IRS News: Modernized e-File (MeF) Extended Maintenance Window

The IRS has announced an upcoming extended maintenance window for their MeF Production and Testing Systems on Saturday, September 23, 2023, from 12:01 am ET until Sunday, September 24, 2023 5:00 pm ET.

Please monitor the MeF Operational Status page for any future updates.

During this time you will be able to continue transmitting your returns to our Electronic Filing Center (EFC); however, we will be unable to send to the IRS or retrieve acknowledgements (acks) until the MeF system is back online.
