The Indian government implemented Goods and Services Tax, on March 29, 2017, whereas the GST Act started from July 1, 2017. GST is an all-inclusive indirect tax brought in to make the indirect taxation structure of India more streamlined by amalgamating multiple subsidiary taxes like excise duty, value-added tax, and service tax under one single integrated taxation system. There would be one tax levied from the manufacture to the ultimate consumer on all products and services under a GST system. The facility of input tax credits is available at each step of production and distribution. Therefore, companies can use this facility to set-off tax they have paid on inputs and thus reduce their effective tax liability. Since all the earlier stages of the supply chain derive set-off benefits for the input taxes paid, the GST applies only to the value added by the final dealer to the end user. This plan is aimed at establishing more balanced tax system among the states and reducing the cascading effect of taxes. The structure of GST looks toward reducing interstate tax inequities, enhancing tax compliance, and widening the revenue base toward forming a much more efficient and transparent indirect tax system in India. This study demonstrates the financial and accounting activities carried out by a CPA business, with a focus on GST.
