Finally Great News for all GST Taxpayers.
As per GST Law 20th October was the last date to add/modify/correct/delete any details of outward supplies or inward supplies pertaining to previous financial year. So that means any rectification in already filed return of July 2017 to March 2018 is possible on or before 31.10.2018 (being due date for filing GSTR 1 as per relaxation given by Govt).
But being first year of GST many taxpayer filed return with many mistake & many a times instead of having GSTN of parties, invoice was filed in B2C or with wrong GSTN. But the same mistake was noticed by purchaser after 31.10.2018 & I heard that purchaser got an opportunity to delay payment or stop payment for invoice with a reason that bills was not reflected in B2B so payment will be not released unless the same will be modified or corrected.
This was genuine problem faced by all dealers until Govt come up with great news
In terms of Order No.02/2018-Central Tax dated 31st December 2018, rectification of error / omission in respect of Form GSTR-1 for the FY 2017-18 would be allowed till the due date of furnishing of Form GSTR-1 for the month of March 2019 i.e. April 11, 2019.
Government has already started the new functionality on GST Portal. So now January 2019 GSTR 1 allows amendment in invoice pertaining to financial year 2017-18.
But please note that last date to amend bills is 11.04.2019 so take this opportunity & rectify all your GSTR1 related mistakes.
