Under Section 6(1) of the Income Tax Act, an individual’s residential status is determined based on their stay in India during a financial year. An individual is classified as a resident if they stay in India for 182 days or more during the year, or if they stay for 60 days or more in a year and have been in India for a total of 365 days or more in the preceding four years. The residential status of a taxpayer is significant as it determines their tax liability, as residents are taxed on their global income, while non-residents are only taxed on income earned in India. Understanding this status is crucial for compliance with the Income Tax Act and to ensure accurate tax filing.
