How to Change Email ID on GST Portal: Complete Guide

Why Your Email ID on the GST Portal Matters

Your email ID linked to the GST portal is the primary communication channel between you and the Goods and Services Tax Network (GSTN). All important notifications—including return filing reminders, order copies, notices, and OTP verifications—are sent to this registered email address. An outdated or incorrect email can cause you to miss critical compliance deadlines and government communications.

Whether you've changed your business email, experienced a security breach, or simply want to consolidate communications, updating your email on the GST portal is essential for smooth GST compliance.

Who Is Eligible to Change the Email ID?

Not everyone associated with a GSTIN can initiate an email change. The following persons are eligible:

• Primary Authorised Signatory: The main person authorised to operate the GST account.
• Proprietor / Partner / Director: Key managerial personnel of the registered business.
• Authorised Representative: A CA, CS, or tax professional appointed via the portal.

It is important to note that only the primary authorised signatory can directly amend the email ID through the non-core amendment process on the GST portal.

Types of Amendments on the GST Portal

The GST portal categorises changes into two types:

Changing the email ID falls under non-core amendments, meaning the change takes effect immediately after successful OTP verification without requiring approval from a tax officer.

Step-by-Step Process to Change Email ID on GST Portal

Step 1: Log In to the GST Portal

Visit www.gst.gov.in and log in using your valid credentials (username and password). Navigate to Services > Registration > Amendment of Registration Non-Core Fields.

Step 2: Navigate to the Authorised Signatory Tab

Once the amendment form opens, click on the "Authorised Signatory" tab. Here you will see the currently registered email ID and mobile number associated with the primary authorised signatory.

Step 3: Edit the Email ID

Click the edit icon next to the email address field. Enter your new email ID carefully, ensuring there are no typos. The system will prompt you to verify the new email via OTP.

Step 4: OTP Verification

An OTP will be sent to both your new email ID and the registered mobile number. Enter both OTPs in the respective fields within the validity window (usually 10 minutes). If the OTP expires, you can request a new one.

Step 5: Submit and Confirm

After successful OTP verification, the amendment form will be submitted. You will receive a confirmation message on the portal, and an acknowledgement will be sent to your new email ID.

Common Issues and Troubleshooting

• OTP not received: Check your spam/junk folder. Ensure the new email ID is valid and accessible. Wait a few minutes and retry.
• Mobile number also outdated: If your registered mobile number is also outdated, you may need to update it simultaneously or approach a GST Suvidha Kendra for assistance.
• Portal errors: Clear browser cache, use Google Chrome, and try during off-peak hours (early morning or late evening).
• Multiple GSTINs: If you have multiple GSTINs, the email change must be done separately for each registration.

Security Measures to Protect Your GST Account

Since your email is a gateway to your GST account, follow these security best practices:

• Use a dedicated business email for GST communications rather than a personal one.
• Enable two-factor authentication on your email account.
• Never share your GST login credentials or OTPs with unauthorised persons.
• Regularly review your authorised signatory details to ensure they are up to date.
• Change your GST portal password periodically and use a strong, unique password.
