I'm Mursheed Alam, and I'm working as a contractor in an MNC. Actually, I'm paying 10% of my total salary every month for T.D.S., but I didn't receive any T.D.S. slip/challan. I joined my company on 1st July 2013, and from July until now, I have been paying 10% of my total salary every month continuously. Can I show my investments to reduce my tax? Please provide me with guidance because I still don't have any type of T.D.S. challan.
