According to the Fresno IRS Service Center, around 40,000 to 50,000 extensions filed using Form 4868 were wrongly denied at the Fresno IRS campus. Most of the forms were transmitted in bulk via paid preparers. The IRS is now notifying impacted taxpayers and preparers that the extension(s) is allowed and that they should ignore the previous communication.
If your extension was denied, and it was filed in Fresno, do nothing until July. Then if you feel it was wrongly denied, and you have not heard from the IRS, you should request a reconsideration using the process noted in the denial letter.
The error apparently stems from “human error” is misstamping the incoming Form 4868s.
