India boasts one of the world's largest pools of chartered accountants, with over 100,000 registered CA firms. Yet, paradoxically, the nation has not produced a single home-grown audit or consulting powerhouse capable of rivaling global giants like EY, KPMG, Deloitte, or PwC—collectively known as the 'Big Four'. This significant 'Big Four gap' in India is rooted in a complex interplay of historical regulatory constraints, challenges in accessing capital, and restrictive government procurement norms.
The Dominance of Global Players
The global Big Four firms maintain a formidable presence in India, operating through local partner firms and dominating both statutory audit and advisory services. Their collective revenue in India was estimated at approximately ₹38,500–₹38,800 crore in fiscal year 2024. This figure is projected to surge to an impressive ₹51,000–₹52,000 crore by FY26, a substantial rise from over ₹45,000 crore in FY25. Consulting services, particularly technology consulting, have been a major growth engine, accounting for more than ₹25,000 crore of their FY24 revenue.
Historical Regulatory Hurdles
A key factor limiting the scale of Indian CA firms has been the Chartered Accountants Act of 1949. This legislation imposed stringent restrictions, including limitations on advertising services beyond what the Institute of Chartered Accountants of India (ICAI) permitted, and crucially, barred firms from raising capital from external investors. These rules effectively prevented Indian firms from leveraging outside funding to expand their operations and build scale.
Although an amendment to the Act in 2006 and subsequent rules in 2008 allowed partnerships with other professions—such as company secretaries, lawyers, and engineers—the industry remains highly fragmented. Data from October 2025 shows that out of 100,138 registered CA firms, only 2,129 had six or more partners. Even more strikingly, ICAI data from 2022 revealed that fewer than 1% of firms had over 10 partners, with only 10 firms boasting more than 50 partners. In FY26, merely 25 audit firms handled 10 or more listed companies, while 649 audited just one.
Government Procurement Barriers
Government procurement practices have also presented a significant obstacle for smaller Indian firms. India's 2025 Manual for Procurement of Consultancy Services highlighted that several government departments frequently set minimum turnover requirements for consultancy assignments at five to ten times the estimated project cost. Furthermore, a Department of Expenditure review found that past firm experience often outweighed the qualifications of individual professionals proposed for a project, and some tenders mandated more employees than actually required for the job. These conditions, as noted by the memorandum, could "unduly restrict competition."
However, some states are pioneering change. Maharashtra, for instance, revised its approach in 2023, lowering the minimum turnover requirement to ₹15 crore for companies and ₹2 crore for NGOs, while also removing the prior public-sector experience mandate. These changes led to a surge in participation, with over 35 firms joining the state panel compared to just a handful previously.
ICAI's Transparency Push and Resistance
In an effort to enhance transparency, ICAI introduced Global Networking Guidelines in February 2026. These guidelines mandated CA and management consultancy firms to formally register their affiliations with overseas networks, disclose agreements, appoint nodal officers, and submit annual information including revenue, partners, staff, and payments. However, these requirements faced considerable resistance from global networks, particularly regarding the disclosure of sensitive information like royalty structures, technology-licensing fees, and fee-sharing arrangements. Consequently, ICAI placed the guidelines on hold in July 2026, partly due to questions raised by the Ministry of Corporate Affairs concerning the scope of ICAI's regulatory powers.
Towards a Stronger Home-Grown Sector
Despite these challenges, some initiatives are underway to bolster Indian firms. In 2024, ICAI revised its rules on mergers, leading to approximately 1,000 approved mergers between February and August 2026. The February 2026 Budget also included tax measures specifically designed to support home-grown accounting and advisory firms. Looking ahead, ICAI is preparing amendments to the CA Act that could recognize groupings of firms, facilitate external capital investment into Indian accounting firms, and expand the scope of CAs in consulting and advisory work. Such significant changes would, however, require approval from both the government and Parliament.
Ultimately, the absence of a home-grown 'Big Four' in India is not a reflection of a talent deficit. Instead, it underscores the systemic challenges Indian CA firms face in accessing capital, consolidating operations, competing for substantial government contracts, and operating within a regulatory framework that has historically limited their ability to achieve scale.
