Advantages of GST

GST Removes the Cascading Effect of Tax

GST is a fundamentally a comprehensive indirect tax meant to bring indirect taxation under one umbrella. Moreover, it is designed to nullify the cascading impact of tax from the tax system that was put in place earlier.

The Provision of Composition Scheme for Small Businesses

Small businesses that yield a turnover between Rs. 20 Lakh to Rs. 75 Lakh can significantly benefit from the GST as they now have the option to lower their taxes through the Composition scheme.

Increased Threshold for Registration

Under the previous tax structure, businesses with a turnover of over Rs 5 lakh were susceptible to VAT. Keep in mind that this threshold would vary with each state. However, under the new GST system, this threshold has been increased to Rs 20 lakh, which benefits small traders and service providers.

Simple and Straightforward Online Procedure

The GST process from start to finish is done online, and it is easy to carry out.

This is particularly beneficial for small and medium-sized businesses, as the processing time to finish different registrations such as VAT, excise, and service tax can be quite long.

Defined Rules for E-Commerce Operators

The tax regulations around the supply of goods in the e-commerce sector were not well-defined under the previous tax structure.

Online merchants such as Flipkart and Amazon would have to file a VAT declaration and mention the registration number of the delivery truck. Tax authorities had the power to seize goods if these online merchants did not produce the required documents.

In some states like Kerala and Rajasthan, these merchants would be treated as facilitators or mediators and did not need to register for VAT. The difference in tax rules in different states under different circumstances would cause a massive amount of confusion.

Fortunately, the rules and provisions for the e-commerce sector have been clearly laid out under the new GST system, thereby drastically reducing the confusion.

Improvement in the Efficiency of Logistics

The logistics industry in India initially had to maintain multiple warehouses across states to evade Central Sales Tax (CST) and state entry taxes on the movement of goods between states.

However, the GST regulations have brought clarity on the movement of goods between states.
