Thomson Reuters (TSX/Nasdaq: TRI), a global content and technology leader, announced on November 5, 2025, the launch of new agentic AI solutions designed for professionals in Tax, Audit, Legal, and Compliance fields. Central to this expansion is ONESOURCE+, an intelligent compliance network that integrates tax, trade, legal, and risk solutions to enhance efficiency, reduce risk, and stimulate growth. ONESOURCE+ features AI innovations such as Sales and Use Tax AI, which automates filings across thousands of jurisdictions cutting preparation time by 40-60% while minimizing audit risks, and Global Classification AI, which streamlines product classification for global trade with audit-ready documentation and continuously learning algorithms. Building on earlier releases of CoCounsel Legal with Deep Research and CoCounsel Tax, Audit and Accounting, Thomson Reuters has upgraded CoCounsel Tax, Audit and Accounting to include agentic AI capabilities like "Ready to Review, " which automates U. S. 1040 tax return preparation from source documents, significantly reducing manual effort. A forthcoming feature, CoCounsel Document Analysis, will enable auditors to automate complex workflows by extracting data for vouching and testing, and automatically generating cited workpapers, freeing professionals for higher-level tasks. Expanded content including guidance from AICPA, FASB, GASB, IFRS, and sustainability standards is now integrated into a unified AI-driven workflow. In the legal domain, CoCounsel Legal is advancing with three new beta features employing a next-generation agentic AI framework: bulk legal document review capable of processing up to 10, 000 documents for diligence and risk assessment; customizable agentic workflows that independently manage intricate legal processes using Westlaw and Practical Law content; and the ability for lawyers to create, save, share, and refine workflow plans combining Thomson Reuters legal tools with firm-specific knowledge. These capabilities are slated for release to U. S.

users in early 2026. David Wong, Chief Product Officer, emphasizes that Thomson Reuters is uniquely positioned to deliver professional-grade agentic AI by combining advanced reasoning models, extensive domain expertise, trusted content, and familiar professional tools. Across all applications, these AI solutions drive substantial time savings through automation, lower risk via transparent, audit-ready documentation, and improve accuracy by blending AI with authoritative content. They empower professionals to delegate complex, multi-step tasks and concentrate on strategic decision-making. Thomson Reuters will present these innovations to over 5, 000 customers at the SYNERGY 2025 Conference in Orlando from November 5-12. For more information, visit the Thomson Reuters Innovation Blog.
