What Is Amendment of GST Registration?
Amendment of GST registration is the formal process of updating the details recorded against your GSTIN after your original registration was approved. It's governed by Rule 19 of the CGST Rules, and it's how you notify the department about changes to your business name, address, promoters, authorised signatory, contact details, or additional places of business.
The law doesn't treat this as optional housekeeping. Section 28 of the CGST Act requires a registered person to inform the proper officer of any change in the particulars furnished at registration within 15 days of that change occurring. Missing that window is where most compliance problems begin.
Core vs Non-Core Fields: The Distinction That Decides Everything
Before filing anything, you need to know which category your change falls into, because it determines the form used, whether an officer reviews it, and how long approval takes.
| Aspect | Core Fields | Non-Core Fields |
|---|---|---|
| What it covers | Legal/trade name, principal place of business, additional places of business, addition or removal of partners, directors, karta, or managing committee members | Bank account details, email address, mobile number, most other particulars not listed as core |
| Officer approval | Required — reviewed by the proper officer | Not required — auto-approved on the portal |
| Typical timeline | Approval generally within 15 working days of application | Reflected almost immediately after submission |
| Form used | Form GST REG-14, with approval issued in Form GST REG-15 | Form GST REG-14, processed without officer intervention |
One important limitation: a change in PAN is not an amendment. Since the GSTIN is built on the PAN, any change that alters the PAN, such as converting a proprietorship into a private limited company, requires cancelling the existing registration and applying for a fresh one.
When Must You Amend Your GST Registration?
Change of Business Address
Shifting your principal place of business, or relocating within the same state, requires a core field amendment with fresh address proof.
Adding a Branch or Warehouse
Opening a new office, godown, or additional place of business within the same state must be added to your registration.
Change in Trade or Legal Name
Rebranding or a formal legal name change needs updating, supported by the relevant incorporation or registration document.
Change of Authorised Signatory
When the person authorised to file and sign GST documents changes, the registration must reflect the new signatory.
Addition or Exit of Partners/Directors
Any change in partners, directors, karta, or managing committee members is a core field amendment.
Updated Bank or Contact Details
New bank account, email, or mobile number are non-core amendments that update without officer approval.
Documents Required for GST Amendment
The documents you need depend on what you're changing. Here's what applies to the most common amendments.
For a Name Change
- Certificate of Incorporation (companies)
- Partnership deed (partnership firms)
- Certificate of registration (proprietorships)
- Updated PAN card reflecting the new name, where applicable
For an Address Change
- Electricity, water, or telephone bill not older than two months
- Rent or lease agreement, if the premises are rented
- Sale deed or property tax receipt, if owned
- Landlord's No Objection Certificate, where required
For a Change of Authorised Signatory
- PAN and Aadhaar of the new signatory
- Photograph of the new signatory
- Board resolution (companies) or partnership resolution authorising the appointment
For Bank or Activity Changes
- Cancelled cheque or bank statement showing name, account number, and IFSC
- MoA and AoA, or partnership deed, for changes in business activity
- Trade licence or supporting document for newly added activities

How to File a GST Registration Amendment: Step by Step
Identify Whether Your Change Is Core or Non-Core
We first confirm which category your amendment falls into, since this determines whether officer approval is needed and how long it takes.
Share Your Details and Documents
Send us your GSTIN, the details being changed, and supporting documents over WhatsApp or email, then complete payment to begin.
Log In and Open the Amendment Application
On the GST portal, the amendment is opened under Services, then Registration, then Amendment of Registration, selecting core or non-core fields as applicable.
Update the Fields and Attach Proof
The changed particulars are entered in Form gst reG-14 along with the supporting documents and the date on which the change took effect.
Verify and Submit with DSC or EVC
The application is submitted using a Digital Signature Certificate or Electronic Verification Code, and an ARN is generated for tracking.
Receive Approval and the Updated Certificate
Non-core changes reflect almost immediately; core changes are approved in Form GST REG-15, after which the amended certificate can be downloaded.
What If the Officer Raises a Query or Rejects the Amendment?
For core field amendments, the proper officer can issue a show cause notice in Form GST REG-03 if the application appears incomplete or unsatisfactory. You then have seven working days to respond in Form GST REG-04 with clarification or additional documents. If the response is accepted, the amendment is approved; if not, rejection is issued in Form GST REG-05.
A practical point worth knowing: if the officer takes no action within the prescribed period, the amendment is generally treated as deemed approved. Our team monitors your ARN and responds to any query on your behalf, which is where most self-filed amendments run into delays.
What Happens If You Don't Amend Your GST Registration?
Penalty Exposure
Failure to inform the department of a change within 15 days can attract a general penalty under Section 125 of the CGST Act.
Input Tax Credit Disputes
Invoices issued from an address not recorded on your GSTIN can create ITC problems for you and your customers.
E-Way Bill Mismatches
Dispatching goods from an unregistered additional place of business can cause e-way bill and transit verification issues.
Departmental Notices
Discrepancies between your actual operations and your GST records commonly trigger notices and follow-up scrutiny.
Failed Communication
An outdated email or mobile number means you may never receive critical notices, leaving deadlines to lapse silently.
Audit Complications
Inconsistent registration details are a routine trigger for deeper scrutiny during a GST audit.
