GST introduced in 2017 was implemented to replace most of the existing taxes to create a structured and centralized taxation policy all over the country, simplifying the way taxes are levied on businesses. Operating a business or being liable for registration but not filing your GST returns on time can lead to a heavy penalty and even be registered as a criminal offence.

Having a GST number and filing GST is mandatory for you if you are a business or an individual who sells goods, and the annual turnover limit is over Rs 40 lakhs in normal category states and over Rs 20 lakhs in special category states. Meanwhile, the threshold limit for services is over Rs 20 lakhs for normal categories and over Rs 10 lakhs for special categories. In this blog, we will cover everything you need to know about how to get a GSTIN number in India.

Meaning of GSTIN Number

GSTIN is the abbreviation for Goods and Services Tax Identification Number. It is a 15-digit alphanumeric code assigned to every taxpayer registered under the GST regime.

GSTIN is a unique identifier that helps the tax authorities track the tax transactions of different businesses nationwide.

A GSTIN has five parts: the initial two digits are the state code, the following ten digits are the PAN of the taxpayer, the thirteenth digit is the entity code number of registrations on that PAN in that state, the fourteenth digit is the default letter Z, and the fifteenth digit is an alphanumeric check code.

For eg: The GSTIN of Razorpay is 29AAGCR4375J1ZU, where

  • 29 refers to the state code,
  • AAGCR4375J is the PAN of the company/business,
  • 1 is the entity code number of registrations on PAN in the state,
  • Z is the default letter, and
  • U is the alphanumeric check code.

GSTIN replaced the previous tax identification numbers, such as TIN, Service Tax No, etc., used under the different indirect tax laws before GST was implemented.

Every business liable to register under the GST Act must obtain a GSTIN for each state or union territory from which it operates. This number is important for businesses as it enables them to file GST returns, claim input tax credits, issue GST invoices and comply with the GST rules and regulations.

Who Should Apply for GSTIN Number?

As per the GST laws, it is mandatory to register for a GSTIN if:

  • Any business with an aggregate turnover over Rs. 40 lakh (for normal category states) or over Rs. 20 lakh (for special category states)
  • Any individual has an annual income exceeding Rs. 20 lakh (for normal category states) or exceeding Rs. 10 lakh (for special category states)
  • Any business entity or e-commerce company operating in India must have a GST Registration.
