The Goods and Service Taxation (GST) policy of India is a step to normalize the taxes applied on various goods and services. This would curb off the cascading effect of the taxes, and in turn bring out a better place for the customers and suppliers. It is expected to have a tax only on the value addition and no business costs for the procurement of inputs, raw material or input services.
When considered for an overall sale and purchase scenario, the amount of indirect taxes applied over the goods throughout the supply chain will reduce, and in turn reducing the cost of goods and services. At present VAT (Value Added Tax) is applied to the goods, which is administered by the state government. Hence, the VAT varies in each state; apart from which there are local taxes and duties that are levied. With the GST being brought in, the prices will be seen to be uniform throughout the country. Under GST, there will be four tax slabs – 5 per cent for essential items, 12 per cent and 18 per cent for standard goods and services, 28 per cent for luxury and sin tax items. The last category will also have an extra cess besides GST. Most food items will not be taxed at all.
As ascertained that most of the food items will have no tax, people would be able to get food at affordable rates; it may be seen as a step towards reducing hunger among the population of India.
The GST applied by the Indian government, even though proposing uniformity in taxes across the country, have set variable tax rates across various sectors. It is said that GST is the biggest tax overhaul in India after independence. Finance Minister Arun Jaitley after having a two-days meeting with his counterparts across the states, highlighted in one of his statements with the reporters, that there will be tax exempt on the Healthcare and Education services, whilst, luxury services like five-star hotels will be taxed at the rate of about 28%. 
The Health and education services getting tax exempt may have a direct positive impact on accomplishing SDG 3: Good Health and well-being; and SDG 4: Quality Education.

High taxes laid on telecom, financial services, is likely to slow down the planned rollout of infrastructure, mentioned Rajan Mathews, Director General of Cellular Operators Association of India. The GST may have a negative impact on the SDG 9: Industry, Innovation & Infrastructure which aims to have investments in these fields to in turn improve the economic growth of the country. The UNDP mentions that technological progress is a key to find steady solution towards economic and environmental challenges, for example providing new jobs and promoting energy efficiency.  Negative effect on the industry may sequentially effect partially the SDG 7: Affordable & Clean Energy; reducing job opportunities may bring down the effective performance of SDG 8: Decent Work and Economic. If the slowed down industrial growth, is said to effect the investment in scientific research and innovation, its consequence may be reflected on the climatic conditions as well; decelerating the performance of SDG 13: Climate Action.

By the introduction of GST, which has brought the whole country of 1.2 billion population under a single umbrella of taxation policies. Prime Minister Modi’s ideology with GST is to bring in more Foreign Investments as well, by making India a business friendly destination. This maybe a boost to the partnership goals set by the United Nations in the SDGs, i.e SDG 17.
Under the consumer rights policies, GST will be having a transparent taxation system. The government is putting efforts to create awareness among people for the proposed GST structure. The MRP based taxation will be eliminated, where earlier the customers were not aware of the break-up of the cost and taxes applied on it. Under GST, multiple taxes will also be eliminated (service tax and VAT), which prevails today.
According to the GST Council meeting held on 18th May, 2017, the government has also introduced ‘compensation cess’ which will be applied to products like tobacco, coal, aerated water, motor cars etc., which will be costing the customers to pay high. Sunil Sinha, chief economist of India Ratings mentioned that the GST implementation would surely be disruptive to the economy, as there are huge changes made in the supply chain; though it may be beneficial in medium to long term.
The GST being applied will be providing various business opportunities. People will have better accessibility to the goods and services. Masses will not be travelling to different states to avoid taxes or save upon it.
