What Are the Common Misunderstandings About 200-37 and Related Tax Codes?

Written by The Realized Team | Feb 22, 2026

Code 200-37 or Revenue Procedure 2000-37 created the safe harbor guidelines for 1031 reverse exchanges. While the rules are clear, many myths about the 200-37 tax code have emerged over the years, stemming from oversimplified explanations or outdated interpretations. Some are harmless, while others could lead to major issues that may result in the loss of your tax-deferral status.

Realized 1031 shares these common misunderstandings about Revenue Procedure 2000-37 to demystify the false beliefs and shed light on the nuances. Let’s take a closer look.

Myth 1: Revenue Procedure 2000-37 Is Law

One of the most prevalent misconceptions about reverse 1031 exchanges is that Code 200-37 is the law. Many believe that it’s a statute enacted by Congress and signed by the sitting president. It is not. Revenue Procedure 2000-37 is an administrative guidance issued by the IRS, not a federal law.

The reason why Code 200-37 exists is to create safe harbor language that structures reverse exchanges. Under these conditions, the IRS won’t challenge the exchange even though it didn’t follow the traditional principles outlined by Section 1031. The revenue procedure is simply a way to explain how the IRS will interpret and enforce these existing rules for specific situations.

Myth 2: Code 200-37 Guarantees 1031 Eligibility

Some investors believe that by simply following the guidelines of Revenue Procedure 2000-37, a reverse exchange is automatically qualified for 1031 Exchange tax deferral. This isn’t true. The safe harbor only covers property parking and ownership rules, ensuring that you don’t hold title to both properties at the same time.

You still need to follow the other exchange requirements outlined by Section 1031. Otherwise, the transaction won’t qualify for tax deferral. These include the following.

  • Like-kind property requirements
  • Proper identification of replacement property
  • Holding property for investment or business use
  • Compliance with timing rules
  • Reinvestment of all proceeds

Myth 3: The 180-Day Period Is Flexible

Code 200-37 limits the accommodation period — or how long the exchange accommodation titleholder (EAT) can “own” one of the properties in the exchange — to 180 days. Some investors may look at this deadline as a flexible guideline, but it’s a hard limit.

You cannot ask for extensions for financing delays, construction overruns, or more favorable market conditions. Otherwise, the exchange may no longer be eligible. What you’ll want to remember is that the 180-day accommodation timeframe is the equivalent of the 180-day deadline in a traditional exchange.

Myth 4: Revenue Procedure 2004-51 Replaced 2000-37

One of the more concerning misconceptions about reverse 1031 exchanges is the belief that Revenue Procedure 2004-51 supersedes or replaces Code 200-37. The more accurate interpretation is that the former simply modified the initial structure for reverse exchanges.

Revenue Procedure 2004-51 clarified what doesn’t qualify for safe harbor. More specifically, the updated guidelines restricted the parking of property you already owned within the 180-day period. This mechanism prevented a self-exchange, which was initially possible before 2004-51.

Myth 5: Any Third Party Can Serve as an EAT

There’s another possibly detrimental belief surrounding Code 200-37: any neutral party can serve as an EAT. Some investors believe that a friend, an attorney they know, or an LLC they control will be enough to hold the title. This stems from the wording that the EAT must be simply “independent.”

However, we mustn’t forget that in a 1031 Exchange, related parties aren’t allowed to become involved. These include family, financial professionals you’ve had fiduciary relationships with, or business entities where you have significant control. This requirement supersedes 200-37. Having these related parties as EAT could invalidate the exchange and make you liable to a major tax hit.

Myth 6: Revenue Procedure 2000-37 Covers All Complex Exchanges

Some investors might assume that Code 200-37 can serve as guidelines for all complex exchange variations. However, the structure only provides a safe harbor for reverse exchanges. The scope is narrow and highly specific. Instead, you must refer to other rulings, procedures, or broader Section 1031 case laws for guidance. One example is Revenue Procedure 2002-22, which is the guideline for exchanges involving tenancy-in-common (TIC) interests.

Summing Up: Reverse 1031 Exchange Safe Harbor Misunderstandings

When learning about the guidelines set by Revenue Procedure 2000-37, you may encounter myths and misconceptions regarding the timelines, 1031 eligibility, and other aspects of the exchange. These misunderstandings are unavoidable because of the complex nature of the reverse exchange, but with the insights we shared above and the guidance of a tax professional, you can gain a deeper understanding that shields you from problematic mistakes.
