I have previously done my 90 day reporting by mail or in person. I have read through the 90 day report section in the popular post topics on this site but I am a little confused as to the window of time to do an online 90 day report. some posts seem to indicate that you can only submit a 90 day report online when you are between 15 to 7 days out from your due date. Other posts seem to indicate that you can do an online 90 day report right up to your due date. Can you please clarify what is the correct window of time
