Date Notified for Post-Sale Discounts where Prior Agreement No Longer Essential

Effective 1 November 2026, Section 153 of the Finance Act, 2026 amends Section 15(3)(b) of the CGST Act by removing the requirements for a prior agreement and linkage to specific invoices for post-sale discounts. Section 154 aligns Section 34(1) with this revised framework by expressly accommodating credit notes for qualifying post-supply discounts. The change expands commercial flexibility but does not dispense with the applicable statutory conditions, including the recipient's reversal of attributable ITC.
