What Documentation Do You Need for a 1031 Exchange?

1031 National Services

While taxpayers who conduct 1031 exchanges can achieve significant tax savings, they must be able to prove that their exchanges qualify for indefinite tax deferral under the Internal Revenue Code. Improperly claiming eligibility for indefinite tax deferral can lead to scrutiny from the Internal Revenue Service (IRS)—and this scrutiny can lead to substantial liability for back taxes, interest, and penalties. As a result, a proactive approach to compliance is essential, and this involves working with a 1031 exchange facilitator who can assist with generating all necessary documentation.

Essential Documentation in a 1031 Exchange

Taxpayers will need several forms of documentation to conduct a 1031 exchange (and ensure that they are prepared to demonstrate compliance to the IRS if necessary). While not exhaustive, the following is a list of some of the key forms of documentation that will be required:

Exchange Agreement

An exchange agreement is a contract between a taxpayer and the taxpayer’s 1031 exchange facilitator (or qualified intermediary). In a 1031 exchange, an exchange facilitator plays an essential role in preserving the taxpayer’s eligibility for indefinite tax deferral. In the event of an IRS audit or investigation, being able to show that the taxpayer engaged a 1031 exchange facilitator as required can be a key step toward avoiding unwarranted tax liability (among other adverse consequences).

“Identification” of the Replacement Property

Most 1031 exchanges are delayed exchanges. These involve conducting two separate transactions in sequence—(i) selling the taxpayer’s “relinquished” property, then (ii) using the proceeds from this sale to purchase the taxpayer’s “replacement” property.

When conducting a delayed exchange, formally “identifying” the replacement property is a key step in the process. As a result, the taxpayer’s documentation of this “identification” is also key. There are specific requirements for identifying a replacement property for a 1031 exchange, and an experienced 1031 exchange facilitator can assist in meeting them.

Purchase and Sale Agreements

As with all types of real estate transactions, purchase and sale agreements are essential for establishing the terms of the disposition and acquisition involved in a 1031 exchange. However, when conducting a 1031 exchange, it is important not to rely on the same form agreements that would typically be used. Purchase and sale agreements used for 1031 exchanges should include terms specific to the exchange process and ensure that the taxpayer’s 1031 exchange facilitator plays an appropriate role at all stages.

Notice of Assignment

To allow a 1031 exchange facilitator to do what is necessary, a taxpayer must sign a notice of assignment and provide copies to all appropriate parties (i.e., the seller and any lenders involved). This is a formal legal document that assigns certain rights to the exchange facilitator, which is required so that the exchange facilitator can hold the taxpayer’s funds in trust in a delayed exchange or “park” the taxpayer’s replacement property in a reverse exchange.

Closing Statement (or Settlement Statement)

A closing statement (or settlement statement) is used to prove that the funds involved in a 1031 exchange have exchanged hands at the appropriate time. Timing is a key factor in 1031 exchanges, and if a taxpayer receives any funds or other property too soon, this can immediately preclude the taxpayer from claiming indefinite tax deferral.

IRS Form 8824

Taxpayers who have completed a 1031 exchange during the tax year must file IRS Form 8824 (Like-Kind Exchanges) by the due date for their federal income tax return. Carefully following the instructions for IRS Form 8824 is essential, and taxpayers should seek advice from their 1031 exchange facilitator, accountant, or tax counsel as necessary.

Since even minor technical issues with IRS Form 8824 can raise red flags during an automated review of a taxpayer’s return, taxpayers will want to ensure that they avoid any oversights or other mistakes that could have been avoided. Even if a taxpayer’s 1031 exchange is otherwise fully compliant with the Internal Revenue Code, facing scrutiny from the IRS can lead to additional costs that could have been avoided as well.
