Which itr to file to claim tds on interest

The assessee can file the return of income by showing other source income on which TDS has been deducted in nature of interest by the bank. As the assessee does not have any other income it is very possible that there is income below taxable limit only so in order to claim refund the income under the head other source can be shown and refund amount can be claimed easily by filing form ITR 1.
For future purpose it is advisable to fill form 15G/H with the bank.

ok. Thanks Peeyush.
