OSS / IOSS
EU VAT single windows for cross-border e-commerce.
Definition
OSS covers intra-EU distance sales of goods and certain B2C services; IOSS covers imports of goods with an intrinsic value ≤ €150. The seller registers in a single Member State, obtains an IOSS identification number and files one return instead of registering in every country of consumption. The IOSS number is passed to customs to relieve import VAT.
Origin
Introduced by the VAT e-commerce package: Council Directive (EU) 2017/2455 and Council Directive (EU) 2019/1995, applicable since 1 July 2021.
Example in context
IOSS number of the form IMxxxyyyyyyz (IM + 3-digit country code + 7 digits), supplied to the carrier for the H7 customs declaration.
