Key Features for Hungarian Invoice Compliance
To ensure compliance with Hungarian invoicing laws, an invoice generator must support specific features. All invoices issued by VAT-registered businesses in Hungary, regardless of value, require real-time reporting to the National Tax and Customs Administration (NAV) via the Online Számla system. This reporting must occur immediately upon issuance. Mandatory fields for invoices include the date of issuance, a unique sequential number, the VAT numbers, full names, and addresses of both the supplier and customer. Additionally, a detailed description of goods or services, quantities, the date of supply (if different from the invoice date), net taxable value, applied VAT rate, and the VAT amount (in HUF if a foreign currency is used) are essential. For NAV reporting, the accepted format is XML, specifically version 3.0, which is highly recommended.
