Thomson Reuters launches ONESOURCE+, the AI-powered Intelligent Compliance Network

TORONTO, ON – November 5, 2025 – Thomson Reuters (TSX/NASDAQ: TRI), a global content and technology company, today introduced ONESOURCE+. ONESOURCE+ is the only AI-powered Intelligent Compliance Network that brings together tax, trade, legal, and risk solutions to help enterprises drive efficiency, reduce risk, and unlock growth. Built as a scalable network—not a single platform—ONESOURCE+ connects data, content, and workflows through an open ecosystem to turn disconnected compliance activities into coordinated, outcome-driven operations for corporations worldwide.

"Thomson Reuters stands alone in delivering the only Intelligent Compliance Network connecting tax, trade, legal, and risk domains, powered by CoCounsel—our agentic AI built on deep expertise, trusted content, and proven technology across the compliance ecosystem. Navigating the intersection of commerce and compliance is a business imperative, and modern corporations are looking to AI to transform disconnected compliance functions into a competitive advantage," said Laura Clayton McDonnell, President, Corporates, Thomson Reuters. "It's time to start treating compliance as a way to propel business forward. To address these needs, Thomson Reuters is unveiling ONESOURCE+ to deliver embedded, connected, and intelligent solutions that help corporations thrive in a complex, fast-moving environment."

ONESOURCE+ integrates specialized tools from Thomson Reuters for corporate tax, trade, legal, risk, and compliance professionals. It addresses the core challenge many businesses are having developing a collaborative view of their exposures to global tax, regulatory, legal, and supply chain risks, and provides a critical backbone to support AI-powered analytics and workflow management tools. According to the Thomson Reuters Future of Professionals Report, more than half of respondents said their organizations lack the required context to complete tasks that are part of cross-functional corporate governance and compliance workflows. Nearly half said they lacked a continuous, cross-functional view of data and insights and governance for workflows.

“In today's complex landscape, businesses are facing an unprecedented confluence of forces: rapid digital transformation, the growing adoption of AI, and relentlessly evolving regulatory requirements,” added Clayton McDonnell. “While 80% of C-Suite leaders recognize cross-functional collaboration as critical to business success, these functions often remain isolated, leading to operational inefficiencies, heightened risk exposure, and missed strategic opportunities.” 

Thomson Reuters is uniquely positioned to help businesses navigate this evolution toward more cross-functional efficiency. Its portfolio spans the industry’s leading tax, trade, legal, risk, and compliance solutions. By connecting these critical workflows in a single network, Thomson Reuters delivers a truly integrated, intelligent view that no single point solution provider can match.
