In short

Under the PStTG, reporting platform operators must identify their sellers, collect and verify their tax data, and transmit the reportable income electronically to the Federal Central Tax Office (BZSt) annually by 31 January. Sellers receive a copy of their data.

Who is a reporting platform operator?

Reportable are operators of digital platforms that connect sellers and users so that relevant activities are performed for consideration — such as the sale of goods or personal services. The PStTG definition governs; classifying an individual case can be demanding.

What duties apply specifically?

Core duties of reporting platform operators under PStTG.

By when must they report?

Reporting covers the past calendar year and must reach the BZSt by 31 January of the following year. Transmission is electronic via the BZSt DAC7/DPI data interface following the prescribed schema.

What happens in case of breaches?

Breaches — such as a report not filed, filed late or incomplete — can be punished as an administrative offence with a fine. Operators should therefore document their due-diligence and reporting processes cleanly. The current BZSt specifications govern the actual assessment.
