BDO USA, P.C.

BDO USA, P.C. is a leading professional services firm in the United States, providing assurance, tax, and advisory services. The firm's mission centers on delivering exceptional service to its clients and fostering an empowering environment for its employees. Headquartered in Chicago, Illinois, BDO USA operates as the U.S. member firm of BDO International Limited, a global network of independent accounting and advisory firms.

The firm offers a comprehensive suite of services, including audit and assurance, tax planning and compliance, and a broad range of consulting services such as management consulting, risk advisory, IT consulting, and financial advisory. BDO USA also provides specialized services like BDO Digital, BDO Wealth Advisors, and sustainability and ESG consulting. It serves a diverse client base, from publicly traded to privately held companies, across various industries including manufacturing, healthcare, private equity, technology, real estate, financial services, and government.

BDO USA is recognized as the 8th largest accounting and professional services firm in the U.S. by revenue, and is part of the fifth-largest global accounting network. In July 2023, the firm transitioned to an Employee Stock Ownership Plan (ESOP) corporation, a move financed by a $1.3 billion loan from Apollo Global Management, though this conversion is currently the subject of a class-action lawsuit. Matthew Becker is slated to become CEO on July 1, 2026, succeeding Wayne Berson, with Natalie Kotlyar serving as Board Chair. Recent developments include the acquisition of Horne LLP, a significant expansion, and the launch of BDO Government Services. The firm was also recognized by Fortune as one of the "100 Best Companies to Work For" in 2026 for the second consecutive year. However, BDO USA has faced scrutiny, including high deficiency rates in PCAOB audit inspection reports in 2024 and 2025, and a recent lawsuit alleging failure to detect financial problems at a client prior to bankruptcy.
