Reporting obligation regarding digital platforms to be standardised in EU countries – Changes to annual information returns

New standardised rules on the reporting obligation regarding sales carried out through digital apps and platforms will enter into force on 1 January 2023 in EU countries. The rules are an extension to today’s reporting that so far only concerns transportation and rental services. After the new rules have come into force, many other services facilitated through digital platforms will be included in the information-reporting requirement (IRR). Platform operators - companies that offer a digital platform for providing services and selling goods - have the reporting obligation to tax authorities.
New standards will be introduced regarding the data content and technical format of annual information returns. The Tax Administration will specify the exact requirements later in 2022.
