How to Change GST Registration Details of a Business?

Running a business in India means you need to follow GST rules, including keeping your registration details up to date. If you’ve moved offices, changed your phone number, or updated your email, the GST authorities need to know about it.

The good news? You can update most of your GST registration details online through the GST portal without visiting any government offices. If you’re wondering how to change GST address, update contact information, or modify other registration details, you’re in the right place. 

This guide breaks down the entire process to help you update your GST details easily and correctly.

What Changes are Allowed in GST Registration?

Changes to GST registration can be made in two categories:

• Core Fields (require officer approval): Legal name of business, address of principal or additional place of business, and addition/removal of partners, directors, or authorised signatories.
• Non-Core Fields (auto-approved): Email, mobile number, bank account details, and other minor changes to details.

How to Change Address in the GST Portal?

Use this step-by-step guide to change GST address.

1. Log in to the GST Portal: Visit www.gst.gov.in and log in with your credentials.
2. Navigate to Amendment of Registration (Core Fields): Click on Services > Registration > Amendment of Registration Core Fields.
3. Edit Business Address: Click on the relevant tab: ‘Principal Place of Business’ or ‘Additional Places of Business’. Now, edit the address fields as required.
4. Upload Supporting Documents: You must upload your proof of address. 
5. Authorization and Submission: Select the authorized signatory and digitally sign the application using DSC(Digital Signature Certificate), E-Sign, or EVC(Electronic Verification Code).
6. Track Status: Once an Application Reference Number (ARN) is generated, you can check the status under Track Application Status in your dashboard.

Documents Required for Change of Address in GST

To update your address on the GST portal, submit documents based on the type of premises. All files must be in JPG or PDF format, each not exceeding 1 MB. Here’s the checklist of documents needed to change GST address:

• Own Premises: Submit a recent property tax receipt, municipal khata, or electricity bill. These documents serve as proof of ownership for the business location.
• Rented/Leased Premises: Provide the rent or lease agreement along with the landlord’s ownership proof. This confirms both the rental arrangement and the landlord’s legal ownership of the property.
• Shared/Consent Premises: A consent letter from the property owner is required, along with their ownership proof. This setup is common in informal or co-working spaces.
• SEZ Premises: Upload the SEZ approval certificate issued by the Government of India. This certifies that the premises are officially recognized as part of a Special Economic Zone.

How to Change Mobile Number and Email ID in GST Registration?

You can change mobile number in GST and the email ID linked to your GST registration, using these steps:

1. Log in to the GST Portal.
2. Click on Services > Registration > Amendment of Registration Non-Core Fields.
3. Update contact details under the Promoter/Partners or Authorized Signatory tab. Click ‘Edit’ next to the relevant person, and enter the new email ID or mobile number.
4. Enter the OTPs sent to your new contact details (and old ones, if prompted).
5. Submit the amendment using DSC, E-Sign, or EVC.

The change is effective immediately after successful submission, and both you and the GST department will be notified.

Time Required for Change in Address or Other Details

Updating GST registration details doesn’t always take the same amount of time. It depends on the type of change being made. Here’s what to expect:

• Core Field Amendments (e.g., business address or legal name): Takes up to 15 business days for approval by the GST officer. If additional documents or clarification are needed, a notice is sent via the GST portal or email.
• Non-Core Field Amendments (e.g., email or mobile number): These changes are auto-approved once verified using OTP, DSC, E-Sign, or EVC. You’ll get an acknowledgment within 15 minutes, and the update takes effect immediately.

How to Download Your Updated GST Registration Certificate

Once the core field amendment (like an address change) is approved, the updated address change in GST certificate becomes available for download. Here’s how to access it:

• Step 1: Log in to the GST Portal: Go to the Dashboard after logging in with your credentials.
• Step 2: Access Certificate Section: Click on View/Download Certificates to view your latest registration documents.
• Step 3: Download Updated Certificate: Download and save the changed GST registration certificate for your records.
