What is GST?

GST, or Goods and Services Tax, is an indirect tax imposed on the supply of goods and services. It is a multi-stage, destination-oriented tax imposed on every value addition, replacing multiple indirect taxes, including VAT, excise duty, service taxes, etc. Goods and services are included under a single domestic indirect taxation law for the whole of India. In this regime, tax is charged at each point of sale.

History of GST (Goods and Services Tax)

GST was first implemented as a tax regime in 1954 in France and later adopted by several countries, including Australia, Canada, the United Kingdom, Spain, South Korea, Vietnam, Monaco, etc.

In India, the GST came into force in 2000 after a committee was set up by the then Prime Minister Atal Bihari Vajpayee, a task force. Headed by the finance ministry’s advisor, Vijay L. Kelkar, he concluded that GST could help improve the tax structure in India. In 2006, the Union ministry of finance proposed GST introduction from 1 April 2010. But, the Constitution Amendment Bill to facilitate the introduction of GST law was introduced in 2011. However, four supplementary GST bills were passed in Lok sabha and approved by the cabinet. Later, GST came into force on 1 July, 2017.

Upon implementation, the GST replaced the following central taxes:

  • Service tax
  • Duties of excise
  • Central excise duties
  • Cess and surcharge
  • Additional duties of excise
  • Additional duties of customs
  • Additional duty of customs

GST services also subsumed the following state taxes:

  • Entry tax
  • Purchase tax
  • Luxury tax
  • State VAT
  • Central sales tax
  • Entertainment tax
  • Taxes on advertisements
  • State cess and surcharges
  • Taxes on gambling and lottery

Note that taxpayers who have an annual turnover of up to Rs. 20 lakh can be exempted from the Goods and Services Tax. This cut off is at Rs. 10 lakh for special category states. The GST law also extended the option of choosing a compounding scheme and threshold exemption.

Meaning and objective of GST

GST definition states that it is a tax that has replaced multiple indirect taxes, like VAT, service taxes, excise, etc., in India. Notably, gaining an insight into the objectives of this tax regime helps to understand GST meaning better.

For instance, the primary objectives of the GST service tax include:

  • Elimination of the cascading tax effect: Under the GST bill, taxes are levied only on the net value-added portion, which eliminates the tax-on-tax regime and, in turn, lowers the cost of goods.
  • The subsumption of all indirect taxes: Except for a few, indirect taxes under the state and central government are subsumed into Goods and Services Tax.
  • Increase the tax to GDP ratio and revenue surplus: A high tax to GDP ratio indicates higher tax collections, a sign of a strong economic system. A wider tax base and increased tax compliance are more likely to result in higher revenue for the government through GST services.
  • Decrease corruption level and tax evasion: The GST bill aims to bring transparency in the tax system resulting in fewer instances of a false input tax credit.
  • Increase tax compliance: GST online aims to increase tax compliance, especially in small and unorganised businesses, by simplifying the GST platforms registration and returns filing process.
  • Increase in overall productivity and efficiency: The Goods and Services Tax in India aims to remove constraints regarding logistics and the lengthy claim process of an input tax credit. Also, by subsuming the entry tax, the overall productivity of enterprises is expected to increase.

Advantages of GST

The introduction of GST is touted as one of the biggest tax reforms in India. To know more about the impacts of GST, it is imperative to learn more about its advantages and disadvantages.

In this regard, the most prominent advantages of GST include:

  • Removal of the cascading effect of tax: The implementation of GST has brought indirect taxes under one umbrella, successfully eliminating the cascading tax effect and lowering the amount of compliance one must consider. For example, previously, service tax and VAT had their respective returns and compliance, but with the introduction of GST, entities only have to file one return. This, in turn, simplifies the process of inputting tax credit claims.
  • A uniform tax structure: GST has brought the entire country under one tax regime; it facilitates uniformity in processes, laws, and tax rates across India.
  • Simplified GST online process: All Goods and Services Tax processes can be initiated online, including registration and Goods and Services Tax return (GSTR) filing. This has simplified the process significantly and made it possible for start-ups to get registered with GST services without hassle in one place.
  • Regulation of the unorganised sector: The GST bill effectively streamlines the processes related to online compliance, payments, and claim processes. Further, it helps the unorganised sector, bringing them directly under the regulation of goods and service tax norms.
  • GST extends the composition scheme for all small businesses: Small businesses with an annual turnover up to Rs 1.5 crore (Rs 75 lakh for special category States) can become beneficiaries of GST’s composition scheme. The said scheme allows businesses to reduce their taxes.

Besides these, the GST bill has replaced 17 indirect taxes with one uniform tax. It has lowered the cost of goods and boosted demand for them, bringing in more revenue for both the centre and state governments.

Types of GST

There are four different types of GST, which are as follows:

  • State Goods and Services Tax (SGST): The state government charges SGST on intra-state goods and services transactions. Later, the revenue is collected by the state where the transactions in question were carried out.
  • Central Goods and Services Tax (CGST): The central government charges CGST on the intra-state transaction of goods and services. The concerned body is also responsible for collecting the revenue generated through this tax.
  • Integrated Goods and Services Tax (IGST): This GST tax is charged on inter-state transactions of goods and services and applied on imports and exports. Note that both centre and State share the revenue collected through IGST as per the GST bill.
    The state goods and service tax portion of this tax is collected by the state where the goods and services in question were consumed.
  • Union Territory Goods and Services Tax (UGST): This GST tax is levied by Union Territories and charged on all transactions carried out in any UT in India. It is similar in terms of payment rules on the GST platform and distribution.

GST rates slabs

In a broader sense, there are 4 GST tax slabs in India. GST rates have been structured to ensure that food items and essential services are kept in the lower tax brackets, while luxury items and services fall in the higher brackets.

GST calculation

How to calculate GST

In India, GST (Goods and Services Tax) is calculated as a sum total of GST payable on reverse charge, inward supplies, and output supplies. This total is derived individually for every month, and you will have to pay the amount calculated while filing GST returns every month.

As a taxpayer, you will have to consider all aspects and charges such as reverse charge, exempted supplies, inter-state sales, along with eligible, and non-eligible ITC, while calculating GST. Calculating the right GST amount will help you evade the 18% interest that will be levied if your payment falls short of your actual obligation.
You can also use the GST calculator available in the Government of India’s GST portal. It is to find out your total tax liability by filling in all the necessary amounts under the mentioned heads, such as return filing month, current ledger balance, tax liability under RCM, etc.

GST calculation formula

GST amount = (original price x GST rate) / 100
Net price = original price + GST amount
example: Say you are selling a commodity from Mumbai and sending it to Kolkata for Rs. 10,000, and the rate of GST applied on it is 12%.
The GST amount applicable for it will be (10,000 x 12) / 100 = Rs. 1,200; and the net price will be Rs. 10,000 + Rs. 1,200 = Rs. 11,200.

GST return filing

When to file GST returns?

Fundamentally, a GST return or GSTR is a document that has to be filed by taxpayers with the concerned tax administrative authority. This document comprises income/ sales or/ and purchase/ expense and proves useful in computing an entity’s tax liability.
Under the GST tax regime, registered dealers have to file GSTR, which includes:

  • Sales
  • Purchase
  • Output GST
  • Bank account details
  • Input tax credit

As per goods and service tax norms, regular businesses that have an annual aggregate turnover of more than Rs. 5 crore must file one annual return and two monthly returns, i.e., a total of 25 returns in one year at the online GST platform.

However, under the QRMP scheme, the number of Goods and Services Tax returns varies for those who file quarterly GSTR-1 filers. In that case, they have to complete a total of nine GST service tax returns in a year, inclusive of the annual return and GSTR-3B. Likewise, the number varies for special cases such as composite dealers, who must file GSTR five times a year.

New compliances under GST

In addition to filing goods and service tax returns online, the tax regime has also introduced multiple new systems.

  • E-way bills: This centralised e-way bills system was launched for inter-state movement of goods on 1 April 2018 and intra-state movement of goods on 15 April 2018. With the help of this system, traders, manufacturers, and transporters can easily generate e-way bills for transported goods.
    It is also beneficial for tax authorities and has helped decrease time at check-posts. Further, it has even been effective in reducing tax evasions.
  • E-invoicing: The GST bill system applies to businesses with an annual turnover of over Rs. 100 crore in the preceding fiscal year. Such businesses must obtain a unique invoice reference number for all B2B invoices by uploading them on GSTN’s online invoice registration portal.
    The said portal verifies the accuracy and authenticity of the invoice and subsequently authorises the businesses with a digital signature and QR code.
    The biggest advantages of e-invoicing include reduction of data entry error and a boost in inter-operability of invoices. The system helps transfer invoice information from IRP to the GST platform and e-way bill portal instantly. Plus, it eliminates the need to file GSTR-1 manually.
  • HSN code requirements: Businesses must mention their SAC/ HSN code on all supplies of goods or services on tax invoices from 1 April 2021. For example, B2B supplies for a registered entity with an aggregated turnover of up to Rs. 5 crore in the preceding year must mention their 4-digit HSN code on the invoice.
    Similarly, B2B or B2C supplies for registered entities with a turnover exceeding Rs. 5 crore in the preceding year have to mention their 6-digit HSN code on the invoice. Notably, any changes in mentioning 4/ 6-digit HSN or SAC code must be detailed under Table 12 of the GSTR-1 form.
