Tax Liability on Mutual Fund Reedeemed

Dear Experts ,

Previously I had try  to Know that what will be my Tax liability on income earned on reedeemtion of Mutual  Fund in which I have stayed invested for more than 3 yrs. I was replied that if STT is paid on reedemtion than there will not be any Tax Liability. On checking the reedeemption  certificate i found that STT was paid in all cases. So kindly help me by informing under which section I should claim the exemption on the money earned.(Reedemption price of unit - Cost of Unit in NFO == Profit Earned)

Regards,
