Income tax for Non-Resident Indians (NRIs) refers to the taxation policies applicable to individuals of Indian origin who reside outside India. NRIs are taxed only on income earned or accrued in India, such as rental income, capital gains from property sales, and interest from Indian bank accounts. They are exempt from tax on foreign income. NRIs must file tax returns in India if their income exceeds the basic exemption limit. Understanding the provisions of the Double Taxation Avoidance Agreement (DTAA) between India and their country of residence is crucial for NRIs to avoid double taxation.
