Check Types, calculations for Sales Tax in India

Taxes are the sources of revenue for every government. Several kinds of taxes are imposed on common civilians for varied purposes. However, broadly there are two types of taxes in India, direct and indirect. In this article, you will know about an indirect tax: Goods and Service Tax (GST) in India. Keep scrolling to know more about it.

What is GST?

Earlier in India, different kinds of sales tax were imposed on  purchasing goods. However, on 1st July 2017, the Goods and Service Tax Act came into action and replaced all other types of sales taxes for both central and state governments. 

Goods and Service Tax (GST) is an indirect tax imposed on supply of  goods and services for domestic consumption. Consumers pay GST on the final price of a product. As the consumers pay GST, the sellers collect it and send it to the government. 

What Are the Types of GST?

GST is further classified into 4 types. Check out the detailed discussion on them.

State Goods and Service Tax (SGST)

As the name suggests, State Goods and Service Tax (SGST), is collected by the state government and is applicable for intra-state transactions. Therefore, this GST has a geographical boundary. SGST is applied to every good; however, alcoholic liquor does not come under SGST. Though every individual state has some policies to collect SGST, the internal structure remains the same.

Central Goods and Service Tax (CGST)

CGST is the tax imposed by the central government on intra-state goods and services. CGST has replaced all other types of taxes that were applicable earlier. Therefore, products within a state’s periphery are subject to two types of taxes, SGST and CGST. As the sellers collect the tax, they send the percentage to the two governments accordingly.ST is the tax imposed by the central government on intra-state goods and services. CGST has replaced all other types of taxes that were applicable earlier. Therefore, products within a state’s periphery are subject to two types of taxes, SGST and CGST. As the sellers collect the tax, they send the percentage to the two governments accordingly.

Integrated Goods and Services Tax or (IGST)

This tax is levied on the inter-state transactions of goods and services. Let’s understand it with an example. Suppose a seller from Delhi sells goods to a dealer in Odisha. Therefore, the transaction happens between two states, and IGST will be applicable in this case. IGST is first collected by the central government, and the state’s percentage is later given to the respective states.

Union Territory Goods and Service Tax or UTGST

The taxes are applicable to the transaction in Union Territories such as Andaman and Nicobar Island, Daman and Diu, Lakshadweep, Chandigarh, Dadra and Nagar Haveli. The percentage of SGST and UTGST is similar. Further, there is no legislation applicable to UTGST.

What Are the Objectives of GST?

The objectives of GST are as follows:

  1. One Nation, One Tax

There were different kinds of taxes levied on goods and services as indirect taxes. States and central governments had different tax percentages, and the rules regarding these were pretty complex. However, GST has replaced all these taxes and made the ideology of “One Nation, One Tax” applicable to India. 

  1. To Replace a Majority of Indirect Taxes in India

Before GST came, multiple taxes were applied to manufacturing and selling goods, such as excise duty, value added tax or VAT, service tax etc. Both central and state governments governed these taxes, and there was a lack of unified laws regarding tax collection. Therefore, the objective of GST was to merge major types of indirect taxes and make the process of law creation and tax collection easy. So, tax cascading has also been eliminated.

  1. To Control Tax Evasion

Another objective of GST was to curb tax evasion by enacting strict laws. Previously, laws on every indirect tax were not very strict; however, GST demands submitting proper invoices. This has made the tax-paying process fairer. Besides, it has also introduced a proper surveillance system.

  1. To Improve Distribution and Logistics

GST came to eliminate all the hassles regarding documentation of paying several taxes for manufacturing and selling goods. As a result, it improved the transportation cycle times and supply chain turnaround time. Besides, GST has an e-way bill system which helps in minimising higher warehousing and logistic costs.

How to Calculate GST?

GST calculation has several kinds of charges included, which are:

  • Reverse charge
  • Exempted supplies
  • Eligible and non-eligible ITC
  • Inter-state sales

Calculating GST correctly is very important as it removes the chances of an 18% penalty for not paying the right amount as your obligation. Therefore, the formula for GST calculation is as follows:

GST Amount = (Original Price X GST Rate)/100

Net Price = Original Price + GST Amount

Let’s understand it with an example. A manufacturer sells a good worth Rs. 15,000, with a GST rate of 12%. Therefore, the GST Amount payable will be

(15000X12)/100 = 1800

And the net price of that good will be (15000+1800)= Rs. 16,800
