Is itr filing required for fd interest earning only ?

ITR is not required for income purposes. But as the TDS will be deducted on such FD interest, you need to file ITR to claim such deducted tax as refund.

@ RAM J.

If you have only FD interest and no other taxable income and that FD interest is below the basic exemption limit then you are not required to file your return. I.e to say your gross total income should not exceed the basic exemption limit.

In the present case you are required to file your return, Deductions u/c VI A are not to be considered for determining mandatory filing of return

@ CA SURI KOTA:

I dont agree. Apart to claiming refund, it is mandatory to file return if GTI exceeds basic exemption limit. Refer Sec139(1) 

Agree wth Rinkal. 

Its not just about refunds, you have to file the return in this case even if you dont have any refund. How is government supposed to know if you have done tax saving investments! In salaried cases below 5 Lac where you have a form 16 that encompases all incomes and VIA deductions and all taxes are paid then it can be exempted as form 16 can be treated a return as these details are there in TRACES. Still in this salary case also if you have refund you have to file return.

the FD interest will treat as income from other source.,

we have to consider that point also
