In order to assist taxpayers in filing their returns and minimizing human errors, GSTN has continuously improving the GST return filing process and in this endeavor the GST Portal now provides a pre-filled GSTR-3B form, where
1. The tax liability is auto-populated from the declared supplies in GSTR-1/ GSTR-1A/ IFF by the supplier, and
2. The Input Tax Credit (ITC) is auto-populated from GSTR-2B.
A detailed system generated pdf of the auto populated GSTR-3B is also provided to all the taxpayers.
Now, the question arises that what if there is any clerical mistake in GSTR-1 or taxpayer missed to report any invoice or reported any incorrect details in GSTR-1…?
In such situation, no need to worry. Now, taxpayers also have a facility to amend their incorrectly declared outward supplies in GSTR-1/IFF through GSTR-1A. Additionally, to manage inward supplies and ensure accurate ITC claims in GSTR-3B, taxpayers have the option to take informed actions of accept/reject/pending on inward supplies via the Invoice Management System (IMS) which is now available to the taxpayers.
Lets discuss all about GSTR-1A.
What is Form GSTR-1A- In simple term, we can say that GSTR-1A is a return which provides you a facility to revise/amend/correct errors in the records furnished in GSTR-1 of the period in the same month before filing GSTR-3B. A taxpayer who wants to amend any supply details furnished in GSTR 1 or want to add any supply details of same tax period, the same can be done through GSTR 1A in the same month.
When this facility (i.e. GSTR-1A) available- GSTR-1A will be available from later of (date of filing of GSTR-1 or due date of filing GSTR-1) and will be available till filing of form GSTR-3B.
Due date of filing GSTR-1A- this facility is available till the actual date of filing of form GSTR-3B. In simple words, there is no any due date for GSTR-1A, it can be filled till the filing of GSTR-3B of the same tax period.
It may be noted that tentatively from January 2025 tax period, the GST Portal is going to restrict making changes in auto-populated liability in pre-filled GSTR-3B from GSTR-1/1A/IFF to further enhance accuracy in return filing.
However, locking of auto-populated ITC in GSTR-3B, after the roll out of IMS, will be implemented from a later date.
Insightful sir.
