Company GST Registration in India: Complete Guide for Businesses

GST registration is a legal requirement for many companies operating in India. It allows businesses to collect Goods and Services Tax (GST) from customers, claim input tax credit, and operate in compliance with Indian tax laws. This guide explains who needs GST registration, eligibility rules, required documents, registration steps, and post-registration compliance, backed by official sources.

What Is Company GST Registration?

GST registration is the process through which a business obtains a GST Identification Number (GSTIN) from the Government of India. GSTIN is a 15-digit unique number issued under the Central Goods and Services Tax Act, 2017. Once registered, a company becomes legally authorized to charge GST on taxable supplies and claim input tax credit on purchases.


Who Is Required to Register for GST?


A company must register for GST if it meets any of the following conditions:

1. Turnover-Based Requirement

  • Businesses supplying goods must register if annual turnover exceeds ₹40 lakh

  • Businesses supplying services must register if annual turnover exceeds ₹20 lakh

  • For special category states, the threshold is ₹20 lakh (goods) and ₹10 lakh (services)


2. Mandatory Registration (Regardless of Turnover)

GST registration is compulsory for:

  • Companies involved in inter-state supply

  • E-commerce sellers and operators

  • Casual taxable persons

  • Non-resident taxable persons

  • Businesses liable to pay tax under reverse charge

  • Input Service Distributors (ISD)
