Taxation of overseas salary

U will be considered as Indian resident since the stay was less than 182days in an year. This would imply that u would need to pay tax in India as per ur income slab. India and US does have double taxation treaty and so they will be applicable as well.

The tax treaty will lower your taxes in US. US will give you credit for Indian taxes paid. It is hard to find experts in Tax Treaty so good luck to you. Your tax bite will be hefty. In future try to have assignment exceeding 182 days. Then you would have been non resident in India and your global income will not be taxed in India. US does not tax global income of non residents.
