01 / The basics
What counts as an amendment
Your GST registration records a set of particulars: your legal name, your principal and additional places of business, your bank accounts, your authorised signatories, and the partners or directors. When any of these change, the record has to change too. That update is an amendment, and it is filed in Form REG-14 under Rule 19 of the CGST Rules.
An amendment keeps your GSTIN. You do not get a new number when your address moves within the same State or when you add a bank account. A change of State, or a change that makes the registration invalid, is different and usually needs a new registration.
| Change | Usually | Notes |
|---|---|---|
| Trade name | Non-core | File REG-14. Update invoices once the change is shown on the portal. |
| Bank account | Non-core | Add the new account with a statement or cancelled cheque. |
| Contact email or mobile | Non-core | Use the registered contacts for OTP and notices, so keep them current. |
| Additional place of business | Non-core | Add it with proof of occupancy, such as a rent agreement. |
| Authorised signatory | Non-core | The added person must complete the authentication steps. |
| Partners or directors | Core | Officer approval is needed. Attach the board resolution or partnership deed. |
| Principal place of business | Core | A change within the same State is an amendment. A change of State needs new registration. |
| Legal name or constitution | Core | Match the PAN and incorporation records before you file. |
02 / Core vs non-core
Which fields are core, and why it matters
The portal groups registration fields into core and non-core. The difference matters because of what happens after you file. A non-core change is recorded and takes effect with limited checks. A core change alters the legal identity of the registration, so the proper officer must review and approve it before it becomes effective.
Core fields
Legal name, constitution of the business, principal place of business, and partners or directors. The officer approves the change, and may raise a query before doing so.
Check the portal label before filing.
The field list in the portal is what counts. If you are unsure whether a change is core, file it as the portal directs and follow any officer query, rather than guessing and missing the deadline.
03 / Filing REG-14
How to file an amendment on the GST portal
Gather the proof first. The form is quick, but the officer will check the documents against the change you describe.
- 01
Log in as the primary authorised signatory
Go to Services → Registration → Amendment of Registration Non-Core Fields or Core Fields, as applicable.
- 02
Select the fields that change
Tick only the particulars that are changing, and enter the new details exactly as they appear on your supporting documents.
- 03
Upload the supporting documents
Attach a clear scan of each document. Name the files so the officer can match each to the change.
- 04
Verify and sign
Confirm the declaration, then sign with a DSC or EVC. Save the Application Reference Number.
- 05
Track the status
Use Track Application Status with your ARN. Non-core changes usually show quickly. Core changes may take longer, and queries appear under notices.
- 06
Update your records
Once approved, update invoices, e-way bill templates, accounting software and any contracts that quote the old details.
04 / Documents
What to keep ready for each type of change
| Change | Document to attach |
|---|---|
| Address | Rent agreement or ownership proof, and a recent utility bill for the premises. |
| Bank account | Bank statement or cancelled cheque showing the account in the business name. |
| Partners or directors | Board resolution, partnership deed or revised incorporation documents. |
| Legal name | Certificate of incorporation or updated PAN record showing the new name. |
| Authorised signatory | Appointment letter, identity proof and contact details of the person. |
Keep every filed document with its ARN, so you can produce them quickly in a scrutiny or audit.
05 / Avoid these
Common mistakes that delay an amendment
- Filing a core change as non-core, then having to correct it after an officer query.
- Entering a name or address that does not match the supporting document, down to abbreviations and punctuation.
- Forgetting to remove a former authorised signatory, who can still sign returns.
- Updating the portal but not the invoices, e-way bill settings or accounting software, which then show the old details.
- Treating a State change as an amendment. It needs a new registration in the new State.
Tip:
Make one amendment per change, filed promptly, rather than bundling several unrelated changes into one application. Each then tracks on its own.
Questions people ask
Frequently asked questions
What is a GST amendment?
An amendment is a change to the particulars already on your GST registration, such as your trade name, address, bank account, contact details, authorised signatory or partners and directors. You make it in Form REG-14 on the GST portal, and your GSTIN stays the same. The rules for this sit in Rule 19 of the CGST Rules, 2017.
Which changes need REG-14?
Any change to the details shown on your registration certificate, or to the information in your application. That includes name, address, constitution of the business, bank accounts, promoters or partners, authorised signatories, and goods or services. Some of these are core fields and some are non-core, and the difference changes how fast the change takes effect.
What is the difference between core and non-core fields?
Core fields are the most important particulars, such as legal name, constitution of business, principal place of business and partners or directors. Changes to them need the proper officer's approval. Non-core fields, such as contact details, bank accounts, trade name and additional places of business, are generally filed and take effect without waiting for a decision. Check the portal's field labels, because the list is what governs.
How long do I have to file an amendment?
For non-core changes, file within 15 days of the change. For core changes, the rule works on the same basis but the officer must then approve the change, so file promptly. Late filing does not cancel the change, but it can attract questions and may affect your records.
Can I change my PAN or move to another state?
Not through a simple amendment. A change of PAN generally means the registration must be replaced, and moving the principal place of business to another State requires a fresh registration in that State. Plan these as new registrations, and cancel the old one once the new GSTIN is in use.
Can I change my legal name or trade name?
Yes. The legal name must match the PAN records of the business, so update the PAN side first if the name changed on that record. The trade name is a non-core field and is easier to change. Make sure invoices and e-way bills follow the updated name once it is approved.
How do I add an authorised signatory?
Use REG-14 and add the person in the authorised signatory section, with their PAN, Aadhaar-based details and contact information. The person must complete the required authentication. Remove people who have left as well, because they can still sign returns until you do.
Do I need a DSC to file REG-14?
You sign the application with a Digital Signature Certificate or through EVC, depending on the authorised signatory's registration. The person signing must be authorised on the registration, so the signatory update may need to be done first.
What documents do I need?
Keep proof for every change: a board resolution or partnership deed for changes in partners or directors, a rent agreement or ownership record and recent utility bill for addresses, a bank statement or cancelled cheque for bank accounts, and PAN or incorporation documents for name changes. Keep a scanned copy with the ARN the portal gives you.
How long does approval take?
Non-core changes often show as updated quickly after filing. Core changes depend on the officer's workload, and the officer may raise queries first. Track the application under Services → Registration → Track Application Status, and check the notices section for any query.
What if the officer rejects my amendment or raises a query?
Read the query carefully and answer each point with a document. If the answer needs a fresh filing, file it in the same form. Keep a record of each reply, because the officer may ask for them later in a scrutiny or audit.
Does an amendment affect my past invoices?
No, your past invoices remain valid. Use the updated details from the date the amendment takes effect. Where a name or address change is important for a supply, document the change and keep the approval order with your records.
