The IRS has issued Notice 2020-23, extending a variety of deadlines, including Section 1031 deadlines. This Notice would extend any 45-day or 180-day deadline that occurs between April 1 and July 15, to July 15, 2020.
The Notice is confusing, because it is not written like the typical Disaster Relief Notices, and does not explicitly reference Section 17 of Rev Proc 2018-58. Without the specific reference to Section 17, current prevailing thought is that the 120 day extension does not apply. Thus, a taxpayer with a 45th day falling on May 16, would receive an extension of the identification deadline to July 15. But that same taxpayer would not receive an extension to the 180 day deadline because it falls after July 15.
GAC leadership is working on a request for clarification.
Note also that the deadline for Opportunity Zone investment has also been extended.
