Since 1 July 2021, the second stage of the so-called VAT digital package of the EU Commission applies. Linked to this is the introduction of the One-Stop-Shop, or OSS.
The reporting and payment of tax liability in other EU countries for merchants based in Germany is carried out via the BZSt online portal (BOP).
We describe step by step how the OSS reporting works.
