GST Registration in India: A Step-by-Step Guide

The introduction of the Goods and Services Tax (GST) in India marked a significant transformation in the country’s indirect tax system. For businesses, GST registration is more than a legal requirement—it's a gateway to streamlined operations, tax credits, and nationwide compliance.

What is GST Registration?

GST registration is the process by which a business or individual registers under the GST Act to become a recognized supplier of goods and services. Once registered, a unique Goods and Services Tax Identification Number (GSTIN) is assigned.

Who Needs to Register for GST?

GST registration is mandatory for:

• Businesses with aggregate turnover above ₹40 lakhs (goods) or ₹20 lakhs (services).

• Special category states: Threshold is ₹20 lakhs for goods and ₹10 lakhs for services.

• Interstate suppliers regardless of turnover.

• E-commerce sellers, input service distributors (ISDs), and agents of a supplier.

• Businesses under reverse charge mechanism.

• Casual taxable persons and non-resident taxable persons.

Voluntary registration is also allowed for businesses below the threshold, often to avail of input tax credit (ITC).

Benefits of GST Registration

• Legal recognition as a supplier of goods/services
