OIC CoCounsel overview
CoCounsel is an AI-driven compliance assistant in ONESOURCE Indirect Tax Compliance (OIC) that automates routine tasks while keeping you in control of every required review.
OIC CoCounsel works automatically during return preparation to detect common data issues, suggest corrections, and guide you through any required reviews. By the time a return reaches you, most of the tedious pre-work is already done.
CoCounsel follows a human-in-the-loop model: the system proposes fixes and automates routine adjustments, but you remain in control at every step. Every action taken and every suggestion made is transparently logged for audit purposes.
Key Benefits
- Fewer manual steps — error correction, data cleanup, and reconciliation are handled automatically.
- Earlier error detection — issues are caught during data import, not at filing time.
- Review-ready returns — by the time you open a return, CoCounsel has already validated and corrected the data.
- Full audit trail — every automated action and approval decision is recorded.
- Faster compliance cycles — more time for analysis; less time on repetitive fixes.
note
CoCounsel is available for all OIC jurisdictions at GA. Nine countries — Poland, Romania, France, United Kingdom, UAE, Singapore, Italy, Australia, and Spain — have additional specialist logic.
