In their own words
PowerPlan Tax Provision
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.
TaxCalc
TaxCalc is a UK accounting software platform for tax compliance, client management, and practice operations. Its products prepare personal, partnership, trust, and company tax returns, as well as statutory accounts. For Self Assessment, SimpleStep guides users through relevant sections, with an option to switch to HMRC-style forms. Calculations update in real time, and Check & Finish reviews a return before submission. Tax products submit directly to HMRC, while Accounts Production files statutory accounts to Companies House. Accounts Production can import year-end trial balances from Xero, QuickBooks, or FreeAgent and export journals and adjustments; integrations differ between products. TaxCalc supports self-employment and investment income, but does not include state filing. It runs on Linux, macOS, and Windows, with mobile access limited to the web. Pricing is paid, from £42, with a free trial and no free plan. TaxCalc says each licence includes unlimited weekday phone and email support from UK-based, accountancy-trained specialists.
