Lois has it right. Internal Revenue Code sections 7508 and 7508A provide for the automatic postponement of certain deadlines under the Code by reason of a presidentially declared disaster. IRS Rev. Proc. 2018-58 lists the tax deadlines that will be automatically postponed under these Code sections; Section 8.13 of the Revenue Procedure provides that the filing date of the IRS Form 5498-SA is one of the tax deadlines that is automatically postponed pursuant to Code section 7508 and 7508A. IRS Notice 2020-23 provides that, due to the COVID-19 pandemic, everyone is under a presidentially declared disaster, so any person that has to meet a deadline under the Code between April 1, 2020 and July 15, 2020 has until July 15, 2020 to take the action to meet that deadline. Consequently, IRS Form 5498-SA that was required to be filed by May 31, 2020, will now have to be filed by July 15, 2020.
