There is a TCS credit in my account due to scrape sold by ABC. The fact is that I have not made any purchases from ABC during the previous Years. Assessing officer has made addition of Rs. 10 lacs (Cost of scrape sold) in my total income while passing the order u/s. 143(3) without considering the fact that I have filed an affidavite rejecting the same purchases. What to do and on what grounds appeal can be made?
