Do I need any tax paid receipts while H1B stamping

Hi

I have received the H1-B petition approval and I will soon be attending H1-B visa interview. 



So I have couple of questions. I have been to US on L1 visa in past, so I have SSN, and I remember that the salary I used to receive was after tax.  



1. Do I need to have or carry any tax paid receipts, as I said I remember my salary was after tax there.



2. Is there a way to get the tax paid receipts using SSN




Appreciate your help.
