GST registration is mandatory for businesses in India that cross the turnover threshold or fall under specific categories such as e-commerce sellers, interstate suppliers, or service providers. Having the right documents ready ensures a smooth and quick registration process. In 2025, the GST portal requires both business-related and personal documents to verify authenticity before issuing a GSTIN (Goods and Services Tax Identification Number).
