How to File GSTR 3B Online: Step-by-Step Guide
To report the summary of sales and purchases, all taxpayers except those exempted have to file a monthly GSTR 3B. Once taxpayers have filed GSTR-1 and GSTR-2, they are required to file GSTR-3 B. Some of the details in this return are auto-populated from the GSTR 1 and 2, while the remaining details have to be filled out manually by the taxpayer. Here in the article, you will find a step-by-step guide to filling up the return online. Once the return is filed successfully, the taxpayer receives an alphanumeric Acknowledgment Reference Number sent to the registered mail ID or Mobile Number.
