GST Registration
Amendment
Core & Non-Core
Changed your business address, added a new place of business, updated your bank account, or changed constitution? GST registration must be amended within 15 days. TaxClue files the right amendment — core or non-core — correctly the first time.
Core vs Non-Core Fields — Know the Difference
All GST registration amendments are filed via Form GST REG-14 on the GST portal. However, the fields being amended determine whether the change is auto-approved (non-core) or requires officer review and approval (core). Filing the wrong category or misidentifying the field type causes delays and rejection.
Core Fields change the fundamental legal identity of your GST registration — PAN, legal name, constitution, promoters/directors, state jurisdiction. These require officer approval within 15 working days. Non-Core Fields are operational details — address (same state), bank account, additional places of business, authorised signatory, contact details, HSN/SAC codes. These are effective immediately on submission.
File Within 15 Days of Any Change — No Grace Period
Section 28(1) of the CGST Act requires every registered person to inform the GST department of any change in information furnished at the time of registration within 15 days of the change. Operating with incorrect registration details can affect your refunds, ITC claims, invoice validity, and e-way bill generation.
Core Field Amendments — What to Expect
