Understanding Hungarian Invoice Requirements
Issuing compliant invoices in Hungary requires adherence to specific legal and regulatory frameworks, which apply to both electronic and paper formats. Under Hungarian VAT regulations, businesses are generally obligated to issue an invoice for all taxable supplies of goods or services, as stipulated by Article 159 of the VAT Act.
Mandatory elements that must be present on a Hungarian invoice include:
- The date of issuance and a unique sequential number for identification.
- The full name, address, and VAT number of both the supplier and the customer. For domestic sales to taxable persons, the customer's tax number is a specific Hungarian requirement.
- A full description of the goods or services provided, including quantities and unit prices, along with the net taxable value, the applied VAT rate, and the VAT amount. The VAT amount must also be indicated in Hungarian Forints (HUF) if the invoice is issued in a foreign currency.
- The date of supply, if it differs from the invoice issuance date.
- Details supporting any VAT exemption or reverse charge, referencing the relevant legal provision.
- The total gross value of the invoice.
Invoices must be issued within 8 days after the supply date for domestic transactions, or by the 15th day of the month following the supply for intra-Community transactions. If payment is made in cash, the invoice must be issued immediately. Hungary's standard VAT rate is 27%, with reduced rates of 18% and 5% applicable to certain goods and services.
While electronic invoices hold the same legal status as paper invoices, provided they meet authenticity and integrity requirements, the distinction lies primarily in their processing and reporting. Currently, issuing electronic invoices is not strictly mandatory for all B2B and B2G transactions, but real-time reporting (RTIR) of all invoice data to the Hungarian Tax Authority (NAV) is compulsory, irrespective of whether the invoice is paper, PDF, or XML. This data must be transmitted via the NAV Online Invoice System (Számla platform). Importantly, invoices cannot be simply created in generic software like Word or Excel; they must be generated using invoicing software reported to the tax authority or in special pre-printed booklets. Hungary is moving towards mandatory e-invoicing for domestic B2B, intra-EU B2B, and B2G transactions, with a voluntary testing environment expected from 2028. In this future model, the legally authentic invoice will be the machine-readable XML file, even if a paper version is also provided.
