After you file

@MarilynG1 

Thank you. I understand the conditions as to when you have to mail the statements (when there are adjustments and summary format was used) but what I am looking to find out is what is done in his scenario where he had over 500 to 800+ pages in transactions with and without adjustments. Since the summary format was selected, one has to mail all 500 to 800+ pages with the 8453? 

 

In that sense, what in specific has to be mailed?:

   - All pages of 1099B (which was sent to the IRS by the broker)?

   - or all pages of Year-End Summary (not sent to IRS by the broker and has the same large number of transactions pages as the 1099B )

   - or both/1099B and Year-End Summary which is the entire tax package received from the broker? 

 

Any help will be appreciated.
