How does 25% Moms work, any tricks for tax categories?

Sweden has one of the world’s highest standard VAT rates at 25%, you set this as your default Magento tax_class rate. But three reduced rates apply:

• 12% Moms, food, restaurants, hotels.
• 6% Moms, books, newspapers, magazines, public transport, cultural events.
• 0% Moms, healthcare, education, financial services.

Tricks:

1. Use Magento tax_class_product per category (e.g. fashion = 25%, books = 6%).
2. OSS for cross-border B2C to other EU countries, one VAT registration, you collect destination-country VAT.
3. Reverse charge for B2B to other EU countries (zero-rated, with VAT-number / org-no validation via VIES + Skatteverket).
4. SEK pricing displayed inclusive (Sweden expects inclusive retail prices, exclusive only for B2B).
