Bank has deducted instalment of Income Tax from Pension. After deduction of investment under section 80C tax liability is nil. Bank couldn't be informed about this earlier, but informed about this soon after deduction of first installment by Bank. Even after informing Bank about the investment, the Bank again deducted second installment of Tax. Please let me know the rule position about this. Is Bank not authorized to take into consideration of investment under sec 80C while deducing tax?
