Tata Consultancy Services (TCS)

India's largest IT services company by revenue and headcount

Overview

Tata Consultancy Services, part of the Tata group, was established in 1968 and describes its work as spanning the full technology stack “from infrastructure to intelligence”.[4] The Tata group reports that TCS operates 194 service delivery centres and has staff in 56 countries.[4] For the fiscal year ended 31 March 2026 TCS reported revenue of ₹2,67,021 crore; Business Today reported a closing headcount of 5,84,519.[3] The company reports in Indian rupees, and its fiscal 2026 revenue declined slightly in U.S.-dollar terms even as rupee revenue grew, a result of currency movements. TCS does not report a separate managed services revenue line, so the share of revenue from run-and-operate contracts cannot be isolated from its application development, consulting and business process work.
