GST Registration Amendments — Complete Guide

What is a GST Registration Amendment?

A GST Registration Amendment means updating or modifying details in your existing GST registration with the GST Department.
It is mandatory whenever there is a change in details such as:

  • Business name
  • Address of principal or additional place of business
  • Contact details
  • Partners/Directors/Karta
  • Business constitution (e.g., Proprietorship to Partnership)
  • Core and non-core fields under GST.

Failing to update these details may lead to penalties or cancellation of your GST registration.

Types of GST Amendments

1. Core Field Amendments

Require GST officer approval.
Includes:

  • Legal name of business (without PAN change)
  • Principal place of business (address change)
  • Addition, deletion, or modification of partners, directors, Karta, Managing Committee members, etc.

2. Non-Core Field Amendments

Do not require GST officer approval.
Includes:

  • Change in email ID or mobile number (OTP verification required)
  • Addition of bank account details

3. Change in PAN

  • Change in PAN is not allowed under amendment — a new GST registration must be obtained.

As per GST law, any change in registration details must be updated within 15 days of the event of change.
Example: If you change your business address on 1st June, the amendment must be filed by 16th June.
