Unexplained CESS in GSTR1 Equal to Invoice Amount

[Ravi]

I filed GSTR-1 with a few B2B invoices. No Compensation Cess was entered, and the HSN summary also shows zero cess. But after filing, each invoice is showing the total invoice value in the Compensation Cess field. Because of this, GSTR-3B is auto-populating a huge and incorrect cess liability.

Has anyone seen this before or knows how to get it corrected?

AI Summary

Erroneous Compensation Cess auto-population in GSTR-1 may require invoice amendment or jurisdictional assistance when portal editing is unavailable.
Erroneous Compensation Cess auto-population may occur when GSTR-1 B2B invoices show total invoice value as cess despite no cess being reported, causing incorrect cess liability in GSTR-3B. Correction may be attempted through GSTR-1A, where available, by amending affected invoices to reduce cess to zero. If the facility is unavailable or closed, amendment in a subsequent return may be required, with assistance from the jurisdictional GST office where portal editing is disabled.
