Dear Mr. Raghu,
Taxability of Income depends on the residential status of a person. As per Income Tax Act, the status of a person as a resident or non-resident depends on his period of stay in India.
Further the taxability based on Residential Status is described as below:
1. A person who is a non-resident (NRI):
i. Income earned from any source in India e.g. interest from investments in India, capital gains from investments and immovable property in India etc. is taxable in India.
ii. Any other Income earned or received in India is taxable in India.
iii. Income other than the above is not taxable in India.
2. A person who is resident but not-ordinarily resident (RNOR):
i. Income earned from any source in India e.g. interest from investments in India, capital gains from investments and immovable property in India etc. is taxable is India.
ii. Income earned outside India from Business controlled or profession set-up in India is taxable in India.
iii. Any other Income earned or received in India is taxable in India.
iv. Income other than above is not taxable
3. A person, who is Resident and ordinarily Resident (ROR) in India, is liable to pay tax in India on his world income.

Also, there are no seperate set of forms/process/submission etc. for filing ROI by NRI.
