Thomson Reuters ONESOURCE in corporate tax
ONESOURCE is Thomson Reuters's enterprise tax management suite covering corporate income tax, indirect tax, tax provision, transfer pricing, and international tax. For large corporations with dedicated tax departments, ONESOURCE is often the tax system of record.
How Thoughtwave integrates ONESOURCE
Our engagements cover:
- ONESOURCE APIs for tax data access and workflow integration.
- ERP integration for tax provision and compliance data flowing between the tax team and the finance system.
- AI-augmented tax workflow including anomaly detection on tax filings and compliance-research assistance.
- Tax data management for clients running complex multi-entity, multi-jurisdiction tax structures.
- Transfer pricing documentation workflow with AI-assisted narrative generation.
Authentication and governance
ONESOURCE integration uses enterprise-authentication patterns aligned to Thomson Reuters's platform and the client's tax-department governance posture.
When ONESOURCE fits
For large corporations where the tax department operates as a distinct function with dedicated staff and specialized workflows, ONESOURCE is typically the tax-platform choice. Our engagements deliver AI augmentation on top of the ONESOURCE data for efficiency gains the tax team can measure directly.
