Thomson Reuters launches AI-powered tax compliance solution

11 Nov 2026

ONESOURCE Sales and Use Tax AI combines agentic AI with tax expertise to automate compliance processes, reduce manual work and give tax professionals more time to focus on higher-value activities.

Thomson Reuters has launched ONESOURCE Sales and Use Tax AI, an AI-powered compliance solution designed to automate routine tax reporting while keeping tax professionals in control of review and approval.

Powered by CoCounsel, the solution applies agentic AI to tasks including data import, validation and tax return mapping. Early customers report reducing time spent on routine reporting by up to 65% and audit exposure by up to 75%.

Towards more automated tax compliance

The launch reflects the Thomson Reuters vision of “Touchless Compliance”, where AI and automation handle more of the routine compliance process while professionals retain oversight of final outputs.

“Compliance should be touchless by default, manual by exception. This isn't just automation; it's a fundamental reimagining of the tax function, freeing professionals to drive strategic business advantage,” said Ray Grove, Head of Product, Corporate Tax and Trade at Thomson Reuters.

The solution provides automated validation and audit trails alongside human review and sign-off, helping tax teams reduce manual intervention while maintaining control over compliance decisions.

While ONESOURCE Sales and Use Tax AI is currently available for US sales and use tax obligations, the broader ONESOURCE Indirect Compliance powered by CoCounsel brings AI-powered compliance automation to tax teams managing requirements across multiple jurisdictions.

It forms part of the wider ONESOURCE indirect tax portfolio, which connects tax determination, e-invoicing, reconciliation and indirect tax compliance in a more integrated workflow.
