I read a note that "An electronically transmitted return will not be considered complete until a Form 8453 is received by the IRS." So I decided to mail the form with only the last page of my 1099-B which shows the Totals for Short term covered 1d, 1e, 1g and the 1st page of 1099-b which shows Summary of Form1099-B. IF they don't like it and require the full 300 pgs, I will send it in when they ask for it but i think this is a little ridiculous and tt should allow pdf attachments like tax act's attachment mgr which allows 3MB pdf;s specifically for 8453. Thanks for all your responses!!
