GST was introduced in India to simplify the indirect tax system in the country. It unified a plethora of state and central taxes to form a unified integrated tax that aimed to reduce the burden of the cascading effect of taxes on the consumer.

According to the GST law, all businesses supplying goods and services whose annual turnover crosses a particular limit specified under the law are compulsorily required to register under GST and follow the rules and procedures of compliance as required under the law.

The GST number (GSTIN) is a unique identification number provided to firms registered under the goods and services tax system. The businesses must register and get their GSTIN for compliance and to enjoy the benefits of the GST system. The registration process involves submitting an online application on the GST portal, providing details about the business, and obtaining the unique GST number. This number is mandatory while paying taxes, filing returns periodically, claiming input tax credit, and other compliance-related activities.

What is GST Number (GSTIN)?

GSTIN (goods and services identification number) is a fifteen-digit alphanumeric code that is required for submitting returns, claiming input tax credit, and making payments. It is an identifier for the taxpayer and also helps the tax authorities monitor the transactions of the taxpayer. Businesses can voluntarily opt for the GSTIN even when their turnover does not cross the threshold limit. Taxpayers also have the option to obtain different GSTINs for their multiple businesses, provided certain conditions are satisfied as specified under the law.

Importance of GSTIN

The GSTIN is important and has to be included in every invoice of the supplier. It is required for the following:

  • Availing input tax credit (ITC): Input tax credit is the credit received for the tax paid by the supplier on the purchase of goods or input of services in the course of business. This credit helps reduce the tax liability of the supplier on his outward supplies.
  • Filing GST returns: Various GST returns are required to be filed as per the GST Act, on a monthly, quarterly, and annual basis. The GST number is mandatory to file the returns.
  • Claiming Refunds: Refunds need to be claimed under various provisions, such as exports, supplies to SEZ units, etc. A GST number is mandatory for claiming such refunds.
  • Mentioned in tax invoices, debit notes, and credit notes: The GSTIN of suppliers and recipients must be mentioned in tax invoices, debit notes, and credit notes. It will help the receiver of the goods and services avail the input tax credit.
  • Mandatory requirement: Businesses supplying goods and services are required to register under GST as specified under the law, and non-registration can lead to legal consequences. GSTIN is mandatorily required for all compliance activities, and all traders registered under GST must obtain the GST number after registering in the portal.
  • Enjoy the benefits of registration: Businesses registered under GST gain trustworthiness and competitive advantage. They gain a wider customer base and a credible online presence, apart from the main advantage of a reduction in tax liability due to input tax credit.
