Shall I pay GST payment for unkonwnly cancelled invoice uploaded in GSTR-1

An invoice mistakenly reported in GSTR-1 should not be paid merely because it appears there. First check whether the underlying supply took place and whether tax was actually collected. If the invoice was cancelled before supply and no tax was due, correct the GSTR-1 error through the permitted amendment route, subject to the applicable time limit; keep the cancellation and reconciliation evidence. If the supply occurred, report and pay the correct GST, with applicable interest for any delay.

File GSTR-3B based on the correct tax liability, not simply by copying the GSTR-1 figure—but reconcile the difference and correct the outward-supply reporting. A mismatch may be flagged or lead to a departmental query; it does not automatically mean a notice or establish tax payable. The appropriate correction depends on the tax period, whether GSTR-3B is already filed, and whether the recipient’s ITC or tax payment was affected.

A clear invoice-to-return reconciliation helps identify and document this kind of reporting error before filing. Manual review across invoices and returns is difficult, while automation reduces repetitive work and keeps professional judgment in control.
