According to the provisions of TDS on salary under Section 192. TDS on salary should be deducted on payment basis not on due basis. But if anyone is going to deduct TDS on payment basis then they have to finalise the TDS in the month of february not in the month of march. But most of the companies deduct TDS on salary on due basis also as they finalize TDS on salary in the month of March. In above case if they will deduct TDS on payment basis(assuming TDS is finalized in the month of march) then the TDS return will be changed from 4th qtr to 1st qtr of the next A.Y. So if they are finalizing the TDS on March in such a case TDS should be dedcuted on provisonal basis on march 31 and should be deposited upto April7.
Correct me if im wrong
