Deloitte operates as a global network of legally independent member firms under one brand. Deloitte Touche Tohmatsu Limited (DTTL), a UK private company limited by guarantee, coordinates the network and does not itself serve clients. The network reported US$74.5 billion in aggregate FY2026 revenue and described its workforce as nearly 500,000 people. Its services include Audit & Assurance, Technology & Transformation, Strategy, Risk & Transactions, and Tax & Legal. The aggregate revenue is not DTTL standalone revenue.
Deloitte sells professional time, expertise and increasingly technology-enabled managed services. Revenue comes from four reported businesses: Audit & Assurance (statutory audits and assurance, which grew 5% in local currency in FY2026), Technology & Transformation (enterprise software, cloud, AI and engineering programs, up 2.5%), Strategy, Risk & Transactions (M&A, risk, restructuring and strategy advice, up 4.4%), and Tax & Legal (up 5.8%). Engagements are priced by time and materials, fixed fees or multi-year Operate contracts. Each member firm is a separate legal entity owned by its local partners, who share in profits after salaries and costs; DTTL coordinates brand, standards and strategy but does not provide client services.
