Taxstream ProVision is an end-to-end system for producing quarterly and annual tax provisions without maintaining a corresponding spreadsheet. It guides data collection, provision calculations, and footnote production. The footnote generator connects to the tax database and updates reports when provision data changes, while ProTrace traces calculations between the general ledger and footnote. An automated audit trail records each provision step, and Review Mode lets auditors and advisors examine the work. Listed tax functions include foreign tax credit calculations, customized grouping, uncertain tax positions, and roll-forwards that retain calculations, rates, reports, and dashboards. The Model workspace develops and evaluates strategies against the global effective tax rate, imports spreadsheet or compliance-system data, and supports AI-based forecasting and scenario planning. EntityChart maps entity relationships and stores tax information. A.T.O.M. can select and apply plays from an integrated tax-planning playbook. Pricing is on request.
