Non-Resident Indians (NRIs), Persons of Indian Origin (PIOs), and Overseas Citizens of India (OCIs) usually have the problem of being taxed twice on the same income—first in India and then again in the country where they are residing. To prevent such double taxation and lessen the burden of tax, India has entered into Double Taxation Avoidance Agreements (DTAAs) with over 90 nations, including the US, UK, UAE, Canada, and Australia.
