SHERIDAN, WYOMING – April 12, 2026 – Thomson Reuters is deepening its integration of artificial intelligence across legal, tax, audit, and compliance workflows, offering professionals a suite of tools designed to compress research time, automate routine tasks, and surface actionable insights from verified content. The company's AI push centers on CoCounsel — a platform family spanning legal, tax, and audit functions — built on content sourced from Westlaw's 150 years of legal data and the editorial work of more than 650 attorney-editors contributing to Practical Law. For law firms, corporate legal departments, and accounting practices grappling with growing workloads and tighter margins, the shift represents a fundamental change in how professional knowledge work is structured.
CoCounsel: AI Across Legal, Tax, and Audit
CoCounsel Legal unites research, drafting, and analysis in a single interface, drawing on Westlaw and Practical Law content to handle complex legal tasks that previously required hours of manual work. Law firm Harris, Hardy & Johnstone has used CoCounsel to reduce hour-long document reviews to minutes, a time saving that directly affects billing efficiency and staff capacity. Brinks deployed CoCounsel to streamline legal operations, reduce outside counsel spending, and support global compliance — demonstrating that the tool's utility extends beyond litigation into operational and transactional functions.
CoCounsel Tax targets accounting firms handling high volumes of client deliverables. It centralizes trusted tax sources alongside firm-specific data, accelerating research and the preparation of client-facing outputs. SafeSend and Ready to Review automate 1040 return preparation, eliminating manual data entry and allowing tax professionals to scale capacity without proportional headcount increases. Ready to Advise converts client data into specific tax strategies, positioning accountants as advisors rather than processors.
Trade Compliance and Risk Products
Thomson Reuters addresses global trade complexity through its ONESOURCE product line. ONESOURCE Global Classification AI automates Harmonized System code classification for import and export, delivering what the company describes as fast, accurate, audit-ready results across international jurisdictions. ONESOURCE Denied Party Screening monitors more than 750 global sanctions lists automatically, reducing the manual overhead that compliance teams face as sanctions regimes grow in scope and frequency.
ONESOURCE Pagero handles e-invoicing compliance globally, centralizing tax data and automating reporting across VAT, GST, and sales tax jurisdictions. For companies managing foreign trade zones, ONESOURCE Foreign Trade Zone Management links supply-chain data to compliance workflows, targeting duty savings and improved cash flow. The CLEAR platform serves investigations and risk professionals, surfacing connections across public records and screening for adverse media exposure globally.
Platforms for Government and Enterprise
Thomson Reuters also serves government legal departments, courts, prosecutors, and public defenders. The Pascua Yaqui Tribe's legal team used HighQ — a collaboration and workflow automation platform — to transform matter management, reducing administrative friction in an environment where legal resources are constrained. HighQ combines secure document collaboration, automated workflows, and client engagement tools in one platform.
For enterprise tax functions, ONESOURCE Income Tax handles federal, state, and international corporate tax returns, while ONESOURCE Tax Provision calculates tax estimates automatically to accelerate the financial close process. Oracle users can consolidate compliance into ONESOURCE, reducing the complexity of managing separate tax and trade systems across multiple jurisdictions. Guided Assurance supports audit engagements by identifying risks using AI and automating compliance checks throughout the engagement lifecycle.
Why it matters
For legal professionals at small and mid-sized firms, AI-assisted research and drafting tools lower the cost of competing with large firms that maintain extensive in-house research teams. Solo practitioners and small practices gain access to the same depth of Westlaw content and Practical Law guidance without requiring specialist staff, which changes the economics of handling complex matters. Clients at these firms benefit from faster turnaround and, in some cases, lower fees as review times drop from hours to minutes.
For corporate compliance and trade teams, automated denied-party screening across 750-plus lists and AI-driven HS code classification reduce the risk of regulatory violations that carry significant financial and reputational penalties. As global trade rules and sanctions regimes shift rapidly, manual compliance processes create exposure gaps; automated continuous monitoring closes those gaps in near real time. Accounting professionals face a direct change in their day-to-day role: tools like Ready to Advise and CoCounsel Tax push routine preparation tasks toward automation, reorienting practitioner time toward advisory work that commands higher fees and deeper client relationships.
