An individual's residential status determines their tax liability in India. There are three residential statuses: resident and ordinary resident, resident but not ordinary resident, and non-resident. An individual's residential status depends on the number of days they spent in India in the last year and last few years. Additionally, an individual must meet further criteria to be considered an ordinary resident. The residential status principles are also applied to HUFs, firms, companies, and other entities to determine their tax obligations. An individual or entity's residential status then dictates whether their global income is subject to tax in India.
