Nre account--tax not deducted in bank account

Dear Barkha,

As an NRI, if your tax liability is less than the TDS deducted from your income,you can file an income tax return to claim a refund.

1. Non-Resident Rupee (NRE) and Non-Resident Ordinary Rupee (NRO) account are the two accounts which can be maintained by Non-resident. It can be either Savings or Current Account depending upon the preference of the assessee.  
2. The amount credited in NRE account is not taxable as it is nothing but a foreign income remitted in foreign currency. And interest earned on this account is not tax-deductible. 
3. NRO account is denominated in rupee for the income earned in India. Interest earned on this is subject to tax and TDS is deductible on the same. 
4. Being an Individual (Resident or Non-resident) whose income is below Rs. 2,50,000 during the year need not file IT return. Since TDS was deducted on the interest portion, for claiming the refund return shall be filed. But it is not mandatory to file IT return. 
Please correct me if the above solution has an alternative view.
