GST Registration vs GST Return Filing | Complete Comparison

Difference Between GST Registration and GST Return Filing

GST Registration means the government will provide a GST number through which business can legally charge GST and do the business. GST return filing means regularly giving details of sales, purchases, and GST paid to the government. GST registration is usually done once, but GST return filing must be done every month, quarter, or year. Both are important to avoid penalties and follow GST laws properly.

 


What Is GST Registration?

Meaning and Legal Definition

GST registration is the process of registering a business under the GST Act, after which a unique GST Identification Number (GSTIN) will be provided. This number legally authorizes a business to collect GST from customers and claim input tax credit. 

Without GST registration, charging GST is illegal.

 


Who Needs GST Registration?

GST registration is mandatory if:

  • Over ₹40 lakh is turned over annually (₹20 lakh for services).

  • You’re engaged in inter-state supply

  • You sell through e-commerce platforms

  • You are either a non-resident or a casual taxable person.

You can verify official thresholds on the GST portal:

Types of GST Registration

Types of GST Registration in India

Different types of GST registration are available based on the nature of the business, turnover, and location under the Goods and Services Tax (GST) law. To ensure proper GST compliance and avoid legal issues it is important to choose the right type of GST Registration. The main types of GST registration in India explained below:

1. Regular GST Registration

This GST registration is the most popular registration.  It applies to businesses whose turnover exceeds the prescribed threshold or those required to register mandatorily. Businesses registered under this category can collect GST from customers and claim input tax credit (ITC).

2. Composition Scheme Registration

This type is meant for small businesses with lower turnover. Under the composition scheme, taxpayers pay GST at a fixed, lower rate and file fewer returns. However, they cannot claim input tax credit or collect GST from customers.

3. Casual Taxable Person Registration

This registration is for businesses that supply goods or services occasionally in a state where they do not have a fixed place of business, such as exhibitors at trade fairs. This registration is temporary and valid for a limited period.

4. Non-Resident Taxable Person Registration

This applies to individuals or businesses located outside India that supply goods or services in India. Such taxpayers must register under GST before starting operations in India.

5. GST Registration for E-commerce Sellers

All the businesses selling goods and services and e-commerce platforms such as Amazon and Flipkart need to get GST registration whatever their turnover. 

6. Voluntary GST Registration

Businesses with turnover below the GST threshold can choose voluntary GST registration. This helps them claim input tax credit and build credibility with customers and vendors.

What Is GST Return Filing?

Meaning and Purpose

It shows proper tax reconciliation and transparency. GST return filing is a system in which all the details such as sales, purchase, tax collected, and tax paid details are submitted to the GST department regularly.

In short, GST return filing tells the government:

“"These are my earnings, the tax I collected, and the amount I paid.”
