E-Invoicing in Hungary for B2G and B2B transactions is not mandatory. However, all companies are required to undertake real-time invoice reporting (RTIR). In the RTIR model, electronic invoicing in Hungary is not strictly regulated but permitted. Even so, the vendor must report the subset of the invoice to the tax agency in a predetermined format shortly after it is issued and handed over to the buyer.
Since 1 April 2021, it has been obligatory to disclose data on all invoices in Hungary, as well as modification and invalidation invoices to which the invoicing rules of the Act on VAT apply.The data disclosure must be fulfilled via the Online Invoice System (Számla platform). This also applies to business-to-customer (B2C) transactions, and transactions issued by non-residents.

The Hungarian fiscal system operates within the framework of the tax authority, Nemzeti Adó és Vámhivatal, known as NAV. This office, prior to the introduction of the electronic invoicing system, introduced the electronic reporting system RTIR. Immediately after issuing an invoice, its details should be transferred to NAV, and the invoice is considered to be issued when the invoice details are closed by the invoicing software. Therefore, the provision of data ends when no data of a given invoice with a specific serial number can be overwritten, which means that its content can only be changed by issuing an invoice with a new number.
Invoices may be made out in Hungarian or in any written foreign language. If the invoice is made out in a language other than Hungarian, in the course of an audit conducted within the framework of administrative tax proceedings, the taxable person issuing the invoice may be obliged to furnish an official Hungarian invoice translation, made at their own expense. However, receipts must be issued in Hungarian.
Unlike e-reporting, it is not mandatory to issue invoices in electronic form. Invoices in Hungary can still be issued using printed invoice forms or an invoicing program (or cash register). However, data from issued invoices must be disclosed in the RTIR System. Manual invoice data must be entered in the online invoice system (Számla platform). The issuance of e-invoices by government suppliers is still voluntary, while public administrations must be able to receive and process electronic invoices.
In general, the RTIR System requires XML format. The tax authority’s version 3.0 XML contains a separate field where invoice issuers can indicate to their customers that the given XML file is not only for reporting to the tax authority, but also qualifies as an e-invoice for the customer.
In other cases such formats as .txt, .csv, .dbf, .mdb, .xsl, .xml, .pdf, and any other print file that contains unformatted text or characters are accepted.
Although electronic invoices, as a means of reporting data, can be found in the system of the tax authority, in this case the tax authority does not undertake to store them in accordance with archiving regulations. Electronic tax invoices must always be stored by the taxpayer. E-archiving can be performed by any method that meets the requirements of the law (ensuring confidentiality, integrity and availability), in particular by one of the following methods:
The documents should be stored for:
