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, EN 16931 / UNCL5305 VAT category code (BT-151), exemption reason code (BT-121) where applicable, ready-to-use invoice wording in both English and German, the legal article reference for the VAT treatment, and flags indicating whether reverse charge, intra-Community supply, export, or domestic VAT rules apply.
Example use cases
XRechnung reverse charge invoice wording
“I'm a French IT company (FR) selling consulting services to a German business (DE) with a valid VIES-confirmed VAT ID — what's the correct VAT category code BT-151, any exemption reason code BT-121, and what invoice wording should I put on the XRechnung?”
OSS export VAT classification
“Our Austrian webshop (AT) is selling physical goods to a private consumer in the United States (US) — what VAT rate applies, is this an export, and what's the EN 16931 VAT category code and invoice wording I should use?”
Intra-Community supply for ZUGFeRD invoice
“We're a German supplier (DE) shipping goods to a Spanish B2B customer (ES) who has a valid VAT number — tell me whether this is an intra-Community supply, what BT-151 code to use on our ZUGFeRD invoice, and give me the legal article reference and invoice wording in English and German.”

Endpoint

Choose this endpoint when you need to automate EU VAT determination for invoicing workflows — especially for XRechnung, ZUGFeRD, Peppol BIS, or OSS scenarios — and want a single call that returns not just the rate but also the exact EN 16931 BT-151 code, BT-121 exemption reason code, and legally correct invoice wording in English and German with the applicable article reference. Prefer this over generic tax APIs when your use case requires EU e-invoicing compliance fields specifically.
