CoCounsel Tax, Audit and Accounting Adds Agentic AI Capabilities for Automated Return Preparation and Audit Workflows
Thomson Reuters is further advancing the capabilities of CoCounsel Tax, Audit and Accounting with several significant AI-powered developments designed to transform tax preparation and audit workflows:
- Ready to Review – By processing source documents and prior-year returns, this agentic AI tax workflow application automates U.S. 1040 Form tax return preparation, generating returns that are ready for professional review.
- CoCounsel Document Analysis – Coming January 2026, auditors and accounting professionals will be able to automate complex audit workflows at scale. Professionals will be able to delegate client document review to this agentic AI solution, which extracts critical data for vouching and substantive testing, produces cited workpapers, and frees professionals to focus on judgment-intensive work.
Indiana-based CLH CPAs & Consultants had the opportunity to try Ready to Review and it offered transformative time savings for the firm. “Reducing return preparation time by approximately an hour on each simple 1040 is significant in terms of efficiency gains. For firms like ours, these time savings will be a game changer,” says Bob Lange, Partner at CLH.
The company has also expanded CoCounsel Tax, Audit and Accounting’s knowledge base to include authoritative content from AICPA, FASB, GASB, and IFRS (including sustainability standards) now integrated directly into CoCounsel’s single AI-guided workflow.
