Hello,
I am on H1 visa in USA. I have a NRE account in India in which I transfer money into. The money gets converted into INR after it has been credited to my account in India. I do not receive any kind on documentation (1099-INT or likewise) showing the interest earned on that interest bearing account. Income tax is exempt on interest earned in NRE accounts.
1.) Do I need to declare the account's amount on form TD F 90.22-1 if it is more than $10K at any time during the year.
2.) Do I need to declare the interest earned on that account?

If I do declare it and I pay to extra taxes, doesn't it mean I am paying taxes on amounts that I am already declaring as part of my earnings and have already paid taxes on.

Apologies, if I am confusing the questions or wording it wrong. I am not well versed with tax terminologies. Thanks in advance for helping me.

If you are a U.S. resident then you must report the foreign account and include all of your worldwide income on your U.S. tax return.

Thanks for the reply.
I have another question. My foreign bank did not send me 1099INT. How do I report the interest in that case? Should I just write the interest earned in schedule B by converting the interest earned in INR into USD?

Yes, you will report interest income. Even the interest earned on your NRE account. Convert INR to USD.
You may also need to file TD F 90.22-1. Your U.S. Tax Return: U.S. Citizen or Resident with Foreign Income (http://taxipay.blogspot.com/2008/03/us-citizen-or-resident-with-foreign.html)
