NRI return

If the income is earned or accrued in India, it will be taxable in India; but the source of income should be authentic.

1. As you have mentioned any income for which tax has already been paid outside India will be governed by DTAA provision. 
2. Your salary income will not be taxable in India as you clearly mentioned you are an NRI during the year. 
3. But with respect to other income, it will be taxable in India if the same is accrued or arise or deemed to accrue or arise in India as per sec 9 of the act.
4. Such income directly or indirectly arises out of "business connection in India or through or from any property in India or through or from any asset or source of income in India, or through the transfer of a capital asset situate in India". 
5. If the money that you are referring to is from any source as I mentioned above then it will be taxable in India. 
Please correct me if the above solution has an alternative view.
