ONESOURCE Tax Provision
What it is
ONESOURCE Tax Provision automates corporate tax estimates and supports the financial close and reporting. Its calculation engine generates tax entries automatically and is designed for complex tax scenarios; it can also automate tax attributes such as net operating losses and valuation allowances. The product covers current and deferred provision work, rate reconciliation, and provision-to-return.
Reporting includes industry-standard and custom reports, filtering across the application, and drill-down from consolidated amounts to entity-level detail. Configurable journal entries connect with ERP systems across jurisdictional levels, while Microsoft Excel Workpapers supports data movement in both directions. The software can manage multiple structured and unstructured data sources and extract information for other applications. APIs support 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, as well as configurable controls, permissions, and sign-offs. Thomson Reuters describes the output as audit-ready. The product is presented for upper-mid-sized corporations and multinational and enterprise corporations. Pricing is available by contacting sales.
