No CommentsCBIC GST Changes 2026: New GST Rules Effective from 1 November
The Central Board of Indirect Taxes and Customs (CBIC) has notified important changes to the Goods and Services Tax (GST) framework under the Finance Act, 2026. These amendments came into force on 1 November 2026, following Notification No. 03/2026–Central Tax dated 26 October 2026.
The changes amend Sections 15, 34 and 54 of the Central Goods and Services Tax (CGST) Act, 2017. They mainly concern the treatment of post-supply discounts, credit notes, provisional refunds under the inverted duty structure, and the minimum refund threshold for certain export claims.
CBIC GST Changes 2026: Post-Supply Discounts, Refunds and Export Benefits
The Central Government issued Notification No. 03/2026–Central Tax on 26 October 2026, appointing 1 November 2026 as the commencement date for Sections 153, 154 and 155 of the Finance Act, 2026.
These provisions amend three important sections of the CGST Act, 2017:
Section 15 – Value of taxable supply
Section 34 – Credit and debit notes
Section 54 – Refund of tax
1. Post-Supply Discounts: Removal of Prior Agreement and Invoice-Linkage Conditions
One of the major GST changes concerns discounts offered by suppliers after completing a sale.
Earlier, under Section 15(3)(b) of the CGST Act, a post-supply discount could be excluded from the taxable value only when:
The discount was established through an agreement entered into before or at the time of supply.
It was specifically linked to relevant invoices.
The recipient reversed the Input Tax Credit (ITC) attributable to the discount.
What has changed from 1 November 2026?
The amended Section 15(3)(b) removes the requirements for a prior agreement and specific invoice-wise linkage.
A post-supply discount can now be excluded from the value of supply if:
The supplier issues a credit note for the discount.
The recipient reverses the ITC attributable to that discount.
The credit note and ITC reversal comply with Section 34 and applicable GST provisions.
Example:
Suppose a manufacturer offers a year-end discount of ₹50,000 to a distributor after completing the supply.
Under the amended provisions, the manufacturer may issue a GST credit note for the qualifying discount without needing a prior agreement or strict invoice-wise linkage. However, the distributor must reverse the corresponding ITC attributable to the discount.
Why is this important?
Greater flexibility in offering promotional and year-end discounts.
Simplified GST documentation requirements.
Better support for trade schemes and business incentives.
Reduced compliance burden for suppliers and recipients.
2. Provisional GST Refunds for Inverted Duty Structure
Another important change relates to refunds arising from an Inverted Duty Structure (IDS).
An inverted duty structure occurs when the GST rate on inputs is higher than the GST rate on outward supplies. This can result in accumulated unutilised Input Tax Credit (ITC), blocking business working capital.
What has changed?
The amendment to Section 54(6) extends the statutory provisional refund mechanism to eligible refunds of unutilised ITC arising from an inverted duty structure under Section 54(3).
This allows eligible taxpayers to receive up to 90% of the claimed refund provisionally, subject to applicable conditions and risk-based assessment.
How does the provisional refund mechanism work?
The taxpayer files a refund application.
The application undergoes acknowledgement and eligibility checks.
Eligible low-risk claims can receive 90% of the claimed amount provisionally through system-based processing.
The remaining claim undergoes scrutiny and final processing by the proper officer.
Important timeline clarification: The PIB’s refund FAQ states that the provisional refund order in Form GST RFD-04 is proposed to be issued within three working days from acknowledgement under the automated process. This is not an unconditional seven-day payment guarantee for every refund applicant. The facility is subject to risk classification, exclusions and statutory restrictions.
Benefits for businesses:
Improved working capital availability.
Reduced financial pressure caused by accumulated ITC.
Faster processing of eligible refund claims.
Improved ease of doing business.
3. Removal of ₹1,000 Minimum Refund Limit for Certain Export Claims
The Finance Act, 2026 also amends Section 54(14) of the CGST Act.
Earlier, refund claims below ₹1,000 were generally restricted under this provision.
What has changed from 1 November 2026?
The ₹1,000 minimum refund restriction no longer applies to claims relating to goods exported out of India with payment of tax.
This is particularly beneficial for small exporters and businesses making low-value export consignments through courier and postal channels.
Important: This exemption from the minimum threshold is limited to the specified category of goods exported with payment of tax. The ₹1,000 restriction continues to apply to other refund categories covered by Section 54(14).
