What ONESOURCE Tax Provision is
ONESOURCE Tax Provision automates corporate tax estimates and helps streamline financial close and reporting. Its calculation engine generates tax entries and is designed for complex tax scenarios, including current and deferred provision work. It can automate tax attributes such as net operating losses and valuation allowances, and supports rate reconciliation and provision-to-return workflows.
Reporting includes industry-standard and custom reports, application-wide filtering, and drill-down from consolidated figures to entity-level detail. Configurable journal entries connect the product with ERP systems across jurisdictional levels. Microsoft Excel Workpapers supports data exchange in both directions. The software can combine structured and unstructured information from multiple sources, extract data for other applications, and use APIs for imports and exports, including scheduled or triggered imports. The web-based Global Access add-on lets colleagues enter data remotely with local language and currency support, configurable permissions, controls, and sign-offs. Thomson Reuters describes the reports and results as audit-ready. Pricing is available on request. The product is presented for upper-mid-sized and enterprise corporations, including multinational enterprises.
