The switch to the GST (Goods and Services Tax) regime transformed the taxation system and economy of India drastically. The GST regime helped to bring several different taxes under one umbrella, making the process of tax payment more straightforward. However, the GST regime requires dealers to file their returns on time to ensure compliance. All registered dealers must file a GSTR 1 (Goods and Services Tax Return) every month. Such a return contains valuable information regarding outward supplies made, and individual dealers have the option of filing their GSTR 1 every quarter.
