E-invoicing Iceland: Everything you need to know

Understand Iceland's e-invoicing mandates, formats, and compliance requirements for businesses and freelancers.

E-invoicing has been mandatory for public sector transactions in Iceland since 2015, marking a significant step toward digitalization. More recently, Iceland has aligned with broader European standards through its adoption of the Peppol network, facilitating structured invoice exchange both domestically and cross-border. These developments reflect Iceland’s commitment to increasing efficiency, transparency, and interoperability in fiscal processes.

 

In this framework, B2Brouter operates as an authorized Peppol Access Point, enabling businesses and freelancers to comply with Icelandic regulations and send invoices in approved formats. The system ensures legal validity, secure delivery, and compliance with national standards set by the Ministry of Finance and Economic Affairs.

 

As Iceland continues its digital transformation, understanding current e-invoicing obligations and upcoming changes is essential. In the next sections, we will outline the most relevant dates, key legislation, and how to prepare your invoicing process to stay compliant in the Icelandic market.
