What is GST Registration?
Goods and Services Tax (GST) registration is the process by which a taxpayer gets a unique 15-digit Goods and Services Tax Identification Number (GSTIN) from the tax authorities. It is mandatory for businesses exceeding the prescribed turnover thresholds, inter-state suppliers, e-commerce operators, casual taxable persons, and those required to pay tax under reverse charge. It enables legal collection of tax from customers and availment of input tax credit.
