What it is
ONESOURCE Determination is a web-based product from Thomson Reuters that automates calculations for sales tax, use tax, GST, VAT, and excise tax. It connects with ERP, financial, billing, e-commerce, point-of-sale, and payment systems using pre-built or custom integrations. The product delivers global tax rates, rules, and calculations in real time, and supports high transaction volumes through synchronization with its cloud tax engine. Deployment includes a cloud-based indirect-tax engine with an edge-computing option. Determination Anywhere supports business-specific security and data-residency requirements. Its global tax content covers specialized jurisdictions and industries, with industry offerings for oil and gas, retail, manufacturing, and technology. Configuration features cover company structures, global calculations, and tax-return streamlining. Thomson Reuters says automated calculations and certified processes aim to reduce audit-triggering mistakes; those processes are backed by SSAE 18 and ISAE 3402 certifications. Pricing is available on request, and a free demo can be requested. The listed pricing page reports that it cannot find the page, so no fixed price is provided here.
