How do you register for the VAT OSS Scheme and declare VAT?
Registration for the OSS Scheme can be done through each EU state's online portal dedicated to the One-Stop shop. In Estonia, it’s done via the Estonian Tax and Customs Board’s self-service portal. VAT declarations under the OSS Scheme must be made every quarter. This process involves logging in with your local ID or Estonian e-residency card, navigating to the “OSS/IOSS” registration section, and filling in the required information.
