A 1031 exchange is a powerful tool that can help investors defer taxes when they sell one investment property and buy another. However, there are some common mistakes that investors sometimes make during the process that can cost them time and money. In this article, we will discuss some of the most common mistakes and how to avoid them in a 1031 Exchange.
Mistake #1: Not using a 1031 Exchange Qualified Intermediary
A Qualified Intermediary (QI) is a third-party facilitator that through a series of assignments acts as the party to complete the exchange with the Exchanger. By virtue of these assignments, title to the Relinquished Party passes through the QI to the Buyer, and title to the Replacement Property passes through the QI to the Exchanger. Title does not actually vest in the QI, saving a legal step, and in many states, additional transfer taxes. The QI ensures a valid 1031 exchange by properly structuring the exchange per IRC §1031, preparing all necessary exchange documents, and monitoring the exchange for compliance throughout the process. Failure to use a QI can result in missteps causing the disqualification of the exchange and the loss of tax deferral benefits.
Mistake #2: Waiting Too Long to Set Up the Exchange
One of the most critical, and most overlooked, mistakes is waiting too long to involve a Qualified Intermediary (QI). A 1031 Exchange must be established before the closing of the property for sale, the Relinquished Property. If the exchange isn’t set up in advance, the transaction becomes a taxable sale.
How to avoid it: Engage a QI as soon as the Relinquished Property is listed or under contract. Early involvement ensures proper structuring, inclusion of exchange cooperation language in contracts, and helps avoid constructive receipt of funds.
Mistake #3: Not understanding the 1031 Exchange timeline
The IRS has specific rules and timelines that must be followed in a 1031 Exchange. Investors have 45 days from the sale of their Relinquished Property to identify potential Replacement Properties and 180 days to complete the purchase of one or more of those identified Replacement Properties. Failure to meet either of these deadlines will result in the disqualification of the 1031 Exchange, meaning that the investor will be responsible for paying the associated taxes realized from the sale of the Relinquished Property.
How to avoid it: Investors should begin evaluating Replacement Property options before selling their Relinquished Property and consider identifying backup options following one of the three identification rules.
Mistake #4: Not properly identifying a Replacement Property
Investors must follow strict identification rules when selecting Replacement Properties in a 1031 Exchange. The potential Replacement Property(ies) has to be identified within 45 days of the sale of their Relinquished Property, and it must follow one of three identification rules:
- The Three-Property Rule
- The 200% Rule
- The 95% Rule
Failure to properly identify Replacement Properties can result in the disqualification of the exchange.
How to avoid it: Work closely with your QI and other advisors, consider identifying multiple backup properties in case your primary option falls through.
Mistake #5: Receiving “Boot”
“Boot” refers to any non-like-kind value received as part of a 1031 Exchange, and it is one of the most common ways investors inadvertently trigger a taxable event. Boot can take several forms, including cash received from the transaction, a reduction in Replacement Property mortgage debt, often called mortgage boot, or the receipt of other non-like-kind property. When boot is received, it is generally considered taxable income, which can reduce or eliminate the intended tax deferral benefits of the exchange.
How to avoid it: Investors should aim to fully reinvest all net proceeds from the sale into Replacement Property and ensure that any debt paid off on the Relinquished Property is replaced with equal or greater debt on the new acquisition. In some cases, acquiring multiple Replacement Properties can help meet these requirements and preserve full tax deferral.
Mistake #6: Ownership Structuring Issues
A key rule in 1031 Exchanges is that the same taxpayer who sells the Relinquished Property must also acquire the Replacement Property—often referred to as the “Same Taxpayer” requirement. In simple terms, the same person or entity on the title to the Relinquished Property must also take title to the Replacement Property. While this may sound straightforward, it can become complex in practice, particularly when ownership involves partnerships, married couples, community property state rules, trusts, or entities such as LLCs.
How to avoid it: Plan ownership structure well in advance. Consult with your QI and tax advisor if multiple parties are involved or if ownership changes are being considered.
Mistake #7: Mixing personal and business property
A 1031 Exchange is only applicable to property used for investment or business. It cannot be used for personal property, such as a primary residence. Mixing personal and business property can result in the disqualification of the exchange.
How to avoid it: Ensure both Relinquished and Replacement Properties meet IRS requirements and that intent to hold for investment is well documented (e.g., leases, rental listings, tax filings).
Mistake #8: Acquiring Property from a Related Party
Transactions involving related parties—such as family members, trusts or corporations controlled by the same Taxpayer are heavily scrutinized by the IRS. The rules are strict because the IRS wants to prevent Taxpayers from using related-party exchanges to manipulate tax outcomes without genuine reinvestment.
How to avoid it: Understand who is considered a Related Party in regards of a 1031 Exchange, some examples might be Family members (parents, children, siblings, spouses), entities where the Taxpayer owns more than 50%, partnerships and their partners, corporations and majority shareholders. There are ways to acquire a property from a related party, but strict rules must be followed to make a successful exchange.
Mistake #9: Partnership “Drop & Swap” Done Too Close to Closing
In partnership scenarios, some owners may want to cash out while others want to complete a 1031 Exchange. A common strategy is a “drop & swap,” where the partnership first converts its ownership interests into individual tenant-in-common (TIC) interests, allowing individual partners to exchange their share of the property. However, doing this too close to the sale can raise IRS concerns, as the transaction may appear to be a disguised sale rather than a bona fide exchange. Timing and proper documentation are critical to ensure the strategy is recognized for tax deferral purposes.
How to avoid it: Plan well in advance. Sudden ownership changes may indicate lack of investment intent and risk disqualification. Work with experienced advisors when structuring these transactions.
Mistake #10: Not consulting with a tax professional
A 1031 exchange is, at its core, a tax deferral strategy, so in addition to utilizing a QI the Exchanger should consult with a tax professional. Attempting to navigate it without guidance from a CPA or qualified tax advisor can lead to costly missteps. A tax professional can help you understand how the exchange fits into your broader financial picture, ensure it’s reported correctly, and identify potential tax consequences, including depreciation recapture and any “boot” received.
How to avoid it: The rules and regulations surrounding 1031 Exchanges can be complex, making it essential to work with a coordinated team of professionals. This typically includes a Qualified Intermediary (QI), a tax professional, and ideally a financial advisor. Together, they can help ensure all requirements are met, risks are minimized, and you’re positioned to receive the full benefit of the exchange.
A 1031 Exchange can be an effective way to defer taxes on investment properties. However, it is important to understand the rules and requirements of the process to avoid common mistakes that will result in the disqualification of the exchange. Most of these mistakes can be easily avoided by planning early, working with a reputable QI, and consulting with a tax professional.
