Thomson Reuters, a global leader in intelligent information and solutions for professionals, has officially launched the latest iteration of its CoCounsel Tax, Audit & Accounting platform. This significant upgrade introduces a fully agentic artificial intelligence (AI) system designed to streamline and enhance the complex workflows of tax, audit, and accounting practitioners. Building upon the foundation laid by its initial release last year, this new version represents a substantial leap forward in AI-driven professional services, promising greater efficiency, accuracy, and strategic focus for users.
A New Era of AI in Professional Services
The unveiling of this advanced CoCounsel platform marks a pivotal moment in the integration of AI into the core operations of tax, audit, and accounting firms. The original CoCounsel, introduced to the market, aimed to leverage AI to assist professionals. However, this next generation moves beyond mere assistance to embody a fully agentic capability. This means the AI can autonomously plan tasks, select and utilize the most appropriate tools for the job, and execute complex processes with minimal human intervention until the final review stage.
David Wong, Chief Product Officer at Thomson Reuters, emphasized the transformative nature of this release in a recent blog post. "Our next generation of CoCounsel is a fully agentic platform that plans the work and uses the right tools for the job," Wong stated. He further elaborated on its sophisticated functionalities: "It writes and runs code to complete calculations, works directly with spreadsheet data, creates multi-tab workbooks with formulas, analyzes long and complex documents, and turns the work into a finished deliverable you can review and refine. We built it to run on any frontier model, so the platform keeps improving no matter who is ahead in the model race." This strategic architectural choice ensures the platform’s longevity and adaptability in the rapidly evolving AI landscape, preventing vendor lock-in and promising continuous improvement.
Joel Hron, Chief Technology Officer at Thomson Reuters, echoed this sentiment, highlighting the platform’s commitment to reducing the manual burden on professionals. "The aim is to carry more of the task through to work product, rather than leave the professional to reconstruct pieces of the answer across a disparate set of tools," Hron explained in a separate blog post. This focus on end-to-end task completion is crucial for firms aiming to optimize their resources and elevate the value of their services.
Addressing the Nuances of Professional Judgment
A core challenge in applying AI to tax, audit, and accounting has been the inherent need for professional judgment. These fields are replete with intricate decisions, such as interpreting which regulations apply, how specific client facts align with legal frameworks, and identifying the governing authority for particular periods. The latest CoCounsel Tax, Audit & Accounting platform has been meticulously engineered to address these nuances. Thomson Reuters asserts that the platform is designed to make these critical judgment calls accurately, grounding every calculation and analysis in the correct authoritative sources.
The platform provides a transparent audit trail, allowing professionals to understand precisely how the AI arrived at its conclusions. This visibility is paramount for validation and builds the necessary confidence for practitioners to rely on the AI’s output. "For tax, audit, and accounting professionals, that means faster execution without sacrificing the quality of the result," the company stated. By automating repetitive tasks and standardizing workflows, CoCounsel empowers teams to increase their capacity, tackle more complex and high-value projects, and dedicate more time to strategic initiatives that are often sidelined by manual execution.
A Foundation of Innovation and Integration
CoCounsel Tax, Audit & Accounting is built upon the broader CoCounsel platform, which also underpins other advanced Thomson Reuters tax solutions. These include Ready to Review, a cloud-based agentic AI tax workflow application, and Ready to Advise, an AI-powered tax planning advisory solution. This integrated ecosystem ensures a cohesive user experience and allows for seamless data flow between different applications.
Thomson Reuters has committed to continuously enhancing the CoCounsel Tax, Audit & Accounting platform, with new capabilities and features slated for regular integration. A key aspect of this strategy is direct connectivity with the tools and systems that tax, audit, and accounting teams already utilize. This approach ensures that new functionalities are seamlessly incorporated into existing workflows, minimizing disruption and maximizing adoption.
The Multi-Model Strategy and Fiduciary-Grade AI
A significant differentiator of the CoCounsel platform is its multi-model strategy. This approach allows the system to leverage the optimal AI model for each specific task, ensuring peak performance regardless of advancements in the AI landscape. "It’s built on a multi-model strategy, so customers are always working with the optimal model for the task, no matter how the technology changes," the company explained.
Crucially, the platform remains firmly grounded in authoritative sources. This includes the extensive Thomson Reuters accounting research engine, Checkpoint. Checkpoint houses a vast repository of over 12 million primary source documents and proprietary analytical content, meticulously curated and maintained by hundreds of experts, including Certified Public Accountants (CPAs) and tax attorneys. This ensures that the AI’s reasoning and outputs are always based on the most current and reliable information.
Furthermore, CoCounsel adheres to the Thomson Reuters Fiduciary-Grade AI standard. This commitment to transparency and accountability is essential for professionals who operate under strict ethical and regulatory obligations. It provides practitioners with the confidence and clarity required to validate the AI’s work and ensure it meets the highest professional standards.
Key Capabilities of the Enhanced Platform
The latest version of CoCounsel Tax, Audit & Accounting introduces a suite of powerful capabilities designed to transform professional workflows. While the original article snippet did not detail these specific capabilities, based on the platform’s description and the stated goals, we can infer key functionalities:
- Automated Document Analysis: The AI can process and analyze lengthy and complex documents, extracting relevant information and identifying key clauses or data points. This is invaluable for tasks such as due diligence, contract review, and compliance checks.
- Intelligent Calculation and Modeling: The platform can perform intricate calculations, create sophisticated financial models, and generate multi-tab workbooks complete with dynamic formulas. This extends to complex tax computations and audit testing scenarios.
- Data Integration and Manipulation: CoCounsel seamlessly interacts with spreadsheet data, allowing for direct manipulation and analysis. This eliminates the need for manual data entry or complex data import/export processes.
- Work Product Generation: The AI is capable of producing finished deliverables, such as reports, memos, or audit workpapers, that can be directly reviewed and refined by the professional. This significantly reduces the time spent on formatting and compilation.
- Reasoning and Justification: A standout feature is the AI’s ability to articulate its reasoning process, linking its conclusions back to specific authoritative sources. This provides the transparency necessary for professional validation and client trust.
The Judgmental AI Difference
Joel Hron further elaborated on the critical distinction of CoCounsel’s AI capabilities, emphasizing its focus on "why" the work is correct, not just "that" it is correct. "We didn’t just build a tool that does math. We built one that knows why the math is right," Hron stated. He explained that while code execution is becoming a baseline capability across the industry, the true challenge lies in ensuring the AI reasons from accurate facts and the correct authority before any calculations are performed.
"What’s hard is making sure the system is reasoning from the right facts and the right authority before it ever runs a calculation. We built that judgment in, grounded in content that’s kept current and tested by the people who actually do this work so a professional can check it themselves rather than take our word for it," Hron added. This emphasis on embedded judgment, validated by domain experts and current authoritative content, positions CoCounsel as a uniquely reliable AI partner for professionals.
Availability and Future Outlook
The latest version of the CoCounsel Tax, Audit & Accounting platform is now available to all customers in the United States. Thomson Reuters has indicated that further enhancements and expanded functionalities will be rolled out progressively, reinforcing their commitment to continuous innovation and customer-centric development.
This launch signifies a major step in the evolution of AI-powered professional tools. By focusing on agentic capabilities, deep integration with authoritative content, and transparent reasoning, Thomson Reuters is setting a new benchmark for how AI can augment and transform the critical work of tax, audit, and accounting professionals, ultimately leading to greater efficiency, accuracy, and strategic value for businesses and their advisors.
