Cabinet Decision No. 39 of 2019, Article 67, specifies the approved methods for communication between the Authority and taxpayers. Official notifications from the Authority can be delivered via direct hand delivery, registered mail, or approved electronic means (email and apps) that provide receipt confirmation. Conversely, taxpayers can submit information to the Authority via registered mail, hand delivery, or electronic systems. This formalizes digital communication as a legally recognized method, ensuring that both parties have multiple secure channels for the exchange of documents and notifications.
