The IRS has announced an upcoming extended maintenance window for their MeF Production and Testing Systems on Sunday, March 19, 2023, from 12:01 am. until 10:00 am. Eastern time.
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.
