Calculate EU VAT (Dutch: BTW) for a cross-border or domestic sale, using
the destination-country principle that applies to e-commerce.
Handles the cases sellers get wrong: OSS distance selling to another EU
country, B2B reverse charge when the buyer has a VIES-valid VAT number,
and zero-rated exports outside the EU. Rates are the statutory ones for
the destination country, including reduced rates when a category is given.
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| amount | number | yes | Net amount (excluding VAT) in euros. |
| customer_country | string | yes | Two-letter country code the goods are shipped to, e.g. NL, DE, FR. This is what determines the rate. |
| seller_country | string | no | Two-letter country code the seller is established in. Defaults to NL. |
| customer_vat_number | string | no | Buyer VAT number. Required for B2B reverse charge; it is checked against VIES, so an invented number will not zero the VAT. |
| is_business | boolean | no | True when the buyer is a business (B2B). Reverse charge also needs a valid VAT number. |
| category | string | no | Optional product category, used to find a reduced rate (books, food, medicine and similar). |
