The governing body of the Turkish tax system is known as the Gelir Idaresi Baskanligi, or GIB. That organization is also responsible for the sending, receiving and storing of e-invoices for ten years, another departure from standard operating procedures of other nations. Under Turkish law, senders and recipients of electronic invoices do not transmit them directly to one another. Instead, those who wish to issue invoices electronically must register with the Turkish Revenue Administration (TRA) or the GIB. Every e-invoice issuer automatically becomes capable of being a recipient, as well, meaning they must accept electronic invoices sent by any other registered user.
In contrast with the European system, where senders and recipients of electronic invoices send the bills directly to one another, the government is involved in Turkey. In that nation, the TRA acts as the system hub, so that issuers send their e-invoices to the TRA, who then forwards them to the correct recipient via the web. So that e-invoices are uniform, the Turkish government has created an XML format for the documents.
To ensure the authenticity of e-invoices, the use of electronic signatures is required by law. As such, a Financial Seal or an electronic certificate issued by The Scientific and Technological Research Council of Turkey must be adhered to the document.
In order to serve as an e-billing service, a business must be approved by the Turkish government. In order to gain that authority, the business must meet several criterions. For example, the entity must possess a registered Turkish company name and maintain its main DPC in that nation.
