EAS EU & UK Compliance vs Tax Rex ‑ Sales Tax Automationfor Shopify (2026)

EAS EU & UK Compliance and Tax Rex – Sales Tax Automation are both Shopify apps in the Finances and Taxes categories, but they address distinct geographical markets and compliance needs. EAS EU & UK Compliance focuses on enabling merchants to sell into the European Union and the United Kingdom by automating compliance with regulations like IOSS, OSS, UK VAT, GPSR, and EUDR. It offers features like IOSS registration, automated tax reports, and acting as an Authorized Representative for GPSR. Tax Rex, on the other hand, is designed for US merchants and focuses on simplifying US state sales tax compliance, including accurate tax reports, timely filing, economic nexus alerts, and state registration assistance. The primary difference lies in their target regions. EAS is for merchants expanding into Europe, while Tax Rex is for those focused on the United States. EAS offers services like currency conversion and acts as an authorized representative, pointing to a broader service offering that extends beyond just tax reporting. Tax Rex emphasizes ease of use and time savings for US-based sales tax, highlighting its automated filing capabilities and economic nexus alerts. Both apps have high ratings, but Tax Rex has a slightly higher rating and a greater number of reviews, suggesting broader adoption within its target market. However, review volume alone doesn't tell the whole story; the importance of the features will depend on the merchants' specific needs.
