I want to pay quarterly interest Rs.15000 for a person. I have Paid first quarter interest Rs.15000 without deduction of tds on15.04.2016. TDS not deducted because i am received form 15G from that person. I have received form 15G on that date also... after that 15.07.2016 i paid second quarter interest Rs.15000 (tds not deducted because form 15G received early). Now my question is I want to file form 15G in online for every quarter or first quarter only ? Because i am received form 15G in first quarter itself for whole year.
