Hori Global Tax API review
A low-cost tax API for global calculations, validation and selected XML workflows.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
Hori Global Tax API provides tax-rate, threshold and validation data through an API for businesses building tax compliance into software. It is suited to developers and organizations that need worldwide sales-tax calculation, US coverage across all 50 states, VAT support for the EU and UK, and Australian ABN validation. The service is cloud-based and available through web and API access, with plans designed for small, mid-market and enterprise organizations.
Pricing is based on monthly request volume. Starter costs £5.99 per month for 50 requests, while Scale costs £25 per month for 2,500 requests, Essential costs £50 per month for 7,000 requests and Premium costs £500 per month for 80,000 requests. Annual options are £57.5, £240, £480 and £4,800 per year for those same plans and request limits. The core plan highlights remain consistent across tiers, so the main practical difference is capacity. That makes Starter a low-cost entry point for limited workloads, while higher-volume applications need to assess which request allowance fits their traffic.
Its strongest area is the combination of calculation, validation and preparation features. Invoice OCR supports e-invoicing workflows, while UK MTD XML and Spanish SII XML generation can prepare files for submission through tax-authority websites. Integrations include Microsoft Dynamics 365, SAP S/4HANA, Oracle NetSuite, Sage, Exact, VISMA and other ERP and accounting systems. Email support and documentation are available. Hori Global Tax API is a good fit when a product needs tax data and compliance preparation inside its own software. Organizations seeking automated return filing or registration support should choose a more end-to-end compliance service.
