Value Added Tax (VAT)

VAT was introduced into the Indian taxation system from 1st April 2005.

VAT full form Value Added Tax is a tax on the value that gets added to a product at every stage of its production, from raw material to finished product. The term ‘Value added’ refers to increase in value of goods and services at each stage of production/transfer of goods or services.

Example: Suppose Mr. A owns a restaurant and spends Rs.25,000 towards obtaining raw materials. Input tax is 10%, so input tax becomes 10% of Rs.25,000 = Rs.2,500. Now after selling the food products made by using the purchased raw materials, Mr. A was able to make Rs.80,000. Supposing 10% output tax, output tax becomes Rs.8,000. So, final VAT payable by Mr. A comes out to be Rs.8,000 – Rs.2,500 = Rs.5,500.

VAT was applicable till 30th June 2017. From 1st July 2017 onwards GST was introduced into Indian taxation system.

Goods Service Tax (GST)

A taxable person like individual, company, firm, co-operative society, trust, etc who engages in economic activities (i.e. trade and commerce), who carries out any business at any place in India, should Register for GST under GST Act.
