ONESOURCE Tax Provision vs PowerPlan Tax Provision

ONESOURCE Tax Provision automates corporate tax estimates and supports financial close and defensible reporting. Its calculation engine creates tax entries automatically for complex tax scenarios and can handle 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, application-wide filtering, and drill-down from consolidated amounts to entity-level detail. Configurable journal entries connect it with ERP systems across jurisdictional levels. Microsoft Excel Workpapers can exchange data in both directions. The software collects structured and unstructured data from multiple sources, extracts information for other applications, and provides APIs for imports and exports, including scheduled or triggered imports. The web-based Global Access add-on lets colleagues enter information from any location with local language and currency support. It also provides configurable controls, permissions, and sign-offs. Thomson Reuters describes the output as auditable and audit-ready. ONESOURCE University offers training packages, workshops, WebSeminars, courses, and certifications. The product is presented for upper-mid-sized corporations, multinational enterprises, and enterprise corporations. Pricing is available by contacting sales.

PowerPlan Tax Provision is a SaaS product for income tax provision aimed at tax departments in asset-intensive businesses.

Its tax engine covers regulated and non-regulated income tax calculations. Built-in dashboards and Data Hub libraries support analysis, and the Data Hub includes outbound APIs for data extraction. The SaaS model delivers functionality enhancements and compliance updates through quarterly releases. PowerPlan describes SOC 2 Type II certified infrastructure with continuous monitoring, third-party audits, and security controls. Integration with a client identity provider is required; SAML 2.0 is used by all modules except specified LDAP-integrated modules. Managed cloud services are described, and live phone and online case support is available Monday through Friday from 8:00AM to 8:00PM ET.
