The role
What is an IOSS intermediary?
An IOSS intermediary represents a retailer under the Import One-Stop Shop scheme. It supports registration, monthly VAT reporting and payment to the relevant tax authority on the retailer’s behalf.
Register
The intermediary registers the retailer and obtains the IOSS identification number for eligible consignments.
Report
It submits monthly IOSS VAT returns using the retailer’s reconciled sales and adjustment data.
Pay
It pays the VAT due to the relevant authority and supports the records required by the scheme.
UK businesses
Do UK retailers need an IOSS intermediary?
It depends on where the legal entity is established. Great Britain and Northern Ireland follow different registration routes.
Important: IOSS is optional and applies only to eligible low-value B2C consignments. It does not cover excise goods or consignments above the scheme threshold.

Asendia is not an IOSS intermediary. Asendia can recommend a potential intermediary and facilitate the first contact. Appointment, onboarding, commercial terms and the ongoing VAT relationship are agreed directly between your business and the intermediary.
IOSS must work alongside checkout, customs data and delivery. Explore Asendia’s customs clearance solutions and international parcel delivery services.
