Online Számla or Online Invoice is the system set up by the Hungarian Tax and Customs Administration in order to receive and process invoices sent by taxpayers.
In Hungary, cash registers sending transaction data to the authorities are mandatory in retail for years now.
But, in case of invoice issuance, the real-time reporting obligation of the invoice data is another requirement.
The final start dates of the e-invoicing obligation were July 1st 2020 for B2B and January 4th 2021 for B2C transactions (with a grace period until April 1st 2021).
