Slovakia adopts Peppol network for decentralized e-invoicing system.

Slovakia’s Financial Administration will serve as the national Peppol Authority, introducing a decentralized e-invoicing system based on the Peppol network, with legislation expected by summer 2025. Mandatory B2B e-invoicing and real-time reporting to tax authorities will begin in January 2027. The system enables structured invoice exchange via certified providers without buyer pre-approval, ensuring flexibility and compliance through a five-corner model.

 

The Financial Administration will become the Slovak Peppol Authority, facilitating a five-corner model for e-invoicing and e-reporting, with a draft law expected by summer 2025. As a reminder, mandatory e-invoicing starting January 2027 is introduced for B2B domestic transactions and real-time reporting to tax authorities.

Slovakia’s Financial Administration (FS) has introduced plans to implement a decentralized e-invoicing system through the Peppol network, marking a major step toward mandatory nationwide digital invoicing.

Peppol Network Integration will mean that businesses will exchange structured e-invoices without requiring prior buyer consent, as all companies will be registered in the network.

Companies will use certified service providers to handle invoice validation, submission, and compliance, ensuring flexibility and local support, which means that a decentralized approach is accepted.
