## About

VAT calculation and compliance infrastructure for Europe

VAT Engine helps SaaS and e-commerce businesses calculate, record, and review EU VAT without building complex tax infrastructure internally.

Use a developer-friendly API to:

- retrieve current and historical VAT rates for all 27 EU member states

- calculate net, gross, and VAT amounts

- apply merchant-friendly product tax classes

- preserve transaction-level calculation evidence

- organize stores, marketplaces, and other sales sources

- monitor cross-border thresholds

- prepare data for OSS and IOSS reporting workflows

VAT Engine uses official EU TEDB rate data and adds a practical merchant-facing layer for product classification, historical calculations, and compliance workflows.

The platform is currently in alpha and is free for early users. Feedback from developers, SaaS founders, e-commerce businesses, and tax professionals is welcome.
