The Indian government launched the Goods and Services Tax (GST) on 1 July 2017 to simplify India’s tax structure. The main aim of implementing it was one nation, one tax, one market. GST has replaced a dozen central and state-levied taxes such as excise, VAT, and service tax.

Business entities need to register under GST and obtain a unique 15-digit Goods and Services Tax Identification Number (GSTIN). This has replaced the Tax Identification Number (TIN) allotted to businesses by state tax authorities for registering under the VAT system.

Under GST, all registered taxpayers will be consolidated onto a single platform for compliance and administration purposes and will be registered under a single authority.

What a GSTIN looks like

GSTIN, an abbreviation for Goods and Services Tax Identification Number, consists of a distinct 15-digit identification code allotted to each taxpayer (mainly dealers, suppliers, or any business entity) registered under the GST regime.

Here is what the 15-digit GSTIN indicates:

  • The first two digits represent the state code according to the Indian Census of 2011. Every state or union territory has a unique code. For example, 27 stands for Maharashtra and 09 is for Uttar Pradesh.
  • The next ten digits are the PAN card of the taxpayer or business house.
  • The 13th digit indicates the number of registrations in a state for the same PAN. It is alpha-numeric (first 1-9 and then A-Z).
  • The 14th digit is the alphabet ‘Z’ by default.
  • The last digit is a check code to detect errors. It can be an alphabet or a number.

GST Number Example

If a legal entity or business firm holds only one registration in a particular state, the 13th digit of its GSTIN will be designated as "1" in the format. If the same entity obtains an additional or second registration in the same state, the thirteenth digit will be marked as "2."

Likewise, if the entity acquires 11 registrations in the same state, the letter "B" will be allocated as the 13th digit of the GSTIN. This system allows any legal entity to have up to 35 business verticals registered within a state.

Why do you need a GSTIN?

A GSTIN is required for various reasons, such as:

  • To comply with the GST laws and regulations in India. A business that has an annual turnover of more than Rs. 40 lakh (Rs. 10 lakh for some states) must register for GST and obtain a GSTIN. Failing to do so may result in penalties and fines.
  • To claim the input tax credit (ITC) on the GST paid on purchases and expenses. A business can reduce its tax liability by claiming ITC on the GST paid on goods and services used for its business purposes. However, to claim ITC, the business must have a valid GSTIN and file its GST returns on time.
  • To issue GST-compliant invoices to customers and suppliers. A business must mention its GSTIN on every invoice it issues or receives, along with other details such as the invoice number, date, amount, GST rate, etc. This helps in tracking the transactions and ensuring tax compliance.
  • To file GST returns and pay taxes online. A business must use its GSTIN to log in to the GST portal and file its monthly, quarterly, or annual GST returns, depending on its turnover and type of registration. The business must also use its GSTIN to pay the taxes due online through various modes such as net banking, debit card, credit card, etc.

GST registration is critical for business entities to avail various benefits available under the GST regime. The government has made it mandatory for businesses with an annual turnover exceeding Rs. 20 lakh to have a GSTIN. If you are a registered dealer, you need to file GST returns and pay if GST liability exists. Also, if the GST you pay is more than the GST liability, you can claim a refund through your GSTIN.

A GSTIN also helps when you are looking to avail a loan to fund your business. Financiers such as Bajaj Finance provide business loans to buy inventory, expand commercial space, and grow their trade. Your business should be registered with the Government of India and have a valid GSTIN to be eligible for a business loan.
