VAT-registered companies will have to exchange invoices through the Peppol network under new rules aimed at improving tax compliance.

Businesses in Slovakia will face a new legal obligation from next year. PDF invoices sent by email will no longer be accepted for business-to-business transactions. Instead, they will be replaced by electronic invoices transmitted via the Peppol network.

The change will be mandatory for all VAT-registered businesses, which will be required to issue invoices in XML format.

One of the main aims of the reform is to strengthen tax compliance.

“The Financial Administration will have access to invoice data almost in real time, enabling more effective monitoring and fraud detection,” consulting firm PwC says in its guide to e-invoicing.
