Goods and Services Tax (GST) is a destination-based tax that is levied on the final consumption of goods and services. It aims to replace existing indirect taxes and provide comprehensive and continuous chain of tax credits. Key advantages of GST include a unified common market, simplified tax regime, reduced compliance costs, and elimination of cascading taxes which can potentially lower prices and boost growth. Registration for GST involves filing applicable forms online along with required documents such as business registration certificates and address proof. Existing taxpayers obtain provisional GST login credentials from the tax authority website before completing the enrollment process on the GST portal.
