This blog post is updated with the GST Council’s decision to extend the return due dates

With the filing of GSTR-3B right around the corner on 20th August, 2017, businesses are in full swing gearing up to meet the deadline. Having said in our earlier blog ‘How to File Form GSTR-3B’, Form GSTR-3B is an interim return which needs to be filed for first 6 months: July to December, 2017 (Revised ). However, this does not mean that the businesses are not required to file GSTR-1, Form GSTR-2 and Form GSTR-3. It means, only the deadline to file GSTR-1, GSTR-2 and GSTR-3 are extended, and the businesses still need to file these return as per revised dates mentioned below:
