About

Vatstack is a VAT API providing tax tools before and after a payment, aimed at businesses selling telecommunications, broadcasting, and electronic services internationally. Its rates API covers domestic and cross-border sales and updates rates when government changes take effect. The service can calculate VAT-inclusive or VAT-exclusive prices, determine customer location from an IP address or billing address, validate VAT numbers for exemption, and adjust rates for some digital products such as ebooks. Real-time VAT and GST checks cover the 27 EU member states, Australia, Norway, Singapore, Switzerland, and the United Kingdom. EU and UK checks include a consultation number, and validation records are stored in the cloud and replicated between EU data centers on AWS. Bulk validation is available through CSV import in the dashboard. Vatstack compiles VAT OSS and EC Sales List reports using European Central Bank exchange rates, and its Stripe integration syncs invoices, location evidence, and tax IDs and adjusts reports after refunds. The Developer plan is free for dummy validations and supplies; paid plans start at $15.00 USD per month.
