Understanding reverse and property improvement exchanges outside the IRS safe harbor

Real estate investors have long relied on Section 1031 of the tax code to defer taxes when trading one investment property for another. For most exchanges, the process is straightforward: sell first, buy second. But real deals rarely follow a perfect script. Sometimes the ideal replacement property becomes available before you can sell your current one. Other times, the property you want needs construction or renovation before it fits your investment goals.

These situations call for two more advanced structures: the reverse exchange and the property improvement exchange. Both can be powerful tools, and both raise important questions about how the Internal Revenue Service will treat them, especially when a deal falls outside the agency's established safe harbor.

Here’s a look at how these exchanges developed, what the safe harbor requires, and why a 2016 court decision continues to shape investor strategy today.

The evolution of Section 1031

Section 1031 has been part of the tax code since 1921. The concept behind it is simple: if you stay invested in like-kind property rather than cashing out, it makes sense to defer the tax rather than treat the transaction as a final sale. This idea, often described as continuity of investment, remains the foundation of the exchange today.

Over the decades, the rules grew more detailed. While many asset types once qualified, current law limits like-kind exchange treatment to real estate held for investment or business use.

In 1991, the Internal Revenue Service (IRS) issued regulations that created safe harbors to give taxpayers more certainty in standard deferred exchanges. Those rules addressed matters such as qualified intermediaries and escrow arrangements. However, they left two common scenarios unaddressed: exchanges where the investor needed to acquire the replacement property first, and exchanges where a portion of the proceeds funded construction or improvements. That gap set the stage for future guidance.

The safe harbor for reverse and improvement exchanges

The wait ended in 2000, when the IRS published Revenue Procedure 2000–37. This guidance established a dedicated safe harbor for reverse and construction or improvement exchanges, giving investors a clear framework to follow.

Two requirements sit at the center of this safe harbor:

• A third-party titleholder. The structure requires an exchange accommodation titleholder, often called an EAT, to hold, or 'park,' title to the property during the transaction.
   
• A 180-day limit. The parking arrangement must be completed within 180 days.

For many investors, this framework became the preferred path because it offered predictability and reduced tax risk.

How these deals worked before the safe harbor

Before 2000, investors who wanted to structure a reverse or improvement exchange had to look to case law for support. The guiding principle was that a title parking arrangement could work, but the accommodator needed to hold true 'benefits and burdens' of ownership. In other words, the third party had to function as a genuine owner, not a titleholder in name only.

Meeting that standard was difficult. It generally required:

• Real economic exposure, including the risk of gain or loss if the property's value changed
   
• Meaningful equity from the accommodator, often viewed as at least 5% of the total
   
• A lease back to the investor on genuine, arm's-length terms

Because these conditions were hard to satisfy in practice, the safe harbor represented a significant simplification. It largely replaced the demanding benefits and burdens test with a clearer, more workable process.

Structuring a deal outside the safe harbor

The 180-day limit works well for many transactions, but not all. New construction is the clearest example. Architectural plans, permits, lender requirements, contractor schedules, inspections and weather delays can easily push a project well beyond 180 days.

The IRS anticipated this challenge. Revenue Procedure 2000–37 included language stating that no adverse inference should be drawn simply because a parking transaction falls outside the safe harbor. In plain terms, operating outside the safe harbor does not automatically invalidate a deal. It only means the transaction does not receive the same built-in certainty.

That distinction mattered, but it came with a catch. For years, the only practical way to support a longer transaction was to return to the traditional benefits and burdens approach, the very standard that had proven so hard to meet.

The significance of the Bartell case

The landscape shifted in 2016 with the decision in Estate of George H. Bartell Jr. v. Commissioner.

The case involved an exchange tied to new construction, with a parking arrangement that lasted roughly 17 months, far longer than the safe harbor allows. What made it notable was the structure itself. Rather than building in the extensive economic risk associated with the benefits and burdens test, the arrangement relied on a third party simply holding title during the construction period.

The IRS challenged the reporting, arguing that the deal did not meet the historical requirements for a transaction outside the safe harbor. The court disagreed. After reviewing prior cases, it concluded that the case law primarily required a third party to hold title during construction, not to shoulder full ownership risk.

This ruling was a notable departure from what many practitioners expected, and it opened the door for more parking transactions structured along similar lines.

The IRS non-acquiescence and ongoing considerations

The IRS did not embrace the outcome. It filed a non-acquiescence, signaling that it disagreed with the decision and would not treat it as binding in other cases. As a practical matter, this means investors in other federal districts cannot automatically rely on the ruling as controlling law.

Even so, the years since 2016 tell an instructive story. Deals exceeding 180 days and structured under the Bartell model have become increasingly common, and there is no public evidence that the agency has disallowed the approach. For many investors and their advisors, that track record suggests these longer parking arrangements are workable, provided they are structured carefully.

Key takeaways for investors

Reverse and property improvement exchanges give investors valuable flexibility when a transaction does not fit the standard sell-first, buy-second model. As you evaluate these strategies, keep a few points in mind:

• A reverse exchange lets you secure a replacement property before selling your current one
   
• A property improvement exchange allows exchange proceeds to fund renovation or construction on the replacement property
   
• Revenue Procedure 2000–37 offers a safe harbor that many investors rely on, generally requiring a third-party titleholder and completion within 180 days
   
• Transactions outside the safe harbor remain possible, but they carry more uncertainty
   
• The Bartell decision made longer arrangements more viable in some situations, though the non-acquiescence means it is not universal protection

The difference between a successful structure and a costly misstep often comes down to the details. Because every transaction carries its own facts and its own risks, consult qualified tax and legal advisors who understand Section 1031, current case law and the specifics of your deal before moving forward.
