How this service works
EU VAT decision engine for invoicing and e-invoicing: determines place of supply, reverse charge, intra-Community supply, export or domestic VAT, returns the rate and the EN 16931 / UNCL5305 VAT category code (BT-151) plus exemption reason code (BT-121) and ready-to-use invoice wording (EN/DE) with the legal article reference. For XRechnung, ZUGFeRD, Peppol BIS and OSS workflows.
Output
Returns the applicable VAT rate for the transaction, the EN 16931 / UNCL5305 VAT category code (BT-151), the exemption reason code (BT-121) where applicable, a ready-to-use invoice statement in both English and German, the relevant legal article reference, and the determined VAT treatment type (e.g. reverse charge, intra-Community supply, OSS, export zero-rate, or domestic).
Example use cases
Reverse charge check for B2B services
“My Spanish company is invoicing a French VAT-registered business for consulting services — does reverse charge apply, and what EN 16931 VAT category code and invoice text should I put on the ZUGFeRD invoice?”
OSS eligibility for B2C digital goods
“We're a German online retailer selling digital goods to Italian consumers (B2C). Does the OSS scheme apply, what VAT rate should we charge, and what's the correct BT-151 code for the Peppol BIS invoice?”
Export VAT treatment outside EU
“Our Dutch company is exporting physical goods to a US customer — is VAT zero-rated, what's the EN 16931 exemption reason code BT-121, and what legal article reference and invoice wording should we use in English?”

Endpoint
GEThttps://api.eucompliance.tools/x402/vat-rules?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically determine the correct EU VAT treatment, EN 16931-compliant codes, and ready-to-use invoice wording for XRechnung, ZUGFeRD, Peppol BIS, or OSS workflows — especially for cross-border B2B and B2C transactions involving EU suppliers. Prefer it over manual lookup when automating invoice generation pipelines or when you need both the machine-readable VAT category codes and the legally compliant human-readable wording in one call.
