Goods and Services Tax, also known as GST, was introduced by the Government of India on 1 July 2017 to simplify the tax structure on various commodities. The aim of the GST is simple – one nation, one tax, one market, and replaces several central and state-levied taxes such as excise, VAT and service tax.

Under the GST Act, businesses and individuals have to register their business with the state authorities and obtain a unique 15-digit GSTIN.

What is GSTIN Number?

GSTIN, short for Goods & Services Tax Identification Number is a 15-digit, state, PAN, and entity-based unique identification number associated with your firm or name once you have registered under the GST regime in India.

The GSTIN Number is used for various GST-related procedures, such as filing returns, claiming input tax credits and paying taxes.

  • The first 2 digits are reserved for the GST state code as per the Indian Census. Indian states or union territories are assigned unique codes (01-35). For example, “29” is the state code for Karnataka (KA).
  • The following 10 digits “ABCDE1234F” represent the PAN number of the business entity or the taxpayer.
  • The thirteenth digit number “2” is the registrations done by the firm within the state using the same PAN number. It can be an alphanumeric figure (between 1-9 and then A-Z)
  • The fourteenth is the default alphabet ‘Z’
  • The fifteenth digit “5” will be a check code, which can be a number or an alphabet.

Since every GSTIN number follows this structure, it is easy for you to check the authenticity of the business. GSTIN is public information, and technology has made it easy to verify GSTIN, which is crucial before doing any business dealings.

Why GSTIN Number is Required?

Operating your business legally in India requires a GSTIN number. This applies if your business’s annual turnover exceeds Rs. 40 lakh (or Rs. 10 lakh for Northeast states). Registering for GST and obtaining a GSTIN helps you avoid penalties and fines.

Here are some reasons why you must know how to get a GST number online.

1. Filing GST Returns

A GST number is required to file GST returns, which are periodic statements of a registered person’s transactions and tax liability. Filing GST returns is mandatory for every GST-registered person, even if there is no business activity or tax liability in a given period.

2. Claiming Input Tax Credit

A GST number is also necessary to claim the input tax credit, which is the amount of GST paid on the goods or services purchased for business purposes. Input tax credit claim is likely for a GST-registered person only if the supplier has uploaded the invoice details in the GST portal and the GST number of the buyer is mentioned on the invoice.

3. Avoiding Penalties

A GST number is also important to avoid penalties for non-compliance with the GST Act. If a person is liable to register under GST but fails to do so, he or she may face a penalty of 10% of the tax due or Rs. 10,000, whichever is higher. Similarly, if a person collects GST from customers but does not deposit it with the government, they may face a penalty of 100% of the tax amount.

Tip: Before you start filing your GST returns, you need to know your liability. You can calculate GST online under different GST rate slabs for your business with Razorpay’s GST Calculator
