Will a C Corporation extension for 2017 fiscal year return due January 15th, 2019 be transmitted to the IRS by the due date?

Did I miss something?  Where did you get January 22nd from?

The last I heard, they started yesterday.

The Alert in the 2018 program indicates that IRS opened 1/8/2019 but Business efiling by Intuit will commence on 1/22/2019.  I didn't see the prior year filing indication and no acceptance notices received yet.

Interesting.  ProSeries does not have that alert (yet).  That link I gave you says ProSeries too.

I wonder if Lacerte is waiting for a while but ProSeries is sending them?  Or maybe ProSeries is just late for getting the change.   :-)


EDIT:  Now that I think about it, the 22nd may apply to 2018 tax returns, but the 8th applies to older tax returns.

Here is the FAQ from Lacerte:
Can I e-file Prior Year Business Returns?
You can e-file the current year and two prior years for Business returns (after the IRS opens e-file for the current tax season).

Business Filing Example: When the IRS opens the Business e-file servers for TY18 in early 2019, you will be able to e-file 2017 and 2016 Tax Returns. Once the IRS opens the Individual e-file servers for TY18, Lacerte will open both TY18 Business and Individual e-file.  If a return is submitted after its applicable due date, it will be considered late.  Once the IRS shuts down the MeF system in November 2019 for Individual returns, 2016 tax returns can no longer be transmitted.  

Looks like IRS will accept old returns starting yesterday but Lacerte is waiting until the 2018 year filing date. You would think that there would be a simple Lacerte switch to turn on to be able to e-file the business returns now....

Here is the chart on opening dates
                                                                                                         IRS Open Date   Intuit ProConnect Lacerte Open Date
Filing Season Opens for Modernized e-file Business Returns         January 8, 2019       January 22, 2019
Filing Season Opens for Modernized e-file Individual Returns       January 28, 2019       January 28, 2019

Looks like Mr. Yote was correct - paper it should be.

Interesting.  So the announcement for ProSeries says "January 8th for business returns. We will be once again be transmitting prior year business returns at this time".

Does that mean you can e-file them with ProSeries, but not with Lacerte?

Intuit has to admit the above FAQ is clear as mud. Maybe @IntuitAlicia can get the scoop from the big dogs?

FWIW, I called Lacerte yesterday, 1/9/2019, about a FY2017 January 15 due date e-file that was not sent to the IRS.  The gentleman told me it will be sent to the IRS on January 16, 2019.  The January 8 date is not accurate as a reopen date anymore.
Additional info***My e-file was sent and received by the IRS today, 1/10/2019.
