I am working in a small software company. I receive a salary of ₹30,000 in cash. I got selected in two companies, both of which are asking for a bank statement, but I don't have one because I am paid in cash. They are asking for some payment proof like a cash payment voucher. I used to sign the voucher, but I heard that the receiver should sign on the cash voucher across the stamp. However, I did not sign on the stamp; I signed on the cash voucher. I have one more problem: they do not deduct TDS. Can you please provide me with a solution for this?
