- The residential status of an individual or entity determines whether income earned inside or outside India is taxable in India. - There are different residential statuses for individuals/HUFs and other entities like firms. For individuals, the statuses are resident and ordinarily resident, resident but not ordinarily resident, and non-resident. - Determining the residential status involves assessing whether basic or additional conditions are met based on the number of days spent in India in the relevant period. Meeting these conditions establishes whether one is a resident and ordinarily resident, or resident but not ordinarily resident.
