Three changes to India's Goods and Services Tax law came into force on 1 November 2026. Notification No. 03/2026, dated 26 October, brought into effect provisions of the Finance Act, 2026 that were announced in the Union Budget for 2026-27. The first lets a supplier give a discount after the sale and issue a credit note for it, as long as the buyer reverses the matching input tax credit. The second extends a provisional refund of 90 percent within seven days to eligible claims under an inverted duty structure. The third removes the Rs 1,000 minimum limit for refund claims on goods exported with payment of tax. The notification also fixes 1 November 2026 as the day Sections 153 to 155 of the CGST Act come into force.
The argument that the changes help business starts with cash flow. Until now, a discount could be left out of the taxable value only if it had been agreed at or before the time of supply, a condition that did not fit later incentives. Rahul Shekhar of Nangia Global told BusinessToday that the change benefits FMCG, pharmaceuticals, retail and consumer durables, where dealer incentives and volume-based discounts are common. The 90 percent provisional refund within seven days, which earlier applied only to zero-rated supplies, now reaches businesses whose input taxes are higher than their output taxes, and the finance ministry's changes are expected to help unlock working capital that was stuck waiting for refund orders. Removing the Rs 1,000 floor helps small exporters, whose individual claims could previously fall below the limit and go unsanctioned.
The argument for caution is that the relief is narrower than the headlines suggest. A provisional refund covers 90 percent, not the full amount, and the remaining 10 percent still waits for final sanction. The Rs 1,000 limit is removed only for tax paid on goods exported, and other categories of refund claims keep it. The discount rule comes with a compliance condition, because the supplier must issue a credit note and the recipient must reverse the corresponding credit, so both sides of every transaction have to match their records. Some commentators also report that other proposals, such as automated refunds and easier registration for e-commerce sellers, are still pending, and advisers disagree on whether credit on input services counts toward inverted duty refunds, so businesses may need to wait for clearer guidance.
The provisions were passed as part of the Finance Act, 2026 and were approved by the GST Council at a meeting last year, so businesses have had notice that they were coming. The changes matter because refund delays and paperwork are among the most common complaints about the tax. Faster payment for inverted duty claims and a clearer treatment of discounts affect manufacturers, distributors and exporters across the country, and money returned sooner is money a firm can spend on stock, wages and expansion. At the same time, the credit note rule puts more weight on accurate reporting, so companies that sell through dealer networks will have to keep tighter records of every discount they give.
The 1 November changes are a practical step rather than a rate cut. Whether they ease the pressure on business will depend on how quickly refunds are actually paid and how clearly the remaining rules are explained.
