A Practical Guide to GST Amendment, Cancellation & Revocation
A GST registration is not a static certificate — it is a living record that must track every change in your business: a new director, a shifted office, an added product line, a bank account switch, or the day your business finally winds down. Get an amendment wrong and you operate with a GSTIN that no longer matches reality, inviting officer scrutiny. Get a cancellation wrong and you leave a dormant registration accumulating late fees for years.
What This Actually Covers
GST registration amendment, cancellation, and revocation are three distinct but related procedures under the CGST Act, 2017 and the CGST Rules, 2017, governing how a registered person changes, ends, or restores their GST registration. An amendment (Form GST REG-14) updates the particulars recorded against your GSTIN — legal name, trade name, principal place of business, additional places of business, details of partners or directors, or bank account information — without disturbing the GSTIN itself. Amendments are classified as either 'core field' changes (legal name of business, addition or deletion of a partner/director/promoter, principal place of business, or additional place of business) which require GST officer approval within 15 working days, or 'non-core field' changes (most other particulars, such as mobile number, email, or bank account details) which are auto-approved on submission and do not need officer sign-off.

Signs This Applies to You
- Your business has changed its legal name, trade name, principal place of business, or added/removed a place of business — a core-field amendment via REG-14 is required within 15 days of the change
- A partner, director, Karta, or authorised signatory has changed — mandatory core-field amendment, with the outgoing signatory's authorisation replaced before any further filings are made under their name
- Your bank account details, mobile number, or email address associated with the GSTIN has changed — a straightforward non-core amendment, auto-approved on submission
- Your business has genuinely ceased operations, been sold, merged, or converted into a different legal structure requiring a new PAN — voluntary cancellation via REG-16 is the correct closing step
Before You Assume You Need This
- Your business is only temporarily slow or seasonal, with every intention to resume full operations — cancelling the registration in this scenario means a fresh REG-01 application, a new GSTIN, and loss of continuity when you resume; consider filing nil returns instead
- You want to change the composition-vs-regular scheme election — this is handled through Form CMP-02 (opting into composition) or CMP-04 (opting out), not through the REG-14 amendment or REG-16 cancellation process
- Your registration was cancelled voluntarily by you (not by the officer) and you have changed your mind — revocation under Section 30 applies only to officer-initiated cancellations under Section 29(2); a voluntarily-cancelled GSTIN cannot be revived through REG-21, and a completely fresh registration is the only path back
Quick Answers
What is the difference between a core field and a non-core field in a GST amendment?
Core fields are particulars whose change requires GST officer approval before taking effect: the legal name of the business (without change in PAN), the principal place of business (other than a change in state), the addition, deletion, or retirement of partners/directors/Karta/managing committee members who are authorised signatories, and the addition of an additional place of business. Non-core fields cover most other details — mobile number, email address, bank account information, and similar particulars — which are auto-approved on submission via Form GST REG-14 without officer intervention.
How long does the GST officer have to act on an amendment application?
For core-field amendments, the proper officer has 15 working days from the date of application to approve the amendment, or to issue a notice seeking additional information or documents, in Form GST REG-03. If the officer does not act within 15 working days, the amendment is deemed approved. Non-core field amendments are approved automatically on submission and do not go through officer review.
Can I amend my GSTIN itself — for example, to reflect a new PAN after converting my proprietorship to a private limited company?
No. The GSTIN is derived from the PAN, and a change of PAN cannot be handled through an amendment. Where the constitution of the business changes in a way that requires a new PAN (proprietorship converting to a company, for instance), the correct process is to cancel the old registration (after the final return) and apply for a fresh GST registration under the new PAN and entity structure. Unutilised input tax credit in the old entity's electronic credit ledger can be transferred to the new entity via Form GST ITC-02, subject to conditions.
