PowerPlan Tax Provision vs Tax Series

PowerPlan Tax Provision is a SaaS product for income tax provision aimed at tax departments in asset-intensive businesses. It handles complex ASC 740 and ASC 980 calculations, automates repetitive work, and eliminates manual reconciliations. Running on the PowerPlan NXT platform alongside Tax Fixed Assets, it automatically uses data from that product in provision calculations without exports, imports, or custom integrations. 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. Pricing is available on request; the product page offers a demo request rather than a stated price.

Tax Series is web-native corporate tax software for corporate income tax processes, with shared data used across tax work. Its modules cover worldwide provision reporting under ASC 740, corporate tax compliance, and BEPS reporting. Provision supports calculations under U.S. GAAP or IFRS. Compliance automates corporate tax calculations and population of forms including 5471, 8865, and 8858; BEPS supports Country-by-Country reporting and master and local files. Data Collector assigns packages to preparers, reviewers, and approvers and provides real-time project monitoring. Web Services supports two-way data transfer with client systems, data validation, and calculation triggers. A single database also supports planning, audit support, legal entity maintenance, tax calendar, and document management. The vendor describes the product as well suited to medium and large multinational corporate clients, and it supports U.S. corporate taxpayers and multinational corporations. Pricing is on request. Prospective clients can use it for a full tax cycle at no cost through a proof of concept, typically a 2–10 week process. After subscription termination, clients receive three months of read-only access to retrieve data.
