• Income tax for American citizen with OCI and residence in India

Hello, 

I am an American citizen and plan to marry an Indian citizen. I would be predominately living in India but earning income in the US through work from home, so I would need to pay taxes in the United States. However, I would like to eventually get an OCI card to make living in India with my future spouse easier. 

My questions are: 

1) If I am an American citizen with an OCI card living in India for roughly 10 months of the year, will I have to pay income tax in India? 

2) If answer to 1 is yes, will I need to pay on my global earnings (i.e. money earned through virtual work with a US-based company and any Indian earnings) or just on Indian earnings? 

3) If I have to file income taxes in India on all of my global earnings, would I be eligible for any program for double tax relief in order to decrease the tax burden in India?
