Unfamiliarity with GST Returns

As with anything new, GST will also have its share of issues and problems in the initial stages. And it would be difficult for the taxpayers to file timely returns that are required to be filed under GST, for the simple reason of unfamiliarity with the procedures. There are many other reasons which make it difficult for taxpayers to file timely compliance like these returns ask for GSTIN Number[1] of the taxpayer, and many taxpayers are still not registered under the Act.

In order to ensure the smooth rollout of GST and after considering the recommendations of the key industry players, time limits for furnishing the Returns under GST are extended. After the Council meeting held on 18th June 2017, Arun Jaitley announced that return filing timelines under GST are to be relaxed and extended up to September.

Relaxations and Extension Granted

Decisions are taken in this council meeting state that a simplified tax return is to be filed in Form GSTR-3B, containing the summary of Inward and Outward supplies, for the period starting from July 2017 to March 2018.

This rule states that if the time limit for furnishing these details has been extended and circumstances so warrant, then return is to be filed in GSTR-3B in lieu of GSTR-3 (monthly return) as per the conditions as specified by the Commissioner.
