Akgarg thanks for the info. I have two more questions:
1. Do they send something similar to 1099 (for NRE/NRO Accounts) for filing US tax returns?
---------------only Citibank sends as the bank is not indian bank. ICICI, HDFC, AXIS dont send and for NRE A/C Intrest no tax is paid in India
2. Should we pay Indian Tax for the interest on those accounts?
------------------not on NRE A/C but on NRO (non Resident Ordinary) bank can deduct 30% intrest . you can write email to ICICI, HDFC and can find out the full details
Thanks,
