How to Amend Your GST Registration Using Form GST REG-14

How do I amend my GST registration details?

File Form GST REG-14 on the GST portal under Services > Registration > Amendment of Registration. Select core or non-core field amendment depending on the type of change. Non-core changes (trade name, contact details, bank account) are auto-approved. Core changes (legal name, principal place of business, partners/directors) need officer approval within 15 working days. (Source: Rule 19, CGST Rules 2017; tutorial.gst.gov.in)

Frequently Asked Questions

What is Form GST REG-14?

Form GST REG-14 is the application for amendment of GST registration. It is filed online on the GST portal to update any details in your GST registration certificate. The form covers both core field amendments (which need tax officer approval) and non-core field amendments (which are auto-approved).

What are core fields and non-core fields in GST registration?

Core fields are legal name of business, principal place of business, additional places of business, and details of partners, directors, or designated partners. Changes to these need officer approval. Non-core fields include trade name, mobile number, email address, authorized signatory, and bank account details. These changes are auto-approved on submission.

How long does GST registration amendment approval take?

Non-core amendments are auto-approved immediately on submission. Core amendments must be approved by the jurisdictional tax officer within 15 working days. If the officer does not act within this period, the amendment is deemed approved and the registration certificate is updated automatically.

Can I change my GST registration from one state to another?

No. GST registration is state-specific. If your principal place of business moves to a different state, you must apply for cancellation of the existing registration and take a new registration in the new state. An amendment under REG-14 cannot change the state.

What happens if I do not amend my registration within 15 days?

Rule 19 of the CGST Rules requires filing the amendment within 15 days of the change. Failure to do so may attract a notice from the tax officer and, in practice, may cause issues with e-way bill generation, GSTR-1 filing (if address-linked HSN codes change), and ITC eligibility for the recipient.

Business details change. You shift your office, add a partner, open a new branch, update your bank account, or change the authorized person who signs your returns. When any of these happen, your GST registration certificate must reflect the current facts. The mechanism is Form GST REG-14.

This guide covers what you can and cannot change, the difference between core and non-core amendments, the step-by-step process on the portal, and the documents you need. For the initial registration process, see our GST registration guide. For tracking your application status, see the ARN status check guide.

Core Fields vs Non-Core Fields

The GST portal classifies all registration fields into two categories. The category determines whether the change takes effect immediately or requires officer approval.

Core Fields (Officer Approval Required)

Core field changes require the jurisdictional GST officer to verify documents and approve the application. The officer has 15 working days to approve or reject. If no action is taken, the amendment is deemed approved and the certificate updates automatically.

Non-Core Fields (Auto-Approved)

Non-core amendments take effect the moment you submit the form. No officer approval is needed. The updated registration certificate in Form GST REG-06 is available for download immediately.

When You Cannot Use Amendment

Form GST REG-14 has limits. You need a fresh registration in these situations:

1. Change of PAN: PAN is the foundation of GSTIN. A PAN change (due to conversion from proprietorship to company, for instance) requires a new registration. See our proprietorship to private limited conversion guide.

2. Change of state: Moving your principal place of business from Maharashtra to Karnataka means you need to cancel the Maharashtra registration and apply fresh in Karnataka. GSTIN is state-specific.

3. Change of constitution of business: Converting from proprietorship to partnership, or from partnership to LLP, changes the legal entity and typically the PAN. This requires a new registration.

Officer Approval Process for Core Amendments

When you submit a core field amendment, the process follows this sequence:

2. Officer review: The jurisdictional officer (usually the superintendent or assistant commissioner assigned to your GSTIN) reviews the application and uploaded documents.

3. Approval or clarification:

   • If satisfied, the officer approves the amendment. The updated certificate in Form GST REG-06 is issued and available for download.
   • If not satisfied, the officer issues a notice in Form GST REG-03 requesting additional documents or clarification. You must respond in Form GST REG-04 within 7 working days. For responding to REG-03 notices, see our GST REG-03 notice reply guide.

4. Rejection: If the officer rejects the amendment, the rejection order is issued in Form GST REG-05 with reasons. You can file a fresh amendment application addressing the deficiencies.

5. Deemed approval: If the officer takes no action within 15 working days (excluding any clarification period), the amendment is deemed approved. The registration certificate updates automatically.

Important Restrictions and Practical Tips

You Cannot File Non-Core While Core Is Pending

If you have a pending core amendment application (ARN generated, awaiting officer action), the portal blocks non-core amendment filing until the core application is approved or rejected. Plan accordingly: file non-core changes first, then core changes, or wait for core approval before filing non-core updates.

Multiple Changes in One Application

You can change multiple fields in a single REG-14 application. If you are changing both your address (core) and your mobile number (non-core), file them separately: the mobile number as a non-core amendment (instant), and the address as a core amendment (needs approval). Mixing them in one application is not supported because the portal routes core and non-core amendments through different workflows.

Amendment Effective Date

For core amendments, the effective date is the date of approval (or deemed approval), not the date of filing. For non-core amendments, the effective date is the date of submission. Plan your invoicing and returns accordingly: invoices issued between the date of change and the date of approval should reflect the old details until the certificate is updated.

Impact on GSTR-1 and E-Way Bills

If your principal place of business address changes, your e-way bill generation, GSTR-1 place of supply defaults, and state-level auto-population may be affected. After the amendment is approved, verify that your e-way bill profile reflects the updated address. If you generate e-way bills from third-party software (Tally, Busy, Zoho), update the address in your software as well.

Annual Return Cross-Check

GSTR-9 (annual return) pulls data from your registration details. If you amended registration during the year, verify that Part V of GSTR-9 reflects the correct details. For annual return filing guidance, see our GSTR-9 filing guide.
