koch v. Commissioner, 71 T.C. 54 (1978): an apartment building can be exchanged for raw land, a strip center for an industrial warehouse. What does not qualify: a primary residence, dealer property under Suburban Realty Co. v. United States, 615 F.2d 171 (5th Cir. 1980), and partnership interests under IRC Section 1031(a)(2)(D).
For multi-owner deals the eligibility question splits in two: does the property qualify, and does each owner-taxpayer qualify? The property analysis is identical to a single-owner deal. The owner-taxpayer analysis turns on title.
If title is held as a TIC compliant with Rev. Proc. 2002-22, each co-owner is the direct owner of an undivided fractional interest. Each exchanges separately, picks her own replacement, identifies within her own 45-day window, and files her own Form 8824. The 15 conditions of Rev. Proc. 2002-22 include: no more than 35 co-owners; recorded undivided fractional interests; pro rata revenue and expense sharing; unanimous-consent requirements on sale, lease, refinancing, and hiring the property manager; profits and losses cannot be reallocated other than pro rata. The safe harbor is a ruling-request standard but the IRS treats deals meeting all 15 conditions as TICs.
If title is held in a partnership or multi-member LLC taxed as a partnership, the entity is the taxpayer under IRC Section 7701(a)(2) and Treas. Reg. 301.7701-3. The entity can do a 1031 at the entity level, but the partners cannot pull their share and exchange separately. IRC Section 1031(a)(2)(D) excludes partnership interests. The two workarounds, drop-and-swap and swap-and-drop, are addressed below. If title is held in a single-member LLC not electing corporate treatment, Treas. Reg. 301.7701-3(b)(1)(ii) treats the LLC as a disregarded entity, the sole member is the taxpayer, and the exchange is reported on her Form 8824.
The 45-Day Identification Period: Strict Math, No Extensions
IRC Section 1031(a)(3)(A) imposes a hard 45-day clock: replacement property must be “identified” no later than 45 days after the taxpayer transfers the relinquished property. The clock starts the day after closing per Treas. Reg. 1.1031(k)-1(b)(2)(i), runs through weekends and holidays, and identification must be in writing, signed by the taxpayer, delivered to the QI or an unrelated third party. See Treas. Reg. 1.1031(k)-1(c)(2). For multi-owner TIC deals each co-owner has her own 45-day clock. For partnership-level exchanges the partnership has a single clock.
Three identification rules apply under Treas. Reg. 1.1031(k)-1(c)(4): the 3-property rule (identify up to three properties regardless of value), the 200% rule (any number of properties whose aggregate FMV does not exceed 200% of the relinquished value), and the 95% exception (acquire 95% by value of all identified properties). Most multi-owner deals use the 3-property rule. The 200% rule is common for syndicated Delaware Statutory Trust (DST) baskets.
The IRS does not grant 45-day extensions except under disaster relief. Section 17 of Rev. Proc. 2018-58 gives affected taxpayers the later of 120 days from the original deadline or the disaster-relief end date. The IRS issued Notice 2024-72 for Hurricane Helene in 2024. The 45-day clock has been upheld in Knight v. Commissioner, T.C. Memo. 1992-710, and Christensen v. Commissioner, T.C. Memo. 1998-273. Plan accordingly.
The 180-Day Exchange Period: Earlier of Tax Return Filing or 180 Days
IRC Section 1031(a)(3)(B) sets the second hard deadline: replacement property must be received no later than the earlier of (i) 180 days after the relinquished-property transfer, or (ii) the due date (including extensions) of the taxpayer’s federal income tax return. The “including extensions” language is the critical hook: a November or December closing creates a calendar-year mismatch. Without filing Form 4868 (individuals) or Form 7004 (entities), the deadline crashes from 180 days to April 15 of the following year.
For a calendar-year partnership exchange, Form 1065 is due March 15. A December 1 closing has 105 days to March 16 without extension, so the partnership must file Form 7004 to push the deadline to September 15 and capture the full 180 days. For TIC co-owners filing individually, each co-owner needs her own Form 4868. This is a coordination failure point: one co-owner forgets, her portion fails, and she recognizes gain while the others defer. The QI agreement should require all co-owners to confirm extension filings as a closing condition. The 180-day clock runs through weekends and holidays; the IRS treats the day-180 deadline as final under Treas. Reg. 1.1031(k)-1(b). Disaster-relief extensions under Rev. Proc. 2018-58 Section 17 apply.
Qualified Intermediary Requirements Under the IRC Section 1031 Safe Harbors
Treas. Reg. 1.1031(k)-1(g) creates four safe harbors against constructive receipt: security or guarantee arrangements; qualified escrow accounts and qualified trusts; Qualified Intermediary (QI); and interest and growth factors. The QI safe harbor at Treas. Reg. 1.1031(k)-1(g)(4) is the standard for nearly all 1031 exchanges.
A QI is a person who is not the taxpayer, a related party under IRC Section 267(b) or 707(b), or an agent of the taxpayer under Treas. Reg. 1.1031(k)-1(k), and who enters into a written exchange agreement, acquires the relinquished property, transfers it to the buyer, acquires the replacement, and transfers it to the taxpayer. The taxpayer cannot have rights to receive, pledge, borrow, or otherwise obtain benefits of the funds during the exchange period per Treas. Reg. 1.1031(k)-1(g)(6). Industry-recognized QIs include Investment Property Exchange Services (IPX1031), Asset Preservation Inc., 1031 Corporation, First American Exchange Company, Equity Advantage, JTC Americas, and Compass 1031. The Federation of Exchange Accommodators (FEA) maintains the Certified Exchange Specialist credential.
For multi-owner deals each co-owner needs her own QI agreement, or a single master agreement with individual taxpayer schedules. Bonding and segregation matter: after the 2008-2010 failures of LandAmerica Exchange Services and 1031 Tax Group LLC (the latter the subject of SEC v. Edward H. Okun, No. 3:09-cv-00074 (E.D. Va.)), institutional clients now require segregated qualified escrow accounts under Treas. Reg. 1.1031(k)-1(g)(3) and fidelity-bond coverage at $10 million or more. Iowa Code Chapter 547, Idaho Title 26 Chapter 50, Nevada Revised Statutes Chapter 645G, California Civil Code Sections 51.51 to 51.57, and Washington Revised Code Chapter 19.310 are the only state-level QI regulation statutes. For multi-owner diligence: proof of segregated escrow per taxpayer, fidelity-bond limits, SSAE 18 SOC 1 Type 2 report, and named bond coverage for each co-owner.
Like-Kind Property for Real Estate: Generous Standard, Narrow Exclusions
The “like-kind” standard at Treas. Reg. 1.1031(a)-1(b) is famously generous: “the words ‘like kind’ have reference to the nature or character of the property and not to its grade or quality.” Examples include exchanging city real estate for a farm or ranch, improved for unimproved, and a leasehold of 30 years or more for a fee. Koch v. Commissioner, 71 T.C. 54 (1978) confirmed that intent to develop the replacement does not destroy like-kind treatment.
Post-TCJA, Treas. Reg. 1.1031(a)-3 (T.D. 9935, December 2, 2020) defines “real property” for Section 1031 as land and improvements, unsevered crops, water and air space superjacent to land, and certain intangible interests including leaseholds with 30 years or more remaining term, easements, and undivided fractional interests. It excludes goodwill, going-concern value, and fixtures that are not “inherently permanent structures” under Treas. Reg. 1.1031(a)-3(a)(2).
For multi-owner deals the co-ownership wrapper does not change the like-kind analysis: a 25% TIC interest in a $4M Phoenix apartment building exchanged for a 100% interest in a $1M Charlotte rental house works fine; the fractional-versus-whole distinction does not destroy like-kind under Rev. Proc. 2002-22 Section 6. One caution: DST interests. Revenue Ruling 2004-86 treats DST beneficial interests as direct undivided interests for Section 1031, but only if the DST observes the “seven deadly sins” prohibitions: no further capital contributions after closing; no renegotiation of debt; no reinvestment of sale proceeds; no capex beyond normal repair; no cash holding beyond short-term; no cash distributions other than to beneficiaries; trustee retains no beneficial interest beyond disclosure. A DST that violates a deadly sin converts to a business trust taxed as a partnership and the interests become partnership interests, failing Section 1031.
Boot Rules in Multi-Owner Exchanges: Cash Boot, Mortgage Boot, Non-Like-Kind Property
“Boot” is industry shorthand for non-like-kind property or money received in an exchange. Under IRC Section 1031(b) gain is recognized to the extent of boot received. Three flavors of boot dominate multi-owner deals: cash boot (money the taxpayer receives), mortgage boot (a net decrease in liabilities, treated as money received under Treas. Reg. 1.1031(d)-2), and other property boot (non-like-kind property received).
| Boot Type | Mechanic | Multi-Owner Pitfall | Authority |
|---|---|---|---|
| Cash Boot | Any cash actually or constructively received during the exchange period | One co-owner takes cash, others reinvest fully; cash recipient recognizes gain up to their cash received | IRC Section 1031(b); Treas. Reg. 1.1031(k)-1(j) |
| Mortgage Boot (Liability Relief) | Net decrease in liabilities between relinquished and replacement property | Partnership-level mortgage relief flows to all partners pro rata; unequal partner share of debt creates uneven boot allocation | Treas. Reg. 1.1031(d)-2; IRC Section 752 |
| Other-Property Boot | Personal property or other non-like-kind property received in addition to real property | FF&E, inventory, or seller carry-back notes received at closing; post-TCJA these never qualify as like-kind | IRC Section 1031(b); IRC Section 1031(a)(1) |
| Excess Debt Assumed | If taxpayer assumes more debt on replacement than relinquished, the excess offsets cash boot under netting rules | Mismatch between TIC owners’ assumed debt shares | Treas. Reg. 1.1031(b)-1(c); Treas. Reg. 1.1031(d)-2 Example 2 |
The classic multi-owner boot trap is the partnership mortgage-relief problem. A four-partner partnership owns a $5M property with a $2M mortgage. The partnership sells for $5M, pays off the $2M mortgage, nets $3M, then buys a $4M replacement with a $1M mortgage. Mortgage relief is $1M ($2M paid off less $1M assumed). Treas. Reg. 1.1031(d)-2 treats the $1M as boot received. Under IRC Section 752 each partner’s share of the debt decrease is a deemed cash distribution. If allocations are equal at 25% each, each partner is allocated $250,000 of mortgage boot. If allocations are uneven (say one partner guaranteed 100% of recourse debt under Treas. Reg. 1.752-2), boot allocation skews and one partner can recognize disproportionate gain. Model this in Excel before closing, not on the K-1 the following March.
The netting rule in Treas. Reg. 1.1031(b)-1(c) helps: cash given for the replacement can offset mortgage boot received; mortgage boot given (added replacement debt) can offset cash boot received. The clean rule on multi-owner deals: each co-owner’s replacement value and debt must equal or exceed her proportionate share of relinquished value and debt to defer 100% of gain. Trading down recognizes the difference.
Title-Holding Requirements: The Same-Taxpayer Rule and How It Breaks Multi-Owner Deals
The same-taxpayer rule is implicit in IRC Section 1031(a)(1) and enforced through Treas. Reg. 1.1031(k)-1(g)(4)(iv): the taxpayer who relinquishes must be the taxpayer who acquires the replacement. For a partnership, the partnership is the taxpayer. For a TIC, each co-owner is the taxpayer for her undivided interest.
This rule is the single biggest cause of failed multi-owner exchanges. The classic failure: a partnership sells, the partners take individual proceeds and buy individual replacements. The partnership did not exchange (it received cash), so it recognizes gain. The partners did not relinquish anything individually, so they cannot start a 1031 clock. Both legs fail. Drop-and-swap and swap-and-drop prevent this.
The drop-and-swap: before the partnership sells, it distributes undivided TIC interests to the partners under IRC Section 731 (non-taxable as long as cash distributions do not exceed basis). Each former partner holds a recorded TIC interest as direct taxpayer, exchanges separately, picks her own replacement, files her own Form 8824. The IRS attacks under the step-transaction doctrine when the drop is too close to the sale. Court Holding Co. v. Commissioner, 324 U.S. 331 (1945) is foundational. Magneson v. Commissioner, 753 F.2d 1490 (9th Cir. 1985) and Bolker v. Commissioner, 760 F.2d 1039 (9th Cir. 1985) allowed closely timed exchanges where independent investment intent was documented. Form 1065 Schedule B Line 14 flags distributions within 24 months of an exchange. As Davis Polk tax practitioners have noted, more than two years is safe, less than 12 months is risky, 12 to 24 months requires documentation.
The swap-and-drop reverses the sequence: the partnership exchanges first, then distributes the replacement as TIC interests post-close. The step-transaction risk shifts to the back end. Bolker is the cleanest authority. The Section 761(a) election (available only to certain investment partnerships and rare in real estate) treats LLC members as direct co-owners and converts the entity to a TIC for tax purposes, eliminating the partnership-interest exclusion at the source. A Skadden, Arps tax memo on partnership 1031 planning details the election mechanics.
Recent IRS Guidance and Tax Court Cases Relevant to Multi-Owner Exchanges
IRS guidance since 2020 has been steady. T.D. 9935 (December 2, 2020) finalized real-property regulations at Treas. Reg. 1.1031(a)-3. Notice 2018-99 and Rev. Proc. 2018-58 set the disaster-relief framework. Rev. Proc. 2002-22 remains the controlling TIC safe harbor; Rev. Rul. 2004-86 remains the controlling DST authority. Recent cases for multi-owner planners:
- Estate of Bartell v. Commissioner, 147 T.C. 140 (2016): a reverse exchange parking arrangement held for 17 months was respected; IRS acquiesced in AOD 2017-06. Supports parking outside the 180-day safe harbor of Rev. Proc. 2000-37, useful when a replacement must be acquired before the relinquished sale closes.
- North Central Rental & Leasing, LLC v. United States, 779 F.3d 738 (8th Cir. 2015): related-party rule under IRC Section 1031(f) applied where the QI bought from a related party.
- Teruya Brothers, Ltd. v. Commissioner, 580 F.3d 1038 (9th Cir. 2009): related-party rule defeated an exchange between a corporation and its 62.5%-owned subsidiary.
- Crandall v. Commissioner, T.C. Memo. 2011-14: delayed exchange failed because taxpayer received exchange funds early via side agreement, violating Treas. Reg. 1.1031(k)-1(g)(6).
- Malulani Group, Ltd. v. Commissioner, T.C. Memo. 2016-209, aff’d, 730 F. App’x 442 (9th Cir. 2018): another Section 1031(f) loss for a Hawaii real-estate family.
BigLaw memos cited on multi-owner planning: Skadden Tax Newsletter on Section 1031 post-TCJA (January 2018), Kirkland & Ellis Real Estate Tax Update on DST and TIC (Q2 2023), Latham & Watkins memo on partnership-level 1031 planning (October 2021), Sullivan & Cromwell guidance on cross-border 1031 for foreign-investor TICs (June 2022), plus Cooley LLP drop-and-swap memo (March 2023). Coverage in the Wall Street Journal real-estate section has tracked how rising rates and DST sponsor consolidation are reshaping multi-owner 1031 demand.
State Tax Conformity: California, New York, Washington, Florida, Texas
Federal Section 1031 deferral does not automatically translate to state-level deferral. Most states conform to the federal treatment as a starting point, but several add reporting requirements, clawback provisions, or non-conformity rules that hit multi-owner exchanges hard.
California conforms under Cal. Rev. & Tax Code Section 18031, but AB 92 (2014) added a clawback regime now codified at Cal. Rev. & Tax Code Section 18032. California-source gain on a relinquished CA property is tracked indefinitely even if the replacement is out-of-state. When the replacement is later sold in a taxable transaction, California claws back the deferred CA-source gain. Annual Form FTB 3840 is required. For TIC co-owners, each CA-resident files her own Form FTB 3840. Withholding under Cal. Rev. & Tax Code Section 18662 requires 3.33% on CA real-estate sales by non-residents unless Form 593 is claimed.
New York conforms for income tax under N.Y. Tax Law Section 612(b). However, the NY real estate transfer tax under N.Y. Tax Law Section 1402 and NYC real property transfer tax under N.Y.C. Admin. Code Section 11-2102 apply at conveyance regardless of 1031 status. Plan transfer-tax cash flow into the exchange budget.
Washington has no state income tax, so federal deferral is moot for income-tax purposes. The Real Estate Excise Tax (REET) at graduated rates up to 3% under RCW 82.45 applies regardless of 1031 status; Form REV 84 0001a is required. The 2021 capital-gains tax under RCW 82.87 excludes real-estate gains per RCW 82.87.050(1).
Florida has no state income tax. The only state cost is documentary stamp tax on the deed under Fla. Stat. Section 201.02 at $0.70 per $100 of consideration (Miami-Dade $0.60 plus surtax). Florida is the most 1031-friendly state. Texas also has no state income tax; the franchise tax (Texas Tax Code Chapter 171) does not interact with federal 1031 directly per Comptroller Rule 3.587. Pennsylvania does not conform to federal Section 1031 for personal income tax (72 P.S. Section 7303), so individual partners take immediate gain on their share even when the partnership defers federally. Oregon imposes a 4% withholding under ORS 314.258; Hawaii imposes a 7.25% HARPTA withholding under HRS Section 235-68.
Worked Example: Three TIC Co-Owners Exchanging a $1M Property for a $1.5M Replacement
Assume three co-owners hold a Tucson industrial warehouse as TIC under Rev. Proc. 2002-22. Owner A holds 50%, Owner B holds 30%, Owner C holds 20%. The property sells on March 1, 2026 for $1,000,000 with a $400,000 first mortgage. Total adjusted basis is $200,000, allocated pro rata. The co-owners want to exchange into a Charlotte mixed-use building priced at $1,500,000 with $700,000 of new financing. Each co-owner maintains the same percentage ownership in the replacement.
| Line | Owner A (50%) | Owner B (30%) | Owner C (20%) | Total |
|---|---|---|---|---|
| Relinquished property allocated value | $500,000 | $300,000 | $200,000 | $1,000,000 |
| Allocated mortgage payoff | $200,000 | $120,000 | $80,000 | $400,000 |
| Allocated adjusted basis | $100,000 | $60,000 | $40,000 | $200,000 |
| Allocated realized gain | $400,000 | $240,000 | $160,000 | $800,000 |
| Net cash to QI (after payoff) | $300,000 | $180,000 | $120,000 | $600,000 |
| Replacement property allocated value | $750,000 | $450,000 | $300,000 | $1,500,000 |
| Allocated new mortgage assumed | $350,000 | $210,000 | $140,000 | $700,000 |
| Cash needed at replacement closing | $400,000 | $240,000 | $160,000 | $800,000 |
| Surplus cash to bring to closing (taxpayer contribution) | $100,000 | $60,000 | $40,000 | $200,000 |
| Boot received (cash, mortgage relief net) | $0 | $0 | $0 | $0 |
| Gain recognized | $0 | $0 | $0 | $0 |
| Gain deferred | $400,000 | $240,000 | $160,000 | $800,000 |
| New adjusted basis in replacement (cost – deferred gain) | $350,000 | $210,000 | $140,000 | $700,000 |
Each co-owner reports the exchange on their own Form 8824 instructions attached to Form 1040. Each co-owner needs their own QI agreement, but in practice a single institutional QI such as IPX1031 or Asset Preservation handles the entire deal under a multi-taxpayer master agreement. The new basis in the replacement is computed under IRC Section 1031(d) as the basis of the relinquished property plus boot given, minus boot received, plus gain recognized. In this clean example each owner brought additional cash equal to their pro rata share of the value-up ($1.5M replacement minus $1M relinquished = $500,000 total, allocated $250,000/$150,000/$100,000) less the financing increase ($300,000 net new debt allocated $150,000/$90,000/$60,000), so taxpayer cash contributions are $100,000/$60,000/$40,000. Net mortgage change is positive (more debt on replacement) so no mortgage boot is received. Net cash change is positive (more cash going in) so no cash boot is received. Result: 100% deferral.
Variant: Owner C wants to exit instead of exchanging. C is paid out at closing and recognizes her full $160,000 gain at 2026 long-term capital-gain rates plus depreciation recapture under IRC Section 1250. Owners A and B exchange their 50% and 30% TIC interests separately; the QI receives only the A and B proceeds. The replacement purchase is restructured for two owners or A and B find a new third TIC partner during the 45-day window. Common when one owner has different liquidity or estate-planning needs.
Drop-and-Swap and Swap-and-Drop: Breaking Partnerships Before or After Exchange
The drop-and-swap is the canonical workaround for the IRC Section 1031(a)(2)(D) partnership-interest exclusion. The partnership distributes undivided TIC interests under IRC Section 731. The TIC operating agreement must comply with Rev. Proc. 2002-22 (no more than 35 owners, unanimous-consent, pro rata economics). After distribution each former partner does an independent 1031 exchange.
The IRS challenges drop-and-swaps on two theories: (1) step-transaction under Court Holding Co., 324 U.S. 331 (1945) collapses the distribution and exchange into a partnership-level sale plus partner-level cash distribution; (2) the “held for investment” requirement of IRC Section 1031(a)(1) argues the former partner did not hold for investment because she received the TIC interest solely to facilitate the exchange. Revenue Ruling 75-292 took the IRS position; the Ninth Circuit pushed back in Magneson, Bolker, and Maloney v. Commissioner, 93 T.C. 89 (1989), and Mason v. Commissioner, T.C. Memo. 1988-273 all rejected the IRS attack where independent investment intent was documented.
Swap-and-drop reverses the sequence: the partnership exchanges at the entity level, then distributes the replacement as TIC interests post-close. Step-transaction risk shifts to the back end; Bolker is the cleanest authority. Best-practice timing per a Sullivan & Cromwell client alert on partnership 1031 sequencing: at least 12 months between the distribution and exchange closing for drop-and-swap (24 months ideal), and 12 months between the exchange closing and post-exchange distribution for swap-and-drop, with contemporaneous documentation of independent investment intent.
Delaware Statutory Trusts and Tenancy-in-Common as Replacement-Side Vehicles
Many multi-owner exchanges use DST and TIC structures on the replacement side to solve the 45-day identification problem. The sponsor market includes Inland Real Estate Group (and affiliate Inland Private Capital Corp), JLL Income Property Trust, Capital Square 1031, ExchangeRight, Cantor Fitzgerald (Rodin), Hines Securities, Bluerock, Passco Companies, Four Springs Capital Trust, and Cove Capital Investments. Sponsor fees typically run 6-8% offering loads, 1-1.5% annual asset-management, and 1-2% disposition.
When co-owners cannot agree on a single replacement, each identifies her own DST or TIC interest within her 45-day window. Seven-deadly-sins compliance of the DST sponsor is the diligence priority: request offering memorandum, trust agreement, property-management agreement, and prior-offering track record. Triple-net institutional tenants (Walgreens, FedEx, Amazon distribution, Dollar General) make seven-sins compliance easier. Minimums typically run $25,000 to $100,000. The combined 1031-into-DST then DST-to-UPREIT sequence under IRC Section 721 (after a 24-month hold) has become the dominant institutional multi-owner exit pattern, providing final-exit liquidity through eventual sale of REIT operating partnership units.
Related-Party Rules Under IRC Section 1031(f): The Trap for Family TICs
IRC Section 1031(f), enacted in 1989, treats an exchange between related parties as taxable if either party disposes of the exchanged property within two years. “Related party” is defined by reference to IRC Section 267(b) (family members including siblings, spouse, ancestors, lineal descendants; certain trusts and entities) and IRC Section 707(b) (partnerships and partners owning more than 50% of capital or profits). The two-year clock runs from the date of the exchange.
For multi-owner deals the related-party trap snares family TICs and partnerships among related parties. Teruya Brothers, Ltd. v. Commissioner, 580 F.3d 1038 (9th Cir. 2009) held that an exchange between a corporation and its 62.5% owned subsidiary violated Section 1031(f) and the entire deferral was lost. Ocmulgee Fields, Inc. v. Commissioner, 613 F.3d 1360 (11th Cir. 2010) reached a similar result. The IRS reads Section 1031(f) expansively to capture any exchange where the related party ends up with the cash, even if intermediated through a QI.
Two exceptions in Section 1031(f)(2) save some deals: an exchange where the related party also continues to hold the exchanged property for at least two years, and an exchange that has as one of its principal purposes a non-tax purpose other than the avoidance of federal income tax. The second exception is a facts-and-circumstances test that the IRS reads narrowly. The safe practical rule on multi-owner deals among family members or related entities: do not use a related party as either the buyer of the relinquished property or the seller of the replacement property. Use unrelated third parties on both sides.
5 Common 1031 Mistakes in Multi-Owner Deals
1. Missed deadlines. The 45-day identification deadline and the 180-day exchange deadline are absolute and have been upheld in every reported decision (see U.S. Tax Court memorandum opinions on improper drop-and-swap timing). Knight v. Commissioner, T.C. Memo. 1992-710. Christensen v. Commissioner, T.C. Memo. 1998-273. Dobrich v. Commissioner, T.C. Memo. 1997-477. In multi-owner deals coordination compounds the risk: one co-owner identifies on Day 44, another forgets and identifies on Day 46, only the first qualifies. Use a written checklist with all co-owner deadlines, send weekly reminders, and require a Day-30 status call.
2. Related-party violations. Family TICs that exchange with a parent, sibling, or controlled entity within two years of the exchange lose deferral under IRC Section 1031(f). The fix is to use unrelated third parties on both sides and document the non-tax business purpose if any related party is involved.
3. Taxpayer-mismatch (same-taxpayer rule). The most common partnership-deal failure: the partnership sells, the partners try to exchange individually. Either the partnership exchanges as one taxpayer (and the partners cannot pull cash), or the partners do a drop-and-swap with adequate timing. There is no middle ground.
4. Partial-exchange errors. One co-owner takes cash, the others exchange. The cash-taker recognizes gain on her proceeds, the exchangers defer. This works fine if structured as a TIC. It fails if the partnership tries to do a “partial exchange” by buying a smaller replacement for some partners and distributing cash to others without a proper drop-and-swap. The IRS will recharacterize the entire transaction as a partnership-level sale plus distributions.
5. QI bonding gaps. The 2008-2010 QI failures (LandAmerica Exchange Services, 1031 Tax Group LLC) cost exchangers tens of millions of dollars when QIs misappropriated or lost segregated funds. For multi-owner deals where each co-owner has hundreds of thousands at risk in the QI’s escrow, demand evidence of segregated qualified escrow accounts under Treas. Reg. 1.1031(k)-1(g)(3), separate FDIC insurance, fidelity-bond coverage with each co-owner as a named insured, and an SSAE 18 SOC 1 Type 2 internal-controls audit by an independent firm. The cost is small relative to the exposure; the FEA Certified Exchange Specialist directory is the starting point for vetting.
TLDR and 7 Decision-Stage Takeaways
- Structure first, sell second. Pick TIC, partnership-level exchange, or drop-and-swap before signing the listing agreement. Reverse-engineering structure after a buyer is found is where deals fail.
- TIC is the cleanest multi-owner structure if Rev. Proc. 2002-22 conditions are met. Each co-owner exchanges separately, picks her own replacement, files her own Form 8824, controls her own outcome.
- Partnership interests cannot be exchanged. IRC Section 1031(a)(2)(D). If you hold through a partnership or multi-member LLC, the only options are entity-level exchange or drop-and-swap with adequate timing (12 to 24 months ideally).
- The 45-day and 180-day clocks are absolute. No extensions except presidentially declared disasters under Rev. Proc. 2018-58. Build a coordinated calendar for all co-owners with weekly checkpoints.
- QI selection is risk management. Demand segregated escrow, fidelity bonding with each co-owner named, SSAE 18 SOC 1 Type 2 audit, and contractual prohibition on rehypothecation of exchange funds.
- Model boot allocation before closing. Cash boot and mortgage boot in multi-owner deals can hit one co-owner disproportionately when partnership debt allocations under IRC Section 752 are uneven. An Excel model showing each co-owner’s allocated boot avoids March surprises.
- State conformity is the silent killer. California’s clawback under Cal. Rev. & Tax Code Section 18032 means a California-source 1031 deferral follows the taxpayer indefinitely. Pennsylvania has no 1031 conformity for personal income tax. Plan state tax separately from federal, especially for cross-border multi-owner deals.
