The document discusses the scope of total income based on a taxpayer's residential status in India as a resident and ordinarily resident, resident but not ordinarily resident, or non-resident. It outlines the different types of income that are taxable or not taxable in India for each residential status, based on factors such as where the income was earned and received, and whether it relates to a business or profession in or outside of India. The three main considerations for determining the scope of total income and tax incidence are the taxpayer's residential status, place of accrual or receipt of income, and the time at which income had accrued or was received.
