GST Modification (also called amendment of registration) is the process of updating your existing GST registration details on the GST portal after registration. It helps keep your GST profile accurate when there are changes like business details, addresses, partner/director details, authorised signatory, or bank account information.
At CS, the team handles the end-to-end update process—right from checking what needs to be changed (core vs non-core), preparing documents, filing the amendment request, and completing verification using DSC/EVC.
Core vs Non-core
Core field changes generally require approval by the tax officer (example: legal name/trade name, principal place of business, additional place of business, and key stakeholder changes)
Non-core field changes are usually auto-updated after submission and do not require officer approval (example: authorised signatory details, many stakeholder detail edits, bank account updates).
Key Features of GST Modifications
Accurate Profile Updates
Keeps your GST registration details updated so invoices, refunds, and compliance activities aren’t affected by incorrect information.
Core & Non-core Handling
CS identifies whether the change is core (approval-based) or non-core (auto-update) and files accordingly.
DSC/EVC Submission
Amendment applications are verified and submitted using DSC or EVC based on eligibility and entity type.
ARN Generation & Tracking
After submission, an ARN is generated that can be used to track the amendment status on the GST portal.
Document-backed Updates
For certain updates (like address), supporting proof must be uploaded to avoid objections/rejection.
Compliance Confidence
Proper updates reduce mismatch issues and help maintain clean, verifiable business details for stakeholders.
