EY Global Services is the global professional services organisation of EY, delivering assurance, tax, consulting and strategy services to clients in more than 150 countries. The firm employs approximately 400,000 people and works across industries and borders, serving clients that range from established companies in capital markets to startups navigating initial public offerings.

Its service lines are organised around four areas. Assurance services help organisations build trust and confidence in capital markets. Tax services are delivered globally across more than 150 countries. Consulting services address clients' most difficult challenges, including cybersecurity and technology transformation. Strategy services support clients through geopolitical shifts and public listings, among other transitions.

The firm's stated purpose is "building a better working world". It describes its approach as partnership-oriented, with professionals working alongside clients rather than at arm's length, and combines expertise across cybersecurity, technology transformation, sustainability and business strategy. EY places emphasis on diverse perspectives and inclusive teams as drivers of innovation, and on trust, confidence and long-term value creation.
