Post-Brexit e-commerce: Simplifying EU Sales with IOSS

A comprehensive guide for non-EU sellers: Reclaiming the European market through automated IOSS and GPSR compliance in 2026.

Brexit has brought significant changes to e-commerce in Europe, particularly for businesses selling to the EU. One solution to simplify EU sales post-Brexit is the introduction of the IOSS (Import One-Stop Shop) system. For businesses, navigating the complexities of EU sales after Brexit can be daunting; however, the IOSS system aims to streamline the process and make it more efficient.

By using the IOSS, businesses can declare and pay VAT (Value Added Tax) on sales made to EU customers in a single VAT return, reducing the administrative burden associated with multiple VAT registrations in different EU member states. This is particularly beneficial for small and medium-sized e-commerce businesses that may not have the resources or expertise to navigate the complexities of VAT compliance in multiple EU countries.

Simplifying EU sales with the IOSS system is a crucial step towards facilitating cross-border e-commerce post-Brexit. By adopting the IOSS, businesses can streamline their operations, reduce administrative costs, and enhance the overall customer experience when selling to the EU market.

The Impact of Brexit on UK-EU E-commerce

Post-Brexit regulatory divergence has markedly constricted UK-EU e-commerce, imposing additional customs duties, customs handling fees and VAT compliance burdens on export to EU. Confronted with new rules and logistical hurdles and increased operational costs post-Brexit, a significant number of UK businesses have found themselves compelled to reassess their European market strategies, often choosing to withdraw altogether.

Yet, to forsake the EU’s vast e-commerce market – a behemoth with over 450 million consumers – is unequivocally a lost opportunity for UK e-commerce. Withdrawing from the EU Single Market translates to not just higher tariffs but also intricate customs procedures, stymieing UK-based vendors.

GPSR: The New Compliance Standard for 2026

In 2026, IOSS is only half the battle. To legally sell consumer products into the EU, UK and international sellers must now comply with the General Product Safety Regulation (GPSR). This requires every non-EU merchant to appoint an EU-based Authorised Representative. EAS offers full GPSR compliance services, ensuring your products aren’t blocked from marketplaces or seized at customs. This is now a significant part of doing business within the EU.

The Barrier of Post-Brexit VAT Regulations without IOSS

Brexit announced changes in VAT obligations, ensnaring UK traders in a web of tax complexities. Navigating post-Brexit VAT without IOSS means dealing with each EU member state’s unique rules—an administrative and financial quagmire. Currently, import VAT applies upon entry to each individual EU country for shipments over 150€, with varied obligations creating daunting barriers. For shipments under 150€, IOSS remains the most recommended route to avoid these hurdles.

The EU as a Vital Market for UK Businesses

Despite the separation hurdles, the European Union remains a cornerstone for UK e-commerce entities eager to tap into its sizable and affluent consumer base. With 27 member countries, a collective population surpassing 440 million, and a GDP ranking among the highest globally, the EU market is teeming with potential for UK businesses. The region’s economic resilience positions it as a crucial commercial partner for achieving substantial international expansion and revenue diversification.
