Hungary’s National Tax and Customs Administration (NAV) has published a concept document outlining how the country may implement the EU’s VAT in the Digital Age (ViDA) initiative. Although the material is not yet a finalized legal framework, it provides early insight into how Hungary’s invoicing and VAT reporting landscape could evolve in the coming years.
The proposed model represents a major shift from traditional invoice documentation toward data-driven digital reporting, where invoice data becomes a central element of communication between businesses and tax authorities.
Key elements of the proposed framework include:
-
Mandatory e-invoicing for domestic B2B transactions and transactions between Hungarian and EU businesses
-
Structured invoices based on the EN 16931 European standard, requiring invoices to be issued in machine-readable XML format
-
XML as the legally binding invoice, with any PDF or visual version serving only as a representation of the structured data
-
Secure transmission channels and pre-validation controls within invoicing software to prevent issuance of incorrect invoices
-
Potential accreditation requirements for invoicing software and service providers to ensure technical compliance
-
Buyer-side reporting obligations, where buyers may need to confirm receipt of invoices and provide status information to the tax authority
-
Possible integration with the Peppol network, although its use would remain optional rather than mandatory
The concept also highlights the potential introduction of additional services by the tax authority, including invoice archiving, transmission services, and conversion tools to support the transition from the current system to the new structured format.
While further consultation and regulatory clarification are expected, the document indicates that Hungary is preparing for a significant digital transformation of its VAT compliance framework, aligning its future system with broader EU digital VAT reforms.
