"The integration of CoCounsel into our research process has been a game-changer. We get verifiable answers in a fraction of the time, which directly improves our client response and advisory capacity."

Mark D., Partner · May 2026

"Automating the initial 1040 prep with their AI tools has transformed our tax season. It's freed up so much time for our team to focus on complex returns and client questions instead of data entry."

Julia S., Senior Tax Accountant · April 2026

"The power is undeniable, but the learning curve is steep. Getting the full suite implemented and training the team required a significant up-front time investment. It's not a plug-and-play solution."

Brian K., Small Firm Owner · May 2026

"CoCounsel Audit has brought a new level of standardization to our engagements. The citation-backed insights make our review process faster and more robust. It's a huge confidence booster."

Chen L., Audit Manager · March 2026

Comparison

How it compares

Thomson Reuters vs. Wolters Kluwer CCH: Both are titans in the tax and accounting software space. Choose Thomson Reuters for its aggressive integration of generative AI across its entire workflow, especially with tools like CoCounsel for research and advisory. Its strength lies in unifying trusted content with AI assistance. Opt for Wolters Kluwer if your firm is deeply embedded in their existing CCH Axcess ecosystem and prefers its established workflow, which also incorporates AI but may have a different integration philosophy. The decision often comes down to existing platform loyalty and which AI implementation best fits your firm's specific needs.

The decision

Is it worth it?

Who It's For

Why Accounting, Bookkeeping & Tax choose this tool

🎯
Built for
Tax and accounting firms seeking a unified, AI-driven platform for compliance, research, and workflow automation across all client services.
In-Depth Overview
For accounting and tax professionals, Thomson Reuters moves beyond basic automation by embedding generative AI directly into core workflows. Products like CoCounsel Tax transform research by allowing you to query trusted sources and your own firm's data simultaneously, delivering verifiable, citation-backed answers for client deliverables. This significantly reduces the risk associated with generic AI tools. The platform's strength is its breadth. With 'Ready to Review,' firms can automate 1040 return preparation, eliminating manual data entry. For corporate needs, the ONESOURCE suite manages complex global indirect tax determination (VAT, GST) and streamlines financial close. Proof of its impact is found in customer stories where firms, using CoCounsel, reduced hour-long review processes to minutes. By integrating AI with a foundation of expert-led content, Thomson Reuters enables firms to scale capacity, ensure compliance, and shift focus from routine tasks to strategic client advisory.
