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.
