GSTIN: What Is It, Format And Example Of The 15-digit GST Number - Forbes India (1)

GST is a household term in India, not just because it’s a tax levied on most goods and services, but because it’s a relatively new phenomenon that also attracted controversy. But there’s more to it than its oft-repeated controversies. Like GSTIN.

The Goods and Services Tax Identification Number (GSTIN) is a unique identification number provided to firms in India that are registered under the Goods and Services Tax (GST) system.

Significant changes have been made to the Indian taxation system as a result of the implementation of the GST, which has simplified the tax collecting and compliance processes. Businesses must register for GST and get a GSTIN to comply with laws and reap the benefits of the GST system.

Nonetheless, as the number of firms registering for GST continues to rise, it has become vital to check the legitimacy of GSTIN to prevent fraudulent actions.

In this article, we will explore in depth what GSTIN is, how you should apply for a GSTIN, and how to check its legitimacy, assuring a compliant and efficient business operation under the GST regime.Also Read: Income tax slabs in India 2023-24: Old vs new tax regime, deductions and more

What is GSTIN?

GSTIN (Goods and Services Tax Identification Number) is a unique identifier granted to firms in India that are registered under the Goods and Services Tax (GST) regime. It is a 15-digit alphanumeric code used for a variety of GST-related procedures, including submitting returns, obtaining input tax credits, and making payments. The GSTIN identifies the taxpayer and allows the GST system to follow their transactions.

The first two digits of the GSTIN signify the state code, followed by ten digits of the business's PAN (Permanent Account Number), followed by the entity code and the check digit. Businesses must obtain a GSTIN to comply with India's GST legislation and regulations. Since the 2017 adoption of the Goods and Services Tax (GST), the GSTIN has become required for conducting business in India.

GSTIN structure simplified

Here’s another look at the structure of a GSTIN:

Character Meaning
First two digits State Code
Next 10 digits PAN allotted to the business
13th digit The number of registrations in a state
14th digit Default character
Last digit Checksum digit or number

  1. Registrations in the state are represented by the 13th digit. It's a combination numeric/alphabetic code, with digits 0 through 9 preceding the letters A through Z.
  2. The 14th digit is a default that is determined by the type of company. The letter Z is used to indicate a typical taxpayer.
  3. The GST department grants a GST Number to an NRTP (non-resident taxable person) who doesn't have a Permanent Account Number. Therefore, the following 10 digits of GSTIN would be the foreign government's tax identification number.

The example of a GSTIN would go like this: 22AAAAA0000A1Z5, where 22 is the state code, which is Chattisgarh, AAAAA0000A is the PAN or the Personal Account Number, 1 is the entity number of the same PAN holder in a state, Z is the default alphabet and 5 is the checksum digit.

What is the importance of GSTIN?

Under GST regulations, a business must know its GST number in India, as this is the number that must be included on every invoice from a supplier to receive the correct amount of input tax credit.

Businesses should also collect customers' GST numbers and include them on invoices since these are required for customers to claim input tax credits.

In a nutshell, obtaining a GST number in India is a necessary step for any company. This will aid enterprises in maintaining their market credibility and claiming the right input tax credit.

Who should register for GST?

Under the Goods And Services Tax (GST), all businesses that have a turnover exceeding the threshold limit of INR 40 lakh or INR 20 lakh or INR 10 lakh, depending on the area of operation, must register as a normal taxable person
