Tax Preparers: E-File Mandate


Early shutdown, on December 2, 2013, for corporate (512 & 512-S) Modernized e-File (MeF).

Oklahoma is migrating to a new operating system for income tax.  This has resulted in the need for an early shutdown of corporate MeF. The last day Oklahoma will retrieve returns from the IRS is Monday, December 2, 2013.  Any returns not retrieved, receipted and/or acknowledged by end of business day Monday, December 2nd will not be retrieved, receipted and/or acknowledged until the IRS opens for production in January 2014. 

Oklahoma corporate returns e-filed after the Oklahoma Tax Commission shutdown but before the IRS shutdown will be retrieved when the IRS opens for production in January, 2014.
