GST registration amendment: update core and non-core details online; officer approval required for core changes.
Amendments to GST registration are processed via the GST portal as either core field or non-core field changes. Core fields-legal business name (without PAN change), principal/additional places of business, and changes to partners, directors or authorized signatories-require supporting documents and officer approval; non-core updates like contact or bank details update immediately online. PAN changes require obtaining a fresh GST registration. Submissions must use DSC for companies/LLPs or EVC/OTP for proprietorships and generate an Application Reference Number for tracking.
