Thomson Reuters – Generative AI in Professional Services Report, 2025

The main theme of the report is the use of generative artificial intelligence (GenAI) in professional services.

Key findings include the widespread adoption of GenAI in industries such as legal services, tax, accounting, auditing, corporate risk and fraud, and government services. The report discusses the use of both free tools (e.g., ChatGPT) and paid solutions (e.g., Copilot) for business tasks. It is expected that GenAI will become a central part of daily workflows within the next five years. Challenges include integrating GenAI into organizational strategies and measuring return on investment (ROI), as well as a lack of policies and training on GenAI within organizations.
