E-invoicing requirements in Hungary

Legal obligations

The central, regional and local contracting authorities in Hungary are ready to receive and process e-invoices.

There are no legal obligations, but all B2B and B2C transactions must be reported real-time to the Hungarian authorities, regardless off their amount. This applies to all businesses registered in Hungary for VAT purposes - including non-resident ones - and for transactions that have Hungary as place of supply.

Options for sending e-invoices to Hungary

The Hungarian National Tax and Customs Administration (NAV) has established the central platform Online Invoicing System (OSA) to enable real-time eInvoice reporting. All taxpayers must use OSA to send their e-invoices to the government.

There are no requirements for e-invoice formats in Hungary. You can use any type, from Peppol to email or PDF.

A platform like Billit is an official Peppol Access Point and connects directly to the Hungarian Online Invoice System (OSA). This means you can safely send your e-invoices to the Hungarian government and to your customers. You can also receive e-invoices in the same platform.

Registering on the Peppol network and sending your first e-invoice only takes a few minutes.
