The CBIC issued the enabling notifications on 26 October, with a second, more sweeping set of legislative changes targeted for 1 April 2027.

The Central Board of Indirect Taxes and Customs (CBIC) has issued formal notifications dated 26 October 2026, bringing the first set of Goods and Services Tax (GST) reforms into effect from 1 November 2026. The changes — covering post-sale discounts, provisional refunds for inverted duty structures, and export refund thresholds — stem from decisions taken at the 57th GST Council meeting held on 8 October 2026 in New Delhi under the chairmanship of Union Finance and Corporate Affairs Minister Nirmala Sitharaman.
Key Changes Taking Effect on 1 November
Simplified rules and revised credit note provisions will make it easier for distributors and retailers to manage post-sale discounts from next month. Businesses facing an inverted duty structure — where GST on inputs is higher than GST on outputs — will now be eligible to claim 90 per cent provisional refunds upfront, subject to risk-based checks.
In a significant relief for small exporters, the earlier minimum threshold of ₹1,000 for tax-paid export refunds has been removed. This allows small courier and postal exporters to claim refunds without any floor limit, broadening the relief net considerably.
Clarity on Intermediary Services
The 'place of supply' rule for services rendered through intermediaries will shift to the location of the service recipient, rather than the intermediary's location. This change is expected to give Indian service exporters greater legal and tax certainty, addressing a long-standing ambiguity that had complicated compliance for cross-border service providers.
Automated Refund Processing and System Readiness
Automated sanctioning of refunds will begin after 1 November 2026, where applicable, according to a senior official. Crucially, this applies only to future refund claims and not to those already pending. A senior official noted that the rollout of reforms will be staged based on system upgrade timelines, with the focus on faster processing once infrastructure is ready.
Structural Reforms Targeted for April 2027
The next tranche of changes — which require formal legislative amendments to both Central and state GST laws — is targeted for 1 April 2027. These include modifications to arrest provisions, rationalisation of prosecution thresholds, changes to e-way bill rules, and a minimum threshold of ₹10,000 for issuing show-cause notices.
A senior official clarified that arrests already made will not be affected by the revised provisions. While the GST Council has decided to remove certain arrest clauses from the law, those changes will only apply prospectively from 1 April 2027. The department is reportedly examining interim guidance through administrative instructions, though no final decision has been taken as yet.
Together, the two-phase rollout reflects the Council's intent to reduce the overall compliance burden on taxpayers, improve the flow of input tax credit, and accelerate refund timelines across the GST ecosystem.
Point of View
The April 2027 deferral of arrest provision reforms and prosecution threshold changes risks leaving the most consequential taxpayer-protection measures hostage to legislative calendars. The gap between announcing reform intent and delivering legislative finality has historically been where GST momentum dissipates.

Frequently Asked Questions
What GST changes are coming into effect on 1 November 2026?
From 1 November 2026, businesses with an inverted duty structure can claim 90% provisional refunds upfront, simplified credit note rules for post-sale discounts take effect, and the ₹1,000 minimum threshold for tax-paid export refunds is removed. The CBIC issued the required notifications on 26 October 2026 to enable these changes.
What is an inverted duty structure under GST?
An inverted duty structure occurs when the GST rate on inputs is higher than the rate on finished outputs, causing input tax credit to accumulate as a refund liability rather than being offset. Sectors such as textiles and fertilisers are commonly affected, and the new 90% upfront provisional refund is specifically designed to ease their working capital pressure.
Who benefits from the removal of the ₹1,000 export refund threshold?
Small exporters using courier and postal channels benefit directly, as they were previously barred from claiming refunds on consignments below ₹1,000. With the floor removed, even low-value exports now qualify for tax-paid export refunds, making the system more equitable for micro and small businesses.
When will structural GST reforms like changes to arrest provisions take effect?
The next tranche of reforms — covering arrest provision changes, prosecution threshold rationalisation, e-way bill modifications, and a ₹10,000 minimum for show-cause notices — is targeted for 1 April 2027. These require formal amendments to both Central and state GST laws before they can be notified.
Will pending GST refund claims benefit from the new automated sanctioning system?
No. Automated sanctioning of refunds, once activated after 1 November 2026, will apply only to future refund claims. Refunds already pending in the system will be processed under the existing framework and are explicitly excluded from the new automated mechanism.
