What are the six GST amendments in Finance Act 2026?
| Provision | Change | Status at 29 July 2026 |
|---|---|---|
| CGST 15(3) | Removes prior-agreement linkage for post-sale discount; links to section 34/recipient ITC reversal | Enacted; commencement notification required |
| CGST 34 | Adds section 15 linkage for credit notes | Enacted; commencement notification required |
| CGST 54(6) | Extends provisional refund to inverted-duty structure | Enacted; commencement notification required |
| CGST 54(14) | Removes minimum refund threshold for goods exported with tax | Enacted; commencement notification required |
| CGST 101A | Allows existing Authority/Tribunal to be empowered for national advance-ruling appeals | Effective 1 April 2026; forum notification still needed |
| IGST 13(8)(b) | Omits special intermediary place-of-supply rule | Effective 30 March 2026 |
Why does commencement matter?
Section 1 of the Finance Act groups provisions by date. The fact that Parliament enacted an amendment does not authorise a taxpayer to use text whose commencement is expressly deferred. Track “Bill,” “enacted,” “commenced” and “rules/portal enabled” separately.
How will the discount change work when commenced?
The amendment removes the requirement that a post-supply discount be established by an agreement entered into at or before supply and linked to invoices. It instead ties value reduction to a section 34 credit note and reversal of attributable ITC by the recipient. Until commencement, apply the existing section 15(3) conditions.
What changes for refunds when commenced?
Section 54(6) will support provisional refund for inverted-duty claims, implementing a major Council policy direction. Section 54(14) will remove the minimum refund threshold for goods exported with payment of tax. Rules, forms and operational instructions must be aligned before treating either change as portal-ready.
What is the intermediary-services effect?
Omitting section 13(8)(b) means the special supplier-location rule no longer applies to intermediary services for post-change periods. The general section 13(2) recipient-location rule can make qualifying services exports, but the service must still satisfy the intermediary definition analysis and every section 2(6) export condition. Do not relabel an ordinary principal-to-principal service without facts.
What does the advance-ruling amendment actually do?
It permits the Government to empower an existing Authority, including a Tribunal, pending constitution of the National Appellate Authority. The statutory power is effective, but taxpayers need the actual empowering notification and procedural route before filing.
What should businesses change now?
Create a commencement register. Do not alter discount clauses or refund assumptions for deferred provisions yet. For intermediary services from 30 March 2026, re-evaluate contracts, invoicing, place of supply, foreign-exchange realisation and LUT/refund process. Monitor CBIC/Gazette notifications for sections 137–139.

Frequently asked questions
Is Finance Act 2026 enacted?
Yes. The updated India Code CGST Act identifies Finance Act 2026 as Act 4 of 2026. Each amendment still needs its own commencement analysis.
Are the new post-sale discount rules operational?
Not merely because the Act was enacted. Sections 137–139 are tied to a date appointed by notification; verify a commencement notification before applying them.
What changes for inverted-duty refunds?
The Act amends section 54(6) to extend provisional refund to inverted-duty claims, but that amendment belongs to the separately notified group.
What changes for low-value export-with-tax refunds?
The section 54(14) threshold restriction is removed for goods exported with payment of tax under the enacted amendment, subject to its commencement notification.
When did the advance-ruling amendment start?
The enabling amendment allowing an existing Authority, including a Tribunal, to be empowered as the National Appellate Authority applies from 1 April 2026. An actual forum still depends on the required notification.
When did the intermediary place-of-supply change start?
The omission of IGST section 13(8)(b) took effect on 30 March 2026, so section 13(2)’s default framework applies to post-change intermediary services, subject to all export conditions.
