GSTR 3B Return

The tax authorities have introduced a simple return form called as GSTR 3B to ease the burden on taxpayers. This has to be used for the months of July to December. Every registered taxpayer has to file a separate GSTR 3B for each GSTIN they have.

This is more like a self-declaration return and the taxpayer is not required to provide invoice level information in this form. Only total values for each field have to be provided.
