If I were to invest my US salary in India say in Fixed Deposits and pay tax on the interest earned in india, will I get benefit of double taxation treaty between US and India or would I need to pay tax again in the US. How do I show it in my tax return. What would happen if interest income is my only source of income in india as a result of which I fall below the basic exemption limit and therefore don't have to pay tax in India.
