A Resident in India: -- World Income is taxable in India.

But.............the DTAA provisions safeguard him......i.e. 

there are 2 ways in which DTAA saves you.

1) You will get a credit of the tax paid in US....in the absence of any DTAA agreement between usa and India ( But there exists a DTAA Agreement between India & USA ).

2) So if we have DTAA Agreement with USA  you will be taxed at the rate specified in DTAA or Indian Income Tax whichever is beneficial to the assessee.
