India-based Global Capability Centres (GCCs) have emerged as strategic hubs for multinational companies to manage complex global tax operations, including corporate tax, indirect tax, transfer pricing, and litigation, according to a whitepaper released by Deloitte India.The report, titled Transforming Global Tax Functions: The GCC Advantage, highlights how GCCs are evolving beyond back-office functions to offer high-value tax expertise, driven by a combination of deep technical capabilities, digital transformation, and cost efficiency.“GCCs have become an integral part of the global tax ecosystem, providing organisations with a competitive edge in managing their tax functions,” the whitepaper noted, as quoted ANI. Authored by Manisha Gupta, Partner at Deloitte India, the report also points to a surge in the establishment of tax Centres of Excellence (CoEs) within Indian GCCs.The findings reveal that 76 per cent of respondents surveyed already run global tax processes from their Indian GCCs, underscoring the country’s growing significance in enterprise tax transformation. “As more organisations pursue centralising tax functions, many have already established a tax CoE. The focus is now on key tenets and building blocks for scaling these centres successfully,” the paper stated.India’s GCC ecosystem has rapidly expanded, with over 1,700 GCCs employing 1.9 million professionals and generating $64.6 billion in revenue as of 2024. The sector is projected to grow to $105 billion by 2030, housing more than 2,400 centres and employing 2.8 million people.Key GCC hubs in India include Bengaluru, Hyderabad, Pune, Chennai, Mumbai, and the National Capital Region (NCR). The whitepaper adds that nearly 40 per cent of all digital transformation projects are currently being executed through these centres.The report also highlights a shift in GCC focus from data processing to knowledge processing, with newer entrants emerging from geographies such as Germany, the UK, Japan, and Nordic countries—signaling a diversification in global investment sources and functions.
