How do I configure Moms 25% in Magento, and the B2B reverse-charge?

Denmark has the highest standard VAT in the EU, flat 25% Moms on virtually everything. There’s no reduced rate for food, books, or newspapers (unlike most EU countries), just a 0% rate on exports and a few tightly-defined exemptions (financial services, healthcare).

Magento configuration:

1. Create a single Moms 25% tax rate scoped to Denmark (or destination-based for EU shipping).
2. Create a Moms 0% rate for: (a) exports outside the EU, (b) intra-EU B2B sales with valid VIES-validated VAT number (reverse-charge, the buyer accounts for VAT in their country).
3. Assign products to the standard tax class, all goods get 25%.
4. For B2B reverse-charge: customer must have a valid vat_id validated against VIES (CVR for DK customers, equivalent EU VAT number for others). If valid + cross-border + B2B, apply 0% with the legal text “Reverse charge, Customer to account for VAT” on the invoice (also required in Danish: “Omvendt betalingspligt”).
5. For B2C shoppers in other EU countries, apply the destination country’s VAT (OSS / One Stop Shop rules since 2021 if you’re over the €10k threshold).

Storefront shows tax-inclusive prices (mandatory in EU B2C); tax-exclusive on B2B if explicitly opted-in.
