ABSTRACT
In the Union Budget 2026-27, the Finance Bill 2026 proposes a series of amendments to the Central Goods and Services Tax Act of 2017 and the Integrated Goods and Services Tax Act of 2017. These proposed changes seek to address practical issues that have emerged during GST implementation process over the past few years, especially with regard to post-sale discount value, refund bottlenecks, inverted duty structures, appellate gaps, and intermediary service taxation. This article analyses these proposals within the broader constitutional framework established by Articles 246A and 279A of the Indian Constitution, rather than just as technical statutory changes. In accordance with judicial precedents like VKC Footsteps India Pvt. Ltd. v. Union of India, and Union of India v. Mohit Minerals Pvt. Ltd., this study states that these proposals reflect a continuing evolution of the GST regime toward greater administrative efficiency, cooperative federalism, and commercial realism.
INTRODUCTION
The Goods and Services Tax is a constitutional innovation instead of just a fiscal reform. Article 246A, which gives Parliament and State Legislatures the simultaneous legislative power to implement GST laws, was enacted by the Constitution (One Hundred and First Amendment) Act, 2016. The GST Council was further established by Article 279A as a federal coordination structure where the Union and the States collaborate to discuss tax rates, exemptions, and modifications to policy.
In Union of India v. Mohit Minerals Pvt. Ltd., the Hon’ble Supreme Court made it clear that although the GST Council’s suggestions have a lot of persuasive power, neither Parliament nor state legislatures are required to follow them. This finding supported the notion that cooperative federalism, not strict centralization, is the foundation of GST. Therefore, it is necessary to view the adjustments included in the Union Budget 2026–27 as legislative exercises under Article 246A, which are eventually enacted through parliamentary sovereignty but are informed by discussions held by the GST Council.
The Union Budget 2026-27 adjustments do not represent significant fundamental changes when seen through this constitutional lens. Rather, they are little adjustments meant to address implementation issues that have surfaced over time. They demonstrate an understanding that a new tax system needs to remain constitutionally based while adjusting to real world circumstances.
POST-SALE DISCOUNT VALUATION REFORMS
One of the most popular suggestions in the Union Budget 2026-27 is the change to Section 15 of the CGST Act regarding post-sale discounts. Businesses could only deduct post-sale reductions from the taxable value under the previous framework if they were clearly linked to invoices and agreed upon prior to or at the time of supply. This, in principle, guaranteed clarity. But in reality, it led to preventable rigidity.
Dynamic pricing models are frequently used in contemporary business transactions. Often, incentive based discounts are established following an evaluation of market conditions, turnover accomplishments, or performance goals. Simply because the discount was not properly recorded at the time of supply, businesses became embroiled in valuation disputes. Despite its good intentions, the law did not take business realities into account.
The proposed change in the union budget permits the exclusion of post-sale discounts without requiring a pre-existing agreement, as long as a credit note is supplied and the recipient reverses the proportionate input tax credit. This change is indicative of a more pragmatic view of business. While protecting revenue through ITC reversal, it places more emphasis on economic substance than administrative details. The revision is in line with the generally held judicial view that taxes ought to be applied to genuine consideration rather than fictitious or exaggerated invoice values.
CREDIT NOTE CLARIFICATIONS
The change to Section 34 of the CGST Act pertaining to credit notes is closely related to value reform. Previously, there was no clear statutory connection between Sections 15 and 34, even if credit notes were issued for post-supply adjustments. Departmental protests and disagreements over interpretation were made possible by this ambiguity.
Judicial precedents have consistently emphasised that tax authorities must operate strictly within the statutory framework. Clear procedures are a defence against capricious behaviour, not just a formality. The legal basis for credit note modifications is strengthened by the proposed harmonization of Section 34 with the updated valuation provisions.
The amendment increases taxpayer confidence by clearly acknowledging credit notes as legitimate tools for post-supply value reduction. Businesses are reassured that valid commercial adjustments will not be viewed suspiciously if they are accompanied by the appropriate paperwork and ITC reversals.
REFUNDS UNDER INVERTED DUTY STRUCTURE
The Hon’ble Supreme Court in VKC Footsteps India Pvt. Ltd. v. Union of India upheld the legislature’s power to structure refund formulas but also acknowledged that refund provisions are matters of economic policy. Under the GST, refund delays have long been a pressing issue. While exporters were entitled to 90 percent provisional refunds in zero-rated supply cases, industries facing inverted duty structures were excluded from similar relief, meaning that manufacturers paying higher tax on inputs than on outputs frequently experienced prolonged working capital blockages. This is why the extension of the provisional refund mechanism to inverted duty cases is a meaningful reform. As recognised in VKC Footsteps, refund entitlements under GST remain matters of legislative policy.
The amendment achieves a balance between economic facilitation and fiscal responsibility by increasing provisional reimbursements while maintaining verification protections. It increases cash flow efficiency without changing the tax base; thus, revenue interests are not compromised.
RELIEF FOR SMALL EXPORTERS
The previous regulation that denied refund requests for less than ₹1,000 seemed insignificant financially, yet it had disproportionately negative effects on micro and small exporters. Even tiny refunds might add up to significant working capital for a small business owner sending sparse loads.
This threshold for export related refunds was removed in order to show consideration for MSMEs. It affirms that exports are zero rated under the IGST framework and makes sure that statutory rights aren’t withheld for simply procedural reasons. The change bolsters India’s commitment to inclusion and export promotion from a policy perspective.
APPELLATE MECHANISM REFORM
The National Appellate Authority’s non-constitution caused ambiguity in cases involving advance rulings. In the absence of a clear appellate venue, taxpayers had to deal with contradictory decisions. Procedural continuity is restored by the temporary solution that gives an existing tribunal the authority to hear such appeals.
While the right to appeal is statutory in nature, prolonged absence of an effective appellate forum may raise concerns of procedural fairness. Tax laws may specify particular forums, but if these are not established right away, public trust in the system is weakened. Until a permanent authority is established, the Union Budget 2026 amendment safeguards taxpayers’ rights and demonstrates administrative pragmatism.
INTERMEDIARY SERVICES AND PLACE OF SUPPLY
The IGST Act’s removal of Section 13(8)(b) is arguably the most fundamentally important change. The previous clause taxed intermediary services even when they were used overseas since it considered the supplier’s location to be the place of supply. This provision attracted constitutional debate regarding its alignment with the destination based structure of GST.
The constitutional difficulty of taxing services that were essentially exports was brought to light by judicial discussions, such as those held before the Hon’ble Bombay High Court. If implemented, the proposed change may align intermediary services more closely with the general place of supply rule based on the recipient’s location. It makes Indian service companies more competitive and harmonizes domestic legislation with international VAT norms.
ROLE OF THE GST COUNCIL
The amendments also demonstrate how Article 279A’s cooperative federalism works. The suggestions made by the GST Council are convincing but not legally binding, as was made evident in Mohit Minerals. However, the consultative character of the GST reforms highlights the system’s collaborative spirit.
The ideas for Budget 2026 seem to be the result of substantial stakeholder participation and council discussions. They represent negotiated changes meant to increase systemic efficiency rather than arbitrary fiscal decisions.
CONCLUSION
The planned GST revisions in the Union Budget 2026–27 are not radical changes but rather deliberate improvements. The government has resolved practical issues with the GST regime by restoring destination-based taxation for intermediary services, strengthening the legitimacy of credit notes, extending provisional refunds, assisting small exporters, maintaining appellate remedies, and liberalizing valuation rules.
The shift from structural establishment to functional optimization is reflected in these measures. Legal precedents that have emphasized constitutional balance, statutory clarity, and procedural justice include Mohit Minerals and VKC Footsteps. These concepts are in line with the proposed modifications.
The reforms might reduce litigation, increase liquidity, and solidify India’s indirect tax structure if they are carried out with administrative effectiveness and digital readiness. In the end, they indicate that the GST is changing not just as a tax structure, but also as a collaborative constitutional experiment that is adjusting to the reality of the economy.
