GSTR-3B return is due on the 20th of August and 20th of September 2017. From October 2017, the taxpayers would be required to file GSTR-1, GSTR-2 and GSTR-3, as per normal schedule. Hence, GSTR-3B is a temporary return that must be filed monthly until October, 2017.
The Government has mentioned that during the GST transition period, leniency would be shown to taxpayers to familiarize themselves with the GST provisions. Hence, no penalty has so far been announced for not filing GSTR-3B return. However, it is expected that taxpayers who fail to file GSTR-3B returns would be ineligible to being filing GSTR-1, GSTR-2 and GSTR-3 returns from the month of October. Failure to file GSRT-1, GSTR-2 and GSTR-3 returns will attract penalty of ₹ 100 per day.
