In today's digital age, having accurate and up-to-date contact information is necessary for efficient communication between businesses and government authorities. Your registered email ID is a key component in India's Goods and Services Tax (GST) system to receive important updates, notifications, OTPs, and other communications. Knowing how to change your email in the GST portal is important for all taxpayers, whether freelancers, partnerships, or corporations.
The GST portal serves as the primary interface for all the activities related to GST, including filing, generating invoices, and compliance. The registered email ID is the main channel of communication with the Goods and Services Tax Network (GSTN). Having a current and accessible email provides a reliable communication channel that supports compliance and avoids the risk of due dates being missed. A valid email ID linked with your GST account ensures you receive:
1: Notifications and updates related to return filing and other deadlines.
2: Alerts on mismatched input tax credits or returns being rejected.
3: One-time password (OTP) and authentication messages for login or profile changes.
4: Acknowledgement receipts and messages related to your GST registration.
If you do not have access to your registered email or it is inactive, it might lead to a failure to obtain access for confirmation or other complications.
The following people are permitted to initiate the email change to a new email ID:
1: The primary authorised signatory shown on the GST registration
2: Any other authorised signatories with administrative rights
3: In the case of businesses such as partnerships, LLPs, or companies, the person whose Digital
Signature Certificate (DSC) or e-Sign is registered on the portal may initiate the changes.
If you are not an authorised signatory, you will not be permitted to edit or update your contact person on the GST portal. So you want to make sure that the proper person has been assigned the role of authorised signatory before you attempt to update.
