I am on a 6 month assignment to work in my parent company in USA from India(where I am permanantly employed).

For my tenure of stay, I have been told that all remittances to my local bank account in $ are Tax Equalized - meaning I will not be liable to pay any more or any less tax than what I am currently paying in my home country. Beyond this information, I do not have any system of record like Pay slip or et al.

I would like to know what will be my tax liablility if I were to send some dollar remittance to India - will I be liable to tax there too - if yes what %? And what documentary proof would I need, to avoid double taxation?

If you are in the U.S. for less than 183 days, then your income is tax exempt.

This opinion on the fact that the income is being paid from India, not froma U.S.-based subsidiary.
