United Kingdom: UK VAT IOSS Import Scheme: Service Availability and Issues

Released 1 September 2026, this guidance details service availability and known issues for the VAT Import One Stop Shop (IOSS) Scheme, which allows UK and non-EU businesses to collect, declare, and pay VAT on distance sales of low-value goods (≤€150) imported into the EU. Following the UK’s departure, UK sellers shipping directly to EU consumers must register for IOSS via an EU intermediary or use the HMRC-managed portal for Northern Ireland movements. The page tracks portal uptime, API response times, and data synchronization delays with EU tax authorities.

Key Takeaways

  • IOSS Portal Stability Directly Impacts Customs Clearance: Goods entering the EU under IOSS require a valid IOSS number at customs declaration. System downtime can cause border holds, VAT overpayment, or customer delivery failures. HMRC’s status page is the authoritative source for UK-registered intermediaries to verify operational readiness before peak trading periods (e.g., Black Friday, Christmas).
  • Data Integrity and Reconciliation Requirements: The guidance highlights recurring issues with mismatched transaction IDs between seller platforms and the IOSS portal, leading to duplicate VAT assessments. Businesses must implement automated reconciliation routines and retain digital evidence of IOSS declarations for a minimum of 10 years per EU retention rules.
