Of course, if you do wish to defer that final 4th Qtr payment , and use the option to pay and file your tax return by 1 Feb.....you may be caught in Catch-22 and should not plan on doing that. (yeah, just an opinion....but what could go wrong)
1) You must file a complete tax return, with all data entered...including investment 1099-B/8949 forms that may not come out until mid-Feb.
2) The software may not have all the forms finalized to enable you to file....finger point all you want, but the IRS doesn't care whose fault it is..
3) No one has any idea whether the IRS will start accepting any tax files by then....they might extend the 1 Feb deadline for that situation...they may not.
