Do we need to pay seperate income tax even if we fill Form 15G and 15H ?

Hi,

For investment in FD, usually bank asks to fill 15g/15h forms. As per my understanding these are used to not deduct any tax from bank (Tax deducted at Source) but if we are in 20%/30% tax bracket then we need to submit separate tax for these FD investment. Considering FD interest in one branch goes beyod 10k

Please correct here

Thanks in advance
