Goods and Service Tax or GST refers to the indirect tax regime introduced in July 2017, replacing India’s massive and complex consumption tax regime with a simple, manageable, uniform and centralized one.

Strictly speaking, it is a consumption tax charged on goods and services availed by 1.3 billion Indian consumers.

Although GST is charged to consumers, it reaches the government through the providers of goods and services, i.e. businesses and companies. Therefore, businesses are required to register for GST.

What is GST?

Goods and Service Tax (GST) is a tax levied on the domestic consumption of goods and services. It is an indirect tax regime that came into force on 29 April 2017, replacing the VAT structure.

The most prominent feature of GST that distinguishes it from the older tax regime is that it establishes a uniform, centralized, transparent and manageable tax structure that prevents tax on tax (cascading effects of taxes).

It establishes one indirect tax for the whole country by incorporating taxes like excise duties (central and state), additional customs and excise duties, surcharges, State VAT, service tax and sales and purchase taxes.

Under the GST Act, the ibid taxes were simplified and subsumed within only three types of taxes which are also known as the components of GST:

  1. Central Goods and Service Tax (CGST): Levied by the union government on intra-state transactions, that is, sales within a particular state, say West Bengal.
  2. State Goods and Service Tax (SGST): Charged by the State governments on intrastate transactions.
  3. Integrated Goods and Service Tax (IGST): Exacted by the Central Government on inter-state transactions, that is, trading between states, say between West Bengal and Bihar. Taxes collected from IGST are divided between the union and the state government (consuming state and not the selling state) according to the rates specified by the Government of India.

To determine the GST rates, a GST council has been established by the Government of India. It comprises 34 members (mainly finance ministers of each state) and is spearheaded by the Union Finance Minister.

There are five tax slabs into which goods and services are divided- 0%, 5%, 12%, 18% and 28%. At present, most goods fall within the 18% tax range. This starkly contrasts the previous regime in which the average tax levied on goods used to be 26.5%.

However, certain goods and services have not been incorporated within the GST regime and are taxed as per the previous tax structure by individual state governments. These include petroleum products, electricity and alcohol.

What is GSTIN?

A Goods and Service Tax Identification Number (GSTIN) is a unique identification number of 15 digits provided to businesses or companies registered under the GST regime.

During the pre-GST regime, these businesses, dealers, or suppliers had to register under the State VAT law and were given a unique PAN-based Tax Identification Number. On the other hand, a Service Tax Registration Number was allotted to the service providers by the Central Board of Excise and Customs (CBEC).

However, under the GST regime, all the ibid mentioned taxpayers had been brought into a single platform by providing them with a unique state PAN-based identification number. This makes tax administration much more straightforward and transparent.

The structure of the GSTIN is as follows:

  1. A unique state code allotted by the Indian Census, 2011 is denoted in the first two digits.
  2. The next ten digits denote the PAN number of the taxpayer.
  3. The thirteenth digit is the registration number assigned to the taxpayer by the state.
  4. The fourteenth digit is Z by default.
  5. The last digit is for the check code, a number or an alphabet.

A dealer or supplier may open the Online GST portal or visit a GST Seva Kendra set up by the union government for GST registration.

According to the Government of India, the following people must apply for GST registration:

  1. Businesses having an income of over 40 Lakh.
  2. Dealers or Suppliers registered under pre-GST law.
  3. Companies that supply their products through e-retailers.
  4. All E-Retailers.

Main Differences Between GST and GSTIN

  1. Both terms relate to India’s new indirect tax system but serve different purposes. GST refers to the new indirect tax that unites the entire county under a single tax system.
  2. The main difference between GST and GSTIN is that the former refers to the entire consumption tax system, while the latter is one of the instruments that make the system workable.
  3. GST is imposed on the purchasers of goods and services. But it is exacted by the government from the suppliers, retailers and service providers with a unique identification code, the GSTIN.
  4. The GST Council determines the GST rates of goods and services constituted by the Government of India. At the same time, the  GSTIN of the millions of taxpayers is managed by the Goods and Service Tax Network-the organization that controls the IT system of the entire GST portal.
  5. One of the main advantages of GST is that it has helped reduce the cost of most goods and services, especially by eliminating excise duty on inter-state trade and thus obliterating tax on tax. GSTIN, on the other hand, has made tax filing easy for businesses or companies and helped them avail themselves of business loans and other benefits provided under the GST regime.
