Amend GST Registration explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Non-core GST fields — bank account, goods and services, business activity and secondary contact details — are amended on the GST portal through Services → Amendment of Registration Non-Core Fields. These changes are auto-approved on submission with DSC or EVC, without any officer verification.
Overview
The GST law splits registration particulars into core fields (which need officer approval) and non-core fields (which are self-service and auto-approved). Most routine updates — adding a bank account, updating HSN/SAC of goods and services, or business activity — fall under non-core fields and take effect immediately.
When It Is Required & Legal Basis
Section 28 of the CGST Act, 2017 with Rule 19 of the CGST Rules, 2017 governs amendments. Rule 19(1) proviso provides that changes to fields other than the notified core fields do not require the officer's approval. Non-core fields include bank account details, details of goods/services supplied, business activity, and details of stakeholders/authorised signatories (other than primary email/mobile).
Step-by-Step Process
- Log in and open the amendment. Visit www.gst.gov.in → Services → Registration → Amendment of Registration Non-Core Fields.
- Select the relevant tab. Choose Bank Accounts, Goods and Services, Business Details (business activity), or Authorised Signatory.
- Edit the particulars. For a bank account, add the account number, IFSC and account type, then upload a cancelled cheque, passbook or bank statement.
- Enter reasons and date. Fill the "Date of amendment" and "Reason for amendment" where prompted.
- Verify and submit. Tick the declaration, select the authorised signatory and submit with DSC (companies/LLPs) or EVC.
- Auto-approval. An ARN is generated and the amended certificate is updated instantly — no officer action is needed.

Filed on Form GST REG-14. No government fee applies.
Timeline & Due Dates
Non-core amendments are effective immediately on submission. Bank account details must be furnished within 30 days of the grant of registration, or before filing the first return (GSTR-1/IFF), whichever is earlier, as per Rule 10A of the CGST Rules.
Penalty for Delay / Non-compliance
Not furnishing bank details within the Rule 10A window can lead to system-driven suspension of registration. A general penalty under Section 125 (up to ₹25,000 CGST + ₹25,000 SGST) applies for other non-compliance with the amendment requirement.
Practical Tips
- Add your bank account as soon as the account is opened — suspension for missing bank details is common.
- Keep the HSN/SAC list aligned with what you actually supply; it feeds e-invoicing validations.
- Non-core edits are instant, so double-check the IFSC and account number before submitting.
- If a field you want to change is greyed out, it is a core field — use the core amendment path instead.
