Goods and Services Tax (GST) is applicable in India from 1st July 2017. Under the new GST regime, nearly 1.4 crore businesses in India have obtained GST registration. All entities having GST registration are required to file GST returns every month. GST return filing is mandatory for all entities having GST registration, irrespective of business activity or sales or profitability during the return filing period. Hence, even a dormant business that obtained GST registration must file a GST return.

Businesses that are registered under GST must file the GST returns monthly, quarterly, and annually based on the business. Here it is necessary to provide the details of the sales or purchases of the goods and services along with the tax that is collected and paid. Implementation of a comprehensive Income Tax System like GST in India has ensured that taxpayer services such as registration, returns, and compliance are in range and perfectly aligned.
