The Hidden Business Risks in GST Fourth Amendment Rules 2025

The Cost of Scaling Up
The Hidden Business Risks in Notification No. 18/2025
The Constitutional Infirmities of the GST Fourth Amendment Rules, 2025: A Critical Evaluation

The introduction of Rules 9A and 14A via Notification No. 18/2025–Central Tax marks a paradigm shift in the onboarding of taxpayers under the Central Goods and Services Tax (CGST) Rules, 2017. While the stated administrative objective is to accelerate registrations and enhance the “ease of doing business,” a deeper constitutional scrutiny reveals severe structural vulnerabilities. By substituting automated risk-profiling for manual checks and imposing draconian exit conditionalities, the executive branch has introduced mechanisms that actively penalise merchant growth, deny true tax reporting, and spark serious issues regarding fundamental rights, delegated legislation, and commercial survival.

I. Article 14 and Manifest Arbitrariness: The Anomaly of the Rigid Threshold

Article 14 of the Constitution of India forbids class legislation but permits reasonable classification. For a classification to pass constitutional muster, it must satisfy the twin-test established in State of West Bengal v. Anwar Ali Sarkar (1952):

• The classification must be founded on an intelligible differentia which distinguishes persons or things that are grouped together from others left out of the group.
• The differentia must have a rational nexus to the object sought to be achieved by the statute.

The Trap of Rule 14A(12): Forced Misreporting of Liabilities

While differentiating taxpayers based on their tax liability satisfies the test of intelligible differentia, the operational execution of Rule 14A(12) results in manifest arbitrariness. Under this rule, a taxpayer is legally prevented from reporting their actual output tax liability on the portal the moment they breach the ₹2,50,000 limit.

In Shayara Bano v. Union of India (2017), the Supreme Court held that an executive action is unconstitutional if it is “manifestly arbitrary”—meaning it is done irrationally or without adequate determining principles. Rule 14A(12) forces an absolute block on retroactive amendments. In a digital, real-time tax environment, a law that actively prevents an honest citizen from accurately declaring and paying their actual tax liability to the state treasury is the very definition of manifest arbitrariness.

II. The Practical Compliance Nightmare: A Chronological Case Study

To understand how this rule penalises business growth and acts as a constructive ban on trade, we must examine a real-world compliance timeline. The law stipulates that a withdrawal order under Rule 14A will only come into force on the first day of the succeeding month following the date of the formal order.

In a practical sense, a taxpayer cannot report their true liability until the registration profile is officially changed on the system. Because of this central portal bottleneck, the merchant is legally and technically blocked from reporting excess liabilities incurred in April and May until July 11—nearly three months after the initial breach.

This lag is not merely procedural; it is a structural paralysis. For three months, the merchant is trapped in a legal vacuum where the digital portal prevents them from paying what they owe, penalising them directly for expanding their commercial footprint.

III. Article 300A and the Destruction of Commercial Credibility: The Impact on B2B Customers

The cascading negative impact of this rule extends far beyond the individual merchant, severely damaging their supply chain network and violating Article 300A (Right to Property) of their corporate clients. The Rule 14A portal lock-in prevents the merchant from updating April and May invoices above the ₹2.5 lakh tax level, resulting in penalising their B2B clients by denying them Input Tax Credit on purchases. This commercial fallout destroys the trader’s credibility, and without receiving eligible ITC on time, clients abandon the merchant.

The Input Tax Credit Breakdown

Because the portal prevents the merchant from updating their invoices to reflect the true, higher output tax details during April and May, their B2B customers suffer immediately by being unable to claim their legitimate Input Tax Credit (ITC) on those purchases.

The Supreme Court and various High Courts have consistently held that ITC is a vested financial asset, constituting “property” under Article 300A. Denying a purchasing business its right to claim ITC due to a technical lock-in imposed on their supplier amounts to an unconstitutional deprivation of property without the authority of substantive law.

Destruction of Business Credibility

In the modern B2B ecosystem, cash flow depends entirely on the seamless, monthly passing of ITC. When a small enterprise is forced by law to withhold credit from its buyers for months on end, the consequences are severe:

• Corporate clients face unexpected tax stickiness and cash crunches.
• Customers inevitably view the supplier as non-compliant or high-risk.
• Buyers abandon the growing small business in favour of larger, established competitors not shackled by Rule 14A restrictions.

By destroying the commercial credibility of the trader, this rule creates a constructive ban on trade. It alienates customers, drives down revenue, and systematically destroys the market standing of an enterprise at the exact moment it attempts to scale. It also prevents the merchant from declaring actual tax liability and penalises the merchant by charging interest on tax liability for delayed reporting—which is not the fault of the merchant but a consequence of the technical lock-in.

In a mature digital economy, the fundamental purpose of tax technology and governance is to build a frictionless ecosystem. The state’s responsibility is to make laws easy to follow, lower compliance thresholds, and actively encourage taxpayers to grow their businesses. When businesses flourish, they naturally pump more revenue into the national treasury.

Rule 14A represents a regression in this digital mandate. Instead of acting as an administrative catalyst, it turns growth into a compliance trap. It forces a zero-sum choice upon small merchants: either artificially cap business growth to stay safely under the ₹2,50,000 limit, or accept a multi-month compliance freeze, invasive physical scrutiny, broken supply chains, and unhappy clients.

Comprehensive Constitutional & Operational Matrix

Conclusion

Notification No. 18/2025–Central Tax exposes a sharp disconnect between the government’s digital ambitions and the rigid realities of its tax rules. By freezing amendments, delaying exit operational dates, and choking the flow of Input Tax Credit, Rule 14A actively punishes the exact behaviour a healthy economy should reward: business expansion.

To prevent these provisions from being struck down under Articles 14 and 19(1)(g) as a disproportionate restriction on trade, the GST Council must realign the portal’s logic. The system must allow immediate, real-time upgrades and seamless mid-month transitions, ensuring that increased revenue for the merchant translates into a faster, hassle-free contribution to the national treasury.
