It is not possible to revise GSTR-3B once it is filed.
However, the Government has allowed 'Reset GSTR 3B' through which the status of 'Submitted' will be changed to 'Yet to be Filed', and all the details filled in the return will be available for editing. All the entries posted in the Electronic Liability Register will be deleted, and the ITC of this return integrated with the Electronic Credit Ledger will be reversed. This option can be availed only once.
Let’s see how it is to be done:
Step 1: Log in to the GST portal and go to the RETURN DASHBOARD
Step 2: Select the year and the month for which you want to reset GSTR-3B
Step 3: Click on Prepare Online
Step 4: Since you have already submitted the return, the option to 'Reset GSTR 3B' will be activated
Step 5: Click on ‘Reset GSTR 3B’
Step 6: Click on ‘Yes’ and ‘OK
Now that you have reset the return and status changed to ‘Yet to be filed’ make changes to return and submit again. Note: Details provided in the return will not be changed only status changes.
After reviewing, if you find errors or need to make changes, you can go to the tiles and edit the figures.
Invoice-level details need not be provided in the GSTR-3B. Thus, this leaves scope for errors while computing output tax liability and Input tax credit (ITC), leading to incorrect tax paid. Any incorrect computation of tax liability would add to the taxpayer's additional compliance burden.
There was no option for making changes or corrections in the GSTR-3B once you clicked the 'SUBMIT' button. You had to proceed to file using the DSC or EVC directly. The taxpayers were, therefore, inconvenienced if they committed any errors while submitting GSTR details in the values or tax figures or omitted to furnish some information in return.
The Government has now provided a breather to taxpayers by introducing the 'RESET GSTR-3B' feature, which allows them to make a one-time correction in the tax figures posted to the Electronic Liability Ledger before making payment of tax in GSTR-3B. Therefore, these options give the taxpayer a chance to be cautioned of any errors apparent on record and make corrections.
Note: Once the taxpayer submits the return, the value of Outward supplies cannot be changed. The value of outward supplies becomes locked, and any corrections or changes intended to be made must be made while filing the GSTR-1.
