The "Big Four" in Dubai typically refers to the four dominant global professional accounting and management consulting networks—PricewaterhouseCoopers (PwC), Deloitte, Ernst & Young (EY), and KPMG—which maintain massive regional headquarters in the emirate. These firms employ thousands of professionals providing high-level audit, tax, consulting, and advisory services to governments, multinational corporations, and rapidly scaling regional enterprises operating throughout the Middle East.
