Can a resident Zerodha account be used even after going abroad?

A resident Zerodha account can be used even after going abroad if the stay is less than 6 months. If it is more, a resident would be considered NRI, and the resident account would have to be converted to an NRO account, see Can an existing Zerodha account be converted to an NRI account? Or the resident account can be closed, and a new NRI account can be opened. See How to close the Zerodha account? and What documents are required to open a Zerodha account as an NRI?

Did you know? When a person moves abroad for employment, business, or any other purpose, that indicates their intention to stay outside India for an uncertain period. In that case, they become a non-resident from the day they leave India.
