Do I need any tax paid receipts while H1B stamping


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.
