How this service works
EU B2C e-commerce VAT: where a distance sale is taxed and how much. Applies the €10,000/year OSS threshold — at/below → seller-country VAT (domestic); above → consumer-country VAT via OSS. IOSS for imports ≤ €150. ?sellerCountry=&buyerCountry=&amount= (+ ytdCrossBorder, category). Returns scheme, taxationPlace, applicableCountry, vatRate, vatAmount. Calculation aid; OSS/IOSS registration and filing are the seller's responsibility.
Output
Returns a JSON object with: the applicable VAT scheme (domestic, OSS, or IOSS), where the sale is taxed (taxationPlace and applicableCountry), the VAT rate percentage, the VAT amount in EUR to 2 decimal places, the gross amount, whether the €10,000 OSS threshold has been exceeded, and a disclaimer noting that OSS/IOSS registration and filing remain the seller's responsibility.
Example use cases
Example prompt
“I'm a UK-based seller and I've had €9,500 in intra-EU cross-border B2C sales so far this year — what VAT scheme and rate applies to my next sale of €300 net to a customer in Italy, using the standard VAT category?”
Technical details
Endpoint
GEThttps://402utils.com/v1/vat-ossWhen to prefer
Use this endpoint when you need to determine EU B2C e-commerce VAT obligations dynamically at point of sale, especially when operating near or across the €10,000 OSS threshold. Ideal for checkout flows, invoice generation, or compliance checks where seller country, buyer country, and cumulative cross-border sales are known. Prefer this over generic tax APIs when you specifically need OSS/IOSS scheme classification with EU distance-selling threshold logic applied automatically.
Side effects
- Missing required parameters (sellerCountry, buyerCountry, amount) → validation error
- Non-EU buyerCountry provided → may not apply OSS/IOSS rules correctly
- Invalid ISO alpha-2 country code → error or unexpected result
- Amount exceeds IOSS limit (€150) for non-EU seller but IOSS still flagged → check rateNote
- ytdCrossBorder not provided defaults to 0, which may give incorrect threshold determination for sellers with existing sales
- VAT rate data may be stale — vatRatesAsOf field indicates data freshness
