How to Update Business Details on the GST Portal (Amendment Guide, 2026)
Step-by-step guide to amending GST registration - change trade name, address, bank details, partners, or add new branches using Form REG-14 on gst.gov.in.
- Amendments split into core and non-core fields, and the split decides the timeline: non-core changes take effect immediately, core-field changes go to an officer who has up to 15 working days to approve.
- The path is gst.gov.in > Services > Registration > Amendment of Registration (Core or Non-Core Fields), and the form carries the same tabs as the original application. Submit with Aadhaar OTP, or DSC if you are a company or LLP.
- Three things cannot be amended at all: a PAN change, moving the principal place of business to another state (that needs a fresh GSTIN in the new state), and switching to composition, which goes through Form CMP-02 rather than REG-14.
- After approval, download the updated certificate from Services > User Services > View/Download Certificates — the old REG-06 stays on file until the amended one is issued.
To update business details on the GST portal: log in to gst.gov.in → Services → Registration → Amendment of Registration (Core Fields or Non-Core Fields) → select the field to update → make changes → submit via Aadhaar OTP or DSC → receive ARN → officer approves within 15 working days (for core field changes) or instantly (for non-core changes).
Not all business details can be updated the same way. Some changes (trade name, principal place of business, partners/directors) require officer approval. Others (additional places of business, bank account changes) are effective immediately on submission.
Core fields vs non-core fields: what's the difference?
| Type | Examples | Who approves | Timeline |
|---|---|---|---|
| Core field changes | Legal name, principal place of business, addition/deletion of partners or directors, change in business constitution | GST officer | 15 working days |
| Non-core field changes | Additional places of business, authorised signatories, bank details, HSN codes, goods/services description | No officer needed — auto-approved | Immediately effective |
Common business details you can update on the GST portal

Step-by-step: how to update business details on the GST portal
Step 1: Log in to gst.gov.in
Use your GSTIN and password. If you've forgotten the password, use the "Forgot Password" option — OTP is sent to the registered mobile or email.
Step 2: Navigate to Amendment of Registration
Go to Services → Registration → Amendment of Registration (Core Fields) for core changes, or Amendment of Registration (Non-Core Fields) for non-core changes.
Step 3: Select the tab with the field to change
The amendment form has the same tabs as the original registration: Business Details, Promoter/Partner, Authorised Signatory, Place of Business, Goods and Services, Bank Accounts. Navigate to the relevant tab.
Step 4: Make your changes
Edit the specific field. Upload supporting documents where required (e.g., new electricity bill for address change, new bank statement for bank account change).
Step 5: Submit with Aadhaar OTP or DSC
Submit using Aadhaar OTP (for proprietors, partnerships) or DSC (mandatory for companies and LLPs). An ARN is generated on successful submission.
Step 6: Track and download updated certificate
For non-core changes: the amendment is effective immediately. Download the updated GST registration certificate from Services → User Services → View/Download Certificates.
For core changes: track the ARN status under Services → Track Application Status. Officer approval takes up to 15 working days.
Documents required for common amendments
| Amendment | Documents needed |
|---|---|
| Change of address | New electricity bill (within 3 months) + rent agreement or NOC |
| Add new branch | Branch address proof (electricity bill + rent agreement/NOC) |
| Change bank account | Cancelled cheque or bank statement with IFSC and account holder name |
| Add/remove partner or director | PAN, Aadhaar, and photograph of new partner/director; resignation letter for outgoing party |
| Change legal name | Updated incorporation certificate or partnership deed showing the new name |
What changes cannot be made through amendment?
Certain changes are not possible via amendment and require cancellation and re-registration:
- PAN change — GST registration is PAN-linked. A PAN change requires fresh registration under the new PAN.
- State transfer — Moving your principal place of business to a different state requires new GSTIN in the new state. The old GSTIN must be surrendered.
- Change from regular to composition scheme — This is done via Form GST CMP-02, not REG-14 amendment.
Frequently Asked Questions
How do I update my business name on the GST portal?
To update your trade name: log in to gst.gov.in → Services → Registration → Amendment of Registration (Core Fields) → Business Details tab → update the trade name field → upload supporting document if required → submit via Aadhaar OTP or DSC → ARN generated → officer approves within 15 working days.
Can I add a new branch to my existing GST registration?
Yes. Adding an additional place of business is a non-core amendment — go to Amendment of Registration (Non-Core Fields) → Place of Business tab → add the new branch address and upload address proof. The change is effective immediately after submission.
How long does a GST amendment take to process?
Non-core amendments are effective immediately with no officer approval needed. Core field amendments (legal name, principal address, partners/directors) require GST officer approval within 15 working days. If the officer doesn't act within 15 days, the amendment is deemed approved automatically.
Can I change my GST registration from one state to another?
No. GST is state-specific. If you shift your business to another state, you need to cancel your existing GSTIN and register fresh in the new state. The new GSTIN will have the new state code prefix.
What is Form REG-14 in GST?
Form REG-14 is the application form for amendment of GST registration. It's filed on gst.gov.in to update core or non-core registration details. The same form handles both types — the system routes it to the correct approval workflow based on the field changed.
