How to Amend Your GST Registration Details: Core vs. Non-Core Fields Explained in Sholinganallur

Businesses evolve — addresses change, partners join or leave, and bank accounts get updated. GST registration allows for amendments to reflect these changes, but the process differs depending on which type of field you're updating.

Core fields vs. non-core fields

The GST portal categorizes amendable information into two types:

Core fields — changes here require approval from a GST officer:

• Legal name of the business (without change in PAN)
• Principal place of business (address changes, not state changes)
• Addition or deletion of additional places of business
• Addition, deletion, or change in details of partners/promoters/directors

Non-core fields — changes here are auto-approved and reflected immediately:

• Bank account details
• Authorized signatory details (in some cases)
• Details related to goods and services offered
• Contact details like email and mobile number (may require OTP verification)

Steps to file an amendment

1. Log in to the GST portal and go to "Services" > "Registration" > "Amendment of Registration Non-Core Fields" or "Core Fields" depending on your change.
2. Edit the relevant section and upload supporting documents (e.g., new address proof for a business relocation).
3. Submit using DSC or EVC (Aadhaar OTP).
4. For core field amendments, a GST officer reviews the request and either approves or seeks clarification within 15 working days.

What you cannot amend

Some details, like PAN or the state of registration, cannot be amended — because GST registration is fundamentally tied to your PAN and state. If your business changes its PAN (e.g., due to a change in legal constitution) or relocates to a different state, you must apply for a fresh GST registration and cancel the old one, rather than filing an amendment.

Timeline for filing amendments

Any change in registration particulars must be reported within 15 days of the event occurring — for example, within 15 days of a new partner joining or an address change.

Keeping your GST registration details current isn't just administrative housekeeping — inaccurate details can complicate return filing, e-way bill generation, and even bank loan applications that require GST verification.
