The Goods and Services Tax (GST) is a value-added tax levied on most goods and services in India.

The GST regime in India is divided into two components: Central GST (CGST) and State GST (SGST). The SGST is levied by the state governments, and each state has a unique GST state code. In this essay, we will discuss the GST state code for Chennai.

A GST state code is a unique two-digit code assigned to each state in India. It is used to identify the state to which the GST tax collected on a particular transaction belongs. The GST state code for Chennai is 33.

Understanding the GST State Code for Chennai: The GST state code for Chennai is an important identifier for businesses operating in Chennai.

  1. GST Registration: Every business with a turnover of over Rs. 20 lakh (Rs. 10 lakh for northeastern states) is required to register for GST. As per the GST registration process, businesses have to enter their state code, which, in the case of Chennai, is 33.
  2. GST Return Filing: GST-registered businesses in Chennai have to file regular GST returns with the government. The GST returns require businesses to provide details of their sales and purchases, along with the corresponding GST state code, which, in the case of Chennai, is 33.
  3. Input Tax Credit: The GST regime allows businesses to claim input tax credit for the GST paid on their purchases. However, to claim input tax credit, businesses have to ensure that the GST state code on their invoices matches the state code of their GST registration in Chennai. For Chennai-based businesses, the GST state code is 33.
  4. GST Rates: The GST rates for goods and services vary depending on the nature of the product or service. However, the GST rates are consistent across India, and the GST state code does not affect the GST rate applicable to a transaction.

What Is the GST State Code to Be Used in Chennai?

Each state has a code number. A taxpayer who has business across multiple states will have multiple GSTN with the same PAN number. A state code makes it easier to identify the state of the GST registered entity even if the taxpayer remains the same. The first two digits of the registration number depict the state code the business belongs to.

The state code for Tamil Nadu is 33. Every GST registration in Chennai will have a GSTN beginning with 33. For example, the GST number of the ICICI Bank Chennai branch is 33AAACI1195H1ZT. Every business in Chennai has to mention the GST state code on the physical premises as well as the invoice.
