Let me do my best to help clear things up around e-file:

2015 and all prior year e-file

• closed, these returns must be paper filed

2016 

• Business TBA (an in-product alert will be posted once we go live)
• Individual January 28

2017

• Business TBA (an in-product alert will be posted once we go live)
• Individual January 28

2018

• Business January 22
• Individual January 28

Business e-file returns transmitted via 2017 and 2016 Lacerte will not be turned away instead, they will be held until e-file re-opens for TY16 and TY17 filings. The IRS business e-file opened January 8, 2019.  An in-product alert will be posted once business e-file goes live in-product.  All acknowledgments will be updated at this time.
