The Import One-Stop Shop (IOSS) is the electronic portal businesses can use from 1 July 2021 to comply with their VAT e-commerce obligations on distance sales of imported goods.
According to the VAT rules applicable up until 1 July 2021, no import VAT has to be paid for commercial goods of a value up to EUR 22.
The new VAT e-commerce rules will abolish this provision as of 1 July 2021. Thus, from 1 July 2021, all commercial goods imported into the EU from a third country or third territory will be subject to VAT irrespective of their value.
