Karnataka HC Allows Correction of GSTR-1 Error (B2C Shown as B2B) – Relief for Businesses

For many businesses, outward supply reporting in GSTR-1 is handled by teams or software, and one wrong click can convert a B2C sale into a B2B invoice on the GST portal. This is precisely the issue that came up before the Karnataka High Court in case citation TS-1031-HC(KAR)-2025-GST, where the Court permitted correction of such a mistake and granted relief to the taxpayer.​

In this case, the assessee had reported certain B2C supplies as B2B in Form GSTR-1, creating mismatches and unnecessary complications in the return data. The department refused to allow rectification beyond statutory timelines, taking a rigid view that once GSTR-1 was filed, no correction could be made for what it labelled as “clerical errors”.​

The Karnataka High Court took a more practical and justice-oriented approach. It recognised that mis-tagging B2C as B2B was a reporting error in the return and not a case of tax evasion, especially when tax had already been paid correctly. The Court held that such errors can and should be rectified, and directed the authorities to permit correction of GSTR-1 so that the return reflects the true nature of supplies, subject to necessary verification.​

This judgment is consistent with the broader jurisprudence where High Courts have allowed rectification of GSTR-1 where entries were mistakenly shown in B2C instead of B2B (and vice versa), to avoid unjust denial of ITC or unfair demands. With GSTN now enforcing stricter separation of B2B and B2C reporting and introducing new validations in GSTR-1, the risk of such classification errors has only increased for businesses in Delhi NCR and across India.​

What should businesses in Delhi NCR do in such cases?

• First, identify and document the error clearly, with invoice-wise mapping of what was reported and what should have been reported.​
• Second, demonstrate that the correct tax has been paid through GSTR-3B and ledgers, so that there is no revenue loss to the department.​
• Third, file a detailed representation with the jurisdictional officer citing TS-1031-HC(KAR)-2025-GST and similar rulings permitting rectification of GSTR-1 in cases of inadvertent mis-reporting.​

For taxpayers across Noida, Delhi and the wider NCR region, this case offers a strong legal basis to seek correction rather than silently bearing the cost of portal or human errors. Proper documentation and a focused legal strategy can convert an embarrassing mistake into a manageable rectification exercise, instead of a prolonged dispute.
