1040 Modernized e-File (MeF) Production Shutdown: What You Need to Know

The 1040 Modernized e-File (MeF) Production system will be temporarily shutting down for scheduled maintenance. The shutdown is set to commence on Saturday, November 18, 2023, at precisely 11:59 p.m. Eastern time. This is a necessary step to prepare the system for the forthcoming Tax Year 2023 Filing Season.

Services Affected by the Shutdown

It’s important to note that the shutdown will only affect the “Send Submissions” for 1040 (both State and Federal). All other services such as “Get Acks” and all state services will be unaffected by the shutdown. Users should be able to continue to use these services without interruption.

Shutdown Deadlines

For transmitters, the deadline for transmitting 1040 Submissions (State & Federal) is also set for 11:59 p.m. Eastern time on Saturday, November 18, 2023.

Business Returns Unaffected

Business (BMF) returns will not be impacted by this IMF Production Shutdown schedule. The BMF Production Shutdown schedule will be communicated separately via a QuickAlerts bulletin. This bulletin will outline the exact timeframes and will be issued in early December. The times will also be posted on the MeF Operational Status page.
