To make the process of Tax Return Filing easier and simpler, the GST Network has introduced an Offline mode Excel- based utility.
The taxpayers now can download the offline utility from the GSTN Portal under the download section, according to the GST Statement. After filing the data, the taxpayers need to upload the GSTR 3B Form from the GST Portal.

After the uploading formalities, then you have to preview the form and complete the other formalities like submit, offset the liability and file the GSTR-3B Return using the digital signature or an electronic verification code- the GSTN Says.
The CEO of the GSTN Mr. Prakash Kumar says that “This facility will provide an opportunity to every Taxpayer to verify the details of the GSTR-3B before filing and thus minimising the chances of the error.
