Overview
ONESOURCE is Thomson Reuters' enterprise tax platform covering indirect tax determination, compliance and reporting, and e-invoicing. Its Determination module automates real-time calculation of VAT, GST and sales and use tax for both AR and AP transactions by applying country-, product- and customer-specific rules, while its Compliance module handles return preparation, filing and statutory reporting.
The platform integrates the Pagero global e-invoicing network (acquired by Thomson Reuters in 2024) as ONESOURCE Pagero, enabling end-to-end exchange of compliant e-invoices and business documents and connectivity to government tax platforms worldwide. ONESOURCE continuously prepares VAT returns, SAF-T/SII filings and listings while reconciling data across ERP systems, e-invoicing platforms and tax authorities.
Thomson Reuters is a publicly traded information and software company, and ONESOURCE is positioned for multinationals and large enterprises requiring globally consistent indirect tax determination, statutory compliance and e-invoicing on a single suite.
