Hungary Publishes ViDA Implementation Document, Signalling Major VAT Reform

Hungary has published its ViDA implementation plan, signaling a major VAT reform that will introduce mandatory e-invoicing and real-time data exchange between businesses and tax authorities for both domestic and cross-border transactions. The reform also includes new buyer reporting obligations (AOR), standardized EN 16931 invoicing, and a shift away from email-based invoicing toward a secure, tax authority–integrated system.

At the beginning of March, the Hungarian National Tax and Customs Office (NAV), in cooperation with the Ministry for National Economy, released a document outlining how Hungary plans to implement the EU’s VAT in the Digital Age (ViDA) initiative.

The document highlights a fundamental transformation of the country’s VAT system, particularly in the area of mandatory e-invoicing.

Shift to Real-Time Data Exchange

Under ViDA, invoicing will move from a static, record-keeping function to a real-time data exchange system between businesses and tax authorities. This means invoice data will be transmitted continuously, allowing authorities to monitor transactions almost immediately.

Mandatory e-invoicing will apply to both domestic and cross-border transactions, covering accounts receivable and payable.

New Buyer Reporting Obligation

Hungary also plans to introduce a new requirement for buyers, known as AOR (Accounts of Receivable reporting). Buyers will need to report data on received invoices within five days, adding an extra layer of transparency.

Standardization and Technical Changes

All e-invoices must comply with the EN 16931 European standard, ensuring harmonization across the EU. Additionally, due to secure transmission channels with built-in authentication and encryption, email-based invoice exchange will no longer be allowed.

The system will follow a five-corner model, where invoices are exchanged via tax authorities, with optional involvement of accredited service providers.

Looking Ahead

Although the document sets the direction, it does not yet provide a detailed implementation timeline or technical specifications. However, it clearly signals that ViDA will have a transformative impact on Hungary’s VAT system, with further guidance expected in upcoming publications.
