ONESOURCE Determination
ONESOURCE Determination automates calculations for sales tax, use tax, GST, VAT, and excise tax. The web-based product connects with ERP, financial, billing, e-commerce, point-of-sale, and payment systems through pre-built or custom integrations. It supplies global tax rates, rules, and calculations in real time, with cloud synchronization to support high transaction volumes. Deployment includes a cloud-based indirect-tax engine and an edge-computing option. Determination Anywhere supports business-specific security and data-residency requirements. Tax content covers specialized jurisdictions and industries, with industry offerings for oil and gas, retail, manufacturing, and technology. Configuration features include company structures, global calculations, and tax-return streamlining. Thomson Reuters says its automated calculations and certified processes aim to reduce audit-triggering mistakes; the processes are backed by SSAE 18 and ISAE 3402 certifications.
