Union Budget 2026 has introduced a wide set of Indirect Tax proposals. While a significant portion of the Budget speech focuses on Customs tariff rationalisation, exemption review and trade facilitation measures, the GST / IGST legislative amendments proposed through the Finance Bill, 2026 are limited in number but important in impact primarily covering post-sale discounts, credit note linkage, refund rationalisation, interim appellate mechanism for advance rulings, and place of supply for intermediary services.
Accordingly, this article provides a clear, topic-wise summary of the GST / IGST law changes (Annexure B: B1 to B6), with section references, "before vs after" position, and key practical implications for taxpayers and professionals. Please note that most GST changes will take effect from a date to be notified (as GST implementation requires coordination with States and GST Council recommendations), except where a specific effective date is expressly stated (e.g., 01.04.2026 for the interim appellate arrangement).
The relevant Budget speech extract/annexure is attached/reproduced for ready reference. If you have any doubt or query on applicability, documentation, or impact on your transactions, feel free to contact me at the details mentioned at the end of the article.
