The IRS Modernized e-File (MeF) Production and Assurance Testing System (ATS) environments are currently unavailable due to unscheduled maintenance. A follow-up Quick Alert will be issued when both environments are fully operational.

Wolters Kluwer will continue to accept transmitted returns into our Electronic Filing Centers  and will send them to IRS once they are back online. If you have submitted an e-file,  please note that acknowledgements from the IRS (such as "Transmitted to Agency," "Accepted/Rejected") will not be returned until the MeF Production environment is back up and running.

For source information, please monitor the MeF Operational Status page . We will update you as soon as we have confirmation from the IRS.
