GSTR 1A – A Comprehensive Guide to Details, Return Filing and Format

Avatar photo

In 2024, the reintroduction of the GSTR-1A form has given taxpayers an essential tool for ensuring accuracy in their GST returns. This form allows businesses to amend details of their outward supplies that were initially submitted in GSTR-1. It serves as a practical bridge for correcting any discrepancies or omissions discovered after filing GSTR-1 but before submitting the final GSTR-3B for that tax period. 

GSTR-1A simplifies the process of updating sales records, reducing the risk of compliance issues that could arise from inaccuracies. If, for example, an error or a missing entry is found in the GSTR-1 filing, GSTR-1A provides a way to correct it. By recording these changes in GSTR-1A, taxpayers can ensure their records accurately reflect all sales, maintaining consistency and clarity in their GST filings. 

This streamlined approach helps to align monthly filings more effectively, as it minimizes discrepancies between GSTR-1 and GSTR-3B, ensuring a smoother, more reliable GST filing process. 

Why Do You Need GSTR-1A? 

The CBIC (Central Board of Indirect Taxes and Customs), through one of its notifications in 2024, announced a proviso to Rule 59(1) to reintroduce the GSTR-1A form. This form enabled taxpayers to update the changes to their sales invoices submitted in the GSTR-1 form.  

The time for filing GSTR-1A is after filing your GSTR-1 form but before filing your GSTR-3B form. 

Timelines to File GSTR-1A 

GSTR-1A can be filed after the GSTR-1 is submitted but must be done before the GSTR-3B filing for the same tax period. This time window allows businesses to correct any errors or omissions in the outward supplies reported in GSTR-1. It's important to file GSTR-1A on time to ensure your GSTR-3B is accurate and in compliance with GST rules. 

  • Monthly Filers

    Can file GSTR-1A after the due date of GSTR-1 (11th of the following month) and before filing GSTR-3B. 
  • Quarterly Filers

    Can file GSTR-1A after the due date for quarterly GSTR-1 (13th of the month following the quarter) and before filing GSTR-3B for the same quarter.

How Does GSTR-1A Work? 

GSTR-1 is where sellers report all their sales records for a given period, with the details automatically populating the buyer’s GSTR-2B for input tax credit. If any corrections or updates are needed after GSTR-1 is filed, the seller submits those through GSTR-1A. These changes then flow into the buyer’s GSTR-2B and, ultimately, their GSTR-3B. 

The distinction is straightforward: GSTR-1 captures all sales data, while GSTR-1A handles any amendments to that data within the same period. 

Example 

  • Mr. X buys 100 chocolates worth Rs.500 from Mr. Y 
  • Mr. Y mistakenly furnishes a wrong sales transaction of Rs.50 while filing his GSTR-1. 
  • The same incorrect number flows automatically in the buyer’s (Mr. X’s) GSTR-2B. 
  • Now, Mr. Y realises the errors and wants to amend his sales value. So, he uses the GSTR-1A form to update his sales value as Rs.500. 
  • Now, the buyer’s GSTR-2B will automatically reflect the change. Eventually, his tax liability form of GSTR-3B will also be automatically corrected.
