Author : Lily Joseph | Published On : 24 Feb 2026

Selling to EU customers in 2026 requires more than competitive pricing — it demands proper IOSS (Import One-Stop Shop) compliance. This guide explains what IOSS is, who needs to register, and why it’s essential for UK and non-EU e-commerce businesses shipping goods under €150 to EU consumers.

The blog covers the IOSS registration process, the mandatory EU intermediary requirement for non-EU sellers, monthly VAT return obligations, payment timelines, VAT rate differences across 27 EU member states, customs documentation requirements, and 10-year record-keeping rules.

It also highlights common compliance risks, the strategic benefits of collecting VAT at checkout, and how proper IOSS management improves customer experience, reduces delivery delays, and prevents unexpected import charges.

A must-read for e-commerce sellers, accountants, and online retailers expanding into EU markets.
