What is IOSS and do I need to register?

IOSS (Import One-Stop Shop) is an EU scheme simplifying VAT collection for goods ≤€150 shipped from outside the EU. You register in one EU member state, collect VAT at checkout, and remit through the IOSS portal. Shipments get 'green channel' customs treatment, faster clearance, no delivery charges. In 2026, IOSS is the standard for EU-bound sellers. Swap automates IOSS VAT collection as part of its compliance engine.
