Basic exemption limit how does the bank calculates from apparent records.For example I hv 3 lacs as opening balance during the financial year ,during the year there are certain transactions which are max to 2 lacs. so how does bank deduct deduction tds. The basic exemption limit is 2.5 lacs after that what happens?It's taxable. Now after the bank deducts considering exemption of Sec 80TTA/80TTB. BANK IS UNDER OBLIGATION TO GIVE TDS CERTIFICATE. SO WHO IS RESPONSIBLE?
