GST Modification and Amendment Services
GST Modification refers to updating or amending your registered business details on the GST portal when there is any change in business structure, address, ownership details, contact information, authorized signatory, bank details, or business activity. It is important to keep GST records accurate to avoid compliance issues, GST notices, return filing problems, Input Tax Credit (ITC) mismatch, and legal penalties.
Whenever there is a change in business details after GST registration, the taxpayer must file an Application for Amendment of Registration on the GST portal. This amendment is generally filed through Form GST REG-14.
Common GST modifications include:
- Business Name Change (without PAN change)
- Change in Principal Place of Business Address
- Addition or Removal of Partners / Directors
- Change in Authorized Signatory
- Mobile Number and Email Update
- Bank Account Details Update
- Addition of New Goods / Services (HSN / SAC Codes)
- Additional Place of Business Addition
- Business Activity Modification
- Change in State-Specific Registration Details
The GST portal classifies amendments into Core Fields and Non-Core Fields. Core fields such as legal name (without PAN change), principal place of business within the same state, additional place of business, and addition/deletion of partners or directors usually require GST officer approval. Non-core fields like bank details, email, mobile number, HSN codes, and authorized signatory are generally auto-approved after submission. Officer approval for core field amendments is normally processed within 15 working days.
The application for amendment should generally be filed within 15 days from the date of the change. GST official guidance also states that amendment cannot be used for PAN change, change in constitution resulting in PAN change, or shifting business from one state to another—in such cases, fresh registration is required.
For example:
- PAN change → Fresh GST Registration Required
- Constitution change causing PAN change → Fresh Registration Required
- Business shifting to another state → Cancel old GST and apply for new GST registration in the new state
Recent compliance updates also require valid bank account details to be properly updated, and GST portal controls have become stricter in 2026 for filing returns and maintaining compliance.
