The IRS will be shutting down their 1040 Modernized E-file system on the
morning of November 30, 2016. This shutdown will last until the 2017 filing
season opens in January 2017.
If you have any 2015 federal or state tax returns
that you wish to file as a current year return, you should transmit them by
November 29, 2016 in order ensure that you are able to get acknowledgements back
before the IRS system is shutdown on November 30, 2016.
