‘DAC7’ (Directive on Administrative Cooperation 7), introduces new requirements for online platforms, obliging them to report data about their users' transactions to the tax authorities. The law will enter into force on 1 January 2023. DAC7 aims to harmonise reporting obligations throughout the EU, specifically as regards online platforms. It also governs the sharing of that information among tax authorities. Under DAC7, the provider of an online platform that allows sellers to be connected to other users for the purpose of carrying out a "relevant activity" must start collecting transaction and other data regarding those users. Sellers can be both entities and natural persons. If the seller is a natural person and qualifies as a reportable seller, certain personal data will have to be collected and reported, as further specified in DAC7. Relevant activities are: The rental of immovable property, including both residential and commercial property, as well as any other immovable property and parking spaces; Personal service; The sale of goods; and The rental of any mode of transport. Under the new law, the data collected by the platform must be reported to the national Tax and Customs Administration, subject to certain exceptions. For instance, a seller is not reportable if it has concluded less than 30 relevant activities and the total revenue in relation to these activities is below EUR 2,000 in any year. With other words, the days of selling watches anonymously are over. Big brother is watching you... : ) Any comments?
