New GST rules from Nov 1: Key changes for taxpayers, MSMEs, businesses

Goods and Services Tax (GST) framework is set for a fresh round of reforms from Sunday (November 1), with changes to post-supply discounts, refund processing and export-related provisions expected to ease compliance and improve working capital for businesses. The measures follow the 57th GST Council meeting, which focused on administrative simplification, taxpayer facilitation and reducing disputes.

The government, through Notification No. 03/2026–Central Tax dated October 26, 2026, has appointed November 1 as the effective date for Sections 153 to 155 of the Finance Act, 2026. Other recommendations, including expanded refund eligibility and changes to input tax credit (ITC), will require the relevant legislative and procedural amendments before implementation.

Post-sale discounts

One of the key changes concerns post-supply discounts. The amendment to Section 15(3)(b) of the Central Goods and Services Tax (CGST) Act removes the requirement for discounts to be established through an agreement entered into before or at the time of supply. Eligible discounts can now be excluded from the taxable value where the supplier issues a credit note and the recipient reverses the attributable ITC in accordance with Section 34.

Section 34 has also been amended to align the credit-note framework with the revised valuation provisions.

"The requirement to establish such discounts through an agreement has been removed. Businesses can now issue GST credit notes for eligible post-sale discounts, subject to the recipient reversing the corresponding ITC. The change will enable businesses to offer discounts to dealers to drive sales while also availing the benefits associated with credit notes," said Rahul Shekhar, Partner–Indirect Tax at Nangia Global.

He added that the earlier framework could impose an additional cost on businesses where a clearly documented agreement was absent. FMCG, pharmaceutical, retail and consumer-durables companies, which commonly use dealer incentives and volume-based discounts, are expected to benefit.

Faster refunds

The GST Council has also recommended a more automated, risk-based refund mechanism. The proposed first phase includes automatic refunds of excess electronic cash ledger balances, reducing the acknowledgement or deficiency-memo timeline from 15 days to 10 days, and provisional sanction of 90 per cent of eligible refund claims relating to zero-rated supplies and inverted duty structure, subject to system-based risk assessment.

The Council has separately recommended expanding inverted duty structure refund eligibility to include input-service ITC availed on or after November 1, 2026. Eligible capital-goods ITC is proposed to be included in refunds for zero-rated supplies and inverted duty structure from April 1, 2027, with the refund spread over 60 months.

"The reforms taking effect from 1 November 2026 mark an important step towards simplifying GST processes, enhancing predictability and aligning the tax framework more closely with commercial realities," said Saurabh Agarwal, Tax Partner at EY India.

He said businesses should revisit discount and credit-note policies, strengthen ITC and refund tracking, and review pending disputes to prepare for the transition.

Greater certainty

Agarwal said the latest clarifications on registration address practical issues involving co-working spaces, consent-based premises, ATMs, telecom towers and state-specific information requirements. Clearer documentation standards could make registration more predictable and reduce inconsistent interpretations.

He also highlighted the importance of structured adjudication, including clearly articulated allegations, supporting evidence, consideration of taxpayers' submissions and reasoned orders. Such safeguards could improve consistency and reduce avoidable litigation.

On the Input Service Distributor (ISD) mechanism, he said greater clarity on the timing of credit distribution addresses an important implementation issue. For exporters, recognition of set-off as a valid settlement mechanism under FEMA could also provide relief where export receivables are adjusted against import payables in accordance with applicable RBI directions.

MSMEs, e-commerce await further changes

The wider reform agenda could benefit smaller businesses, exporters, manufacturers and taxpayers facing prolonged disputes. Proposed measures include simplified registration for small e-commerce sellers, an optional annual return framework for eligible consumer-facing businesses with turnover up to Rs 5 crore, rationalisation of blocked ITC and changes to enforcement provisions.

For small sellers, the possibility of using an e-commerce operator's warehouse as a principal place of business in another state could reduce the need to establish separate premises merely to expand nationally.

"The 57th GST Council's administrative reforms deserve attention now," said Ikesh Nagpal, Lead, Indirect Taxation, AKM Global, highlighting automated refunds, risk-based provisional sanctions and shorter acknowledgement timelines as measures that could improve liquidity, particularly for exporters and MSMEs.

Nagpal said proposed changes to ITC restrictions, prosecution thresholds, enforcement safeguards and goods movement could also reduce compliance costs and operational uncertainty. However, businesses should distinguish between measures already notified and recommendations awaiting legal changes.

Overall, the reforms signal a shift towards a more predictable, business-oriented GST regime. Their ultimate impact will depend on timely implementation, clear guidance and consistent application across tax administrations.
