The Import One-Stop Shop (IOSS) is the electronic portal businesses can use from 1st July 2021 to comply with their VAT e-commerce obligations on distance sales of imported goods. IOSS only relates to the distance sales of imported goods with a consignment value of less than EUR150.
If the sale of the goods is made through a marketplace, the marketplace is considered to have made the sale and is therefore liable for any VAT owed. IOSS is designed to allow suppliers and marketplaces selling imported goods to EU consumers to collect and pay the VAT to the relevant tax authorities, instead of the buyer paying the VAT at the point of import.
