Identification
Identification is the act of describing potential replacement properties in writing as a part of a 1031 exchange. Identification must be completed within 45 days of the sale of your relinquished property. There are guidelines for properly identifying property;
Section 1031 allows taxpayers 45 days from the time their first property is sold to identify potential replacement property. The IRS has set guidelines on the number and value of identified properties. Failure to follow these guidelines can result in a failed exchange :
If the taxpayer purchases their replacement property before the 45 day period is up, the act of purchasing the property counts as identification of that property.
How to Submit Your Identification
The best way to identify property is in writing to your accommodator. Most accommodators will provide their clients a form to fill out and return. Although there are other acceptable ways to submit your identification, this is the most reliable.
