GST registration form fields: mandatory disclosures and verification requirements structure tax registration and record serviceability. The GST registration form standardizes applicant disclosures with sequential fields covering identification, business commencement and tax liability dates, scheme elections including Compounding Scheme, and mandatory date ranges for casual and non-resident dealers. It requires prior registration details for existing registrants, designation of the Principal Place of Business for service and records, full bank account disclosure, top goods/services, additional places of business, responsible persons by constitution, authorized signatory and representative, state-specific information, scanned supporting documents, and a verification declaration; the form is designed for online validation on a common portal.
