What it is
What is GST registration amendment?
In short: a GST registration amendment updates the details you gave when you registered. You file Form GST REG-14 on the GST portal within 15 days of the change. Some changes need a tax officer's approval (core fields). The rest are approved as soon as you file (non-core fields).
When
When do you need a GST amendment?
- You moved your office or added a branch or godown: principal or additional place of business. Core: needs approval.
- You renamed the business: legal name (same PAN). Core: needs approval.
- A partner or director joined or left: core: needs approval.
- You changed the authorised signatory, mobile number, email or bank account: non-core: updates on filing.

How it works
GST amendment process
01
Tell us what changed
We confirm whether it is a core or non-core change and send you the document list.
02
We prepare Form REG-14
We fill in the right tab, the date of amendment and the reason, and upload the proof.
03
You sign
With a DSC, e-sign or the OTP sent to your phone. The portal gives an ARN.
04
We follow it to the end
Non-core changes are done on filing. For core changes we track the ARN until the officer issues Form REG-15, and we send you the new certificate.
Timeline

File the amendment
Within 15 days of the change
Non-core change
Approved on filing
Core change: officer approves (REG-15) or asks a question (REG-03)
Within 15 working days of filing
Your reply to a query (REG-04)
Within 7 working days of the notice
Officer does nothing
Approved automatically after 15 working days (or 7 working days after your reply)
Proposed: on 8 October 2026 the GST Council recommended that amendments, except a change of principal place of business, be accepted automatically. As of 11 October 2026 this is not in force. Read more in our GST amendment guide.
Pricing
GST amendment fees
- We quote the fee in writing before we begin.
Approval
What can slow down approval
The officer can ask for more information in Form REG-03, and can reject in Form REG-05 if the reply does not satisfy or does not come. To avoid a query:
- The proof must match the change. The address on the rent agreement or bill must match the address you enter.
- Reply in time. You have 7 working days to reply to a REG-03 notice.
- Check the State. A move to another State cannot be done by amendment.

FAQs
GST amendment, answered
What is the difference between core and non-core changes?
Core changes (legal name, business addresses, partners and directors) need a tax officer's approval. Non-core changes (authorised signatory, mobile, email, bank account and other details) are approved as soon as they are filed.
Is a change of authorised signatory a core change?
No. The authorised signatory is a non-core field, so the change is approved on filing. A change of partners or directors is a core change.
How long does a GST amendment take?
A non-core change is approved on filing. For a core change, the officer has 15 working days to approve it or raise a query. If the officer does nothing, the change is approved automatically.
What is the time limit to apply?
Within 15 days of the change.
Which form is used for a GST amendment?
Form GST REG-14. The approval order is Form GST REG-15.
Can you change my GST address to another State?
No. GST registration is State by State. Moving the principal place to another State needs a fresh registration there, and the old one is cancelled.
My PAN has changed. Can you amend my GSTIN?
No. A PAN change, for example a proprietorship becoming a company, needs a fresh GST registration in Form REG-01.
Will I get a new GST certificate?
For a core change, yes: a new certificate is issued after approval. Non-core changes do not appear on the certificate.
Is the 15-day limit strict?
The rule says 15 days. File as soon as the change happens.
