What is the 1031 Exchange Rule?
Under Section 1031 of the Internal Revenue Code (IRC), a real estate investor can defer paying capital gains taxes on an investment property if they reinvest the proceeds into a "like-kind" property of equal or greater value.
Critical Timelines Explained
- Day 0 (Sale Date): The day you close on the sale of your old property.
- Day 45 (Identification Period): You must submit a list of potential replacement properties to your Qualified Intermediary. This is a strict deadline.
- Day 180 (Exchange Period): You must complete the purchase of the new property. This timeline runs concurrently with the 45-day period.
