International tax (VAT / GST / sales tax), handled differently?
Compare the tax configuration and provider services available for your selling regions, products and business registrations. Calculation, invoicing, filing and remittance are separate tasks; the included service and eligibility can vary. Have a tax professional confirm the setup your business requires, then test representative addresses, exemptions, shipping, refunds and displayed prices. Shopify and Magento offer tax configuration, but choosing either platform does not by itself settle every VAT, GST or sales-tax requirement.
