I missed reporting a sale in my GSTR-1 for March 2025. If I now include this sale in my GSTR-3B working, there is an outward liability to pay.
Can I report the missed sale in GSTR-3B even though it was not included in GSTR-1? What are the implications, and will there be any interest or penalties for this adjustment?

Can you report missed sale in GSTR-3B even if not in GSTR-1? Technically, you should report all outward supplies (sales) in GSTR-1 first.
However, GSTR-3B is a summary return where tax liability is declared and paid. If you missed a sale in GSTR-1 but included it in GSTR-3B, your tax liability is at least accounted for in GSTR-3B, which is important.
Implications of reporting sale only in GSTR-3B and not in GSTR-1 Mismatch will occur: Your buyer wonโt see that invoice in their GSTR-2A, which may affect their Input Tax Credit (ITC).
Possible Notices: The GST department may notice the mismatch during reconciliation and ask for clarifications.
Interest and Penalty:
Since you are paying tax on the missed sale in GSTR-3B, you may have to pay interest for late payment of tax (usually 18% p.a. from due date of return).
Penalties may be levied if non-compliance persists or is deemed deliberate.
Best Practice / What to do now? Amend GSTR-1:
File a revised/amended GSTR-1 for March 2025 or subsequent month with the missed sale included. GSTR-1 amendments can be filed until the due date of September return of the following year.
Pay Interest:
Calculate and pay interest on the tax amount related to missed sale from the due date till payment date.
Inform Buyer:
Notify your buyer to consider this when claiming ITC.
