From 2027, the Slovak Tax authority will require<\/a> all VAT-registered companies based in Slovakia to send and receive structured invoices digitally for domestic B2B and B2G transactions. To transmit the invoice data, companies must use a certified service provider<\/a>, such as Retarus.<\/p>\n\n A new development in Slovakia is that in addition to transmitting the actual invoice to the recipient, a special report now needs to be submitted to the Slovak tax authorities concurrently. The certified service provider is also responsible for handling this submission. However, the existing reporting methods will still be permitted in parallel until 2030 to smooth the transition.<\/p>\n\n Slovakia is thus set to become the first country in Europe to extend the tried-and-tested Peppol 4-corner model into a 5-corner model. Peppol (short for Pan-European Public Procurement On-Line) is an international network for exchanging structured documents in the course of supply chain processes. A large number of countries have adopted the network as a technical platform for exchanging invoices in compliance with EN 16931.<\/p>\n\n According to the standard 4-corner model, the invoice is transmitted from the sender (1) via their Peppol service provider (2) to the recipient\u2019s Peppol provider (3) and finally forwarded to the recipient (4). In the 5-corner model, however, the certified service provider is additionally required to transmit a \u201ctax data document (TDD)\u201d to the tax authority (5) in near real time. The TDD exclusively contains information which is strictly relevant to the tax authority.<\/p>\n\nSlovakia to introduce the Peppol 5-corner model<\/h2>\n\n
