What Is GST?

How Does it Work?

GST stands for Goods and Services Tax. Introduced on 1st July 2017, it is an indirect tax that replaced the existing myriad of taxes in the country, such as Value Added Tax(VAT), Service Tax, Purchase Tax, Excise Duty, and more!

Until the introduction of GST, different states in India levied variable taxes according to their policies. The Govt of India introduced GST to create a uniform, central taxing mechanism for businesses. Since then, businesses across the length & breadth of the country have registered with GSTIN to function.

Learn about what GSTIN is and how does it work in India.

What Is GSTIN?

GSTIN, or Goods and Services Tax Identification Number, refers to a 15-digit unique alphanumeric code that is assigned to a business for tax purposes. GSTIN replaced the Tax Identification Number[TIN] that was previously allotted to businesses under the VAT system.

The GST council maintains a data-rich repository of GST data that specific platforms can access through APIs known as GST Suvidha Providers (GSPs). Businesses can leverage the APIs exposed by the GSTIN for various use cases spanning lending, logistics, payments, etc. These include:

Public APIs  that can be used by anyone and require no consent

Consent APIs  that provide confidential information and require consent

Learn about the structure of GSTIN with an example

What is the Structure of GSTIN?

GSTIN has been uniquely constructed using a combination of factors. Let’s understand it using an example.

1st-2nd: State code; each state has its own custom code. For example, Delhi has 07 while Karnataka has 29.

3rd-12th: PAN of the person who pays the tax

13th: Entity/Registration Number. Refers to the number of registrations in the state of the taxpayer who pays the GST. If they register once, it’s 1. If the same legal entity registers again, it’s 2.

14th: ‘Z’ by default

15th: Check code that’s alphanumeric
