The Income Tax Act defines who is Resident or Non-Resident (NRI).
Published
π An individual is considered a Resident in India if:
He stays in India for 182 days or more during the relevant financial year, OR
He stays in India for 60 days or more during that financial year and for 365 days or more in the last 4 years.
So, the rule is:
If you stay in India 182 days or more, you are Resident.
If you stay in India less than 182 days, you are treated as NRI.
