The Informal Economy’s Formal Problem: Why GST Compliance Costs Are Crushing India’s Small Businesses

The Goods and Services Tax, introduced as India’s most significant indirect tax reform in decades, was designed with multiple ambitious objectives: unifying a fragmented patchwork of state-level taxes into a single national framework, eliminating cascading taxation, and — critically — bringing a much larger share of India’s vast informal economy into the formal, taxed fold by creating compliance incentives built into the system’s input tax credit mechanism. Several years into implementation, the reform’s impact on India’s smallest businesses tells a more complicated story than the formalisation narrative suggests.

The Compliance Burden in Practice

For a large, well-resourced company with a dedicated accounting department, GST compliance is a manageable, even beneficial, administrative requirement. For a micro-enterprise — a small manufacturer, a neighbourhood retailer, a single-person service provider — the same compliance requirements impose a fixed cost that does not scale down proportionally with business size. Monthly and annual filing obligations, reconciliation requirements between a business’s own filings and those of its suppliers and customers, and the technical complexity of the GST portal itself have created a compliance burden that many small business owners report spending a disproportionate share of their limited time and resources managing, often by hiring intermediaries they cannot easily afford.

The Unintended Incentive to Stay Small

This dynamic has produced a counterintuitive and underdiscussed consequence: rather than incentivising small businesses to formalise and grow, the structure of compliance thresholds has in some cases created an incentive to deliberately remain below the registration threshold, foregoing growth opportunities to avoid the compliance burden that growth would trigger. This is precisely the opposite of what a formalisation-oriented tax reform should produce, and it reflects a design tension between simplicity for the tax authority and proportionality for the smallest taxpayers that the current GST framework has not fully resolved.

A second, related issue is working capital strain. The input tax credit mechanism, while elegant in design, requires businesses to pay GST on their purchases upfront and claim credit only after filing and reconciliation, a process that can take weeks. For small businesses operating on thin working capital margins, this lag between cash outflow and credit recovery has, in practice, tightened liquidity in ways that disproportionately affect the smallest, least capitalised enterprises — precisely the segment the reform aimed to bring into the formal economy.

A tax reform that formalises large businesses while pushing small ones toward deliberate informality has not failed at formalisation. It has simply formalised selectively, along lines of size rather than along lines of economic activity.

What Course Correction Would Look Like

The GST Council has periodically simplified compliance requirements for small taxpayers, including simplified quarterly filing options for businesses below certain turnover thresholds, and these adjustments represent genuine, if incremental, progress. A more comprehensive fix would likely require a graduated compliance regime that scales filing complexity and frequency more smoothly with business size, rather than the current structure where crossing a single threshold triggers a substantial jump in compliance obligation. Until that redesign occurs, the formalisation the reform was meant to drive will likely continue to arrive unevenly — readily for large enterprises with the resources to absorb compliance costs, and considerably more reluctantly for the small businesses that form the overwhelming majority of India’s enterprise count.
