Valid GST-adjusting credit notes may alter turnover, but only where their statutory basis, invoice linkage, documentary support and applicable time limit are established. Commercial credit notes that merely reduce amounts payable do not automatically reduce GST or turnover for the formula. If a deduction is inadmissible, the permissible refund must be recalculated and compared with the amount claimed or sanctioned; an error alone does not establish an excess refund. en-us Thu, 15 Oct 2026 05:45:12 +0530 Thu, 15 Oct 2026 05:45:13 +0530 TaxTMI RSS Generator https://www.taxtmi.com/article/detailed?id=17577 Rule 89(4) export-refund calculation must use corrected zero-rated turnover, Net ITC and adjusted total turnover.
