From Oct 15, 2020, the Central Board of Indirect Taxes and Customs ( CBIC ) has explained that the generation of the E-Way Bill facility 
Get to know about GST E Way bill and its generating process through online and SMS in a simple manner. Also, we have attached original screenshots of official E way bill portal for better understanding to be obstructed for Taxpayers who missed to file GSTR-3B for 2 or higher Tax period.
A person is not allowed to take the facility of e-way bill generation if in case he misses filing the GSTR-3B returns for a continuous period of 2 or more months according to the act 138 E (b) of the CGST Rules, 2017.
The GST official in his latest meeting has concluded that this procurement will be made relevant to the taxpayers whose aggregate annual turnover, based on AATO, PAN is more than Rs 5 Crores.
Hence if the GSTIN is linked with the PAN and has missed filing the GSTR-3B return 
GST council decided GSTR 3B filing until March 2019 in the 27th meeting. We researched and published some interesting points that why Indian government extended GSTR 3B every time?. for two or more than that within the month of tax period of August 2020 then their EWB generation facility might get blocked at EWB portal. The announcement that after 15th October 2020 generation of EWB facility for GSTINs gets blocked on the portal.
To avail, the continuous GST E W Bill generation on the government portal one needs to file his pending GSTR-3B returns, said CBIC.
This is really unfair as under the current situation lot of corporations are not making payment in time either due to a shortage of staff or funds. Blocking e waybill will stop the movement of goods and affect growth. As the time limit for filing for all should be extended as per quarterly guidelines as this affects the working capital adversely.
CBIC should instead of becoming harsh on genuine tax payers come up with more relaxed guidelines.
