GST Registration: Step-by-Step Process and Requirements

What is GST Registration?

GST (Goods and Services Tax) registration is a mandatory process for businesses in India whose annual turnover exceeds the prescribed threshold limit. It's a unified tax system that replaced multiple indirect taxes and streamlined the taxation process across the country.

Under the GST regime, every registered taxpayer is assigned a unique 15-digit GST Identification Number (GSTIN) that enables them to collect tax from customers and claim input tax credit on their purchases.

Key Point: GST registration is not just a compliance requirement but also provides various business benefits including input tax credit and enhanced business credibility.
