Indirect tax compliance software

Move from manual preparation to confident review

Indirect tax compliance is becoming more complex and increasingly digital. Fragmented data, evolving regulations, and limited resources make manual processes hard to sustain. ONESOURCE Indirect Compliance powered by CoCounsel automates the entire lifecycle. It combines up-to-date tax content, agentic AI, and expert insight to improve accuracy, increase efficiency, and help your team reduce risk of non-compliance as you scale.

Keep reporting requirements aligned with changing indirect tax rules through Thomson Reuters tax content which is validated and maintained by subject matter experts. The solution supports more than 70 jurisdictions and includes VAT/GST returns, EC Sales Lists, Intrastats, SAF-T, SII, digital reporting, prefills and e-filing requirements where available.

Content updates are incorporated automatically in advance of changes being released by tax authorities, so teams do not have to rely on manual monitoring alone or dedicate resources to constantly updating systems.

This combines software automation with authoritative tax expertise to help organisations manage changing obligations with greater confidence.

Focus review on the issues that require professional expertise and judgement. AI agents identify exceptions, including formatting errors, tax-rate validation issues, VAT ID errors, duplicates and unmapped tax codes.

Human-in-the-loop controls allow users to approve or reject suggestions before changes are applied, while clear explanations make each correction easier to review. The agents identify patterns, propose fixes and learn from accepted resolutions. The tax team remains in control.

Compare what should be filed with what the systems produce, and understand why differences exist before they become problems or turn into penalties.

Transactions are automatically reconciled against the general ledger and e-invoicing data. Integrated data feeds pull key e-invoicing fields (such as KSeF IDs, clearance tokens, and network reference numbers) directly into compliance imports to ensure accuracy and timely resolution. AI agents surface tax treatment mismatches with jurisdiction-specific resolution guidance, resolving mismatches and tax root causes in a single review action.

Give reviewers a clear record of what changed, why it changed and who approved it. Human approval points, audit trails and reversible actions keep automation visible and traceable.

Returns and supporting documentation can be assembled quickly and traced back to source data and systems. That makes internal sign-off easier and helps create defensible documentation for audit and regulatory review.

See patterns before they become exposure, and get the context to resolve them from the dashboard.

VAT/GST and exception data are automatically consolidated across entities and jurisdictions, surfacing input/output positions, net reclaimable amounts, and flagged transactions as they arise. Custom analytics can be generated on demand, pulling the exact report and visualization needed for a given entity, period, or issue. AI-driven insights turn raw compliance data into decision-ready analysis, letting users move from reviewing numbers to advising on them in a single step.
